1.0 INTRODUCTION Trans Mountain Pipeline ULC (Trans Mountain) submitted a Facilities Application (the Application) to the Canada Energy Regulator (CER) (formerly the National Energy Board) [NEB]) in December 2013 for the Trans Mountain Expansion Project (“the Project” or “TMEP”). The Application includes Environmental Protection Plans (EPPs), Environmental Management Plans (EMPs) and CER Condition Plan Reports. These plans were developed to communicate environmental procedures and measures to the Project construction and inspection personnel in a clear and concise format. Mitigation measures will be implemented, where warranted, during construction and reclamation of the Project to avoid or reduce potential adverse environmental effects during construction.

Trans Mountain submitted an updated Pipeline EPP on October 1, 2019 (Filing ID C01961). The updated Pipeline EPP was approved by the CER on November 25, 2019 (Filing ID C03225) for Spreads 1 and 2, on January 17 for Spread 3 (Filing ID C04172) on April 16, 2020 (Filing ID C05761) for Spreads 4a, 4b, 5a and 7 and on June 4, 2020 for Spread 5b (Filing ID C06670). Trans Mountain has conducted a comprehensive review of the Facilities EPP, and has updated the mitigation measures to ensure alignment between Project documentation and consistency for all components. In addition, the review included:

• incorporating all relevant commitments made in Information Requests (IRs) and compliance requests; and

• incorporating information from additional field studies and updates, as well as refinements that have been identified since the previous filing of this information.

Revisions made to the Facilities EPP are noted in Table 1.

TABLE 1

VOLUME 3 FACILITIES EPP CER CONCORDANCE TABLE

Section Sub-heading Update/Change Reason Volume 3 - Throughout Throughout Updated dates and revision numbers. Update the Facilities EPP to reflect the

latest revision and submission date. This update does not change the content of the Facilities EPP; therefore, does not affect any commitment made by Trans Mountain.

Volume 3 - Throughout Throughout Updated or removed entity name from “Kinder Morgan Canada” or “KMC” to “Trans Mountain” on the title page, p iii, v, vi, 4-1, 12-2, 12-3, B-4, B-15, B-18(2), B-20.

Project update to reflect the most up to date Company information to the new legal entity. This update does not change the content of the Facilities EPP; therefore, does not affect any commitment made by Trans Mountain.

Volume 3 - Throughout Throughout Acronyms and Abbreviations checked and updated. Update for consistency to ensure that all acronyms within the document are captured, and those not used are deleted. Updates to specific acronyms and abbreviations are discussed in further detail in this Table under – Volume 3 – Abbreviations. This update does not change the content of the Facilities EPP; therefore, this does not change the meaning or affect any commitment made by Trans Mountain.

Volume 3 - Throughout Throughout Grammar, spelling and formatting checked and updated. Specifically, these updates include spelling, grammar, first mentions, table number updates, Appropriate Government Authority names, and general wording updates to improve readability of the Facilities EPP.

Update for accuracy to ensure that the document is correct. This does not change the meaning or affect any commitment made by Trans Mountain.

Volume 3 – Throughout Throughout Replaced “Aboriginal” and “ATK” with “Indigenous” and “ITK” on p i(4), iii, vii, viii, 1-1(2), 1-3(5), 2-1, 2-2(2), 3-1(2), 5-1, 5-2(2), 5-3, 6-6, 6-8(3), B-3(2), B-8(2), B-9(2), B-15(2), B-21(5), B-22(3), B-23(7), B-29, B2-1, F-1(4), F-2, F-5(9), F-6(7), F-7(2), F-8(11), F-9(2), F-10(7), F-12, G-1

Update for consistency and to ensure that the Facilities EPP matches the terminology used in the CER Reconsideration Report. As this is a change in terminology and not the content of the mitigation, this does not change the meaning or affect any commitment made by Trans Mountain.

Volume 3 – Throughout Throughout Moved mitigations to more appropriate sections within the Facilities EPP.

Update for consistency and to improve readability. Specific information on mitigation measures that have been moved are provided in further detail (including new location and page number references) throughout this document. This does not change the meaning or affect any commitment made by Trans Mountain as the mitigation measures are still included in the Facilities EPP.

Volume 3 – Throughout Throughout Updated Activity/Concern heading. Update for clarity. Specific information on the activity/concern headings that have been revised are provided in further detail throughout this document. This does not change the meaning or affect any commitment made by Trans Mountain.

Volume 3 – Throughout Throughout Combined “Topsoil” and “Root Zone Material” into one term “Topsoil.” Defined in the Glossary on p vi, 2-2(2), 6-6(2), 6-9, 7-3(4), 7-4, 8-1(12), 8-2(10), 8-3(2), 9-1(3), 10-1(6), B-11(3), B-12(5), B-13(5), B-24, B-25(3), B-26(7), Detail 4(9), D-2(5), D-3(5), D-2(5), D-5(7), D-6(7), D-7(6), D-8(3), D-9(2).

Update for clarity to ensure that proper soils handling techniques are implemented on all land uses along the Project. The definition for “topsoil” has been edited to include the “root zone material” encountered in non-agricultural land uses. As the revised definition includes both “topsoil” and “root zone material”, this does not change the meaning or affect any commitment made by Trans Mountain.



01-13283-GG-0000-EV-PLN-0013

TABLE 1 Cont’d

Section Sub-heading Update/Change Reason Volume 3 – Throughout Throughout Replaced “MOC process” with “change management

process” on p 7-1. Update for consistency and align with the terminology used throughout other Project documents (e.g., contracts) and ensure construction personnel are accessing the most up to date Project resources. This update is a change in Project terminology, not a change of content, therefore, this does not change the meaning or affect any commitment made by Trans Mountain.

Volume 3 – Throughout Throughout Replaced “ drainage measures” with “drainage, erosion and sediment measures” on p 6-7, 6-9(3), 7-3(3), 7-6, 8-3(2), 9-3.

Update for consistency and add additional detail to all situations that may arise where these mitigation measures may be implemented. This does not result in a change of meaning or affect any commitment made by Trans Mountain, as it adds additional context for construction personnel to understand that these measures will be implemented to control drainage, erosion and sediment.

Volume 3 – Throughout Throughout Replaced “restoration” with “reclamation” on p 7-4. Update for consistency with other Project documentation filed with the CER (e.g., Volume 6.0, Section 9.0 – Reclamation Management Plan [Filing ID A84124]). Reclamation is defined as the reconstruction of disturbed land/ ecosystem to an equivalent capability or state, where the expectation over time is that the reclaimed disturbance/ reconstructed ecosystem will be self-sustaining and will eventually replicate the existing terrain/ ecosystem over the long-term. Reclamation is a more accurate description of the activity; therefore, this does not change the meaning or affect any commitment made by Trans Mountain.

Volume 3 – Throughout Throughout Replaced “a minimum of 1 m” with “adequate” on p 8-3.

Update for clarity and to re-focus on an objective-based mitigation measure. Adequate is defined in the EPP as (Page v of the revised Facilities EPP) “sufficient for a specific need or requirement (e.g., in terms of soil separation, adequate separation is defined as no admixing of topsoil and subsoil)”. The intent of the mitigation measure is to prevent admixing of topsoil and subsoil. While no minimum separation distance is been provided, soil will be stored with a separation distance that does not result in admixing, therefore, this does not change the meaning or affect any commitment made by Trans Mountain and provides measures for Project.

Volume 3 – Throughout Throughout Removed KP range for the burning prohibited area and replaced with Wahleach Pump Station to Burnaby Terminal on p 5-2, 6-8, 7-6, 7-7.

Update for clarity. Areas where there are burning restrictions were previously referenced by KP, which are subject to change with micro routing. Update to stationary facilities to ensure that areas where burning is prohibited are clear.

TABLE 1 Cont’d

Section Sub-heading Update/Change Reason Volume 3 – Throughout Throughout Revised: During construction, inspect these structures

to ensure functionality and repairs will be completed as required (i.e., rain event). on p 8-3, 9-3.

Update for clarity and consistency, as well as to re-focus to an objective-based mitigation measure. Measures throughout the Facilities EPP stated different inspection intervals for drainage, erosion and sediment control measures. Mitigation measures are now consistent to the interval and requirements for inspection of drainage, erosion and sediment control measures. This change does not change the meaning of the mitigation measure and has been updated to ensure that the inspection period for drainage, erosion and sediment control structures is clear, and consistent. This does not affect any commitment made by Trans Mountain.

Volume 3 – Throughout Throughout Updated “NEB” or “National Energy Board” to “CER” or “Canada Energy Regulator” on title page, p i(3), iii(3), vii, 1-1(3), 1-3(5), 2-1, 4-1(2), 4-2, 4-3, 5-1(3), 5-2(5), 6-3, 6-4, 6-6, 11-1(5), 11-2, B-14, B-17, B-20, B2-1, D-9, EDF-16, F-2, F-4, F-5(2),F-7(4), F-8(8), F-10(5), F-11.

Update for clarity. Regulator name has been updated to CER to reflect the new name. This does not change the meaning or affect any commitment made by Trans Mountain.

Volume 3 – Throughout Throughout Replaced Alberta Culture & Tourism to ACMSW. Update for consistency with the appropriate name of the regulator. This does not change the meaning or affect any commitment made by Trans Mountain.

Volume 3 – Table of Concordance

Table 1 Updated introductory paragraph for the Table of Concordance.

Updated for consistency to align with current Project approvals. This update does not change the meaning or affect any commitment made by Trans Mountain.

Volume 3 – Linkage to Other Plans

Table 2 Added table outlining linkages between Plans. Update for clarity and provide construction personnel with a guide to the other Environmental Management Plans, their CER Conditions and scope, as well as where they can be found in the Volumes of Environmental Plans. This does not change the meaning or affect any commitment made by Trans Mountain

Volume 3 – Abbreviations and Acronyms

- Removed: EHS ESA HDD KMC MOC Program’ WHMIS WVMP Replaced: CMP with ECMP NEB OPR with CER OPR ATK with ITK BC MOECCS with BC ENV

Update for consistency to ensure that all acronyms within the document are captured, and those not used are removed. Acronyms were replaced with updated terminology to reflect the most up to date Project information, including Indigenous Traditional Knowledge. This does not change the meaning or affect any commitment made by Trans Mountain.

TABLE 1 Cont’d

Section Sub-heading Update/Change Reason Volume 3 - Introduction Figure 1.1-1 Updated route and dates. Update the Facilities EPP. Figure 1 was

updated to provide the most current version of the pipeline route. This does not change the meaning or affect any commitment made by Trans Mountain.

Volume 3 - Introduction Section 1.2 Purpose Revised: The purpose of the Facilities EPP is to communicate environmental procedures and mitigation measures to construction and inspection personnel in a clear, concise format. These potential mitigation measures will be implemented, where applicable, during construction of the facilities to avoid, mitigate or reduce potential adverse environmental effects.

Updated to reflect the mitigation hierarchy (avoid, mitigate, reduce) as well as ensure that mitigation measures are implemented, where they applicable, during construction of the facilities. This does not change the meaning or affect any commitment made by Trans Mountain.

Volume 3 - Introduction Section 1.2 Purpose

Removed the Condition references. Update the Facility EPP. Condition references were deleted as redundant, as the current revision is not a requirement under CER Condition 78. This does not change the meaning or affect any commitment made by Trans Mountain.

Volume 3 - Introduction Section 1.3 Traditional Ecological Knowledge and Traditional Land Use

Deleted “as a means”. Updated for clarity, as ITK is not a means to preserve, but is the preservation of information. ITK utilizes different means to gather this information. This does not change the meaning or affect any commitment made by Trans Mountain.

Volume 3 - Introduction Section 1.3 Traditional Ecological Knowledge and Traditional Land Use

Added: Other relevant information on sacred and cultural sites, arising from Phase III Consultation, has been incorporated into an updated filing of Condition 100 – Heritage Resources and Sacred and Cultural Sites Plan (Filing ID C01853). The Facilities EPP has been updated to include sacred and cultural sites identified in the Condition 100 filing, where relevant.

Update the Facilities EPP to include a reference to the updating CER Condition 100 Filing. As these commitments were included in existing Project documents, this does not change the meaning or affect any commitment made by Trans Mountain.

Volume 3 – EPP Organization Section 2.1 Organization

Revised: The Facilities EPP identifies the mitigation measures that will be implemented, where applicable, during pre-construction, construction and post-construction activities associated with Project facility development. Contingency Plans (Appendix B) are provided to address unforeseen events or conditions that may arise during these activities. Management Plans (Volume 6 of the Environmental Plans) describe the specific environmental management procedures and mitigation measures that build on the Facilities EPP and may apply to ongoing construction activities.

Update for clarity, and to allow flexibility, as not all mitigation for a given activity will be necessary for that particular activity at every location. As environmental procedures and mitigation measures will be implemented where required, based on site-specific conditions, this does not change the meaning or affect any commitment made by Trans Mountain.


Added: To facilitate construction, the mitigation measures from these plans have been consolidated in Appendix G of the Pipeline EPP (Volume 2 of the Environmental Plans).

Update for consistency, as mitigation measure contained within the Environmental Management Plans (Volume 6 of the Environmental Plans) have been consolidated and updated in Appendix G of the Pipeline EPP (Filing ID C01961) (Compliance Letter No. 10 Filing ID C03225). This statement provides construction personnel with the location of the updated mitigation measures previously approved by the CER, therefore this does not change the meaning or affect any commitment made by Trans Mountain.


Revised: This version of Facilities EPP is organized as follows.

Updated for clarity to describe the included sections and appendices of the Facilities EPP. This update does not change the meaning or affect any commitment made by Trans Mountain.

TABLE 1 Cont’d

Section Sub-heading Update/Change Reason Volume 3 – EPP Organization Section 2.1

Organization Revised the title of Section 5 “Section 5.0 Notifications and Permitting.

Update for clarity. The title of Section 5.0 was updated to reflect the contents of this section, as it includes both notifications and construction permits. This does not change content or mitigation measures, and therefore this does not change the meaning or affect any commitment made by Trans Mountain.


Added: Appendix F-1 contains the records of stakeholder notifications for the Facilities EPP.

Update for clarity. Description of Appendix F-1 was previously missing in Section 2.1. This update does not change the meaning or affect any commitment made by Trans Mountain.

Volume 3 – Consultation and Engagement

Section 3.0 Added: in the June 1, 2017 filing of the Facilities EPP (Filing ID A84142).

Update for clarity on the feedback process for the Facilities EPP. This update does not change the meaning or affect any commitment made by Trans Mountain.

Volume 3 – Consultation and Engagement

Section 3.0 Added: Engineering design changes have been issued since the submission of the August 2018 Facilities EPP (Filing ID A93475). The engineering design changes have been reviewed, and additional mitigation measures were required in the Facilities EPP and subsequently added. Additional information related to consultation activities is provided in Condition 96 (Filing ID A84533).

Update the Facilities EPP to reflect when the consultation and engagement activities were conducted on the Facilities EPP. This update does not change the meaning or affect any commitment made by Trans Mountain.

Volume 3 – Environmental Compliance

Section 4.0 Revised: Trans Mountain has developed an Environmental Compliance Management Plan (ECMP) to support construction execution and ensure full compliance with applicable legal requirements, regulations, permits, approval Conditions and commitments made by Trans Mountain. In addition, an Environmental and Compliance Education Training Program has been designed to ensure that all Project personnel are trained and aware of roles and responsibilities. The Organizational Structure (previously found in subsection 4.3 of this Facilities EPP) is now being prepared for CER Condition 88.

Update for clarity as the location of information within the ECMP as well as to reduce redundant or repeated information. References to locations of information have been updated to reflect the most up to date and relevant information for the Facilities EPP. As this section serves as a reference to the Project ECMP, this does not change the meaning or affect any commitment made by Trans Mountain.


Section 4.0 Revised: Trans Mountain established the Integrated Safety and Loss Management System (ISLMS) pursuant to Section 6 of the 2020 Canadian Energy Regulator Onshore Pipeline Regulation (CER OPR). The ISLMS applies to Company activities including the design, construction and operation of a pipeline and facilities. The ISLMS outlines Trans Mountain’s commitment to establishing, implementing and monitoring processes and controls to ensure that it is conducting business in a safe, environmentally responsible and sustainable manner. Information on the ISLMS was previously found in subsection 4.2 of this Facilities EPP, and has been re-located to the ECMP.

Update for redundancy, by removing information that is not relevant for construction, or only contextual. As this section serves as a reference to the Project ECMP, this does not change the meaning or affect any commitment made by Trans Mountain.


Section 4.0 Revised: During the course of construction, it may be necessary to modify or create new procedures to address site conditions not previously identified in the Facilities EPP. Field-based decision-making and Project-approved contingency plans will be implemented to address unexpected conditions as described in Field Level Environmental Change Management section of the ECMP.

Update for clarity on the information required to modify or create new procedures, should the need arise during construction. As this section serves as a reference to the Project ECMP, this does not change the meaning or affect any commitment made by Trans Mountain.

Section Sub-heading Update/Change Reason Volume 3 – Environmental Compliance

Section 4.1 Potential Permits, Approvals and Authorizations

Revised: Trans Mountain will work with the Appropriate Government Authorities to obtain the necessary environmental permits, approvals and authorizations prior to the commencement of applicable construction activities. Applicable permits, approvals and authorizations are provided in Tables 4-1 and 4-2, respectively. Trans Mountain will work with Municipalities to provide filing demonstration of conformance applicable to the Project prior to the commencement of construction. While these tables are comprehensive, they are not exhaustive and additional permits may be required. Permits, approvals and authorizations will be available throughout the construction and commissioning phases of the Project through the Permit Binder.

Update the Facilities EPP to reflect the current status of Project permits, approvals and authorizations, as well as the most up to date plan to organize permit information for construction personnel. The updates remove “hard copy” binders to allow construction personnel to use electronic binders as an option to reference Project materials and permits. This does not change the meaning or affect any commitment made by Trans Mountain.


Table 4-1 Revised: “NEB” to “CER” and added: The Project has received approval under Section 52 of the NEB Act.

Update to reflect the regulator name (CER) and Act and add clarification that the Project has been approved under a previous Act. This does not change the meaning or affect any commitment made by Trans Mountain.


Table 4-1 Removed Parks Canada as a regulatory authority. Update for consistency. This does not apply to construction of the facilities as no facilities are proposed with Parks Canada areas. This does not change the meaning or affect any commitment made by Trans Mountain.


Table 4-1 Revised Fisheries Act Section 35(2): Self-Assessment, Request for Review and Application for Authorization Authorization under Section 35(2) of the Fisheries Act will be required if self-assessment determines that construction will result in the death of fish or the HADD of fish habitat.

Update to reflect the most up to date wording included in Section 35(2) of the Fisheries Act. This does not change the meaning or affect any commitment made by Trans Mountain.


Table 4-2 Removed BC Parks as a regulatory authority. Update for consistency. This does not apply to construction of the facilities as no facilities are proposed within BC Parks. This does not change the meaning or affect any commitment made by Trans Mountain.

TABLE 1 Cont’d

Section Sub-heading Update/Change Reason Volume 3 – Section 5.0 Introduction Clarified roles and responsibilities for notifications by

revising: Communication of the construction schedule and timing of specific construction activities will facilitate notification of upcoming activities and allow Appropriate Government Authorities, Indigenous groups, landowners/tenants and other applicable interested parties to plan, as appropriate, for construction activities in the area of interest. The following measures will be implemented by Trans Mountain.

Update for clarity based on other Project documents (e.g., contract). The Company is responsible for notifications, and ensuring permits are acquired prior to a specific construction activity, therefore, this does not change the meaning or affect any commitment made by Trans Mountain.

Volume 3 – Section 5.0 Objectives Removed: work adheres to applicable approval conditions;

Update for clarify, as approvals may not include notifications. Therefore, this does not change the meaning or affect any commitment made by Trans Mountain.

Volume 3 – Section 5.0 Federal Authorities Removed: Submit monthly construction progress reports to the NEB as per NEB Condition 106, from commencement of construction until after commencing operations. Monthly reports to include any environmental issues and non-compliances that occurred; and measures undertaken to resolve these environmental issues and non-compliances.

Update for redundancy, as CER Condition 106 requires monthly construction progress reports, which are not a notification or permit required for construction. As this is not a construction permit or notification, this does not change the meaning or affect any commitment made by Trans Mountain.

Volume 3 – Section 5.0 Federal Authorities Removed: A list of the potential Federal permits, approvals and authorizations is provided in Table 4.1-1. Additional permits beyond those listed in Table 4.1-1 may be required.

Updated for redundancy, as Table 4.1 described earlier contains necessary Federal permits.

Volume 3 – Section 5.0 Federal Authorities Added Notify DFO (see Appendix A) if blasting near or within a watercourse is necessary. Apply for appropriate regulatory approvals under the Fisheries Act.

Updated to include blasting measures should blasting occur at facility sites in proximity to watercourses. This does not change the meaning or affect any commitment made by Trans Mountain.

Volume 3 – Section 5.0 Federal Authorities Added: In the case of permanent loss of wetland function, offsets will be discussed with ECCC as per Condition 41.

Updated for clarity. Wetland offset measures are being introduced in the Facilities EPP and require consultation with Federal authorities (ECCC). As Trans Mountain is required to consult for wetland offsets for the Project, this does not change the meaning or affect any commitment made by Trans Mountain.

Volume 3 – Section 5.0 Provincial Authorities- Alberta

Removed: A list of the potential provincial permits, approvals and authorizations is provided in Table 4.1-2. Additional permits beyond those listed in Table 4.1-2 may be required.

Updated for redundancy, as Table 4.2 described earlier contains necessary Provincial permits.

Volume 3 – Section 5.0 Provincial Authorities- Alberta

Removed: Trans Mountain will ensure a copy of the applicable TDL approval is on-site prior to withdrawal. Adhere to all Conditions of the TDL

Update for consistency and redundancy. The requirement to have permits available are outlined in subsection 4.1 on Pages 4-1 to 4-3 and does not need to be repeated. This does not change the meaning or affect any commitment made by Trans Mountain as the requirement is already present in the Facilities EPP.

Volume 3 – Section 5.0 Provincial Authorities- BC

Added: by the BC EAO Permit Conditions Update for clarity on where notifications to BC EAO are required (i.e., as outlined in the Permit Conditions. This does not change the meaning or affect any commitment made by Trans Mountain.

Volume 3 – Section 5.0 Provincial Authorities- BC

Removed: Ensure a copy of the required approvals is on-site prior to withdrawal. Adhere to all approval Conditions.

Update for consistency and redundancy. The requirement to have permits available are outlined in subsection 4.1 on Pages 4-1 to 4-3 and does not need to be repeated. This does not change the meaning or affect any commitment made by Trans Mountain as the requirement is already present in the Facilities EPP.

TABLE 1 Cont’d

Section Sub-heading Update/Change Reason Volume 3 – Section 5.0 Provincial

Authorities- BC Revised: Obtain the required Water Sustainability Act approvals under Sections 10 and 11 from the BC OGC for the short-term use of water and changes in and about a stream or wetland. A written authorization (i.e., change approval) is required to make complex changes in and about a stream.

Updated for clarity as to how to obtain Water Sustainability Act approvals. Terminology has been updated to align with terminology used to apply for a change approval. This does not change the meaning or affect any commitment made by Trans Mountain as the requirement is already present in the Facilities EPP.

Volume 3 – Section 5.0 Municipal Authorities Revised: The existing Trans Mountain pipeline (TMPL) is Federally regulated by the CER. As a CER Federally regulated entity, the TMPL requires approval from the CER prior to the construction of the TMEP. The TMPL also complies with all ancillary legislation unless it conflicts with or frustrates Federal legislation, in which case the TMPL will comply with Federal legislation as ultimately determined by the CER.

Update for clarity. Regulator name has been updated to CER to reflect the new name. The affiliation of the CER to the Government of Canada is not relevant to environmental protection or Municipal permits and authorizations. This does not change the meaning or affect any commitment made by Trans Mountain.

Volume 3 – Section 6.0 Introduction Revised: This section describes the mitigation measures that will be implemented, where applicable, by Trans Mountain, its Contractors and Subcontractors prior to the commencement of construction activities and will be followed for each phase of facility construction to ensure protection of environmental features, as well as delineation of facility boundaries.

Update for clarity, as measures are not always warranted based on site-specific conditions, and mitigation measures will be implemented when they are required. This does not affect any commitment made by Trans Mountain.

Volume 3 – Section 6.0 Review Mitigation Measures for Environmental Features

Revised wording The Environmental Inspector will review mitigation measures to be implemented during construction to avoid or reduce effects on environmental features (i.e., rare plants and rare ecological communities, wildlife species at risk, archaeological features, TLU sites and other sensitive or cultural features) on or in proximity to the facility site. This review will be conducted in advance of construction at locations where any of the above features are known to be present to ensure that suitable and appropriate procedures have been selected and can be implemented prior to construction, where applicable.

Update for consistency with the mitigation measures in the Pipeline EPP (CER Condition 72) to ensure mitigation measures, procedures protocols and standards are consistent for all components of the Project. Intent of the mitigation measure is not changed, but wording revised to improve readability and ensure consistency. This does not affect any commitment made by Trans Mountain.

Volume 3 – Section 6.0 Review Mitigation Measures for Environmental Features

Revised: The Environmental Inspector will document construction methods, decisions related to implementation and location of mitigation measures and final reclamation measures and issues encountered, as well as communication records for discussions with Appropriate Government Authorities.

Updated “BC MFLNRORD” to “Appropriate Government Authorities” for clarity and to ensure communications and discussions are had with all Appropriate Government Authorities as required, based on the reclamation measures or issues encountered.

Volume 3 – Section 6.0 Species at Risk Revised: Ensure that mitigation measures concerning wildlife and plant species at risk are communicated to construction personnel and supported by an Environmental Inspector. Refer to information on species at risk presented in the RSMT in Appendix D and the Environmental Facility Drawings in Appendix E for locations of, and mitigation measures for wildlife and vegetation species at risk or their habitats.


