FIRST NATIONS ENGAGEMENTIn making decisions on authorizations, the government will be fulfilling its responsibility to consult, and where appropriate,accommodate First Nations. The government takes this responsibility seriously and encourages the applicant to engage First Nationsearly and often as part of any planned development.

Establishing good relations with First Nations who might be affected by a proposed development is a key part of any successful miningoperation. The Ministry of Energy and Mines encourages applicants to engage and information share with First Nations that might beaffected by a proposed development prior to submitting an application. The earlier in the life of a proposed activity that the avenues ofcommunication are established the greater the likelihood that the relationships formed will be constructive and beneficial to all parties.A lack of information sharing and engagement by the applicant may result in extended timeframes for decision.

Applicants should keep a detailed record of information sharing and engagement with First Nations on their project in the event thegovernment needs to review it. Information on First Nations information sharing and engagement should include the following: a list ofFirst Nations contacted, whether the activity was modified based on feedback from First Nations, and whether the applicant has enteredinto any informal or formal agreements with First Nations in connection with the project.

Site C Clean Energy Project Mines Act Notice of Work - Highway 29, Halfway River Materials Sources

Management Plan

1. INTRODUCTION

Highway 29 is two-lane rural arterial undivided highway under the jurisdiction of the British Columbia Ministry of Transportation and Infrastructure (MoTI) that connects Hudson’s Hope to Fort St. John. It runs along the north side of the Peace River. Segments of the highway will be inundated or rendered unstable by the Site C reservoir, resulting in the need to realign approximately 30 km of existing highway at Lynx Creek, Dry Creek, Farrell Creek, Halfway River, and Cache Creek. Construction of the Halfway River segment, including a new bridge over Halfway River, is planned to commence in fall 2019 and be complete by the end of 2022.

Embankment and road base material for the construction of the Halfway River realignment will be required and is planned to be excavated primarily from a future inundated area. The application area for the materials source will be between the existing highway and the Peace River, along the Halfway River, and above the existing highway as shown on Dwg No. 1016_N11_00471-1 and 1016_N11_00471-2.

The purpose of this document is to support BC Hydro’s Mines Act Notice of Work application for the Halfway River Inundated Materials Source. This document provides information on existing environmental conditions within the requested Notice of Work area, proposed activities and works, schedule of work, access and equipment, and future use of the area. Additional applications will be submitted under separate cover to support the construction of the realigned Halfway River section of Highway 29. These include:

Land Act Licence of Occupation for Halfway River Inundated Materials Source

Water Sustainability Act Application for Short Term Use of Water (WSA s.10)

Water Sustainability Act Applications for Changes In and About a Stream (WSA s.11)

Land Act Licence of Occupation for clearing and construction (issued January 2019)

Forest Act Occupant Licence to Cut (issued January 2019)

2. EXISTING CONDITIONS

The source area is comprised of a river terrace and point bar feature along the west side of the Halfway River, immediately north of and adjacent to the existing Highway 29 alignment, The planned new alignment for Highway 29 traverses the approximate center of the source area (Area A) in a generally southwest to northeasterly direction. The area will ultimately be inundated by the Site C reservoir. The overall surface of the area is generally flat to gently undulating, ranging in elevation from approximately 434 m to 438 m. The lower elevations were proximal to the edges of the Halfway River channel and related seasonal flood channels that bisect the areas from northwest to southeast. The higher elevations are associated with a terrace area that comprises the approximate southwestern half of the site. The area was cleared and grubbed in winter 2019 in preparation for construction activities.

Test pits were dug throughout the proposed gravel extraction area to determine the extent of the gravel deposits and the gravel properties. Drill holes were also completed along the proposed alignment. The test pits and drilling confirmed the presence of undulating shale

bedrock underlying the site at depths ranging from approximately 6 to 8 m, depending on location. This corresponds to an approximate elevation range of 427 m to 431 m. Ground water was encountered within most of the test pits and all the drill holes. The depth to groundwater varied by location and the time of investigation. Generally, during the April-May 2017 investigation the groundwater was encountered at elevation 432.6 m to 434.2 m. In January 2018 the groundwater was encountered slightly lower, at elevation 431.8 to 433.5 m. In Area A-1, which is planned as the major excavation area, the thickness of the granular material encountered in the test pits ranged from 1.2 to 4.9m (average 2.8 m); however, all the test pits terminated in gravel and the gravel likely extends to depths encountered by the alignment drilling. The maximum depth of exploration was limited by the groundwater table which was encountered in most of the test pits.

