5 1.0 INTRODUCTION This section of the Construction Environmental Management Plan (CEMP) describes the purpose of the CEMP, including a description of the Giscome Quarry and Lime Plant project (the Project). 1.1 Purpose of the Construction Environmental Management Plan This CEMP has been developed for the Project. The CEMP and appended component environmental management plans (EMPs) describe environmental mitigation measures to be carried out during the Project to avoid or minimize potential adverse effects to the environment. It is recognized that additional site-specific mitigation that arises through review of the Environmental Assessment Application, and as included in the Project s Table of Conditions and permit conditions, will be included in future iterations of this document. During the course of detailed design and construction, new information may also require updates to this plan. Therefore, this is a dynamic (i.e., living ) document intended to be updated as required to address new environmental protection and reporting procedures. The intent of the CEMP is to provide: A description of the role and responsibilities of all parties (Owner, Contractor, and Independent Environmental Monitor (IEM)) to ensure environmentally responsible construction practices, the mechanisms to achieve that goal, and methods the IEM uses to perform and report monitoring efforts; Environmental construction specifications to follow during the construction phase of the Project, and to include in construction contracts; and Component EMPs which have been developed for the Project. In addition to specific environmental construction specifications, the EMPs present a general framework for work standards and expectations. The EMPs contain relevant environmental laws and regulations, background information, and recommended Best Management Practices (BMPs) that will be used unless site-specific conditions allow a more effective approach. The CEMP applies to the construction phase of the Project. Once the Project is operational, environmental management and monitoring practices will transfer to the framework defined by the Operational Environmental Management Plan (OEMP) developed for the Project. The component EMPs will be appended to both the CEMP and OEMP, and apply to all phases of the Project. The component EMPs are also considered living documents and will be updated as appropriate during the life of the Project. 1.2 Project Description Graymont is proposing to construct and operate a limestone quarry and lime processing facility in the Giscome area of central British Columbia (the Project). Graymont is proposing to develop the Project in phases. The first phase will include quarry development and construction of the overland conveyor and the lime processing plant that will likely initially have one lime kiln. Second and third kilns will be added when market conditions support the additional volume. The rate of lime production will be approximately 200,000 tonnes per year with one kiln, with a potential annual lime production rate of 600,000 tonnes with three kilns. Conventional open-pit mining methods will be used to extract rock from the quarry. 1

6 The Project consists of the following major components: 1. Limestone quarry; 2. Conveyor and service road; 3. Electric transmission line connecting to the existing BC Hydro grid and related infrastructure; 4. Lime processing plant; 5. Product storage, loading, and shipping facilities; 6. Co-product storage and handling; 7. Limestone stockpiles; 8. Overburden and soil storage areas; 9. A rail spur; 10. Access roads; 11. Mobile equipment and fuel storage areas and facilities; 12. Maintenance, administration, and warehouse facilities; 13. Contact water collection ditches, settling ponds, and water management structures; 14. A non-contact water diversion ditch network and settling ponds; 15. Water supply facilities; 16. Sewage treatment and disposal facilities; 17. A limestone fines pile; and 18. An overburden pile. 1.3 Project Location The Project is located approximately 27km east-northeast of Prince George, BC. The proposed lime processing plant is located on Graymont-owned land, approximately 1km east-northeast of the settlement of Giscome (grid reference for approximate centre: E, N; Latitude 54 04'32.17" N, Longitude " W) on level terrain, immediately to the south of Eaglet Lake at an elevation of approximately 600m above sea level (asl). An adjacent CN rail line will be the main form of access to receive solid fuels, if required, and to ship lime offsite. Road access to the site will be along a currently existing road which connects to the south edge of the proposed plant area. The proposed quarry is located on Crown land, approximately 4km southeast of the settlement of Giscome (grid reference for approximate centre: E, N; Latitude: 54 03'07.02"N, Longitude '17.54"W). The topography in the vicinity of the proposed quarry is characterized by rolling hills separated by low-lying areas. Elevations are up to 855m asl in the hills to the northeast. The proposed limestone quarry is at an elevation of approximately 735m asl, and will be accessed by the Bateman Creek Road and an existing access road as well as via a new maintenance road which will parallel the proposed overland conveyor. Limestone will be transported to the processing plant by overland conveyor. 2

