1.0 BACKGROUND Under the Africa WAPP APL 1 2nd Phase Coastal Transmission Backbone Project, a comprehensive parallel financing plan has been put in place for the development of the 330kV Coastal Transmission Backbone of WAPP, a priority for the Revised ECOWAS (Generation and Transmission) Master Plan. Components of the project being implemented in Ghana by the VRA with a loan from the World Bank are described in Section 2 below, and consist of:

• Component 1: Transmission Infrastructure Development • Component 2: Upgrade of System Control Centres and SCADA/EMS • Component 3: Upgrade of Strategic Power Generation Stations • Component 4: Institutional Capacity Building Support

This Environmental Management Plan (EMP) for the management of the Phase 2 projects is aimed at ensuring sound environmental management of project implementation in accordance with the VRA’s Corporate Environmental Policy and the World Bank’s Environmental Assessment Policy OP4.01. The scope of the EMP focuses on two issues: 1) Management of construction impacts (identification and mitigation of impacts by

construction contractors); and 2) Environmental audits of substations and switchyards to identify any needed environmental

site remediation. The substations and switchyards to be covered under the audits include Volta Substation (Tema), Akosombo Substation, and the Kpong Generation Station.

2.0 DESCRIPTION OF THE PROJECT The work being undertaken includes the following: Component 1: Transmission Infrastructure Development

a. Sub-Station Expansion Works at Volta and Akosombo. This sub-component includes works to expand the capacity of the above two substations, so as to accommodate the Volta-Mome Hagou segment of the Coastal Transmission Backbone (CTB). The substation expansion works will be procured in two packages as follows:

(i) Package A: Supply and installation of (a) 330 kV power equipment (circuit breakers, disconnect switches, capacitive voltage transformers, post insulators and communication line traps) at the Volta sub-substation; (b) control, relaying and metering systems; (c) cabling systems, grounding, bus works and connections; and (d) steel structures.

(ii) Package B:. Supply and installation of (a) 161 kV power equipment (phase shifting transformer, circuit breakers, disconnect switches, capacitive voltage transformers, surge arrestors, post insulators and communication line traps) at the Akosombo sub-substation; (b) control, relaying and metering systems; (c) cabling systems, grounding, bus works and connections; and (d) steel structures.

b. Installation of 3rd Bulk Supply Point for the Accra/Tema Load Centers. This sub-component is to be executed as a single responsibility contract to design, manufacture, test, deliver to site and install (a) 161kV/33kV High Voltage sub-station; and (b) 33kV/11 kV Medium Voltage sub-station. c. Upgrade of Switchgear at the Kpong Generation Station.This sub-component will replace (i) over-aged circuit breakers and disconnects, for which essential spares are no longer available; and (ii) obsolete electromechanical relays on the Akosombo –Volta transmission circuits. It involves a turnkey contract to design, manufacture, testing and erection of substation equipment, such as circuit breakers and disconnection switches, protection and control facilities, that would assure efficient and reliable power evacuation from the Kpong Generation Station into the CTB. Component 2: Upgrade of System Control Centres and SCADA/EMS

a. SCADA/EMS Upgrade for Ghana 161 kV southern transmission loop. This sub-component will upgrade the communications system (closing the FO cable loop between Obuasi/Kumasi, provision of FO terminal equipment at Tafo, Nkawkaw and Konongo, upgrade the FO terminal equipment along the 161 kV coastal network and between Akosombo and Volta, via Akuse, provide 2-channel broadband PLC links, etc.) and upgrade metering equipment (replace faulty CTVs, outmoded RTUs and faulty CTs).

Component 3: Upgrade of Strategic Power Generation Stations

a Rehabilitation of Cranes and Rust Treatment of Cranes and Penstocks at the Akosombo Generation Station.

