There are four monitoring programs and two physical works including: a) Lower Whatshan River Fish Habitat Enhancement Physical and Biological Effectiveness Monitoring b) Reservoir Vegetation Monitoring c) Reservoir Wildlife Monitoring d) First Nations Heritage and Archaeology Monitoring e) Habitat Complexing Assessment and Enhancement Structures f) Inonoaklin Recreation Site Boat Launch Extension 2 Background The water use planning process for BC Hydro’s Whatshan project was initiated in May 2002 and completed in May 2003. The conditions proposed in the WUP for the operation of the project reflect the October 2003 recommendations of the WUP Consultative Committee. In August 2003, the Whatshan WUP was submitted to the Comptroller of Water Rights (Comptroller). On 14 July 2005, BC Hydro was ordered to implement the conditions proposed in the Whatshan WUP and prepare the monitoring programs and physical works terms of reference (TOR). On 14 November 2005, the Whatshan WUP monitoring programs and physical works TOR were submitted to the Comptroller for review and approval. On 15 February 2006, the TOR for the Lower Whatshan River Fish Habitat Enhancement Physical and Biological Effectiveness Monitoring, Reservoir Vegetation Monitoring and Reservoir Wildlife Monitoring programs and the physical works TOR were accepted by the Comptroller. As requested by the Comptroller, BC Hydro will revise the TOR to reflect work not requiring a permit under the BC Heritage Conservation Act to include a non-intrusive archaeological overview assessment of the drawdown zones of Whatshan Lake Reservoir. BC Hydro will work with the First Nations to develop a plan to meet the obligations required under the BC Heritage Conservation Act. BC Hydro Page 1 Whatshan Project Water Use Plan Monitoring Programs and Physical Works Annual Report: 2006 On 12 June 2006, revised Whatshan WUP physical works TOR were submitted to the Comptroller for review and approval. To date, these TOR have not been accepted by the Comptroller. As outlined in the Whatshan WUP, BC Hydro will review the results of the monitoring programs five years after implementation of the WUP. A formal review of the WUP is recommended in ten years. A review could be triggered sooner if significant risks are identified through the analysis of monitoring results. 3 Status The following table outlines the status and schedule for the Whatshan WUP monitoring programs and physical works.

The Whatshan WUP Consultative Committee expressed concern that low flows in the lower Whatshan River from the Whatshan Dam to Arrow Lake may affect fish habitat and fish populations. To benefit rainbow trout in Reach W3, the Consultative Committee agreed to examine the feasibility and, if feasible, install 15 to 20 habitat BC Hydro Page 2 Whatshan Project Water Use Plan Monitoring Programs and Physical Works Annual Report: 2006 enhancement structures in reach W3 in lieu of a minimum flow release from the dam (see Section 5.1 below for construction of enhancement structures). The TOR describe a monitoring program that will evaluate the benefits of these structures to fish habitat and, consequently, to fish abundance in Reach W3 of the lower Whatshan River. Monitoring indicators will include measures of: a) Physical habitat. b) Fish abundance and biological characteristics. These indicators will be measured prior to and following installation of the habitat structures to evaluate the benefits of the structures. This monitoring program includes two major components: monitoring physical habitat and longevity of structures; and monitoring biological response with a before-after approach. 4.1.2 Status This monitoring program was initiated in May 2006 and will be carried out over ten years, occurring in years 1, 2, 4, 7 and 10. The first program report is expected in April 2007. 4.1.3 Interpretation of Data At this time there is no data to interpret for this monitoring program. 4.2 4.2.1 Reservoir Vegetation Overview The objective of this monitoring program is to reduce uncertainty related to the effects of reservoir operations on reservoir vegetation in the Whatshan Lake Reservoir. The Whatshan WUP Consultative Committee expressed concern that changes to the operation of the Whatshan Lake Reservoir would affect emergent and submergent vegetation in the drawdown zone of the reservoir. Reservoir vegetation is sensitive to the frequency and duration of inundation such that vegetation communities present at various elevations in the drawdown zone are determined by historic reservoir operations. Changes to reservoir operations recommended in the WUP were designed to benefit recreation and fish in the reservoir, and include reservoir elevations with approximately 1 m less drawdown during the winter and higher reservoir elevations during May and June. It was hypothesized that WUP operations may reduce the extent of emergent vegetation and increase the extent of submergent vegetation. However, this response was highly uncertain, and the Consultative Committee recommended that reservoir vegetation be monitored. BC Hydro Page 3 Whatshan Project Water Use Plan Monitoring Programs and Physical Works Annual Report: 2006 Monitoring indicators will include measures of: a) Emergent and submergent vegetation spatial extent. b) Emergent and submergent vegetation species composition. c) Emergent and submergent vegetation relative productivity. These indicators will be measured using aerial photography both prior to and following implementation of new reservoir operations. This monitoring program involves mapping of vegetation communities from air photos, ground-truthing of the air photo mapping, data entry, and reporting. 