Screening and assessment of potential environmental impacts: ADB requires the consideration of environmental issues in all aspects of the Bank’s operations, and the requirements for environmental assessment are described in ADB’s Safeguard Policy Statement (SPS), 2009. This states that ADB needs environmental assessment of all project loans, program loans, sector loans, sector development program loans, and loans involving financial intermediaries, and private sector loans. Accordingly, this Initial Environmental Examination (IEE) has been conducted to assess the environmental impacts of the infrastructure components proposed under Upgradation of Major Roads in Agartala City Urban Development Project. Initial Environmental Examination (IEE): This IEE aims to (i) provide critical facts, significant finding, and recommended actions; (ii) present the national and local legal and institutional framework within which the environmental assessment has been carried out; (iii) provide information on existing geographic, ecological, social and temporal context including associated facilities within the subproject’s area of influence; (iv) assess the subproject’s likely positive and negative direct and indirect impacts to physical, biological, socioeconomic, and physical cultural resources in the subproject’s area of influence; (v) identify mitigation measures and any residual negative impacts that cannot be mitigated; (vi) describe the process undertaken during project design to engage stakeholders and the planned information disclosure measures and the process for carrying out consultation with affected people and facilitating their participation during project implementation; (vii) describe the subproject’s grievance redress mechanism for resolving complaints about environmental performance; (viii) present the set of mitigation measures to be undertaken to avoid, reduce, mitigate, or compensate for adverse environmental impacts; (ix) describe the monitoring measures and reporting procedures to ensure early detection of conditions that necessitate particular mitigation measures; and (x) identify who is responsible for carrying out the mitigation and monitoring measures. The IEE is prepared after detailed design and no major design changes are expected in the subproject during implementation. However, the IEE will be updated/ revised if there are any changes in site/ locations and design of components during preconstruction phase. It will also be updated/ revised based on review of draft IEE and conditions of consents/ approval from other departments. The updated/ revised IEE will be submitted to ADB for review and disclosure. No works will be conducted until ADB has cleared the updated/revised IEE. The revised IEE shall supersede the earlier version of IEE and shall be contractually applicable to the contractor after approval from Agartala Smart City Limited (ASCL) and ADB.

Categorization. Potential negative impacts were identified in relation to pre-construction, construction and operation of the improved infrastructure, but no permanent environmental impacts were identified as being due to either the subproject design or location. Accordingly, Agartala upgradation of roads subproject is classified under environmental Category B as per the SPS as no significant impacts are envisaged. Further mitigation measures have been developed to reduce all negative impacts to acceptable levels. These were discussed with specialists responsible for the engineering aspects, and as a result some measures have already been included in the designs for the infrastructure. Description of the Environment: Information on baseline environment was collected from primary survey for air quality, water quality, noise quality and, soil quality and ecological components conducted in December 2018- January 2019 and secondary sources of data for the macro environmental parameters like climate, physiography (geology and geomorphology), biological and socioeconomic environment of the project influence area. Agartala is the Capital of Tripura and is an urban settlement and there is no natural habitat at the sites. The project does not involve any

vi

type of land acquisition or land use change as it is an up gradation of the existing roads within the existing RoW (Right of way). There are no mangroves, or estuaries in or near the project location. There are no forest areas within Agartala. Traffic management will be necessary during up gradation of the busy roads such as HGB Road, Mantribari Road, Thakurpalli road Ronaldsay Road, GB Road, Jail Ashram Road etc.,

Potential Environmental Impacts and Mitigation Measures. In this IEE, negative impacts were identified in relation to location, design, construction and operation of the improved infrastructure. Environmental impacts as being due to the project design or location were not significant as various measures are already included in site planning and detailed design. There are no environmentally or archeologically sensitive areas within Agartala town. The town is mostly surrounded by agricultural areas, and there are no sensitive areas like forests. Potential impacts during construction are expected and will be considered but are temporary in nature and are common impacts of construction in urban areas, and there are well developed methods to mitigate the same. All other construction activities will be confined to the selected sites and the interference with the general public and community around is minimal. In these works, the temporary negative impacts arise mainly from construction dust and noise, hauling of construction material, waste and equipment on local roads (traffic, dust, safety etc.), mining of construction material, occupational health and safety (OHS) aspects. Road construction works will be conducted along already existing public roads in an urban area congested with people, activities and traffic. Therefore, these works may have adverse, but temporary impacts arising mainly from the disturbance of residents, businesses and traffic due to construction work; safety risk to workers, public; access impediment to houses and business, disposal of large quantities of construction waste etc. These are all general impacts of construction in urban areas and there are well developed methods of mitigation that are suggested in the EMP. Environmental Management Plan. Environmental Management Plan (EMP) includes the implementation procedure of the guidelines and mitigation measures recommended to avoid, minimize and mitigate foreseen environmental impacts of the project. The implementation of environmental management plan needs suitable organization set up and the success of any environmental management plan depends on the efficiency of the group responsible for implementation of the programme. It is proposed to carryout regular environmental monitoring to provide information to the management for periodic review and alteration of the environmental management plan is necessary to ensure that environmental protection is optimized at all stages of the project. PIU is responsible for implementing all environmental monitoring and management works during implementation of Roads upgradation project Revitalization project to achieve certain level of quality in the project and ensure that all statutory requirements are met during the project implementation. The engineering staff of PIU, supervision consultancy and the contractor who would be responsible for the implementation of the EMP, need to be trained on environmental issues of Road upgradation project. EMP implementation budget for the proposed project is Rs. 1,78,55,634. A copy of the approved EMP will always be kept on site during the construction period. The EMP has been made binding on contractor operating on the site and included in the bid and contract documents. Non-compliance with, or any deviation from, the conditions set out in this document constitutes a failure in compliance. Contractor will establish the baseline environmental conditions prior to commencement of civil works.

During Implementation, contractor team shall include an Environmental, Health & Safety (EHS) Officer and a Social Safeguard Officer

Consultation Disclosure and Grievance Redress: The stakeholders were involved in developing the IEE through discussions on-site and public consultation, after which views expressed were incorporated into the IEE and in the planning and development of the project. The IEE will be made available at public locations in the city and will be disclosed to a wider audience via the ADB and ASCL websites. The consultation process will be continued and expanded during project implementation to ensure that stakeholders are fully engaged in the project and can participate in its development and implementation. The citizens of the Agartala City will be the major beneficiaries of this subproject. During the construction stage the project will provide employment opportunity and enhance the enterprise development of locals. There will also be skill development due to the project implementation. A project specific grievance redress mechanism is described within the IEE to ensure any public grievances are addressed quickly.

Monitoring and Reporting: The ASCL and Project consultants will be responsible for monitoring. The consultant will submit monthly monitoring reports to ASCL and ASCL will send semi-annual monitoring reports to ADB. ADB will post the environmental monitoring reports on its website. Conclusions: The citizens of the Agartala will be the major beneficiaries. The subproject is primarily designed to improve environmental quality and living conditions of Agartala town through provision of improved roads. The benefits arising from this subproject include: (a) improve drainage infrastructure to reduce urban floods; (b) improve public health by providing 48.2 km of new or rehabilitated stormwater drains; (c) visual improvement elements including dedicated footpaths with street furniture, tree belt and landscaping

The proposed subproject is unlikely to cause significant adverse impacts on either the environment or the human health and safety. The potential impacts that are associated with design, construction and operation can be mitigated to standard levels without difficulty through proper engineering design and the incorporation or application of recommended mitigation measures and procedures.

7. ADB requires the consideration of environmental issues in all aspects of the bank’s operations, and the requirements for environmental assessment are described in its Safeguard Policy Statement (SPS), 2009. The proposed projects are categorized as A, B, C or FI to determine the level of environmental assessment required.6 The proposed project, “Upgradation of Major Roads’ will not have any significant environmental impacts during pre-construction, construction and operation phase as the proposed project involves laying of roads and drainage. Therefore, the subproject is classified as Environmental Category B as per the SPS, 2009 as no significant impacts are envisaged. ADB’s Rapid Environmental Assessment (REA) Checklist was used to assess the impacts (Appendix 1) and accordingly, this initial environmental examination (IEE) report has been prepared. Further mitigation measures have been developed to reduce all potential impacts to acceptable levels. These were discussed with specialists responsible for the engineering aspects, and as a result some measures have already been included in the designs for the proposed project.

5 The subprojects include (i) Storm water drains, (ii) Sewerage, (iii) Urban Roads, (iv) Water Supply, (v) Open spaces and water bodies, and (vi) Housing for Economically weaker sections

6 Per ADB SPS, the environmental categorization and level of environmental assessment required for each category are as follows: (i) Category A: A proposed project is classified as category A if it is likely to have significant adverse environmental impacts that are irreversible, diverse, or unprecedented. These impacts may affect an area larger than the sites or facilities subject to physical works. An environmental impact assessment is required. (ii) Category B: A proposed project is classified as category B if its potential adverse environmental impacts are less adverse than those of category A projects. These impacts are site-specific, few if any of them are irreversible and, in most cases, mitigation measures can be designed more readily than for category A projects. An initial environmental examination is required. (iii) Category C: A proposed project is classified as category C if it is likely to have minimal or no adverse environmental impacts. No environmental assessment is required although environmental implications need to be reviewed. (iv) Category FI: A proposed project is classified as category FI if it involves investment of ADB funds to or through a financial intermediary.

8. Scope of the IEE. The IEE is prepared based on the detailed designs considered in detailed project report (DPR) and based on secondary sources of information, field reconnaissance surveys, primary field monitoring (environmental) survey and stakeholder consultation. There are no major design changes expected in the subproject during implementation. However, the IEE will be updated/ revised if there are any changes in site/ locations and design of components during construction phase. The updated/ revised IEE will be submitted to ADB for review and disclosure. No works will be conducted until ADB clears the updated/revised IEE.

9. This IEE will be reviewed during detailed design stage and project implementation and updated if there is any change in scope of works, change in location of component and change in cost due to addition or subtraction of components which can change the environmental impacts, and revised IEE shall supersede the earlier version of IEE and shall be contractually applicable to the contractor after approval from ASCL and ADB. 10. The implementation of the subprojects will be governed by Government of India and State of Tripura and other applicable environmental acts, rules, regulations, and standards. Environmental safeguards will be followed in accordance with the ADB SPS 2009. During the design, construction, and operation of the project the borrower/client will apply pollution prevention and control technologies and practices consistent with international good practice, as reflected in internationally recognized standards.

II. DESCRIPTION OF PROJECT COMPONENTS

A. Subproject Location

12. Agartala is spread over an area of 76.5 square kilometers (km2), located at 23°50’N Latitude and 91°17’’E Longitude. The city lies on the bank of the Haora River although the city also extends to the low-lying hills on its northern parts. It is located 2 km away from the Bangladesh Border. It is the most important commercial hub of the state and important trade route to the north-eastern states. The border connectivity with neighboring country Bangladesh makes Agartala an important trading hub for Import and Export. The project is spread across the entire Agartala city.

B. Present Status of the Roads

13. Existing condition: The traffic in Agartala City limits is moderate in nature and congestion is mainly due to homogenous traffic of motorized and non-motorized category. Road inventory surveys were carried out for the road stretches identified for up-gradation and improvement proposals to assess the existing conditions. The existing scenario of major roads are described below, and the conditions are shown in Figure 1.

(i) On street parking on busy roads is a major point of concern. It reduces the effective carriageway width, encourages hawkers to occupied pedestrian walkways leading to traffic congestion. Such occurrence can be visualized in Hari Gnaga Basak Road, Orient Chowmuhani, Battala Chowmuhani, Shakuntala Road, BT Road, Ronaldsay Road.

(ii) The Drain cum Footpath along the arterial roads are not in use by the pedestrians as they are encroached by the hawkers, adjacent vendors and commercial outlets. Such as in Hariganga Basak Road, Thakurpalli Road, etc.,

(iii) In some roads, there are no dedicated footpaths along the sub-arterial roads. (iv) Poor condition of pavement. (v) Some road junctions are encroached by Autos/Rickshaws parking and auto stands (vi) In some roads, the drainage channels are partially covered which is hazardous for

the pedestrian use. (vii) Landscaping and visual aspects along the road are not satisfactory. (viii) Utilities like electric poles and wiring are exposed and visually clattered. (ix) There is no CCTV Surveillance. (x) There is no dedicated bus bays and bus stop/stand locations. (xi) There is no proper traffic maneuver movement, proper lane markings and traffic

signage’s at junctions or at major Bus terminals.

14. Existing condition analysis: Road inventory surveys were carried out for the road stretches identified for Up-gradation and Improvement proposals to assess the existing conditions. The conclusion drawn based on the analysis of the existing system are as follows:

(i) For the existing traffic, the roads have reached the saturation level and are operating at Level of Service “C”. This situation can be improved by restrictions of on street parking and providing parking proposals; especially for HGB Road and Akhaura Roads wherein the commercial activities are more predominant.

(ii) Lane configurations, equally divided carriageway with median proposals will guide the traffic movements in dedicated and respective directions.

(iii) There are no footpaths, cycle track, tree lane, utility ducts/ dedicated corridor on either side of the road. Facilities shall be proposed for the same.

(iv) Junctions are not as per standards, needs to be improved as per the standards for smooth traffic flow at junctions.

(v) There are no pedestrian crossing facilities at junctions. Provisions to be made for crossings at the Major Junctions and at suitable locations.

(vi) There is no road furniture present in the project stretch. Same shall be included in the project proposal.

(vii) Bus shelters and Bus bays to be proposed at suitable locations with aesthetical and structural improvements.

(viii) On-street parking, Auto stand, Public/ E-Toilets, Street lighting and Sign boards, etc., shall be proposed and upgraded with smart features.

(ix) Smart street components such as Smart poles, CCTV, VMS, and other ICT components shall be included in the development of Project stretch.

(x) The RoW of the roads in Agartala are less, trees along the shoulder of roads, gradient of road profile, retaining the existing drains and the no of utilities required per road are of less size and numbers, Pipe Conduit system shall be proposed for Overhead to Underground of Electrical, Telephone and OFC lines for these stretches of proposed roads.

(xi) Existing storm water drains are found to be choked up with solid waste and silt, so desilting and removing of solid waste and laying continuous slab will solve this issue and provide good walkways to the pedestrians.

C. Proposed Subproject Components

15. The scope of works involves up gradation of existing infrastructure involving widening of roads, providing continuous obstacle free footpaths, pedestrian crossings etc. within the existing ROW as enumerated in Table 1.

20. Proposals for Utility Corridor & Overhead to Underground Conversion of Transmission Lines: As suggested under smart city features in the Smart City Guidelines, cities need to focus on energy efficiency and promote underground electric wiring to ensure continuous electricity supply. City of Agartala has a network of 11kv, 33 kv and LT lines located along the proposed selected roads for upgradation. Considering the human safety, aesthetic view of the city, traffic needs and uninterrupted supply requirements, ASCL intends to make an underground utility corridor for conversion of overhead line network to underground cable system. The proposal of underground utility corridor consists of providing of:

(i) Utility Trench with Cable Tray system (ii) Utility Conduit (Ducting- Pipe and Manhole) system

21. The City has a mix of transmission network for its HT and LT systems. The HT networks in the city are mostly laid overhead through transmission lines. However, in some areas the HT networks are laid in pipes directly buried underground and are aerially visible only at the termination points at various Distribution Transformer Centers. Most of the 415V LT systems are laid overhead through transmission lines. These HT and LT lines are laid on the same or different cement (PSC) or metal (RSJ) poles. These transmission lines are laid along either side of the roads with the poles mounted at the edge of the road. 22. The street lights on these roads are also mounted on same electric poles which are carrying the transmission lines. Since these transmission lines would be converted to Underground cables, these poles would be removed. The upgradation work includes scope of provision of new Octagonal/ tubular GI Poles including the bracket, LED fixtures, feeder pillar and cables.

D. Other features:

23. Bridges and culverts: All the hydraulic data for bridges has been collected from the field and analyzed to determine the adequacy of waterways. Based on the assessment no bridges and culverts are considered for development.

21

24. Railway Crossing: There is no railway crossing across the proposed subproject. The proposed improvement will be limited along the existing ROW.

25. Design standards, Cross Sections improvements: The design standards adopted for the study have been evolved based on a study of the existing standards and practices in the country keeping in view the standards recommended by IRC and MoUD. The standards so evolved are presented below.

E. Design Concept

26. Analysis of Classified Traffic volume count surveys done during traffic assessment studies for Agartala City shows that the carriageway widths are enough on some road sections and require upgradation to additional lanes. As the required Right of Way cannot be made available in the core ABD area, it is decided to propose the Upgrade/improvement proposals within the available ROW and conversion of above ground utilities to underground. This process will avoid Land acquisition process and henceforth to design a retrofit model for implementation of smart road concept in Agartala City Urban Development Project. Various levels of discussions based on the available data and site conditions has led to development of four design concepts, these design concepts are applied to various sections of the road according to the existing site conditions and available utilities. Strip plan of individual roads are attached in Appendix 17. 27. Design Concept-I: This concept is applicable where there are brick storm drains at both sides of the roads and the same to be remodeled. Based on this, the concept two (2) vent RCC structure is proposed. Out of which one vent (Towards the carriageway) shall carry Storm Water and other one (Towards the property line) shall carry Electrical and OFC cables. The vent for ormElectrical & OFC system will be provided below the footpath wherein pedestrian loads has been considered and SWD vent shall be provided below the carriageway (At the edge) and the same will be designed for vehicular movement. This concept is proposed for road sections listed below:

(i) Hariganga Basak Road: The entire road length has SWD of Brick material, thus Design Concept – I is applicable to entire road length. Seven typical sections are generated as per site requirements for the Road length of 3.48 Km.

(ii) Mantribari Road: The entire road length is proposed to be developed as per this concept for the Road length of 0.258 Km.

(iii) Thankurpalli Road: The Road section from Bidurkarta to Ganaraj Chowumhai is proposed to be upgraded with this concept. The section length is 0.74 Km.

(iv) VIP Road: From Circuit House Chowmuhani to St. Francis Church. The length of this section is 3.00 km.

(v) Shankuntala Road: Section from Surya Chowmuhani To Orient Chowmuhani of length 0.2 Km.

(vi) ITI Road: Section from GB Chkkar to ICCC location of length 0.39 Km. (vii) GB Road: Playground near GB hospital to Ganaraj Chowmuhani of length 1.0 Km. (viii) Barjala Road: Barjala road Airport Trijunction to Durga Chowmuhani Bridge of

length 3.49 Km. (ix) Ronaldsay Road: Entire Ronaldsay road of length 1.1 Km. (x) Jail Ashram Road: Entire Jail Ashram road of length 1.547 Km. (xi) Lankamura Road: Entire road length of 0.21 Km.