This sub-component will cover (i) rehabilitation of the Intake Crane at the Akosombo Generating Station, and (ii) rust treatment and painting of the Power House Crane and Penstocks at the Akosombo Generating Station. b. Preparation of EMP for Akosombo and Kpong Generation Stations. This component will involve procurement by VRA of Consulting Services, financed by IDA, to assist in the preparation of an EMP for the Akosombo and Kpong Generation Stations. The development and implementation of “Emergency Preparedness Plans” shall constitute a subset of the EMP. Component 4: Institutional Capacity Building Support

a. Equipment for the VRA Training Centre in Support of the WAPP Organisation This component will involve (i) Modular Power Plant Simulator (Generation, Transformation, Transport, Distribution and Consumption); (ii) Construction of 330kV Line Training Field; (iii) Building technical capability of staff ; (iv) Development of specific training modules (e.g. Thermal Generation) and (v) Building learning resource centre to provide support and training for learners (Computers & accessories, library, books, logistics etc)

3.0 SUMMARY OF potential IMPACTS and MITIGATION MEASURES Potential construction impacts and mitigation measures, by project component and activity, are described in Table 1. Within 6 months of project effectiveness, environmental audits will be carried out to identify any needed environmental site remediation at Volta Substation (Tema), Akosombo Substation, and the Kpong Generation Station. VRA will follow up on the audits by undertaking any needed remediation work. The audits will look for such things as already contaminated soils that need removal and safe disposal, adequacy of existing drainage systems to prevent the escape of pollutants, solid waste management, etc. These audits may be part of normal technical audits already programmed, or may be conducted independently, depending on timing. VRA already uses EPA-approved procedures for disposing of waste oil and sludge from, for example, circuit breakers. These and other standard environmental management procedures at these facilities are described in Annex 2. 4.0 ENVIRONMENTAL MONITORING PROGRAMME A monitoring programme to ensure an effective compliance monitoring of the contractors who will be engaged on the various projects described in Section 3 above, is described in Table 2. The table also details parameters to be monitored, monitoring locations, frequency of monitoring as well as individuals/units responsible for monitoring various impacts identified and ensuring compliance with the mitigation measures.

5.0 INSTITUTIONAL ARRANGEMENTS FOR MONITORING CONSTRUCTION ENVIRONMENTAL & SOCIAL IMPACTS

VRA’s corporate organizational arrangements for managing the environmental and social impacts of it’s operations are shown in Figure 1. Environmental concerns are the responsibility of Project Environmental Officers, while social concerns are the responsibility of Surveyors, Valuers and Compensastion Officers, all reporting through their respective managers and directors to the Deputy Chief Executive (Resources and Services).

6.0 SCHEDULE AND REPORTING Reporting of environmental compliance and mitigation activities of the contractors during the project implementation will be done by the Project Environmental Coordinator through monthly/quarterly/ reports to the Director, Environment & Sustainable Development Department through the Manager, Environment and Social Impact. Reports on social and other compensation


4

issues will be submitted to the Director, Real Estates Department. The Directors, ESD and RED shall provide such information to the Project Director (Director, ED&C) as inputs for project reports. At the end of each year of project implementation, an Annual Environmental Report covering the environmental and social impact monitoring activities carried out by the contractors and other VRA client departments will be prepared and submitted to the Ghana EPA, funding agencies and other stakeholders.

7.0 COST ESTIMATES AND SOURCE OF FUNDS The costs of implementing this Environmental Management Plan (EMP) will come from two sources: 1) Costs for managing construction impacts by contractors will be included in contract costs, and will thus be funded from the World Bank loan. Overall costs cannot be estimated since many EMP requirements are not separately costed in bidding documents. 2) Disposal of waste oils, fuels and other hazardous materials will by done by the VRA with funds from its established corporate operational budget. Actual costs will be small and not readily estimated until actual disposal requirements are identified.

ANNEX 1 Environmental Clauses in Construction Contract Agreements 1. If an Environmental Impact Assessment (EIA) and/or an Environmental Management Plan (EMP) was prepared for this particular Project, before the order to commence any works the Contractor is required to prepare his own EMP for each subproject within a Lot as specified in the EIA/EMP. The plan shall spell out how the Contractor will achieve environmental targets and objectives specified in the EIA/EMP. The Contractor’s EMP shall include, to the extent practicable and reasonable, all steps to be taken by the Contractor to protect the environment in accordance with the current provisions of national environmental regulations and/or the EIA/EMP for this project. The Contractor’s EMP shall follow the format shown in Box 1A. 2. Not withstanding the Contractor’s obligation under the above clause, the Contractor shall implement all measures necessary to restore the sites to acceptable standards and abide by environmental performance indicators specified in the EIA/EMP to measure progress towards achieving objectives during execution or upon completion of any works. These measures shall include but not limited to the following:

(a) Minimize the effect of dust on the surrounding environment resulting from earth mixing sites, asphalt mixing sites, dispersing coal ashes, vibrating equipment, temporary access roads, etc. to ensure safety, health and the protection of workers and communities living downwind of dust producing activities.