4.2.2 Status This monitoring program was initiated in May 2006 and will be carried out over ten years, occurring in years 1, 6, and 10. Efficiencies were realized in the proposal stage around air photo methodologies and additional air photo collection may occur as budgets permit. The first program report is expected in April 2007. 4.2.3 Interpretation of Data At this time there is no data to interpret for this monitoring program. 4.3 4.3.1 Wildlife Monitoring Overview The objective of this monitoring program is to reduce uncertainty in the relationship between wildlife and reservoir vegetation. The Whatshan WUP Consultative Committee expressed concern that changes to the operation of the Whatshan Lake Reservoir might affect wildlife species that use littoral and riparian habitats near the reservoir. During the Whatshan water use planning process, many hypotheses were proposed for the effects of reservoir operations on wildlife. The Consultative Committee recommended that reservoir wildlife be monitored to provide information to help make more informed decisions during future water use planning processes. The wildlife monitoring program is designed to: 1. Provide information on the relationship between reservoir wildlife and aquatic (emergent and submergent) or riparian vegetation; and 2. Infer how wildlife responds to the changes in vegetation, which will be documented by the vegetation monitoring program. Specific monitoring variables will be determined during the program design and pilot survey component in year 1. This monitoring program involves: developing a detailed monitoring program design and associated pilot survey in year 1, annual volunteer surveys in years 2 to 10, and analysis and reporting of monitoring results in year 10. BC Hydro Page 4 Whatshan Project Water Use Plan Monitoring Programs and Physical Works Annual Report: 2006 4.3.2 Status This monitoring program is scheduled to be initiated in May 2006 and will be carried out over ten years. The first program report is expected in April 2007. 4.3.3 Interpretation of Data At this time there is no data to interpret for this monitoring program. 4.4 4.4.1 First Nations Heritage and Archaeology Monitoring Overview As per the Whatshan WUP Order dated 14 July 2005, BC Hydro submitted a monitoring program TOR for acceptance by the Comptroller outlining the details of a study to locate archaeological sites within the reservoir between the elevations of 634.4 and 641.3 metres. The objective of the archaeological inventory is to identify and record archaeological resources in the drawdown zone of the Whatshan Lake Reservoir and to describe the archaeological significance and elevations of these sites relative to the reservoir operation range. During the Whatshan water use planning process, a preliminary assessment of archaeological resources in the Whatshan area was completed (Choquette, 2002)1. Whatshan Lake Reservoir was created well before any systematic archaeological investigations were required for developments such as hydroelectric reservoirs. Therefore, the archaeological values of the original lakeshore and riverbank settings along with the adjacent terrain were never identified, recorded, or subject to salvage data retrieval. The report prepared by Choquette concluded that based on available information no operational changes were necessary to address archaeological concerns. However, this conclusion is based on an incomplete understanding drawn from historic information from unauthorized relic collectors and a very brief survey of the uppermost part of the drawdown zone. Choquette further recommended that a systematic survey of the reservoir drawdown area be completed when the reservoir is at its lowest elevation in order to properly inventory the archaeological resources in the drawdown zone. This information would be used in future water use planning processes to inform the assessment of options for operations of the reservoir. 4.4.2 Status This monitoring program is on hold pending approvals and clarification. As requested by the Comptroller, BC Hydro will revise the TOR to reflect work not requiring a permit under the BC Heritage Conservation Act to include a non-intrusive archaeological overview assessment of the drawdown zones of Whatshan Lake 1 Choquette, Wayne. 2002.