Volume 3 – Section 6.0 Species at Risk Revised: Report observations of species at risk immediately to an Environmental Inspector. Environmental Inspector will record the location in the daily reports and locate and mark sightings for future reference in Post-Construction Environmental Monitoring documentation.

Update to align with the terminology in CER Condition 140 for Post-Construction Environmental Monitoring.

Section Sub-heading Update/Change Reason Volume 3 – Section 6.0 Wildlife Revised: Where feasible, initiate or complete clearing

and construction activities outside of the migratory bird nesting period, where feasible, to reduce the risk of encountering migratory birds nesting on the facility site (Environment Canada 2018).

Update for redundancy. Migratory bird nesting periods are outlined per spread in the RSMTs (Appendix D of the Facilities EPP). As timing restrictions are still included as part of the Project documentation, this does not change the meaning or affect any commitment made by Trans Mountain.

Volume 3 – Section 6.0 Wildlife Revised: Clear or mow areas of vegetation (in particular, trees, grasslands, pasture) outside of the migratory bird nesting period to reduce the potential of nesting birds where work is scheduled to occur during the migratory bird nesting period.


Volume 3 – Section 6.0 Wildlife Removed: The red-tailed hawk that was located adjacent to the Burnaby Terminal has removed (i.e., when the nest was not occupied), therefore mitigation for this feature is no longer necessary.

Update for accuracy, as the red-tailed hawk nest located adjacent to Burnaby Terminal has been removed. This does not change the meaning or affect any commitment made by Trans Mountain.

Volume 3 – Section 6.0 Wildlife Revised: Implement the Wildlife Species of Concern Encounter and Discovery Contingency Plan (Appendix B) in the event of an encounter with wildlife during construction, either at the construction site or on the commute to or from the construction site. Report any incidents or collisions with wildlife to Environmental Inspector who will consult with the Appropriate Government Authorities and the local conservation officer, if applicable (Wildlife Conflict Management Plan in Section 6.5 of Volume 6 of the Environmental Plans). Follow the incident reporting processes outlined in the Project Emergency Response Plan (ERP) (CER Condition 89) for safety-related incidents.

Update for clarity by moving the reference to the Wildlife Conflict Management Plan within the measure to follow “consult with Appropriate Government Authorities, if applicable”. As the reference to the Wildlife Conflict Management Plan is still included in the mitigation measure, this does not change the meaning or affect any commitment made by Trans Mountain.

Volume 3 – Section 6.0 Wildlife Added: All Project workers are strictly prohibited from hunting, fishing, trapping and gathering plants within or along the construction footprint and at any other construction sites including but not limited to Trans Mountain facilities and premises. Workers are prohibited from possessing or storing any firearm, bows, or crossbows, whether or not concealed, at a Project worksite, on any Project owned or leased premises (including construction camps), or in work vehicles. Fishing equipment, snowmobiles and all-terrain vehicles not used for work on the Project are prohibited at worksites and in work vehicles. Worker use and enjoyment of the environment when off-duty must be conducted in full compliance with all laws and regulations.

Update to the Facilities EPP to match Trans Mountain’s updated Hunting and Fishing Policy. This measure expanded to include fishing and hunting into one measure to prohibit hunting, fishing, and the use of recreational vehicles at the Project sites. This measure also prohibits the collection of plants, which was not previously included in the Facilities EPP. This does not change the meaning or affect any commitment made by Trans Mountain.

Volume 3 – Section 6.0 Heritage Resources Revised: Refer to RSMT for locations of known historical resources and associated mitigation measures in Appendix D.

Update for accuracy to ensure that the document is correct. This does not change the meaning or affect any commitment made by Trans Mountain.

TABLE 1 Cont’d

Section Sub-heading Update/Change Reason Volume 3 – Section 6.0 Heritage Resources Revised: For more information, refer to Heritage

Resources and Sacred and Cultural Sites Plan prepared for CER Condition 100 (Section 2.4 of Volume 6 of the Environmental Plans).

Update for clarity. Site-specific information for heritage resources is located in Condition 100, and the RSMT (Appendix D). The Facility EPP provides reference to the RSMT in the previous mitigation measure “Refer to environmental RSMTs for locations of known historical resources and associated mitigation measures in Appendix D.” As a reference to the known locations are included in the Facilities EPP, this does not change the meaning or affect any commitment made by Trans Mountain.

Volume 3 – Section 6.0 Waste and Hazardous Material Storage

Revised: Personnel will be made aware of their responsibilities for proper handling, identification, documentation and storage of hazardous and non-hazardous materials

Update for clarity to ensure that all hazardous materials, not just wastes are handlined in accordance with the appropriate regulatory guidelines. This update does not change any commitment made by Trans Mountain, as hazardous materials includes wastes and non-waste materials.


Removed wording Personnel handling waste or hazardous materials will possess valid Workplace Hazardous Materials Information System (WHMIS) training (Health Canada 2015).

Update for redundancy. As this is not an environmental mitigation measure, this does not change the meaning or affect any commitment made by Trans Mountain.


Revised: Where feasible, store fuel, oil or hazardous wastes in secondary containment located greater than 100 m from a watercourse or wetland.

Update for clarity and to ensure that all hazardous substances are stored with proper secondary containment. Some facility sites are located within 100 m of watercourses or wetlands, therefore “where feasible” was added. This update serves to add additional detail on containment at sites located within 100 m of watercourses, therefore, this does not change the meaning or affect any commitment made by Trans Mountain.


Revised: When using portable storage devices (e.g., bulk tanks containing a petroleum or allied petroleum product, or other hazardous materials as applicable) exceeding 1,000 L (or 1 m3), single walled bulk tanks shall be housed within secondary containment (e.g., bermed area lined with an impervious polyethylene liner) or another form of secondary containment. The secondary containment will be designed and sized in accordance with applicable Provincial and/or Federal requirements. Tertiary containment will not be required for bulk tanks with integral secondary containment. Ensure that collected surface water (e.g., snow melt, rain water) is removed in a timely manner to maintain sufficient containment if a spill occurred. If there is visible hydrocarbon sheen, the water in the containment structure will be collected for proper storage and disposal at a Trans Mountain-approved waste disposal facility and in accordance with the Waste Management Plan (Section 3.1 of Volume 6 of the Environmental Plans) and the Spill Contingency Plan (Appendix B).

Update for clarity with the specific requirements of portable storage devices and secondary containment. The updates provide better descriptions and detail of the storage tanks, materials, secondary containment, volume, tertiary containment, and surface water collection for portable storage devices. As the updates were made to provide additional detail of the requirements, this does not change the meaning or affect any commitment made by Trans Mountain.

TABLE 1 Cont’d

Section Sub-heading Update/Change Reason Volume 3 – Section 6.0 Waste and

Hazardous Material Storage

Revised: Maintain documentation on all hazardous materials being stored at the facility sites.

Update for clarity to ensure that all hazardous materials, not just wastes are handlined in accordance with the appropriate regulatory guidelines. This update does not change any commitment made by Trans Mountain, as hazardous materials includes wastes and non-waste materials.


Revised: Visually inspect fuel tanks on a regular basis as well as when the tank is refilled. Maintain inspection records for each tank. Take remedial action as soon as a crack, dent or leak is detected.

Update for clarity. Inspection records will be maintained for all fuel tank inspections and remedial action will be taken as soon as a crack, dent or leak is detected, not only for leaks. This does not change the meaning or affect any commitment made by Trans Mountain.

Volume 3 – Section 6.0 Waste Disposal Revised: Collect construction debris and other waste materials on a regular basis and dispose of it at a Trans Mountain-approved facility and in accordance with the Spill Contingency Plan (Appendix B) and the Waste Management Plan (Section 3.1 in Volume 6 of the Environmental Plans). Ensure wastes are recycled where practical

Update for clarity by providing guidance to which facilities are approved for waste disposal in accordance to the Waste Management Plan and procedures on recycling waste. This does not change the meaning or affect any commitment made by Trans Mountain.

Volume 3 – Section 6.0 Scheduling Revised: Review and abide by all applicable timing restrictions and least risk biological windows as shown in the RSMT and Environmental Facility Drawings (Appendices D and E), where feasible. When construction activities are scheduled within a wildlife timing window, ensure necessary regulatory approvals are in-place, if required.

Update for clarity on work within a wildlife timing window by revising wording from “outside preferred construction” to “within a wildlife timing” window, as the mitigation measures apply to the wildlife window, not the preferred construction window. This does not change the meaning or affect any commitment made by Trans Mountain.

Volume 3 – Section 6.0 Roads and Access Revised: Confine construction activities to the allotted construction footprint. Restrict construction traffic to existing roads.

Update for clarity, as the Project Footprint is defined as extra temporary workspace, therefore this does not need to be repeated. This does not change the meaning or affect any commitment made by Trans Mountain.

Volume 3 – Section 6.0 Construction Traffic Revised: Where feasible, transport construction personnel to and from the facility site by multi-passenger vehicles to limit the potential for vehicle/wildlife interactions. Contractor work force will be encouraged to use multi-person vehicles, while those requiring mobility (e.g., supervisory roles, inspection roles) will need to travel independently.

Update for clarity by adding “where feasible”. Examples of personnel who would be required to travel independently were included in this measure previously, therefore this does not change the meaning or affect any commitment made by Trans Mountain.

Volume 3 – Section 6.0 Construction Traffic Revised: “Implement wheel washing for equipment leaving the facility site and entering public roads, where warranted. Shovel and sweep clean, as quickly as practical, any mud, soils debris or foreign material tracked onto roads from vehicles leaving the construction site.“

Update for redundancy. Cleaning requirements leaving the construction site are outlined in the Weed and Clubroot Environmental Specifications document. This does not change the meaning or affect any commitment made by Trans Mountain.

Volume 3 – Section 6.0 Weeds Revised: Clean equipment (i.e., shovel and sweep, pressurized water, air chisels) involved in topsoil handling at weed-infested sites prior to leaving the location.

Update for redundancy by deleting “Clean equipment involved in topsoil handling at weed infested sites prior to leaving the location.” As this statement is repeated in the measure. As this statement is included in the measure, this does not change the meaning or affect any commitment made by Trans Mountain.

TABLE 1 Cont’d

Section Sub-heading Update/Change Reason Volume 3 – Section 6.0 Use of Herbicides Revised: Prohibit the use of herbicide within 30 m of

known rare plant populations or rare plant communities. Spot spraying, wicking, mowing or hand-picking are acceptable weed control measures in proximity to rare plants and rare plant communities.

Update for consistency with commitments made in the Pipeline EPP (CER Condition 72), and ensure that herbicide use is prohibited within rare plant communities. As the wording has changed to strengthen the mitigation measure, this does not change the meaning, or affect any commitment made by Trans Mountain.

Volume 3 – Section 6.0 Use of Herbicides Revised: Notify potentially affected Indigenous groups prior to the use of herbicides.

Trans Mountain has discussed with herbicide application with Indigenous groups where concerns were raised. Where applicable, results of consultation have been taken into consideration in the Weed and Vegetation Management Plan. The intent of the Facilities EPP is to highlight the notification needs rather than ongoing consultation requirements with Indigenous groups, which are addressed in CER Condition 6 and CER Condition 97.

Volume 3 – Section 6.0 Watercourses and Wetlands

Revised: unless otherwise approved by Trans Mountain.

Update for clarity. Previous wording did not indicate who would provide approval for change. As approval is still required for changes in mitigation at watercourses and wetlands, this does not change the meaning, or affect any commitment made by Trans Mountain.


Removed: Maintain sediment fences in place at wetland boundaries, where warranted, until a vegetation cover is established, or the surrounding area is stabilized.

Updated for redundancy. Measure immediately above states “Install and maintain appropriate drainage, erosion and sediment control measures to prevent sediments from being transported into watercourses and wetlands”. As this measure is still included in the Facilities EPP, this does not change the meaning or affect any commitment made by Trans Mountain.”


Added: Ensure adequate drainage by maintaining the proper grade and installing adequate culverts, as required. Minimize facility footprint in wetlands, where practical. The Environmental Inspector(s) or designate will clearly identify the perimeters of the identified wetland, if the potential exists for Project activities to impact the wetlands. Reduce the removal of vegetation in wetlands to the extent possible. Install a temporary sediment barrier (e.g., sediment fences), where warranted, to eliminate the flow of sediment from disturbed areas into adjacent wetland areas. Replant salvaged trees/shrubs along the disturbed riparian margins of the wetland as directed by the Environmental Inspector(s).

Updated for the revised footprint at Sumas Terminal to ensure measures are in place for potential wetland disturbance as outlined in the Wetland Survey and Mitigation Plan prepared for CER Condition 41 (Filing ID A90909) and the measures outlined in the Pipeline EPP to reduce wetland disturbance.

Volume 3 – Section 6.0 Traditional Land and Resource Use

Revised: Implement the contingency measures identified in the TLU Sites Discovery Contingency Plan (Appendix B) in the event TLU sites not previously identified are found during facility construction. Notify an Environmental Inspector who will collaborate with an Indigenous Monitor for appropriate mitigation measures, where warranted.

Update for clarity, as the Environmental Inspector will collaborate with the Indigenous Monitor for appropriate mitigation, which will ensure protection of the features. This does not change the meaning or affect any commitment made by Trans Mountain.




01-13283-GG-0000-EV-PLN-0013

TABLE 1 Cont’d

Section Sub-heading Update/Change Reason Volume 3 – Section 6.0 Drainage Removed: Reduce the potential for soil erosion by

water during construction activities by avoiding ponding of water or the unintentional channelization of surface water flow.

Update for redundancy. Erosion and sediment control mitigation presented under the heading Drainage, Erosion and Sediment Control Section 6.0 on Page 6-9 accounts for managing these scenarios. This does not change the meaning or affect any commitment made by Trans Mountain as these mitigation measures is still included in the Facilities EPP.

Volume 3 – Section 6.0 Drainage Revised: Inspect constructed water conveyance installations (e.g., ditches and culverts) and ensure that they are functioning appropriately. Check for blockages and any damages to determine if repairs are required. Take appropriate action prior to and during spring break-up to clear culverts blocked by ice or debris.

Update for clarity and to ensure that construction personnel understand what is required when inspecting the water conveyance structures. This does not change the meaning or affect any commitment made by Trans Mountain, as it serves to add detail on inspection requirements.

Volume 3 – Section 6.0 Drainage, Erosion and Sediment Control

Revised: Install drainage, erosion and sediment control structures and materials as approved by an Environmental Inspector. Implement structures and materials (e.g., subsoil berm or sediment fencing) as outlined in the Soil Erosion and Sediment Control Contingency Plan (Appendix B) to ensure that sediments in surface water draining from the facility site do not adversely affect the surrounding terrain, watercourses or wetlands. In particular, control erosion on grade cuts adjacent to the development zone at facility sites.


Volume 3 – Section 6.0 Drainage, Erosion and Sediment Control

Revised: Maintain erosion and sediment control devices at all sites that are no longer in use including: • temporary roads; • borrow sites; • spoil disposal sites; • stock pile sites; and • work pads.”

Update for clarity and to improve wording of the mitigation measure. As erosion and sediment control devices will still be maintained or removed, this does not change the meaning or affect any commitment made by Trans Mountain.

Volume 3 – Section 6.0 Spill Prevention Revised: Maintain appropriate spill equipment at work sites.

Update for redundancy. “All” is not required in the context of maintaining appropriate spill equipment at the work sites. This does not change the meaning or affect any commitment made by Trans Mountain, as the appropriate spill equipment will be maintained for the activities being conducted at worksites.

Volume 3 – Section 6.0 Spill Prevention Revised: Store bulk hazardous waste or hazardous materials in accordance with applicable regulatory requirements Handle all hazardous materials in accordance with applicable Workplace Hazardous Materials Information System protocols.

Update for clarity and to ensure that all hazardous substances are stored with proper secondary containment. This update serves to add additional detail on containment, therefore, this does not change the meaning or affect any commitment made by Trans Mountain.

Volume 3 – Section 6.0 Spill Prevention Revised: Ensure that fuel, lubricating fluids, hydraulic fluids, methanol, antifreeze, herbicides, biocides or other chemicals are not intentionally released on the ground or into watercourses, wetlands or lakes. In the event of a spill, implement the Spill Contingency Plan (Appendix B).

Update for clarity. “During construction” was deleted to ensure that mitigation measure is implemented during all phases of construction. “Dumped” was replaced with “intentionally released” to ensure all intentional releases are included. As these edits serve to strengthen the measure, this does not change the meaning or affect any commitment made by Trans Mountain.

Volume 3 – Section 6.0 Spill Prevention Revised: Conduct re-fuelling a minimum of 100 m from any watercourse or wetland, unless otherwise approved by an Environmental Inspector. Employ the following measures to limit the risk of fuel spills.

Update for clarity as the measures listed following this statement reduce the risk of spills, not just those in water. This does not change the meaning or affect any commitment made by Trans Mountain.



01-13283-GG-0000-EV-PLN-0013

TABLE 1 Cont’d

Section Sub-heading Update/Change Reason Volume 3 – Section 6.0 Spill Prevention Added: All fuel nozzles are to be stored in a secure

manner to prevent drips and spills. Fuel nozzle secured within a receptacle to collect incidental drips after fuelling.

Update for consistency and to reduce the risk of a release to the environment by ensuring that equipment is stored in an appropriate manner. As this mitigation measure was added to reduce the risk of a release, this does not change the meaning or affect any commitment made by Trans Mountain.

Volume 3 – Section 7.1 Introduction Revised: This section describes the mitigation measures that will be implemented where applicable by Trans Mountain, its Contractors and Subcontractors prior to the commencement of facility construction to ensure protection of environmental resource features.


Volume 3 – Section 7.1 Extra Temporary Workspace

Removed: In the event that a change to the construction footprint is deemed necessary (e.g., increase in TWS), the Construction Manager and Lead Environmental Inspector will work through the Project MOC process in consultation with the Project Director to determine what additional approvals and notifications may be required. Added: Follow the Project change management process for modifications or additions to ETWS.

Update for redundancy as measures for ETWS are outlined in the Project change management process. As the procedures are still included as part of the Project documentation, this does not change the meaning or affect any commitment made by Trans Mountain.

Volume 3 – Section 7.1 Construction Documentation

Removed Construction Documentation Section. Removed measure: Refer to measures regarding Facilities EPP distribution provided in the CMP (Volume 10 of the Environmental Plans) and ensure applicable documents are kept at the construction field office for the facility.

Update for consistency and redundancy. References to the distribution of construction documentation for environmental features is included in Section 4.0 of the Facilities EPP on Page 4-1, as well as under the heading Review Mitigation Measures for Environmental Features on Page 6-1. As mitigation measures are included for the distribution of the Facilities EPP and Environmental Alignment Sheets are included in the EPP, this does not change the meaning or affect any commitment made by Trans Mountain.

Volume 3 – Section 7.1 Staking/Flagging/ Fencing

Revised: Stake or flag environmental features and buffers (e.g., archaeological site, rare plant species and wildlife habitat features) on or adjacent to the facility site to avoid the site. Refer to the RSMT and Environmental Facility Drawings (Appendix D and Appendix E, respectively) for the locations of identified environmental features. Ensure staking, flagging or snow fencing is maintained during construction.

Update for clarity. Environmental features will be flagged prior to construction, as well as during construction, as they are encountered. Flagging, staking or fencing will be maintained. This does not change the meaning or affect any commitment made by Trans Mountain.


Removed: Confirm locations of environmental features and ensure staking, flagging or snow fencing is maintained during construction. Prior to commencement of clearing or construction activities, ensure boundary and environmental feature flagging/staking has been surveyed and remains intact.

Update for redundancy. Measures related to maintenance of feature staking/flagging are in the revised measure above. As this mitigation measure is still included in the Facilities EPP, this does not change the meaning or affect any commitment made by Trans Mountain as mitigation has not changed.


Moved: Stake and label topsoil/ root zone material and subsoil stockpiles” from Staking/Flagging/Fencing to Signage in Section 8.0.

Update for consistency. This measure was moved from subsection 7.1 (Survey) to Section 8.0 (Topsoil Material Handling and Grading) on Page 8-1, as it will be implemented following topsoil salvage activities. As this measure is still included in the Facilities EPP, this does not change the meaning or affect any commitment made by Trans Mountain.



01-13283-GG-0000-EV-PLN-0013

Page 17

TABLE 1 Cont’d

Section Sub-heading Update/Change Reason Volume 3 – Section 7.1 Signage Revised: Post signs in the vicinity of environmental

features to alert construction personnel of their presence and to ensure their protection. Recommended setback distances are resource-specific and should be determined in consultation with an Environmental Inspector and/or Resource Specialist, if required. Use site identification numbers to ensure confidentiality and protection of resources, where warranted.

Update for accuracy by adding “Use site identification numbers to ensure confidentiality and protection of resources, where warranted” to ensure that sensitive or confidential features are protected. This does not change the meaning or affect any commitment made by Trans Mountain as mitigation has not changed.

Volume 3 – Section 7.2 Introduction Revised: The following mitigation measures will be implemented, where applicable, by Trans Mountain, its Contractor and Subcontractors on all access roads during the construction of facilities.


Volume 3 – Section 7.2 Access Road Selection

Revised: Use existing access roads and trails, where available and can be safely and efficiently used to transport personnel and equipment rather than develop new access.

Update for clarity, and to focus on an objective-based mitigation measure. The intent of the measure has not been changed, but the grammar has been improved to ensure understanding. This does not affect any commitment made by Trans Mountain.

Volume 3 – Section 7.2 Wildlife Revised: Report all wildlife incidents to an Environmental Inspector who will take the necessary action, in consultation with the Appropriate Government Authority, if required. Adhere to the measures outlined in the Wildlife Species of Concern Encounter and Discovery Contingency Plan (Appendix B).

Update for clarity, as there may be instances where consultation with the Appropriate Government Authority is not required. This does not affect any commitment made by Trans Mountain.

Volume 3 – Section 7.2 Snow Management Revised: Ensure that snow bladed off roads is not stockpiled at a height that prohibits proper visibility for drivers.

Update for redundancy. As snow will not be piled at a height that prohibits proper visibility for drivers, Measures related to the locations of gaps are in the following measure “Leave gaps in snow piles at obvious drainages, wildlife and trapping trails.” This does not change the meaning or affect any commitment made by Trans Mountain.

Volume 3 – Section 7.2 Snow Management Revised: Leave gaps in snow piles at obvious drainages, wildlife, livestock and trapping trails.

Update for clarity by adding the word “piles”. This does not change the meaning or affect any commitment made by Trans Mountain.

Volume 3 – Section 7.2 Topsoil Salvage Revised: Store all salvaged topsoil from the new permanent or temporary access road bed area in stockpiles along one or both edges of the access road or approved location in a manner that does not alter natural drainage patterns.

Update for consistency to ensure that salvaged topsoil can be stored at approved locations off the construction footprint to ensure that topsoil is stored properly, and does not alter natural drainage. This does not change the meaning or affect any commitment made by Trans Mountain.

Volume 3 – Section 7.2 Borrow Material Added the Activity/Concern “Borrow Material” Update for clarity by adding new heading for borrow material, as measures for borrow material were originally included under “Access Road Development”.

Volume 3 – Section 7.2 Borrow Material Moved: Source borrow material for access roads from nearby approved sites. Borrow material must be screened and approved by an Environmental Inspector prior to import. Added: Use geotextile, where practical, to conserve borrow materials during access road development.

TABLE 1 Cont’d

Section Sub-heading Update/Change Reason Volume 3 – Section 7.2 Road Ditches Revised activity/concern from ditches to road ditches. Update for clarity to as the section relates

only to road ditches. As the mitigation measures within this section are only applicable to road ditches, this does not change the meaning or affect any commitment made by Trans Mountain.

Volume 3 – Section 7.2 Road Ditches Revised: Ensure that ditches do not drain directly into a watercourse or wetland, unless limited by topography. Install drainage, erosion and sediment control measures (e.g., check dams), where required.

Update for clarity. The mitigation measure is re-focused to an objective-based measure by removing “and approved by the Appropriate Government Authority”. As roads will be constructed in accordance with Permit Conditions, this does not change the meaning or affect any commitment made by Trans Mountain.

Volume 3 – Section 7.2 Road Ditches Revised: Rock-line “V” ditches where required on steep grades or slopes, and on scraper or rounded “U” ditches, to reduce erosion and gullying.

Update for clarity by adding additional descriptions on the types of road ditches that may be rock-lined to steep grades and rounded “U” ditches. This does not change the meaning or affect any commitment made by Trans Mountain.

Volume 3 – Section 7.2 Access Road Use and Maintenance

Revised: Do not use de-icer or salt for access road maintenance. Restrict the use of sand within 10 m of watercourses, wetlands or lakes.

Update for redundancy and to focus on the objective of the measure by deleting “Prevent sand used for maintenance purposes from entering watercourses”. As mitigation measures are still included (Restrict the use of sand within 10 m of watercourses, wetlands or lakes), this does not change the meaning or affect any commitment made by Trans Mountain.

Volume 3 – Section 7.2 Access Road Reclamation

Revised: Avoid equipment access across watercourses once reclamation measures have been implemented unless approved equipment crossing installations are in-place.

Update for consistency with other Project documentation filed with the CER (e.g., Volume 6.0, Section 9.0 – Reclamation Management Plan [Filing ID A84124]). Reclamation is defined as the reconstruction of disturbed land/ ecosystem to an equivalent capability or state, where the expectation over time is that the reclaimed disturbance/ reconstructed ecosystem will be self-sustaining and will eventually replicate the existing terrain/ ecosystem over the long-term. Reclamation is a more accurate description of the activity, therefore, this does not change the meaning or affect any commitment made by Trans Mountain.

Volume 3 – Section 7.2 Access Road Reclamation

Revised the following bullet points: • remove cross drainage and excavate a shallow

ditch; • block off the access with the use of permanent

fences with locked gates, boulders, ditches, berms, rollback or other method suitable for the site;

• seed disturbed areas with an approved cover crop and/or grass/legume mix and install biodegradable erosion and sediment control measures, where warranted.

Update for consistency and add additional detail to all situations that may arise where these mitigation measures may be implemented. This does not result in a change of meaning or affect any commitment made by Trans Mountain, as it adds additional context for construction personnel to understand where these measures will be implemented.