Existing baseline conditions are further described in the Fish and Fish Habitat, Vegetation and Ecological Communities, Wildlife Resources and Heritage Resources, are described in the Site C Project’s EIS Volume 2 Sections 12, 13 and 14, and Volume 4 Section 32, respectively.

Activities related to the realignment of Highway 29 at Halfway River may affect bear dens, beaver lodges/bank dens and rare plant occurrences. As outlined in the Site C Project’s Construction Environmental Management Plan1 (CEMP), any active bear den will be buffered by 200 m. The buffer will be retained until the den is no longer occupied. Beaver dens/dams will be removed as required as per the conditions laid out in Wildlife Act Permit FJ14-1540052 and the Water Sustainability Act Notification 9000138. Mitigation for the loss of rare plant occurrences is described in the Site C Vegetation and Wildlife Mitigation and Monitoring Plan V1, June 5, 2015.3

3. DESCRIPTION OF WORK

Highway 29 realignment at Halfway River will require relocation of a 3.7 kilometer section of highway and include the construction of river crossing. MoTI will be tendering and managing the construction contract for the relocation and bridge. Gravel and borrow material is required for the contract including embankment construction over the length of the project.

The inundated material source would supply the highway and bridge projects with gravel and borrow material as well as provide the contractors an area for their operations. This area would also be used for stockpiling of material and waste disposal and may be used for staging and a temporary work camp.

The Halfway River inundated materials source areas have been cleared during the February/March 2019 under a separate tenure. The highway construction contractor is anticipated to arrive on site in fall 2019 after the clearing is complete. The construction contractor’s first activities will be stripping the areas that will be mined. The stripping material will be stockpiled within the site limits and used for progressive reclamation. The highway contractor will primarily source material from the designated borrow area, but may utilize the stockpile area, contractor area, or waste area if required. Screening and/or crushing may begin in fall 2019. Some crushed material will be stockpiled for use as pavement and crush gravel. The contractor will also need to screen or crush the pit run to meet a specified gradation for

embankment purposes. The crushing and screening operations will include excavators, loaders, trucks and a crushing or screening plant. The location of the crushing operation will be determined by the contractor. The material will also be tested on site to ensure it meets specifications. The processed granular material will then be loaded and hauled to the construction site using trucks. A new access road to the borrow area will be constructed within the permit boundary.

A contractor area within the permit application boundary will be designated for use as a laydown or staging site. The contractor may utilize this location for a small temporary worker camp. If the contractor plans a camp at this location all relevant permits will be applied for and in place prior to its establishment. As part of the Highway 29 re-alignment at Halfway River, in order to provide a cost-effective and reliable concrete supply for construction, there is potential to establish a batch concrete plant on-site. See Appendix A - technical memo titled “Site C Clearing Energy Project – Road and Bridge Infrastructure (Highway 29) Halfway River Concrete Batch Plant Specifications” and Appendix B - Pit Development Plan R3-329-601 for further details and proposed layout. These Plans serve to outline the general technical specifications (including plant footprint and servicing requirements) for the potential concrete batch plant and pit layout. Site specific requirements will ultimately be determined by the chosen contractor.

All operations will be in accordance with the applicable MoTI Standard Construction Specification 165 (SS165)4, the Mines Act, and the Health, Safety, and Reclamation code5.

4. SCHEDULE OF PROPOSED WORK

Site preparation in the Halfway River area started in February 2019 with clearing and grubbing of commercial and non-commercial vegetation. Construction is expected to commence for the Halfway River segment in fall 2019 and is scheduled to be completed by fall 2022.

Mining for gravel and borrow for the highway realignment at Halfway River would commence in fall 2019 and may be required until 2023. Material from the borrow area will primarily be used for construction at Halfway River, but may also be required for other Project needs.