(b) Ensure that noise levels emanating from machinery, vehicles and noisy construction activities are kept at a minimum for the safety, health and protection of workers within the vicinity of high noise levels and communities near rock - blasting areas. (c) Ensure that existing water flow regimes in rivers, streams and other natural or irrigation channels is maintained and/or re-established where they are disrupted due to civil works being carried out. (d) Prevent bitumen, oils, lubricants and waste water used / produced during the execution of works from entering into rivers, streams, irrigation channels and other natural water bodies/reservoirs and also ensure that stagnant water in uncovered borrow pits is treated in the best way to avoid creating possible breeding grounds for mosquitoes. (e) Prevent and minimize the impacts of quarrying, earth borrowing, piling and building of temporary construction camps and access roads on the biophysical environment including protected areas and arable lands; local communities and their settlements. In as much as possible restore/rehabilitate all sites to acceptable standards. (f) Upon discovery of ancient heritage, relics or anything that might or believed to be of archaeological or historical importance during the execution of works report such findings to National Commission on Culture (NCC) in fulfilment of the measures aimed at protecting such historical or archaeological resources.


11

(g) Discourage construction workers from engaging in the exploitation of natural resources such as hunting, fishing, collection of forest products or any other activity that might have a negative impact on the social and economic welfare of the local communities.

(h) Implement soil erosion control measures in order to avoid surface run off and prevents siltation etc. (i) Ensure that garbage, sanitation and drinking water facilities are provided in construction workers camps. (j) Ensure that in as much as possible, local materials are utilized to avoid importation of foreign material and long distance transportation.

(k) Ensure public safety and meet traffic safety requirements for the operation of work to avoid accidents.

3. The Contractor shall indicate the period within which he/she shall maintain status on site after completion of civil works to ensure significant perturbations arising from such works have been taken into account. 4. The Contractor shall adhere to the proposed activity implementation schedule and the monitoring plan / strategy to ensure effective feedback of monitoring information to both project management and the Director / EPA so that impact management can be implemented properly, and if necessary, adapt to changing and unforeseen conditions. 5. Besides the regular inspection of the sites by Site Supervisor for adherence to specification, the Consultant for Engineering Supervision shall appoint an Inspector to oversee the compliance with and to inspect significant sites where works have been carried out and proposed mitigation measures implemented and shall give certification regarding the adequacy or inadequacy of rehabilitation measures carried out on the bio-physical environment and compensation for socio-economic disruption resulting from implementation of any works. 6. If the Contractor fails to implement the approved Environmental Management Plan after written instruction by the Engineer to fulfil his obligation within the requested time, the Client reserves the right to arrange through the Engineer for execution of missing action by third party on account of the Contractor.

Worksite/Campsite Waste Management 7. All vessels (drums, containers, bags, etc.) containing oil/fuel/surfacing materials and other hazardous chemicals must be bunded in order to contain spillage. All waste containers litter and any other waste generated during the construction shall be collected and disposed off at designated disposal sites in line with the Waste Management Regulations of the Environmental Protection Agency of Ghana.


12

8. All drainage and effluent from storage areas, workshops and camp sites shall be captured and treated before being discharged into the drainage system in line with the Water Pollution Control Regulations of the Environmental Protection Agency of Ghana. 9. Used oil from maintenance shall be collected and disposed off appropriately at designated sites or be re-used or sold for re-use locally.

10. Entry of runoff to the site shall be restricted by constructing diversion channels or holding structures such as banks, drains, dams, etc. to reduce the potential of soil erosion and water pollution. 11. Construction waste shall not be left in stockpiles along the road. Waste and other excess material shall be used for rehabilitating borrow areas and landscaping around the road. 12. If other spoil disposal sites are necessary, they shall be located in areas, approved by the Engineer, of low land use value and where they will not result in material being easily washed into drainage channels. Whenever possible, spoiled materials should be placed in low-lying areas and should be compacted and planted with species indigenous to the locality.