Volume 3 – Section 7.3 Introduction Revised: The following mitigation measures will be implemented, where applicable, by Trans Mountain, its Contractors and Subcontractors during the clearing phase for facility construction.

• March 26 to August 16 (KP 968.58 to KP 1180.06, including Hope Relief Station, Sumas Pump Station, Sumas Tank Farm and Burnaby Terminal).

Update for redundancy. Migratory bird nesting periods are outlined in Appendix D of the Facilities EPP. As timing restrictions are still included as part of the Facilities EPP, this does not change the meaning or affect any commitment made by Trans Mountain.

Volume 3 – Section 7.3 Schedule Deleted: In the event that clearing or construction activities are scheduled to commence within the migratory bird nesting period, consult with a Wildlife Resource Specialist to determine the need to conduct a non-intrusive area search for evidence of nesting (e.g., presence of territorial males, alarm calls, distraction displays, adults carrying nesting material/food). Searches for evidence of nesting should occur within 7 days prior to the proposed activity. In the event there are extended periods of inactivity between construction activities during the migratory bird nesting period (i.e., a period greater than 7 days), consult with an Environmental Inspector regarding the potential need for follow-up searches for evidence of nesting.

Update for redundancy. Reference to migratory bird nesting protection in Section 6.0 is provided under the Wildlife heading on pages 6-2 to 6-3 and timing restrictions are included in Appendix D of the Facilities EPP. As timing restrictions are still included as part of the Project documentation, this does not change the meaning or affect any commitment made by Trans Mountain.

Volume 3 – Section 7.3 Clearing Limits Revised: Confine all clearing within the staked/flagged construction footprint boundaries. Clear vegetation from only those areas essential for construction. Adhere to clearing restrictions associated with environmental features and buffer areas in addition to those areas outlined in the RSMT (Appendix D).

Update for redundancy by removing “Do not clear, mow or grade beyond the stakes” as this is included in the statement “Confine all clearing/mowing within the staked/flagged construction footprint boundaries” within the same measure This does not change the meaning or affect any commitment made by Trans Mountain.

Volume 3 – Section 7.3 Clearing Limits Revised: Install interim drainage, erosion and sediment control measures (e.g., diversion ditches and berms, sediment fences) as soon as feasible following clearing to reduce the risk of erosion, as directed by an Environmental Inspector (Detail 1 and Detail 2 in Appendix C).

Update for consistency and add additional detail to all situations that may arise where these mitigation measures may be implemented. This does not result in a change of meaning or affect any commitment made by Trans Mountain, as it adds additional context for construction personnel to understand that these measures will be implemented to control drainage, erosion and sediment.

Section Sub-heading Update/Change Reason Volume 3 – Section 7.3 Forest Health

Measures- BC Revised: Dispose of timber infested with mountain pine beetle (or other forest parasite) by burning or mulching to eliminate the risk of spread of forest parasites. Burning is prohibited in the Lower Fraser Valley and Greater Vancouver areas from Wahleach Pump Station to Burnaby Terminal, and the Westridge Delivery lines, which includes Hope Pump Station, Sumas Tank Farm and Burnaby Terminal. Where root disease is present, infested stumps should be removed by push falling or extraction.


Volume 3 – Section 7.3 Slash Piling Revised: Leave an appropriate fuel break between slash piles based on risk and surrounding fuels.

Update for redundancy. An appropriate fuel break will be left between slash piles. This does not change the meaning or affect any commitment made by Trans Mountain.

Volume 3 – Section 7.3 Slash Disposal Revised: Burning is prohibited in the Lower Fraser Valley and Greater Vancouver areas from Wahleach Pump Station to Burnaby Terminal, and the Westridge Delivery lines, which includes Hope Pump Station, Sumas Tank Farm and Burnaby Terminal).


Volume 3 – Section 7.3 Slash Disposal Revised: Monitor weather forecast and ventilation index prior to burning. Schedule burning to limit the effects of smoke or consider alternative activities and disposal methods. Unless otherwise approved, do not burn slash debris within 100 m of neighbouring residences and business, or within 500 m of schools (when in session), hospitals and facilities used for continuing care. In consultation with an Environmental Inspector, consider weather conditions and prevailing winds before burning debris piles in the vicinity of highways, airports or roads.

Update for redundancy. Burning will be scheduled to limit the effects of smoke regardless of the vicinity to sensitive receptors. This does not change the meaning or affect any commitment made by Trans Mountain.

Volume 3 – Section 7.3 Slash Disposal Revised: Obtain and record the fire ratings daily to determine whether it is safe to burn. During slash disposal activities, maintain communication on a daily basis regarding burning activities.

Update for consistency. The mitigation measure is re-focused to an objective-based measure by removing the specific details of the communication requirements. As communication regarding burning activities is still required, this does not change the meaning or affect any commitment made by Trans Mountain.

Volume 3 – Section 7.3 Slash Disposal Revised: Monitor burning to prevent fire from spreading off-site. Extinguish burning embers before leaving the site and monitor burn sites to ensure that no smouldering debris remains. Push unburned stumps along the edge of the facility site after attempting to burn them.

Update for clarity and improve readability, as monitoring is conducted to prevent the fire from spreading. “at all times” is removed as redundant, as the mitigation measure requires personnel be on-site during burning activities. This does not change the meaning or affect any commitment made by Trans Mountain.

Volume 3 – Section 7.3 Slash Disposal Moved and revised: Confirm burn piles are entirely extinguished. Conduct infrared scanning of burn piles to confirm that hot spots do not exist.

Update for consistency to keep mitigation measures related to burning and slash disposal under one heading. Revised measure to include infrared scanning to ensure hot spots are not present. As this mitigation measure is still included in the Facilities EPP, this does not change the meaning or affect any commitment made by Trans Mountain.

Volume 3 – Section 8.0 Introduction Revised: The following mitigation measures will be implemented, where applicable by Trans Mountain, its Contractors and Subcontractors during topsoil handling and grading activities.




01-13283-GG-0000-EV-PLN-0013

TABLE 1 Cont’d

Section Sub-heading Update/Change Reason Volume 3 – Section 8.0 Environmental

Features Revised: Refer to mitigation measures provided under the Staking/Flagging/Fencing and Signage headings in subsection 7.1. In advance of topsoil handling, confirm the placement of stakes, flags and signage along the construction sites. Replace any stakes, flags and signage as required.

Update for clarity and improve readability, as the previous wording not clear on when the mitigation measure should be implemented. This does not change the meaning or affect any commitment made by Trans Mountain.

Volume 3 – Section 8.0 Signage Revised: Stake and label topsoil, transition and subsoil piles to assist in identification during reclamation activities. Measure moved from subsection 7.1.

Update for clarity by adding “to assist in identification during reclamation activities” to the measure. This does not change the meaning or affect any commitment made by Trans Mountain.

Volume 3 – Section 8.0 Soil Handling Contingency Measures

Revised: Implement the Soil Handling Contingency Plan (Appendix B) during topsoil salvage if any of the following are encountered: • little or no topsoil • poor colour separation between topsoil and

subsoils; • stony subsoils or topsoil; and • uneven boundary between topsoil and subsoil.

Update for consistency with the criteria that is included in the Soil Handling Contingency Plan. Mitigation measures for wind erosion are included in the Soil Erosion and Sediment Control Contingency Plan. Measures for shallow bedrock are applicable to pipeline activities. This does not change the meaning or affect any commitment made by Trans Mountain.

Volume 3 – Section 8.0 Soil Handling Contingency Measures

Revised: Implement the Wet/Thawed Soils Contingency Plan (Appendix B) during wet or thawed soil conditions when soils are too wet to support a particular construction activity. Soils will be considered to be excessively wet when the planned activity could cause damage to soils and result in a soil condition that would have a negative impact on reclamation activities. The decision to continue or suspend particular construction activities on lands with excessively wet/thawed soils will be made by the Construction Manager in consultation with an Environmental Inspector.

Update for clarity to ensure that activities are not permitted that would cause a negative impact on reclamation activities. The examples of rutting, compaction pulverization were not a comprehensive list of concerns, and the focus on reclamation allows for an end result to be measured rather than a narrow list of examples. This does not change the meaning or affect any commitment made by Trans Mountain.

Volume 3 – Section 8.0 Topsoil Salvage Depth

Revised: Salvage all available topsoil unless the material is unsuitable (e.g., bedrock, gravel, rock, disturbed land). Where soils are not readily distinguishable by colour, an Environmental Inspector and a Resource Specialist will provide direction based on an evaluation of soil texture and structure.

Update for consistency by removing specific depths for organic material. All topsoil will be salvaged, therefore this does not change the meaning or affect any commitment made by Trans Mountain.

Volume 3 – Section 8.0 Topsoil Salvage Depth

Deleted: Salvage very deep surface soils to a maximum depth of 40 cm, if encountered.

Update for consistency by removing specific depths for organic material. Topsoil salvage depths are outlined in the RSMT. This does not change the meaning or affect any commitment made by Trans Mountain.

Volume 3 – Section 8.0 Storage of Topsoil/Subsoil

Revised: Map and sign the locations of topsoil piles on as-built drawings to ensure that they can be easily located in the future to support reclamation efforts at the site.

Update for clarity to ensure that topsoil piles are signed as well as mapped to aid in identification. This does not change the meaning or affect any commitment made by Trans Mountain.

Volume 3 – Section 8.0 Erosion by Wind Revised activity/concern: from Wind Erosion to Erosion by Wind.

Update for clarity with the Project terminology. As the mitigation measures in this section relate to the erosion of soils by wind, this does not change the meaning or affect any commitment made by Trans Mountain.



01-13283-GG-0000-EV-PLN-0013

Page 22

TABLE 1 Cont’d

Section Sub-heading Update/Change Reason Volume 3 – Section 8.0 Erosion by Wind Revised: Tackify, apply water or snow, or pack the

topsoil stockpile if soils are showing signs of wind erosion (refer to the Soil Erosion and Sediment Control Contingency Plan in Appendix B).

Update for clarity, as mitigation measures will not be required for all soils that are prone to wind erosion, based on the site-specific conditions and season of construction. Contingency measures will be implemented in the event that soils are showing signs of erosion by wind. As this measure relates to the implementation of contingency measures, this does not change the meaning or affect any commitment made by Trans Mountain.

Volume 3 – Section 8.0 Erosion by Wind Revised: Vegetate the topsoil stockpiles and areas of vegetation disturbed during construction to stabilize topsoil and to reduce weed growth, where warranted.

Update for clarity, as not all topsoil piles will be vegetated to reduce weed growth. Mitigation measures will be implemented where warranted, to reduce weed growth. This does not change the meaning or affect any commitment made by Trans Mountain.

Volume 3 – Section 8.0 Dust Control Revised: If there is potential for landowners and/or occupants to be affected by dust emissions, consult with land agents to provide opportunity to report on issues and implement corrective actions, if warranted.

Update for clarity to improve wording of the mitigation measure by moving the statement “If there is potential for landowners and/or occupants to be affected by dust emissions” to the front of the mitigation measure. This does not change the meaning or affect any commitment made by Trans Mountain.

Volume 3 – Section 8.0 Grading Added: A separation layer (e.g., geotextile material, straw, hydromulch) will be required before placement of grade material onto undisturbed topsoil.

Update for clarity on the requirements of grade material storage on undisturbed topsoil. This does not change the meaning or affect any commitment made by Trans Mountain, as this mitigation measure serves to reduce the risk of admixing topsoil and grade spoil material.

Volume 3 – Section 8.0 Grading Revised: Keep the grade spoil stockpile separate from topsoil stockpile/berm. Maintain an adequate separation to avoid admixing between topsoil and grade subsoil stockpiles (Detail 4 in Appendix C).

Update for clarity and to re-focus on an objective-based mitigation measure. Adequate is defined in the Facilities EPP as “sufficient for a specific need or requirement. (e.g., in terms of soil separation, adequate separation is defined as no admixing of topsoil and subsoil)”. The intent of the mitigation measure is to prevent admixing of topsoil and subsoil. While no minimum separation distance is been provided, soil will be stored with a separation distance that does not result in admixing, therefore, this does not change the meaning or affect any commitment made by Trans Mountain and provides measures for Project.

Volume 3 – Section 8.0 Grading Added: Ensure that grade spoil does not mix with topsoil or foreign material (e.g., coarse woody debris).

Update for consistency with the mitigation measures in the Pipeline EPP (CER Condition 72) to ensure mitigation measures, procedures protocols and standards are consistent for all components of the Project. No mitigation measure was provided to ensure that grade spoil did not mix with CWD, therefore this serves to strengthen Project mitigation. This does not change the meaning or affect any commitment made by Trans Mountain and provides measures for Project.



01-13283-GG-0000-EV-PLN-0013

Page 23

TABLE 1 Cont’d

Section Sub-heading Update/Change Reason Volume 3 – Section 8.0 Grading Revised: Clearly identify grade spoil with signs or

staking. Update for clarity, as grade spoil piles will be labeled regardless of whether a colour change is obvious. As this serves to strengthen the measure, this does not change the meaning or affect any commitment made by Trans Mountain and provides measures for Project.

Volume 3 – Section 8.0 Drainage, Erosion, and Sediment Controls

Deleted: Install sediment fences near the base of cut slopes following grading (see Detail 1 provided in Appendix C of this EPP) . Inspect the temporary sediment control structures on a daily basis and repair, if warranted, before the end of each working day. Added: Install temporary drainage, erosion and sediment control structures following grading, where warranted. During construction, inspect these structures to ensure functionality and repairs will be completed as required (i.e., rain event).

Update for clarity and consistency. Measures throughout the Facilities EPP stated different inspection intervals for drainage, erosion and sediment control measures. Mitigation measures are now consistent to the interval and requirements for inspection of drainage, erosion and sediment control measures. This change does change the meaning of the mitigation measure and ensures that the inspection period for drainage, erosion and sediment control structures is clear. This does not affect any commitment made by Trans Mountain.

Volume 3 – Section 9.0 Introduction Revised: The following mitigation measures will be implemented, where applicable by Trans Mountain, its Contractors and Subcontractors during topsoil handling and grading activities. Environmental Facility Drawings have also been prepared (Appendix E) and should be reviewed prior to construction to review key issues that have been identified and mitigation measures that are to be implemented for each facility site.


Volume 3 – Section 9.0 Objectives Revised: avoid or reduce potential adverse effects associated with general facility construction activities.

Update for clarity by deleting “environmental” as the objectives are to avoid or reduce adverse effects. This does not affect any commitment made by Trans Mountain.

Volume 3 – Section 9.0 Hotline Exposure/Hydrovac

Added: Ensure hydrovac slurry that is suspected to be contaminated is stored and disposed of in accordance with applicable regulatory requirements.

Update for consistency with the mitigation measures in the Pipeline EPP (CER Condition 72) to ensure mitigation measures, procedures protocols and standards are consistent for all components of the Project. This measure was added to ensure that potentially contaminated slurry is handled appropriately, therefore this does not affect any commitment made by Trans Mountain.

TABLE 1 Cont’d

Section Sub-heading Update/Change Reason Volume 3 – Section 9.0 Blasting Added Activity/Concern and Measures for Blasting:

Blast competent bedrock encountered within required depth only if standard excavation methods are not feasible. If wildlife is spotted within the blasting area, use measures recommended by a Resource Specialist to displace wildlife prior to blasting. Utilize warning sirens, blasting mats, blasting controls and monitoring to reduce potential injury to wildlife and humans. Haul excavated trench spoil that is not suitable for use as backfill (e.g., excess bedrock) and dispose of at locations approved by an Environmental Inspector. Follow appropriate procedures provided in Guidelines for the Use of Explosives in or near Canadian Fisheries Waters (Wright and Hopky 1998) if blasting is necessary near watercourses. Monitor registered or known potable water wells located in close proximity of any blasting prior to and following blasting. This determination will be made based on site-specific conditions. Monitoring will include measurement of well yields, static and pumping water levels, as well as water sampling in accordance with Guidelines for Canadian Drinking Water Quality (Health Canada 2012).

Updated to include blasting measures should blasting occur at facility sites. Mitigation measures were previously included in Project documentation, and are not new for the TMEP. Any required blasting will be conducted in accordance with applicable permitting and regulatory requirements. This does not change the meaning or affect any commitment made by Trans Mountain.

Volume 3 – Section 9.0 Dewatering Revised: Assess the need for well points or other dewatering methods, prior to excavations, to intercept groundwater at site-specific locations.

Update for consistency with the mitigation measures in the Pipeline EPP (CER Condition 72) to ensure mitigation measures, procedures protocols and standards are consistent for all components of the Project.

Volume 3 – Section 9.0 Dewatering Revised: Delay excavations until immediately prior to construction works at locations with a high-water table or where the risk of sloughing is high.

Update for clarity to provide additional detail on when excavations will be delayed. This does not affect any commitment made by Trans Mountain.

Volume 3 – Section 9.0 Dewatering Revised: Place pumps onto an impermeable barrier (i.e., secondary containment trays). Pump grey water at least 50 m from the nearest watercourse, wetland or lake in a manner that does not cause erosion or any unfiltered or sediment-laden water to enter a waterbody. If, during pump-off, the pump-off water indirectly enters the watercourse or waterbody, pump-off activities will be suspended for re-assessment.

Update for clarity. The mitigation measure is re-focused to an objective-based measure by removing specific examples of areas where water can be discharged. This does not change the meaning or affect any commitment made by Trans Mountain, as the content of the mitigation measure has not changed and ensures discharge activities will be conducted in a manner that water does not enter a waterbody.

Volume 3 – Section 9.0 Dewatering Added: Install a diffusion device (e.g., sheet of plywood, wood pallet) to reduce the potential for erosion, and a sediment control device (e.g., filter bag) on the end of the discharge hose to contain any of the sediment that is suspended in the water. If a filter bag will be used, ensure that the filter bag is properly sized to match the pumping pressure.

Update for clarity. This update provides a mitigation measures to control erosion and sediment movement during trench dewatering. This does not change the meaning or affect any commitment made by Trans Mountain.

Volume 3 – Section 9.0 Dewatering Revised: Monitor the water discharge site to ensure that erosion, sediment loading, flooding or icing does not occur. Suspend dewatering and either apply erosion control measures, reduce the rate of discharge site or move the discharge site to a different location if it appears that the above effects could occur.

Update for clarity. The mitigation measure is re-focused to an objective-based measure. As the following mitigation measure in this section still includes the requirement for landowner/Appropriate Government Authority approval prior to pumping off the construction footprint, this does not change the meaning or affect any commitment made by Trans Mountain.



01-13283-GG-0000-EV-PLN-0013

Page 25

TABLE 1 Cont’d

Section Sub-heading Update/Change Reason Volume 3 – Section 9.0 Dewatering Moved: Ensure that landowner/Appropriate

Government Authority approval is in-place before pumping water off the construction footprint.

Update for clarity. Mitigation measure separated from the above measure to ensure that landowner or Appropriate Government Authority approval is obtained prior to pumping off water. As this requirement is still included in the Facilities EPP, this does not change the meaning or affect any commitment made by Trans Mountain.

Volume 3 – Section 9.0 Dewatering Added: All areas of sediment loading will be properly cleaned-up and the soil re-located back onto the Project Footprint.

Update for clarity as no mitigation measures related to sediment clean-up were provided in this section. This does not change the meaning or affect any commitment made by Trans Mountain, as this was added to ensure that areas of sediment loading are cleaned-up.

Volume 3 – Section 9.0 Dewatering Added: Adhere to the Contamination Discovery Contingency Plan (Appendix B) where water that has been potentially contaminated with hazardous materials is to be discharged to the environment. Prior to dewatering, a Contaminated Sites Resource Specialist will be contacted, and samples of the potentially contaminated material will be collected for testing, as warranted. Measures will be taken to contain the potentially contaminated water on-site and may include the use of tank trucks to haul contaminated water to a Trans Mountain-approved disposal facility and in accordance with the Waste Management Plan in Section 3.1 of Volume 6 of the Environmental Plans and the Spill Contingency Plan (Appendix B). Take steps to ensure the intake is submerged below the surface sheen and use sorbent booms to keep the sheen away from the pump intake.

Update for clarity on the procedures to be followed if contamination is suspected during trench dewatering activities. A Resource Specialist will be contacted, and samples will be taken where warranted. This does not change the meaning or affect any commitment made by Trans Mountain.

Volume 3 – Section 9.0 Drainage, Erosion and Sediment Controls

Added activity/concern: Drainage, Erosion and Sediment Controls.

Added to ensure mitigation measures to ensure drainage, erosion and sediment controls are installed and maintained. This does not change the meaning or affect any commitment made by Trans Mountain.

Volume 3 – Section 9.0 Drainage, Erosion and Sediment Controls

Added: Install temporary drainage, erosion and sediment control structures following grading, where warranted. During construction, inspect these structures to ensure functionality and repairs will be completed as required (i.e., rain event).

Added for clarity and consistency, as well as to re-focus to an objective-based mitigation measure. Measures throughout the Facilities EPP stated different inspection intervals for drainage, erosion and sediment control measures. Mitigation measures are now consistent to the interval and requirements for inspection of drainage, erosion and sediment control measures. This change does change the meaning of the mitigation measure and ensures that the inspection period for drainage, erosion and sediment control structures is clear. This does not affect any commitment made by Trans Mountain.

Volume 3 – Section 10.0 Introduction Added: The following mitigation measures will be implemented where applicable by Trans Mountain, its Contractors and Subcontractors during clean-up and reclamation..


Volume 3 – Section 10.0 Erosion Control Revised: Implement appropriate erosion control measures (e.g., soil compaction, soil covers, seeding, mulch and/or tackifiers) to stabilize soil berms, grade cuts, fills and other disturbed lands as warranted (Detail 2 in Appendix C).

Update for clarity by adding reference to Detail 2 in Appendix C of the Facilities EPP. As this Detail was previously included, this does not affect any commitment made by Trans Mountain.

Section Sub-heading Update/Change Reason Volume 3 – Section 10.0 Sediment Fences Added activity/concern: Sediment Fences

Added Mitigation Measures: Install temporary sediment fences, where warranted, to control sedimentation prior to final clean-up (Detail 1 in Appendix C).

Added for accuracy, and to ensure that sediment fences are installed prior to during clean-up and reclamation, where warranted. This does not affect any commitment made by Trans Mountain.

Volume 3 – Section 10.0 Topsoil Replacement

Revised: Replace topsoil evenly over disturbed land surfaces to pre-construction soil depths where reclamation will occur.

Added “to pre-construction depths” for clarity on the depth of topsoil to be reclaimed. This does not affect any commitment made by Trans Mountain.

Volume 3 – Section 10.0 Equipment/ Vehicle Travel

Revised: Limit approved equipment or vehicle access and passage over surfaces where topsoil has been replaced.

Update for clarity. Replaced “travel” with access and passage to ensure vehicle and equipment is restricted where topsoil has been replaced. This does not change the meaning or affect any commitment made by Trans Mountain.

Volume 3 – Section 10.0 Garbage and Debris Revised: Dispose of all remaining garbage and debris from the facility construction site at Trans Mountain-approved disposal locations.

Update for clarity and to focus on the disposal of garbage and debris, not just the removal from site. Garbage and debris will be disposed of at a Trans Mountain-approved facility, therefore, this does not change the meaning or affect any commitment made by Trans Mountain.

Volume 3 – Section 10.0 Burn Piles Deleted Activity/Concern: Burn Piles. Moved mitigation measure: Confirm that burn piles are properly extinguished on completion of construction to subsection 7.3.

Update for consistency to keep mitigation measures related to burning and slash disposal under one heading (Slash Disposal) on Page 7-7 in subsection 7.3. As this mitigation measure is still included in the Facilities EPP, this does not change the meaning or affect any commitment made by Trans Mountain.

Volume 3 – Section 11.0 Introduction Revised: The following mitigation measures will be implemented, where applicable by Trans Mountain, its Contractors and Subcontractors, during hydrostatic testing where water will be used to test pump station piping, terminal piping and tanks. Water will typically be withdrawn from collected on-site surface runoff, nearby watercourses or wetlands, or from an approved Municipal source, and hauled to the facility site in accordance with applicable permits and/or approvals. The Pressure Testing Program and the Hydrostatic Testing Plan will be filed with the CER pursuant to CER Conditions 112 and 113, respectively.


Volume 3 – Section 11.0 Workspace Deleted heading: Workspace Deleted mitigation measure: Refer to the MOC process (Section 2.7 of Volume 10 of the Environmental Plans) prior to taking additional workspace in the field.

Update for redundancy. As reference to ETWS are included in subsection 7.1 on Page 7-1, this does not change the meaning or affect any commitment made by Trans Mountain.

Volume 3 – Section 11.0 Water Sources Deleted: Complete the Water Withdrawal and Discharge Form in the Water Withdrawal and Discharge Procedures Management Plan for each water withdrawal and discharge site.

Update for redundancy, as the Water Withdrawal and Discharge form does not apply to the facilities. This does not affect any commitment made by Trans Mountain.

Volume 3 – Section 11.0 Sump Excavation Deleted: Avoid excavation of sumps for use in withdrawing water, unless approved by the Environmental Inspector. Added: Ensure that the excavation of sumps for use in withdrawing water are approved by the Environmental Inspector.

Update for consistency with the mitigation measures in the Pipeline EPP (CER Condition 72) to ensure mitigation measures, procedures protocols and standards are consistent for all components of the Project. Intent of the mitigation measure did not change, therefore this does not change the meaning or affect any commitment made by Trans Mountain.

TABLE 1 Cont’d

Section Sub-heading Update/Change Reason Volume 3 – Section 11.0 Isolate Pumps Revised: Isolate test pumps, generators and fuel

storage tanks with secondary containment to capture and retain any spills/leaks of fuels or lubricants.

Update for clarity. Mitigation measure is re-focused to an objective-based measure by deleting specific examples and replacing with “secondary containment”. This does not change the meaning or affect any commitment made by Trans Mountain, as the requirements for secondary containment are still included.