A detailed schedule will be developed closer to the start of works. All works will begin only on receipt of relevant permits and approvals.

5. ACCESS AND EQUIPMENT

Access to the site will generally be from Highway 29 and the contractor will determine the location of internal roads including access to the material source

Access to the Halfway River construction site will be gated and locked when the construction site, including the area to be mined, is active.

All access roads within the Halfway River site boundary will be considered temporary as this area will ultimately be inundated by the Site C reservoir.

Disturbed areas will be stabilized following the completion of field investigations in a manner that complies with the MoTI Standard Construction Specification 165 (SS165), Site C CEMP and the Contractor’s Environmental Protection Plan (EPP).

In the period between extraction and inundation, the extraction areas will be progressively reclaimed. The scope of reclamation works is anticipated to include slope stability, placement of stripping and overburden as a growing medium, and seeding and preventative measures for invasive plants and noxious weeds. Progressive restoration will be undertaken as the areas are mined. Progressive reclamation will be in accordance with the Mines Health, Safety, and Reclamation code; MoTI SS165, and the Site C CEMP. The highway contractor will provide a progressive reclamation plan.

7. ENVIRONMENTAL MANAGEMENT AND MONITORING

In the following sub-sections, component measures are described, followed by a description of general approaches to environmental management. An environmental protection plan (EPP) will be prepared by the highway contractor ahead of development described herein. The EPP will be required to meet MoTI and Site C CEMP requirements and hence will provide a description of site-specific measures to be implemented. Works will not begin until MoTI and BC Hydro accept the contractor’s EPP.

Air Quality

Air quality control, including dust and silica, will be completed under an approved EPP implemented by the highway contractor in accordance with MoTI SS165 and the Site C CEMP requirements. Air quality management may include control of emissions of fine particulate matter, pollution prevention, temporary barriers and smoke management.

Noise

Noise monitoring and mitigation will be completed under an approved EPP implemented by the highway contractor in accordance with BC MoTI SS165 and the Site C CEMP requirements.

Materials Management

A waste disposal area has been designated for the highway and bridge contractor. Unsuitable material will be stockpiled and capped with 0.6m pit run upon completion of the highway works and prior to inundation. Potential Acid Generating (PAG) rock may be encountered during the highway and bridge pile excavation. PAG rock will be disposed of in an engineered and controlled manner in accordance with the “Potential Acid Generating Rock Controlled Disposal”, see Appendix C. The contractor will provide a disposal plan for PAG in accordance with these provisions.

General Guidance on Management and Monitoring



2019-04-29 Page 5 of 5

Environmental management will comply with the MoTI’s SS165 “Protection of the Environment” and the Site C Project’s CEMP.

An archaeological overview assessment has been completed for the entire highway footprint and material source area and any archaeological resources identified from sites will be recovered before construction begins. The contractor will follow chance find procedures if additional artifacts are discovered during construction. Work in the area will be stopped until recovery is completed.

8. FUTURE USE

The newly aligned highway will be permanent. Access roads, laydown areas, and borrow sites will be reclaimed in accordance with the EPP, Site C CEMP and MoTI’s SS165. The material source locations at Halfway River will be permanently under water when the reservoir is full.

Subject: Site C Clean Energy Project – Road and Bridge Infrastructure (Highway 29) Halfway River Concrete Batch Plant Specifications

1.0 INTRODUCTION

As part of the Highway 29 re-alignment at Halfway River (associated with the Site C Clean Energy Project), in order to provide a cost-effective and reliable concrete supply for construction, there is potential to establish a batch concrete plant on-site at Halfway River. To support permitting, this memorandum serves to outline the general technical specifications (including plant footprint and servicing requirements) for the potential concrete batch plant.