Material Excavation 13. Contractors will have to indicate the source of material such as gravel for concrete production, sand bedding of pipes or any other purpose. 14. Contractors shall obtain appropriate licenses/permits from relevant authorities to operate quarries or borrow areas. 15. The location of quarries and borrow areas shall be subject to approval by relevant authorities including traditional authorities if the land on which the quarry or borrow areas fall in traditional land and by the Environmental Protection Agency of Ghana. 16. New Extraction sites shall not be located in the vicinity of settlement areas, cultural sites, wetlands or any other valued ecosystem component and shall not be located at less than 10km from such areas. 17. New Extraction sites shall not be located adjacent to stream channels wherever possible to avoid siltation of river channels. Where they are located near water sources, borrow pits and perimeter drains shall surround quarry sites. 18. New Extraction sites shall not be located in forest reserves. However, where there are no other alternatives, permission shall be obtained from the Ministry of Lands Forestry and Mines and an environmental impact study shall be conducted. 19. New Extraction sites shall not be located on high or steep ground or in areas of high scenic value.


13

20. Only sites that can easily be rehabilitated shall be chosen. Areas with minimal vegetation cover such as flat and bare ground or areas covered with grass only or covered with shrubs with height of less than 1.5 m. 21. New Extraction site boundaries shall clearly be demarcated and marked to minimize vegetation clearing. 22. Vegetation clearing shall be restricted to the area required for safe operation of construction work. Vegetation clearing shall not be done more than three months in advance of operations. 23. New Extraction sites shall not be located in archaeological areas. Excavations in the vicinity of such areas shall proceed with great care and shall be done in the presence of NHCC staff. 24. Stockpile areas shall be located in areas where trees can act as buffers to prevent dust pollution. Perimeter drains shall be built around stockpile areas. Sediment and other pollutant traps shall be located at drainage exist from workings

Material Deposit 25. The Contractor shall deposit any excess material in accordance with the principles of the EMP at areas approved by local authorities and/or the Engineer. 26. The Contractor has in advance of the commencement of work clarify with the local authorities dumpsites or areas for hazardous deposits for contaminated liquid and solid materials, that can not be used any longer as backfill.

Rehabilitation and Soil Erosion Prevention 27. To the extent practicable rehabilitate the site progressively so that the rate of rehabilitation is similar to the rate of construction. 28. Always remove and retain topsoil for subsequent rehabilitation. Soils shall not be stripped when they are wet as this can lead to soil compaction and loss of structure. 29. Topsoil shall not be stored in large heaps. Low mounds of no more than 1 to 2m high are recommended. 30. Re-vegetate the stockpile to protect the soil from erosion, discourage weeds and maintain an active population of beneficial soil microbes. 31. Locate stockpiles where they will not be disturbed by future construction activities. 32. To the extent practicable reinstate natural drainage patterns where they have been altered or impaired. 33. Remove toxic materials and dispose of them in designated sites. Backfill excavated areas with soils or overburden that is free of foreign material that could pollute ground water and soil.


14

34. Identify potentially toxic overburden and screen with suitable material to prevent mobilization of toxins. 35. Ensure the reshaped land is formed so as to be inherently stable, adequately drained and suitable for the desired long-term land use and that would allow natural regeneration of vegetation. 36. Minimize the long-term visual impact by creating landforms, which are compatible with the adjacent landscape. 37. Minimize erosion by wind and water both during and after the process of reinstatement. 38. Compacted surfaces shall be deep ripped to relieve compaction unless subsurface conditions dictate otherwise. 39. Revegetate the area with plant species that will control erosion, provide vegetative diversity, and that will through succession, contribute to a stable and compatible ecosystem. The choice of plant species for rehabilitation shall be done in consultations with local research institutions, forest department and the local people, as they will be long-term beneficiaries.

Water Resources Management 40. The Contractor shall at all costs avoid conflicting with water demands of local communities. 41. Abstraction of both surface and underground water shall only be done with the consultation of the local community and after obtaining a permit from the relevant Water Authority. 42. Abstraction of water from wetlands shall be avoided. Where necessary, authority has to be obtained from relevant authorities. 43. Temporary damming of streams and rivers shall be done in such a way that disruption of water supplies to communities down stream is avoided and maintain the ecological balance of the river system 44. No construction water containing spoils or site effluent especially cement and oil shall be allowed to flow into natural water drainage courses. 45. Wash water from washing out of equipment shall not be discharged into water courses or road drains. 46. Site spoils and temporary stockpiles shall be located away from the drainage system and surface run off shall be directed away from stockpiles to prevent erosion

Traffic Management


15

47. Location of access roads/detours shall be done in consultation with the local community especially where access road shall traverse important ecosystem component. Access roads shall not traverse wetland areas. 48. Upon the completion of civil works, all access roads shall be ripped and rehabilitated. 49. Access roads shall be sprinkled with water at least five times a day in settled areas and three times in unsettled areas to suppress dust emissions.