7 2.0 ENVIRONMENTAL MANAGEMENT PROCEDURES Environmental management during construction is a culmination of the mandatory statutes and regulations, standard industry BMPs, and project-specific mitigation measures identified throughout the Environmental Assessment Certificate Application. It is intended that all mitigation measures specified in the Application, will be reflected in the component-specific EMPs and/or environmental construction specifications outlined herein. 2.1 CEMP Structure EMPs present a general framework of work standards and expectations, as well as the specific mitigation measures determined for the Project. The CEMP is the over-arching guidance for how environmental considerations will be implemented and monitored during the construction phase of the Project. It is supported by numerous component EMPs appended to this CEMP, including: An Air Quality Management Plan (Appendix 1); A Water Quality Management Plan (Appendix 2); A Fish and Fish Habitat Management Plan (Appendix 3); A Soil Management Plan (Appendix 4); An Erosion and Sediment Control Plan (Appendix 5); A Wildlife Management Plan (Appendix 6); A Vegetation Management Plan (Appendix 7); A Petroleum Hydrocarbon Products, Ammonium Nitrate and Explosives Management Plan (Appendix 8); A Waste Management Plan (Appendix 9); A Heritage Resources Management Plan (Appendix 10); An Emergency Response Plan (Appendix 11); and A Traffic Management Plan (Appendix 12). Contractors will be expected to incorporate the content of relevant component EMPs into their site-specific work plans and practices for their given scope of work, as well as adhere to the environmental construction specifications outlined in Section 3.7. Three report templates are also appended to the CEMP: Weekly Independent Environmental Monitoring Report (Appendix 13); Environmental Incident Report (Appendix 14); and Work Stoppage Report (Appendix 15). 3.0 IMPLEMENTATION Key aspects of implementing the component EMPs appended to the CEMP include: Resources, roles, responsibilities and authorities; Training and awareness; Communication; Environmental monitoring; Documentation, including records, and document control; and Emergency preparedness and response. 3

8 3.1 Resources, Roles, Responsibilities and Authorities General roles of individuals with environmental responsibilities are described below, with further detail provided in other sections of the CEMP and appended EMPs. Owner: Graymont is the Owner of the Project and will ensure that the appropriate resources are available to establish, implement, maintain, and improve environmentally responsible construction practices. Resources provided by Graymont include environmental awareness and protection training, Qualified Professionals (QPs) or Qualified Environmental Professionals (QEPs) with specific expertise as needed, environmental documents specific to the Project (i.e., the CEMP) and financial resources. Construction Manager: The Construction Manager is responsible for overseeing the Contractor(s) and all related construction activities. The Construction Manager will also liaise with the Independent Environmental Monitor (IEM) about potential impacts to environmental components during construction. The Construction Manager will report to the Graymont Engineering, Procurement, and Construction Project Manager. The Construction Manager is expected to liaise with the IEM, and QEPs and QPs when needed. Contractor: The Contractor includes any company and its field staff retained by Graymont to design and construct a component of the Project. Contractor(s) will be responsible for implementing the CEMP during all phases of construction. The Contractor(s) will report directly or indirectly to the Construction Manager regarding all site activities. Independent Environmental Monitor: The IEM is responsible for ensuring compliance with the CEMP and other regulatory environmental commitments outlined in the Table of Conditions for an Environmental Assessment Certificate. Graymont will retain the IEM and the IEM will regularly report to relevant regulatory agencies on environmental issues encountered during construction. The IEM must identify, monitor, and promptly report any situations of ongoing or potential damage to the environment. The IEM will also advise of any unexpected situations encountered during construction that have potential impacts on environmental components. Qualified Environmental Professionals or Qualified Professionals: QEPs or QPs will have particular knowledge or expertise needed to advise and/or provide onsite support to Graymont, the Contractor, and the IEM, with respect to environmental or archaeological concerns on a specific element of the CEMP and associated EMPs. QEPs can be internal (i.e., Graymont employees) or external (i.e., consultants). Examples of QEPs or QPs include air quality specialists, archaeologists, and biologists. 