3.0 DISCUSSION

The 50% Detailed Design for the Halfway River bridge includes a Pit Development Plan that provides a potential location for a concrete plant (as well as an aggregate crusher and asphalt plant). The proposed location for the Halfway River Pit is on the west bank of the river, northwest of the existing Highway 29 Halfway River bridge, as shown on Drawing R3-329-601 (attached to this memo). The concrete volumes required for the Halfway River bridge (per the 50% Detailed Design) are as shown on the adjacent table. In total, the project will require approximately 15,000 m3 of concrete for construction. Concrete batch plants range in capacity (low to high), complexity (manual to full automated batching), and mobility (portable to stationary), and are available for either dry transit mix or wet central mix concrete. As the current plan

is to install the batch plant at the proposed Halfway River Pit, and the concrete requirements for bridge construction, the following assumptions have been made regarding selection of a batch plant for Halfway River: Capacity

On the low-end of capacity, small, highly-transportable and mobile concrete batch plants can produce wet concrete in the range of 10 to 50 m3 per hour, with individual concrete batch sizes less than 0.5 m3 for the smallest plants. On the high-end, large, stationary concrete batch plants can produce wet concrete in the range of 200 to 250 m3

per hour, with individual concrete batch sizes over 12 m3 for the largest plants. The Halfway River bridge requires a significant volume of concrete for construction and capacity will likely be the primary criteria in selecting an appropriate batch plant for the project. For critical concrete pours for bridge elements (and especially the deck pours), a high hourly output of concrete will be necessary. It is estimated that the potential batch plant will therefore require an output capacity upwards of 100 m3 per hour. Mobility

Some construction projects, such as concrete paving, use highly mobile batch plants, positioning the plant as close as possible to the concrete placement and relocating the plant as work progresses. With size being an obvious limiting factor in a plant’s mobility and transportability, concrete productivity is limited for mobile batch plants and the highest output concrete plants will be stationary. As noted above, capacity is likely to be the primary factor in selecting an appropriate plant for Halfway River which would likely eliminate most small, mobile facilities. Further, there is no project requirement for the batch plant at Halfway River to be mobile, with the proposed Halfway River Pit plant location intended for the duration of the work. Note that mobile batch plants need not be completed excluded, however, as there are those available that may meet capacity requirements. Automation

Automation of batching generally goes hand-in-hand with plant capacity. Small concrete batch plants may not have any automation; measuring of aggregate, cement, etc. for batching is completed manually. While the high-output, larger plants will be fully automated. In consideration of the volume of concrete required for Halfway River, and in view of the concrete mix requirements necessary for bridge construction, fully-automated batching is expected to be necessary for Halfway River. Transit vs. Central Mix

The difference between transit and central mix batch plants are where the concrete ingredients are mixed. Transit mix batch plants will load all the concrete ingredients into the concrete truck, with the truck itself acting as the concrete mixer i.e. truck mixer. Central mix batch plants mix the concrete at a stationary mixer before loading to trucks, i.e. a plant mixer. Transit mix allows for some of the mixing to take place during travel to site which may be an advantage, but transit mix can result in inconsistent concrete quality across truck loads and as well as being hard on the truck drums. Central mix batch plants are more expensive and may be harder to maintain, however, their advantage is consistent concrete quality across truck loads as well as higher production rates. When reviewing manufacturer’s products, transit mix batch plants are simply the base model of batch plant and can be upgraded to a central mix batch plant by adding on a plant mixer. The proposed Halfway River Pit plant location means there will be a relatively short distance for concrete to travel to site and there is therefore little advantage to mixing concrete in transit. Further, the quality requirements for bridge



construction may necessitate central mixing. It is therefore expected that a central mix batch plant will be required for Halfway River.

Appendix C

Appendix C: Potential Acid Generating Rock Controlled Disposal

i) Disposal of Excavated Rock

Rock excavated from the pile rock sockets is Potential Acid Generating rock and will be disposed at the designated disposal site within 5 days of its excavation. The excavated rock will have to be managed for the construction period and disposed of permanently at the designated disposal site. The temporary storage location and the permanent storage location may be the same but any other PAG disposal site must not be disturbed. The Contractor will design and maintain the disposal site for the excavated rock, including perimeter drainage works to keep the excavated rock dry from surface drainage, and maintain a temporary membrane over the rock to keep the rock dry from precipitation and not in contact with the atmosphere. The storage design for the temporary condition shall, at a minimum, include the following:

(a) The disposal location for the PAG rock must be stripped clear of any organic rich surface soils.