28. Design Concept-II: This concept is proposed at the locations where existing RCC Storm Water Drain is on one side and Brick Storm Water Drain is on other side of the road section. Accordingly, the proposal Side-1 (RCC Storm Water Drain Side): Existing RCC Storm water drain is retained. However, OFC & Electrical Cables are proposed to be taken underground through utility conduit system below the carriageway by the side of the drains. This conduit system is will be covered with heavy duty Paver Blocks. Improvement of existing Storm Water Drain surface for pedestrian movement with aesthetic elements to be taken up. And Side-2 (Brick Storm Water Drain Side): Existing Brick Drain is remodeled and a two vent RCC structure is proposed. Out of which one vent shall carry Storm Water Drain and other one shall carry Electrical and OFC cables. The vent for Electrical & OFC system will be provided towards property line and designed for

38

pedestrian movement as well. SWD vent is designed for vehicular movement and will be below the carriageway. This concept is proposed for road sections listed below:

(i) Akhaura Road: Road section from Orient chowmuhani to Jackson Gate chowmuhani is proposed to be upgraded with this concept for the Road length of 0.19 km.

(ii) Thankurpalli Road: Road section from Ker Chowmuhani to Bidurkarta Chowmuhani is proposed to be upgraded with this concept. The section length is 0.98 km.

(iii) GB Road: Abhoynagar trijunction to playground of length 0.648 km. and Abhoynagar bridge to Ramthakur Club Chowmuhani of length 1.2 km.

(iv) Jail Road: Entire jail road length of 0.5 km.

29. Design Concept-III: This concept is proposed where the existing RCC Storm Water Drains are present on both sides. In this concept, the existing SWD structure is retained and a Utility Conduit System below the carriageway with heavy duty Paver blocks at the top. The utility conduit alley shall be at the edge of the carriageway. However, in view of maintenance and overlay of road bituminous surface, the main carriageway (Portion without covered with paver blocks) with cement concrete pavement is proposed. This concept is proposed for road sections listed below:

(i) VIP Road: Road section from Radhanagar Motorstand to Circuit House Chowmuhani. This section has existing footpath and trees on RHS and trees with large girth on LHS. The footpath on RHS is retained. However, on LHS, the footpath is proposed between Road edge line and Compound wall of Assam rifles. The length of section is 0.62 Km.

(ii) Thakurpalli Road: Road section from Ganaraj Chowmuhani to Purbasha is to be upgraded with this concept for the section length of 0.38 Km.

(iii) Shankuntala Road: Section from Orient Chowmuhani To Rabindra Bhawan length of 0.3 km.

30. Design Concept - IV: This concept is proposed at the locations where existing RCC Storm Water Drain is on one side and Brick Storm Water Drain is on other side of the road section. Accordingly, the proposal is, Side-1 (RCC Storm Water Drain Side): Existing RCC Storm water drain is retained. However, OFC & Electrical Cables are proposed to be taken underground through utility conduit system below the carriageway by the side of the drains. This conduit system is will be covered with heavy duty Paver Blocks. Improvement of existing Storm Water Drain surface for pedestrian movement with aesthetic elements to be taken up Side-2 (Brick Storm Water Drain Side): Existing Brick Drain is remodeled and a two vent RCC structure is proposed. vent shall carry Storm Water Drain and other one shall carry Electrical and OFC cables. The vent for Electrical & OFC system will be provided towards property line and SWD towards carriageway. Combined width of this structure is proposed for pedestrian movement only. This two-vent structure will be above the finished road level as per IRC standards for pedestrian safety concern. This concept is applicable for Akhaura Road: Road section from IGM Chowmuhani to Orient Chowmuhani is proposed to be upgraded with this concept for the Road length of 0.54 km. The typical section drawing for each concept in shown in Figure 17-20 below and the details of design component like pathways, storm water drains and electrical trenches for each road is provided in Table 5.

F. Construction Methodology

31. The upgradation / Improvements proposals of the Major roads of 23.562 km (15 nos) are based on the Design Concepts and their applicability on the road sections is already given in Section C of this chapter. Construction methodology of each concept is described below: 32. Site clearance and Earthwork: Site clearance of the existing road sections include:

(i) Removal of rubbish, ground clearance (ii) Cutting of trees, including cutting of trunks, branches and removal of stumps &

roots, refilling the disturbed area. (iii) Dismantling of Chambers, Kerb stones, Removal of RCC slab covers and

dismantling of existing brick work drains. (iv) Dismantling of existing Flexible pavement, existing manholes of various services /

underground utilities along the proposed road sections (Water pipeline, OFC and Gas Pipelines).

(v) Carriageway of materials and haulage.

33. Utility Conduit / Utility Cable Tray System: Design concepts developed based on the proposed utility system and existing Storm water drain structures shall be implemented broadly by three types of construction methodologies/strategies. They are:

(i) Construction methodology for implementation of new Two vent RCC structure on both sides of the road section is: (a) This concept has new RCC structure with SWD + Utility cable tray

combination with an average width of 2.5m and depth of 2.0m. For this existing brick water drains and existing Pavement surface adjacent to SWD to be dismantled to make clear working area for the RCC structure.

(b) Stretches between crossroads can be taken up for new construction at an alternate interval of next crossroad connectivity.

(c) This methodology to be adopted at staggered manner along the road section.

49

(d) Existing connections of underground utilities with the adjacent household connections need to be re-connected or re-laid before the fabrication of the top slabs on RCC structure are laid.

(e) With the top slabs ready for vehicular movement over SWD structure and pedestrian movement over Cable tray structure, completion of cross drain structure works and across the cable tray connections (electrical / OFC lines); the subgrade levels of the disturbed road section to be re-constructed.

(f) Paver tiles + cement mortar over RCC slab of utility cable tray system with tactile paving to be done.

(g) Scarification of existing road surface to attain the finished road levels w.r. to the overlay thickness proposed.

(h) Laying the overlay pavement compositions as per provisions. Bituminous concrete, Dense Bituminous concrete, Bituminous Macadam and Profile correction also with Bituminous Macadam layer.

(i) Road furniture such as Traffic signages, road marking and furniture related to traffic safety and traffic calming measures.

(j) Implementation of landscape related works.

(ii) Construction methodology for implementation of new Two vent RCC structure on one side and utility conduit system with paver block pavement as finished surface on other side is: (a) For the side with existing brick drain and its reconstruction into Two vent

RCC structure construction methodology given in strategy-A to be followed excluding point - III.

(b) For the side with existing RCC structure and the proposed utility conduit system to accommodate the Electrical lines, OFC lines and Gas pipelines shall be rest on suitable sand and fine aggregates (10mm to 20mm) layer as per technical specifications and standards.

(c) Initially the manual excavation along existing road portion of width 2.0m from the face of drain and up to a depth of 2.0 m is considered. The bed shall be leveled after complete excavation.

(d) The excavated area shall be kept dry during the backfilling with suitable dewatering method, if required.

(e) Backfilling of good earth layers upto 600mm as per standard compaction methodology and MoRTH Specifications.

50

(f) Pipe conduits of 11kv lines, LT lines and OFC cable lines are laid in a sand layer embedded with safe offset distance above and below the Gravel layer respectively. The overall depth of this layer including cushion and Pipe laying combination is 1220mm.

(g) Preparation of Base layers for M50 Grade 100mm CC Blocks: As per the recommendations of base layers given in IRC: SP: 63-2004, layer systems are proposed and they are: • Gravel layer of 250mm over back filled earth layer • Water bound macadam layer of 250mm • Sand layer of 30mm as bed layer for paver blocks • 100mm paver blocks.

(h) Edge restraint blocks or edge strip is proposed: as per Clause 4.6 of IRC:SP:63 -2004, to avoid the displacement of concrete blocks due to braking and maneuvering of vehicular movement on the edges. In-situ edge block of M-30 grade concrete section is proposed between paver blocks and existing road base layers of 300 x 450 mm.

(iii) Construction methodology for implementation of Utility conduit system with paver block pavement as finished surface on both sides: (a) To retain the existing RCC structure and the proposed utility conduit system

to accommodate the Electrical lines, OFC lines and Gas pipelines shall be rest on suitable sand and fine aggregates (10mm to 20mm) layer as per technical specifications and standards.

(b) Initially the manual excavation along existing road portion of width 2.0m from the face of drain and up to a depth of 2.0 m is considered. The bed shall be leveled after complete excavation.

(c) The excavated area shall be kept dry during the backfilling with suitable dewatering method, if required.

(d) Backfilling of good earth layers upto 600mm as per standard compaction methodology and MoRTH Specifications.

(e) Pipe conduits of 11kv lines, LT lines and OFC cable lines are laid in a sand layer embedded with safe offset distance above and below the Gravel layer respectively. The overall depth of this layer including cushion and Pipe laying combination is 1220mm.

(f) Preparation of Base layers for M50 Grade 100mm CC Blocks: As per the recommendations of base layers given in IRC: SP: 63-2004, layer systems are proposed and they are: • Gravel layer of 250mm over back filled earth layer

51

• Water bound macadam layer of 250mm • Sand layer of 30mm as bed layer for paver blocks • 100mm paver blocks.

(g) Edge restraint blocks or edge strip is proposed: as per Clause 4.6 of

IRC:SP:63 -2004, to avoid the displacement of concrete blocks due to braking and maneuvering of vehicular movement on the edges. In-situ edge block of M-30 grade concrete section is proposed between paver blocks and existing road base layers of 300 x 450 mm.

34. Construction Material: Material required for construction will be explored from the project area. Existing sites which are operated with relevant licenses and approvals will be used especially for extraction of metal and sand. Offshore sand could also be used for construction subjected to confirmation of quality. If new material extraction sites will be opened for this project, necessary licenses and approvals will be obtained from relevant agencies. Based on the engineering estimates prepared for each road, approximate quantities of material required for the district is given in table below; The natural raw materials like sand, gravel and soil shall be procured/ sourced from the authorized mines listed by Tripura Government as specified in the website http://trpenvis.nic.in/test/natural_resources.html. Of these raw materials, gravel is brought/ imported from mines in Assam state mainly from Harangajao mines which is at a distance of around 334 Km from Agartala, Bituminous macadam is brought is from Haldia in West Bengal state and partially from Assam state.

III. ANALYSIS OF ALTERNATIVES

38. No Project Alternative: The ‘No project scenario’ is analyzed with respect to the development of Agartala City as a requirement of reliable quality infrastructure for sustained growth of economy and consequent well-being of its citizens. Providing better connectivity within the city will ensure that, goods and people from areas accessed by the road can commute quicker and save time. Increase in trade and commerce activity is expected. The savings in the vehicle operating costs makes the subproject viable. 39. In terms of environmental quality, not improving the roads will contribute to the further deterioration of the road surface, and traffic congestion on the roads. Poor road surface will result to increase in fuel consumption and combustion gas emissions and increase in noise and dust levels which will result to poorer air quality particularly immediately along the project road. Limiting the road improving to the available ROW also minimized the need for vegetation clearing and tree cutting. 40. If the subproject is not implemented, there is every likelihood that the existing bad pavement of the corridor deteriorates further. In the absence of the proposed subproject, the districts will also find it extremely difficult to generate revenue. Increased air pollution, due to bad road condition, slow moving traffic and congestion, will increase as the time goes by. Noise levels will rise due to deterioration of the pavement as well as increased honking. Without the improvement of subproject, the traffic would continue to pose a safety risk for the road users.

41. Therefore, ‘project with alternatives’ scenario, with its minor adverse impacts are more acceptable than ‘No project scenario’ which would mean an aggravation of the existing problems. Potential benefits of the proposed road improvements are substantial and far reaching both in terms of the geographical spread and time. Hence the implementation of the subproject will be a definite advantage to Agartala to achieve all-round development of its economy and progress for its people.

42. With Project Alternative: The subproject alternatives in terms of location (alignment) option are very limited as the project objective is to improve the existing roads. With the project, 23.562 km of urban road will be upgraded and maintained to all weather standards. On the other

54

hand, once the accessibility is increased, the travel time to centers such as hospitals, schools, markets and other infrastructure facilities available in town centers will be reduced. Therefore, this is a timely required project to facilitate the socioeconomic development of the densely populated city of Agartala and ultimately for the development of the country.

43. Identification of subproject roads for development: The road selection under Agartala Smart City ADB project is done keeping in view the Strategic importance, Connectivity to the adjoining important locations such as Major areas including important National Highways and State Highways, Market Places, Important Structures and Locations. 44. The selection of roads which are done on the basis of connection to major trade centers, markets and commercial areas are:

(i) Hari Ganga Basak (HGB) Road (ii) Mantribari Road (iii) Thakurpalli Road (iv) Akhura road (v) ITI Road (vi) Road Surrounding IT hub (vii) GB Road (viii) Shakuntala Road (ix) BT Road (x) Jail Road

45. The selection of roads which are done on the basis of connection to major National and State Highways and Important places are:

(i) VIP Road (ii) Barjala Road (iii) Jail Ashram Road (iv) Ronaldsay Road

46. The selection of roads which are done on the basis of connection to Important Structures, places and locations with strategic importance are:

(i) Lankamura Road

47. Few sections of the road like, VIP road stretch from Lichubagan to Agartala Airport has been dropped, as the road construction and widening required felling of trees and land acquisition.

IV. POLICY, LEGAL AND ADMINISTRATIVE FRAMEWORK

A. ADB Policy

48. ADB SPS requires that during the design, construction and operation of the project necessary compliance to all applicable laws and international conventions / treaties along with pollution prevention and control technologies and practices consistent with international good practice, are ensured.

55

49. Screening and Categorization with that of ADB SPS 2009: ADB uses a classification system to reflect the significance of a project’s potential environmental impacts. A project’s category is determined by the category of its most environmentally sensitive component, including direct, indirect, cumulative, and induced impacts in the project’s area of influence. Each proposed project is scrutinized as to its type, location, scale, and sensitivity and the magnitude of its potential environmental impacts. Projects are assigned to one of the following four categories:

(i) Category A. A proposed project is classified as category A if it is likely to have significant adverse environmental impacts that are irreversible, diverse, or unprecedented. These impacts may affect an area larger than the sites or facilities subject to physical works. An environmental impact assessment is required.

(ii) Category B. A proposed project is classified as category B if its potential adverse environmental impacts are less adverse than those of category A projects. These impacts are site-specific, few if any of them are irreversible, and in most cases mitigation measures can be designed more readily than for Category A projects. An initial environmental examination is required.

(iii) Category C. A proposed project is classified as category C if it is likely to have minimal or no adverse environmental impacts. No environmental assessment is required although environmental implications need to be reviewed.

(iv) Category FI. A proposed project is classified as category FI if it involves investment of ADB funds to or through a FI.

50. The environmental impacts of upgradation of major roads in Agartala City have been identified and assessed as part of the planning and design process. An environmental assessment using ADB’s Rapid Environmental Assessment Checklist for Urban development (Appendix 1) was conducted, and results of the assessment show that the subproject is unlikely to cause significant adverse impacts. Thus, this IEE has been prepared in accordance with ADB SPS’s requirements for environment category B projects. 51. Environment Management Plan: An EMP which addresses the potential impacts and risks identified by the environmental assessment shall be prepared. The level of detail and complexity of the EMP and the priority of the identified measures and actions will be commensurate with the Project’s impact and risks. 52. Environmental Audit of Existing Facilities. ADB SPS requires an environmental audit, if a subproject involves facilities and/or business activities that already exist or are under construction, including an on-site assessment to identify past or present concerns related to impacts on the environment. The objective of this compliance audit is to determine whether actions were in accordance with ADB’s safeguard principles and requirements for borrowers/clients, and to identify and plan appropriate measures to address outstanding compliance issues.

53. The excess C&D waste for construction will be processed at C&D waste management site at DC Nagar Lunga, Therefore the existing C&D processing site is an associated facility as per the ADB Safeguard Policy Statement 2009. Compliance with the environmental safeguards will ensure the subproject sustainability. The Environmental Audit Report of Existing C&D waste Management site in Agartala is attached as Appendix 6. 54. Public Disclosure: The IEE will be put in an accessible place (e.g., local government offices, libraries, community centers, etc.), and a summary translated into local language for the project affected people and other stakeholders. The following safeguard documents will be put up

56

in ADB’s website so that the affected people, other stakeholders, and the public can provide meaningful inputs into the project design and implementation:

(i) For environmental category A projects, a draft EIA report at least 120 days before Board consideration;

(ii) Final or updated IEE upon receipt; and (iii) Environmental monitoring reports submitted by the Project Implementation Unit

(PIU) during project implementation upon receipt.

55. Consultation and Participation. ADB SPS require borrower to conduct meaningful consultation7 with affected people and other concerned stakeholders, including civil society, and facilitate their informed participation. The consultation process and its results are to be documented and reflected in the environmental assessment report. 56. Grievance Redress Mechanism. ADB SPS require borrowers to establish a mechanism to receive and facilitate resolution of affected people’s concerns, complaints, and grievances about the subproject’s performance. The grievance mechanism shall be scaled to the risks and adverse impacts of the subproject. 57. Monitoring and Reporting. Borrower shall monitor, measure and document the implementation progress of the EMP. If necessary, the borrower shall identify the necessary corrective actions, and reflect them in a corrective action plan. Borrower shall prepare and submit to ADB semi-annual environmental monitoring reports that describe progress with implementation of the EMP and compliance issues and corrective actions, if any. For subprojects likely to have significant adverse environmental impacts during operation, reporting will continue at the minimum on an annual basis until ADB issues a project completion report. 58. Unanticipated Environmental Impacts. Where unanticipated environmental impacts become apparent during subproject implementation, ADB SPS requires the borrower to update the environmental assessment and EMP or prepare a new environmental assessment and EMP to assess the potential impacts, evaluate the alternatives, and outline mitigation measures and resources to address those impacts. 59. Occupational Health and Safety. ADB SPS requires the borrower8 to ensure that workers9 are provided with a safe and healthy working environment, considering risks inherent to the sector and specific classes of hazards in the subproject work areas, including physical, chemical, biological, and radiological hazards. Borrower shall take steps to prevent accidents, injury, and disease arising from, associated with, or occurring during the course of work, including:

7 Per ADB SPS, 2009, meaningful consultation means a process that (i) begins early in the project preparation stage and is carried out on an ongoing basis throughout the project cycle;1 (ii) provides timely disclosure of relevant and adequate information that is understandable and readily accessible to affected people; (iii) is undertaken in an atmosphere free of intimidation or coercion; (iv) is gender inclusive and responsive, and tailored to the needs of disadvantaged and vulnerable groups; and (v) enables the incorporation of all relevant views of affected people and other stakeholders into decision making, such as project design, mitigation measures, the sharing of development benefits and opportunities, and implementation issues

8 In case where responsibility is delegated to subproject contractors during construction phase, borrower shall ensure that the responsibilities on occupational health and safety are included in the contract documents

9 Including nonemployee workers engaged by the borrower/client through contractors or other intermediaries to work on project sites or perform work directly related to the project’s core functions.