Volume 3 – Section 11.0 Withdrawal Moved: Ensure the applicable approvals (i.e., TDL in Alberta or Section 10 [Short-Term Use of Water] in BC) are in-place prior to withdrawing water for hydrostatic testing. Adhere to Conditions outlined in applicable permits. Permitted volumes and flow rates for water withdrawal must be followed.

Updated for consistency. Moved all approval related measures to the “Approvals, Licences and Permits” heading in this section. This does not change the meaning or affect any commitment made by Trans Mountain.

Volume 3 – Section 11.0 Withdrawal Deleted: In BC, withdrawal rate and volume will generally not be permitted to exceed 5% on small streams, 10% on medium streams and 15% of large streams unless otherwise approved by the appropriate authority. These values will vary with fisheries sensitivity. In Alberta, withdrawal rate and volume will generally not exceed 10% of the flow rate of the watercourse or of the volume of the body of water unless otherwise approved by the appropriate authority. Avoid or reduce disturbance of the streambed when installing pump intakes.

Update for redundancy by deleting general requirements. As Trans Mountain will abide by Permit Conditions, this does not change the meaning or affect any commitment made by Trans Mountain.

Volume 3 – Section 11.0 Dewatering Deleted: Conduct testing of the test water and soils at the discharge site in accordance with applicable Federal and Provincial requirements.

Update for redundancy. This measure is duplicated above under the heading Sampling on Page 11-1 “Conduct sampling and testing of the sites (e.g., soils, water) receiving test water, if warranted, to abide by requirements related to test water discharge and any other application/approval requirements.”. As the measure is still included in the Facilities EPP, this does not change the meaning or affect any commitment made by Trans Mountain.

Volume 3 – Section 11.0 Dewatering Deleted: Dewater into a bar ditch, if feasible, or onto non-arable land. Do not water onto cultivated lands or directly back into a watercourse, wetland or lake unless otherwise allowed by water discharge approvals.

General update to align with standard pipeline construction practices. This does not change the meaning or affect any commitment made by Trans Mountain.

Volume 3 – Section 11.0 Dewatering Added: Ensure water discharge is conducted in accordance with required discharge approvals. Unless otherwise approved, do not dewater directly or indirectly back into a watercourse, wetland or lake.

Update for clarity on approved locations of water discharge. Withdrawal and discharge will align with CER Conditions 112 and 113, therefore, this does not change the meaning or affect any commitment made by Trans Mountain.

Volume 3 – Section 11.0 Sample Collection Revised: Collect samples of source water, hydrostatic test water and soil of the receiving environment prior to discharge to land or water and analyze according to the parameters listed in Water Withdrawal and Discharge Procedures Management Plan (Section 8.6 of Volume 6 of the Environmental Plans).

Update for clarity by adding “to land or water” to ensure that samples are collected for all discharge locations. This does not change the meaning or affect any commitment made by Trans Mountain.

Volume 3 – Section 11.0 Daylighting Deleted: Activity/Concern: Daylighting Deleted: Follow applicable EPP protection measures if exposure (daylighting) of below grade sections of facility piping is necessary for inspection or repairs.

Update for redundancy as daylighting is not a measure related to hydrostatic testing. Mitigation measures for hydrovac are included in Section 9.0 on Page 9-1 under the heading Hotline Exposure/Hydrovac, therefore, this does not change the meaning or affect any commitment made by Trans Mountain.

Volume 3 – Section 12.0 References Reviewed, checked and updated reference sources and links.

Update to reference materials used to inform the Facilities EPP. This does not change the meaning or affect any commitment made by Trans Mountain.

In accordance with the Contamination Identification and Assessment Plan, a Contaminated Resource Specialist will ensure the appropriate response and mitigation is carried out during construction in the identified high-risk areas. When working in areas of moderate- or high-risk, workers shall be informed of the potential to encounter contamination. In the event unexpected contamination is encountered, this Contamination Discovery Contingency Plan will be initiated

Update for clarity as response to CER IR 20.6. As this measure was revised in response to a CER IR, this does not change the meaning or affect any commitment made by Trans Mountain.

Volume 3 – Appendix B Section 1.1 Asbestos

Added new heading “Asbestos”. All Asbestos language and mitigations moved under one section.

Update for consistency and to keep mitigation measures related to asbestos under one heading. As these mitigation measures are still included in the Facilities EPP, this does not change the meaning or affect any commitment made by Trans Mountain.


Revised: Visual field indicators to identify asbestos or asbestos-containing material (ACM) (>1% by weight of asbestos fibres and powder/dust or friable) include: serpentine rock, fibrous appearance, greasy lustre; brake pads, cement piping, vinyl tiles, home insulation, cement siding); and for asbestos deposit areas: former landfills, asbestos dumps including other signs of waste deposition (e.g., fill, liners, surficial evidence). The microPHAZIR™, by ThermoFisher Scientific, is the tool for field screening for asbestos or ACMs when excavation during construction is performed where asbestos or ACMs are suspected.

Revised in response to CER IR 34.1 Classification and Disposal of Asbestos Contamination.


Deleted: The field screening will be visual observation for asbestos (e.g., serpentine rock, fibrous appearance, greasy lustre) supported by microPHAZIR™.

Update for redundancy with the changes made to the statement above in response to IR 34.1. The description of asbestos is included in the revised statement, therefore this does not change the meaning or affect any commitment made by Trans Mountain.

TABLE 1 Cont’d

Section Sub-heading Update/Change Reason Volume 3 – Appendix D Sumas Terminal Added:

In the event amphibian (i.e., long-toed salamander, northern red-legged frog, Pacific tree frog, western toad) or small mammal (i.e., Olympic shrew, Pacific water shrew, Trowbridge’s shrew) are encountered in the work area a salvage may be necessary. Consult with an Environmental Inspector to determine the need for a salvage. Any relocation of wildlife will be conducted by a Wildlife Resource Specialist and salvages will comply with Permit Conditions.

Update to Project. Field work has been conducted at the Sumas Terminal, and updates are reflected in the RSMT. Information reflects the most current construction plans at Sumas Terminal.

Volume 3 – Appendix D Sumas Terminal Added: During site assessments on March 6, 2018 and March 4, 2019 the forest to the north, east, and west of the existing facility was determined to be the rare ecological community Western redcedar – foamflower (Thuja plicata - Tiarella trifoliata, S2S3, Blue-listed). The forest to the south was determined to be the rare ecological community western redcedar – Sitka spruce/skunk cabbage (Thuja plicata – Picea sitchensis / Lysichiton americanus, S3?, Blue-listed). The 10-15 m of dense Himalayan blackberry around the existing fence line are not part of these rare ecological communities. No mitigation is recommended for these Blue-listed ecological communities because cleared areas will not be reclaimed following construction. All clearing around the existing terminal is located within an Early Draft Critical Habitat polygon for Roell’s brotherella moss (Environment Canada 2014). The extent of Early Draft Critical Habitat is not publicly available and is provided with the permission of Environment and Climate Change Canada. The forested areas within 30 m of watercourses are considered locations of interest that possesses the ecological attributes required for Roell’s brotherella moss. Within these areas, a Resource Specialist should screen for Roell’s brotherella moss pre-disturbance. If Roell’s brotherella moss is located on the workspace, re-locate its substrate to a suitable habitat in the immediate vicinity of the Project. The location (e.g., aspect and vertical position) and habitat (e.g., substrate, light and humidity conditions) of the receiving sites will emulate conditions, including the substrate types that occurred in the critical function zone at the transplant source location, to the extent feasible. Japanese knotweed and wild chervil are known to occur at the Sumas Terminal. Himalayan blackberry occurs around the existing fence line.

Update Project information. Field work has been conducted at the Sumas Terminal, and the footprint has changed. Information reflects the most current construction plans at Sumas Terminal. Vegetation features may be impacted by construction activities. As this is added to ensure protection of features, this does not change the meaning or affect any commitment made by Trans Mountain.

Volume 3 – Appendix D Sumas Terminal Added: A portion of a needle-leaf treed swamp (Sumas_WT_1) within the south portion of the expansion area may potentially be permanently disturbed by construction activities. Ensure approvals under Section 11 of the Water Sustainability Act are in place prior to construction, as required. Comply with all approval Conditions. A needle-leaf treed swamp (Sumas_WT_2) is located adjacent to the expansion area, however the wetland will not be directly disturbed.

Update Project information. Field work has been conducted at the Sumas Terminal, and the footprint has changed. Information reflects the most current construction plans at Sumas Terminal. Wetland may be impacted by construction activities. As this is added to ensure protection of wetlands and waterbodies, this does not change the meaning or affect any commitment made by Trans Mountain.

Volume 3 – Appendix D Sumas Terminal Revised: There is an artificial pond (WT-1606) located at the east side of the pump station that may be directly or indirectly affected by construction activities.

Indigenous Group Engagement

Added: Trans Mountain prepared the Heritage Resources and Sacred and Cultural Sites Plan to satisfy CER Condition 100 (Filing ID A6Y0U2) which provides a list of sacred and cultural sites identified within 1 km of the Project, including access roads and temporary construction lands and infrastructure sites. Site-specific information outside of 1 km was considered, however, as the EPP addresses resources on the Project Footprint, no specific mitigation was or could be employed for sites well outside of the disturbance area. Appendix 8 of the CER reconsideration of aspects of its OH-001-2014 Report as directed by Order in Council P.C. 2018-1177 MH-052-2018 (Filing ID A6S2D8) identifies the sources of information provided by Indigenous intervenors and commenters in the OH-001-2014 hearing, and Indigenous intervenors in the MH-052-2018 hearing. This information, along with information contained in the outcomes of Phase III Crown consultation, the permitting process and consultation logs were reviewed to understand specific interactions between sacred and cultural sites and the Project. Information shared by Indigenous groups during Phase III Crown consultation about sacred and cultural sites already addressed in the OH-001-2014 proceeding or in Condition 97 were not included in the Condition 100 update. Sacred and cultural sites identified in the OH-001-2014 proceeding, MH-052-2018 Reconsideration proceeding, or Phase III Crown consultations, and not already captured under Condition 97 are outlined in Condition 100 (Filing ID A6Y0U2). Some Indigenous groups provided Trans Mountain sacred and cultural site information confidentially. These sites are not included in Condition 100. Confidential information has been received from Asini Wachi Nehiyawak (Mountain Cree Traditional Band), Coldwater Indian Band, Ditidaht First Nation, Foothills Ojibway First Nation, Kwikwetlem First Nation, Maa-Nulth Treaty Society, Nicomen Indian Band, Nooaitch Indian Band, Shackan Indian Band, Simpcw First Nation, Squamish Nation, Stk’emlupsemc te Secwepemc of the Secwepemc Nation and Tsleil-Waututh Nation. Trans Mountain will work with Indigenous groups to mitigate confidential Traditional Land Use (TLU) sites and implement recommended mitigation, where practicable, using the process outlined in Condition 100. Indigenous engagement is ongoing and new information will be incorporated into construction planning.

Updated for clarity. Further information is included to provide context to the continuing Indigenous engagement being conducted. This does not change the meaning or affect any commitment made by Trans Mountain.

1.0 INTRODUCTION Trans Mountain Pipeline ULC’s (Trans Mountain’s) Facilities Environmental Protection Plan (Facilities EPP) was approved by the Canada Energy Regulator (CER) (formerly the National Energy Board [NEB]) on December 5, 2017 (Filing ID A88418). This updated Facilities EPP has been prepared to provide additional clarity for effective implementation during construction.

The mitigation measures and procedures outlined in this Facilities EPP are reviewed and updated, when required, as design updates occur on the Trans Mountain Expansion Project (TMEP or the Project).

1.1 Project Description

Following the Federal Court of Appeal (FCA) Decision on 30 August 2018, the Certificate of Public Convenience and Necessity (CPCN) authorizing construction of the Project was declared null and void. Construction ceased and the Project was put into a state of safe shut-down, pending next steps. The CER has conducted a Reconsideration Process (MH-052-2108) since that time to address faults found by the FCA in its disposition of marine-traffic related matters, and the Federal government has conducted a Phase III Consultation process with affected Indigenous groups.

On June 18, 2019, the Governor General-in-Council, on the recommendation of the Minister of Natural Resources, directed the CER to issue CPCN OC-065, and various Amending Orders, to Trans Mountain to permit the Project to proceed, subject to 156 Conditions. As a result of the decision of the Federal Cabinet and the issuance of a CPCN by the CER on June 21, 2019, Trans Mountain has resumed construction of the Project.

The Facilities EPP was submitted to Appropriate Government Authorities, potentially affected Indigenous groups and affected landowners/tenants on November 17, 2016 for review. Feedback was requested by February 17, 2017, although additional feedback was considered up until March 2017. Trans Mountain incorporated any feedback into the Facilities EPP or has provided rationale for why input has not been included, as summarized in Appendix F.

1.2 Purpose

The purpose of the Facilities EPP is to communicate environmental procedures and mitigation measures to construction and inspection personnel in a clear, concise format. These potential mitigation measures will be implemented, where applicable, during construction of the facilities to avoid, mitigate or reduce potential adverse environmental effects.

Specifically, the Facilities EPP:

• identifies mitigation measures to be implemented during construction of the facilities;

• provides instructions for carrying out construction activities in a manner that will avoid or reduce adverse environmental effects; and

• serves as reference information to support decision-making and provides direction to more detailed information (i.e., resource-specific mitigation, management and contingency plans).

This updated Facilities EPP is intended to be a comprehensive compilation of all environmental protection procedures, mitigation measures and monitoring commitments, as set out in Trans Mountain’s Application, its subsequent filings or as otherwise committed to during the CER proceedings.

Trans Mountain confirms its intention to implement all of its commitments pursuant to CER Conditions 2 and 6.

1.3 Traditional Ecological Knowledge and Traditional Land Use

Indigenous Traditional Knowledge (ITK) is typically documented to preserve historical and familial connections, territorial occupation, land and resource use and temporal execution strategies. ITK includes but is not limited to the collection of Traditional Ecological Knowledge (TEK) during biophysical field survey participation for the Project and Traditional Land Use (TLU) study information from potentially affected Indigenous groups. Preliminary background ITK data was compiled for the Application and was consulted during the development of the CER Condition Plans, which helped determine the mitigation measures included in the Facilities EPP. The following sources were used:

• publicly available ITK, TEK and TLU reports;

• open houses and community gatherings;

• meetings and conversations with Indigenous group representatives;

• public record of comparable past projects or previous environmental assessments;

• published reports from Appropriate Government Authorities involved in administering or regulating a specified area or resource (e.g., integrated resource plans, land and resource management plans); and

• Geographic Information System (GIS) tools to determine spatial relationships of source data to the Project.

TEK was collected during biophysical field surveys conducted for the Project. Trans Mountain has reviewed information provided in TLU reports from participating Indigenous groups and traditional knowledge. Trans Mountain will continue to take available and applicable Indigenous TLU and TEK into consideration in updating the Facilities EPP and other CER Condition Plans, as necessary. TEK and TLU information collected and made available is provided in the relevant CER Condition Plans (e.g., Condition 97).

Other relevant information on sacred and cultural sites, arising from Phase III Consultation, has been incorporated into an updated filing of Condition 100 – Heritage Resources and Sacred and Cultural Sites Plan (Filing ID C01853). The Facilities EPP has been updated to include sacred and cultural sites identified in the Condition 100 filing, where relevant.

2.0 ENVIRONMENTAL PROTECTION PLAN ORGANIZATION This section provides an overview of the organization and scope of the Facilities EPP.

2.1 Organization

The Facilities EPP identifies the mitigation measures that will be implemented, where applicable, during pre-construction, construction and post-construction activities associated with Project facility development. Contingency Plans (Appendix B) are provided to address unforeseen events or conditions that may arise during these activities. Management Plans (Volume 6 of the Environmental Plans) describe the specific environmental management procedures and mitigation measures that build on the Facilities EPP and may apply to ongoing construction activities. To facilitate construction, the mitigation measures from these plans have been consolidated in Appendix G of the Pipeline EPP (Volume 2 of the Environmental Plans).

Environmental mitigation measures are identified under the heading "Measures" by "Activity/Concern" in accordance with the progression of construction activities, and are intended to be read in conjunction with the Resource-Specific Mitigation Table (RSMT) (Appendix D) and the Environmental Facility Drawings (Appendix E) that identify known environmental resources and potential issues as well as specific locations where the implementation of mitigation measures may be warranted during construction. Locations of facility sites are referred to by KPs.

The Facilities EPP provides:

• an understanding of the general environmental and socio-economic background of the construction activities planned for the facility sites;

• the extent and limitations of the Facilities EPP;

• information to identify specific or unique mitigation measures to be implemented to address environmental and socio-economic issues associated with facility construction; and

• general mitigation measures or industry-accepted standards and procedures that are typically applied during a construction project are also provided. These measures are generally provided in accordance with the sequence of construction or grouped by Project component.

This Facilities EPP is organized as follows:

• Section 1.0 Introduction provides an introduction to, and description of, the Project, outlines the purpose of the Facilities EPP and provides an overview of roles and responsibilities.

• Section 2.0 Environmental Protection Plan (EPP) Organization provides details regarding the layout and general scope and limitations of the Facilities EPP.

• Section 3.0 Consultation and Engagement provides details on the program conducted for the Project in relation to the Facilities EPP, pursuant to CER Condition 78.

• Section 4.0 Environmental Compliance provides an overview of tools, decision-making processes, plans and documentation to facilitate compliance with environmental legislation, regulatory approvals, permits, commitments and the specific requirements set forth in the Facilities EPP.

• Section 5.0 Notifications and Permitting provides details pertaining to specific activities to be followed, to ensure Appropriate Government Authorities, potentially affected Indigenous groups, landowners/tenants and applicable interested parties are properly notified prior to commencing facility construction activities or, as warranted, during the construction period.

• Section 6.0 General Measures provides an overview of the general measures that may be implemented during any or all of the construction phases of the facilities.

4.0 ENVIRONMENTAL COMPLIANCE Environmental compliance is facilitated through sharing of information, providing orientations/training, retaining Qualified Personnel and providing on-site inspection of activities through a proactive and adaptive inspection program.

Trans Mountain has developed an Environmental Compliance Management Plan (ECMP) to support construction execution and ensure full compliance with applicable legal requirements, regulations, permits, approval Conditions and commitments made by Trans Mountain. In addition, an Environmental and Compliance Education Training Program has been designed to ensure that all Project personnel are trained and aware of roles and responsibilities. The Organizational Structure (previously found in subsection 4.3 of this Facilities EPP) is now being prepared for CER Condition 88.

Trans Mountain established the Integrated Safety and Loss Management System (ISLMS) pursuant to Section 6 of the 2020 Canadian Energy Regulator Onshore Pipeline Regulation (CER OPR). The ISLMS applies to Company activities including the design, construction and operation of a pipeline and facilities. The ISLMS outlines Trans Mountain’s commitment to establishing, implementing and monitoring processes and controls to ensure that it is conducting business in a safe, environmentally responsible and sustainable manner. Information on the ISLMS was previously found in subsection 4.2 of this Facilities EPP, and has been re-located to the ECMP.

During the course of construction, it may be necessary to modify or create new procedures to address site conditions not previously identified in the Facilities EPP. Field-based decision-making and Project-approved contingency plans will be implemented to address unexpected conditions as described in Field Level Environmental Change Management section of the ECMP.

4.1 Potential Permits, Approvals and Authorizations

Trans Mountain will work with the Appropriate Government Authorities to obtain the necessary environmental permits, approvals and authorizations prior to the commencement of applicable construction activities. Applicable Federal and Provincial permits, approvals and authorizations are provided in Tables 4-1 and 4-2, respectively.

Trans Mountain will work with Municipalities to provide filing demonstration of conformance applicable to the Project prior to the commencement of construction. While these tables are comprehensive, they are not exhaustive and additional permits may be required. Permits, approvals and authorizations will be available throughout the construction and commissioning phases of the Project through the Permit Binder.

6.0 GENERAL MEASURES Introduction This section describes the mitigation measures that will be implemented, where applicable, by Trans Mountain, its Contractors and Subcontractors prior to the commencement of construction activities and will be followed for each phase of facility construction to ensure protection of environmental features, as well as delineation of facility boundaries.

Objective The objective of the following mitigation measures is to avoid or reduce potential adverse environmental effects associated with general facility construction activities. Construction will be completed in a manner that avoids or reduces adverse effects on residents in the area, nearby land users and socio-economic and environmental features.

Refer to the Socio-Economic Management Plan (within CER Condition 72) for broad mitigation measures related to socio-economic effects and reference to Plans that contain more specific mitigation on socio-economic matters. Refer to the Socio-Economic Effects Monitoring Plan prepared for CER Condition 13 for the monitoring approach and Project-specific indicators related to select socio-economic effects. Contractor requirements pertaining to worker accommodation during construction and further details on the worker code of conduct can be found in the Worker Accommodation Strategy prepared for CER Condition 59. These plans are contained in Section 2.0 of Volume 6 of the Environmental Plans.


Review Mitigation Measures for Environmental Features

1. The Environmental Inspector will review mitigation measures to be implemented during construction to avoid or reduce effects on environmental features (i.e., rare plants and rare ecological communities, wildlife species at risk, archaeological features, TLU sites and other sensitive or cultural features) on or in proximity to the facility site. This review will be conducted in advance of construction at locations where any of the above features are known to be present to ensure that suitable and appropriate procedures have been selected and can be implemented prior to construction, where applicable.

2. An Environmental Inspector is responsible for monitoring compliance with environmental and socio-economic commitments, undertakings and Conditions of permits and approvals, as well as applicable environmental legislation, Trans Mountain’s policies, procedures, and industry-accepted standards. An Environmental Inspector may designate responsibility for environmental and socio-economic compliance monitoring in certain cases based on the nature of the activity and the availability of appropriate alternative personnel (e.g., Activity Inspector) (refer to the ECMP in Volume 10 of the Environmental Plans).

3. An Environmental Inspector will organize on-site meetings in consultation with the Construction Manager or designate and, as the need arises, to address resource-specific issues, as well as review construction methodologies (refer to the ECMP in Volume 10 of the Environmental Plans).

4. An Environmental Inspector will review, collect, organize and disseminate all environmentally-related information and documentation that arises during construction, and will be responsible for the preparation of daily Environmental Inspection reports (refer to the ECMP in Volume 10 of the Environmental Plans).

Page 6-2


Review Mitigation Measures for Environmental Features (cont’d)

5. Environmental information (e.g., erosion concerns or natural drainage patterns) will be collected throughout construction for documentation and the assessment of effectiveness of procedures/measures used to aid or inform the decision-making process during post-construction (refer to the ECMP in Volume 10 of the Environmental Plans).

6. The Environmental Inspector will document construction methods, decisions related to implementation and location of mitigation measures and final reclamation measures and issues encountered, as well as communication records for discussions with Appropriate Government Authorities.

7. Refer to the RSMT (Appendix D) and the Environmental Facility Drawings (Appendix E).

Species at Risk 8. Ensure that mitigation measures concerning wildlife and plant species at risk are communicated to construction personnel and supported by an Environmental Inspector. Refer to information on species at risk presented in the RSMT in Appendix D and the Environmental Facility Drawings in Appendix E for locations of, and mitigation measures for wildlife and vegetation species at risk or their habitats.

9. Suspend specific activities if previously unidentified species at risk are encountered on the work site during construction. Implement the following plans as appropriate: a. Rare Ecological Communities or Rare Plant Species of Concern

Discovery Contingency Plan (Appendix B); b. Wildlife Species of Concern Encounter and Discovery Contingency Plan

(Appendix B); and c. Wildlife Conflict Management Plan (Section 6.5 of Volume 6 of the

Environmental Plans).

10. Report observations of species at risk immediately to an Environmental Inspector. Environmental Inspector will record the location in the daily reports and locate and mark sightings for future reference in Post-Construction Environmental Monitoring documentation.

Wildlife 11. Where feasible, initiate or complete clearing and construction activities outside of the migratory bird nesting period, where feasible, to reduce the risk of encountering migratory birds nesting on the facility site (Environment Canada 2018).

12. Clear or mow areas of vegetation (in particular, trees, grasslands, pasture) outside of the migratory bird nesting period to reduce the potential of nesting birds where work is scheduled to occur during the migratory bird nesting period.

13. In the event clearing or construction activities are scheduled to commence within the migratory bird nesting period, consult with an Environmental Inspector or Wildlife Resource Specialist to determine the need to conduct a non-intrusive area search for evidence of nesting (e.g., presence of territorial males, alarm calls, distraction displays, adults carrying nesting material/food). Searches for evidence of nesting should occur within 7 days prior to the proposed activity. In the event there are extended periods of inactivity between construction activities during the migratory bird nesting period (i.e., a period greater than 7 days), consult with an Environmental Inspector regarding the potential need for follow-up searches for evidence of nesting.


01-13283-GG-0000-CHE-RPT-0027

Page 6-3


Wildlife (cont’d) 14. In the event an active nest is found, the nest will be subject to site-specific mitigation measures (e.g., clearly marked species-specific buffer around the nest or non-intrusive monitoring). The appropriate mitigation measures will be selected by an Environmental Inspector, in consultation with a Wildlife Resource Specialist (refer to the Wildlife Species of Concern Encounter and Discovery Contingency Plan in Appendix B).

15. Existing riparian vegetation immediately surrounding artificial ponds will be allowed to remain during and post-construction to provide terrestrial habitat for amphibians. Remove temporary exclusion fencing once it is no longer needed. Prior to Project clearing and construction, an amphibian survey and salvage will be conducted to ensure that any amphibians within the Burnaby Terminal property will not be harmed by Project activity. A Qualified Professional (i.e., Wildlife Resource Specialist) will be on-site to conduct an amphibian survey and relocate amphibians out of the active work site. This work will be done in a manner consistent with the Provincial amphibian salvage permit and Best Management Practices for Amphibian and Reptile Salvages in British Columbia (BC MFLNRO 2016).

16. In the event that active barn swallow nests are found during Project activity, the appropriate mitigation will be selected by an Environmental Inspector in consultation with a Wildlife Resource Specialist (e.g., species-specific buffer or non-intrusive monitoring).

