1.0 INTRODUCTION
SLR Consulting (Canada) Ltd. was retained by Chevron to conduct a biological assessment at the foreshore area adjacent to the Chevron Burnaby Refinery, Burnaby, BC (hereafter referred to as the Site). The biological assessment included a biological survey and information review pertaining to applicable sediment criteria for the Site.
The Site is in Burrard Inlet adjacent to the Chevron Refinery in Burnaby, BC (Figure 1 and Figure 2). Burrard Inlet is divided into five major harbours: Outer, Inner, Central, Indian Arm, and Port Moody Arm as well as False Creek (BIEAP Report, 2009). The Site is located on the south shore within the Central Harbour.
This report summarizes findings of the biological survey and biological information review.
2.0 BIOLOGICAL SURVEY
2.1 Approach Prior to conducting the biological survey, SLR compiled a list of ecological receptors potentially present at the Site that included:
Review of Schedule 1 of the Species at Risk Act for Schedule 1 species anticipated near the Site;
Review of the BC Ministry of Environment’s Conservation Data Centre (CDC) database of red- and blue-listed animal and plant species specific to the Site biogeoclimatic zone;
Review of the CDC map of known locations of red- and blue-listed species near the Site, including the map’s associated Element Occurrence Records;
Review of BC MOE’s Fisheries Information Summary System (FISS) database for Burrard Inlet;
Review of biological information on the Sensitive Habitat Inventory and Mapping System, http://www.shim.bc.ca/shim/SHIM_public.htm; and,
Review of the Community Mapping Network (http://www.cmnbc.ca/) for the Burrard Inlet Environmental Action Plan (BIEAP) Atlas.
The biological survey of the foreshore was completed in accordance with relevant protocols and guidance provided in the following documents:

2.2 Identification of Receptors
2.2.1 Site Biogeoclimatic Zone Burrard Inlet is a part of the Pacific Marine Ecozone (PME) extending from Alaska and the Bering Sea in the north to Oregon and the Pacific Ocean in the south (BIEAP, 2009). The site is located within the Coastal Western Hemlock (CWH) Biogeoclimatic Zone of BC and is characterized by cool, wet winters and mild summers. The site is considered to be in the Dry Warm Interior sub-zone of the CWH zone (CWHdm).
2.2.2 Threatened or Endangered Species Potentially Using the Site
Schedule 1 of Canada’s Species at Risk Act (SARA) is a list of federally (Canada-wide) Endangered, Threatened, or ‘of Special Concern’ species. A search of the Species At Risk Act Registry identified that the general Site area was associated with the potential presence of twenty-two SARA-listed species. Of these twenty-two species, two species listed in Schedule 1 of the Species at Risk Act (SARA) were determined to potentially use the site due to habitat preferences:
In addition to this federal information, the BC Ministry of Environment’s CDC ranks species Province-wide. BC classifies at-risk species as red-listed or blue-listed. The BC CDC’s database of red- and blue-listed species present within the Coastal Western Hemlock (CWH) Biogeoclimatic Zone, specifically in the Dry Maritime sub-zone (CWHdm), includes seventy-three species. Of these seventy-three species, eight species were determined to potentially use the site due to habitat preferences:
Red-listed species Blue-listed species
Brandt’s cormorant Dolly Varden
Green sturgeon Double-crested cormorant
Pelagic cormorant subsp. pelagicus Great blue heron subsp. fannini
Surf scoter
California gull
A search using the Sensitive Habitat Inventory and Mapping System (SHIM) did not return sensitive habitats near the Site. A search using FISS did not return any observations of fish species in the creeks adjacent to the Site.
Information posted on Fisheries and Oceans Canada Website indicates that the Site is within a Rockfish Conservation Area (Pacific Region Area 28 - Eastern Burrard Inlet - Chart 3494). Most
Threatened species Special Concern species
Red knot Roselaari type Great blue heron subsp. fannini

rockfish are present in deep waters where they consume amphipods, shrimp, crabs, and fish depending on species and life stage. However, Copper rockfish (Sebastes caurinus) is also found in kelp beds and shallow rocky areas as well as juveniles of Yelloweye rockfish (Sebastes ruberrimus) and Quillback rockfish (Sebastes maliger) are found in shallower inshore areas.