57

(i) identifying and minimizing, so far as reasonably practicable, the causes of potential hazards to workers; (ii) providing preventive and protective measures, including modification, substitution, or elimination of hazardous conditions or substances; (iii) providing appropriate equipment to minimize risks and requiring and enforcing its use; (iv) training workers and providing them with appropriate incentives to use and comply with health and safety procedures and protective equipment; (v) documenting and reporting occupational accidents, diseases, and incidents; and (vi) having emergency prevention, preparedness, and response arrangements in place. 60. Community Health and Safety. ADB SPS requires the borrower to identify and assess risks to, and potential impacts on, the safety of affected communities during the design, construction, operation, and decommissioning of the subproject, and shall establish preventive measures and plans to address them in a manner commensurate with the identified risks and impacts. 61. Physical Cultural Resources. Borrower is responsible for siting and designing the subproject to avoid significant damage to physical cultural resources. ADB SPS requires that such resources likely to be affected by the subproject are identified, and qualified and experienced experts assess the subproject’s potential impacts on these resources using field-based surveys as an integral part of the environmental assessment process. When the designed location of a subproject component is in areas where physical cultural resources are expected to be found as determined during the environmental assessment process, chance finds procedures shall be included in the EMP (Appendix 11).

62. ADB SPS International Best Practice Requirements. ADB SPS requires that, during the design, construction, and operation of the project, the executing agency shall apply pollution prevention and control technologies and practices that are consistent with international good practice, as reflected in internationally recognized standards such as the World Bank Group’s Environment, Health and Safety Guidelines. (IFC’s General EHS Guidelines10 and Sector Specific [Water and Sanitation] Guidelines).11 These standards contain performance levels and measures that are normally acceptable and applicable to projects. These standards contain performance levels and measures that are normally acceptable and applicable to projects. When Government of India regulations differ from these levels and measures, the PMU and PIUs will achieve whichever is more stringent. If less stringent levels or measures are appropriate in view of specific project circumstances, the PMU and PIUs will provide full and detailed justification for any proposed alternatives that are consistent with the requirements presented in ADB SPS. The IEEs shall also reflect meaningful consultation and disclosure process with a provision for grievance redress mechanism. B. National and State Laws

63. The implementation of the subprojects will be governed by Government of India and State of Tripura and other applicable environmental acts, rules, regulations, and standards. These regulations impose restrictions on the activities to minimize or mitigate likely impacts on the environment. It is the responsibility of the project executing and implementing agencies to ensure

subprojects are consistent with the legal framework, whether applicable international, national, state or municipal or local. Key standards include those related to drinking water quality, air quality, and protected areas. Compliance is required in all stages of the subprojects including design, construction, and operation and maintenance. 64. Environmental Assessment. The GoI EIA Notification of 2006 (replacing the EIA Notification of 1994), sets out the requirement for Environmental Assessment in India. This states that Environmental Clearance (EC) is required for specified activities/projects, and this must be obtained before any construction work or land preparation (except land acquisition) may commence. Projects are categorized as A or B depending on the scale of the project and the nature of its impacts. 65. Category A projects requires EC from the central Ministry of Environment, Forests and Climate Change (MoEFCC). The proponent is required to provide preliminary details of the project in the prescribed manner with all requisite details, after which an Expert Appraisal Committee (EAC) of the MoEFCC prepares comprehensive Terms of Reference (ToR) for the EIA study. On completion of the study and review of the report by the EAC, MoEFCC considers the recommendation of the EAC and provides the EC if appropriate. 66. Category B projects require environmental clearance from the State Environment Impact Assessment Authority (SEIAA). The State level EAC categorizes the project as either B1 (requiring EIA study) or B2 (no EIA study) and prepares ToR for B1 projects within 60 days. On completion of the study and review of the report by the EAC, the SEIAA issues the EC based on the EAC recommendation. The Notification also provides that any project or activity classified as category B will be treated as category A if it is in whole or in part within 10 km from the boundary of protected areas, notified areas or inter-state or international boundaries. 67. None of the components of up gradation of major roads subproject in Agartala falls under the ambit of the EIA Notification 2006, and, therefore EIA Study or EC is not required for the subproject.

68. Applicable environmental regulations. Besides EIA Notification 2006, there are various other acts, rules, policies and regulations currently in force in India that deal with environmental issues that could apply to infrastructure development. The specific regulatory compliance requirements of the subproject are shown in the below Table 9.

International Convention

Description Requirements

International Union for Conservation of Nature and Natural Resources - 1st July 1975

The International Union for Conservation of Nature and Natural Resources (IUCN) Red List of Threatened Species (also known as the IUCN Red List or Red Data List), founded in 1963, is a comprehensive inventory of the global conservation status of plant and animal species. The IUCN is an authority on the conservation status of species. A series of Regional Red Lists are produced by countries or organizations, which assess the risk of extinction to species within a political management unit. The IUCN Red List is set upon precise criteria to evaluate the extinction risk of thousands of species and subspecies.

These criteria are relevant to all species and all regions of the world. The aim is to convey the urgency of conservation issues to the public and policy makers, as well as help the international community to try to reduce species extinction. Not relevant to the target area of subproject.

Convention on Migratory Species of Wild Animals – 1st November 1983

The Convention on Migratory Species of Wild Animals (CMS) was adopted in 1979 and entered into force on 1 November 1983. CMS, also known as the Bonn Convention, recognizes that states must be the protectors of migratory species that live within or pass through their national jurisdictions, and aims to conserve terrestrial, marine and avian migratory species throughout their ranges.

CMS Parties strive towards strictly protecting these species, conserving or restoring the places where they live, mitigating obstacles to migration and controlling other factors that might endanger them. Not relevant to the target area of subproject.

Convention on International Trade in Endangered Species of Wild Fauna and Flora – March 1973

The Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) is an international agreement between governments. Its aim is to ensure that international trade in specimens of wild animals and plants does not threaten their survival. CITES were first formed, in the 1960s. Annually, international wildlife trade is estimated to be worth billions of dollars and to include hundreds of millions of plant and animal specimens. The trade is diverse, ranging from live animals and plants to a vast array of wildlife products derived from them, including food products, exotic leather goods, wooden musical instruments, timber, tourist curios and medicines. Levels of exploitation of some animal and plant species are high and the trade in them, together with other factors, such as habitat loss, is capable of heavily depleting their populations and even bringing some species close to extinction.

Many wildlife species in trade are not endangered, but the existence of an agreement to ensure the sustainability of the trade is important to safeguard these resources for the future. Because the trade in wild animals and plants crosses borders between countries, the effort to regulate it requires international cooperation to safeguard certain species from over-exploitation. Not relevant to the subproject area.

Ramsar Convention, 3rd February 1971.

The Ramsar Convention is an intergovernmental treaty that provides the framework for national action and international co-operation for the conservation and wise use of wetlands and their resources. India is one of

V. DESCRIPTION OF ENVIRONMENT

A. Physical Resources

1. Location, Area and Connectivity 72. Agartala, the capital of Tripura, is situated along 23° 45’ 23° 55’ N latitude and 91°15’ 91°20’ E longitude, in the flood plains of the Haora River. Historically, the city has been an

71

important border-trading town with trading linkages with Bangladesh. Agartala is the second-largest city in northeast India after Guwahati. The city is governed by the Agartala Municipal Corporation. It is located on the banks of the Haora River, near the Bangladesh border, about 90 km (55 mi) east of Bangladesh's capital Dhaka. 73. Administrative Boundaries: Agartala is the capital of Tripura, the third smallest Indian state considered as the gateway to the North-Eastern India. The Agartala Municipal Corporation (AMC) was established in 1871 with an area of only 3 km2. Presently the extended limit of AMC covers an area of 62 km2 comprising of 35 wards. The Greater Agartala Planning Area (GAPA) is spread over an area of 92.0 km2. It comprises of AMC and eight other villages with population of more than 4 lakhs. Considering the natural geographical division created by the Haora River and Katakhal channel, the GAPA has been demarcated to distinguish the three (3) zones: the north zone, central zone and south zone.

74. Road, Rail and Air Connectivity: The National Highway (NH)-44 connects Agartala with Silchar, Guwahati and other towns of Assam. The city has its own airport and direct flights from many other cities of India for the Agartala Airport. The city also has a very prominent and busy railway station, which connects it with all the major cities of the country. The intercity transportation of Agartala is very well organized too. All the places in the city are easily connected by a well laid network of roads such as VIP road, Pragati Road, Akhaura Road and others. There are buses and other transportations that run in the city all day long. Some important localities in the city include Hrishi Colony, Abhoy Nagar, Ram Nagar, Manipuri Basti, Banamalipur and Shib Nagar.

2. Topography, Soils and Geology

75. Topography: -The major part of the City (Central Agartala) has a flat terrain. However, the North and South Zones have a rolling terrain with average altitude varying from a high of 25 to 30 m to a low of 8 m. Greater Agartala is a combination of plain and undulated areas. The central zone is a flat land bounded by the rivers Haora in the south and Katakhal in the north. An important characteristic of the central part of the city is that it is located at a lower level than other areas giving it the appearance of a saucer. Due to its saucer shape, the low-lying areas are vulnerable to inundation during monsoons. 76. Soils: - The plains of Haora River are alluvial in nature consisting of sand, silt and clay. The soil in Agartala is in general of poor to medium quality. It is characterized by a top soil underlain by a soft to medium/stiff, silty clay/clayey silt layer, which follows a moderately dense to very dense silty sand layer. Bearing capacity of soil is poor and usually is of the range of 4 – 6 tons per m Central Agartala and most parts of south Agartala.

77. Geology: -The geology of Agartala is represented by the repetitive succession of sedimentary rock like sandstone, shale and clay from bottom to top, belonging to Surma group, Tipam group and Dupitila group. The valley is dominated by thick sandstones horizons with thin intervening shale/clay horizons. The sedimentary rocks are deformed and folded. The sandstones are highly porous underlain by impermeable shales or clay and are favorable for ground water retention.

3. Natural Disasters

72

78. Cyclone.12 The District is completely prone to cyclonic hazard zone and the probability of damage is very high. The seasonality of occurrence of cyclone are during the month of October & November. Sometimes the cyclonic wind flows in the state after passing Bangladesh. In such events weakly built houses suffer the damage. Cyclones also disrupt power supply, telecommunication, surface communication and it damages agricultural crops and greenery in the District 79. Seismicity.13 The District is a part of the most severe seismic zone in the country namely Zone-V of seismic zoning map of India. Several number of moderate to large magnitude earthquake occurred within the District. In 1897 and earthquake took place in the state where the State’s only one building that is the king palace which was damaged completely. Several landslide and liquefaction took place in the district. 80. Floods. The District faces flash flood annually during the monsoon season i.e. June to September. Howrah and Kathakhal rivers are two major drainage channels draining flood water to Bangladesh. Now a days due to climate change effect there are irregular raining resulting temporary flooding occur in the low-lying area in District. The city is facing frequent floods also due to blockage of drainage system.

4. Climatic Conditions

81. The climate of Tripura exhibits a strong seasonal rhythm. The state is characterized by a warm and humid tropical climate with five distinct seasons, namely, spring, summer, monsoon, autumn and winter. Spring starts from late mid-February & continues till mid-March. Winter returns if there is rain a fresh in mid-February. Summer season starts from middle of March and reaches its peak in April - May. The monsoon generally breaks in the later part of May or first week of June and lasts till September. 82. Winter sets in from November and is severe in the month of January minimum temperature recorded is 4ºc in January 1995. Humidity is generally high throughout the year. In the summer season the relative humidity is varied from 50 percent to 74 percent whereas in the rainy season it is over 85 percent. 83. Relatively high temperature, occasional thunderstorms and wind velocities characterize the summer season, which extends from March end to mid-May. The average maximum temperature is 34ºC and average minimum temperature is 15ºC. Annual rainfall ranges from 1922 mm to 2855 mm. 84. On-site monitoring was undertaken for various meteorological variables to generate the site-specific data. Data was collected at site every hour continuously from 20th December 2018 to 7th January 2019. 85. Methodology. Site specific data covering micro-meteorological parameters were recorded on hourly basis during the study period and comprises of parameters like wind speed, wind direction (from 0 to 360 degrees), temperature, relative humidity, atmospheric pressure,

12 District Disaster Management Plan 2016-2017 13 District Disaster Management Plan 2016-2017

73

rainfall and cloud cover. The monitoring was carried out at two locations; Pratapgarh (21st-28th December 2018) and Agartala Motor Stand (29th December 2018 -5th January 2019).

86. Observations: The minimum, maximum and average values for all the parameters except wind direction are presented in Table 12.

87. Secondary Data (Meteorology): The climate of Agartala is of tropical monsoon type. The average annual rainfall is around 220 centimeters (cm). The average nos. of rainy days is 100 days. The temperature varies from 4.2°C to 37.6°C on the average. The winter period is from November to February, summer is from March to May and monsoon is from June to September. It has a moderate temperature and highly humid atmosphere. Winds, which are of moderate velocity, are from the south-to-south – east direction for most of the time. Average velocity of wind varies from 4 km to 9 km per hour.

5. Surface Water

88. The drainage system of Agartala is dominated by Haora river and Katakhal Channel, which drains the core area of the city. These two waterbodies flow westward into Bangladesh. In terms of catchment area, Haora River is the seventh largest in the Tripura and is the only source of

74

surface water for Greater Agartala. In addition to these two rivers, there are other rivers like Bangeshwar Gang, Debta Gang, Nagichara, Kalapani Charra and its tributaries within Greater Agartala. The Akhaura canal system running along the Akhaura road serves mainly the central area. All rivers are rain-fed and ephemeral in nature and their flow is directly related to rainfall. 89. Surface Water: 7 surface water sources within 10-km radial distance were examined for physico-chemical, heavy metals and bacteriological parameters to assess the effect of industrial and other activities on surface and ground water. The samples were analyzed as per the procedures specified in ‘Standard Methods for the Examination of Water and Wastewater published by American Public Health Association (APHA). These samples were taken as grab samples and were analyzed for various parameters to compare with the standards for drinking water as per IS: 10500. The water sampling locations are listed below in Table 13 below and are shown in Figure 22. The results of the surface water sampling are shown in Table 14.

90. Observations: The result of water quality monitoring shows that most of the parameters are within the limit as prescribed by IS: 10500. At few locations, iron and manganese was found to be in excess. Fecal coliform were also observed in the water which indicated the contamination due to sewage. The iron and manganese in water is due to the geological reasons.

6. Ground Water

91. Ground water Quality: 8 ground water sources within 10-km radial distance were examined for physico-chemical, heavy metals and bacteriological parameters to assess the effect of industrial and other activities on surface and ground water. The samples were analyzed as per the procedures specified in ‘Standard Methods for the Examination of Water and Wastewater’ published by American Public Health Association (APHA). These samples were taken as grab samples and were analyzed for various parameters to compare with the standards for drinking water as per IS: 10500.

94. Parameters of Sampling: - As per Central Pollution Control Board (CPCB) monitoring guidelines Monitoring of Particulate Matter size less than 10 microns (PM10) and Particulate Matter size less than 2.5 microns (PM2.5), Sulphur Dioxide (SO2), Nitrogen Dioxide (NO2) were monitored on 24 hourly basis and for CO were monitored on eight hourly basis. 95. Presentation of Primary Data: - The graphs in Figure 23 give the variation of various parameters across all the 25 locations. The 98 percentile values are denoted in the graphs. Appendix 3 compares the WHO guidelines and GOI standards, in most of the parameters, Government of India’s Standards are more stringent than WHO AAQS (except PM 10 and PM2.5). For SO2, the results are within WHO standards, For NO2, the results are within NAAQS (absence of WHO standards for 24 hrs.), For PM2.5, the results are more than WHO standards, For PM10, the results are more than WHO standards, For CO, the results are within NAAQS (absence of WHO standards). 96. Observation: All the parameters at all the locations are within the permissible limit (SO2-80 µg/m3, NO2-80 µg/m3 PM10- 100 µg/m3, PM2.5- 60 µg/m3and CO-2000 mg/m3) of the National Ambient Air Quality Standards (NAAQS). The highest concentration was found at station 12 near Kargil Chowmuhani, which is also in permissible limits. Kargil Chowmuhani is very congested place and received loads of pollutants from slow moving traffic, this situation will be improved after execution of project.

8. Noise Quality 97. To understand the noise levels in vicinity of proposed subproject roads, 24 hrs continuous noise monitoring was done at 15 locations in the city. The sites are selected considering proximity

83

to sensitive receptor and traffic congestion areas14. Data was recorded using a Lutron sound level meter. The sound level meter was used to record the SPL reading placed in flat terrain at 1.2 to 1.5m above ground level in an open area with minimum obstruction, at least 3m away from sound reflecting sources like walls, matted or tall grasses, shrubs, or wooded areas. The details of the locations are given in Table 18.

98. Observations: 24-hour monitoring was done at each station. Data was recorded using a Lutron sound level meter. The sound level meter was used to record the SPL reading placed in flat terrain at 1.2 to 1.5m above ground level in an open area with minimum obstruction, at least 3m away from sound reflecting sources like walls, matted or tall grasses, shrubs, or wooded areas. The statistical analysis is done for measured noise levels at fifteen (15) locations during summer season. The results show that the noise levels are high during both day and night time for the Commercial, Residential areas. The parameters are analyzed for Lday and Lnight. These results are shown in Figures 24 and 25.

Figure 24: Noise Variation (day)

85

Figure 25: Noise Variation (night)

99. Results: The results show that the noise levels are higher than the standard limits during both day and night time for the Commercial, Residential and Silent Zone Areas, this could be attributed to the high traffic density and mixed type of land use across the city at most of the locations within the Agartala City. 100. Following requirements of ADB SPS, 2009, PMU and PIUs shall apply pollution prevention and control technologies for all the applicable environmental parameters and practices consistent with international good practice. When the Government of India regulations differ from these levels and measures, PMU shall achieve whichever is more stringent. If less stringent levels or measures are appropriate in view of specific subproject circumstances, PMU will provide full and detailed justification for any proposed alternatives that are consistent with the requirements presented in ADB SPS, 2009.