17. Implement the Wildlife Species of Concern Encounter and Discovery Contingency Plan (Appendix B) in the event of an encounter with wildlife during construction, either at the construction site or on the commute to or from the construction site. Report any incidents or collisions with wildlife to Environmental Inspector who will consult with the Appropriate Government Authorities and the local conservation officer, if applicable (Wildlife Conflict Management Plan in Section 6.5 of Volume 6 of the Environmental Plans). Follow the incident reporting processes outlined in the Project Emergency Response Plan (ERP) (CER Condition 89) for safety-related incidents.

18. Implement the measures in the Wildlife Conflict Management Plan to prevent human/wildlife conflict and wildlife mortality (Section 6.5 of Volume 6 of the Environmental Plans).

19. Construct the facility in a well-organized and efficient manner to limit the duration of sensory disturbance to wildlife.

20. Do not harass or feed wildlife. Do not store food in areas readily accessible to wildlife.

21. Prohibit all Project personnel from having pets on facility sites.

22. All Project workers are strictly prohibited from hunting, fishing, trapping and gathering plants within or along the construction footprint and at any other construction sites including but not limited to Trans Mountain facilities and premises.

23.

Topsoil Salvage 10. Salvage topsoil at access roads where grading, bar ditches, fill or other materials are necessary.

11. Store all salvaged topsoil from the new permanent or temporary access road bed area in stockpiles along one or both edges of the access road or approved location in a manner that does not alter natural drainage patterns.

12. Implement appropriate weed control and erosion and sediment control measures on topsoil stockpiles (refer to the Weed and Vegetation Management Plan provided in Section 5.5 of Volume 6 of the Environmental Plans).

Access Road Development

13. Ensure that approaches to highway and secondary roads are constructed and signed in accordance with the requirements and/or codes of the local road authority.

Borrow Material 14. Source borrow material for access roads from nearby approved sites. Borrow material must be screened and approved by an Environmental Inspector prior to import.

15. Use geotextile, where practical, to conserve borrow materials during access road development.

Drainage, Erosion and Sediment Control

16. Install culverts, drainage and erosion control measures in accordance to the construction drawings and details (Detail 3 in Appendix C).

Road Ditches 17. Ensure that ditches do not drain directly into a watercourse or wetland, unless limited by topography. Install drainage, erosion and sediment control measures (e.g., check dams), where required.

18. Rock-line “V” ditches where required on steep grades or slopes, and on scraper or rounded “U” ditches, to reduce erosion and gullying.

19. Adhere to the Canadian Association of Petroleum Producers Environmental Operating Practices for the Upstream Petroleum Industry for British Columbia – Geophysics (CAPP 2001) and the Field Guide for Erosion and Sediment Control (Government of Alberta 2011) for recommended spacing gaps in berm installation to direct water to ditches.

Access Road Use and Maintenance

20. Do not use de-icer or salt for access road maintenance. Restrict the use of sand within 10 m of watercourses, wetlands or lakes.

21. Apply only water or non-toxic and non-persistent chemical products approved by an Environmental Inspector to access roads for dust control at parking locations or in the vicinity of resource-specific features.

22. Do not apply dust control suppressants to roads during windy conditions or within 300 m of a watercourse or wetland. Dust control chemicals are to be approved by an Environmental Inspector, or designate, in advance of application. The use of oil for dust control on roads during maintenance activities is prohibited.

23. Maintain all side cuts in roads in a stabilized and re-vegetated condition, to the extent feasible. Apply geotechnical or bioengineering techniques, where warranted, to control chronic slumping problems that have the potential to contribute sediment to nearby watercourses/wetlands.

21. Obtain the necessary burning permits prior to disposal and conduct burning in accordance with burning permit requirements and applicable regulations (Sections 4.0 and 5.0 for applicable permits and regulations).

22. Burning is prohibited in the Lower Fraser Valley and Greater Vancouver areas from Wahleach Pump Station to Burnaby Terminal, and the Westridge Delivery lines, which includes Hope Pump Station, Sumas Tank Farm and Burnaby Terminal).

23. Monitor weather forecast and ventilation index prior to burning. Schedule burning to limit the effects of smoke or consider alternative activities and disposal methods. Unless otherwise approved, do not burn slash debris within 100 m of neighbouring residences and business, or within 500 m of schools (when in session), hospitals and facilities used for continuing care. In consultation with an Environmental Inspector, consider weather conditions and prevailing winds before burning debris piles in the vicinity of highways, airports or roads.

24. Obtain and record the fire ratings daily to determine whether it is safe to burn. During slash disposal activities, maintain communication on a daily basis regarding burning activities.

25. Pile slash in a manner that allows for clean, efficient burning of all material. Implement techniques to limit smoke production including limiting pile size, reducing fuel moisture content and maintaining loose burning piles free of soil.

26. Ensure that slash burning crews have firefighting equipment on hand that is capable of controlling any fire that may occur as a result of their activities.

27. Monitor burning to prevent fire from spreading off-site. Extinguish burning embers before leaving the site and monitor burn sites to ensure that no smouldering debris remains. Push unburned stumps along the edge of the facility site after attempting to burn them.

28. Confirm burn piles are entirely extinguished. Conduct infrared scanning of burn piles to confirm that hot spots do not exist.

29. Store slash out of the way of construction activities and in operational areas of the facility (e.g., the edge of the facility), if burning is delayed.

Gates 30. Install construction fencing around newly cleared areas outside of the existing facility sites following clearing.

8.0 TOPSOIL MATERIAL HANDLING AND GRADING Introduction The following mitigation measures will be implemented, where applicable by Trans Mountain, its Contractors and Subcontractors during topsoil handling and grading activities.

Objective The objective of these mitigation measures is to avoid or reduce effects on topsoil productivity, surface drainage patterns, terrain contour and slope stability in order to facilitate reclamation of disturbed areas.


Environmental Features 1. Refer to mitigation measures provided under the Staking/Flagging/ Fencing and Signage headings in subsection 7.1. In advance of topsoil handling, confirm the placement of stakes, flags and signage along the construction sites. Replace any stakes, flags and signage as required.

2. Review locations to be avoided during topsoil salvage and grading activities.

Wind Erodible Soils 3. Implement measures to avoid or reduce the effect of soil pulverization and erosion by wind, where warranted (refer to the Soil/Sod Pulverization Contingency Plan in Appendix B). Soil erosion measures are warranted where soil properties present a moderate to high risk of soil erosion; where evidence of drifting is present; where the biological soil crust has been disturbed or as approved by an Environmental Inspector.

Signage 4. Stake and label topsoil, transition and subsoil piles to assist in identification during reclamation activities.

Soil Handling Contingency Measures

5. Implement the Soil Handling Contingency Plan (Appendix B) during topsoil salvage if any of the following are encountered: • little or no topsoil • poor colour separation between topsoil and subsoils; • stony subsoils or topsoil; and • uneven boundary between topsoil and subsoil.

6. Implement the Wet/Thawed Soils Contingency Plan (Appendix B) during wet or thawed soil conditions when soils are too wet to support a particular construction activity. Soils will be considered to be excessively wet when the planned activity could cause damage to soils and result in a soil condition that would have a negative impact on reclamation activities. The decision to continue or suspend particular construction activities on lands with excessively wet/thawed soils will be made by the Construction Manager in consultation with an Environmental Inspector.

Topsoil Salvage 7. Salvage topsoil from the development zone and areas to be graded within the facility footprint that will be disturbed during construction (Detail 4 in Appendix C).

Topsoil Salvage Depth 8. Salvage all available topsoil unless the material is unsuitable (e.g., bedrock, gravel, rock, disturbed land). Where soils are not readily distinguishable by colour, an Environmental Inspector and a Resource Specialist will provide direction based on an evaluation of soil texture and structure.

9. Salvage very shallow surface soils to a minimum depth of 15 cm. If minimum depth of topsoil cannot be salvaged because the underlying material is unsuitable (e.g., bedrock, gravel, rock), salvage all available topsoil.


01-13283-GG-0000-CHE-RPT-0027

Page 8-2


Topsoil Salvage – Frozen Soil Condition

10. Rip frozen topsoil to the same depth as the salvage requirements if a frozen topsoil cutter or topsoil mulcher (or equivalent) is not available. Do not over rip and avoid overstripping.

Storage of Topsoil/Subsoil

11. Map and sign the locations of topsoil piles on as-built drawings to ensure that they can be easily located in the future to support reclamation efforts at the site.

12. Should quantities of salvaged topsoil reduce the practicality of on-site storage, haul excess material off-site for disposal at an approved location or as approved by Trans Mountain.

13. If off-site movement of salvaged topsoil or subsoil is required, adhere to Conditions specified in the applicable permits, where indicated.

Erosion by Wind 14. Tackify, apply water or snow, or pack the topsoil stockpile if soils are showing signs of wind erosion (refer to the Soil Erosion and Sediment Control Contingency Plan in Appendix B).

15. Vegetate the topsoil stockpiles and areas of vegetation disturbed during construction to stabilize topsoil and to reduce weed growth, where warranted.

16. Apply tackifier to topsoil stockpiles in areas of known disease concern when there is potential for topsoil transfer during windy conditions, or if topsoil stockpiles are to be maintained over the winter, to prevent the possible spread of clubroot or other disease.

17. Assess the wind erosion hazard, competency of the sod and potential for soil pulverization due to droughty soils. Implement measures applicable to droughty, wind erodible soils to reduce the effect of soil pulverization and wind erosion (refer to the Soil/Sod Pulverization Contingency Plan in Appendix B).

Dust Control 18. Ensure the dust control measures provided under the Access Road Use and Maintenance heading in subsection 7.2 are implemented as warranted.

19. If there is potential for landowners and/or occupants to be affected by dust emissions, consult with land agents to provide opportunity to report on issues and implement corrective actions, if warranted.

20. Water down the construction footprint, when warranted to reduce or avoid the potential for dust emissions due to soil pulverization. Increase the frequency of watering roads and sites during periods of high risk (e.g., high winds). Additional dust abatement measures (e.g., covering topsoil stockpiles, applying a tackifier) will be implemented, when warranted and approved by an Environmental Inspector .

21. Ensure that watering of roads and/or the construction footprint does not generate excessive formation of surface water accumulation (i.e., puddles or excessive mud generation) or result in overland water flow or sedimentation of nearby watercourses, wetlands or lakes.

Grading 22. Ensure that there is no grading beyond the stakes. Grade only those areas essential for construction.

23. A separation layer (e.g., geotextile material, straw, hydromulch) will be required before placement of grade material onto undisturbed topsoil.


01-13283-GG-0000-CHE-RPT-0027

Page 8-3


Grading (cont’d) 24. Grade, if required, to level the surface to be developed. Grade the surface to facilitate water drainage into water conveyance features (e.g., ditches and culverts).

25. Ensure that graded material does not migrate off-site.

26. Keep the grade spoil stockpile separate from topsoil stockpile/berm. Maintain an adequate separation to avoid admixing between topsoil and grade subsoil stockpiles (Detail 4 in Appendix C).

27. Ensure that grade spoil does not mix with topsoil or foreign material (e.g., coarse woody debris).

28. Clearly identify grade spoil with signs or staking.

Drainage, Erosion and Sediment Controls

29. Install temporary drainage, erosion and sediment control structures following grading, where warranted. During construction, inspect these structures to ensure functionality and repairs will be completed as required (i.e., rain event).

Monitor Soil Stockpiles 30. Monitor soils stockpiles during the growing season for wind and water erosion, and weed growth until the soils are replaced. Implement additional mitigation measures to control erosion and weed growth, when warranted as indicated in the Soil Erosion and Sediment Control Contingency Plan (Appendix B) and the Weed and Vegetation Management Plan (Section 5.5 of Volume 6 of the Environmental Plans).

9.0 FACILITY CONSTRUCTION Introduction The following mitigation measures will be implemented, where applicable by Trans Mountain, its Contractors and Subcontractors during topsoil handling and grading activities. Environmental Facility Drawings have also been prepared (Appendix E) and should be reviewed prior to construction to review key issues that have been identified and mitigation measures that are to be implemented for each facility site.

Objectives The objectives of these mitigation measures are to:

• ensure that construction activities are conducted in accordance with all approval Conditions and permits; and

• avoid or reduce potential adverse effects associated with general facility construction activities.

Activity/Concern Mitigation Measures Site Preparation 1. Do not drive or set equipment on portions of the facility site where

unsalvaged and unprotected topsoil is present in order to avoid rutting and subsequent topsoil and subsoil admixing.

Hotline Exposure/Hydrovac

2. Ensure that all hydrovac tanks are clean and free of contaminants prior to arriving on-site.

3. Implement the appropriate measures presented in the Hydrovac Cutting Handling and Disposal Management Plan (Section 3.3 of Volume 6 of the Environmental Plans) and the Contaminated Sites Discovery Contingency Plan (Appendix B) if potential contamination of hydrovac materials is encountered or suspected. Ensure hydrovac slurry that is suspected to be contaminated is stored and disposed of in accordance with applicable regulatory requirements.

4. Empty clean hydrovac slurry onto subsoil at sites approved by an Environmental Inspector. Ensure that hydrovac material is contained within the designated release area (i.e., will not migrate to a watercourse or wetland, or onto topsoil).

5. Backfill and compact all hydrovac holes during rough clean-up with sand or loose, dry material approved by the Environmental Inspector to ensure settling of material does not pose a hazard for wildlife or livestock.

Excavation 6. Where groundwater and/or soil contamination is suspected, implement the Contaminated Sites Discovery Contingency Plan (Appendix B). Refer to the Contamination Identification and Assessment Plan provided in Section 3.2 of Volume 6 of the Environmental Plans for areas of known contamination encountered by the Project.

7. Fence the perimeter of the site for safety and security reasons, as well as to protect against intrusion by wildlife. Limit the duration of time that the excavations will be left open to reduce the amount of sloughing, frost penetration.


01-13283-GG-0000-CHE-RPT-0027

Page 9-2

Activity/Concern Mitigation Measures Excavation (cont’d) 8. Ensure that contaminated soil and water, if present, are not transported

off-site or disposed until analytical results have been received as per Federal and Provincial regulations and legislation as determined by the Contaminated Sites Resource Specialist.

9. Dispose of excess rock displaced from excavation at an approved location, as approved by an Environmental Inspector.

Blasting 10. Blast competent bedrock encountered within required depth only if standard excavation methods are not feasible.

11. If wildlife is spotted within the blasting area, use measures recommended by a Resource Specialist to displace wildlife prior to blasting.

12. Utilize warning sirens, blasting mats, blasting controls and monitoring to reduce potential injury to wildlife and humans.

13. Haul excavated spoil that is not suitable for use as backfill (e.g., excess bedrock) and dispose of at locations approved by an Environmental Inspector.

14. Follow appropriate procedures provided in Guidelines for the Use of Explosives in or near Canadian Fisheries Waters (Wright and Hopky 1998) if blasting is necessary near watercourses.

15. Monitor registered or known potable water wells located in close proximity of any blasting prior to and following blasting. This determination will be made based on site-specific conditions. Monitoring will include measurement of well yields, static and pumping water levels, as well as water sampling in accordance with Guidelines for Canadian Drinking Water Quality (Health Canada 2019).

Temporary Soil Stockpile Locations

16. Locate and clearly mark temporary soil storage piles away from grade and subsoil materials, construction activities, and day-to-day operations, as approved by an Environmental Inspector. Ensure temporary soil storage piles are accessible and available for hauling.

17. Locate the soil stockpile sites in upslope positions to avoid disruption of drainage and drainage channels. Ensure that drainage through low areas associated with spring break-up will not impact soil piles.

Dewatering 18. Assess the need for well points or other dewatering methods, prior to excavations, to intercept groundwater at site-specific locations.

19. Delay excavations until immediately prior to construction works at locations with a high-water table or where the risk of sloughing is high.

20. Place pumps onto an impermeable barrier (i.e., secondary containment trays). Pump grey water at least 50 m from the nearest watercourse, wetland or lake in a manner that does not cause erosion or any unfiltered or sediment-laden water to enter a waterbody. If, during pump-off, the pump-off water indirectly enters the watercourse or waterbody, pump-off activities will be suspended for re-assessment.

21. Install a diffusion device (e.g., sheet of plywood, wood pallet) to reduce the potential for erosion, and a sediment control device (e.g., filter bag) on the end of the discharge hose to contain any of the sediment that is suspended in the water. If a filter bag will be used, ensure that the filter bag is properly sized to match the pumping pressure.


01-13283-GG-0000-CHE-RPT-0027

Page 9-3

Activity/Concern Mitigation Measures Dewatering (cont’d) 22. Dewater the excavation sites if existing or anticipated (based on

precipitation forecasts) water levels in the excavation could overwhelm existing water control measures.

23. Use floating suction hose and elevated intake, or other measures approved by an Environmental Inspector, to prevent soil material from being sucked from the bottom of the excavation.

24. Monitor the water discharge site to ensure that erosion, sediment loading, flooding or icing does not occur. Suspend dewatering and either apply erosion control measures, reduce the rate of discharge site or move the discharge site to a different location if it appears that the above effects could occur.

25. Ensure that landowner/Appropriate Government Authority approval is in-place before pumping water off the construction footprint.

26. All areas of sediment loading will be properly cleaned up and the soil re-located back onto the Project Footprint.

27. Adhere to the Contamination Discovery Contingency Plan (Appendix B) where water that has been potentially contaminated with hazardous materials is to be discharged to the environment. Prior to dewatering, a Contaminated Sites Resource Specialist will be contacted, and samples of the potentially contaminated material will be collected for testing, as warranted. Measures will be taken to contain the potentially contaminated water on-site and may include the use of tank trucks to haul contaminated water to a Trans Mountain-approved disposal facility and in accordance with the Waste Management Plan in Section 3.1 of Volume 6 of the Environmental Plans and the Spill Contingency Plan (Appendix B). Take steps to ensure the intake is submerged below the surface sheen and use sorbent booms to keep the sheen away from the pump intake.

Site Runoff Control 28. Install drainage control features that ensure that runoff originating off-site will not be allowed to enter the development area.

29. Provide surface drainage of adequate capacity across the facility site.

30. Ensure that sediment-laden storm and melt water runoff from the facility site do not directly drain into a watercourse or wetland.

Drainage, Erosion and Sediment Controls

31. Install temporary drainage, erosion and sediment control structures following grading, where warranted. During construction, inspect these structures to ensure functionality and repairs will be completed as required (i.e., rain event).

Gravel 32. In areas where a gravel pad will be established (i.e., where infrastructure will be installed and in areas that will be subject to travel during the operations phase of the Project) grade the gravel pad in such a manner as to ensure that the pad does not interfere with the local surface drainage pattern.

Bird Deterrents 33. Install guards and/or wildlife protectors, where warranted (e.g., electrical substations), at the facility to reduce the risk of bird nesting.

The following mitigation measures will be implemented where applicable by Trans Mountain, its Contractors and Subcontractors during clean-up and reclamation.

Objectives The objectives of clean-up and reclamation mitigation measures at facilities are to:

• effectively use reclamation techniques that prevent topsoil loss from wind and water erosion;

• establish a vegetative cover compatible with surrounding vegetation and land uses, where applicable;

• comply with approval Conditions, including permits and commitments; and

• re-establish facility sites in a stable condition.


Scheduling 1. Follow activity restriction guidelines and road bans, and consider spring melt when scheduling clean-up and reclamation activities.

2. Commence clean-up activities as soon as practical following construction.

3. Reclaim disturbed lands within one growing season following construction if feasible.

4. Determine the appropriate schedule for seeding and for planting of seedlings or trees and shrubs, where applicable.

Re-contouring 5. Recontour disturbed lands to stable profiles and to meet operational requirements.

Erosion Control 6. Implement appropriate erosion control measures (e.g., soil compaction, soil covers, seeding, mulch and/or tackifiers) to stabilize soil berms, grade cuts, fills and other disturbed lands as warranted (Detail 2 in Appendix C).

7. Establish long-term topsoil storage berms at locations away from regular facility operations and areas with potential for overland water flow.

Sediment Fences 8. Install temporary sediment fences, where warranted, to control sedimentation prior to final clean-up (Detail 1 in Appendix C).

Drainage 9. Ensure ditches and culverts are in-place and free of obstructions to facilitate site drainage.

Topsoil Replacement 10. Replace topsoil evenly over disturbed land surfaces to pre-construction soil depths where reclamation will occur.

Equipment/ Vehicle Travel

11. Limit approved equipment or vehicle access and passage over surfaces where topsoil has been replaced.

Garbage and Debris 12. Dispose of all remaining garbage and debris from the facility construction site at Trans Mountain-approved disposal locations.

Seeding 13. Seed disturbed lands as soon as practical following replacement of topsoil. See recommended seed mixes for facilities by location in the RSMT (Appendix D).

Page 11-2


Scheduling 10. Follow Project defined least risk windows for water withdrawal unless otherwise approved by the Appropriate Government Authority.

Water Sources 11. Identify potential test water sources and discharge sites during desktop studies followed by a reconnaissance of the site with an Environmental Inspector or designate

12. Determine test water needs for each facility.

13. Identify an alternate test water source if the intended water source will provide an inadequate volume for testing purposes. The Contractor will assist Trans Mountain in obtaining required approvals and/or permits, or the provision of required notifications.

14. Confirm that adequate water volume is present for the testing program.

Sump Excavation 15. Ensure that the excavation of sumps for use in withdrawing water are approved by the Environmental Inspector.

16. Where excavation of a sump in the substrate of the water source is necessary, employ sediment reduction methods (e.g., isolation dams, sediment mat, sediment fence, sandbag and coffer dam), where warranted.

Erosion Control 17. Place water pumps on stable substrate at the water source and stabilize approaches to water sources, where warranted, to ensure that accelerated erosion will not occur during pump, hose and/or fill line equipment installation, use or removal.

18. Monitor fill and discharge lines for leaks. Repair or control leaks to prevent erosion.

Isolate Pumps 19. Isolate test pumps, generators and fuel storage tanks with secondary containment to capture and retain any spills/leaks of fuels or lubricants.

Screen Intake 20. Ensure that pump intakes are placed in a manner that reduces or avoids disturbance to the streambed and are screened in accordance with DFO’s screening requirements, to prevent the entrapment of fish or wildlife (Freshwater Intake End-of-Pipe Fish Screen Guideline [DFO 1995]).

21. Utilize screen pump intakes with a maximum mesh size of 2.54 mm and with a maximum approach velocity of 0.038 m/s, at all water withdrawal locations.

22. Ensure screens are monitored and remain clear of debris.

Withdrawal 23. Follow the mitigation measures related to water withdrawal provided in the Water Withdrawal and Discharge Procedures Management Plan (Section 8.6 of Volume 6 of the Environmental Plans) during hydrostatic testing. Adhere to the specifications of the Project Hydrostatic Test Plan, to be filed with the CER 90 days prior to commencing hydrostatic testing.

24. Track the volumes of water used and ensure the water level in a lake does not fall more than the maximum amount approved by the BC Water Sustainability Act or Alberta Water Act approvals once water withdrawal has started. Retain a copy of the Hydrostatic Test Plan, as well as the water withdrawal permit on-site and ensure an Environmental Inspector has reviewed the water withdrawal permit prior to the commencement of withdrawal activities.

25. The withdrawal rate and volume will not exceed applicable permit values.

Chemical Recovery 26. Recover chemical additives, if used during winter, and return to the supplier or dispose of in accordance with appropriate government legislation. Ensure the method and location of disposal has been approved by Trans Mountain and is in accordance with applicable regulations and regulatory direction.

Dewatering 27. Follow all dewatering measures outlined in the Hydrostatic Test Plan and the Water Withdrawal and Discharge Procedures Management Plan (Section 8.6 of Volume 6 of the Environmental Plans).

28. Monitor discharge locations to ensure that no erosion, flooding or icing occurs. If conditions become saturated to the extent that adequate natural filtration is no longer occurring, suspend dewatering and move the discharge to another approved location (confirm that appropriate approvals and, if warranted, soil testing have been completed) or construct a holding pond for the water and release the water when natural filtration is feasible.

29. Ensure the areas that are to receive discharged water are approved by an Environmental Inspector in accordance with the Appropriate Government Authority guidance.

30. Dewater onto approved areas where water will be filtered through vegetation and soils before returning to a watercourse, wetland or lake. Provide scour protection (e.g., use of rock aprons, plastic sheeting, plywood and straw bales) or an energy diffuser (e.g., cone with baffles and frog’s foot) at the discharge site as directed by an Environmental Inspector. The rate of discharge will be reduced if these measures are ineffective.

31. Ensure water discharge is conducted in accordance with required discharge approvals. Unless otherwise approved, do not dewater directly or indirectly back into a watercourse, wetland or lake.

32. Preserve water quality to the extent feasible including preventing the introduction of foreign material (e.g., debris, sediment) into the receiving watercourse or wetland.

Sample Collection 33. Collect samples of source water, hydrostatic test water and soil of the receiving environment prior to discharge to land or water and analyze according to the parameters listed in Water Withdrawal and Discharge Procedures Management Plan (Section 8.6 of Volume 6 of the Environmental Plans).

Pigging Debris 34. Collect pigging debris and dispose of it at an acceptable location (e.g., landfill). Dispose of remaining construction debris in accordance with the Appropriate Government Authority.

1.0 CONTAMINATION DISCOVERY CONTINGENCY PLAN 1.1 Pre-Job Planning

A list of areas with moderate to high potential risk for contamination is provided in Contamination Identification and Assessment Plan (Section 3.2 of Volume 6 of the Environmental Plans). In accordance with the Contamination Identification and Assessment Plan, a Contaminated Resource Specialist will ensure the appropriate response and mitigation is carried out during construction in the identified high risk areas. When working in areas of moderate or high risk, workers shall be informed of the potential to encounter contamination. In the event unexpected contamination is encountered, this Contamination Discovery Contingency Plan will be initiated.

Recognition and Response Identification of Contamination Soil, surface water and groundwater contamination can generally be recognized by one or more of the following:

• unusual, hydrocarbon or chemical odour;

• visual sheen;

• visual free product (oil or other product);

• visual staining; and/or

• high soil vapour concentrations.