2.3 Biological Survey The biological field survey was conducted by Celine Totman, a BC R.P.Bio, on July 12, 2010 during low tide, and included observations of biota and flora, physical features of the habitat, including species composition, spatial distribution, and distinct natural and manmade features. Photographs representative of the Site features and conditions were taken during the survey and are provided in Appendix A.
The biological survey consisted of qualitative observations on the habitat, fauna and flora observed on the foreshore at the Site, immediately downstream of the seepages, about 50 meters west from the Environment Canada Weather Station. The foreshore adjacent to the site (east and west of the site) was also surveyed.
2.3.1 Biological Survey at the Site
Intertidal substrates at the Site consisted of sand, fine gravel, cobble and boulder. The macrofauna was limited at the site with barnacles being the dominant group; gastropods, limpets, bivalves and crabs were not observed at the Site. Note that cleanup and environmental investigation activities have been completed at the Site prior to and during the biological survey.
The upper intertidal zone of the Site consisted of boulders, cobble and sand. The western and eastern halves of the upper intertidal zone were somewhat different. The western half consisted of approximately 70% boulder and 30 % cobble with sand underneath while the eastern half had more exposed sand substrate (approximately 40% sand, 35 % boulders and 25% cobble) (Photos 1 and 2). Barnacles were the dominant macrofauna group in the upper intertidal zone. Small patches of rockweed (Fucus sp.) were observed, however the algae cover was low (<10% of the upper intertidal zone). Some stained boulders were observed immediately downstream of the seepage.
The middle intertidal zone of the Site consisted of approximately 60% sand and fine gravel, 30% cobble and 10% boulder. Similarly to the upper intertidal zone, barnacles were the dominant macrofauna group. Patches of rockweed (Fucus sp.) were observed on boulders (Photo 2).
The lower intertidal zone of the Site was dominated by approximately 90% sand and fine gravel with about 10% boulder. The lower intertidal zone contained the highest abundance of algae with rockweed (Fucus sp.), sea lettuce (Ulva sp.), and sugar wrack (Laminaria saccharina) attached to the boulders (Photos 4 and 5). Limited amounts of Bull kelp (Nereocystis luetkeana) was also present in the shallow subtidal zone.
2.3.2 Biological Survey of the Foreshore Adjacent to the Site
The foreshore located east and west of the Site was somewhat different than the site. It consisted of rocky shore, and had a more abundant algal and macrofauna community.
Chevron SLR Project No.:201.00959.0000.0002 Biological Survey August 2010
4 CONFIDENTIAL
The upper intertidal zone was dominated by boulders (85%) with some cobble (15%) on top of sand. The boulders were covered with rockweed (Fucus sp.). Little rockweed (Pelvetiopsis limitata) was also attached to boulders in the area (Photos 6 and 7).
The middle intertidal zone consisted of cobbles with some pockets of sand present in the area immediately between the upper and middle intertidal zones. Some boulders were present but with limited coverage (about 5%). Sea lettuce (Ulva sp.) covered approximately 10% of the cobble substrate (Photos 6 and 9).
The lower intertidal zone consisted of thick mats of sea lettuce (Ulva sp.) covering the cobble substrate. Closer to the low tide water line, sugar wrack (Laminaria saccharina) was abundant. Bull kelp (Nereocystis luetkeana) was abundant in the shallow subtidal zone (Photos 8 and 10) which corresponds with BIEAP’s draft vegetation report (Figure B-3; BIEAP Habitat Report, 2009).
