1 INTRODUCTION

1.1 Project Description Integrated Sustainability was retained by the Sunshine Coast Regional District (SCRD) to complete an environmental scoping assessment to support Phase 3 of the raw water reservoir project (the Project), which comprises a feasibility study of potential reservoir sites. Integrated Sustainability previously completed Phases 1 and 2 of the Project in March 2019. Details on the scope and work, results, and conclusions from Phases 1 and 2 of the Project can be found within the Phases 1 and 2 Feasibility Study Report (Integrated Sustainability 2019a).

1.2 Objectives The objectives of Phases 1 and 2 of the Project were to identify and evaluate potential sites for a raw water reservoir and develop conceptual designs and comparative costs for sites deemed feasible for a reservoir with capacity to meet the current and future water demands to supply to the existing Chapman Water System (Integrated Sustainability 2019a). Four sites (the Sites) were selected to advance to Phase 3 of the Project following initial site identification and desktop screening (Site A, Site B, Site C3, and Site C4). See Figure 1 for locations of the Sites.

The environmental scoping assessment of Phase 3 includes a desktop review and risk evaluation to identify key features that may impact design criteria or site selection and development of an environmental scope of work for the remainder of the Project. Integrated Sustainability has prepared this report to support the Project through:

Review of existing baseline environmental data reports (if available) and desktop study conducted during Phases 1 and 2 of the Project (Integrated Sustainability 2018 & 2019b)

Evaluation of the potential environmental risks and areas of concern for each of the Sites

Development of a scope of work for collection of additional data (desktop and

field) and required investigations to support regulatory applications

This report does not cover the environmental scoping for supporting infrastructure for the Sites (i.e. Creek point of diversion, water conveyance pipelines, and access roads)

This report does not detail the required permits and timelines for each of the Sites, please refer to the Regulatory Roadmap (Integrated Sustainability 2019c)

2 METHODS The desktop scoping assessment and risk evaluation were completed using available resources including:

Page 6: Raw Water Reservoir Feasibility Study - SCRD

VP19-SCR-01-00-RPT-EN-Enviromental-Assessment-Rev1.docx 28 October 2019 | Page 2

Application Analysis Tool through the BC Application Management System (AMS) (OGC 2019)

BC Water Resources Atlas (GoBC 2019)

Bill 51 – Environmental Assessment Act (Legislative Assembly of British Columbia 2018)

Groundwater Review Assistant (BC OGC 2019a)

iMap BC (GoBC 2019b)

Habitat Wizard (GoBC 2019c)

Northeast Water Tool (NEWT) (BC OGC 2019b)

Mapped environmental considerations in relation to the Sites are shown on Figures 2 to 5.

3 RESULTS

3.1 Desktop Review Sites A and B are located near the existing Chapman Water System infrastructure and the Sunshine Coast communities (2 kilometers (km) to 3 km). Sites C3 and C4 are located further from and northeast of the Sunshine Coast communities (10 km to 15 km) and are situated within existing subalpine lake basins. The following information summarizes findings from the current desktop review and previous Integrated Sustainability desktop reports (Integrated Sustainability 2018 & 2019b). A detailed table showing Environmental Criteria is provided in the Raw Water Reservoir Feasibility Study (Integrated Sustainability 2019a).

The Groundwater Data Report was reviewed for the Sites and there were no Oil and Gas Activities Act (OGAA) wells or surface water records in the vicinity (5 km) of the Sites (GoBC 2019a).

A review of water well records on iMap BC Environmental Monitoring Stations showed 18 monitoring wells within 5 km of Sites A and B whereas Sites C3 and C4 do not have any monitoring wells identified within 5 km.

The British Columbia (BC) Habitat Wizard was reviewed and none of the Sites fall within the Old Growth Management Areas (GoBC 2019c).

None of the Sites are located within Tetrahedron Provincial Park; however, Sites C3 and C4 are located within proximity (100 m to 300 m) of the park boundary.

All Sites contain one or more Provincial Species of Concern. Sites A and B both contain one or more Provincial Species at Risk; however, Sites C3 and C4 have none identified. Table 1 in the Detailed Desktop Assessment (Integrated Sustainability 2019b) provides a detailed list of species identified. Upon completion of the field investigation, all species identified in the field by a Qualified Environmental Professional (QEP) will be provided in the field report.

