3 Final Pre-Demolition Hazardous Building Material Survey September 2, 2015 Western Stevedoring 95 Brooksbank Avenue, North Vancouver, BC DST File No.: BE-VC Hazardous Materials & Demolition/Renovations Section of the BC OH&S Regulation details the requirements that employers and owners are responsible for before beginning work on the demolition, renovation or salvage of machinery, equipment, buildings, or structures. The employer or owner must: Inspect the site to identify any asbestos, lead and/or other potentially hazardous materials that may be handled, disturbed, or removed; Have the inspection results available at the worksite; and, Ensure that the hazardous materials are safely contained or removed 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 Asbestos-Containing Materials (ACMs) ACMs are regulated under Part 6 (sections 6.1 to 6.32) of the BC OH&S Regulation. General requirements prescribed in these sections are summarized below: Section 6.1 Definitions According to this section of the OH&S Regulation, an ACM is defined as any manufactured article or other material, other than vermiculite insulation, that would be determined to contain at least 0.5% asbestos through analytical testing. Materials other than vermiculite must be tested in accordance with one of the following methods: Asbestos, Chrysotile by XRD, Method 9000 (Issue 2, dated August 15, 1994) in the NIOSH Manual of Analytical Methods, published by the United States National Institute for Occupational Safety and Health, Centre for Disease Control; Asbestos (bulk) by PLM, Method 9002 (Issue 2, dated August 15, 1994) in the NIOSH Manual of Analytical Methods, published by the United States National Institute for Occupational Safety and Health, Centre for Disease Control; or, DST Consulting Engineers Inc.

21 Final Pre-Demolition Hazardous Building Material Survey September 2, 2015 Western Stevedoring 95 Brooksbank Avenue, North Vancouver, BC DST File No.: BE-VC DST recommends reference to WorkSafeBC publication Safe Handling of Asbestos, A Manual of Standard Practices (WorkSafeBC Guideline). 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. Based on the recommendations provided in the WorkSafeBC Guideline, the abatement of asbestos-containing vermiculite block wall insulation should be completed following High Risk asbestos abatement protocols. In addition, a structural engineer should be retained to review and approve the methodology for selective demolition (i.e. disturbance to the cinder block wall to remove vermiculite insulation). Asbestos-containing wastes should be managed 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. NOTE: As the Subject Facility was occupied and operational at the time of our assessment, DST recommends that additional destructive bulk sampling be conducted to the roof systems prior to any demolition activities to identify potential concealed hazardous building materials. 7.2 Lead-Based Coatings (LBCs) DST recommends that LBCs that may be impacted during restoration activities be removed in accordance with the requirements of WorkSafeBC. The disturbance of LBCs should be controlled through use of safe work procedures. Work procedures must be developed in accordance with the requirements of WorkSafeBC, specifically but not limited to include those requirements prescribed through Parts Controlling Exposure, and Parts Lead. Toxicity Characteristic Leaching Procedure (TCLP) testing should be performed on identified lead-based paint, to facilitate the proper disposal of lead-containing wastes. 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.
