CanEra Energy Corp. 90-Day Spill Summary Report 1 CE006032-03-03 10-05-006-03 W2 Battery


1. INTRODUCTION

A spill remediation program was conducted by Arletta Environmental Consulting Inc. (Arletta) at the

Willamar 10-05-006-03 W2 Multi-well Crude Oil Battery site (the “Site”) located within

10-05-006-03 W2M. At the time of the assessment, the Site was owned and operated by CanEra Energy

Corp. (CanEra).

The release occurred on November 19, 2013, due to the failure of a pressure recorder line within the

water disposal building. Approximately 5.0 cubic metres (m3) of produced water was released on site

into the surrounding environment affecting an approximate area of 220 square metres (m2).

The spill remediation program occurred on November 19, 2013. The objective of the program was to

assist with the remediation activities associated with the spill.

The scope of work completed at the Site included the following:

o conduct confirmatory sampling program to assess detailed salinity parameters;

O submit selected soil samples (based on field screening, visual observation and guideline

requirements) to accredited laboratories for analyses; and

O submit a comprehensive, technical report to the CanEra detailing the findings of the Spill

Remediation Program.

All work conducted by Arletta personnel was in accordance with Saskatchewan Occupational Health &

Safety legislation and safe work practices as defined in Arletta’s Health & Safety Manual. Any additional

safety standards and requirements presented by CanEra were also followed.

The purpose of this report is to summarize the remediation activities that occurred at the Site; to report,

analyze and present the confirmatory soil sampling data including comparison of results to the

applicable regulatory guideline (SPIGEC, 2009) and to make recommendations regarding what, if any,

further action is required.



2. SITE DESCRIPTION

The Site is located within 10-05-006-03 W2 approximately 22 kilometres (km) southwest of Carlyle,

Saskatchewan and approximately 7 km west of highway 9 (Figure 1). The lease is located on Freehold

land within a cultivated agriculture area.

According to the survey plan, the Site is 243.84 metres (m) x 76.2 m and is surrounded by cultivated

agriculture land (Survey Plan 1957; Appendix I). Access to the Site is from the 101/10-05-006-03W2

wellsite access road to the south of the battery.

At the time of the assessment, on site infrastructure included a third party production building, tank

farm, water injection tank, water pump building, header building, treater building, separator, flare stack,

flare line, groundwater collection tank, tile drainage system and risers. A graveled clay pad teardrop was

present around the production infrastructure. An aerial photograph of the Site and surrounding

landscape is presented in Figure 2.

2.1. PHYSIOGRAPHIC SETTING

2.1.1. Topography & Drainage

Topographic relief at the Site is gently undulating with nearly level slopes of 0 - 1 % (Saskatchewan Soil

Survey, 1993). Altitude is approximately 590 metres above sea level (masl) at the Site, to approximately

587 masl at a low ephemeral draw area approximately 630 m northeast of the Site (Abacus Datagraphics

Ltd., 2013). The nearest surface water body is an unnamed wetland approximately 840 m to the

southeast.

2.1.2. Soils

Soil within the area consist of a combination of Forget (Fg), Weyburn (Wr) and Brooking (Bk) soils

within the FgBk5 map unit. The soils are mainly orthic Fg and calcareous Wr, with solonetzic Bk on

gentle slopes, and saline or poorly drained soils in lower areas. Forget soils are fair agriculture soils of

capability class 3 and lower, limited by a moisture deficit imparted by a moderate water-holding capacity

and subhumid regional climate. The Dark Brown soil profile consists of loam to sandy loam deposits

over calcareous clay till (Saskatchewan Soil Survey, 1993).

The Site is located within a salt extent class 1 area with approximately 0 - 3% of the total area affected

by salinity. The agriculture productivity in this area has a reduction in yield of less than 2% of normal

yields on nonsaline areas. The area is located on the margin of sloughs and depressional areas. Soils



within the sloughs are leached and non-saline. Salts are generally not visible and electrical conductivity

(EC) of the surface soils average 2 - 4 deciSiemens (dS/m) (Saskatchewan Soil Survey, 1993).