BC Hydro will work with the First Nations to develop a plan to meet the obligations required under the BC Heritage Conservation Act. 4.4.3 Interpretation of Results At this time there is no data to interpret for this monitoring program. 5 Whatshan WUP Physical Works This section outlines the status of the Whatshan WUP physical works as per the Order under the Water Act, dated 14 July 2005. 5.1 5.1.1 Habitat Complexing Assessment and Enhancement Structures Overview The objective of this physical work is to achieve effective river habitat in the lower Whatshan River. During the Whatshan water use planning process it was noted that effective river habitat in the lower Whatshan River could be achieved through changes in operation of the Whatshan Reservoir Lake but that such changes would be costly. In lieu of the operational changes, it was determined that equivalent benefits to fish habitat could be achieved with the addition of about 15 to 20 complexing structures in Reach 3 of the river. The Consultative Committee recommended construction of physical works in Reach 3. Prior to the complexing structures being designed and installed, an assessment of habitat complexing potential and rainbow trout population monitoring in the Reach is to be undertaken. It is expected that this assessment and monitoring work will take two years to complete. Design of the structures will follow the assessment work. Upon approval of these designs by the Comptroller, BC Hydro will proceed with construction of the habitat complexing structures. 5.1.2 Status This physical work was initiated in May 2006 and will be carried out over three years. The first physical work report is expected as part of the Lower Whatshan River Fish Habitat Enhancement Physical and Biological Effectiveness Monitoring report in April 2007. On 12 June 2006, the Habitat Complexing Assessment and Enhancement Structures TOR were revised to reflect a modification to the implementation schedule and were submitted to the Comptroller for review and approval. To date, this TOR has not been accepted by the Comptroller. 5.1.3 Interpretation of Data At this time there is no data to interpret for this physical work. BC Hydro Page 6 Whatshan Project Water Use Plan Monitoring Programs and Physical Works Annual Report: 2006 5.2 5.2.1 Inonoaklin Recreation Site Boat Launch Extension Overview The objective of the boat launch extension was to enable boat access to the reservoir when the reservoir is as low as 636.5 m. 5.2.2 Status For the Inonoaklin Recreation Site Boat Launch Extension, the scope of the original TOR was to extend the existing boat launch from elevation 638.1 m to deeper water to facilitate launching at a wider range of reservoir operations. BC Hydro received environmental approvals for the original project from the Department of Fisheries and Oceans (DFO) in March 2006. On 1 March 2006, BC Hydro requested permission from the Comptroller for a one time special drawdown to 635 m for the boat ramp installation. Permission was received that day. On 7 March 2006, during the site visit for prospective tenders for the ramp installation contract, it was found that the reservoir floor immediately below the lower end of the existing boat ramp was too shallow to allow an extension of the ramp. Based on discussions with the Inonoaklin Recreation Commission who manage the site for BC Parks (the boat launch is located on a BC Parks Reserve) a new boat ramp located approximately 150 m north of the existing boat launch was deemed suitable. Shortly after the site visit, BC Hydro received permission from the Recreation Commission to construct a boat ramp and associated parking area in this new location. On 7 March 2006, BC Hydro initiated the construction of the new boat ramp given the small window of opportunity to complete this project in the early spring pending the coming freshet. The project was substantially completed on 12 April 2006. Remaining minor works at the top of the ramp, including a barrier gate, signs and nopost-guardrails, will be completed shortly. The Inonoaklin Recreation Site Boat Launch Construction Summary Report was completed. On 12 June 2006, the Inonoaklin Recreation Site Boat Launch Extension TOR were revised to reflect the a new boat ramp located approximately 150 m north of the existing boat launch and were submitted to the Comptroller for review and approval. To date, this TOR has not been accepted by the Comptroller. 6 Whatshan WUP Monitoring Programs and Physical Works Costs The following table summarizes the Whatshan WUP monitoring programs and physical works costs approved by the Comptroller on 15 February 2006 and the actual costs to 31 May 2006.