B. Ecological Resources

101. Biodiversity Assessment: A rapid biodiversity assessment of the proposed Upgradation of major roads was done in December 2018 to understand the various facets of biodiversity of the roads and the adjoining area by field survey. Diversity indices provide important information about rarity and commonness of species in a community. It is important to ascertain these indices as they give a quantitative estimate of how good or bad the baseline biodiversity is. For this subproject a 500m buffer area on either side of each road was demarcated. 7 quadrats were laid in various areas according to various type of ecosystem. The floral species were recorded on basis of visual observation. In the study area quadrats of size 10 x 10 m for trees and 5 x 5 m for shrubs/ herbs were laid and the floral species within the quadrat were noted. Data on number of individuals per species was noted. The faunal survey was done based on direct observation/ visual encounter and searching of signs. The study shows that there were 11 species of trees, 29 herbs, 8 shrubs, 4 climbers, 29 Avifauna, 1 reptile and 17 insects were found during the study period. The details of the species are given in Table 19 and 20.

102. Critically Endangered/ Endangered Species: The species designated by the IUCN as Critically Endangered or endangered are potentially found within 50km of the subproject area. The subproject area is an urban area with complete modified habitats with no pristine natural habitat or flora and fauna, but the 50 km surrounding area of the subproject includes many pockets of pristine natural habitats and have ranges of many IUCN designated fauna and flora. The 50 km area includes Natural Habitat like moderate to dense forest, rivers with influence of tidal water

89

from Bay of Bengal. The IBAT results shows following IUCN designated species have their range in 50 km surroundings of project area.

103. Critical Habitats: As per Proximity report generated by the Integrated Biodiversity Assessment Tool (IBAT), there are no Protected Areas and Key Biodiversity Areas within 10 km of the subproject area. Ujjayanta Palace, which is the center of the proposed Upgradation of Major Roads project is taken as reference point for IBAT proximity analysis report generation. The list of protected area and key biodiversity areas as reported by IBAT proximity checklist are given below in Table 21 and 22. The summary of proximity report generated IBAT for 10 Km and 50 Km from the project area are given in Appendix 14. Some species of IUCN Category falling under critical, endangered and vulnerable are observed in the list, within 50 km from the Ujjayanta Palace. The list of species includes species which are in the hilly regions of Baramura hills (25-30kmfrom project site) in the eastern side and the aquatic species of river basins Meghna and Titas (> 10 kms from project site) flowing in the western side. Since the project area is spread only in the exiting urban areas of Agartala city and the activities are limited to only the construction site and allied activities (Batching plant, labour camp etc.) the impact of the project on ecological components will be local in nature and will be limited.

1. Commerce, Industry and Agriculture

106. Tripura’s gross state domestic product for 2004 is estimated at $2.1 billion in current prices. The economy of Tripura is agrarian. More than 50 per cent of its population depends on agriculture for livelihood and contribution of agriculture and allied activities. Tripura is characterized by low income, overwhelming percentage of population below the poverty line, income leakage, and unemployment. The state is predominantly rural in character (85.29%). Average land holding size is 0.97 hectare. 90% of the cultivators are either small or marginal. 107. Trade and Commerce. There are two small industrial estates, with a total number of 36 industrial units and with a total capital investment of INR 56.575 million. Other than the 2 industrial estates, there are 17 other significant industries in Agartala. These industries, as per records, are not in the category of large and medium industries. Wholesale trade in the city is functioning mostly in the Gole Market area and spreads haphazardly mixing with the retail trade. There are 9 markets maintained by AMC within Municipal limits, of which, Battala and Maharaj Ganja Bazaar are the main service and distribution centres of Greater Agartala. 108. Agriculture. Agriculture and allied activities is the mainstay of the people of Tripura and provides employment to about 64% of the population. There is a preponderance of food crop cultivation over cash crop cultivation in Tripura. At present about 62% of the net sown area is under food crop cultivation. Paddy is the principal crop, followed by oilseed, pulses, potato and sugarcane. Tea and rubber are the important cash crops of the State. Handicraft, particularly hand-woven cotton fabric, wood carvings and bamboo products, are also important. The subproject areas are not located in agricultural lands.

109. Housing and Amenities: 98% used houses primarily as residences while less than 2% had residence cum other use. 65.5% of the households lived in good condition houses, 29.4% in livable houses and about 3% in dilapidated houses. 1.9% used residence cum other use. Census households by type of structure for 56.3% of households were permanent and for 42.3% were semi-permanent and temporary were less than 1%. In terms of availability of Latrines, 98% of the households reported having latrines within the premises. 47.7T households Flush/pour flush latrine connected to septic tank. Only 9.4% of the households had piped sewer system. 28.2% had pit latrine with slab ventilated improved pit and 7 % had pit latrine without slab in open pit. For assets available at household level, 82.9 % had televisions and 67.9% had mobile phones, 42.6% owned bicycles, 23.6% reported owning motorcycles and 5.9% had car/jeep or van. 7.5% households owned TV, Computer/ Laptop, Telephone/mobile phone and Scooter/ Car. 110. Health and Educational Facilities There are good educational facilities in Tripura state, which serve both Agartala urban people and inhabitants of surrounding villages and towns in the hinterland. There are about 21 colleges in Agartala comprising Medical college, Degree college, Nursing college, Polytechnic college and Open university. Percentage of literacy according to 2011 census is 93.88, higher than the national literacy rate. There are also 9 nos. nursing home and hospital at Agartala. One Government Medical College is also located at Agartala 111. Educational Institutions: Agartala being a well-developed city and capital of the state, it is home to several educational institutions and this can be easily seen in the map given here. Some of the educational institutions in the city include B.Ed. College, Hindi H.Sec School, Ram Nagar School, Bijoy Kumar School, MTB Girls School, Vani Vidyapeeth, Government Women's College, Govt. Law College among others. D. Social and Cultural Resources

112. Demography: - The total estimated population of AMC limits as per 2011 census is 3,99,668. Population density of GAPA increased to 41% person per hectare in the year 2001 in compared to 38% in 1991. There are two major racial groups, namely the Indo-Aryans represented by the Bengalis and the Indo-mongoloid represented by communities like the Tripuris, the Reangs, the Noatis, the Kukis, the Halams, the Chakma, the Mogh and the Lushai. The percentage of Scheduled Tribe population to the total city population is estimated to be around 4%. The scheduled tribe populations living in the city is well integrated with the mainstream and is gainfully employed. The literacy rate in Agartala is the highest among the localities of Tripura. 113. History, Culture and Tourism: One of the earliest kings of Tripura was Patardan B.C. 1900, long before the Manikya Dynasty. According to folklore, Chitrarath, Drikpati, Dharmapha, Loknath Jivandharan were important kings during the time of B.C. in Agartala. 114. In the past, Tripura served as the capital to several Hindu kingdoms. Although a timeline of the rulers has not been found, records reveal that the area has been ruled by as many as 179 Hindu rulers, starting from the mythological King Druhya to the last King of Tripura, Kirit Bikram Kishore Manikya. Tripura also came under Mughal rule. The state came under the governance of the British in 1808. Much later the ancient capital of the then Princely State 'Swadhin Tripura' was at Rangamati (Udaipur, South Tripura) by the bank of the river Gomati. In 1760 it was shifted by the Maharaja Krishna Chandra Manikya Bahadur (r.1829–1849) of Manikya Dynasty to present old Agartala by the bank of the river Haora/Saidra and was named 'Haveli'. Due to frequent invasion of the Kukis and also to keep easy communication with the British Bengali, the Maharaja Krishna Chandra Manikya started the process of shifting the capital from Old Haveli to New Haveli (present Agartala) in 1849.

93

115. During the British Raj, Agartala was the capital of the 'Hill Tippera' state, it became a municipality in 1874–75, and in 1901 had a population of 9,513. The princely state always remained as cake piece to the British and many other invaders. For example, when Arakhan soldiers attacked the old capital of the state the king of Tripura responded by defeating the entire troop. The Agartala Municipality was established during the reign of Maharaja Bir Chandra Manikya (1862–1896) within an area of 3 square miles (8 km2) having a population of only 875 by a royal proclamation in the last part of 1871. A.W.S. Power, the first British political agent for Tipperah was also appointed as the Chairman of the Agartala Municipality in 1872 who held office from 1872–73. The municipality located at the crossing of latitude N 23° 50' and longitude E 91°17' covering 3 km2. Area during that period. E. Physical Cultural Resources

116. Ujjayanta Palace is a representative example of neoclassical style of early 20th century designed by Sir Alexander Martin for Maharaja Radha Kishore Manikya. The complex of site area 800 acres comprises of the two storied Palace building with central dome, symmetrically landscaped grand entrance promenade in between two ponds, Chhatris, Rear garden, North gate and Astabal. 117. The palace has historical association to the Manikya dynasty, the rulers of Tripura before merger into India. Ujjayanta palace presently accommodates the State Museum of Tripura from 2011, formerly being used as State Legislative Assembly. The site has provided opportunities for tourist attraction, knowledge source and social cohesion, as it also accommodates the Tourism Department office and a restaurant. 118. It is a Landmark structure in the city of Agartala with significant architectural, aesthetic, cultural value and huge associational value with the inhabitants of the state. It provides contextual value as it is historically and visually linked to its surroundings. PCRs along the project roads 119. Agartala has plenty of religious and cultural places. Though Hinduism is the main religion of the place, other religions like Islam, Buddhism and Christianity are also having their place. The city has a lot of temples, churches, mosques and monastery, some of which are over 150 to 200 years old. Some of the famous religious institutions include Buddha Mandir, Mother Theresa Ashram and Ramakrishna Ashram Vidyamandir among many others. The city has a Universal Prayer Hall, where people can come and pray.

VI. ANTICIPATED ENVIRONMENTAL IMPACTS & MITIGATION MEASURES

A. Introduction

123. Potential environmental impacts of the proposed infrastructure components are presented in this section. Mitigation measures to minimize/ mitigate negative impacts, if any, are recommended along with the agency responsible for implementation. Monitoring actions to be conducted during the implementation phase is also recommended to reduce the impact. 124. Screening of potential environmental impacts are categorized into four categories considering subproject phases: location impacts and design impacts (pre-construction phase), construction phase impacts and operations and maintenance phase impacts.

(i) Location impacts include impacts associated with site selection and include loss of on-site biophysical array and encroachment either directly or indirectly on adjacent environments. It also includes impacts on people who will lose their livelihood or any other structures by the development of that site.

(ii) Design impacts include impacts arising from Investment Program design, including technology used, scale of operation/throughput, waste production, discharge specifications, pollution sources and ancillary services.

(iii) Construction impacts include impacts caused by site clearing, earthworks, machinery, vehicles and workers. Construction site impacts include erosion, dust, noise, traffic congestion and waste production.

(iv) O & M impacts include impacts arising from the operation and maintenance activities of the infrastructure facility. These include routine management of operational waste streams, and occupational health and safety issues.

125. Screening of environmental impacts has been based on the impact magnitude (negligible/moderate/severe – in the order of increasing degree) and impact duration (temporary/permanent). 126. This section of the IEE reviews possible project-related impacts, in order to identify issues requiring further attention and screen out issues of no relevance. ADB SPS (2009) require that impacts and risks will be analyzed during pre-construction, construction, and operational stages in the context of the project’s area of influence. 127. The ADB Rapid Environmental Assessment Checklist for urban development has been used to screen the project for environmental impacts and to determine the scope of the IEE. 128. The IEE study should evaluate impacts due to the location, design, construction and operation of the project. The proposed project would create an impact on the environment in three distinct phases:

(i) Design phase (ii) During Pre-Construction phase (iii) During the Construction phase, which may be considered as temporary or short

term; (iv) During the Operation and Maintenance phase, which would have long term effects

B. Design Impact

115

129. The proposed design for the subproject includes construction of roads, drains, utility ducts and pathways. The subproject road involves construction of utility ducts and trenches for drainage lines, water supply lines, electricity and telecommunication cables and gas pipelines. The IRC: 98-1997, Guidelines on accommodation of utility services on roads in urban areas is followed. Various design features that will improve the existing condition of the roads are as follows:

(i) Storm water drain is provided at the extreme edge of the right of way. (ii) Water supply lines carrying water at high pressure may cause damage to the road

pavement, so they are provided on one side of the road. (iii) There is safe distance between water supply line and drainage line to avoid any

intermixing in case of any leakage or pipe burst. (iv) Electric cables are kept away from water supply lines to avoid short circuit. (v) HT cables are kept away from the telecommunication and ICT cables to avoid any

possible electrical interference due to induced voltage. (vi) The cables are away from tree line to avoid possible entrapment of the cable by

tree roots. (vii) Footpaths and zebra crossings are provided cater the needs of elderly and persons

with disability. (viii) The roads are provided with LED streetlights and other fixtures for better lighting

and safety of motorists, riders and pedestrians. (ix) Gas pipeline is located far away from the electricity cables and sources of heat. (x) Concrete ducts are designed to carry the utilities in groups to minimize the

inconvenience of frequent digging of the road at different locations for repairs and maintenance.

(xi) The IS- 1255-1983 (Code of Practice for Installation and Maintenance of Power Cables Up-to and including 33 kV Rating) is followed, based on this the minimum safe distance between power cable to control cables is considered as 0.2m, distance between Power cable and communication cable is kept at 0.3m and the distance between Power Cable and gas/ water main is maintained at more than 0.3m in the design concept.

130. Visual Improvement: Roads considered under proposed project are planned to have dedicated footpaths with street furniture, tree belt and landscaping, smart road elements such as smart light poles, WIFI and CCTV poles, smart traffic signals, and parking, etc. Services are designed underground to increase the visual aesthetic in coordination with ICT components being proposed. This will not only enhance the overall visual features of the proposed roads also improve the overall aesthetics of Agartala city and it will be a positive impact to the city and its people. 131. Safety in Design: Agartala city faces problems of flash flood. Issues of inundations are reported after heavy rainfall across the city and mainly in the low-lying areas. Mitigation measures provided are follows:

(i) There are storm water pumping stations to pump and dispose the flood water into Katakhal or Haora rivers to address the problem of flash flood.

(ii) Under the Smart City proposal seven existing storm water pumping stations along the subproject roads are enhanced to mitigate the flash flood issues at, 1) IGM Chowmuhani, 2) Orient Chowmuhani, 3) Gangaraj Chowmuhani, and 4) Old Motor stand 5) Dhaleshwar 6) Indranagar 7) Ranjith Nagar.

C. Pre-Construction Phase Impacts

116

132. Location Impacts: It Includes impacts associated with site selection, loss of on-site biophysical properties. 133. Site Selection of construction work camps, stockpile areas, storage areas and disposal areas: During the project pre-construction (site clearing) and construction stage, priority is to locate the construction work camps, stockpiles areas, storage areas and disposal areas near the project locations. However, if it is necessary to re-locate elsewhere, sites to be considered will not result in destruction of property, vegetation, irrigation, and drinking water supply systems. Residential areas will not be considered for setting up camps to protect the human environment (i.e., to curb accident risks, health risks due to air and water pollution and dust, and noise, and to prevent social conflicts, shortages of amenities, and crime). Extreme care will be taken to avoid disposals near the forest, water bodies, swamps, or in areas which will inconvenience the community. Material stockpiles shall be protected by bunds during the monsoon to arrest the silt laden runoff into drains. The subproject is likely to generate soil from excavations, which needs to be disposed safely. The mitigation measures for handling of soil, excavated earth material and other construction wastes will be as follows: 134. Mitigation Measures:

(i) The excavated soil should be removed from construction area at the earliest for beneficial reuse such as land raising/ filling of excavated areas.

(ii) Soil should be covered with tarpaulin sheets during transportation. (iii) Soil transportation should not be done during peak hours and should be avoid

narrow and heavy traffic routes and important religious or tourist sites etc. (iv) Earthen bund to be provided around the storage areas for excavated soil and other

construction material. (v) Completed earthworks to be sealed and/or re-vegetated at the earliest with the

help of landscape expert.

135. Site Selection for Source of Materials: The material used for the construction of subproject components are mainly sand, coarse aggregate fine aggregate and gravel for construction works. Extraction of materials can disrupt natural land contours and vegetation resulting in accelerated erosion, disturbance in natural drainage patterns, ponding and water logging, and water pollution. 136. The natural raw materials like sand, gravel and soil shall be procured/ sourced from the authorized mines listed by Tripura Government as specified in the website http://trpenvis.nic.in/test/natural_resources.html. For material like gravel and bituminous macadam that are not available in the state, the contractor shall ensure that it shall be procured/ sourced from authorized mines listed by the respective state government website. The transportation of raw material from other states may cause trans-boundary pollution leading to air and noise pollution. 137. Mitigation Measures:

(i) Contractor should procure these materials only from the quarries permitted/ licensed by Mines and Geology Department, Government of Tripura;

(ii) Contractor should, to the maximum extent possible, procure material from existing authorized quarries;

(iii) The contractor shall try to procure/ source the material from the nearest possible authorized mines.

117

(iv) It will be the construction contractor’s responsibility to verify the suitability of all material sources and to obtain the approval of Department of Mines & Geology and local revenue administration; and

(v) Contractor should submit the details of sources and copies of approvals, permissions to AMC, and should start procurement only after the respective source is approved by AMC.

(vi) The transportation of raw material should be done in covered vehicles. (vii) The vehicles used for the transportation of raw material should have valid PUC

certificate and should be well maintained to avoid noise pollution.

138. Tree cutting: The total number of trees to be cut, falling within the RoW of the proposed project is about 520, road-wise details are given in Table 26. Total numbers of species of trees found in the RoW is 38 (list given in Table 27) with maximum trees of the category of avenue plantation. About 50% of the trees are either raintree or Radha-chura species of trees which are common avenue plantation species. No rare or endangered species of plants are found in the list of trees falling within the RoW. The list of road-wise trees with their species and girth is being surveyed by the Forest Department are given in the Appendix 16. 139. Mitigation Measures:

(i) The contractor shall take necessary steps to safeguard the trees and reduce the number of trees to be cut during the time of construction.

(ii) All possible measures should be taken to avoid cutting trees with more than 300 cm girth size (around 20 nos. of trees). This can be done by diverting the utility ducts and drains during the implementation stage.