3.2 Training and Awareness Prior to the construction phase of the Project, Graymont will arrange a construction start-up meeting or meetings with project Contractors, the IEM, and QEPs. The purpose of the meeting will be to clarify roles and responsibilities during construction, and to review general environmental, safety concerns and mitigation procedures. The Contractor is also responsible for ensuring that construction staff attend site-specific safety and environmental awareness orientation training prior to initiation of construction activities. The training will be repeated for new Contractor staff prior to beginning work at the site. 4

9 3.3 Communication Graymont will be responsible for communicating the construction schedule and timing of specific construction activities with regulatory agencies, as necessary. Communications will inform the local community and regulatory agencies of upcoming activities so they are aware. 3.4 Environmental Monitoring Environmental monitoring is conducted to ensure construction activities do not impact the environment. The IEM inspects for compliance with the environmental requirements of the Project. Findings will be recorded and reported to Graymont or other designates through which the monitor is contractually bound. The IEM is familiar with the regulatory and contractual requirements of the Project, and has the responsibility to report all non-compliant activities and stop work if necessary. As an unbiased, contractually-bound participant in the project, the IEM can quickly detect problem areas or potentially problematic events. Early detection equates to better control of environmental impacts and associated clean-up costs. To achieve the necessary site coverage and to allow for time off in accordance with WorkSafeBC requirements, multiple individuals may be necessary to fill the onsite IEM role. The IEM and any other designates will be appropriately qualified and experienced in environmental monitoring. However, it is anticipated that one lead designate will be contracted to oversee and administer the IEM process. This section provides an outline of the responsibilities of the IEM General Requirements 1. To inspect the construction work for compliance with the CEMP specifications, specifically: The project-specific mitigation measures found in Appendix 1 to 12; Environmental Construction Specifications (Section 3.7); All relevant federal, provincial, and municipal regulations (including adhering to work windows for fish and wildlife, and any permit conditions); and Construction practices described elsewhere in the CEMP (Section 3.7 Environmental Construction Specifications). 2. To identify and assess actual and potential conflicts between the construction activities and environmental features. 3. To identify, monitor, and promptly report any situations of ongoing or potential damage to the environment. 4. To recommend to the Construction Manager additional preventative and mitigation measures, should project activities have the potential to damage the environment. 5. To regularly provide Graymont and relevant regulatory agencies of environmental issues that arise during construction. It is intended that the Construction Manager will play a significant onsite role on an ongoing basis to ensure that environmental concerns are addressed in a timely and responsible manner. 5

10 3.4.2 Communications The following summarizes the specific communication requirements related to the IEM: 1. The IEM will report environmental concerns and the findings of environmental inspections to the Construction Manager and the appropriate regulatory agency as deemed necessary. 2. Graymont will notify the IEM of revisions or changes to the construction specifications or design, which may change the approach for environmental planning. 3. The IEM will approve the safety and environmental awareness orientation training for construction staff, and participate as necessary, before they begin construction activities and through regular briefings. 4. Environmental concerns identified by the Construction Manager are to be passed on to the IEM for resolution. 5. In the event of an environmental emergency, the IEM will follow the site-specific Emergency Response Plan (Appendix 11) Work Standards 1. The IEM will attend pre-construction meetings as necessary. 