3 Pre-Renovation Hazardous Building Material Assessment October 11, Howe Street, Vancouver, BC Page 3 DST File No.: GV-VC requirements for worker protection, safe work procedures and principles that should be followed in selecting the most suitable technique for the safe abatement of lead Elemental Mercury Mercury-containing equipment is regulated under Part 5, section 5.49 of the BC OH&S Regulation Hazardous Wastes In British Columbia, environmental matters pertaining to waste generally fall under the jurisdiction of the British Columbia Ministry of Environment (MoE), pursuant to the Environmental Management Act. The key waste regulation under the Environmental Management Act relating to hazardous building materials is the Hazardous Waste Regulation (HWR), as amended from time to time. The HWR provides the requirements for the proper handling, storage, transportation, treatment, recycling and disposal of hazardous wastes in the province. The regulation also outlines the materials and criteria to be used to characterize waste as hazardous. Applicable Federal Legislation Halocarbon and Ozone Depleting Substances (ODS) Halocarbon and Ozone Depleting substances are regulated under the Canadian Environmental Protection Act (CEPA), Federal Halocarbon Regulations, 2003, (SOR/ ) Transportation of Dangerous Goods The transportation of hazardous wastes is governed under the Transportation of Dangerous Goods (TDG) Act and Regulations which outline the requirements for storage, handling, and transportation of hazardous waste, amongst other products. 4.0 METHODOLOGY Suspect hazardous building materials were visually identified based on the surveyor's knowledge of historical composition of building products. Visual identification of materials suspected to contain asbestos or lead (in coatings) were supported by the analysis of representative samples. Suspect ACM samples were analyzed for asbestos content at AASL, by Polarized Light Microscopy (PLM), following NIOSH Method DST Consulting Engineers Ltd.

4 Pre-Renovation Hazardous Building Material Assessment October 11, Howe Street, Vancouver, BC Page 4 DST File No.: GV-VC Suspect LBC samples were analyzed for lead content at Maxxam Analytics, by inductively coupled plasma-atomic emission spectrometry (ICP-AES), following EPA 6010c R3 m. Painted surfaces that were identified to contain a concentration of lead equal to or greater than 90 mg/kg were classified as having a hazardous level of lead and were considered a LBC. Suspected ozone-depleting substances (ODSs), elemental mercury and sources of polychlorinated biphenyls (PCBs) were visually identified based on appearance, age, and knowledge of historic applications/locations. 5.0 FINDINGS The following sections outline the findings of DST s hazardous building material assessment. Certificates of analysis are provided in Appendix I of this report.

If additional suspect ACMs are discovered through the course of renovation/demolition work, stop the work and treat the suspect ACM as an ACM until it can be sampled and analyzed for asbestoscontent. Furthermore, DST recommends reference to WorkSafeBC publication, Safe Handling of Asbestos, A Manual of Standard Practices. This document provides a guide to current practices that are to be followed in the Province of British Columbia, providing basic information on asbestos and asbestos products, health hazards and requirements for worker protection, safe work procedures and principles that should be followed in selecting the most suitable technique for the safe abatement of ACMs. DST Consulting Engineers Ltd.

14 Pre-Renovation Hazardous Building Material Assessment October 11, Howe Street, Vancouver, BC Page 14 DST File No.: GV-VC Lead-Based Coatings (LBCs) LBCs that will be disturbed through renovation/demolition work must be controlled using safe work procedures developed in accordance with the requirements of WorkSafeBC, specifically, but not limited to include those requirements prescribed through Parts Controlling Exposure, and Parts Lead of the BC OH&S Regulation. Furthermore, DST recommends reference to WorkSafeBC publication, Lead Preventing Exposure at Work. This document provides a guide to current practices that are to be followed in the Province of British Columbia, providing basic information on lead and lead products, health hazards and requirements for worker protection, safe work procedures and principles that should be followed in selecting the most suitable technique for the safe abatement of lead. DST also recommends that Toxicity Characteristic Leaching Procedure (TCLP) testing should be performed on LBCs to facilitate the proper disposal of lead-containing waste. Lead-containing wastes should be disposed of in accordance with the British Columbia Ministry of Environment and should be transported in accordance with the requirements of the Federal Transportation of Dangerous Goods Act. Mercury-Containing Equipment If taken out of service, mercury-containing wastes should be managed in accordance with the requirements of the British Columbia Ministry of Environment and should be transported in accordance with the requirements of the Federal Transportation of Dangerous Goods Act. Polychlorinated Biphenyl s (PCBs) When taken out of service, the PCB-content of each fluorescent lamp ballast should be verified through comparison to the criteria outlined in the Environment Canada Report EPS 2/CC/2 (revised) August 1991, Identification of Lamp Ballasts Containing PCBs to assess their likelihood of PCB content. If identified to contain PCBs, the PCB-containing light ballasts should be removed in accordance with the requirements of WorkSafeBC. PCB-containing wastes should be managed in accordance with the requirements of the British Columbia Ministry of Environment and should be transported in accordance with the requirements of the Federal Transportation of Dangerous Goods Act. For fixtures that are operational and are to be sold for reuse, documentation is required confirming that the purchasers understand the ballasts are PCB-containing, and the purchaser assumes all liability and responsibility associated with the fixtures.