(iii) Safeguarding these trees will be ensured from the contractor by Nodal Environmental Safeguard Officers of PMU and PMC.

140. Compensatory plantation: Details on compensatory plantations were sought from Forest Department vide ASCL letter no. F.4(34)/ASCL/2018/917 dated 19-02-2020 (letter attached in Appendix 15). Forest Department in its Letter no. F.11-13/WFD/Deptt.0prnt/2018-19/11595-597 dated 27-02-2020 (letter attached in Appendix 16) informed that compensatory plantation is done for twice the number of trees to be fell.

141. Based on the ecological assessment, 29 species of birds are found along the proposed road stretches (the details are given in Table 20). The cutting of trees disturbs the nesting and breeding of birds due to the destruction in their habitat. The cutting of trees during the nesting and breeding season shall be avoided and contractor shall check for nests before cutting the trees.

142. Utilities: Telephone lines, electric poles and wires, water lines within the proposed subproject locations may require to be shifted in few cases. To mitigate the adverse impacts due to relocation of the utilities, the following measures will be followed:

143. Mitigation Measures:

(i) Identify and include locations and operators of these utilities in the detailed design documents to prevent unnecessary disruption of services during construction phase;

(ii) Conduct detailed site surveys with the construction drawings and discuss with the respective agencies during the construction phase, before ground clearance;

120

(iii) Require construction contractors to prepare a contingency plan to include actions to be done in case of unintentional interruption of services. In case of disruption of water supply, alternative supply, through tankers, shall be provided.

144. Shifting of transmission line from overhead to underground: The project involves shifting of HT, LT lines and OFC/ communication lines from above ground to underground. There will be total removal of around 1800 nos. electrical poles and 225 nos. transformers for the proposed smart road project. The benefits of Underground lines are:

(i) Reduced risk of power outages and communication disruption from severe storm. (ii) Underground lines can absorb emergency loads, lower transmission loss. (iii) Improved life of transmission and communication lines. (iv) Improvement in aesthetics of the area. (v) Reduce the premature death of wildlife (eg-squirrels. Birds, rodents etc.,).

145. There are environmental impacts of the conversion like:

(i) An increase in area of environmental disturbance. (ii) The complete removal of small trees and bushes along the transmission ROW. (iii) Generation of removed electrical and telephone poles (approximately 1800 nos.)

and around 225 nos. of transformers. (iv) Increase in occupational health and safety risk to utility operational staff.

146. To minimize the following mitigation measures will be implemented:

(i) The alignment is done in such a way to minimize tree cutting, in addition to these, tree will be planted along the median and available spaces in the row.

(ii) The Electrical and Telephone poles will be reused by the Tripura State Electricity Corporation Ltd.,

(iii) The transformer will be reused at other locations and reutilization of streetlamps in other locations.

(iv) Adequate trainings will be provided to the operational staff for occupational health and safety issues.

147. The storage and re-use of electric poles and transformers shall be the responsibility of Tripura State Electricity Corporation Limited (TSECL). A letter dated F.4(28)/TSECL/ Corp.office/ 2018-19/9637-40 dated 29-06-2019 providing No Objection Certificate for storage and reuse of dismantled Electric Poles and transformers recovered during overhead to underground lines conversion work for the subproject roads is received from TSECL, a copy attached as Appendix 4. TSECL officials have confirmed that the transformers used in entire Tripura state are PCB free the details of the consultation are given in Public Consultation chapter.

148. Flooding: The Agartala city faces frequent flooding during monsoon leading to inundation of roads. Some of the proposed subproject roads like HGB Road, Mantribari Road, Shakuntala Road and Thakurpalli Roads face flash flood issues. The storm water drains from Barjala Road, VIP Road, GB Road, Jail Road, Jail Ashram Road, IT hub road are connected to Katakhal Channel. Storm water drains from Akhaura Road, Ronaldsay Road and Part of HGB and GB Roads are connected to Akhaura Channel. Storm water drain of part of HGB road from Old motor

122

stand to Battala junction is connected to Kalapania Khal. The drainage map of proposed roads showing the outfalls are shown in the Figure 28. The catchments of the drains along the proposed roads and its respective outfalls are as per natural gradients. Total quantum of flow from the catchments of roads is about 81.6 cum/ sec, which is very insignificant when compared with the flow in the outfalls points of Katakhal, Akhaura. Further this flow gets distributed at different points and flows into the outfalls without adding to flash floods. The proposed storm drains will act as a medium for efficient conveyance of rain water towards the outfalls that will help in disposal of water.

149. Various mitigation measures are taken to control the flooding issues as enumerated below.

Figure 28: Image showing Drain map of proposed roads

150. Mitigation Measures:

(i) 39.735 km of drain are proposed along the designed roads, to reduce the flooding problems of Agartala.

(ii) The drains proposed in the project are designed with proper gradient and flow conditions. The storm water will not lead to any flood like situation in the city and the channels, as the drain catchments as well as the outfalls remains the same before and after development of the proposed project.

(iii) There are storm water pumping stations to pump and discharge flood water into Katakhal or Akhaura Channel rivers to address the problem of flash flood.

123

(iv) Under the Smart City proposal seven existing storm water pumping stations along the subproject roads are enhanced to mitigate the flash flood issues at, 1) IGM Chowmuhani, 2) Orient Chowmuhani, 3) Gangaraj Chowmuhani, and 4) Old Motor stand 5) Dhaleshwar 6) Indranagar 7) Ranjith Nagar. This will ensure that the proposed project will not enhance the flash flooding issues rather will improve the existing situation.

(v) The proposed drains will be connected to the 3 natural drains, Kalapania khal, Akhaura channel and Katakhal, all these natural channels ultimately lead to _Bay of Bengal through Titas and Meghna river.

151. Preparation of H&S Plan for Pandemic like COVID- 19, With the existing EHS guidelines contracture has to prepare a site specific EHS plan including COVID -19 guidelinesbased on following pinciples and it get approved from PMU before staring of construction, the Contractor shall abide by the most stringent procedure available.

(i) Consistently practice social distancing. (ii) Cover coughs and sneezes. (iii) Maintain hand hygiene. (iv) Clean surfaces frequently.

D. Construction Phase Impacts

152. Screening of non-Significant Impacts: The construction work is expected not to cause major negative impacts, mainly because:

(i) Most of the activities will be on the built-up areas of Agartala city thus could be constructed without causing impacts to biodiversity;

(ii) All the sites are located on a government-owned land which is not occupied or used for any other purpose;

(iii) Overall construction program will be relatively short and is expected to be completed in 24 months with activities to be conducted by small teams and specified location so most impacts will be localized and short in duration; and

(iv) Most of the predicted impacts associated with the construction process are produced because the process is invasive, such as involving excavation. However, the routine nature of the impacts means that most can be easily mitigated, and the impacts are clearly a result of the construction process rather than the design or location, as impacts will not occur if excavation or other ground disturbance is not involved.

153. As a result, there are several aspects of the environment which are not expected to be affected by the construction process and these can be screened out of the assessment at this stage as required by ADB procedure. These are shown in Table 30. These environmental factors are screened out presently but will be assessed again before starting of the construction activities.

Table 30: Fields in which construction is not expected to have significant impacts

Field Rationale

Topography, Drainage, and Natural Hazards

Activities are not large enough to affect these features.

Geology, Geomorphology, Mineral Resources, and Soils

Activities are not large enough to affect these features. No mineral resources in the subproject location.

Climate Activities are not large enough to affect this feature.

124

Field Rationale

Geohydrology and Groundwater Activities will not be large enough to affect these features

Protected Areas No protected areas nearby the Agartala city and project locations

Flora and Fauna No rare or endangered species.

Land Use No change in major land use.

Socio-economic The project is within the existing ROW, hence social impact will be temporary and minor in nature.

Commerce, Industry, and Agriculture Activities are not large enough to affect these features

Population Activities are not large enough to affect this feature.

Health and education facilities Activities are not large enough to affect this feature.

Historical, Archaeological, Paleontological, or Architectural sites

No scheduled or unscheduled historical, archaeological, paleontological, or architectural sites

154. Anticipated Impacts and Mitigation Measures: Although construction of the subproject components involves simple techniques of civil work, excavation and the subproject locations in the built-up areas of Agartala city where there are a variety of human activities, will result in impacts to the environment and sensitive receptors such as residents, businesses, and the community in general. These anticipated impacts are temporary and for short duration. Physical impacts will be reduced by the method of working and scheduling of work, whereby the project components will be (i) constructed by small teams working at a time; (ii) effective traffic management; (iii) planning for utility shifting (iv) any excavation done near sensitive area like school, religious places and house will be protected as per standard norms.15 155. Air Quality: Most of the dust (suspended particulate matter) during construction arises from operations such as excavation and filling during site preparation works, loading, unloading and transportation of construction material, drilling use of heavy equipment’s and machinery in the earthworks and pavement works. The fugitive dust released during the construction activities cause immediate effect on the construction workers as well as on the nearby households, businesses and people residing in these structures. Increased suspended particulate matter and fugitive gaseous emissions like, oxides of Sulphur (SOx), oxides of nitrogen (NOx), carbon monoxide (CO) etc., will be released from vehicles, batching plants and diesel generator sets etc., also add to the problem. Most of the generated pollutants from the above activities are limited to construction phase and confined to construction site due to surrounding buildings and settlement. 156. Mitigation Measures

(i) Dust cannot be avoided completely due to the nature of the activities during site preparation and construction. However, it can be managed by regularly spraying water at the site (particularly during the dry season).

(ii) Stockpiles of raw/ waste material, demolition debris, excavated earth etc., shall be covered with tarpaulin during the entire construction activity.

15 Occupational Health and Safety of employees working only in factories and mines have been specifically covered in GOI laws. However, the Constitution of India has provisions to ensure that the health and well-being of all employees are protected, and the State has the duty to ensure protection. For this subproject, the mitigation measures were based on the World Bank Environmental, Health, and Safety (EHS) Guidelines.

125

(iii) Vehicles carrying demolition debris from site shall be covered with tarpaulins while entering and leaving the site will always be covered.

(iv) Consent to Establishment (CTE) and Consent to Operate (CTO) shall be obtained from TSPCB for construction establishments such as hot mix plants, batching plants and stone crushers if set up by the contractor. All project activities are adhered to the contractual obligations under clearances and approvals

(v) Construction labours shall be provided with nose masks and other personnel protective equipment.

(vi) LPG or low Sulphur diesel shall be used in the Diesel Generator sets and DGs are fitted with the chimney stack of required height.

157. Surface Water: There are some waterbodies adjacent to the VIP road at a distance within 100 m, and the Ponds of Ujjayanta Palace are adjoining the Thakurpalli Road, along with these Rajbari lake, Jagannath bari lake and Banmalipur dighi along Thakurpalli road, Rani pukur along VIP road near Ginger Hotel and Mukta pukur on Akhaura road. There are a few small streams and nallas crossed by the subproject road. Disturbance to flows; alteration of drainage causing erosion; sewage and oil/grease/lubricant contamination from construction camps may occur. 158. Mitigation Measures

(i) Stockpiles shall be at least 5 m from the adjacent pond waters. (ii) Contractor shall ensure that no construction materials like earth, stone, waste

disposed of in a manner that block the flow of water to and from the ponds. Contractor will be required to avoid site cleaning and earth fill especially during the monsoon season unless covered by tarpaulins or plastic sheets.

(iii) Provide temporary bunds for stockpiles and materials. (iv) Prioritize re-use of excess spoils and materials in the construction works. If spoils

will be disposed, consult with PIU on designated disposal areas (v) Place storage areas for fuels and lubricants away from any drainage leading to

water bodies (vi) Dispose any wastes generated by construction activities in designated sites of DC

Nagar Lunga Site. (vii) Install temporary silt traps or sedimentation basins along the drainage leading to

the water bodies. (viii) Avoid spillage or leakage of raw material and fuel, oil etc., in the water bodies.

159. Groundwater Quality: Proposed project activity do not interfere with ground water regime; no ground water usage/ abstraction is proposed, and activities do not affect ground water quality.

160. Noise & Vibration Impacts: All the construction works will be conducted during the day time. Increase in noise level may be caused by excavation, transportation of equipment, materials, and people. Noise is a major area of concern, especially where a number of sensitive receptors are located within Impact zone and close to RoW. The impact on ambient noise due to the project is not of significance during both construction as well as the operation stages. Vibration generated from construction activity, for instance from the use of pneumatic drills, will have impact on nearby buildings. Heavy vehicle movement and equipment usage might also damage fragile buildings if vibration is excessive. This impact is negative but short-term, and reversible by mitigation measures. 161. Mitigation Measures:

126

(i) The construction contractor will be required to plan activities in consultation with Environmental and Social Safeguard officer of PMU and PMC so that activities with the greatest potential to generate noise are conducted during periods of the day which will result in least disturbance

(ii) Construction work shall be limited to day light hours (8 AM to 6 PM) for all the works located within the town

(iii) Provide prior information to the local public about the work schedule (iv) Minimize noise from construction equipment/ pneumatic drills by using silencers,

fitting jackhammers with noise-reducing mufflers (v) The DG sets used for construction activities shall be with acoustic enclosures and

shall meet the latest CPCB standards for noise generation. (vi) Wherever required, personal protective equipment such as ear plugs, earmuffs etc.

shall be provided to the persons working in high noise areas (vii) Personnel Protective Equipment’s (PPE) such as Ear plugs, and earmuffs shall be

provided to the workers operating or working near noise generating machines (viii) Equipping construction equipment engines with adequate mufflers, silencers, and

engine enclosures would reduce their noise by 5 to 10 dB (A). (ix) Turning off construction equipment during the prolonged periods of nonuse

eliminates noise from construction equipment during those periods. (x) Regular maintenance of all equipment and training to equipment operators would

reduce noise levels and increase efficiency of equipment. (xi) Locating stationary equipment away from sensitive receptors would decrease

noise considerably. (xii) Noise barriers will be installed near sensitive receptors of HGB Road and Akhaura

Road where prevalent noise levels are high to reduce the noise level during operation stage. Noise barrier will be installed at IGM Hospital building facing Akhaura Road (~140m), Government Ayurvedic Hospital, HGB Road (~10m) and Kamini Kumar Sangh School, HGB Road (~120m). The costing of the noise barrier is considered in EMP budget.

(xiii) Identify any buildings at risk from vibration damage and avoiding any use of pneumatic drills or heavy vehicles in the vicinity.

162. Generation of Spoil and its Disposal. Some sections of the sub-project roads will cross water bodies, exposing them to risks of pollution caused by: (i) poorly managed construction sediments, and waste materials; and (ii) poor sanitation practices of construction workers. Polluted water bodies will be harmful to aquatic life and people that depend upon such contaminated sources. The impact is thus direct in nature, local to regional in extent, medium in magnitude and short term in duration. 163. Mitigation measures:

(i) Not to dispose any construction materials in river/stream which may pollute the river water and aquatic fauna

(ii) Spoil Disposal Management Plan (SDMP) will be prepared and implemented to minimize the potential effects of sediment plumes on aquatic habitats. Sample spoil management plan is attached as Appendix 5.

(iii) Details of the proposed Water Quality Monitoring Program will be included in the environment management plan.

127

164. Construction and Demolition Waste: Construction debris/ waste is generated due to demolition of existing drains and pathways, scarification of existing pavement and excavation at some section of the subproject road, collection of silt from existing drains proposed to be demolished. Improper disposal of scarified bitumen causes decrease in soil fertility and water pollution. Careless disposal of debris can obstruct waterways causing siltation of reservoirs and reduce capacity. Unleaded demolition wastes will cause traffic blockage and dust causing inconvenience and health risks. 165. The excess C&D waste for construction will be processed at C&D waste management site at DC Nagar Lunga, Therefore the existing C&D processing site is an associated facility as per the ADB Safeguard Policy Statement 2009. Compliance with the environmental safeguards will ensure the subproject sustainability. The Environmental Audit Report of Existing C&D waste Management site at DC Nagar Lunga in Agartala is attached as Appendix 6. 166. An application for Request of NOC for dumping/ storing of Construction and Demolition waste and drain silt in DC Nagar Lunga SWM Site for future reuse is submitted to the AMC office, an approval from AMC is received and is attached as Appendix 7. For management and final disposal of all other solid wastes, the mitigation measures that will be applied are:

167. Mitigation Measures

(i) It is proposed that more than 35% of the construction and demolition waste generated from the subproject roads will be utilized in construction works and the balance amount will be dumped at the DC Nagar Lunga site owned by AMC, from where the waste could be re-used for future construction activities.

(ii) The silt collected from drains will be disposed on authorized waste management site at DC Nagar Lunga Site.

(iii) Out of the total excavated earth 25% will be reused in construction works and the rest will be stored as the DC Nagar Lunga site for future use

(iv) collection of recyclable solid wastes and supply to scrap vendors (v) ensure all the camp wastes and construction wastes are placed in the designated

waste collection pits away from receiving water. (vi) establishment of separate bounded areas for the collection and storage of all the

toxic material wastes, including batteries, oil filters, mobile, burnt oils, etc. at the construction site

(vii) collection of biodegradable wastes in separate vessels and transfer to municipal waste disposal system.

(viii) application of various waste disposal systems for diverse wastes produced on site as per consultations with environmentalists.

168. Impact on Accessibility. Hauling of construction materials and operation of equipment on-site can cause traffic problems. The subproject roads are 2 to 4 lanes roads and during construction stage part diversion will be planned to reduce the accessibility problem to the residents, except for the road stretch between Ker Chowmuhani to TUTCL which is about 500m where due to very narrow width complete closure and diversion will be planned. Potential impact is negative but short term and reversible by mitigation measures. 169. Mitigation Measures:

(i) Plan transportation routes so that heavy vehicles do not use narrow local roads, except in the immediate vicinity of delivery sites;

128

(ii) Schedule transport and hauling activities during non-peak hours; (iii) Locate entry and exit points in areas where there is low potential for traffic

congestion; (iv) Keep the site free from all unnecessary obstructions; (v) Drive vehicles in a considerate manner; (vi) Coordinate with Govt. Traffic Department for temporary road diversions and with

for provision of traffic aids if transportation activities cannot be avoided during peak hours; and Notify affected sensitive receptors by providing sign boards informing nature and duration of construction works and contact numbers for concerns/complaints. Sample Traffic Management Plan is attached as Appendix 8.

