1 REAL ESTATE & FACILITIES MANAGEMENT Facilities Planning & Development Hazardous Materials Survey of: Champlain Heights Community Centre (Sloped Roof & Skylights) Building Code: 3210 Address: 3350 Maquinna Drive Surveyor: Patrick Li Work Notification Number: Requested By: Desh Jehman Purpose: TARGETED HAZARDOUS MATERIAL SAMPLING Executive Summary A City of Vancouver Hazardous Materials Technician has completed a Targeted Hazardous Material Sampling Survey of the Sloped Roof & Skylights at 3350 Maquinna Drive - Champlain Heights Community Centre. A targeted hazardous material sampling survey only identifies the hazardous building materials that could be encountered or disturbed in a specified area (Sloped Roof & Skylights). Although this was a semi-destructive survey, any hidden materials that were not addressed which may contain asbestos or lead should be assumed to be hazardous until sampling demonstrates otherwise.

2 Scope of Work A visual inspection of the sloped roof & skylight areas at the Champlain Heights Community Centre for the presence of building materials suspected to contain asbestos or lead. Surficial and Test Cut sampling were conducted. An assessment of potentially hazardous materials, denoting their condition, potential for disturbance/damage, accessibility to workers or public, estimated quantity, if suspect asbestos containing, their friability, potential for fiber release and worker exposure was assessed. Collection and analysis of material samples from the roof areas for the presence of suspect hazardous materials. A risk assessment for the current condition of any damaged asbestos/lead containing materials determined to be present within the buildings including the priorities for removal/repairs. Recommendations for the removal/repair of any damaged hazardous materials determined to require immediate action. Asbestos-Containing Material: Methodology and Results Materials sampled were selected based on our experience and guidelines provided by WorkSafeBC (Safe Work Practices for Handling Asbestos). Building materials were assessed for potential asbestos content and have been analyzed for asbestos by COV-approved labs. NO asbestos was found in any of the samples analyzed.

3 Lead-Based Paints and Coatings: Methodology and Results Total Lead in Paint Representative samples of paint were collected to test for the presence of lead. The sample was analyzed at a COV-approved lab for total lead. Information from the U.S. Occupational Safety and Health Administration (OSHA) suggests that the improper removal of lead paint containing 600 mg/kg lead results in airborne lead concentrations that exceed half of the exposure limit. Depending on the potential receptors and the work to be performed, paints with lead contents as low as 90 mg/kg can also result in dangerous airborne lead levels. A task-, and site-specific risk assessment must be conducted by City of Vancouver s Hazardous Materials Team to determine if an Exposure Control Plan and safe work procedures are required (Lead- Containing Paints and Coatings: Preventing Exposure in the Construction Industry, WSBC 2011). All paint samples exceeded the suggested exposure prevention limit of 600 mg/kg paint (Table 2). Leachable Results of Lead in Paint The Canadian Hazardous Waste Regulation specifies the limit for concentration of leachable lead extracted in waste samples as 5mg/litre. The paint sample was determined to be below the limit of 5mg/L, therefore is non-leachable and is not classified as a hazardous waste as defined by the BC Ministry of Environment Table 2: Materials Sampled and Analyzed for the Presence of Lead and Leachable/Hazardous Waste MAXXAM Lab Reference No. B Sample No. Location Description RESULTS (mg/kg) 3210EXT-L01 East End Light Green Paint on Wooden Trim/Post EXT-L02 North East End Green Paint on Wood Trim/Window Sill EXT-L03 East End Dark Green Paint on Wood Siding EXT-L04 South End Roof Valley Light Green Paint on Wooden Beam EXT-L05 South West End Dark Green Paint on Wood Siding MAXXAM Lab Reference No. B Sample No. Location Description TCLP LEAD (mg/l) 3210EXT-TCLP Exterior Wood Siding Green Paint on Wood Siding 0.55 OTHER HAZARDS AND NOTES: None observed RISK ASSESSMENT AND RECOMMENDATIONS Prior to renovation or demolition activities, the hazardous materials identified in this report must be safely contained before disturbance. Depending on the areas to be renovated or demolished, Additional destructive sampling may be required to identify asbestos-containing materials that were not accessed during this targeted hazardous material sampling survey.
