Table 10 2200 Portal (Tunnel Mine) Site Reconnaissance Potential Issues Findings Vehicle access to the site is via the road coming from Britannia Beach. Site Lay-Out and Access Access to the portal is restricted, however, the rest of the site is accessible Surface Water Drainage Building Construction, Heating and Cooling Stressed, Stained or Dead Vegetation Ponds/Lagoons Drains/Sumps/Pits/Oil- Water Separators/Catch Basins Solid Waste, Hazardous Materials and Hazardous Waste Underground Storage Tanks and Aboveground Storage Tanks(USTs/ASTs) Hazardous Building Materials (PCBs, asbestos, ozone-depleting substances) 4.2.2 Mt. Sheer Townsite by foot. Mine water flows from the mine portal. Surface water flows from the south slopes adjacent to the site (Photograph 20, Appendix E). Surface water infiltrates into the ground as well as running to Jane and Britannia Creeks. The former powerhouse was constructed of timbers with metal cladding on the sides and roof. Piles of rubble are all that remain of other buildings. There is no heating or cooling. Evidence of vegetation that appeared stressed, stained or dying was not observed; however, contaminant impact to soils was evident by a complete absence of vegetation in many areas, notably near the site of the historic copper plant and in the vicinity of the portal. Impact from metal contamination was indicated by staining on the ground (Photograph 21, Appendix E); the orange colouration of the mine drainage flowing from the tunnel portal suggested the presence of acid rock drainage (Photograph 20, Appendix E). As part of the current remediation activity at the 2200 level, a settling pond has been constructed to which the mine water is diverted prior to discharge into Jane Creek. No evidence was observed. Britannia Contaminated Site Investigation Stage I Preliminary Site Investigation Project No. 50319-001-310 28 As mine operations have ceased, there are no solid or hazardous wastes generated or hazardous materials utilized. There is evidence of the historic deposition of mine waste rock throughout the site (Photograph 22, Appendix E). A strong odour of petroleum hydrocarbons was detected around machinery remaining inside the powerhouse, indicating the potential for petroleum hydrocarbon contamination. There was no evidence of USTS or ASTs. There was no evidence observed of hazardous building materials. Table 11 Mt. Sheer Townsite Site Reconnaissance Findings Potential Issues Findings Site Occupants and Activities The townsite is abandoned and with the exception of logging trucks passing through the townsite, there was no evidence of ongoing activities. No buildings were observed, however, the in-ground swimming pool is still visible and the concrete remnants of the historical copper launder remain (Photograph 23, Appendix E). Site Lay-Out and Access There did not appear to be any significant deviations from the site layout
Table 11 Mt. Sheer Townsite Site Reconnaissance Findings Potential Issues Findings depicted on historical maps. The former railway beds are now utilized as roads. There is a gentle to moderate slope to the south. Surface water drains into Surface Water Drainage Britannia Creek as well as infiltrates into the ground. Building Construction, N/A Heating and Cooling Stressed, Stained or Evidence of stressed, stained or dead vegetation was not observed. Dead Vegetation Ponds/Lagoons No ponds or lagoons were observed. Drains/Sumps/Pits/Oil- None observed. Water Separators/Catch Basins Solid Waste, Hazardous Waste materials, consisting primarily of scrap metal, were observed around Materials and Hazardous the historical copper launder (Photograph 24, Appendix E). Waste Underground Storage No evidence of current or historical USTs or ASTs was observed. Tanks and Aboveground Storage Tanks(USTs/ASTs) Hazardous Building N/A Materials (PCBs, asbestos, ozone-depleting substances) 4.2.3 Victoria Camp Table 12 Victoria Camp Site Reconnaissance Findings Potential Issues Findings Site Occupants and The camp is abandoned and, with the exception of logging trucks passing Activities through, there was no evidence of ongoing activities. The absence of buildings makes it difficult to determine the locations of Site Lay-Out and Access historical structures. The locations can be determined by orienting with the remaining portals and shafts. Surface Water Drainage The site slopes to the south towards Furry Creek. Surface water runs towards the creek as well as infiltrating into the ground. Building Construction, Heating and Cooling N/A Stressed, Stained or Evidence of vegetation that appeared stressed, stained or dying was not Dead Vegetation observed. Ponds/Lagoons There were no ponds or lagoons observed. Drains/Sumps/Pits/Oil- Water Separators/Catch Basins None were observed. Solid Waste, Hazardous Materials and Hazardous Waste Waste material consists of large piles of mine waste rock generated during mine operations (Photograph 25, Appendix E). A large mound of sawdust at the historical sawmill site reported by former mine employees was not discovered.