Contamination will be identified through visual field observation and confirmed by laboratory analysis.

Asbestos Visual field indicators to identify asbestos or asbestos-containing material (ACM) (>1% by weight of asbestos fibres and powder/dust or friable) include: serpentine rock, fibrous appearance, greasy lustre; brake pads, cement piping, vinyl tiles, home insulation, cement siding); and for asbestos deposit areas: former landfills, asbestos dumps including other signs of waste deposition (e.g., fill, liners, surficial evidence). The microPHAZIR™, by ThermoFisher Scientific, is the tool for field screening for asbestos or ACMs when excavation during construction is performed where asbestos or ACMs are suspected.

The microPHAZIR™ is handheld portable analyzer that is demonstrated to provide non-destructive screening of six types of asbestos fibres (i.e., Chrysotile, Anthophyllite, Tremolite, Actinolite, Amosite/Crocidolite) via infrared analyses. ThermoFisher Scientific demonstrated the microPHAZIR detection limits are for concentrations greater than 1% asbestos fibres determined by analyzing asbestos reference standards with known concentrations

Notification Framework Upon the identification of contamination, work in the area will cease immediately and the Environmental Inspector will be notified. The Environmental Inspector will immediately notify a Trans Mountain representative.

A Contaminated Sites Resource Specialist with experience in contaminated sites will be contacted by the Environmental Inspection Team. The Resource Specialist will provide guidance on immediate management of the potential soil and/or groundwater contamination.

Upon confirmation, Trans Mountain representatives will notify the Appropriate Government Authorities, if required. The Land Agents and/or Lands Group, Stakeholder Engagement and Communication Team, and the Indigenous Relations Team will also determine the requirement for notification of affected landowners and/or occupants and Indigenous groups.


01-13283-GG-0000-CHE-RPT-0027

Page B-4

Health and Safety Upon discovery of suspected contamination, the health and safety of personnel and the public is the first priority. Contractors and personnel on-site will suspend all work in the area, shut-down equipment and immediately notify the Construction Manager, or designate, and an Environmental Inspector. Appropriate personal protective equipment (PPE) for the hazard will be worn and all reasonable measures will be taken to ensure that the health and safety of anyone in the immediate area is preserved. Personnel and Contractors will employ all measures and requirements outlined in the Construction Health and Safety Management Plan as well as any other measures or requirements.

Signage will be posted in areas with moderate to high potential risk for contamination to alert workers of the increased risk. In areas potentially affected by asbestos or ACM, personnel will wear appropriate PPE including half mask or full mask respirators with HEPA filters for which they have previously been fit-tested. Personnel conducting air sampling will be required to demonstrate engineering control enacted to mitigate dust are effective.

Interim Mitigation The Environmental Inspector and Contaminated Sites Resource Specialist must be consulted when determining the necessary mitigation measures that are to be implemented when it is safe to do so. The Resource Specialist may be deployed to the site to conduct sampling and contamination mitigation response when required. In all instances, the migration of the contamination from the disturbed area must be minimized. Mitigation measures may include, but are not limited to:

• segregating contaminated soil for later sampling and/or analysis and disposal;

• placing contaminated soil onto an impermeable surface;

• covering contaminated soil with an impermeable cover in cases where precipitation may cause runoff;

• constructing berms to control runoff, in cases where runoff is imminent;

• stopping contaminated water discharge;

• storing contaminated water in tanks for later sampling and/or analysis and disposal;

• conducting soil and groundwater laboratory analysis based on analytical parameters for site history and land use; and

• collecting in-situ samples (soil or groundwater) from the construction footprint, including the excavation floor and walls surrounding the suspected impacts, and samples of the suspected impacted soil or groundwater, and submitting to an approved laboratory under the direction of a Resource Specialist.

If asbestos or ACMs are discovered through field screening during construction:

• excavation activities are to cease; and engineering controls are to be enacted to mitigate dust, including soaking the area of suspected asbestos with water; and

• soils containing, or suspected to contain asbestos will be segregated, wetted and covered until appropriate disposal is determined, following receipt of laboratory analyses.

Potential contaminants of concern, sampling methods, analytical testing details, monitoring and reporting methods are outlined in the Contamination Identification and Assessment Plan in Section 3.2 of Volume 6 of the Environmental Plans.

Signage will be posted in the area of suspected contamination to alert workers of the increased risk.


01-13283-GG-0000-CHE-RPT-0027

Page B-5

Mitigation measures will be implemented as soon as possible following the discovery of contamination. The implementation of mitigation measures will be based on the severity and risk of the contamination that is discovered.

Contamination Management Requirements In the event contamination is discovered during Project construction, follow the measures outlined in the National Energy Board’s (NEB’s) Remediation Process Guide (NEB 2011) for the Project Footprint.

Contaminated material will be disposed of at approved facilities in accordance with Provincial and Federal regulations and in accordance with the Waste Management Plan (Section 3.1 of Volume 6 of the Environmental Plans).

Excavations in which contaminated soil and/or groundwater has been discovered must not be backfilled until authorization has been given by the Construction Manager and Environmental Inspector. Any soil material brought on-site to fill excavations must be approved by the Environmental Inspector prior to use.

Contaminated soil and water must not be transported off-site or disposed at a Trans Mountain-approved waste facility of until analytical results have been received as per applicable Federal and Provincial regulations and as outlined in the Contamination Identification Assessment Plan (Section 3.2 of Volume 6 of the Environmental Plans). The Construction Manager and the Environmental Inspector will provide notification confirming when excavations can be backfilled.

2.0 FIRE CONTINGENCY PLAN The Contractor(s) will develop a Fire Contingency Plan and a Fire Prevention Plan as part of their Emergency Response Plan (ERP) that will include, at a minimum, the guidelines provided in the TMEP Health and Safety Management Program and associated Emergency Management Program.

Fire Prevention Measures The following standard measures will be adhered to during construction of the Project:

• Prior to commencement of construction, the Contractor(s) will designate a Fire Boss. The Fire Boss will be familiar with fire suppression techniques, equipment and procedures.

• All vehicles will carry firefighting equipment (e.g., Pulaski axes, shovels and backpack pumps) in sufficient quantities so that each worker has access to, at minimum, one hand tool with which to carry out fire suppression work. All motorized equipment must carry a fully charged fire extinguisher. The Fire Boss will ensure that fire extinguishers are present and meet requirements. The Fire Boss will also ensure compliance under the Alberta Forest and Prairie Protection (Ministerial) Regulation as it relates to firefighting equipment.

• The Fire Boss will ensure that equipment is cleaned periodically to reduce the build-up of debris in areas which could pose a fire hazard (e.g., belly pans of crawler tractors).

In the Event of a Wildfire The following response measures will be implemented, as warranted, in the event of a fire.

• Commence fire suppression measures immediately upon detection of a fire provided that current fire behaviour allows personnel to safely proceed.

• Report location of fire as well as size, wind direction, fuels burning and immediate values at risk to the Fire Boss.

• The Fire Boss will report all wildfires immediately and relay general fire information to the Senior Compliance Advisor who will advise the Appropriate Government Authorities.

• All equipment and personnel will be made available to control the fire. Suppression efforts will take into consideration fire behaviour, safety, training and fitness of personnel as well as equipment availability.

• The Fire Boss will inspect the fire as soon as possible and take charge of directing suppression measures until relieved by a responding authority official.

• Moveable material, particularly explosive or flammable materials and/or vehicles will be promptly moved to a safe location whenever there is a possibility of being endangered by fire.

• Fire suppression efforts will continue until the fire is extinguished, until it is no longer safe for Project personnel to respond to the fire, or until otherwise notified by the Appropriate Government Authority (i.e., Alberta Environment and Parks [AEP], BC Ministry of Forests, Lands, Natural Resource Operations and Rural Development [BC MFLNRORD]).

• The Fire Boss will ensure that all burning embers are extinguished and will monitor burn area for smouldering material. The Fire Boss employ infrared scanning equipment, if available, to detect any residual hot spots.

3.0 HERITAGE RESOURCES CONTINGENCY PLAN **Note: Personnel are NOT permitted to collect and/or keep any artifacts.

The following provides contingency measures for the discovery of heritage resources during construction of the Project.

Heritage Resource Discovery During Construction If suspected heritage resource sites are discovered during construction, implement the following measures:

• Prohibit the collection of any historical, archaeological or palaeontological resources by Project personnel except for qualified Heritage Resource Specialists acting as authorized by the appropriate regulator/permit.

• Suspend work immediately in the vicinity (within 30 m) of any newly identified archaeological, palaeontological or historical resource sites (e.g., modified bone, pottery fragments and fossils).

• Clearly mark the sites using fencing and flagging to ensure avoidance and create a no-go zone.

• Notify the Environmental Inspector who will notify the Construction Manager, the Heritage Resource Specialist and Senior Compliance Advisor, who will notify Appropriate Government Authority.

• Work within the 30 m no-go zone of potential discovery may not resume until the measures as follows are implemented.

If confirmed to be a heritage resource, Trans Mountain will notify the Appropriate Government Authority and Indigenous group(s), as required.

If confirmed to be a heritage resource and as required, a Heritage Resource Specialist will develop an appropriate mitigation plan in consultation with the Contractor, Environmental Inspector, the Construction Manager, the Appropriate Government Authority, as well as, the applicable Indigenous group(s). The mitigation measure options available include those measures for site avoidance, systematic data recovery and monitoring/surveillance as described previously.

Human Remains Discovered During Construction If suspected human remains are discovered during construction, implement the following mitigation measures:

• Suspend work immediately in the vicinity (within 30 m) of the newly identified human remains. Work at that location may not resume until the measures below have been implemented.

• The Environmental Inspector will notify the Construction Manager, the Chief Activity Inspector, the Heritage Resource Specialist, and if warranted, the local police and Appropriate Government Authorities.

• If there is potential for disturbance to the site due to a high traffic area or high public visibility, assign employees to stand watch until the Heritage Resource Specialist arrives.

• Stake or flag off the location to secure avoidance and develop a no-go zone.

• Cover any exposed remains with clean plastic sheeting, tarpaulin, blanket or other covering until the Heritage Resource Specialist is present.

• Do not backfill. If excavated fill has been loaded into a truck, empty the excavated fill at a nearby secure location for the local police and Heritage Resource Specialist to inspect. Stake or flag off the location of backfill to secure avoidance and develop a no-go zone.


01-13283-GG-0000-CHE-RPT-0027

Page B-9

• The Contractor will only resume work within the no-go zone once the archaeological and forensic studies are complete, clearance has been granted by the Appropriate Government Authorities, and Trans Mountain has been advised that work can continue.

• If confirmed to be historic human remains, Trans Mountain will notify additional stakeholders (e.g., Indigenous groups) as required.

• If confirmed to be a historic human remains and as required, a Heritage Resource Specialist will develop an appropriate mitigation plan in consultation with the Contractor, Trans Mountain, the Appropriate Government Authority and the applicable Indigenous group(s).

4.0 RARE ECOLOGICAL COMMUNITIES OR RARE PLANT SPECIES DISCOVERY CONTINGENCY PLAN

In the event unidentified ecological communities or rare plants (vascular plant or bryophyte including moss or liverwort or lichens) are discovered on or within 30 m of the facility construction and/or associated components (i.e., borrow sites, temporary access roads and temporary workspace [TWS] footprint) prior to or during construction, Contractor personnel will follow the measures outlined as follows.

• Note the location of the potential rare plant, lichen or ecological community relative to the facility.

• Notify the Environmental Inspector.

• Send a photograph of the potential feature and any additional details (e.g., habitat characteristics) regarding the feature and site to Trans Mountain to provide to the a Vegetation Resource Specialist.

• Avoid further disturbance or within 10 m of the location until the Vegetation Resource Specialist has been consulted.

• If warranted, the Vegetation Resource Specialist will be required to attend the site and will determine if site-specific mitigation is required.

• The Vegetation Resource Specialist will then develop an appropriate site-specific mitigation plan in consultation with the Environmental Inspector and the Contractor based on the Rare Ecological Community and Rare Plant Population Management Plan (Section 5.3 of Volume 6 of the Environmental Plans).

Page B-11

5.0 SOIL EROSION AND SEDIMENT CONTROL CONTINGENCY PLAN Where soil erosion by wind or water is evident or imminent during facility construction, the necessary Contractor equipment and personnel will be made available to prevent and/or control the sedimentation and/or erosion. The Environmental Inspector in consultation with the Construction Manager, or designate, and Environmental Manager will determine appropriate mitigation measure(s) to be implemented to control soil erosion and/or sedimentation or other soil handling problems that may be encountered.

The Senior Compliance Advisor must be notified, who will notify the Appropriate Government Authorities (i.e., AEP, British Columbia Ministry of Environment and Climate Change Strategy [BC ENV] and Canada Enegy Regulator [CER]), as required and as soon as practical, that contingency measures are being/have been implemented (Contacts provided in Appendix A of the Facilities Environmental Protection Plan [Facilities EPP]). A record will be made of the location, timing, reason for implementation and measures implemented.

One or more of the following erosion control options listed as follows will be implemented, if warranted, where soil erosion is observed.

Soil Erosion by Water • Temporarily shut-down construction until the risk of erosion has been reduced or conditions improve.

The decision to shut down construction will be made following a discussion involving the Contractor, the Construction Manager, or designate, and an Environmental Inspector.

• Install sediment fences near the base of slopes if adjacent to a watercourse/wetland.

• Construct/install temporary berms of subsoil, logs, coir logs, or sandbags on slopes where the risk of erosion is high.

• Implement one or a combination of the following measures if re-grading:

salvage topsoil and store away from the area to be re-graded;

construct temporary diversion ditches, berms and sediment ponds to direct water flow off the footprint;

re-grade rills and gullies; and

replace salvaged topsoil.

• Implement one or a combination of the following long-term mitigation techniques:

construct cross ditches or berms decreasing the spacing on steeper slopes or on more erodible soils;

armour the upslope face of berms with coir erosoin control blanket, logs or sandbags;

apply erosion control blanket, mulch or tackifier to hold soil;

re-seed and hand rake an annual cover crop, hydroseed or apply seed and install erosion control blankets; and

transplant native shrubs root clumps, install live willow stakes, brush layering or use other bioengineering techniques.

Soil Erosion by Wind • Temporarily shut-down construction at the location where erosion is occurring until the risk of erosion

has been reduced or conditions improve; the decision to shut down construction will be made following a discussion involving the Contractor, the Construction Manager and an Environmental Inspector.


01-13283-GG-0000-CHE-RPT-0027

Page B-12

• Consider using one or a combination of the following techniques if soil erosion by wind of the topsoil stockpile is of concern:

apply water or tackifier (at rate recommended by the distributor) to the topsoil stockpile; and

tamp the topsoil stockpile with suitable equipment.

• Consider using the following techniques if soil erosion by wind is of concern after topsoil replacement:

seed with annual or biannual cereal or short-lived annual grass cover crop species;

apply hydromulch or tackifier; and

install wind fences.

6.0 SOIL HANDLING CONTINGENCY PLAN During construction of facilities and associated components (i.e., borrow sites, temporary access roads and TWS), the following problems may arise which may result in loss of soil productivity if not addressed. Mitigation measures are suggested as follows, which may lessen the effects of the identified conditions or concerns associated with construction.

Little or no Topsoil • Salvage to colour/texture change or to 10 cm, whichever is greatest.

Stony Subsoils or Topsoil • Attempt to use conventional equipment (e.g., dozers) to salvage topsoil. Employ excavators with

clean-up buckets, if dozers are ineffective.

Uneven Boundary Between Topsoil and Subsoil • Utilize equipment capable of fine depth adjustments when salvaging topsoil. Avoid overstripping and

admixing of topsoil with subsoil.

• Salvage transitional material to the complete colour/texture change at the subsoil boundary.

7.0 SOIL/SOD PULVERIZATION CONTINGENCY PLAN The CER will be notified as soon as practical after the implementation of soil/sod pulverization contingency measures.

Criteria for Implementation Pulverization Topsoil pulverization is loose and powdery or granular topsoil for a depth of 5 cm or more over a lateral distance of 20 m or more along the construction footprint. Pulverization may occur on unsalvaged, well-sodded lands, and on cultivated lands with silt or clay-textured soils. The Soil/Sod Pulverization Contingency Plan will be implemented where sod integrity on hay and/or tame pasture lands or topsoil has been disturbed to the extent that the soil/sod will not infill naturally within the same time frame as the adjacent soil, or there is an unacceptably high risk of soil erosion by wind.

The following contingency measures will be implemented where pulverization is occurring, and topsoil was not fully salvaged from the working area of the Project Footprint. Locations where these measures apply will be determined during construction by an Environmental Inspector in consultation with the landowner and/or occupant or the applicable Crown land authority.

• Provide alternative access to the construction footprint to avoid areas prone to soil/sod pulverization.

• Minimize traffic, particularly rubber-tired vehicles, in areas where pulverization is prone to occur.

• Use equipment with low-ground pressure tires/tracks (e.g., wide pad tracks) during salvaging and replacement of topsoil.

• Salvage a wider area of topsoil from the Project Footprint.

• Salvage topsoil from all travel areas in silty soil.

• Apply water to pulverized areas in attempt to freeze down the pulverized topsoil to avoid wind erosion and possibly to the extent that construction traffic can be allowed to travel across.

• Apply tackifier and mulch to control wind erosion of pulverized topsoil.

• For shorter areas of pulverized soil where traffic cannot feasibly be restricted, apply matting of sufficient strength to support equipment and vehicles.

Clean-up and Reclamation Implement the following measures during final clean-up and reclamation activities along portions of the construction footprint where soil/sod pulverization occurred prior to contingency measures being implemented.

• Lightly cultivate the affected areas in two directions with a spike cultivator or a scarifier.

• Cultivate an area approximately 1 m wider than the disturbed area.

• Harrow the area to prepare a seedbed.

• Drill or broadcast seed the area, as appropriate. If broadcast seeding is the preferred method, lightly harrow the area again to incorporate seed and compact the seedbed.

• Straw crimp, if deemed necessary by an Environmental Inspector, on erosion-prone soils.

8.0 SPILL CONTINGENCY PLAN 8.1 Introduction

Guidelines for the safe handling, storage, use and disposal of potentially hazardous wastes as well as spill prevention measures and guidelines for the refuelling and servicing of equipment are provided in Trans Mountain’s Waste Management Plan (Section 3.1 of Volume 6 of the Environmental Plans).

The Contractor(s) shall develop a Spill Contingency Plan as part of their ERP. For spills generated from construction equipment or encountered during construction activities, the Contractor shall include measures in the ERP that are consistent with this Spill Contingency Plan. If a spill results from construction activities affecting third-party utilities or the existing Trans Mountain Pipeline (TMPL) System, the procedures outlined in the Trans Mountain Operational ERP shall be implemented. Roles and responsibilities, compliance and spill reporting procedures for all types and sizes of spills and release events are found in the Compliance Management Plan. The following Spill Contingency Plan provides measures to be incorporated by the Contractor(s) in their ERP.

Contractor shall report all spills to an Environmental Inspector, Environmental Manager and Chief Activity Inspector. Records of all spills through a spill report are to be maintained. The Environmental Inspector will immediately notify Trans Mountain Management that a spill has occurred, so that the Senior Compliance Advisor can notify the Appropriate Government Authorities as required.

The timeline in which the reporting is to take place is dependent on the size of the spill. An immediately reportable spill is defined as a release of a substance that is likely to be an imminent environmental or human health hazard and/or meets or exceeds reportable volumes listed below. Such spills will be immediately reported to the Appropriate Government Authorities and Indigenous groups, as required, by Trans Mountain. Information from all spills will be provided by the Contractor so the appropriate tracking and documentation will be completed by Trans Mountain. Spill reports will be completed and submitted to Trans Mountain within 48 hours.

If there is any doubt that the quantity spilled exceeds reportable levels, the spill will be treated as a reportable spill. The Trans Mountain Regulatory and Compliance Team will determine if the spill should be reported to the Appropriate Government Authorities and Indigenous groups. Crucial information that will be provided to Trans Mountain via the Environmental Inspector shall include:

• name and telephone number of the caller;

• date and time of the call;

• material(s) spilled;

• location of the spill;

• whether the spill has entered or has the potential to enter water;

• estimated quantity spilled;

• cause of spill;

• actions taken to-date;

• assistance required;

• injuries; and

• weather conditions.

Page B-16

In Alberta, a reportable spill is defined by the Alberta Environmental Protection and Enhancement Act as:

• the release has caused, is causing or may cause impairment of or damage to the environment, human health or safety, or property;

• the amount exceeds the quantities or emission levels set out for the substance (see Safety Data Sheets [SDS] and Trans Mountain’s Compliance Mangement Plan);

• the release is into a watercourse or into the groundwater or surface water in any quantity; and/or

• the release is 200 L or more (Transport Canada 1992) immediate reporting quantity for flammable liquids [Class 3]) (Attachment B2).

In BC, a reportable spill is defined by the BC Environmental Management Act as:

• a release of 100 L or more of flammable liquids (i.e., gasoline, diesel, solvents);

• a release of 100 L or more of waste oil (i.e., lubricating oil, cutting oil, gear oil, hydraulic oil or any other refined petroleum-based oil or synthetic oil);

• a release of 25 L or more of engine coolant;

• a release of 25 kg or more of contaminated soils; and/or

• any release enters, or is likely to enter a waterbody or watercourse (Attachment B2).

Refer to the BC Spill Reporting Regulation for further information on reporting thresholds. All spills regardless of size or type material, will be reported by the worker discovering the spill to Environmental Inspector.

Any sites contaminated by a construction related spill will be assessed in consultation with Trans Mountain and remediation will be designed and disposal sites will be identified in accordance with the NEB Remediation Process Guide (NEB 2011). This document will be provided to the Construction Manager, or designate, the Lead Environmental Inspectors and the Environmental Inspectors as part of the Environmental and Compliance Education Program. Emergency contacts are presented in Appendix A of the Facilities EPP.

8.2 General Measures

The following general measures are to be adhered to during construction.

• Maintain appropriate spill containment equipment at all work sites based on risk. The risk potential for site-specific spills will be used to determine the appropriate type of response equipment and material to be stored on-site and suitable location for storage.

• Post specific instructions regarding applicable contacts and appropriate response actions to be taken in the event of a spill in the field construction offices.

8.3 Initial Response

The following actions will be taken upon detection of a spill.

• Ensure personal safety and the safety of others on-site and don appropriate PPE.

• The first person on the scene will execute the actions presented in the Spill Scene Checklist (Attachment B2).

• Report the spill to an Environmental Inspector and Chief Activity Inspector.


01-13283-GG-0000-CHE-RPT-0027

Page B-17

• When notified of a reportable spill, an Environmental Inspector or designate will immediately ensure that the following actions are taken, where applicable:

action is taken to ensure safety of workers and the public;

an on-site Emergency Response Coordinator is designated;

the necessary equipment and personnel are mobilized, and measures are being implemented to stop the source of the spill, if safe to do so, and commence clean-up;

Trans Mountain is immediately notified of the spill;

Trans Mountain Management notifies the Senior Compliance Advisor, who will immediately notify the Appropriate Government Authorities and the CER of the spill if it meets the reporting threshold.;

the Contractor will make the required resources available to contain and clean-up the spill; and

the Contractor shall dispose of the removed material at a Trans Mountain-approved facility.

In the event of an oil spill associated with the existing TMPL, the Contractor must immediately notify Trans Mountain via the 24-Hour Control Centre Emergency Line (1-888-876-6711). In addition, the following actions will be taken:

• ensure action is taken to ensure safety of workers and the public; and

• attempt to contain the spill to the greatest possible extent without endangering the welfare of workers as directed by Trans Mountain until TMPL emergency spill responders arrive.

The Contractor will make the required resources available to TMPL emergency spill responders to facilitate the containment and clean-up the spill.

In the event of a spill associated with a third-party foreign pipeline, the Contractor must immediately notify Trans Mountain via the 24-Hour Control Centre Emergency Line (1-888-876-6711). In addition, the following actions will be taken:

• ensure action is taken to ensure the safety of workers and the public; and

• coordinate the containment of the spill to the greatest possible extent without endangering the welfare of workers until the third-party pipeline owner’s emergency spill responders arrive.

The Contractor will, upon request of the third-party pipeline owner, make resources available to facilitate the containment and clean-up the spill.

8.4 General Spill Containment Procedures

The successful containment of a spill on land or water depends on a variety of factors including: ground cover and topography; hydrogeology; solubility of the material; viscosity of the liquid; water currents; soil permeability; and weather conditions.

The following general guidelines may be followed for containment of spills of hazardous materials.

• Ensure personal safety and safety of others on-site. The first person on the scene will execute the actions listed in the Spill Scene Checklist. This includes a review of the SDS.

• Assess the safety hazards of the situation and don appropriate PPE.

• Remove source(s) of ignition, if safe to do so.


01-13283-GG-0000-CHE-RPT-0027

Page B-18

• Identify the product, stop source and physically contain spill as soon as safe to do so.

• Avoid use of water or fire extinguishing chemicals on non-petroleum product spills since many chemicals react violently with water and chemical extinguishing agents may release toxic fumes. In addition, chemicals may be soluble in water and dispersal makes containment and clean-up more difficult.

• Re-direct traffic away from the contaminated materials.

• Demarcate the spill area when safe to do so to notify workers of impacted area if the spill cannot be immediately cleaned-up (e.g., same day).

• Use berms constructed with materials and equipment in proximity to the site to physically contain a spill on land. Deployment of booms will be necessary to contain a spill and prevent contamination spread on water.

• Clean-up will not be attempted without advice from the Environmental Inspector and Trans Mountain.

• Dispose of impacted materials at a Trans Mountain-approved Waste Facility in accordance with the Waste Management Plan (Section 3.1 of Volume 6 of the Environmental Plans).

8.4.1 Spot Spills

Spot spills are considered to be generally small. Their effects can be minimized and will not result in the suspension of activities if the appropriate actions listed as follows are promptly implemented. All small spills of fuels, hydraulic fluids or hazardous materials must be contained, reported immediately to an Environmental Inspector and cleaned-up.