The previous existing boat launch at the recreation site runs from the reservoir’s normal full level of 641.30 m down to elevation 638.10 m. The existing boat ramp was to be extended but due to insufficient gradient at lower elevations it was not a valid option. Therefore; a second concrete boat launch was constructed within the recreation site 150 m to the left (north) of the existing boat ramp. Appendix 1 contains photos showing the location of the second boat launch. The work was comprised of the excavation for, and placement of, a concrete slab that would be the second boat launch at the Inonoaklin Recreation Site at Whatshan Lake Reservoir. The work included construction of a 3.0 m wide by 100 mm thick reinforced concrete slab that runs from the normal high water level of 641.30 m for Whatshan Lake down to El. 635.50 m. The slab was placed on compacted native gravel. There was no material brought in from other areas for the construction of the boat launch. The construction of the boat launch included the development of a spoil infill area that will be used as a parking area for vehicles/boat trailers. The spoil area is adjacent to the top of the concrete ramp. Whatshan Lake was drafted down to an elevation of 635.0 m to accommodate the construction of the boat launch to ensure all work was conducted in the dry. Construction for the new boat launch began on April 5, 2006 with excavating a rough in grade to determine gradient to the top of the beach. The photos in appendices 1 and 2 show that there was no riparian vegetation removed for the creation of the boat launch. The area in which the boat launch was created was at the edge of the Inonoaklin Recreation Site beach area. Therefore; there was very little vegetation growing in the area. Any vegetation that was removed was for the parking area located at the top of the ramp. Photos located in appendices 2 and 3. Formwork for the concrete began on April 8, 2006 along with pouring 50 ft of cement on the bottom portion of the ramp. There was a berm placed long the bottom edge of the formwork to ensure that concrete runoff would not enter the reservoir. The top portion of the ramp was poured on April 11, 2006. There was a small delay between the two pours due to weather conditions. Appendix 4 contains photos of the concrete formwork and the pouring of the cement. The parking area, beach work and the sloping of the boat launch banks was completed on April 12, 2006. Appendix 5 contains photos showing the finished boat launch and the top parking area. The environmental management plan created for the construction of the Inonoaklin Recreation Site boat launch is located in Appendix 6.

PROJECT DESCRIPTION The Inonoaklin Recreation Site at the Whatshan Lake Reservoir is located about 20 km west of the Needles ferry. The existing boat launch at the recreation site is 3.05 m wide and is constructed from horizontal concrete strips (3.05 m long by 0.36 m wide) that are hooked together. The ramp has a constant grade (slope) of 15%. The existing ramp runs from the reservoir’s normal full level of 641.30 m down to elevation 638.10 m. The existing boat ramp was to be extended but due to insufficient gradient at lower elevations it is not a valid option. Therefore; a second concrete boat ramp is to be constructed within the recreation site 150 m to the left (north) of the existing boat ramp. The work is comprised of the excavation for, and placement of, a concrete slab that will be a second boat ramp at the Inonoaklin Recreation Site at Whatshan Lake Reservoir. The work includes construction of a 3.0 m wide by 100 mm thick reinforced concrete slab that will run form the normal high water level of 641.30 m for Whatshan Lake down to El. 635.50 m. The overall length of the slab, as measured along the surface of the slab will be about 40 m. Apart from the uppermost 1 m of ramp the ramp will be at a constant grade of 15%. The top 1 m of ramp will be at about 10% to allow a smooth transition onto the ramp. There will be no cross fall across the width of the ramp. The slab is to be placed on compacted native gravel. The completed slab will not follow the fall line of the existing bank but will be angled left in a straight line. Also included in the work is the development of a spoil infill area that will be used as a parking area for vehicles/boat trailers. The spoil area is adjacent to the top of the concrete ramp constructed under this contract. Excess native materials from the boat ramp excavation are to be placed in the spoil area, compacted and left level, in a neat and tidy manner. 2. 2.1 ENVIRONMENTAL MANAGEMENT Purpose of the EMP The purpose of this Environmental Management Plan is to identify any elements of the project that could present a hazard to the environment. The plan describes how those risks can be mitigated through proper work management and in the event of an accident, procedures that will contain and limit impacts to the environment. The EMP shall be used as a guide to ensure the use of best management practices; contractors and employees shall follow its intent. Steps will be taken to ensure no deleterious substances enter watercourses that flow into adjacent fish habitat. Any condition which has resulted from operations of this project, which constitutes, or could result in unnecessary damage or disturbance to property and the environment, will be corrected to the satisfaction of BC Hydro environmental staff and the applicable government authorities.