170. Socio-Economic – Income. The subproject components will be in existing RoW. Construction works will hinder the access of residents to households and customers to the shops and commercial establishments, places of worship, hospital, schools etc., for a period of 7-15 days’ time during the excavation and trenching activities. This will have a negative impact on the income of the shopkeepers and owners of commercial establishments on the subproject roads temporarily. Total number of shops which require access during the construction have been surveyed and presented in the Table 31 171. Mitigation Measures:

(i) Each of these households and shops shall be provided with safe and secure Mild Steel (MS) ramps with handrails for access, the indicative diagram specific to the proposed project is given in the Figure 29.

(ii) To reduce prolonged disruption of livelihood of commercial establishments, the drain stretches of two roads having high commercial activities are being replaced with precast drains. The stretches are in Sakuntala Road (Sakuntala Road to Jackson gate chowmuhani – 200 m length each on both side) and HGB Road (Post office chowmuhani to old motor stand – 720 m each on both side).

(iii) Increase workforce in front of critical areas such as institutions, place of worship, business establishment, hospitals, and schools;

(iv) Consult businesses and institutions regarding operating hours and factoring this in work schedules;

(v) No shops are envisaged to be damaged due to the proposed road works, however, if any damage is anticipated during construction, suitable design changes and diversion arrangements shall be made to avoid the damages and

(vi) Provide sign boards for pedestrians to inform nature and duration of construction works and contact numbers for concerns/complaints.

172. Socio-Economic – Employment. Manpower will be required during the 24-months construction stage. This can result to generation of contractual employment and increase in local revenue. Thus, potential impact is positive and long-term. 173. Mitigation Measures:

(i) Employ at least 50% of the labour force, or to the maximum extent, local persons within the 2-km immediate area if manpower is available; and

(ii) Secure construction materials from local market.

174. Occupational Health and Safety. Workers need to be mindful of the occupational hazards which can arise from working in height and excavation works. Potential impacts are negative and long-term but reversible by mitigation measures. The construction contractor will be required to Designate a safeguard focal person and undertake safeguards orientation by ASCL/ PIU.

130

175. Mitigation measures:

(i) Comply with all national, state and local labor laws ; (ii) Following best practice health and safety guidelines: IFC’s General EHS

Guidelines,16 WHO Interim Guidance (and its updates) on Water, Sanitation, Hygiene and Waste management for the COVID19 virus (Appendix 19), and Sector Specific (Water and Sanitation) Guidelines;17

(iii) Develop and implement site-specific Health and Safety (H and S) Plan which will include measures such as: (a) excluding public from the site; (b) ensuring all workers are provided with and use Personal Protective Equipment; (c) H and S Training18 for all site personnel; (d) documented procedures to be followed for all site activities; and documentation of work-related accidents;

(iv) Strict compliance of H&S plan and requirements of wearing personal protective equipment (PPE) during work hours;

(v) Provide specific guidance for suitable PPE for every on-site work assignment. (vi) Ensure that qualified first-aid is provided at all times. Equipped first-aid stations

shall be easily accessible throughout the site; (vii) Provide medical insurance coverage for workers; (viii) Secure all installations from unauthorized intrusion and accident risks; (ix) Provide supplies of potable drinking water; (x) Provide clean eating areas where workers are not exposed to hazardous or

noxious substances; (xi) Provide H&S orientation training to all new workers to ensure that they are

apprised of the basic site rules of work at the site, personal protective protection, and preventing injuring to fellow workers;

(xii) Provide visitor orientation if visitors to the site can gain access to areas where hazardous conditions or substances may be present. Ensure also that visitor/s do not enter hazard areas unescorted;

(xiii) Ensure the visibility of workers through their use of high visibility vests when working in or walking through heavy equipment operating areas;

(xiv) Ensure moving equipment is outfitted with audible back-up alarms; (xv) Mark and provide sign boards for hazardous areas such as energized electrical

devices and lines, service rooms housing high voltage equipment, and areas for storage and disposal. Signage shall be in accordance with international standards

16https://www.ifc.org/wps/wcm/connect/554e8d80488658e4b76af76a6515bb18/Final%2B-%2BGeneral%2BEHS%2BGuidelines.pdf?MOD=AJPERES

18 Some of the key areas that may be covered during training as they relate to the primary causes of accidents include (i) slips, trips and falls; (ii) personal protective equipment; (iii) ergonomics, repetitive motion, and manual handling; (iv) workplace transport; and (v) legislation and responsibilities. Training can provide the foundations of competence, but it does not necessarily result in a competent worker. Therefore, it is essential to assess staff competence to ensure that the training provided is relevant and effective. Supervision and monitoring arrangements shall be in place to ensure that training has been effective, and the worker is competent at their job. The level of supervision and monitoring required is a management decision that shall be based on the risks associated with the job, the level of competence required, the experience of the individual and whether the worker works as part of a team or is a lone worker.

131

and be well known to, and easily understood by workers, visitors, and the general public as appropriate; and

(xvi) Disallow worker exposure to noise level greater than 85 dBA for duration of more than 8 hours per day without hearing protection. The use of hearing protection shall be enforced actively.

105. ASCL Heath and safety plan in response to COVID-19 will be an integral part of the environmental management plan (EMP).

(i) The H&S plan may be updated as and when new guidelines are issued by the governments, and international organizations such as WHO and ADB.

(ii) All the contractors will be advised to prepare site-specific plan compliant with government circulars, guidelines and public health advisories, elaborating the arrangements and measures for implementation of the H&S plan.

(iii) These site-specific plans should be shared with ADB after ACPL approval. In accordance with the government guidelines, the respective agreed measures are in place before start of activity at project sites and congregation of workers at the project site and camps. The implementation of the contractor’s approved site-specific plans is properly monitored by the project consultants and the PMU/PIUs.

176. Maintaining Core Labour Standard. The Contractor and ASCL are responsible for ensuring that international CLS19 –as reflected in national labor laws and regulations are adhered to. ASCL is ultimately responsible for monitoring compliance with national labor laws and regulations, provided that these national laws are consistent with CLS. ADB will carry out due diligence – during loan review missions – to ensure that executing and implementing agencies and contractors comply with applicable (national) core labor standards and labor laws. ASCL will ensure that bidding and contract documents include specific provisions requiring contractors to comply with all: (i) applicable labor laws and core labor standards on: (a) prohibition of child labor as defined in national legislation for construction and maintenance activities; (b) equal pay for equal work of equal value regardless of gender, ethnicity or caste; and (c) elimination of forced labor; and (ii) the requirement to disseminate information on sexually transmitted diseases including HIV/ AIDS to employees and local communities surrounding the project sites. These will be monitored as part of the project’s safeguards reporting requirements. 177. Community Health and Safety: Hazards posed to the public, specifically in high footfall density areas may include traffic accidents and vehicle collision with pedestrians. In most of the cases location of project sites are along the road ways, hence safety risk to community is to be considered with special emphasis to children, women and elderly. 178. Mitigation Measures:

(i) Provide barricades in all construction sites, especially near excavations to avoid entry of people specially children.

19 Core Labor Standards (CLSs) are a set of four internationally recognized basic rights and principles at work: (i) freedom of association and the right to collective bargaining; (ii) elimination of all forms of forced or compulsory labor; (iii) effective abolition of child labor; and (iv) elimination of discrimination in respect of employment and occupation.

132

(ii) Ensure that the traffic diversion plans are developed considering high footfall of women, children and elderly like schools, temples etc.

(iii) Ensure that no working equipment’s should be kept unattended. (iv) Plan material and waste routes to avoid times of peak-pedestrian activities

specially time of school in residential areas. (v) Maintain regularly the vehicles and use of manufacturer-approved parts to

minimize potentially serious accidents caused by equipment malfunction or premature failure

(vi) Provide road signs and flag persons to warn of dangerous conditions for all the work sites along the roads.

179. Work Camps. Operation of work camps can cause temporary air and noise pollution from machine operation, water pollution from storage and use of fuels, oils, solvents, and lubricants. Potential impacts are negative but short-term and reversible by mitigation measures. The construction contractor will be required to:

(i) Consult with ASCL/ PIU before locating project offices, sheds, and construction plants;

(ii) Minimize removal of vegetation and disallow cutting of trees; (iii) Provide water and sanitation facilities for employees; (iv) Prohibit employees from poaching wildlife and cutting of trees for firewood; (v) Train employees in the storage and handling of materials which can potentially

cause soil contamination; (vi) Recover used oil and lubricants and reuse or remove from the site; (vii) Manage solid waste according to the following preference hierarchy: reuse,

recycling and disposal to designated areas; (viii) Remove all wreckage, rubbish, or temporary structures which are no longer

required; and (ix) Request ASCL/ PIU to report in writing that the camp has been vacated and

restored to pre-project conditions before acceptance of work.

180. Social and Cultural Resources. For this project, excavation will occur at locations known not to have archaeological values, so it could be that there is a low risk of such impacts. Nevertheless, the construction contractor will be required to:

181. Mitigation Measures:

(i) Follow the protocol for chance finds (Appendix 11) in any excavation work; (i) Create awareness among the workers, supervisors and engineers about the

chance finds during excavation work; (ii) Stop work immediately to allow further investigation if any finds are suspected; (iii) Inform local Archaeological Department / Museum office if a find is suspected; take

any action they require ensuring its removal or protection in situ.

182. Sensitive Receptors: Since the work is being conducted in an urban sensitive area like schools, hospitals and religious center, the excavation of trenches laying activity will create nuisance and health hazard to children and people with ailments. There are various schools along the roads involved in the sub projects, such as Hindi HS school, Rashtriya Sanskrit school, Nirmala Shishu Vihal, Shrikrishna Mission school, Birjala Heigher secondary school etc. Hospitals named as State Government Ayurvedic Hospital, Devlok Hospital, IGM hospital. The measures

133

suggested under various heads in this section will minimize the impact in general in all areas; however, special attention is necessary at these locations. Following measures shall be implemented in 250 m around the sensitive locations (schools, hospitals, and religious centers) 183. Mitigation Measures:

(i) No material should be stocked in this area; material shall be brought to the site as and when required

(ii) Conduct work manually with small group of workers and less noise; minimize use of equipment and vehicles

(iii) No work should be conducted near the religious places during religious congregations

(iv) Material transport to the site should be arranged considering school timings of Hindi HS school, Rashtriya Sanskrit school, Nirmala Shishu Vihal, Shrikrishna Mission school, Birjala Heigher secondary school etc; material should be in place before school starts;

(v) Notify concerned schools, hospitals etc. 2 weeks prior to the work; conduct a 30-minute awareness program on nature of work, likely disturbances and risks and construction work, mitigation measures in place, entry restrictions and dos and don’ts

(vi) Implement all measures suggested elsewhere in this report – dust and noise control, public safety, traffic management, strictly at the sites.

(vii) In case of shifting of any religious or political statue, proper public consultation shall be done with documents and videography.

E. Guidelines for COVID -19

184. Construction sites operating during the Covid-19 pandemic need to ensure they are protecting their WORKFORCE and minimising the risk of spread of infection by strictly following the pre-approved EHS plan including COVID – 19 guidelines. The COVID -19 guidelines must updated strategies and recommendations for employers responding to COVID-19 including:

(i) Conducting daily health checks (ii) Conducting a hazard assessment of the workplace (iii) Encouraging employees to wear cloth face coverings in the workplace, if

appropriate (iv) Implementing policies and practices for social distancing in the workplace (v) Updated cleaning and disinfection guidance (vi) Updated strategies and recommendations that can be implemented now to

respond to COVID-19 (vii) A table outlining the engineering controls, administrative controls, and personal

protective equipment (PPE) that employers may use to help prevent the spread of COVID-19 in the workplace

(viii) Persons/Labourers showing COVID-19 symptoms or not providing self-attestation shall be directed to leave the work site and report to the fever clinic/quarantine centre immediately. Labour not to return to the work site until cleared by fever clinic/quarantine centre.

F. Workers Camp

134

185. Masks (homemade20 can be thought of) to be provided to all the persons/labourers for use at the camp site as well as at the worksite. Increase cleaning/disinfection visits to at least 2 times a day. Cleaning person(s) to be provided with disposable gloves, gown and face mask for each cycle of cleaning. G. UPDATES ON COVID-19

186. The Contractor shall be in touch with the Department of Health & Family Welfare and Labour Department to identify any potential worksite exposures relating to COVID-19, including:

(i) Strictly follow the guidelines issues by Ministry of health and OSHA (ii) Other workers, vendors, inspectors, or visitors to the worksite with close contact to

the individual (iii) Labour Camps / Work areas such as designated workstations or rooms /sheds (iv) Work tools and equipment (v) Common areas such as break rooms, tables and sanitary facilities (vi) PMU to ensure all government staff, Consultant and Contractor personal have

Aarogya Setu app, developed and recommended by GOI for tracking COVID-19 patients

H. Training

(i) PMU to ensure all workers get training on above requirements before start of any construction activity

(ii) During construction period frequent visual and verbal reminders to workers can improve compliance with hand hygiene practices and thus reduce rates of infection. Handwashing posters should also be displayed at work site and labour camps.

I. Emergency contact

(i) Provide emergency contact number at work site and labour camp for reporting COVID-19 symptoms.

J. Operation Phase Impacts

187. Screening out areas of no significant impact: Because a road up gradation project should operate without the need for major repair and maintenance, there are several environmental sectors which should be unaffected once the system begins to function. These are identified in Table 32 below, with an explanation of the reasoning in each case. These factors are thus screened out of the impact assessment and will not be mentioned further.

20 Advisory on use of Homemade Protective Cover for Face & Mouth by GOI.

135

Table 32: O&M Fields

Field Rationale

Climate No impact expected

Wildlife, forests, rare species, protected areas

The project is proposed in already established urban areas, no new area is infringed for the project.

Coastal resources Agartala is not located in a coastal area.

Industries The road network is for the urban part of the city, hence will not impact industries

188. Air Quality: Operation stage impacts will not be as severe as the construction stage impacts and they will be confined generally to a ribbon development close to edge of the pavement. After the completion of road project, smoothened new pavement and widened roads reduces fugitive dust emissions. Reduction in the vehicular emissions is due to more uniform speed and less frequent acceleration and deceleration of vehicles. The levels of SO2, NO2, CO and HC are likely to come down by the operating vehicles of new roads with extensive savings on consumption of fuel. However, there may be localized impact with increase in number of vehicles (traffic) running on the road, adulterated fuel supply and poor maintenance of vehicle, which spreads down depending on wind direction and wind speeds. 189. Mitigation measures:

(i) Vertical and median plantation along the road sides and medians respectively should help to control dust and fugitive emissions from reaching the receptors.

190. Ambient Noise: The noise will be reduced during operation stage as subproject road will be smoothened and widened as a part of road improvement. However, there will be noise generation due to honking of vehicles. 191. Mitigation measures

(i) Traffic management measures such as prohibition on use of horns and speed restrictions at noise sensitive areas like schools, civil courts and major hospitals reduce roadway noise levels.

(ii) Reduction in traffic congestion due to road widening correspondingly decreases traffic noise levels.

192. Surface water: Surface water contamination may result from storm water containing oil and grease, metals and other pollutants released by vehicles on the roadway. Storm water may also contain nutrients and herbicides used for management of vegetation in the right-of-way. The accidental spills of oils, fuels and other hazardous chemicals on the roads during operational phase will pollute nearby water courses of the area. 193. Mitigation measures

(i) During operation stage, regular cleaning of chocked / blocked or damaged drainage provision are necessary to avoid operational impact.

(ii) Monitoring of water quality to comply with Water (Prevention and Control of Pollution) Act will have better control over the quality maintenance.

194. Hydrology and Drainage: Hydrology of the project area is least impacted during operation stage, if all design criterion is taken into consideration during construction.

136

195. Mitigation measures

(i) Regular maintenance of drains by removing the silt and dirt before the start of monsoon will prevent choking of drains.

196. Terrestrial ecology: Impacts to terrestrial ecology during project operation are either minimal or positive. Trees will be planted along the road such that it does not affect the visibility and improve micro-climate and sequester greenhouse gases. 197. Mitigation measures

(i) All efforts shall be made for survival of planted trees. (ii) Selection of big tree species having lateral growth should be avoided to ensure

vertical clearance on the subproject road to avoid any obstruction to the visibility for the operating vehicles. Small avenue trees shall be preferred over big trees. Fruit bearing avenue trees shall be avoided.

(iii) It is necessary to comply with Hazardous Waste (Handling and Management) Rules, 2016 during road construction projects to protect animals by consuming contaminated water. Accidental chemical spills shall be handled by emergency spill procedure such as stopping the flow; removing ignition source; initiating emergency response; cleanup and safe disposal will be followed.

198. Occupational Health and Safety: Incidents during maintenance in utility ducts. Accidental chemical spill or indiscriminate disposal of bituminous materials in the project area may impact the terrestrial ecology and enter surrounding water bodies proving detrimental to local fauna. 199. Mitigation measures

(i) Chambers and Openable covers are provided for every 15 m for ease of maintenance.

(ii) Sufficient width is considered for man movement in the duct for free movement. (iii) Lock out Tag out (LOTO) system for all electrical equipment and the system will

be shut down before maintenance to avoid any incidences. (iv) Commuters and road using community will be educated on the road safety issues

to reduce the accidents involving traffic. (v) Accident Safety and Hazardous Chemical Spill Management Plan shall be

prepared by the contractor and submitted to Environmental Engineer, PIU. The plan should also have details of detours in case of emergency.

200. Community health and safety. The more significant health and safety issues from road project are pedestrian safety, traffic safety, and emergency preparedness. 201. Mitigation Measures

(i) The maintenance of signs, signals, markings, speed limits, warnings of sharp turns shall be maintained. The awareness among the communities on emergency preparedness in addressing emergency situations like vehicular accidents, pedestrian accident, or release of oil and chemical spill.

137

202. Anticipated indirect, induced, cumulative impacts: The project is also assessed for indirect, induced and cumulative impacts. Indirect and induced impacts are identified as impacts of the project caused at the operational stage like, rise in vehicular traffic leading to rise emission levels, the improved road conditions may lead to speeding of vehicles and increase the probability of accidents. The design parameters have considered these aspects and necessary mitigation measures like traffic signals, CCTV camera installations, well lit streets, rumble strips to control speed etc., have been adequately incorporated.

203. Cumulative impacts of proposed road project include the degradation of surface water quality due to land clearance and construction activities induced due to the proposed project, urban population growth near the proposed improved roads, increased forest/ tree cutting due to clearance and consumption of wood and timber products.