2.1.3. Local Groundwater Use

There are eight groundwater extraction wells listed within 1 km of the Site (Mow-Tech Ltd., 2013;

Appendix II) used for industrial, domestic and unknown purposes. The nearest domestic water wells are

approximately 911 m southwest of the Site. The nearby domestic wells were completed to depths of 3.0

– 6.1 metres below ground surface (mbgs) suggesting domestic water levels are being utilized within

shallow surface depths. Water well locations were not field verified as part of this assessment.

2.2. HISTORICAL DOCUMENTED SPILLS

A search of the Government of Saskatchewan Environmental Protection Standards and Spill

Information Services Upstream Oil and Gas Sites Spill Notification Database (Government of

Saskatchewan, 2013; Appendix III), which contains current (to April, 2013) and historical spill reports

based on legal land description, indicated that there have been three spills filed for this facility location.

2.2.1. December 31, 1998 Produced Water Spill

A 60 m3 produced water spill was reported for December 31, 1998 with 60 m3 of fluids recovered. The

spill affected a 600 m2 area and was restricted to the onsite area. No information was available

concerning the area of the spill, cause of the release or the remediation activities.

2.2.2. September 13, 2005 Oil Spill

A 0.2 m3 oil spill was reported for September 13, 2005 with 0.2 m3 of fluids recovered. The total

affected area was 75 m2 along the access road with 10% of the spill area being off site in cultivated land.

The cause of the release was due to equipment failure. Impacted soil was reported as removed and

disposed at the Newalta Halbrite, Saskatchewan location.

2.2.3. June 18, 2008 Emulsion Spill

A 16 m3 emulsion spill (1.6 m3 of oil and 14.4 m3 of produced water) was reported for June 18, 2008

with 1.2 m3 of oil and 10.8 m3 of produced water recovered. The spill affected a 3,500 m2 area to the

northeast and east. All spill fluids were restricted to the onsite area. The cause of the release was due to a

treater equipment failure causing fluids to be released form the flare stack. Impacted soil was removed

and disposed at the Hazco landfill in Virden, Manitoba.



3. SPILL EVENT & REMEDIATION PROGRAM

The release occurred on November 19, 2013, due to the failure of a pressure recorder line within the

water disposal building. Approximately 5.0 m3 of produced water was released on site into the

surrounding environment affecting an approximate area of 220 m2. The spill path and impacted areas are

presented in Figure 3.

Upon discovery of the release, CanEra operators notified the Ministry of the Economy (ECON) and

arranged for a vacuum truck to remove pooled surface fluids. On November 19, 2013, under the

direction of CanEra operations personnel, a total of 6.5 m3 of impacted material (3.3 m3 of produced

water and 3.2 m3 of solids) was removed from the spill path and transported to the Plains

Environmental Willmar waste management facility located near Willmar, Saskatchewan located at

11-36-005-04 W2M. A summary of material disposed at the waste management facility is presented in

Appendix IV. Individual waste manifests are available upon request.

Photographs of the final spill remediation are included in Appendix V.

Confirmatory sampling of the spill impacted area and an additional background control sample was

conducted on December 2, 2013.



4. REMEDIATION REGULATORY GUIDELINES

The Saskatchewan Petroleum Industry/Government Environmental Committee Saskatchewan Upstream Petroleum Sites

Remediation Guidelines (SPIGEC No.4) is the principal document addressing soil and groundwater quality

at upstream oil and gas sites in Saskatchewan (SPIGEC, 2009). This document details electrical

conductivity (EC), sodium adsorption ratio (SAR), benzene, toluene, ethylbenzene and xylene (BTEX)

and total extractable hydrocarbon (TEH) C11-C60 fractions, ranges of values that require varying levels of

monitoring and treatment. Topsoil is considered to be the default criteria, unless the soil layer of

concern is at least 1.5 m below the A soil horizon and at least 1.5 m above the water table and contained

within an impermeable soil layer (or a synthetic liner), which qualifies the soil to be assessed under the

subsoil criteria.