SUMMARY OF ENVIRONMENTAL IMPACTS AND MITIGATION Long term environmental impacts resulting from this project are not expected. Shortterm impacts related to construction are expected to be minimal and easily avoided/mitigated. The environmental concern of this project is the potential for the introduction of harmful or polluting substances into the soil or nearby waterways as a result of activities on site, also for the potential for harmful alteration, disruption or destruction of fish habitat. In particular for the boat launch creation the primary impacts that could arise are introduction of sediment into the aquatic environment during and shortly after excavations and placement of gravel and general fill, fuel and oil spills, or the introduction of concrete or concrete wash water into the aquatic environment. To accommodate the construction of the second boat launch at the Inonoaklin recreation site the Whatshan Reservoir will be drafted down to an elevation of 635.0 m. This allows all the work to be conducted in the dry.

ENVIRONMENTAL MONITORING The Project Manager and Site supervisor will ensure that the EMP is followed. The Environmental Monitor (BC Hydro environmental staff) will visit the site, when necessary to supervise the environmentally sensitive aspects of the project. The monitor will conduct a site visit prior to the commencement of the project, during the shutdown stages of the project and as required during any of the key stages of the project. The environmental monitor (B.C. Hydro technical/professional staff and/or contractor) will have the authority to order the shut-down of the operation if environmental protection is compromised. 5. ENVIRONMENTAL IMPACTS AND MITIGATION This section provides proposed measures to prevent or mitigate adverse environmental effects of the project including identification of measures to prevent equipment malfunction, spills, or accidents. References are made to BC Hydro work procedures contained in the Appendices. Throughout this project, BC Hydro and its contractors will limit disturbance to the environment by abiding by the following practices. Hydro’s Representative or EO will ensure compliance with the requirements identified in this section. BC Hydro Page 24 Whatshan Water Use Plan Physical Works Terms of Reference 5 May, 2006 5.1 Concrete Work Any concrete work must be conducted so that wash water and excess concrete slurry from the site and equipment do not contaminate the reservoir drainage waters. Forming procedures will be of the highest standards to ensure that concrete does not leak into the reservoir. All equipment shall be washed off site, unless provided with an on board wash bucket. The contractor shall find an appropriate wash location away from the construction site that allows for filtration of sediment so as to not discharge directly into fish-bearing water bodies or storm sewers directly connected to fish-bearing water bodies. Concrete finishing tools shall not be cleaned in Whatshan Lake reservoir or any other water courses. Water used for cleaning concrete finishing tools and equipment shall be disposed of in the designated waste area as specified above. 5.2 Watercourse and Water Quality Protection Disturbance to the banks of the reservoir will be minimized and will be confined entirely within the boat launch ramp boarders. No riparian vegetation will be affected other than that within the boarders of the boat launch. No further material will be placed within the drawdown zone of the reservoir other than granular fill as required to stabilize the sub grade. Only native material or clean granular fill will be utilized. No fill will be placed outside of the boarders of the boat launch. The project will not cause debris of any kind to be placed within the reservoir or the drawdown zone of the reservoir. Excavated material that is removed from within the drawdown zone will be placed within the designated spoil area located adjacent to the top of the new ramp. Runoff from the construction sites will not be allowed to enter any established watercourse (this includes seasonably dry water channels and ditches) unless it meets aquatic life criteria specified in the BC Water Quality Guidelines (Criteria): 1998 Edition and the CCME Canadian Water Quality Guidelines. In accordance with these guidelines BC Hydro and its contractor shall perform in a manner that ensures water exiting the work site meets the following parameters. Parameter Suspended Solids Maximum Allowable • 25 mg/l above background when background is between 25 and 250 • 10% when background is ≥ 250 mg/l No oil or grease will be permitted to escape into adjacent drainages and natural watercourses. In the case of a spill, the BC Hydro Oil and Chemical Spill Emergency Response Plan (Appendix 1) must be followed such that no release to watercourses occurs. BC Hydro will periodically monitor water quality parameters. BC Hydro’s EM retains the right and