• An Environmental Inspector will approve methods to remove contaminated soils, in consultation with a Resource Specialist, if warranted. Locations where spot spills occur are to be recorded.

• Dispose of impacted materials at a Trans Mountain-approved facility in accordance with the Waste Management Plan (Section 3.1 of Volume 6 of the Environmental Plans).

• All efforts will be made to clean-up the release. The Contractor shall demonstrate that residual impacts are not left in place; however, if residual impacts remain, the steps to further assessing and remediating the contamination will be developed in consultation with Trans Mountain and in accordance with the guidance set out in the NEB Remediation Process Guide (NEB 2011).

8.4.2 Spills Occurring During On-Site Transportation

The general guidelines listed as follows may be followed for the containment of maerials spilled during transportation.

• Contain spilled product.

• Pump tanker truck or transportation vessel dry (into appropriate containers or alternative tanker truck).

• Remove tanker truck or transportation vessel from the site.

• Recover spilled product.

• Clean-up contaminated area.

• Dispose of impacted materials at a Trans Mountain-approved waste disposal facility in accordance with the Waste Management Plan (Section 3.1 of Volume 6 of the Environmental Plans).

• All efforts will be made to clean-up the release. The Contractor shall demonstrate that residual impacts are not left in place; however, if residual impacts remain, the steps to further assessing and remediating the contamination will be developed in consultation with Trans Mountain and in accordance with the guidance set out in the NEB Remediation Process Guide (NEB 2011).

8.4.3 Spills Adjacent to or into a Watercourse or Wetland

The general guidelines listed as follows may be followed for spills adjacent to or into a watercourse or wetland.

• Construct berms and/or trenches to contain spilled product prior to entry into a watercourse or wetland.

• Deploy booms, skimmers and/or sorbents, if feasible, to contain and recover spilled material from a watercourse or wetland.

• Collect spilled product.

• Clean-up contaminated area including downstream shorelines.

• Dispose of impacted materials at a Trans Mountain-approved facility in accordance with the Waste Management Plan (Section 3.1 of Volume 6 of the Environmental Plans).

• All efforts will be made to clean-up the construction related release. The Contractor shall demonstrate that residual impacts are not left in place; however, if residual impacts remain, the steps to further assessing and remediating the contamination will be developed in consultation with Trans Mountain and in accordance with the guidance set out in the NEB Remediation Process Guide (NEB 2011).

9.0 TRADITIONAL LAND USE SITES DISCOVERY CONTINGENCY PLAN 9.1 Traditional Land Use Sites Identified Prior to Construction

If Traditional Land Use (TLU) sites are identified during supplemental studies with Indigenous groups prior to facility construction or associated components (i.e., borrow sites, temporary access roads and TWS), the sites will be assessed, and appropriate mitigation measures will be determined. Newly discovered TLU sites will be assessed based on the following criteria:

• the location of the TLU site with respect to the area of development;

• the relative importance of the TLU site to the applicable Indigenous group; and

• the potential for an alteration of construction activities to reduce or avoid sensory disturbance.

The mitigation measures listed below have been identified and approved for other TLU sites across the Project. During discussion of the newly identified TLU site, alternative site-specific mitigation strategies may be recommended by Indigenous groups or the Indigenous Monitor(s). The mitigation measures that may be implemented will be dependent on the type of site identified and its proximity to the Project Footprint.

Hunting Hunting and wildlife sites are areas where large mammals such as elk, moose, deer, caribou and bear are commonly harvested. Key wildlife species are identified both in community discussion and by observed game ambushes, blinds and hunting stands, dry meat racks and butchered animal remains. Furthermore, locales where game can be expected (e.g., mineral licks, calving areas and well-used game trails) are typically prized hunting areas.

Mitigation for hunting sites may include the following:

• adhering to species-specific timing constraints, to the extent feasible; and

• limiting or restricting the use of chemical applications to control invasive vegetation.

Trapping Indigenous individuals continue the practice of trapping and snaring for food and pelts. These traps and snares may or may not be located within registered trap lines.

To avoid accidental damage where the construction footprint transects a trap line, mitigation measures may include the following:

• moving of trap line equipment by the trapper prior to construction; and

• maintaining access to the trap line during construction.

Fishing The practice of traditional fisheries relates to the species harvested, fishing techniques and the nature of specific reaches of lakes and rivers. Fishing methods may include but are not limited to angling, jigging, spear-fishing, dip netting, gill netting and the construction and use of fish traps and weirs. While fishing activities vary with changes in seasonal water flow and variation in fish stocks, fisheries often exhibit habitual repeated use.

Fishing areas include waterbodies that are often in proximity to staging areas and/or access points to the waters. Secondary fishing activities relate to the processing of harvests, and may include processing yards, smokehouses, drying racks and fish-grease rendering features.


01-13283-GG-0000-CHE-RPT-0027

Page B-22

Mitigation measures for fishing areas may include the following:

• recording and mapping of fishing locales; and

• strict adherence to the regulations, standards and guidelines set by Appropriate Government Authorities for watercourse crossings.

Plant-Gathering Many Indigenous individuals harvest medicinal, ceremonial and food source plants. Plants are gathered in a variety of environments, which include old forests along watercourses and in rugged or mountainous areas. Detailed information regarding medicinal plants is passed down from the Elders and is considered proprietary by the Indigenous groups.

To avoid the disruption of plant-gathering activities, mitigation measures may include the following:

• limiting or restricting the use of chemical applications to control invasive vegetation;

• replacement of plant species during reclamation; and/or

• avoidance of the site.

Trails and Travelways Travel corridors are essential for conducting traditional activities and accessing cultural landscape features. Trails include well-defined all-terrain vehicle and snowmobile corridors, navigable waterways, river portages, and historical foot, dog sled and pack horse pathways.

Mitigation measures for trails that are crossed by the construction footprint may include the following:

• detailed recording and mapping of the trails within 100 m buffer of construction footprint; in partnership with Indigenous group representatives, a decision is then made about the relative importance of the trail and, if warranted, how best to maintain and control access; and/or

• installing signage or scheduling construction during periods of least effect, where feasible.

Habitation Sites Habitation sites include traditional campsites, cabins and settlements. Camp sites typically have defined hearths (fire rings), de-limbed trees, tent frames and/or miscellaneous cached or discarded camping supplies and equipment. Cabin structures represent a more permanent occupation of the land and include central log or timber-framed structures, traditional activity areas such as drying racks and smoking tents, and ancillary equipment storage areas. A group of cabins or campsites may signify a long-term or intermittent occupation. A settlement may have been used seasonally or throughout the year, depending on location or necessity. The relative size and nature of habitation sites continuously evolve based on how families and communities grow and often expand from campsites to cabins and possibly to settlements.

Mitigation measures for habitation sites may include the following:

• avoidance of the site;

• detailed mapping, photographic recording of the location; and/or

• implementation of detailed recording and controlled excavations.


01-13283-GG-0000-CHE-RPT-0027

Page B-23

Gathering Places Indigenous groups often gather to share in ceremonial activities, exchange items of trade, arrange and celebrate marriages and for other activities as well. In addition, Indigenous grave sites are sometimes recorded in the general area of large gathering places. Such gathering places have historical, ceremonial, cultural and economic significance to Indigenous groups.

Potential effects on gathering places may be mitigated through:

• avoidance of the site; and

• detailed recording and mapping.

However, the visual effect will be assessed in the field, and site-specific mitigation measures will be refined and optimized, as warranted.

Sacred Areas Sacred areas include burials, vision quest locations, rock art panels, birth locations and ceremonial places, among others. A particular element is often only a small component of a larger spiritual complex, which can encompass topographic features and may, by its very nature in the context of Indigenous spirituality, be inestimable and irreplaceable.

Mitigation measures for sacred areas may include the following:

• avoidance of the site; and

• detailed recording and mapping.

Additional site-specific mitigation measures may be refined and optimized in the field and through community discussions, as warranted.

9.2 Traditional Land Use Sites Discovered During Construction

Possible indications that a location might be a previously unidentified TLU site may include the observation of manufactured materials or alteration of natural materials, which appear to be derived from the activities of traditional land users. In the event that previously unidentified TLU sites are identified during construction of the facility, the following measures will be implemented, as warranted.

• Flag or fence off the previously unidentified TLU site. Work within that location may not resume until the following measures are conducted. Notify an Environmental Inspector, who will notify the Construction Manager or designate, the Indigenous Monitor and the TLU Resource Specialist.

- The TLU Resource Specialist and the Indigenous Monitor will assess the site and develop an appropriate mitigation plan using the information from subsection 9.1.

- The potentially affected Indigenous group(s) will be informed of the discovery by Trans Mountain and the proposed mitigation measures to be implemented.

Page B-24

10.0 WET/THAWED SOILS CONTINGENCY PLAN Trans Mountain will assign Environmental Inspectors with sufficient training and soils-related experience to identify soils that are too wet for a particular activity and when the soils are sufficiently dry to allow the activity to resume. The decision to continue or suspend particular construction activities on lands with excessively wet/thawed soils will be made by the Construction Manager in consultation with an Environmental Inspector. A record of the location, timing and reason for implementation of the Wet/Thawed Soils Contingency Plan will be maintained by the Environmental Inspectors. In the event that activities are suspended, the Environmental Inspectors will notify the Senior Compliance Advisor as soon as practical, who will notify the CER, if warranted.

The Environmental Inspectors will be responsible for monitoring ground conditions and ensuring that all suitable protection measures are implemented. Trans Mountain believes that it is critical to maintain effective communication between the Contractor, the Environmental Inspectors and the regulators (i.e., the CER, via the Senior Compliance Advisor). A meeting will be held in the field to ensure that all parties involved mutually understand the concerns associated with working in wet/thawed conditions. Soils are considered to be excessively wet when the planned activity could cause: damage to soils either due to rutting by traffic through the surface material into the subsoil; soil structure damage during soil handling or; compaction and associated deformation of surface material due to heavy traffic.

Contingency measures will be implemented, if warranted, if one of the following indicators occurs:

• rutting of topsoil to the extent that admixing may occur;

• deformation of soil;

• excessive wheelslip;

• excessive build-up of mud on tires and cleats;

• formation of large puddles; and/or

• excessive tracking of mud as vehicles leave the facility.

Where construction activities have the potential to, or are causing the aforementioned issues, the Construction Manager, in consultation with an Environmental Inspector and the Contractor, will suspend that phase and/or area of the construction activity until soil conditions dry out/freeze, or effective mitigation procedures have been implemented.

Construction alternatives will be employed, when warranted, in the event of thawed soils during frozen conditions and/or an excessively wet surface during non-frozen conditions. The contingency measures listed as follows may be implemented individually or in combination, as necessary, based on site-specific conditions.

Wet Soil Contingency Measures • Temporarily modify or shut-down construction activities at the location with wet soil conditions until

the conditions improve; the decision to modify or shut-down construction will be made following a discussion involving the Contractor, the Construction Manager and an Environmental Inspector.

• Restrict construction traffic, where feasible, to equipment with balloon tires or wide pad tracks.

• Prevent rubber-tired traffic from driving on areas of the facility and associated components construction footprint with unsalvaged topsoil.

• Postpone work in highly sensitive areas and restrict work efforts to low sensitivity or non-problem areas (e.g., well-drained soils) until conditions improve. Install matting or equivalent in problem areas.

• Suspend construction activities and traffic in areas (outside of the development zone) with wet soil conditions until the soils dry out.

• Implement drainage controls (shallow ditching and/or pumping) to prevent puddling and expedite drying, where practical.


01-13283-GG-0000-CHE-RPT-0027

Page B-25

Resumption of suspended work at any given location must be authorized by the Construction Manager, in consultation with an Environmental Inspector once conditions are acceptable.

Thawed Soil Contingency Measures • Restrict construction traffic, where feasible, to equipment with low-ground-pressure tires or wide pad

tracks.

• Prevent rubber-tired traffic from driving on areas of the facility and associated components construction footprint.

• Restrict work to non-problem areas, such as frozen or well-drained soils, until conditions improve.

• Limit construction activities and traffic to the evening or early morning when the ground is frozen, if thawed ground conditions are encountered.

• Install matting or equivalent in problem areas.

• Employ frost inducement measures (e.g., snow packing or plowing) to increase the load-bearing capacity of thawed ground as a temporary measure.

• Suspend construction activities and traffic in areas with thawed soils until the soils dry out or re-freeze.

If the indicators of excessively wet/thawed soil conditions previously noted above are not evident, soils will be considered dry enough to resume activity.

Partial Suspension of Construction Activities and Traffic The primary concern during wet/thawed soil conditions is the potential for rutting, compaction and loss of soil structure (deformation) of the topsoil. Depending upon the land use and width of topsoil salvage conducted, some construction activities may be conducted, and traffic allowed to travel during wet/thawed soil conditions while others are suspended. Criteria to be used in determining how to mitigate for wet or thawed soil conditions or allow for a mutual decision by the Contractor, Construction Manager and the Environmental Inspector(s) to suspend activities until soils dry out are provided in Table B-2.

11.0 WILDLIFE SPECIES OF CONCERN ENCOUNTER AND DISCOVERY CONTINGENCY PLAN

11.1 Wildlife Discovery

The following procedures provide contingency measures for wildlife discovery. A wildlife species at risk refers to wildlife species listed as Special Concern, Threatened or Endangered Federally on Schedule 1 of the Species at Risk Act (SARA) and/or by Committee on the Status of Endangered Wildlife in Canada, and are Red- or Blue-listed in BC or listed under the Alberta or BC Wildlife Acts. Species of Concern refers to wildlife species that have increased potential to be affected by Project activities due to spatial or temporal overlap with the Project during sensitive life stages and therefore may have identified setbacks and timing windows.

Wildlife Species at Risk or Species of Concern Discovery Prior to Clearing/Construction In the event that wildlife species at risk or species of concern or their site-specific habitat feature is discovered during wildlife or other studies of the facilities footprint or other associated components (e.g., storage sites), the discovery will be assessed and appropriate mitigation measures will be determined by a Wildlife Resource Specialist in consultation with an Environmental Inspector and the Construction Manager or designate. The review of the wildlife species observation or habitat feature will consider the following:

• The wildlife species, its conservation status and specific habitat needs relative to the area of development.

• The location of the wildlife habitat feature (e.g., stick nest) relative to the area of development and in consideration of the recommended setback distances as provided by regulatory guidelines, where applicable.

• The presence of topographic features or vegetation to effectively screen the wildlife habitat feature from construction activities.

• The timing of construction versus the timing windows/sensitive periods for the wildlife species as provided by regulatory guidelines, where applicable.

• The potential for an alteration of construction activities to reduce or avoid direct and/or sensory disturbance.

The mitigation measures to be implemented will be determined by a qualified Wildlife Resource Specialist and may include the following:

• Abide by seasonal timing windows and the recommended setback distances as provided by regulatory guidelines, where feasible.

• Abide by daily timing restrictions on construction activities, where feasible.

• Reduce the area of disturbance and protect the site using fencing or clearly mark the site using flagging.

• Inform all users of access restrictions in the vicinity of flagged or fenced sites.

• Ensure the appropriate Provincial permit is obtained for the salvage and relocation of wildlife species or the removal of a nest protected by the BC Wildlife Act. Note that habitat enhancement measures or a replacement nest may be needed dependent on the conditions of the permit. Ensure that a SARA Section 73 Permit is obtained on Federal lands (e.g., Indian Reserves), if the Project will affect species listed as Extirpated, Endangered or Threatened on Schedule 1 of SARA and will contravene SARA’s general or Critical Habitat prohibitions (i.e., no person will kill, harm, harass, capture or take a wildlife species; damage or destroy the residence of one or more individuals of a wildlife species; or destroy any part of the Critical Habitat of any Endangered, Threatened or Extirpated species).

The locations of important wildlife and wildlife habitat encountered and appropriate mitigation to be implemented are identified in the Resource-Specific Mitigation Table and Environmental Facility Drawings provided in Appendices D and E of the Facilities EPP, respectively.

Wildlife Species at Risk or Species of Concern Discovery During Clearing/Construction Wildlife species at risk or species of concern and their habitat that have the potential to occur near the Project Footprint, as well as the locations of Provincially-identified wildlife areas (e.g., Key Wildlife and Biodiversity Zones, and Ungulate Winter Ranges) will be communicated to Project personnel through the Environmental and Compliance Education Program. The Contractors will be provided with detailed information on identifying wildlife species risk or species of concern and their site-specific habitats.

In the event of an observation of a wildlife species at risk or species of concern, the mitigation will vary depending on the species. For example, observations of song birds and/or large mammals, where no associated habitat feature (e.g., active nest or mammal den) is present, may not warrant mitigation given their ability to move away from the construction area. For other species (e.g., amphibians that may be restricted to a discrete area), mitigation measures (e.g., salvage of individuals in compliance with the appropriate permit) will be reviewed and implemented as required.

If wildlife species at risk or species of concern or their site-specific habitat is discovered during clearing/construction, the discovery will be assessed and appropriate mitigation measures will be determined. Upon discovery the following will occur.

• Suspend work immediately in the vicinity of any newly discovered wildlife species at risk or species of concern. Do not resume work at that location until the measures below are implemented.

• Notify an Environmental Inspector who will complete the appropriate record-keeping/reporting and notify the Construction Manager.

• The Lead Environmental Inspector will assess the discovery and either allow construction to resume or, in the event of a confirmed or potential discovery, proceed by notifying the following:

Trans Mountain’s Regulatory and Compliance Team; and

a Wildlife Resource Specialist.

• A qualified Wildlife Resource Specialist will assess the discovery and determine the appropriate mitigation measures to be implemented in consultation with an Environmental Inspector, the Construction Manager and the Appropriate Government Authority. The Wildlife Resource Specialist will visit the site, if warranted.

11.1.1 Wildlife Encounter Contingency Plan

In the event of an encounter with wildlife during construction either at the construction site or on the commute to and from the construction site, follow the measures provided as follows.

• Report any incidents (e.g., aggressive behaviour, nuisance behaviour, obtained food or garbage) with wildlife to an Environmental Inspector who will complete the appropriate record-keeping/reporting and immediately notify the Senior Compliance Advisor. The Senior Compliance Advisor will notify the Appropriate Government Authority and, if warranted, the local Fish and Wildlife detachment (Appendix A of the Facilities EPP).

• Report any trapped, injured or dead animals on-site to an Environmental Inspector who, if warranted, will notify Trans Mountain’s Regulatory and Compliance Team so the Appropriate Government Authority can be contacted to consult on appropriate action.

• Report the location and details of collisions with wildlife to an Environmental Inspector, who will notify the Appropriate Government Authority and, if warranted, the local conservation officer, if applicable (Appendix A of the Facilities EPP).

Notes:

1. Install sediment fences, where warranted, to minimize the transfer of sediment from spoil windrows and stripped areas to watercourses/wetlands.

2. Ensure sediment fence is keyed into the ground by establishing a narrow trench, placing the base of the sediment fence in the trench and backfilling the trench, which secures the sediment fence in place.

3. Install the posts (e.g., wood/metal posts) on the downhill facing side so the runoff pushes the fabric against the post 4. When installing multiple lengths of sediment fencing end to end, overlap the ends a minimum of 18-inches or two wood post

lengths (if sediment fencing is in a roll). 5. Maintain sediment fences throughout construction. 6. If sediment loading exceeds two-thirds the height of the sediment fencing, the sediment shall be removed. 7. Ensure that sediment fences, if removed or damaged, are reinstalled or repaired prior to the end of the work day. 8. Remove temporary sediment fences after the disturbed area is reclaimed and construct permanent sediment controls in their

place if warranted.

Rare Plants/Weeds/Timber Wetlands Watercourses Soils Reclamation Archaeology TLU/TLRU Sumas Terminal KP 1114.95 to KP 1115.10 a-079-B/092-G-01

The Sumas Terminal is located at a-079-B/092-G-01. Proposed Project activities include an expansion of facility boundaries to the north on forested lands acquired by Trans Mountain prior to construction. Current land use within the existing station property boundaries is previously disturbed industrial lands. The proposed activities are within the existing Sumas Terminal property boundary; however, the existing fence line will be moved along the northern and southern boundaries resulting in approximately 2.75 ha of new disturbance.

No site-specific wildlife concerns identified. Initiate clearing and construction activities outside of the migratory bird nesting period (March 26 to August 16), where feasible. Refer to mitigation measures for migratory birds provided in Section 6.0 of the Facilities EPP. In the event amphibian (i.e., long-toed salamander, northern red-legged frog, Pacific tree frog, western toad) or small mammal (i.e., Olympic shrew, Pacific water shrew, Trowbridge’s shrew) are encountered in the work area a salvage may be necessary. Consult with an Environmental Inspector to determine the need for a salvage. Any relocation of wildlife will be conducted by a Wildlife Resource Specialist and salvages will comply with permit conditions.

During site assessments on March 6, 2018 and March 4, 2019 the forest to the north, east, and west of the existing facility was determined to be the rare ecological community Western redcedar – foamflower (Thuja plicata - Tiarella trifoliata, S2S3, Blue-listed). The forest to the south was determined to be the rare ecological community western redcedar – sitka spruce/skunk cabbage (Thuja plicata – Picea sitchensis / Lysichiton americanus, S3?, Blue-listed). The 10-15 m of dense Himalayan blackberry around the existing fence line are not part of these rare ecological communities. No mitigation is recommended for these Blue-listed ecological communities because cleared areas will not be reclaimed following construction. All clearing around the existing terminal is located within an Early Draft Critical Habitat polygon for Roell’s brotherella moss (Environment Canada 2014). The extent of Early Draft Critical Habitat is not publicly available and is provided with the permission of Environment and Climate Change Canada. The forested areas within 30 m of watercourses are considered locations of interest that possesses the ecological attributes required for Roell’s brotherella moss. Within these areas, a Resource Specialist should screen for Roell’s brotherella moss pre-disturbance. If Roell’s brotherella moss is located on the workspace, re-locate its substrate to a suitable habitat in the immediate vicinity of the Project. The location (e.g., aspect and vertical position) and habitat (e.g., substrate, light and humidity conditions) of the receiving sites will emulate conditions, including the substrate types that occurred in the critical function zone at the transplant source location, to the extent feasible. Japanese knotweed and wild chervil are known to occur at the Sumas Terminal. Himalayan blackberry occurs around the existing fence line. Ensure all vehicles will arrive and leave the site clean of soil and debris to prevent the transfer of weeds. Refer to mitigation measures for weeds provided in Section 6.0 of the Facilities EPP in the event that weeds are encountered during construction. Timber disposal – no burning.

A portion of a needle-leaf treed swamp (Sumas_WT_1) within the south portion of the expansion area may potentially be permanently disturbed by construction activities. Ensure approvals under Section 11 of the Water Sustainability Act are in place prior to construction, as required. Comply with all approval Conditions. A needle-leaf treed swamp (Sumas_WT_2) is located adjacent to the expansion area, however the wetland will not be directly disturbed. There is an artificial pond (WT-1606) located at the east side of the pump station that may be directly or indirectly affected by construction activities. Consult with an Environmental Inspector regarding water management options in artificial ponds.

Eight watercourses are located within the expansion area: Unnamed channel; BC785a3/WC1 (S6) Vernal Pool; WC6 WC1A (NCD) WC1B (NCD).

Rare Plants/Weeds/Timber Wetlands Watercourses Soils Reclamation Archaeology TLU/TLRU Burnaby Terminal KP 1179.95 to KP 1180.147 a-025-D/092-G-07

The Burnaby Terminal is located within the Municipal boundaries of the City of Burnaby. All Project activities will occur on lands owned by Trans Mountain. Most land within existing terminal boundaries has been previously disturbed; however, the southwest corner contains treed land and artificial ponds are located in the northeast and southwest corners.

Initiate clearing and construction activities outside of the migratory bird nesting period (March 26 to August 16), where feasible. Refer to mitigation measures for migratory birds provided in Section 6.0 of the Facilities EPP. The red-tailed hawk nest that was located adjacent to the Burnaby Terminal has been removed (i.e., when the nest was not occupied), therefore mitigation for this feature is no longer necessary. A portion of the terminal is located within Proposed Critical Habitat for western painted turtle. Refer to the western painted turtle section for applicable measures (Appendix A of CER Condition 92: Updates Under the Species at Risk Act). Prior to Project clearing and construction, an amphibian survey and salvage will be conducted to ensure that any amphibians within the Burnaby Terminal property will not be harmed by Project activity. A Qualified Professional (i.e., Wildlife Resource Specialist) will be on-site to conduct an amphibian survey and re-locate amphibians out of the active work site. This work will be done in a manner consistent with the provincial amphibian salvage permit and Best Management Practices for Amphibian and Reptile Salvages in British Columbia (BC MFLNRO 2016). In the event that active barn swallow nests are found during Project activity, the appropriate mitigation will be selected by an Environmental Inspector in consultation with a Wildlife Resource Specialist (e.g., species-specific buffer or non-intrusive monitoring).

A Roell’s brotherella moss Early Draft Critical Habitat polygon intersects the footprint of the Burnaby Storage Terminal. Refer to the Rare Ecological Community and Rare Plant Population Management section provided in Section 5.3 of Volume 6 of the Environmental Plans for mitigation measures. Himalayan blackberry, common tansy, scotch broom, English holly, purple loosestrife, cutleaf blackberry, orange hawkweed, field bindweed and English ivy have been recorded at the Burnaby Terminal. Ensure all vehicles will arrive and leave the site clean of soil and debris to prevent the transfer of weeds. Refer to mitigation measures for weeds provided in Section 6.0 of the Facilities EPP in the event that weeds are encountered during construction. Timber disposal – no burning. The following will be implemented at Burnaby Terminal to prevent the spread of weeds: • Cut or mow standing vegetation on the site; • Dispose of cut or mowed vegetation that

contains seed, and blackberry root fragments disturbed during vegetation removal or soil disturbance, at a landfill that accepts invasive plants, or bury the material at a depth that will prevent weeds from growing and spreading;

• Avoid moving soils off-site. Surface soils (upper 15 cm) from infested areas may be buried on-site at a depth that will prevent weeds from growing and spreading. If soils must be moved off-site, ensure they are disposed of at a facility that accepts weed infested soils.