Existing water bodies are located within the footprints of Sites C3 and C4; however, no documented fish presence has been recorded within the existing water bodies at

Page 7: Raw Water Reservoir Feasibility Study - SCRD

VP19-SCR-01-00-RPT-EN-Enviromental-Assessment-Rev1.docx 28 October 2019 | Page 3

either Site C3 or C4. No existing surface water bodies have been mapped within the footprints of Sites A and B.

A search of the Freshwater Atlas Wetlands database in iMapBC was completed andno wetlands were identified within the boundaries of the Sites; however, there ispotential for wetlands to exist within the Site C3 and C4 footprints, based on a reviewof the available satellite imagery. (GoBC 2019b).

Sites A and B are situated within close proximity (300 m and 225 m, respectively) ofimportant or special habitats, including the provincially protected (Red List) SitkaSpruce / Salmonberry Dry Ecosystem, whereas Sites C3 and C4 are not.

A review of the Archaeology and Culture Areas layers within iMapBC was completed,to document potential archaeological, cultural, or historic resources within theboundaries of the Sites. No archaeological, cultural, or historic resources weredocumented within the boundaries of the Sites (GoBC 2019b). This search was basedon a review of limited publicly available information. A registered Archeologist will berequired to conduct the appropriate assessment for each of the Sites.

A search of the Environmental Remediation Sites database in iMapBC was completedand no results were located within the boundaries of the Sites (GoBC 2019b).

Sites A and B are situated primarily within the Agricultural Land Reserve (ALR). Thepriority land use in the ALR is agricultural. The Agricultural Land Commission (ALC)approves all other non-agricultural uses, please refer to the Regulatory Roadmap(integrated Sustainability 2019c).

3.2 Preliminary Environmental Risks Upon review of the environmental field data obtained to date coupled with Integrated Sustainability desktop reports (Integrated Sustainability 2018, Integrated Sustainability 2019a, 2019b, 2019c, 2019d, 2019e) the following preliminary environmental risks have been identified for the Sites as outlined in Table A. At this phase of the Project and based on the information that has been collected to date, all Sites are deemed feasible from an environmental perspective. Although further Site-specific field investigations will be required to evaluate the feasibility for each Site.

Table A. Preliminary Environmental Risks

Preliminary Environmental Risk

Site A Site B Site C3 Site C4

Degradation of the Chapman Creek catchment area.

Site A is situated such that water would be conveyed from Chapman Creek to the reservoir via pipeline, with potential contributions from natural surface water inflow and groundwater. Water would then be conveyed from the reservoir to the Chapman Creek WTP via pipeline (Integrated Sustainability 2019e).

Site B is situated such that water would be conveyed from Chapman Creek to the reservoir via pipeline, with potential contributions from natural surface water inflow and groundwater. Water would then be conveyed from the reservoir to the Chapman Creek WTP via pipeline (Integrated Sustainability 2019e).

Site C3 is situated such that the reservoir would capture surface water from the local watershed, including an unnamed creek that drains to the lake basin from the northwest. Water would be released from the reservoir into Chapman Creek via Tsawcome Creek (Integrated Sustainability 2019e).

Site C4 is situated such that the reservoir would capture surface water from the local watershed. Water would be released from the reservoir into Chapman Creek via the unnamed creek between Sites C3 and C4 and then via Tsawcome Creek between Site C3 and the confluence of Tsawcome Creek and Chapman Creek. Given this, water conveyed from Site C4 would travel through the Site C3 lake basin on its path to Chapman Creek (Integrated Sustainability 2019e).

Preliminary Environmental Risk

Site A Site B Site C3 Site C4

The material required for the construction of the reservoir may cause adverse environmental impacts, especially by aggravating dust pollution, disturbing wildlife and destroying vegetation.

All reservoirs have the potential to create adverse environmental impacts: dust will affect human health more at Sites A and B, wildlife may be disturbed more at Sites C3 and C4 as well as vegetation destruction.

The reservoir has a conceptual design storage volume of approximately 1,000,000 m3. Given the existing topography, the north portion of the reservoir would require a cut and the south portion of the reservoir would require an embankment dam (Integrated Sustainability 2019e).

The reservoir has a conceptual design storage volume of approximately 1,200,000 m3. Given the existing topography, an embankment dam would be required on all sides of the reservoir, with an embankment dam on the south side being greater in height than those on the north side (Integrated Sustainability 2019e).

The reservoir has a conceptual design storage volume of approximately 1,000,000 m3. The conceptual layout for Site C3 includes a dam positioned at the south end of the lake basin, used to capture water within the lake basin to create a reservoir constrained by the dam and valley slopes surrounding the lake basin (Integrated Sustainability 2019e).