responsibility to suspend site work and to take corrective action if water quality parameters are not in compliance with allowable levels. Work will be suspended until adequate corrective measures have been implemented to the satisfaction of Hydro’s Representative. BC Hydro Page 25 Whatshan Water Use Plan Physical Works Terms of Reference 5 May, 2006 5.3 Oil and Fuel Spills and leaks of oils and fuels can adversely effect terrestrial and aquatic environments if not managed properly. In addition to absorbent materials required to cleanup drips, leaks and minor spills, a fully stocked spill kit must be located on site to deal with any emergency spill situations. Spill kits shall be available where oil filled equipment will be working, and staff and contractors on site will be trained in the proper use of spill kits. Due to the risk of spill and fire, fuels and/or other petroleum or combustible products will not be stored in any large quantity on site. Only small fuel containers, such as approved safety containers or Tidy Tanks properly mounted in trucks will be allowed on site for any extended period of time. All containers must be labelled with appropriate TDG, WHMIS and safety markings. To reduce the risk and the impact of spills: 1. Implement the oil spill response plan (Appendix B). 2. No equipment will enter the wetted portion of the reservoir or any watercourse at any time. 3. All machinery will be serviced and maintained well above the high water line of the reservoir or any watercourse to prevent leaks of fuel or lubricants from entering the reservoir or any watercourse. All equipment will be inspected for leaks and worn hoses and fittings prior to access onto the site and daily thereafter. 4. Place oil sorbent sheets and/or containers under vehicles and equipment parked in high-risk areas (i.e., adjacent to watercourses) for longer than 2 hours or immediately under any vehicle or equipment that is leaking. Leaking equipment must be immediately shut down and repaired. 5. Provide adequate containment for fuel and oil products. 6. Ensure that all fuel, oil handling, storage and containment meet the requirements of BC Fire Code (1998) and A Field Guide to Fuel Handling, Transportation & Storage 3rd Edition, February 2002 (Ministry of Water, Land and Air Protection). 7. Ensure that any employees and/or contractors transferring fluids and fuelling equipment understand the environmental risks of the area, equipped with adequate spill prevention and response measures, have appropriate training, and are following fuelling practices deemed acceptable by BC Hydro. At a minimum, all refuelling activities must be conducted at least 15 m away from any water body. 8. Ensure that the operator is in attendance during all fuel transfers. 9. Locate emergency spill response kits in areas where oil filled equipment will be working and provide additional spill response materials in sufficient quantities on site to catch drips, minor leaks and spills (Suggested suppliers for this type of equipment and minimum spill kit contents are found in Appendixes C and D) NOTE: the spill response kits should only be used in the event of a spill incident and not for day to day equipment/tool management.

Clean-Up Technical assistance is available from Generation Sustainability on clean-up procedures and residue sampling. • All equipment and/or material used in clean-up (e.g. used sorbents, oil containment materials etc.) must be disposed of in accordance with BC Ministry of Water, Land and Air Protection (MWLAP) requirements. Generation Sustainability will assist in compliance with federal and provincial legislation. − Accidental spills may produce special wastes (e.g., material with > 3% oil) and contaminated soil. All waste disposal must comply with the BC Special Waste Regulations (BC Reg. 63/88) and the BC Waste Management Act ([RSBC 1996] Chapter 482). Compliance with these regulations generally requires: − Classification of the waste − Packaging requirements (proper labeling and suitable storage containers) − Transportation documentation − All transporters must be properly trained − Disposal in accordance with the regulations at an appropriate facility − Spill reporting requirements must also be followed Waste sorbent material may not be disposed of in a landfill without prior approval from MWLAP and the landfill operator. Contaminated soil must be treated and dealt with as required on a sitespecific basis and must comply with the requirements of the BC Contaminated Sites and Special Waste Regulations (B.C. Reg. 375/96). At a minimum, the contractor must consider soil relocation agreement standards and obtain soil relocation agreements as required. − − BC Hydro Page 32 Whatshan Water Use Plan Physical Works Terms of Reference 5 May, 2006 APPENDIX C - SPILL RESPONSE EQUIPMENT SUPPLIERS Please note: sorbent materials are designed for specific uses and purposes (e.g., oil only sorbents vs. general sorbents).