The macrofauna was more diverse on the foreshore on the east and west of the Site with the following species observed:
Smooth Washington clam (Saxidomus gicanteus) Common Pacific littleneck (Protothaca staminea) Leather star (Dermasterias imbricata) Ochre Sea Star (Pisaster ochraceus) Dungeness crab (Cancer magister) Black-clawed mud crab (Lophopanopeus bellus) Unidentified worms
Sea gulls were observed foraging among the sea lettuce (Ulva sp.) bed.
None of the above observed plants and animals are federally or provincially listed. It cannot be assumed, however, that regionally listed species do not inhabit or incidentally cross this Site during some lifecyle phase.
3.0 INFORMATION REVIEW – APPLICABLE SEDIMENT CRITERIA The scope of work of the Stage 2 PSI includes the collection of sediment samples, and comparison of the analytical results to the Contaminated Sites Regulation (CSR) standards including Schedule 9 Sediment Criteria (ecological health). BC MOE suggested sediments at the Site be considered under sensitive sediment use as per the CSR and requested this be confirmed though review of ecological information for the area and discussion with various interested parties including the Burrard Inlet Environmental Action Program (BIEAP) staff.
3.1 Methodology The Regulation defines typical sediment use as one that is not sensitive sediment use. The Criteria for Managing Contaminated Sites in BC – Technical Appendix outlines the criteria for which Sediment Quality Criteria for Sensitive Contaminated Sites (SQCSCS) apply.
Chevron SLR Project No.:201.00959.0000.0002 Biological Survey August 2010
5 CONFIDENTIAL
SLR reviewed information obtained from the databases, websites, documents and interviews listed in the References section of this report to determine if any of the criteria for sensitive sediment use are applicable at the Site.
3.2 Schedule 2 (Technical Appendix) Criteria Investigation The results are presented in a ‘lines of evidence’ approach in Table 1.
Table 1: Schedule 2 Criteria for areas to which SQCSCS should be applied.
C-1
“Areas, sites or reaches which support red and blue listed plants and animal species, or nests designated under the Wildlife Act (BC).”
Under the Wildlife Act (BC), three red-listed and five blue-listed species were determined to potentially use the site.
Under the Species at Risk Act, one threatened and one Special Concerned species were determined to potentially use the site. See Section 2.2.
None of these species were observed at the Site during the field visit, although it cannot be assumed that regionally listed species incidentally cross the Site during some lifecycle phase (Indicators Report, 2008). However, it is probable that these species would more likely use the portion of foreshore to the east and west of the Site as the algal and macrofauna communities are more abundant and diverse at these locations.
C-2
“Habitats used by endangered or threatened species, or species of special concern under the Species at Risk Act.”
C-3
“Watercourses, wetlands, forested riparian areas, mudflats and intertidal zones that are important to preservation of fish and wildlife.”
There are no watercourses, wetlands or mudflats within or immediately adjacent to the Site. The riparian area is limited as it is part of the railway corridor.
The Site includes an intertidal zone (see Section 2.3.1) which was classified as purpose built high value habitat (BIEAP Report, 2009).
C-4
“Reaches of aquatic habitats that are important to fish spawning or serve as important rearing habitat for fish.”
The Site is not within a Department of Fisheries and Oceans Marine Protected Area.
The Site is within a Rockfish Conservation Area (Pacific Region Area 28 - Eastern Burrard Inlet - Chart 3494). Most rockfish are however present in deep waters where they consume amphipods, shrimp, crabs, and fish, depending on species and life stage. Juveniles can be found in kelp beds and shallower rocky areas. Based on the observations made during the Site visit it is likely juvenile rockfish would use the natural rocky foreshore to the east and west of the Site as the lower intertidal zone immediately downstream of the seepages is sandier and only included limited patches of Bull kelp.
C-5
“Reaches of aquatic environments encompassing, and/or bordering habitat compensation or restoration sites, or other areas that are intended or designed to create, restore or enhance
The Site and foreshore bordering the Site are not, at this time, part of habitat compensation or restoration sites. - The foreshore adjacent to the Site includes an intertidal
zone (see Sections 2.3.2) which was classified as purpose built high value habitat (BIEAP Report, 2009).