Determination of regulatory guidelines is also based on existing land use or development restrictions.

Land use for the Site and surrounding area is agricultural. Agricultural lands are defined as having the

primary use of growing crops or tending livestock as well as human and transitory wildlife residence

(SPIGEC, 2009). Potential future land uses of the Site and surrounding area are likely to be similar to

current surrounding area land use; therefore, the guideline for agricultural land use has been applied for

soil parameters at the Site.



5. CONFIRMATORY SOIL SAMPLING

5.1. FIELD SAMPLING & METHODOLOGY

On December 2, 2013, a total of three soil samples were collected within the excavated spill area. One

background soil sample was collected off lease from within the cultivated field down gradient of the spill

pathway. All samples were collected as discrete samples from 0 - 15 centimetres below ground level

(bgl). Deeper soil samples were not attained due to frozen ground conditions. A diagram of the spill

path and soil sample locations is included in Figure 3.

All samples were collected in laboratory supplied plastic bags for analysis of inorganic parameters and

laboratory supplied glass jars for analysis of organic parameters.

All samples were transported in ice-packed coolers to Maxxam Analytics in Regina, Saskatchewan.

Standard chain of custody procedures were followed.

5.2. ANALYTICAL PROGRAM

On December 2, 2013, a total of three soil samples from the excavated spill path (131202 HA01, 131202

HA02 and 131202 HA03) and one background soil sample, 131202 C01 from the cultivated field north

of the battery were submitted for analysis of detailed salinity parameters including pH, electrical

conductivity (EC), sodium adsorption ratio (SAR), calcium (Ca), magnesium (Mg), sodium (Na),

potassium (K), chloride (Cl) and sulphate (SO4).

5.3. RESULTS & DISCUSSION

A summary of soil laboratory analytical results are presented in Table 1: Soil Salinity, Major Ions & pH.

Laboratory Certificates of Analysis, which include all analytical results, are presented in Appendix VI.

Salinity, Major Ions & pH

Electrical conductivity and SAR are the benchmark assessment parameters used to assess the degree and

magnitude of salinity contamination within a site. Contamination by produced water is generally

associated with elevated EC and SAR parameters caused by elevated sodium chloride concentrations. In

some locations, naturally occurring salts such as sodium sulphates can also lead to elevated salinity

values. Therefore, the composition and relative concentrations of major ions are often compared to

background soil sample concentrations and/or used as a secondary parameter to determine if the

elevated EC and SAR values are naturally occurring or anthropogenic.



Similarly, pH measurements identify the degree of acidity or alkalinity of soil conditions at a given site.

Contamination by produced water or introduced chemicals can result in pH levels outside of the

acceptable regulatory guidelines. In some locations naturally occurring acidic or alkaline soils can also

lead to elevated or decreased pH values. Therefore, the pH levels in soil samples are often compared to

background pH levels to determine if the overly acidic/alkaline pH measurements are naturally

occurring or anthropogenic.

All samples submitted for analysis of pH had reported pH values that satisfied the applicable guidelines

(SPIGEC, 2009).

The background soil sample had an EC value of 2.2 deciSiemens per metre (dS/m) (“Moderately

Tolerant Crops” to topsoil rating category) and a SAR value of 1.3 (“Unconditional Use” topsoil rating

category).

Confirmatory soil samples submitted for EC analysis had values ranging from 6.6 dS/m to 111.9 dS/m

(“Tolerant Crops” topsoil rating category – to outside the upper threshold of 8.0dS/m) and SAR values

ranging from 8.6 to 160 (“Conditional Use” topsoil rating category – to outside the upper threshold of

SAR 8). All confirmatory samples had EC and SAR values that did not meet the applicable guidelines

(SPIGEC, 2009).