The reservoir has a conceptual design storage volume of approximately 700,000 m3. The conceptual layout for Site C4 includes a dam positioned at the south end of the lake basin, used to capture water within the lake basin to create a reservoir constrained by the dam and valley slopes surrounding the lake basin (Integrated Sustainability 2019e).

4 ADDITIONAL SCOPE OF WORK

4.1 Environmental Assessment Certificate To provide clarity and transparency and to ensure that environmental impacts and the issues and concerns of the public, Indigenous communities, stakeholders, and government agencies are being addressed, an environmental assessment is required for major projects in BC (Province of British Columbia 2018). An environmental assessment identifies, mitigates, and evaluates for potentially adverse environmental, economic, social, heritage, and health effects that may occur during the life of a reviewable project (Province of British Columbia 2018), as shown in Figure A.

Figure A. Environmental Assessment Components The BC Environmental Assessment Office (EAO) provides direction on the framework and guidance to support the preparation and submission of the Application Information Requirements (AIR). The AIR should be submitted to the EAO following required environmental field investigations (Section 4.3) during the pre-application phase (in future phases of the Project), to ensure the application provides all the necessary documentation required for an Environmental Assessment Certificate (EAO 2015).

Once the environmental field investigation has been completed, the AIR and supporting documents will need to be developed for submission to the EAO. The Environmental Assessment Act requires an assessment to consider the environmental, economic, social, heritage, and health effects of a reviewable project, both in the short-term during construction and the long-term during operations and reclamation. EAO refers to these broadly as ‘pillars’ (EAO 2013).

The AIR includes an identification of Valued Components (VCs) which will drive the overall scope of assessment, baseline data collection work, and associated indicators required. Additionally, the AIR outlines the information needed to describe the potential effects of the proposed project on the VCs, and ways those effects will be assessed (EAO 2015).

The AIR is supported by other documents, such as the proponent’s Project Description, the Valued Component Selection Document and the proponent’s Consultation Plans for undertaking consultation with various groups and stakeholders (EAO 2015). Early engagement with the EAO is recommended in the pre-application stage to ensure alignment prior to development of the AIRs and VCs. The EAO will review the VCs and associated indicators with the working group for assessment before finalizing the AIR. At this time, the EAO will provide direction for any baseline environmental studies (Section 4.4) that may be needed to support the AIR. The proponent must also prepare a report on the public and First Nations consultation activities that they have completed and how they plan to consult during the review of their application (EAO 2015).

The EAO will begin the application review once the application has been accepted as complete and has 180 days to conduct its review from time of acceptance.

4.2 Desktop Assessment Recommendations All required desktop assessments have been completed at this time, please refer to Integrated Sustainability desktop reports (Integrated Sustainability 2018, Integrated Sustainability 2019a, 2019b, 2019c, 2019d, 2019e).

4.3 High-Level Field Investigation Recommendations An onsite environmental field assessment is recommended at the Sites to confirm conditions identified during the desktop study. The assessment is to be conducted during the growing season by a QEP and should include the following for the Sites at a minimum to support the AIR for submission to the EAO:

Review of the site locations and description details.

Review of Archaeological Overview Assessment studies.

Landscape and topography assessment.

Identification and classification of water bodies (riparian classes including streams, wetlands, lakes, and Non-Classified Drainages (NCD), and riparian management areas).

Identification of water bodies with fish potential (identification of features that require a fish habitat assessment).

Characterization of soil horizons including profile, texture, colour, and moisture for soil conservation planning.

Vegetation assessment including dominant species for reclamation planning, potential for species at risk, and invasive plant presence and potential.

Page 14: Raw Water Reservoir Feasibility Study - SCRD

VP19-SCR-01-00-RPT-EN-Enviromental-Assessment-Rev1.docx 28 October 2019 | Page 10

Identification of any wildlife or important wildlife habitat (including species at risk, endangered species, regionally important wildlife, and ungulate species) that may require additional wildlife assessments by a QEP.

Additionally, a wildlife sweep is recommended prior to disturbance (including the geotechnical program) of the Sites within the breeding bird nesting period from late April and late August (Environment Canada 2019).

Information collected during the field investigation will be incorporated into preparation of the AIR and supporting documents. Refer to the Regulatory Roadmap for supporting documents (Integrated Sustainability 2019c).