2. The IEM will provide onsite inspections as outlined in Section The IEM will inspect construction activities for compliance with the CEMP developed for the Project. The IEM will have the authority to stop work. 4. The IEM may be required to take soil or water samples, either as part of routine environmental monitoring activities, or as a result of an environmental emergency Environmental Monitor Inspection and Presence Onsite 1. The IEM will review and/or help mark off any sensitive areas in the proximity of construction activities in advance of the start of work. 2. The IEM will inspect the work for compliance with the CEMP developed for the Project, specifically: All Environmental Construction Specifications (Section 3.7); All proposed construction mitigation measures; All relevant federal, provincial, and municipal environmental regulations; and Any other aspects of the work which have the potential to impact the environment. 3. The frequency of inspections will depend on the activities underway onsite. The IEM will conduct random inspections during construction activities that have a potential for environmental impacts. 4. The IEM must monitor the duration of any work conducted instream and defined as work within the High Water Mark (HWM) of a watercourse or within 30m of the HWM. The IEM must also monitor the removal or decommissioning of sediment control measures. The IEM must be given advance warning if any of the aforementioned activities are scheduled. 5. Inspection/supervision will include all areas of the work site, including, but not limited to: The construction areas for environmental spills and non-compliance situations; In-stream or near-stream works; 6

11 Barriers separating the construction areas with areas not to be disturbed; The release of materials into watercourses or water bodies; Spill response supplies and equipment; and The fuel handling practices for compliance with Appendix 8 Petroleum Hydrocarbon Products, Ammonium Nitrate and Explosives Management Plan, of this report Non-compliance with Specifications 1. The IEM will immediately notify the Construction Manager after identifying any non-compliance situation. If the Construction Manager is not onsite at the time of the non-compliance situation, the IEM shall notify a named alternate to promptly rectify the situation. The IEM has the authority to stop work in the immediate area if: Construction activities unexpectedly and significantly affect the environment; An environmental emergency has occurred, or has the potential to occur, if activities continue unmodified; A regulatory agency has ordered the work stopped; or Water quality results exceed specified BC Water Quality Guidelines, or Canadian Council of Ministers of the Environment guidelines where BC guidelines do not exist. 2. If work is stopped, the IEM shall submit a Work Stoppage Report (Appendix 15) to document the occurrence. The report will include: Details of the events leading to the stoppage of work, including: date, time, location, personnel involved, and construction activities undertaken; Reference to the EMP, required mitigation measure, or environmental regulations that prompted the work to be stopped; Features of the environment that were of concern or at risk; The extent of environmental effect or damage incurred, if any; Details and analysis of any samples collected in conjunction with the stopped work; Remedial and due diligence actions undertaken by Graymont, IEM, other inspectors, and agencies (steps to prevent recurrence of the problem should also be outlined); The IEM and Graymont s actions and communications; Other site inspector s actions and communications; Contractor actions and communications; Agencies notified and their actions; Details of how issue(s) were resolved and steps taken to rectify the emergency; and A detailed photographic record of issue areas during and after the conditions have returned to normal activities. 3.5 Documentation This section describes the reporting requirements for the IEM during the construction phase of the Project. This will be updated to include reporting requirements to regulators that result from the Application review and permitting processes Reporting Requirements 1. The IEM will be responsible for documenting and maintaining a detailed record of all communication and correspondence with Graymont and QEP/QPs, including discussions, letters, and meetings. 7