Blasting 50. Blasting activities shall not take place in the vicinity of settlement areas, cultural sites, or wetlands without the permission of the Engineer. 51. Blasting activities shall be done during working hours and local communities shall be consulted on the proposed blasting times. 52. Noise levels reaching the communities from blasting activities shall not exceed 90 decibels.

Disposal of Unusable Elements 53. Unusable materials and construction elements such as electro-mechanical equipment, pipes, accessories and demolished structures will be disposed of in a manner approved by the Engineer. The Contractor has to agree with the Engineer which elements are to be surrendered to the Clients premises, which will be recycled or reused, and which will be disposed of at approved landfill sites. 54. As far as possible, unused pipelines shall remain at their current position. Where for any reason no alternative alignment for the new pipeline is possible, the old pipes have to be stored at a safe place to be agreed upon with the Engineer and the local authorities concerned. 55. AC-pipes as well as broken parts thereof have to be treated as hazardous material and deposed subsequently as indicated before. 56. Unsuitable and demolished elements shall be dismantled to size fitting on ordinary trucks for transport.

Health and Safety 57. The Contractor in advance of the construction work shall mount an awareness and hygiene campaign. Workers and local residents shall be sensitized on health risks particularly of AIDS. 58. Adequate road signs to warn pedestrians and motorists of construction activities, diversions, etc. shall be provided at appropriate points.


16

59. Construction vehicles shall not exceed maximum speed limit of 40km per hour.

Repair of Private Property 60. Wherever the Contractor, whether deliberately or incidentally damages private property, it has to be repaired at the Contractor’s cost. For each repair, the Contractor has to obtain from the owner a certificate that the damage has been made good satisfactorily in order to indemnify the Client from subsequent claims. 61. In case where compensation for inconveniences, damage of crops etc. are claimed by the owner, the Client has to be informed by the Contractor through the Engineer. This compensation is in general settled under the responsibility of the Client before signing the Contract. In unforeseeable cases, the respective administrative entities of the Client will take care of compensation. Contractor HSES Management Plan 62. In order to ensure that the Contractor is fully aware and prepared for the management of health, safety, environmental and social (HSES) aspects of the project, the Contractor(s) of the works is required to prepare an HSES Management Plan (HSES-MP) for the specific works to be executed under his contract within 6 weeks after signing of the Contract. The Contractor’s HSES-MP will serve two main purposes:

• For the Contractor, for internal purposes, to ensure that all measures are in place for adequate HSES management, and as an operational manual for his staff.

• For the Client, supported where necessary by a Supervising Engineer (SE), to ensure that the Contractor is fully prepared for the adequate management of the HSES aspects of the project, and as a basis for monitoring of the Contractor’s HSES performance.

63. The Contractor’s HSES-MP should provide: • an overview of the HSES aspects and impacts related to construction works. • relevant Ghanaian legislation and Ghanaian and WB standards to which the Contractor

will comply, including the way in which he will monitor such compliance, specifying: o Standards against which the monitoring will be set (national and WB), o Which parameters and limits will be monitored, o Frequency at which monitoring will be undertaken.

• a clear definition of specific mitigation measures that are intended to be implemented in order to minimize the impacts; and

• the internal organisational, management and reporting mechanisms put in place for such. 64. The Contractor’s HSES-MP will be reviewed and approved by the Client before start of the works. This review should demonstrate if the Contractor’s HSES-MP covers all of the identified impacts, and has defined appropriate measures to counteract any potential impacts. HSES Reporting 65. The Contractor is required to prepare weekly progress reports, which shall contain, among others, safety statistics, including details of any hazardous incidents and activities related to other HSES aspects. In line with this requirement it should be expected that the Contractor report on:


17

• HSES management actions/measures taken; • Problems encountered in relation to HSES aspects (incidents, including delays,

cost consequences, etc. as a result thereof); • (Lack of) compliance with contract requirements on the part of the Contractor; • Changes of assumptions, conditions, measures, designs and actual works in

relation to HSES aspects; and • Observations, concerns raised and/or decisions taken with regard to HSES

management during site meetings. 66. A sample reporting format for HSES reporting by Contractors is presented in Box 1B. The form is to be completed by the Contractor, and could serve as the basis for discussions on HSES during the weekly progress meetings between Contractor, ESE and the Client’s Project Engineer. After review, the report should be approved by the ESE. 67. It is advised that reporting on incidents shall be done “as soon as practicable”.