No wetlands present. There are two artificial ponds located at the northeast (WT-1605) and southwest (WT-814) corners of the pump station that may be directly or indirectly affected by construction activities. Consult with an Environmental Inspector regarding water management options in artificial ponds.

Six watercourses are located within the expansion area: Unnamed Channel; BC-785a3 (S5) Unnamed Drainage; BC-785b (NCD) Unnamed Drainage; BC-785c (NCD) Unnamed Drainage; BC-785h (NCD) Unnamed Drainage; BC-785i (NCD) Unnamed Channel; BC-785j (S6) Ensure approvals under Section 11 of the Water Sustainability Act are in place prior to diversion, as required. Comply with all approval Conditions.

No topsoil salvage is required in areas of disturbed land. If off-site movement of salvaged topsoil or subsoil is required, adhere to Conditions specified in the applicable permits.


Archaeological monitoring or Archaeological Impact Assessment is recommended in areas with moderate to high potential for buried archaeological resource. Consult with a Heritage Resource Specialist to confirm monitoring locations if required.

The forest to the south was determined to be the rareecological community western redcedar – sitka spruce/skunk cabbage (Thuja plicata – P icea sitchensis / Lysichiton americanus, S3?, Blue-listed). The 10-15 m ofdense Himalayan blackberry around the ex isting fence line are not part of these rare ecological communities.No mitigation is recommended for these Blue-listed ecological communities because cleared areas will not be reclaimed following construction.All clearing around the ex isting terminal is located within an Early Draft Critical Habitat polygon for Roell’s brotherella moss (Environment Canada 2014). Theex tent of Early Draft Critical Habitat is not publicly available and is provided with the permission of Environment and Climate Change Canada.The forested areas within 30 m of watercourses are considered locations of interest that possesses the ecological attributes required for Roell’s brotherella moss.W ithin these areas, a R esource S pecialist should screen for R oell’s brotherella moss pre-disturbance. If Roell’s brotherella moss is located on the workspace, re-locate its substrate to a suitable habitat in the immediate vicinity of the P roject. The location (e.g., aspect and vertical position) and habitat (e.g., substrate, lightand humidity conditions) of the receiving sites will emulate conditions, including the substrate ty pes that occurred in the critical function zone at the transplantsource location, to the ex tent feasible.Japanese knotweed and wild chervil are known to occur at the S umas Terminal.

General Information:The Burnaby Terminal is located within the Municipal boundaries of the City of Burnaby. All Project activities will occur on lands owned by Trans Mountain. Most landwithin existing terminal boundaries has been previously disturbed; however, the southwest corner contains treed land and artificial ponds are located in the northeastand southwest corners.

Archaeology:Archaeological monitoring or Archaeological Impact Assessment is recommended in areas with moderate to high potential for buried archaeological resource. Consultwith a Heritage Resource Specialist to confirm monitoring locations if required.

Reclamation:Seed temporarily disturbed areas with the following seed mix at the prescribed rate.Turf-type tall fescue – 40%Hard fescue – 40%Turf-type perennial ryegrass – 20%

Broadcast seeding rate: 25 kg/haDrill seeding rate: 10 kg/haHydroseeding: 50 to 75 kg/haIn areas with ongoing maintenance constraints (e.g., high slopes, or where access for vegetation maintenance is restricted), an alternative seed mix with low growthplants may be warranted. Consult with an Environmental Inspector to confirm the appropriate seed mix and suitable locations.

Soils:No topsoil salvage is required in areas of disturbed land.If off-site movement of salvaged topsoil or subsoil is required, adhere to Conditions specified in the applicablepermits.

Vegetation - Rare Plants / Weeds / Timber:A Roell’s brotherella moss Early Draft Critical Habitat polygon intersects the footprint of the Burnaby Storage Terminal. Refer to the Rare Ecological Community andRare Plant Population Management section provided in Section 5.3 of Volume 6 of the Environmental Plans for mitigation measures.Himalayan blackberry, commontansy, scotch broom, English holly, purple loosestrife, cutleaf blackberry, orange hawkweed, field bindweed and English ivy have been recorded at the BurnabyTerminal.Ensure all vehicles will arrive and leave the site clean of soil and debris to prevent the transfer of weeds. Refer to mitigation measures for weeds provided inSection 6.0 of the Facilities EPP in the event that weeds are encountered during construction.Timber disposal – no burning.The following will be implemented at Burnaby Terminal to prevent the spread of weeds:·Cut or mow standing vegetation on the site;·Dispose of cut or mowed vegetation that contains seed, and blackberry root fragments disturbed during vegetation removal or soil disturbance, at a landfill that

accepts invasive plants, or bury the material at a depth that will prevent weeds from growing and spreading;·Avoid moving soils off-site. Surface soils (upper 15 cm) from infested areas may be buried on-site at a depth that will prevent weeds from growing and spreading. If soils must be moved off-site, ensure they are disposed of at a facility that accepts weed infested soils.

Watercourses and Fish Habitat:Six watercourses are located within the expansion area:Unnamed Channel; BC-785a3 (S5)Unnamed Drainage; BC-785b (NCD)Unnamed Drainage; BC-785c (NCD)Unnamed Drainage; BC-785h (NCD)Unnamed Drainage; BC-785i (NCD)Unnamed Channel; BC-785j (S6)Ensure approvals under Section 11 of the Water Sustainability Act are in place prior to diversion, as required. Comply with all approval Conditions.

Wetlands:No wetlands present.There are two artificial ponds located at the northeast (WT-1605) and southwest (WT‑814) corners of the pump station that may be directly or indirectly affected byconstruction activities. Consult with an Environmental Inspector regarding water management options in artificial ponds.

Wildlife:Initiate clearing and construction activities outside of the migratory bird nesting period (March 26 to August 16), where feasible. Refer to mitigation measures formigratory birds provided in Section 6.0 of the Facilities EPP.The red-tailed hawk nest that was located adjacent to the Burnaby Terminal has been removed (i.e., when the nest was not occupied), therefore mitigation for thisfeature is no longer necessary.A portion of the terminal is located within Proposed Critical Habitat for western painted turtle. Refer to the western painted turtle sectionfor applicable measures (Appendix A of CER Condition 92: Updates Under the Species at Risk Act).Prior to Project clearing and construction, an amphibian surveyand salvage will be conducted to ensure that any amphibians within the Burnaby Terminal property will not be harmed by Project activity. A Qualified Professional (i.e.,Wildlife Resource Specialist) will be on-site to conduct an amphibian survey and re-locate amphibians out of the active work site. This work will be done in a mannerconsistent with the provincial amphibian salvage permit and Best Management Practices for Amphibian and Reptile Salvages in British Columbia (BC MFLNRO2016).In the event that active barn swallow nests are found during Project activity, the appropriate mitigation will be selected by an Environmental Inspector inconsultation with a Wildlife Resource Specialist (e.g., species-specific buffer or non-intrusive monitoring).

CONSULTATION AND ENGAGEMENT

Consultation and engagement activities related to the mitigation measures in the Facilities Environmental Protection Plan (Facilities EPP) were completed with Appropriate Government Authorities, potentially affected Indigenous groups and affected landowners/tenants. Opportunities to discuss the mitigation measures and identify issues or concerns were also provided to public stakeholders during meetings, workshops and ongoing engagement activities.

Consultation and engagement opportunities began in May 2012 with the Trans Mountain Expansion Project (TMEP or the Project) announcement and are ongoing.

1.0 CONSULTATION AND ENGAGEMENT OVERVIEW: DRAFT PLAN DEVELOPMENT

Reports on activities completed between May 2012 and June 30, 2015 were filed with the Canada Energy Regulator (CER) and are available in the Application (Volume 3A: Stakeholder and Volume 3B: Indigenous; Filing ID A55987) as well as in Consultation Update No. 1 and Errata, Technical Update No. 1 (Filing ID A59343) , Consultation Update 2 (Filing IDs A62087 and A62088), Consultation Update 3 (Filing IDs A4H1W2 through A4H1W8) and Consultation Update 4 (Filing ID A72224). These reports the results of consultation conducted to June 30, 2015, identification of issues and concerns as well as Trans Mountain’s response are included as follows.

Consultation and engagement activities completed between July 1, 2015 and March 2017 have not been filed on the public record with the CER. Any new issues, concerns regarding mitigation measures identified during this period, as well as Trans Mountain Pipeline ULC’s (Trans Mountain’s) response, are also described as follows.

Kel Mae Coulson, Chevron Westridge Marine Terminal/ Burnaby Terminal Workshops

November 24, 2016 Consider watercourse connectivity through Burnaby Terminal: Has any thought been given to connecting the fish streams above and below to create a new fish-bearing stream? Recommendation that TMEP review the City’s “Integrated storm water management plan” available online

No records of documented fish presence in watercourses above the Burnaby Terminal (i.e., that flow through or connect to watercourses within the Burnaby Terminal) have been found. Based on the seasonal nature of flows within Eagle Creek, and the presence of a significant barrier to fishes at Shellmont Street and Arden Avenue, Eagle Creek is considered non-fish-bearing in its reaches upstream from Shellmont Street. Given these factors, exploring projects to increase the connectivity and fish passage in these streams (particularly Eagle Creek) is not justified. TMEP will review the City’s plan.

John Templeton, Stoney Creek Westridge Marine Terminal/ Burnaby Terminal Workshops

November 24, 2016 Consider making water quality information available to the public in a similar manner to air quality monitoring information

Trans Mountain will review options for making water quality monitoring data available to the public. Water quality data collected during construction is required to be submitted to regulators following construction, thus is available within the public domain (i.e., CER website).

Nick Kvenich, Eagle Creek Information session

January 4, 2017 Would like to see streams at the Burnaby Terminal daylighted

Trans Mountain has reviewed this request from the Eagle Creek Streamkeepers in conjunction with plans for the increased tank capacity within the Burnaby Terminal. No additional daylighting of watercourses within the Terminal facility is feasible. Sections currently below ground in culverts are to remain culverted.

Nick Kvenich, Eagle Creek Meeting with streamkeepers

December 15, 2016 Does Trans Mountain have plans to put streams at Burnaby Terminal that open now into the pipe? It's important to keep open. Open ditch is better for us - aeration. Don't want to see things underground. Can you divert the creek outside the fence?

Trans Mountain is proposing to direct an additional section of the tributary to Eagle Creek into a new culvert. A number of non-classified drainages will also have flows directed into new sections of culvert. Trans mountain did investigate the option of diverting flows outside the Terminal facility; however, given the difficulties with obtaining the necessary consents, difficulties in diverting flows from one watershed (Eagle Creek) and into another (Silver Creek) and then bringing flows back, this was not explored further.

Note: * Attended EPP Workshop

3.2 Indigenous Group Engagement

Since April 2012, Trans Mountain has engaged with Indigenous groups who might have an interest in the Project or have Indigenous interests potentially affected by the Project, based on the proximity of their community and their assertion of traditional and cultural use of the land along the pipeline corridor to maintain a traditional lifestyle. The objectives of Indigenous engagement are to:

• have an open, transparent and inclusive process that seeks to exchange information in a respectful manner;

• address concerns shared by those who might have an interest in the Project or have Indigenous interests potentially affected by the Project;

• incorporate feedback into Project planning and execution; and

• provide opportunities to maximize Project benefits to Indigenous groups.

Trans Mountain prepared the Heritage Resources and Sacred and Cultural Sites Plan to satisfy CER Condition 100 (Filing ID A6Y0U2) which provides a list of sacred and cultural sites identified within 1 km of the Project, including access roads and temporary construction lands and infrastructure sites. Site-specific information outside of 1 km was considered; however, as the Facilities EPP addresses resources on the Project Footprint, no specific mitigation was or could be employed for sites well outside of the disturbance area.

Appendix 8 of the CER reconsideration of aspects of its OH-001-2014 Report as directed by Order in Council P.C. 2018-1177 MH-052-2018 (Filing ID A6S2D8) identifies the sources of information provided by Indigenous intervenors and commenters in the OH-001-2014 hearing, and Indigenous intervenors in the MH-052-2018 hearing. This information, along with information contained in the outcomes of Phase III Crown consultation, the permitting process and consultation logs were reviewed to understand specific interactions between sacred and cultural sites and the Project. Information shared by Indigenous groups during Phase III Crown consultation about sacred and cultural sites already addressed in the OH-001-2014 proceeding or in Condition 97 were not included in the Condition 100 update.


https://apps.cer-rec.gc.ca/REGDOCS/Search?dn=A6S2D8


01-13283-GG-0000-CHE-RPT-0027

Page F-6

Sacred and cultural sites identified in the OH-001-2014 proceeding, MH-052-2018 Reconsideration proceeding, or Phase III Crown consultations, and not already captured under Condition 97 are outlined in Condition 100 (Filing ID A6Y0U2). Some Indigenous groups provided Trans Mountain sacred and cultural site information confidentially. These sites are not included in Condition 100. Confidential information has been received from Asini Wachi Nehiyawak (Mountain Cree Traditional Band), Coldwater Indian Band, Ditidaht First Nation, Foothills Ojibway First Nation, Kwikwetlem First Nation, Maa-Nulth Treaty Society, Nicomen Indian Band, Nooaitch Indian Band, Shackan Indian Band, Simpcw First Nation, Squamish Nation, Stk’emlupsemc te Secwepemc of the Secwepemc Nation and Tsleil-Waututh Nation. Trans Mountain will work with Indigenous groups to mitigate confidential Traditional Land Use (TLU) sites and implement recommended mitigation, where practicable, using the process outlined in Condition 100. Indigenous engagement is ongoing and new information will be incorporated into construction planning.

A comprehensive Indigenous group engagement process is led by experienced Engagement Advisors in Alberta and BC, specialized in the areas of Indigenous relations, law, economic development, education, training, employment and procurement. Trans Mountain’s engagement process for the Project is flexible, allowing each community and group to engage in meaningful dialogue in the manner they choose and in a way to meet their objectives and values.

Each community had the opportunity to engage with Trans Mountain, depending upon Project interests and potential effects. The following opportunities to engage have been provided:

• Project announcement;

• initial contact with Indigenous group;

• meetings with Chief and Council and meetings with staff;

• host community information session(s);

• conduct TLU studies and socio-economic interviews;

• identify interests and concerns; and

• identify mitigation options.

Issues and concerns related to the Facilities EPP raised during Indigenous engagement from between early 2012 to March 2017 are summarized in Table F-2.

SUMMARY OF INDIGENOUS CONCERNS REGARDING THE FACILITIES EPP

Issue or Concern

Summary Trans Mountain Response Where Addressed Summary Indigenous

Group Concerns regarding about the ability of Trans Mountain and its contractors to respond to and mitigate damage in a timely manner in the event of a pipeline spill, leak or rupture particularly at the Sumas Mountain Terminal. Consider a minimum spill response time included in the Spill Contingency Plan in terms of initiating the clean-up of a spill, be it associated with construction, the existing Trans Mountain Pipeline (TMPL), or a third-party pipeline.

Shxw’ōwhámel First Nation Halalt First Nation

Construction Phase To comply with the systematic Safety Management Program approach outlined in Section 47 of the Canadian Energy Regulator Onshore Pipeline Regulations (CER OPR), an Emergency Response Plan (ERP) will be developed and implemented for TMEP construction. The TMEP construction ERP will be separate from, and complementary to, the Trans Mountain Operations ERP and will lay out the guidelines for the development of the Contractors’ detailed site-specific ERPs. The TMEP construction ERP will address legislative requirements and will be based on recognized industry standards of practice. The Spill Contingency Plan in the Facilities EPP is not intended to address spills during operations and is not the appropriate place to address spill response times. Operations Phase CER Condition 119 (Emergency Preparedness and Response Exercise and Training Program) requires Trans Mountain to file with the CER, at least 1 year prior to commencing operations, an Emergency Preparedness and Response Exercise and Training Program for the pipeline; the Edmonton, Sumas and Burnaby Terminals; and the Westridge Marine Terminal. The program’s objective is to demonstrate the continual improvement of responder competencies (including control centre personnel) at all levels of the company to prepare for, respond to, recover from, and mitigate the potential effects of emergencies of any type, including tank fires and earthquakes. CER Condition 125 (ERPs for the Pipeline and for the Edmonton, Sumas and Burnaby Terminals) requires with the Trans Mountain to file with the CER, at least 6 months prior to commencing operations, updated ERPs for the Edmonton, Sumas and Burnaby Terminals, which will include an ERP to include the pipeline expansion.

Issue or Concern


Group Concerns regarding the potential for seismic activity and the effect it could have on all aspects of the Project including equipment failure at Burnaby Mountain Terminal resulting in effects to Squamish Nation including its rights and title.

Squamish Nation

CER Condition 68 (Seismic Reports – Liquefaction Potential) requires Trans Mountain to file with the CER, at least 3 months prior to commencing construction, a final report that identifies all sites along the Project, that have “Very High,” “High,” and “Moderate” liquefaction-triggered ground movement potential, and that describes how the potential for liquefaction-triggered ground movement will be mitigated at each site. CER Condition 69 (Fault Studies) requires Trans Mountain to file with the CER, at least 3 months prior to commencing construction, the results of fault-mapping studies that were ongoing during or undertaken after the OH-001-2014 proceeding, for use in the detailed design of the Project. This filing must include conclusions regarding possible seismic activity during the Holocene epoch for Sumas Fault, Vedder Mountain Fault, Fraser River-Straight Creek Fault and Rocky Mountain Trench, and other possible hidden faults, as well as the potential for compounding risks due to the proximity of the Vedder Mountain and Sumas Faults.

CER Condition 68 (Seismic Reports – Liquefaction Potential) CER Condition 69 (Fault Studies)

Cultural Training and Consideration (Section 4: Compliance) In the area of compliance, Halalt First Nation would like to see increased commitment to both Indigenous Participation and Cultural Training throughout the Compliance process. To that end, we would like to see: • The inclusion of training on Indigenous values in

Level 1 of the Environmental and Compliance Training Program so that all employees are able to identify key areas of high indigenous value

• The amendment of the Environmental Inspector's qualifications to include experience working with Indigenous groups

• A commitment to a clear number or ration of Indigenous Monitors in relation to the total project areas and total Inspectors.

Halalt Environmental Training requirements have been updated and moved to the Project ECMP (Volume 10 of the Environmental Plans).

ECMP (Volume 10 of the Environmental Plans)

MOC (Section 4: Compliance) Halalt First Nation would like to see a commitment to engagement and consultation with Indigenous groups should any changes to management occurs.

Halalt The Project has defined Roles and Responsibilities within the ECMP (Volume 10 of the Environmental Plans) for environmental personnel. CER Condition 88 requires Trans Mountain file the Project Organizational Structure for Project Construction 2 months prior to starting construction and CER Condition 96 requires reports on engagement with Indigenous groups. Trans Mountain will not commit to engage communities regarding personnel changes; however, existing CER Conditions that require engagement with Indigenous groups will apply regardless of who is managing the Project.

ECMP (Volume 10 of the Environmental Plans)

Flagging (Section 7: General Provisions) Halalt First Nation would like to encourage the proponent to ensure that Indigenous individuals from proximal communities are included in flagging key features along the Project corridor to ensure that any important features that are highly valued by those communities have the opportunity to be flagged

Halalt Appendix 1 of the ECMP outlines the Roles and Responsibilities of the Indigenous Monitor, which include working with the Environmental Inspector to ensure the protection of environmental and heritage resources.

Issue or Concern


Group Use of Wetlands (Section 11: Hydrostatic Testing) Halalt First Nation would like to see more robust language around the assessment of whether or not using water from a wetland for hydrostatic testing would impact the environmental functions of that ecosystem.

Halalt Trans Mountain will abide by all permit conditions for hydrostatic testing. Additional information on water withdrawal criteria can be found in the Water Withdrawal and Discharge Management Plan (Section 8.6 of Volume 6 of the Environmental Plans).

Section 3.0 of the Water Withdrawal and Discharge Management Plan (Section 8.6 of Volume 6 of the Environmental Plans)

Contaminated Site Resource Specialists (Appendix B: Contaminated Site Contingency Plan) Halalt First Nation would like this plan to include a list of proximal Contaminated Site Resource Specialists along the Project corridor and a minimum response time for those Specialists to arrive at an unforeseen contaminated site.

Halalt The Project’s approach to historical contamination is guided by the NEB’s Remediation Process Guide and the Contamination Identification and Assessment Plan (Section 3.2 of Volume 6 of the Environmental Plans). This suggestion has not been incorporated, since the current contingency plan as written allows for flexibility in the field without compromising safety.

N/A

TMEP has not provided funding for Katzie First Nation (KFN) to complete a TLU so the information collected and referred to in the draft plan is deficient with KFN territory. There appears to be no comments or discussion regarding eliminating impacts to potential wapato or cranberry bog areas that are critical to KFN from a TLU perspective. Notification of Interested parties should also provide sufficient time to land changes to traditional hunting and gathering activities; the construction needs to accommodate the KFN activities where they are limited due to seasonality of the resource; and the posting/notification needs to be for the whole corridor within the territory, not just in the vicinity of the community as indicated; Seeding and seed quality; Seeding and planting for erosion control and reclamation must use native plant species only.

Katzie Funding for a Traditional Land and Resource Use study has been discussed but the parties have been unable to reach agreement. Independent, third-party Cultural Background Report was filed as confidential evidence with the CER. Wapato (Sagittaria latifolia var latifolia) is discussed in the ITK section of the Burnaby to Westridge Segment of the Vegetation Technical Report (Volume 5C of the Environmental and Socio-Economic Assessment). Wapato was not observed during the vegetation surveys in 2013. A related species, arum-leaved arrowhead (Sagittaria cuneata), was observed during the 2013 surveys on the Black Pines to Hope Segment of the route. Bog cranberry (Vaccinium oxycoccos) was observed in 2013 on the Hargreaves to Darfield segment of the route. Mitigation measures for wetland crossings to reduce disturbance and restore wetland function is presented in the Wetland Survey and Mitigation Plan (Section 7.1 of Volume 6 of the Environmental Plans). Trans Mountain will provide the schedule and route maps a minimum of 4 weeks prior to the commencement of construction in the vicinity as outlined in Section 5.0 of the Facilities EPP. Reclamation and seeding will be conducted as outlined in the Reclamation Management Plan (Section 9.0 of the Environmental Plans).

Trans Mountain continues to liaise with Indigenous and Northern Affairs Canada, the Government of Canada’s Major Projects Management Office, the BC Ministry of Aboriginal Relations and Reconciliation and the Alberta Ministry of Aboriginal Affairs to provide updates regarding Trans Mountain’s engagement activities with Indigenous groups.

3.2.1 Identifying Indigenous Groups for Consultation

Trans Mountain used the First Nations Consultative Area Database Public Map Service to identify the Indigenous groups with traditional territories encountered by the Project facilities. Appendix G of the Facilities EPP lists the Indigenous groups identified for consultation.

3.2.2 Consultation Activities

A letter was sent to the Indigenous groups listed in Appendix G with a copy of the Draft Facilities EPP. Where appropriate and upon request, a follow-up meeting was arranged to discuss this Facilities EPP in more detail and address any concerns.

Trans Mountain has summarized the feedback received through Trans Mountain’s engagement on this Facilities EPP in Table F-2 and the summary includes how Trans Mountain responded to and addressed the concern or issue. It should be noted that although the engagement process also provided for opportunity for general discussion about Project construction and associated Indigenous issues and opportunities, only feedback/issues directly related to construction mitigation measures will be provided in this Facilities EPP. Other issues and topics raised have been captured in the corresponding mitigation plan, as appropriate.

3.3 Landowners/Tenants

Trans Mountain has implemented a comprehensive landowner engagement process for the TMEP to:

• ensure landowners are informed of the Project and how it may affect them;

• enable landowners to gain an understanding of their rights under the Canadian Energy Regulator Act (CER Act), and the regulatory process and their opportunities for comment within the CER regulatory process; and

• have a number of opportunities to discuss the Project, identify any concerns or questions they may have with the Project and have those questions and concerns addressed by Trans Mountain.

In addition to these opportunities for engagement, Trans Mountain is required to provide formal notifications of landowners under Sections 87 and 34 of the CER Act, and Trans Mountain has or will, at the appropriate time, provide such notices.

Individual landowners and tenants have different preferences with respect to communications, and Trans Mountain tailors its communications as requested. Land representatives working for Trans Mountain have been in discussions with landowners for over 3 years and issues or concerns raised with land agents have been documented in the Project landowner database, addressed within site-specific construction plans and documented within the land rights agreements. Trans Mountain has filed reports with the CER providing details on the landowner engagement program and results to date. In accordance with CER Condition 99, records of engagement and consultation with landowners and tenants will be filed with the CER at least 2 months prior to commencing construction and every 6 months thereafter until 5 years after commencing Project operations.

Trans Mountain’s landowner/tenant consultation strategy includes the activities described as follows.

1. Prior to Project approval - obtain landowner permission for survey, provide information on the Project and landowner rights, provide copies of land agreement documents to the landowners for their review and consideration, dialogue with each landowner to answer questions and address concerns raised by landowners, provide Project updates and disseminate any other information necessary to satisfy landowner requests and regulatory requirements. After addressing outstanding questions and issues,


01-13283-GG-0000-CHE-RPT-0027

Page F-11

obtain land agreements from landowners voluntarily. Land agreements have and will address specific landowner concerns regarding construction and reclamation activity.

2. After obtaining a Certificate of Public Convenience and Necessity from the CER, Trans Mountain will provide Section 34 notices indicating the detailed route for the pipeline and the specific lands affected by the Project, and complete any additional regulatory procedures required prior to commencement of construction, including providing reasonable notice through land agents of commencement date and activities. Trans Mountain land representatives will continue to maintain contact with landowners through construction to answer questions and address any issues that may arise. Following construction, maintain communication with landowners to discuss reclamation activities and timing. Upon completion of reclamation, Trans Mountain will transition the Project land program to operations.

Respecting this report, Trans Mountain notified landowners in September 2016 that CER Condition plans were being released for consultation and collected feedback. No feedback specific to this Facilities EPP was provided during the review process.