12 2. The IEM will be responsible for documenting and maintaining a detailed record of all contact with regulatory agencies, including verbal, written, and meeting communication. 3. The IEM will be responsible for documenting and maintaining a detailed record of public contact including discussions, letters, and meetings regarding environmental issues. 4. The IEM will be responsible for developing and maintaining a detailed record of site visits. For each site inspection, the IEM will detail: date, time, location, weather conditions, inspection activities, construction activities observed, contacts made, recommendations, environmental issues, and required follow-up. Site visits will be documented in the Weekly IEM Report (a template is included as Appendix 13). 5. The IEM will be responsible for developing and maintaining a photographic record to document any mitigation measures, environmental emergencies, and stopped work. 6. The IEM shall submit a separate report if an environmental incident occurs and if work is stopped. Templates for an Environmental Incident Report and a Work Stoppage Report are included as Appendix 14 and 15, respectively. 7. The weekly IEM report will include: General progress of the project with respect to any work in ESAs (e.g., near-water works); Routine mitigation measures being used, and monitoring of mitigation effectiveness; and Environmental concerns encountered, recommendations made, and new mitigation measures taken, if any, including a list and record of all parties notified of any changes. 3.6 Emergency Preparedness and Response In spite of the measures that are put in place to protect the environment, it is recognized that there is potential for incidents and malfunctions to occur during construction. As a result of an accident or malfunction, a release to the environment could occur, and would have the potential to affect air, water, and soil quality, vegetation, and/or fish and wildlife species and their habitat, as well as cause injury or death to site personnel. Graymont is committed to safeguarding the health and safety of its employees, contractors, the public, and the environment. In the event of an accident, malfunction and/or emergency, the Emergency Response Plan (ERP) Appendix 11 will be implemented. Key components of the ERP include: Emergency contacts; Roles and responsibilities in the event of an emergency; Fire prevention and response; Spill prevention and response; and Document control and reporting. 8

13 A number of other EMPs appended to this CEMP also outline measures relevant to emergency prevention. In particular this includes: A Vegetation Management Plan (Appendix 7) for the prevention of fires started by construction activities; An Erosion and Sediment Control Plan (Appendix 5) for the prevention of sediment releases into water sources; A Petroleum Hydrocarbon Products, Ammonium Nitrate and Explosives Management Plan (Appendix 8) and Waste Management Plan (Appendix 9) for the prevention of spills into the receiving environment; and A Traffic Management Plan (Appendix 12) for the prevention of traffic-related accidents. 3.7 Environmental Construction Specifications This section of the CEMP contains the environmental construction specifications to follow during the construction phase of the Project. Section 3.7 in its entirety, will be included in the Technical Specifications for each construction contract. The environmental specifications will therefore become part of the contract document. Should the need for additional environmental construction specifications become apparent for certain construction phases, these will be submitted as amendments to the CEMP for approval from the Ministry of Energy and Mines or other regulators, as needed. The environmental construction specifications are the minimum requirements expected to be met by the Contractor during the construction phase of the Project. The Contractor is also expected to review and comply with the various EMPs appended to this CEMP. The various EMPs developed for the Project provide relevant context, background information, and project-specific mitigation measures developed for the Project. Table 1 below provides an overview of environmental considerations by project activity. It cross-references the EMPs appended to this CEMP by project activity (e.g., clearing, grading, road construction, crushing, and stockpiling). The intent of this table is to provide contractors with a user-friendly reference to EMPs that are relevant to their activity or scope of work. 9

The Contractor shall acquire all other permits, licences, and approvals, including costs related thereto. Permits, licences, and approvals to be acquired by the Contractor may include, but are not limited to, the following: Waste Management Permit and Approvals (Hazardous Waste Regulations) (Waste Management Act, BC). The Contractor shall, as required for the proposed construction methods or in the event of a spill or environmental emergency ensure that all hazardous waste is managed and disposed of by an authorized hazardous waste management company; and Graymont or its Contractor is responsible for ensuring all waste generated during construction is disposed of or recycled at an authorized facility Construction Timing 1. No work will be conducted in the wetted perimeter of fish-bearing watercourses or watercourses with unknown fish presence, except during the approved instream works window for the Omineca region unless authorized to do so by the appropriate regulatory agencies. Species Construction Activity Reduced Risk Window Rainbow Trout Instream work July 15 April Clearing will occur within the least-risk window for nesting birds in the Omineca Region whenever possible (August 1 through to April 30). If clearing must occur outside of the least-risk window, it must be completed in accordance with the environmental construction specifications for clearing outlined below Spill Contingency and Response Plan 1. The Contractor will adhere to Graymont s ERP (Appendix 11). Prior to construction, Graymont will review the ERP with the Contractor. 