(b) The disposal site shall be underlain by a low permeability clay or clay/silt liner with a minimum thickness of 0.3m of clay or clay/silt with a fines content greater than 50% that has been placed and compacted to the compaction specifications of BC Ministry of Transportation and Infrastructure Standard Specification (SS) 201.37 in at least two lifts. The clay or clay silt liner must cover the site to the ditch in all directions and be graded toward the ditch in all directions at a minimum of 2%.

(c) The Contractor will construct and maintain for the duration of the Work a perimeter V-shaped ditch at least 1.0m deep and berm. The ditch will outlet while maintaining a minimum of 0.2m of water in the ditch when drainage is occurring. The ditch grade will have to be designed and constructed so that it does not erode. The ditch must include an outer berm designed to divert surface drainage around the site, or from entering the ditch.

(d) The excavated rock will be placed a minimum of 2m from the ditch edge but the permanent condition may require a greater distance to allow for a final clay or clay/silt cover depending on the sampling system designed.

(e) The excavated rock may be placed at a maximum slope of 2H:1V.

(f) Not later than 1 day following placement at any location all excavated rock at that location will be covered with an impermeable membrane.

(g) The membrane will be low density polyethylene such as Enviroflex 20 mil or approved equivalent. Any approved equivalent must have a design life of at least 2 years.

(h) Any plateau surface of the pile will be graded in a manner that maintains surface drainage off the membrane away from adjacent uncovered newly placed rock.

(i) The membrane may be overlapped at the top of a pile. The membrane may be overlapped on the sides of a pile provided 2m of overlap is used and graded in a manner to flow away from the overlap.

(j) The membrane must be weighted down with sand bags or equivalent to protect from wind. Piercing the membrane with anchors is not acceptable.

(k) The membrane must cover the excavated rock and end at an elevation lower than the adjacent rock so that water flows off the membrane into the ditch, without contacting the rock.

(l) Any breach of the membrane must be repaired by the Contractor within 12 hours of discovery.

(m) For the duration of the contract the Contractor must sample the water discharged from the perimeter ditch monthly and provide the results to the Ministry Representative within one week of the test results being available. Water discharged from the location of the PAG disposal site must meet the water quality requirements of the CEMP.

The permanent storage shall, at a minimum, include the following:

(n) In all directions the excavated rock pile will be graded with positive drainage away from the pile and towards the ditch at a slope of greater than 2 %.

(o) The Contractor will construct and maintain for the duration of the Work a perimeter V-shaped ditch or perforated pipe sampling system at least 1.0m deep. The ditch will outlet to the drainage system while maintaining a minimum of 0.2m of water in the ditch when drainage is occurring. The ditch grade will have to be designed and constructed so that it does not erode. The Contractor may maintain the ditch as a water quality sampling location or may maintain a perforated pipe system or alternate collections system to allow long-term water quality sampling.

(p) The excavated PAG rock will be placed below elevation 456m.

(q) The final excavated PAG rock storage pile will be covered at the top and sides with a minimum thickness of 2.0m of clay or clay/silt with a fines content greater than 50% that has been placed and compacted to the compaction specifications of SS 201.37. The clay or clay/silt cover may not be placed in freezing conditions or during rain.

(r) The membrane may not be left in place in the permanent condition. The excavated rock may not be left exposed to the atmosphere or to precipitation for more than 5 days without either the membrane or the clay or clay/silt cover of at least 2.0m thickness.

(s) In all directions the clay or clay/silt cover will be graded with positive drainage away from the pile and towards the ditch at a slope of greater than 2% but less than 20%. The top of the clay must be lower than elevation 458m. If the clay or clay/silt covers the former ditch location a perforated pipe, or alternative system, must be maintained for long-term water quality sampling.

(t) The surface of the clay or clay/silt cover will be covered with a 450 mm thick layer of gravel placed without compaction other than by placement.

(u) For the duration of the contract the Contractor must sample the water discharged from the perimeter ditch monthly and provide the results to the Ministry Representative within one week of the test results being available. Water discharged from the location of the PAG disposal site must meet the water quality requirements of the CEMP.