Such incident reporting shall therefore be done individually. Also, it is advised that the Contractor is required to keep records and make reports on health, safety and welfare of persons, and damage to property. It is advisable to include such records, as well as copies of incident reports as Appendixes to the weekly reports. A sample incident report is presented in Box 1C. The Contractor may, however, want to choose his own format. Details of HSES performance will be reported to the Client through the Engineer in the SE’s reports to the Client.

Training of Contractor’s Personnel 68. The Contractor shall provide sufficient training to his own personnel to ensure that they are all aware of the relevant aspects of the EMP and are able to fulfil their roles and functions (Contractor’s responsibility). Specific training should be provided to those employees that have specific tasks associated with the implementation of the EMP. General topics should be:

• HSES in general (working procedures); • emergency procedures; and • social and cultural aspects (awareness raising on social issues).

Cost of Compliance 69. It is expected that compliance with these conditions is already part of standard good workmanship and state of art as generally required under this Contract. The item “Compliance with Environmental Management Conditions” in the Bill of Quantities covers these costs. No other payments will be made to the Contractor for compliance with any request to avoid and/or mitigate an avoidable negative environmental impact.

ANNEX 2 VRA Standard Environmental Management Procedures Environmental Management Programme

Progress towards achieving environmental objectives and targets set at the start of each year (detailed as the Work Programme) is monitored regularly by the Director, Environment & Sustainable Development Department and is reported on to the Chief Executive through the Deputy Chief Executive (Resources and Services). Objectives and targets are reviewed as and when necessary. The Authority’s current objectives and targets are described in the Corporate Environmental Work Programme. Where new developments or modified activities take place in the Authority, the environmental programme is reviewed and amended where relevant and appropriate. The Environmental Work Programme incorporates: • Key Effectiveness Areas (specific activities/programmes), • Annual/Quarterly Targets to be achieved, • Units of measure of performance, • Responsible officer for achievement of set targets.

Oily Waste Management at Substations/Switchyards Oily water waste generated at the substations/switchyards are minimal; these are collected via oil treatment equipment/machines, stored in containers and disposed of in accordance with provisions of the Environmental Management Plan for the Disposal of Oily Waste/Sludge developed in consultation with the Ghana EPA. Solid Waste Management Solid waste from VRA town sites and plant operation that cannot be recycled is collected and taken to an approved off-site waste disposal facility. At some locations, contract arrangements have been made with the waste management departments of Metropolitan Authorities to collect all solid waste on regular basis. Sewage Treatment and Disposal Sewage from offices, plant and housing complexes at VRA townships are discharged into sewage ponds for treatment in extended natural aeration systems prior to disposal into receiving water body. In addition to this, sewage at other VRA stations is managed as per Metropolitan/ District Administration processes approved by the Ghana EPA.

Hazardous Materials Management Oil contaminated wastes such as waste rags and foam material normally used in cleaning oil spills during routine plant maintenance activities are collected in polyethylene waste bags and disposed of in High Density Polyethylene (HDPE) lined excavated pits on plant premises. Oil contaminated sandy material are similarly disposed of in HDPE lined excavated pits. Chemicals for weed control at the substations/switchyards are procured in accordance with EPA guidelines and obsolete ones are stored and disposed of in consultation with the Ghana EPA (Chemicals Control Management Centre).

Storm water Management Rainwater and surface runoff are discharged through the existing drainage at the sites into receiving water bodies. Right of Way Vegetation Control This is carried out through periodic manual slashing and only chemicals approved by the EPA are applied at the tower bases. As much as practicable vegetation control is done so as to reduce erosion on access tracks and damage to food crops where available. Vegetation control in forest reserves is done in consultation with the Forestry Services Department (FSD) as per memorandum of understanding between VRA and FSD.