Inorganic chemical concentrations including Ca, Mg, Na, K, Cl and SO4, were measured during the soil

sampling program. Elevated sodium and chloride concentrations above background levels were

reported.

Based upon the laboratory results the most heavily impacted soils have been removed from the surface

area on the active battery site at sample locations HA01 and HA03. Elevated sodium and chloride

concentrations remain at sample location HA02. Additional soil sampling is recommended at deeper

depth intervals and horizontally within the spill path to determine the extent of these salinity impacts.

Based upon the existing laboratory results additional removal of soils may be required.

5.4. QUALITY ASSURANCE/QUALITY CONTROL

For quality assurance purposes Maxamm regularly utilize calibration checks, surrogate matrix spikes,

blanks and laboratory duplicates during analysis. Results indicate that these quality assurance guidelines

were met, as outlined in the laboratory reports (Appendix VI).

The above described procedures and analytical controls meet the project requirements and industry

standards for laboratory holding times.



6. SUMMARY & RECOMMENDATIONS

The following is a summary of the findings from the Spill Remediation Program at the

10-05-006-03 W2 battery site:

o The release occurred on November 19, 2013, due to the failure of a pressure recorder line within

the water disposal building.

o Approximately 5.0 m3 of produced water was released on site into the surrounding environment

affecting an approximate area of 220 m2.

o On November 19, 2013, under the direction of CanEra operations personnel, a total of 6.5 m3

of impacted material (3.3 m3 of produced water and 3.2 m3 of solids) was removed from the spill

path and transported to the Plains Environmental Willmar waste management facility located

near Willmar, Saskatchewan located at 11-36-005-04 W2M.

o Confirmatory soil sampling of the excavated area and additional background control samples

was conducted on December 2, 2013 by Arletta personnel.

o All confirmatory and background soil samples submitted for pH satisfied the applicable

guidelines.

o Confirmatory soil samples submitted for EC analysis had values ranging from 6.6 dS/m to 111.9

dS/m (“Tolerant Crops” topsoil rating category – to outside the upper threshold of 8.0 dS/m)

and SAR values ranging from 8.6 to 160 (“Conditional Use” topsoil rating category – to outside

the upper threshold of SAR 8). All confirmatory samples had EC and SAR values that did not

meet the applicable guidelines (SPIGEC, 2009).

o Elevated sodium and chloride concentrations above background levels were reported at all soil

sample locations.

o Based upon the laboratory results the most heavily impacted soils have been removed from the

surface area on the active battery site at sample locations HA01 and HA03. Elevated sodium and

chloride concentrations remain at sample location HA02.

o Additional soil sampling is recommended at deeper depth intervals and horizontally within the

spill path to determine the extent of these salinity impacts. Based upon the existing laboratory

results additional removal of soils may be required.

NC (RPD): The RPD was not calculated. The level of analyte detected in the parent sample and its duplicate was not sufficiently significant to permit areliable calculation.

NC (Matrix Spike): The recovery in the matrix spike was not calculated. The relative difference between the concentration in the parent sample and thespiked amount was not sufficiently significant to permit a reliable recovery calculation.

Method Blank: A blank matrix containing all reagents used in the analytical procedure. Used to identify laboratory contamination.

Spiked Blank: A blank matrix sample to which a known amount of the analyte, usually from a second source, has been added. Used to evaluate methodaccuracy.

QC Standard: A sample of known concentration prepared by an external agency under stringent conditions. Used as an independent check of methodaccuracy.

Matrix Spike: A sample to which a known amount of the analyte of interest has been added. Used to evaluate sample matrix interference.

Duplicate: Paired analysis of a separate portion of the same sample. Used to evaluate the variance in the measurement.