2. The Contractor will provide, at all times, readily-accessible onsite spill response materials, such as containment booms, absorbent sweeps, and pads. 3. The Contractor will periodically review the Spill Contingency and Response Plan for appropriateness, and will ensure that all required response materials are onsite in adequate supply, and workers, including subcontractors, are familiar with the requirements of the Spill Contingency and Response Plan. 4. In the event of a spill or emergency, the site will be restored to the current Waste Management Standards. Any waste and clean-up materials, equipment, and goods, including soils and water deemed to be contaminated by the Ministry of Environment or Environment Canada will be removed and disposed of offsite Clearing 1. Prior to any site clearing activities, raptor nest surveys will be conducted by a QEP. Should any raptor nests be observed, the Contractor (under the direction of the QEP) will follow the BMP guidelines presented in BMPs for Raptor Conservation during Urban and Rural Land Development in British Columbia. Should any raptor nests be found, the IEM and a QEP will provide advice on how and when to proceed with clearing. 12

17 2. If clearing activities are scheduled outside of the least-risk window for nesting birds in the Omineca Region (August 1 through to April 30), an active nesting bird survey of the area to be cleared must be completed by a QEP. This inspection must be undertaken immediately prior to clearing activities (i.e., clearing must be initiated within 24 hours of the survey). Due to nesting activity, some areas may have to be cleared at a later date, as specified by the QEP. 3. The Contractor must implement erosion and sediment control measures in accordance with relevant guidance outlined in the Erosion and Sediment Control Plan (Appended to the CEMP) and to the satisfaction of the IEM, prior to any clearing activity. 4. Prior to clearing, the Contractor will mark off the construction and clearing areas with highly-visible fencing, flagging tape, or markers. 5. Clearing will be kept to a minimum. 6. Hand clearing will be carried out on the banks of any watercourse, on all ground that has a slope in excess of 30% (see exception below), and in any area where the IEM directs. 7. Machine clearing will be carried out on all ground that has a slope of 30% or less where hand clearing does not apply. Ground that has a slope of greater than 30% may be cleared by machines with extended reach, provided that the wheels and tracks of the machine can be located on ground with less than 30% slope. 8. Trees will be felled away from watercourses and standing timber. 9. With the exception of merchantable timber and woody debris intended for future reclamation use, cleared debris shall be disposed of offsite or within the boundaries of the property (with consideration of forest health restrictions and fire risk management) as described by the Wildlife Management Plan and Waste Management Plan (Appended to the CEMP). 10. Fuel will be managed in accordance with the Petroleum Hydrocarbon Products, Ammonium Nitrate and Explosives Management Plan (Appended to the CEMP). 11. Storage, handling, fuelling and equipment maintenance and repair sites will be located on flat, stable ground, away from environmentally sensitive areas such as wetlands and riparian areas. 12. Fuel storage tanks will comply with Aboveground Storage Tank Regulations. 13. The Contractor will provide sufficient drums to drain the tank if necessary. 14. The Contractor will conduct daily inspections of the fuel storage facility for leaks and spills, and will maintain the facility to Fuel Handling Transportation and Storage Guidelines. 15. Accumulated rainwater will be drained from the containment berm on a regular basis. 16. The Contractor will inspect all construction equipment for leaks or worn hoses or fittings prior to site access and on a regular basis during construction. Leaks will be fixed prior to continued use onsite. 17. No petroleum products, including fuel and oil, will be disposed of on the site. Waste oil will be contained and stored in approved containers onsite and disposed of offsite regularly. 18. No equipment refuelling or servicing will be undertaken within 30m from any watercourse, waterbody or surface water drainage. 19. The Contractor will remove all used and unused fuel and oil, storage facilities, and any associated contaminated soils prior to completion of work. 13