204. Climate change: It is of strategic importance that proposed development should be designed keeping in mind the future challenges of climate change. The proposed road project has considered the past rainfall data for quantification of runoff and the drain design features have incorporated the same. There are storm water pumping stations to handle flooding of roads in Agartala at few select roads which are vulnerable to flood risk. A detailed adequacy study of the existing infrastructure show that the current pumping capacity and numbers are sufficient to meet the current and forecasted flood risks. Further, augmentation of the storm water pumping stations for handling the flash flood events strengthens the climate resilient design consideration.

205. Greenhouse gas emissions: Several steps involved in road construction, contributes to the production and release of greenhouse gas emissions, the activities involved are site clearing and construction activities, raw material sourcing, material storage, preparation of the sub-grade, production of construction materials (i.e. granular sub-base, base course, surfacing), site delivery, construction works and methodology, supervision, maintenance activities, etc.

206. Mitigation measures:

(i) The excavated earth generated from site clearance activity will be reused in site for backfilling reducing the sourcing of fresh material.

(ii) The maximum raw materials required for the projects are sourced locally to reduce the emissions from transportation.

(iii) The raw materials are proposed to be stored in decentralized open areas identified along HGB Road, Barjala Road, Jail Road and GB Road to minimize the distance of transport raw material and reducing the greenhouse gases.

(iv) The pavement materials and other construction materials are designed to bear the load which is going to cater on the pavement throughout the design life of 15 years.

(v) The construction drains and utility ducts in the proposed project are designed considering the future requirements so that frequent design changes and demolition are avoided.

207. Unanticipated impacts: Some of the cumulative impacts and Unanticipated impacts during the construction phase and operation phase shall be mitigated with suitable mitigation measures which is to be implemented by the PMU and same will be reported and updated in IEE report.

VII. PUBLIC CONSULTATION, PARTICIPATION AND INFORMATION DISCLOSURE

A. Overview

138

208. The active participation of stakeholders including local community, NGOs/CBOs, and the media in all stages of project preparation and implementation is essential for successful implementation as well as operation of the project. It will ensure that the subprojects are designed, constructed, and operated with utmost consideration to local needs, ensures community acceptance, and will bring maximum benefits to the people. Public consultation and information disclosure are a must as per the ADB SPS 2009. 209. A three-tier consultation process has been adopted: focus group discussions, primary household sample surveys and a town-level public consultation workshop. Most of the main stakeholders have already been identified and consulted during preparation of this IEE, and any others that are identified during project implementation will be brought into the process in the future. Primary stakeholders of the subproject are: residents, shopkeepers and businesspeople who live and work alongside the roads in which network improvements will be provided, and government and utility agencies responsible for provision of services, Agartala municipal corporation, Public Health Engineering Department and Tripura State Pollution Control Board. Secondary Stakeholder are: NGOs and CBOs working in the area, community representatives, beneficiary community in general, government agencies, the executing and implementing agencies, Government of India and the ADB.

The sample traffic management plan is attached in this report for reference.

222. Consultation with Auto-drivers: The consultation was done with Auto rickshaw drivers in Autostand at Akhaura Road and they were informed that the location of the stand will be disturbed temporarily during the construction stage. The auto-drivers were also informed about the benefits of road upgradation project. The drivers showed their approval for the project as the project will improve the traffic situation in the city and at the same time the improvement in the utilities like covered drains etc., will improve overall quality of life of Agartala residents. E. Future Consultation and Disclosure

223. The public consultation and disclosure program will remain a continuous process throughout the subproject implementation and shall include the following:

1. Consultation during Construction

224. Prior to start of construction, AMC and PIU with the assistance of PMC will conduct information dissemination sessions at major intersections and solicit the help of the local community leaders/prominent citizens to encourage the participation of the people to discuss various environmental issues. At each ward/neighborhood level, focus group meetings will be conducted to discuss and plan construction work with local communities to reduce disturbance and other impacts, and provide a mechanism through which stakeholders can participate in project monitoring and evaluation.

142

225. A constant communication will be established with the affected communities to redress the environmental issues likely to surface during construction and operational phases and also regarding the grievance redress mechanism. AMC/PIU with the help of PMC will organize public meetings and will appraise the communities about the progress on the implementation of EMP. Meeting will also be organized at the potential hotspots/sensitive locations before and during the construction. 226. Public meetings with affected communities (if any) to discuss and plan work programs and allow issues to be raised and addressed once construction has started. 227. Smaller-scale meetings to discuss and plan construction work with local communities to reduce disturbance and other impacts and provide a mechanism through which stakeholders can participate in subproject monitoring and evaluation. 228. During construction, increased traffic, excess generation of dust and noise due to construction activities may cause some inconveniences to the local population. Mitigation measures are already considered in the IEE to keep this at a minimum. Community consultations have already been carried out. During construction, multiple consultations at various levels will be carried out ensuring clear communication to the affected persons about the likely transient impact during construction and continued impact, if any, during the operation stage.

2. Information Disclosure 229. Executive summary of the IEE will be translated in the local language and made available at the offices of AMC, PMU and PIU.

VIII. GRIEVANCE REDRESS MECHANISM

A. Common Grievance Redress Mechanism (GRM)

235. A common grievance redress mechanism (GRM) will be put in place to receive, evaluate, and facilitate the resolution of social, environmental or any other project related grievances. The GRM will aim to provide a time-bound and transparent mechanism to voice and resolve social and environmental concerns linked to the project. The GRM described below has been developed in consultation with stakeholders. Public awareness campaign will be conducted to ensure that awareness on the project and its grievance redress procedures is generated. The campaign will ensure that the poor, vulnerable and others are made aware of.

236. The GRM provides an accessible, inclusive, gender-sensitive and culturally appropriate platform for receiving and facilitating resolution of affected persons' grievances related to the project. The multi-tier GRM for the project is outlined below, each tier having time-bound schedules and with responsible persons identified to address grievances and seek appropriate persons’ advice at each stage, as required. ULB-wide public awareness campaigns will ensure that awareness on grievance redress procedures is generated through the campaign. The Environmental and Social Safeguard Officer of PMU will have the overall responsibility for timely grievance redress on environmental and social safeguards issues.

237. Who can complain: A complaint may be registered by stakeholders who may be, “directly, indirectly, materially, and adversely” affected by the project. Any other representative can register

144

a complaint on behalf of the affected person/s or any stakeholder by, provided that he or she identifies the affected person/s and includes evidence of the authority to act on their behalf. 238. What the Grievance/Complain should contain: Any concerns pertaining to safeguard compliance - environment, involuntary resettlement, and indigenous people, design related issues, compensation, service delivery or any other issues or concerns related to the project. The complaint must contain name, date, address/contact details of the complainant, location of the problem area, along with the problem. Sample grievance registration form is attached in Appendix12.

239. Where & How to file a Complaint: The contractor’s site office will be the primary point for receiving and lodging any complaint. Apart from that, Grievances/ suggestions from affected persons can be dropped into suggestion boxes or conveyed through phone or e-mails. Affected Persons or any complainant will also be able to register grievances on social, environmental or other related issues, personally to the Central Complaint Cell located at ASCL office. Sample grievance redressal form is attached in Appendix 10. The Grievance Officer and designated official will be able to correctly interpret/record verbal grievances of non-literate persons and those received over telephone. The concerned Executive Engineers/ Asst. Engineer/ contractor’s site engineer, Environment Health & Safety (HSE) Officer of Contractor will monitor these books and if possible take necessary actions to redress minor complaints with intimation to the complainant as well as to the Central Compliant Cell established at PIU level. The time period to resolve any grievances at different level of GRC has been discussed below.

240. PMU will maintain a Central Complaint Cell at ASCL office located in Agartala Municipal Corporation headed by a designated Grievance Officer/Administrative/ Executive Officer under CEO, ASCL. The Complaint Cell will also serve as Public Information Centre, where, apart from grievance registration, information on the Project, subprojects, social and environmental safeguards, etc. can be provided.

241. Documentation: Documentation of the complaints is important and must contain name of the complainant, date of receipt of the complaint, address/contact details of the person, location of the problem area, and how the problem was resolved. PMU with the support of PIU will have the overall responsibility for timely grievance redress, and for registration of grievances, related disclosure, and communication with the aggrieved party. All the documents made available to the public at the community level (at ward offices) and will include information on the contact number, address and contact person for registering grievances, and will be disseminated throughout the project area by the PIU.

242. Grievance/Problem Redress through Participatory Process: Efforts must be made by the PIU with the support of safeguard officers to resolve problems and conflicts amicably through participatory process with the community and the ULBs. In case of grievances that are immediate and urgent in the perception of the complainant, the Contractor and supervision personnel from the PIU will provide the most easily accessible or first level of contact for the quick resolution of grievances. Contact phone numbers and names of the concerned staff and contractors will be posted at all construction sites at visible locations.

243. Grievance Redressal Committee: In pursuance of Asian Development Bank (ADB) Guideline, an independent Grievance Redressal Committee (GRC) has to be established under Agartala Smart City Limited (ASCL) to address the grievance of persons affected due to

145

implementation of sub- projects under ADB assisted projects. The composition of the GRC is provided in Table 33 below:

244. Process and Timeframe:

(i) 1st level grievance: In case of grievances that are immediate and urgent in the perception of the complainant, concerned officer of PIU will direct the contractor to and ensure that it is resolved. If the grievance is not under the contractor scope, but under the project, PMC (field office) will resolve this issue. All the grievances should be resolved within 7 days of receipt of a complaint/ grievance.

(ii) 2nd level grievance: All grievances that cannot be redressed at first level within 7 days will be brought to the notice of E&S nodal officer of ASCL to place the issue to CEO ASCL. The Grievance Officer may consult/seek the assistance of the Environment & Social officer and Public Engagement Officer of the PMU and E&S Officer of PMC to resolve the complicated issues. The Central GRC will review the grievance and act appropriately to resolve it within 7 days of receipt at this level.

(iii) 3rd level grievance: All the grievances that are not addressed at 2nd level by PIU within in 15 days of receipt will be brought to the notice of the Apex Grievance Redressal Committee (GRC). The Apex GRC will meet twice a month and determine the merit of each grievances brought to the committee. The GRC will resolve the grievance within 1 month of receiving the complaint. The Social Safeguard Officer will communicate all decisions taken by the GRC to the complainant by the

245. The process of the grievance redressal mechanism (GRM) is given in Figure below.

Figure 30: Grievance Redressal Mechanism

246. In case of any inter-departmental or inter-jurisdictional coordination required for resolution of specific grievances, the PIU will refer the matter directly to the CEO ASCL for state-level or inter-departmental coordination and resolution. The project GRM notwithstanding, an aggrieved person shall have access to the country's legal system at any stage and accessing the country's legal system can run parallel to accessing the GRM and is not dependent on the negative outcome of the GRM. 247. Periodic community meetings with affected communities to understand their concerns and help them through the process of grievance redress (including translation from local dialect/language, recording and registering grievances of non-literate affected persons and explaining the process of grievance redress) will be conducted if required. The above Grievance Redress Process will be discussed with the different stakeholders during stakeholder consultation meetings. These meetings will be held with affected persons and community members (beneficiaries) and the concerned Municipal Ward Councilors where civil works are proposed. The process and timelines for grievance redress and contact details of the persons responsible for grievance redress will be shared in the stakeholder meetings. Action taken in respect of all complaints will be communicated to the complainant by letter, over phone or e-mail or WhatsApp as the case may be.

248. Consultation Arrangements for GRM - This will include group meetings and discussions with affected persons, to be announced in advance and conducted at the time of day agreed on with affected persons and conducted to address general/common grievances; and if required with the Environment/Social Specialist of PMU/ PMC for one-to-one consultations. Non-literate affected persons/ vulnerable affected persons will be assisted to understand the grievance redress process, At the site office the Social Safeguard Officer of contractor and at PIU level, the Grievance officer or any other official appointed at receiving section will assist the Non-literate APs to register complaints and with follow-up actions at different stages in the process. 249. Record keeping. Records of all grievances received, including contact details of complainant, date the complaint was received, nature of grievance, agreed actions and measures, the date these were affected, and final outcome will be kept by PIU. The number of grievances recorded and resolved and the outcomes will be displayed/disclosed in the PIU office, ULB office and on the web, as well as reported in the semi-annual social and environmental monitoring reports to be submitted to ADB.

250. Information dissemination methods of the GRM: Grievances received, and responses provided will be documented and reported back to the affected persons. The number of grievances recorded and resolved and the outcomes will be displayed/disclosed in the Central Complaint Cell at ASCL and web. The phone number where grievances are to be recorded will be prominently displayed at the construction sites.

251. Periodic review and documentation of lessons learned. The PMU, and PIUs, supported by the PMC specialist will periodically review the functioning of the GRM and record information on the effectiveness of the mechanism, especially on the PIU’s ability to prevent and address grievances.

252. Costs: All costs involved in resolving the complaints (meetings, consultations, communication and reporting/information dissemination) will be borne by the PMU. 253. ADB Accountability Mechanism: If the established GRM is not in a position to resolve the issue, the affected person also can use the ADB Accountability Mechanism through directly contacting (in writing) the Complaint Receiving Officer (CRO) at ADB headquarters or the ADB India Resident Mission (INRM). Before submitting a complaint to the Accountability Mechanism, it is recommended that affected people make a good faith effort to resolve their problems by working with the concerned ADB operations department (in this case, the resident mission). Only after doing that, and if they are still dissatisfied, they could approach the Accountability Mechanism. The ADB Accountability Mechanism information will be included in the project-relevant information to be distributed to the affected communities, as part of the project GRM.

IX. ENVIRONMENTAL MANAGEMENT PLAN

A. Environmental Management Plan

254. An Environmental Management Plan (EMP) has been developed to provide mitigation measures to reduce all negative impacts to acceptable level and monitoring the same. This is presented in the following tables, which show the potential environmental impacts, designed mitigation measures and responsible agencies for implementation and monitoring. 255. The purpose of the environmental management plan (EMP) is to ensure that the activities are undertaken in a responsible, non-detrimental manner with the objectives of: (i) providing a

148

proactive, feasible, and practical working tool to enable the measurement and monitoring of environmental performance on-site; (ii) guiding and controlling the implementation of findings and recommendations of the environmental assessment conducted for the project; (iii) detailing specific actions deemed necessary to assist in mitigating the environmental impact of the project; and (iv) ensuring that safety recommendations are complied with. 256. A copy of the EMP must always be kept on work sites. The EMP will be made binding on all contractors operating on the site and will be included in the contractual clauses. Non-compliance with, or any deviation from, the conditions set out in this document constitutes a failure in compliance.

257. For civil works, the contractor will be required to (i) establish an operational system for managing environmental impacts (ii) carry out all the monitoring and mitigation measures set forth in the EMP; and (iii) implement any corrective or preventative actions set out in safeguards monitoring reports that the employer will prepare from time to time to monitor implementation of this IEE and EMP. The contractor shall allocate a budget for compliance with these EMP measures, requirements and actions.

258. In case of any change in design the contractor will be required to submit to PIU, for review and approval, an updated site environmental plan (SEP) including (i) designed sites/locations for construction work camps, storage areas, hauling roads, lay down areas, disposal areas for solid and hazardous wastes; (ii) specific mitigation measures following the approved EMP; (iii) monitoring program as per SEP; and (iv) budget for SEP implementation. No works can commence prior to approval of SEP.

259. Site Specific Environmental Management Plan is prepared for the Upgradation of Major Roads to ensure compliance with the ADB’s environmental safeguard requirements and all applicable laws, regulations and standards for environmental protection in India. The EMP ensures that the proposed project activities are undertaken in a responsible, non-detrimental manner with the objectives of:

(i) providing a proactive, feasible, and practical working tool to enable the measurement and monitoring of environmental performance on-site;

(ii) guiding and controlling the implementation of findings and recommendations of the environmental assessment conducted for the project;

(iii) detailing specific actions deemed necessary to assist in mitigating the environmental impact of the project; and

(iv) ensuring that safety recommendations are complied with.

260. These site specific EMPs will be included in the tender and contract documents. The provisions set out in the EMPs will be implemented by the Contractor and monitored by the

150

Engineer under supervision of PIU Environmental Specialist. Monitoring shall be implemented through the monitoring site visits of environmental specialists of all Project levels. The site visits shall be carried out in accordance with the formal monitoring schedule: Contractor- daily, Engineer -weekly and PIU - monthly. The costs foreseen for the implementation of all the measures prescribed in the EMP are included in the Bill of Quantities. 261. Environmental Risk Assessment: The environmental aspects and impacts are identified with the aim to control/ prevent pollution to the environmental and to ensure ADB environmental safeguard requirements and all other legal requirements are being complied with. The assessment shall consider normal, abnormal and foreseeable emergency situations and consider where applicable, the aspects associated with the various project. 262.

D. Training Needs

288. Executing and implementing agencies need to have a sustained capacity to manage and monitor environmental safeguards. Although specialist consultants support will be available to PMU and PIUs, it is necessary to mainstream safeguards in day-to-day working. Therefore, PMU and PIUs require capacity building measures for (i) a better understanding of the project-related environmental issues; and (ii) to strengthen their role in preparation of IEE, implementation of mitigation measures, and subsequent monitoring. Trainings and awareness workshops are included in the project with the primary focus of enabling the PMU and PIU staff to understand impact assessments and carry out environmental monitoring and implement EMPs. After participating in such activities, the participants will be able to review environmental assessments, conduct monitoring of EMPs, understand government and ADB requirements for environmental assessment, management, and monitoring (short- and long-term), and incorporate environmental features into future project designs, specifications, and tender documents and carry out necessary checks and balances during project implementation.

255

289. Typical modules would be as follows: (i) sensitization; (ii) introduction to environment and environmental considerations in water supply and wastewater projects; (iii) review of IEEs and integration into the project detailed design; (iv) improved coordination within nodal departments; and (v) monitoring and reporting system. Specific modules customized for the available skill set will be devised after assessing the capabilities of the target participants and the requirements of the project. The contractors will be required to conduct environmental awareness and orientation of workers prior to deployment to work sites.

290. The following Table 49 presents the outline of capacity building program to ensure EMP implementation. The estimated cost is Rs. 3,35,000 (excluding trainings of contractors which will be part of EMP implementation cost during construction) to be covered by the project’s capacity building program. The detailed cost and specific modules will be customized for the available skill set after assessing the capabilities of the target participants and the requirements of the project.