Three natural feature parks exist in the Central Harbour, but they do not directly border the Site. - The Maplewood conservation Area (MCA) is an area of high

biological or habitat features.”
sensitivity across Burrard Inlet from the Site. The MCA is comprised of tidal flats used by foraging seabirds and shorebirds and are a key resource for migrating species. This habitat differs significantly from the sandy and rocky intertidal habitats at the Site.
- The City of Burnaby is working on a Burnaby Mountain Management Plan and a Barnet Marine Park Master Plan. However, Barnet Marine park and Burnaby Mountain Conservation Area are 3 km east of the site.
C-6
“Areas of unique habitat that are identified in provincial or municipal landuse plans.”
Goals of the Consolidated Environmental Management Plan for Burrard Inlet include to minimize the effects of contaminated soils and sediments on ecological health, maintain and enhance productive fish and wildlife habitat and the natural biodiversity of Burrard Inlet, and to encourage development activities that enhance the environmental quality of Burrard Inlet. - The City of Burnaby is currently working on the Burrard Inlet
Foreshore and Upland Management Plan and the Environmentally Sensitive Areas Strategy. The information is not yet available to assess if this criterion may apply to the site.
C-7
“Reaches of aquatic environment that exist within provincial marine parks, provincial parks, or ecological reserves.”
The Site is not within a provincial marine park, provincial park, or ecological reserve.
C-8
“Areas and aquatic habitat included within provincial Wildlife Management Areas.”
The Site is not within a designated BC Wildlife Management Area or a designated a National Wildlife Area by Environment Canada.
C-9
“Areas covered under conservation agreements and areas designated as “Environmentally Sensitive” in municipal land use plans or strategies.”
Although the BIEAP Report (2009) recommended that Central Harbour has the greatest potential value for important marine organisms, the Site is not at this time within an area designated as environmentally sensitive.
3.3 Historical Application of Sediment Quality Standards in Burrard Inlet The CSR sediment quality standards are available for both typical and sensitive sediment uses. Sediment quality standards specific to Burrard Inlet have also been published for polycyclic aromatic hydrocarbons (PAHs). These objectives are based upon existing PAH concentrations in sediments in other areas of the Lower Mainland and on Apparent Effects Thresholds determined for PAHs in Puget Sound Sediments. Consequently, the sediment quality objectives for Burrard Inlet are even lower than the SQCSCS outlined in Schedule 9 of the CSR and concentrations in sediments frequently exceed these specific objectives. As a result, the specific Burrard Inlet sediment quality objectives are considered long-term in nature and are not appropriate for immediate direct comparison with concentrations measured in sediment samples at the Site.

7 CONFIDENTIAL
Mr. Juergen Baumann at the Vancouver Port Authority indicated that the Site and foreshore adjacent to the Site is normally considered as a typical sediment use due to industrial nature of the foreshore and background sediment quality.
4.0 CONCLUSION
4.1 Biological Site Survey
The Site, immediately downstream of the seepages, about 50 meters west from the Environment Canada Weather Station consisted of sand, fine gravel, cobble and boulder. The upper intertidal area was rocky while the middle and lower intertidal areas were sandier. The macrofauna was limited at the site with barnacles being the dominant group, gastropods, limpets, bivalves and crabs were not observed at the Site. Limited patched of algae were present.
The foreshore located east and west of the Site consisted of natural rocky intertidal areas with abundant algal community and a more diverse macrofauna community. These rocky areas form better intertidal habitat than found at the Site.
The foreshore, at the site location, forms a point of land; this geographical feature likely contributes to the difference in substrate observed at the Site. Cleanup and environmental investigation activities have also been completed at the Site prior to and during the biological survey. It is however unlikely these activities would have caused significant changes to the substrate and to the macrofauna distribution.
4.2 Information Review – Applicable Sediment Criteria
Based on the site visit, review of biological information and interviews, it is recommended that the sediments in the immediate area of interest be considered as typical sediment use.