18 3.7.6 Materials Storage and Disposal 1. Organic debris and topsoil from the quarry will be stockpiled in the designated Topsoil Stockpile area, which will be a minimum of 15m away from the HWM of any watercourse. Organic debris and topsoil will be used during site reclamation/revegetation whenever possible. 2. Stored material will be graded to ensure proper drainage during storage. 3. The Contractor will secure permits for and manage, store, remove, and dispose offsite all waste generated at the site, including construction, spill response, household, and sewage wastes. 4. The Contractor will store construction waste in a designated spoil area or within the boundaries of Graymont s property as directed by the IEM. All waste and unused materials will be removed from the site prior to the completion of the work Burning The Contractor will not burn waste onsite, including wood and debris generated during land clearing Concrete 1. Pre-cast concrete structures will be used where feasible. The Contractor must avoid directly or indirectly exposing concrete, cement, mortars into any waterbody. 2. A carbon dioxide (CO2) tank with regulator, hose, and gas diffuser will be readily available during concrete work within 30m of any waterbody, if reasonable to implement. The tank will be used to release carbon dioxide gas into an affected area to neutralize ph levels should a spill occur. Workers will be trained how to use the tank. 3. Any water that contacts uncured or partly cured concrete during activities like exposed aggregate wash-off, wet curing, or equipment washing will be prevented from directly or indirectly entering any waterbody; 4. Complete isolation of cast-in-place concrete and grouting from fish-bearing waters will be maintained for a minimum of 48 hours if the ambient air temperature is above 0 C (for the entire period) and for a minimum of 72 hours if ambient air temperature is below 0 C. 5. Any water that contacts uncured or partly cured concrete will be isolated and held until the ph is between 6.5 and 9.0 ph units, and the turbidity is less than 25 NTU measured to an accuracy of +/-2 NTU Erosion and Sediment Control 1. Erosion and sediment control measures will be in place before any clearing activity. 2. The Contractor will be responsible for the continued effectiveness, maintenance, and stability of erosion control devices. These devices will be monitored regularly by the IEM. 3. The Contractor will stop construction and vehicle activity during excessively heavy periods of precipitation when the potential for erosion is unacceptably high. The IEM will advise the Contractor if these conditions are occurring. 4. Disturbed areas will be revegetated with species native to the area as soon as possible to minimize the potential for soil erosion. 14

19 5. Where possible, soil disturbance in areas with moderate to high erosion potential will be confined to periods of dry weather. Appropriate equipment will be selected and traffic will be limited through these areas to minimize disturbance. 6. Existing vegetation will be kept intact whenever possible to provide erosion control, sediment management, and a source for local seed. 7. Steepness and/or length of slopes will be minimized whenever possible, in sloped areas being disturbed. 8. During construction, temporary erosion and sediment control measures (e.g., silt fencing) will be installed properly and where appropriate for immediate protection of water quality from sediment in stormwater runoff Instream Work 1. The QEP will monitor instream works and conduct water quality monitoring as per the Water Quality Management Plan (Appendix 2); 2. Watercourse crossings will be constructed in isolated work areas by erecting temporary barriers upstream and downstream, and diverting flow around the work area. 3. Water will be diverted around isolated work areas using submersible pumps (or equivalent) to maintain flows to downstream habitats and to prevent fish stranding. 4. Aquatic life will be salvaged 1 from isolated work areas prior to de-watering. 5. Sediment-laden flows will be pumped into vegetation for filtration (if required). 6. Fish screens will be fitted to pump intakes, to prevent fish entrainment Reclamation 1. The Contractor will restore all work areas at the site to pre-construction status as much as possible. This will include removal of equipment, wastes, construction materials, fencing, boundary markings, construction mitigation facilities, etc. prior to completion of the work. 2. The Contractor will grade and contour any disturbed areas to promote drainage and conform to adjacent topography prior to completion of the work.