E. Monitoring and Reporting

291. Prior to commencement of the work, the contractor will submit a compliance report to ASCL/ PIU ensuring that all identified pre-construction environmental impact mitigation measures as detailed in the EMP will be undertaken. ASCL with the assistance of the consultant environment specialist will review the report and thereafter ASCL will allow commencement of works. During construction, results from internal monitoring by the contractor will be reflected in their weekly EMP implementation reports to the Construction Supervision Specialist. These weekly reports will be retained in construction supervision office for reference. Construction Supervision Specialist will review and advise contractors for corrective actions if necessary. Sample site inspection checklist is attached in Appendix 12, semi-annual monitoring report (Appendix 13) summarizing compliance and corrective measures taken will be prepared by Construction Supervision Specialist to be reviewed and endorsed by Municipal Corporation to Agartala Smart City Ltd. SEMR will also include monitoring details relating to the implementation of site specific OHS plan and compliance with the COVID19 plan. Based on monthly reports and measurements, PMU will draft, review, and submit to ADB, 6-monthly (twice a year) EMP implementation progress report (Appendix 13). Once concurrence from the ADB is received the report will be disclosed in the Project website. ADB will review project performance against the Agartala Smart City Ltd commitments as agreed in the legal documents. The extent of ADB's monitoring and supervision activities will be commensurate with the project's risks and impacts. Monitoring and supervising

257

of social and environmental safeguards will be integrated into the project performance management system.

292. Monitoring Methods: All environmental monitoring and relevant operational data will be stored in a relational database and linked MIS system. This will enable efficient retrieval and storage and interpretation of the data. Regular data extracts and interpretive reports will be sent to the regulator.

293. Air Quality Monitoring: The ambient concentrations of SPM, SO2, NOx, CO and HC in the ambient air will be monitored at regular intervals. Any abnormal rise will be investigated to identify the causes, and appropriate action will be initiated. Green belt shall be developed for minimizing dust propagation. The ambient air quality data should be transferred and processed in a centralized computer facility equipped with required software. Trend and statistical analysis should be done. 294. Noise Levels: Ambient noise levels near habitations shall also be monitored once in six months. Audiometric tests should be conducted periodically for the employees working close to the high noise sources.

295. Monitoring of Surface Water: Methods prescribed in “Standard Methods for Examination of water and Wastewater” prepared and published jointly by American Public Health Association (APHA), American Water Works Association (AWWA) and Water Pollution Control Federation (WPCF); Manual on water and wastewater Analysis published by NEERI, Nagpur are recommended.

296. Monitoring Ground Water: The groundwater samples shall be taken from representative locations periodically and analyzed for necessary corrective actions, if any

297. Data Analysis: The monitored data will be analyzed and compared with the baseline and the regulatory standards specified by different government agencies. The standards against which the different environment components will be compared are as per Table 50.

5. Soil Quality --

F. EMP Implementation Cost

298. Most of the mitigation measures require the contractors to adopt good site practice, which should be part of their normal procedures already, so there are unlikely to be major costs associated with compliance. Regardless of this, any costs of mitigation by the construction contractors or consultants are included in the budgets for the civil works and do not need to be estimated separately here. Cost for the capacity building program is included as part of the project. The EMP cost includes the cost for providing water supply, sanitation facilities etc., for the workers. In addition to this, hard barricades need to be provided at the work sites to prevent any entry of the public or animals into the worksite and to prevent any possible accidents.

X. CONCLUSION AND RECOMMENDATIONS

299. The process described in this document has assessed the environmental impacts of all elements under the Subproject. Potential negative impacts were identified in relation to design, pre-construction, construction and operation & maintenance of the proposed infrastructure. Mitigation measures have been developed in generic way to reduce all negative impacts to acceptable levels. The project sites are existing roads hence no land acquisition is required for the project.

300. During the construction phase, impacts mainly arise from the air and noise pollution and from traffic disruption by the construction work. These are common impacts of construction in urban areas, and there are well developed methods for their mitigation. Since the project involves redevelopment of the existing roads, this has potential to create disturbance. To minimize this, the contractor should develop a work method in consultation with ASCL, ULB and Consultants prior to start of work, and should conduct the work strictly in line with the work methods.

301. Handling of traffic is a most significant aspect of the proposed project during the construction phase. A detailed traffic management plan including diversion plans needs to be developed during the execution of the project. There were limited opportunities to provide enhancements, but certain measures were included. For example, it is proposed that the project will employ in the workforce people who live in the vicinity of or in Agartala city to provide them with a short-term economic gain and ensure that people employed in the longer term to maintain and operate the new facilities are residents of nearby communities. The citizens of the Agartala City will be the major beneficiaries of this project. In addition to improved environmental conditions, the subproject will improve the over-all health condition of the town.

302. Mitigation will be assured by a program of environmental monitoring conducted during construction and operation to ensure that all measures are implemented, and to determine whether the environment is protected as intended. This will include observations on- and off- site, document checks and interviews with workers and beneficiaries and any requirements for remedial action will be reported to the ASCL. Finally, stakeholders were involved in developing the IEE through one-on-one discussions and on-site meetings, after which views expressed were incorporated into the IEE and the planning and development of the project. Involvement of NGO’s and City level consultation involving all stakeholders could not be held and the same is required to be conducted at various stages of project like pre-construction and construction.

303. The IEE will be made available at public locations in the city and will be disclosed to a wider audience via the ADB website. The consultation process will be continued and expanded during project implementation to ensure that stakeholders are fully engaged in the project and have the opportunity to participate in its development and implementation.

304. The proposed project of up gradation of road, footpaths and junction in Agartala city is unlikely to cause significant adverse impacts. The potential adverse impacts that are associated with design, preconstruction, construction and operation can be mitigated to standard levels without difficulty through proper engineering design and the incorporation or application of recommended mitigation measures and procedures. Based on the findings of the IEE, the classification of the Project as Category “B” is confirmed, and no further special study or detailed EIA needs to be undertaken to comply with ADB SPS (2009) or GoI EIA Notification (2006).

Appendix 5: Spoils Management Plan

A. Spoil Management Plan 1. Purpose and Application: Spoils Management plan (SMP) is to describe how ASCL/ PIU will manage the spoil generated and reuse related to design and construction works. This is an integral part of EMP. The objective of SMP is to reuse of spoil from works in accordance with the spoil management hierarchy outlined in this document. 2. Objectives of SMP: The objectives of SMP are:

• To minimize spoil generation where possible • Maximize beneficial reuse of spoil from construction works in accordance with spoil

management hierarchy • Mange onsite spoil handling to minimize environmental impacts on resident and other

receivers • Minimize any further site contamination of land, water, soil • Manage the transportation of spoil with consideration of traffic impacts and transport

related emissions

3. Structure of SMP: Section 1: Introduction of SMP Section 2: Legal and other requirements Section 3: Roles and responsibilities Section 4: Identification and assessment of spoil aspects and impacts Section 5: Spoil volumes, characteristics and minimization Section 6: Spoil reuses opportunities, identification and assessment Section 7: On site spoil management approach Section 8: Spoil transportation methodology Section 9: Monitoring, Reporting, Review, and Improvements 4. Aspects and Potential Impacts: The key aspects of potential impacts in relation to SMP are listed in Table below:

Table: Key Aspect of Potential Impacts Aspect Potential Impact

Air Quality Potential for high winds generating airborne dust from the stock piles

Sedimentation Potential for sediment laden site runoff from spoil stockpiles and potential for spillage of spoil from truck on roads

Surface and Groundwater

Contamination of water (surface and ground water)

Noise Associated with spoil handling and haulage and storage Traffic Impacts associated with spoil haulage Land Use Potential for spoil to be transported to a receivable site that

doesn’t have permission for storage/disposal Design specifications

Limitations on opportunities to minimize spoil generation

Sustainability Limited sites for storage, reuse opportunities B. Spoil volumes, Characteristics and Minimization 5. Spoil Volume Calculations. Estimate the volumes of spoils produced from each of the construction site

530 Appendix 5

6. Characterization of Spoil. Based on the type of spoil; characterization is done (sand stone, mix materials, reusable materials. 7. Adopt Spoil Reduce, Reuse Opportunities. An overview of the assessment methodology to be used is mentioned below.

• Consideration of likely spoil characteristics • Identification of possible reuse sites • Screening of possible reuse opportunities

8. Identification of Possible Safe Disposal Sites for Spoil. Those spoils which can’t be reuse shall be properly disposed in designated areas (DC Nagar Lunga in Agartala). Such disposal areas should be safe from environmental aspects and there should be any legal and resettlement related issues. Such areas need to be identified and prior cliental approval should be obtained to use it as spoil disposal area. The local administration must be consulted and if required permission should be obtained from them. C. Storage and Stock Piling 9. Stockpiling. Spoils shall be stockpiled at locations at least 300 m away from water courses and covered. 10. Transportation and Haulage Route. Based on the above, the contractor will prepare a transport and route plan, and submit it to the PIU for their review and approval. D. Summary of Key Issues and Remedial Actions 11. Summary of follow up time-bound actions to be taken within a set timeframe.

Appendix 8: Sample Traffic Management Plan (TMP)

A. Principles 1. One of the prime objectives of this TMP is to ensure the safety of all the road users along the work zone, and to address the following issues:

(i) the safety of pedestrians, bicyclists, and motorists travelling through the construction zone;

(ii) protection of work crews from hazards associated with moving traffic; (iii) mitigation of the adverse impact on road capacity and delays to the road users; (iv) maintenance of access to adjoining properties (v) Avoid hazards in addressing issues that may delay the project.

B. Operating Policies for TMP 2. The following principles will help promote safe and efficient movement for all road users (motorists, bicyclists, and pedestrians, including persons with disabilities) through and around work zones while reasonably protecting workers and equipment.

(i) Make traffic safety and temporary traffic control an integral and high-priority element of every project from planning through design, construction, and maintenance.

(ii) Inhibit traffic movement as little as possible. (iii) Provide clear and positive guidance to drivers, bicyclists, and pedestrians as they

approach and travel through the temporary traffic control zone. (iv) Inspect traffic control elements routinely, both day and night, and make

modifications when necessary. (v) Pay increased attention to roadside safety in the vicinity of temporary traffic control

zones. (vi) Train all persons that select, place, and maintain temporary traffic control devices. (vii) Keep the public well informed. (viii) Make appropriate accommodation for abutting property owners, residents,

businesses, emergency services, railroads, commercial vehicles, and transit operations.

C. Analyze the impact due to street closure, if required 3. Apart from the capacity analysis, a final decision to close a particular street and divert the traffic should involve the following steps:

(i) approval from the PIU, local administration to use the local streets as detours; (ii) consultation with businesses, community members, traffic police, PWD, etc,

regarding the mitigation measures necessary at the detours where the road is diverted during the construction;

(iii) determining of the maximum number of days allowed for road closure, and incorporation of such provisions into the contract documents;

(iv) determining if additional traffic control or temporary improvements are needed along the detour route;

(v) considering how access will be provided to the worksite; (vi) contacting emergency service, school officials, and transit authorities to determine

if there are impacts to their operations; and (vii) developing a notification program to the public so that the closure is not a surprise.

As part of this program, the public should be advised of alternate routes that commuters can take or will have to take as result of the traffic diversion.

Appendix 8 543

4. If full road-closure of certain streets within the area is not feasible due to inadequate capacity of the Detour Street or public opposition, the full closure can be restricted to weekends with the construction commencing on Saturday night and ending on Monday morning prior to the morning peak period. Figure: Policy Steps for the TMP

D. Public awareness and notifications 5. As per discussions in the previous sections, there will be travel delays during the constructions, as is the case with most construction projects, albeit on a reduced scale if utilities and traffic management are properly coordinated. There are additional grounds for travel delays in the area, as most of the streets lack sufficient capacity to accommodate additional traffic from diverted traffic as a result of street closures to accommodate the works. 6. The awareness campaign and the prior notification for the public will be a continuous activity which the project will carry out to compensate for the above delays and minimize public claims as result of these problems. These activities will take place sufficiently in advance of the time when the roadblocks or traffic diversions take place at the particular streets. The reason for this is to allow sufficient time for the public and residents to understand the changes to their travel plans. The project will notify the public about the roadblocks and traffic diversion through public notices, ward level meetings and city level meeting with the elected representatives. 7. The ASCL/ PIU will also conduct an awareness campaign to educate the public about the following issues:

(i) Traffic control devices in place at the work zones (signs, traffic cones, barriers, etc.);

(ii) Defensive driving behaviour along the work zones; and (iii) Reduced speeds enforced at the work zones and traffic diversions.

Review• Review construction schedule and methods

• Install traffic control devices (traffic cones, sgns, lightings, etc)

Awareness • Conduct campaigns, publicity, and notify public about street closure

Public

Redress

• Develop a mechanism to address public grievances regarding disruptons (traffic, utilities, and diversions)

544 Appendix 8

8. It may be necessary to conduct the awareness programs/campaigns on road safety during construction. 9. The campaign will cater to all types of target groups i.e. children, adults, and drivers. Therefore, these campaigns will be conducted in schools and community centers. In addition, the project will publish a brochure for public information. These brochures will be widely circulated around the area and will also be available at the PIU, and the contractor's site office. The text of the brochure should be concise to be effective, with a lot of graphics. It will serve the following purpose:

(i) explain why the brochure was prepared, along with a brief description of the project;

(ii) advise the public to expect the unexpected; (iii) educate the public about the various traffic control devices and safety measures

adopted at the work zones; (iv) educate the public about the safe road user behaviour to emulate at the work

zones; (v) tell the public how to stay informed or where to inquire about road safety issues at

the work zones (name, telephone, mobile number of the contact person; and (vi) indicate the office hours of relevant offices.

E. Vehicle Maintenance and Safety 10. A vehicle maintenance and safety program shall be implemented by the construction contractor. The contractor should ensure that all the vehicles are in proper running condition and it comply with roadworthy and meet certification standards of Tripura Govt./ GoI. All vehicles to be used shall be in perfect condition meeting pollution standards of Tripura Govt./ GoI. The vehicle operator requires a pre-state of shift checklist. Additional safety precautions will include the requirement for:

• Driver will follow the special code of conduct and road safety rules of Government of India • Drivers to ensure that all loads are covered and secured drivers to ensure operation

equipment can’t leak materials hauled • Vehicles will be cleaned and maintained in designed places.

F. Install traffic control devices at the work zones and traffic diversion routes 10. The purpose of installing traffic control devices at the work zones is to delineate these areas to warn, inform, and direct the road users about a hazard ahead, and to protect them as well as the workers. As proper delineation is a key to achieve the above objective, it is important to install good traffic signs at the work zones. The following traffic control devices are used in work zones:

• Signs • Pavement Markings • Channelizing Devices • Arrow Panels • Warning Lights

11. Procedures for installing traffic control devices at any work zone vary, depending on road configuration, location of the work, construction activity, duration, traffic speed and volume, and pedestrian traffic. Work will take place along major roads, and the minor internal roads. As such, the traffic volume and road geometry vary. The main roads carry considerable traffic; internal roads in the new city areas are wide but in old city roads very narrow and carry considerable traffic. However, regardless of where the construction takes place, all the work zones should be cordoned off, and traffic shifted away at least with traffic cones, barricades, and temporary signs (temporary “STOP” and “GO”).

Appendix 8 545

12. The work zone should take into consideration the space required for a buffer zone between the workers and the traffic (lateral and longitudinal) and the transition space required for delineation, as applicable. For the works, a 30 cm clearance between the traffic and the temporary STOP and GO signs should be provided. In addition, at least 60 cm is necessary to install the temporary traffic signs and cones. 13. Traffic police should regulate traffic away from the work zone and enforce the traffic diversion result from full street closure in certain areas during construction. Flaggers/ personnel should be equipped with reflective jackets at all times and have traffic control batons (preferably the LED type) for regulating the traffic during night time. 14 In addition to the delineation devices, all the construction workers should wear fluorescent safety vests and helmets to be visible to the motorists at all times. There should be provision for lighting beacons and illumination for night constructions. 15. The ASCL/ PIU and contractor will coordinate with the local administration and traffic police regarding the traffic signs, detour, and any other matters related to traffic. The contractor will prepare the traffic management plan in detail and submit it along with the EMP for the final approval.

Appendix 11: Sample Chance find Protocol Introduction Project town being a heritage town, there are possibility of any chance finds (artefacts) recovery during excavations. Contractors working at heritage towns must take additional care not to destroy or damage historic features during excavations. There may be many buried historic features in heritage towns such as – idols, toys, wells, ancient drains, remains of buildings, other walls, grain pits, etc. Every care must be made not to destroy these during excavations. Excavator drivers need to be instructed to be aware of hitting buried features and that they must be investigated before continuing work. When features are encountered during mechanical excavation, work should stop and the PIU/Consultants engineers must be informed immediately so that they can be inspected at the first opportunity.

When historic features such as walls, brick constructions and other features are encountered during excavation the excavation must be stopped immediately and the PIU/Consultants must be informed immediately.

1.1 Contractors’ instruction: As soon as contractor recovers any chance find during any

excavation works for pipe laying, they should immediately inform PIU/Consultant present in town about the chance find recovery. Immediately stop the excavation activity near point of recovery. After PIU/consultants engineers come at site, contractor should follow cleaning and photography in supervision of PIU/Consultant engineers.

1.2 Cleaning - When a feature/chance find is discovered it must be defined by careful cleaning. Roots must be removed and dirt must be carefully cleaned away. The section or trench base should also be cleaned back for a little distance around the feature.

1.3 Record photography – When the feature is clean good photography should be taken –

vertical and face-on shots and a few general shots of the feature, also showing its position in relation to surrounding features, buildings, etc. The photographed should be catalogued (date, location, direction of shot)

1.4 Drawn record -When features/chance finds are revealed a drawn record should also be made.

a. General location record – measuring its position and orientation within the protected

site / in relation to surrounding structures

b. Record drawings – detail drawings made in plan and section/profile. The extent (edges) of the feature should be drawn and the level of the existing ground surface and the top and base of the feature should be recorded. These levels should be marked on the drawings. The drawings should include detail of the construction of the feature. Perspective sketches could also be made if necessary. Explanatory notes can also be put on the drawings.

1.5 Reporting finds - When finds are made these should be reported to PIU/Consultants.

Photographs and record drawings should be sent.

584 Appendix 11

1.6 Discovery of historic objects - When clearance and excavation takes place artifacts and

historic objects are sometimes found. These should be recovered and kept in a safe place. The place of discovery should be recorded and each find given a number and tag tied to the find with the same number on it. A list of the finds should be kept (with the find No. And place of discovery and date of discovery recorded).

1.7 PIU/Consultants responsibility- PIU/Consultants should inform in written to the State Archaeological Department at the earliest with photographs and request to Archaeology Department to visit the site and hand over the chance finds to them.
