Repair approximately twenty square feet of the damaged, lead-containing, off-white paint on the ceiling in the 2 nd Floor Back Exit following Type 2a lead abatement procedures. 2. Prepare plans and specifications for hazardous material removal which will or may be affected by the planned work or is otherwise scheduled for removal. The specifications should include and address the scope of work, safe work practices, personal protective equipment, respiratory protection, and disposal of waste materials. 3. Investigate any items excluded from the scope of work of this report. Ideally this investigation will be performed immediately prior to commencing renovations when the areas are no longer occupied. 4. Provide this report and the detailed plans and specifications to the contractor prior to bidding or commencing work. 5. Retain a qualified consultant to specify, inspect and verify the successful removal of hazardous materials. 6. Update the asbestos inventory upon completion of the abatement and removal of ACM. 4.2 Building Demolition or Renovation Work The following recommendations are made regarding demolition or renovation involving the hazardous materials identified Pinchin LeBlanc Environmental Limited Page 8 of 11

14 Chebucto Road, Halifax, Nova Scotia Pinchin File: Green Stem Housing Co-operative FINAL Asbestos Remove all ACM prior to renovation, alteration, maintenance or demolition work or if ACM may be disturbed by the work. If the identified ACM will not be removed prior to commencement of the work, disturbance of ACM must follow the appropriate asbestos precautions for the classification of work being performed. Follow Type 2 asbestos abatement procedures for scheduled removal of the textured ceiling finish. Follow Type 1 asbestos abatement procedures for scheduled removal of the black tar on sink. ACM must be disposed of at a landfill approved to accept asbestos waste Lead Construction disturbance of lead in paint and coatings (or other materials) may result in over-exposure to lead dust or fumes. The need for work procedures, engineering controls and personal protective equipment will need to be assessed on a project-by-project basis and must comply with provincial standards or guidelines. Performing an exposure assessment during work that disturbs lead in paints and coatings may be able to alleviate the use of some of the precautions specified by these standards or guidelines. Lead-painted items may be a hazardous waste. Test lead-painted materials for leachable lead prior to disposal Silica Construction disturbance of silica-containing products may result in excessive exposures to airborne silica, especially if performed indoors and dry. Cutting, grinding, drilling or demolition of materials containing silica should be completed only with proper respiratory protection and other worker safety precautions that comply with provincial standards or guidelines Mercury Construction disturbance of mercury in paint and coatings (or other materials) may result in overexposure to mercury. The need for work procedures, engineering controls and personal protective equipment will need to be assessed on a project-by-project basis and must comply with provincial standards or guidelines. Mercury-painted items may be a hazardous waste. Test mercury-painted materials for leachable mercury prior to disposal Pinchin LeBlanc Environmental Limited Page 9 of 11

32 APPENDIX II Methodology

33 Green Stem Housing Co-operative Pinchin File: Methodology Appendix II 1.0 GENERAL Pinchin conducts a room-by-room assessment (rooms, corridors, service areas, exterior, etc.) to identify the hazardous building materials as defined by the scope. Information regarding the approximate quantity, location, and condition of hazardous building materials encountered and visually estimated quantities are recorded. 1.1 Limitations on Scope The assessment excludes the following: Owner or occupant articles (e.g. stored items, furniture, appliances, etc.); Underground materials or equipment (e.g. vessels, drums, underground storage tanks, pipes, etc.); Energized systems (e.g. internal boiler components, elevators, mechanical or electrical components); Controlled products (e.g. stored chemicals, operational or process-related substances); and Materials not typically associated with construction (e.g. settled dust, spills, residual contamination from prior spills, etc.). The assessment includes limited demolition of wall and ceiling finishes (drywall or plaster) to view concealed conditions at representative areas as permitted by the current building use. Limited destructive testing of flooring is conducted where possible (under carpets or multiple layers of flooring). Demolition of masonry walls (chases, shafts etc.), structural items or exterior building finishes is not conducted. 1.2 Asbestos Pinchin conducts an inspection for the presence of friable and non-friable asbestos-containing materials (ACM). A friable material is a material that when dry can be crumbled, pulverized or powdered by hand pressure. A separate set of samples is collected of each type of homogenous material suspected to contain asbestos. A homogenous material is defined by the US EPA 1 as material that is uniform in texture and appearance, was installed at one time, and is unlikely to consist of more than one type or formulation of 1 Environmental Protection Agency 2017 Pinchin LeBlanc Environmental Limited Page 1 of 4

34 Green Stem Housing Co-operative Pinchin File: Methodology Appendix II material. The homogeneous materials are determined by visual examination, available information on the phases of the construction and prior renovations. Pinchin collects samples at a rate that is in compliance with the requirements of local regulations and guidelines. The sampling strategy is also based on known ban dates and phase out dates of the use of asbestos; sampling of certain building materials is not conducted after specific construction dates. In addition, to be conservative, several years past these dates are added to account for some uncertainty in the exact start/finish date of construction and associated usage of ACM. In some cases, manufactured products such as asbestos cement pipe are visually identified without sample confirmation. Pinchin undertakes sampling of roofing felts at the client s request. A temporary repair is made with asphalt-based mastic and fibreglass mesh. A more permanent repair is required if the roofing or the building is to remain in use for any extended period of time. Pinchin is not responsible or liable for leaks or water damage caused by sampling and or repair. Flooring mastic/adhesive and leveling compounds are only sampled and analyzed if present on the underside of flooring samples (vinyl floor tile and vinyl sheet flooring). Pinchin submits the bulk samples to a NVLAP 2 accredited laboratory for analysis. The analysis is performed in accordance with Test Method EPA/600/R-93/116: Method for the Determination of Asbestos in Bulk Building Materials, July The asbestos analysis is completed using a stop positive approach. Only one result of greater than the regulated criteria (0.5%) is required to determine that a material is asbestos-containing, but all samples must be analyzed to conclusively determine that a material is non-asbestos. The laboratory stops analyzing samples from a homogeneous material once a result greater than the regulated criteria is detected in any of the samples of that material. All samples of a homogeneous material are analyzed if no asbestos is detected. In some cases, all samples are analyzed in the sample set regardless of result. Where building materials are described in the report as non-asbestos, or described as containing no asbestos, this is subject to the limitations of the analytical method used, and should be understood to mean no asbestos was detected. Asbestos materials are evaluated in order to make recommendations regarding remedial work. This includes friability, condition and efficiency and practicality of the work. 2 National Voluntary Laboratory Accreditation Program 2017 Pinchin LeBlanc Environmental Limited Page 2 of 4

35 Green Stem Housing Co-operative Pinchin File: Methodology Appendix II 1.3 Lead Pinchin collects samples of distinctive paint finishes and surface coatings present in more than a limited application, where removal of the paint is possible. Pinchin collects samples by scraping the painted finish to include base and covering applications. Analysis for lead in paints or surface coatings is performed in accordance with EPA Method No. 3050B/Method No. 7420; flame atomic absorption at an accredited laboratory. For this report, all paints containing lead at a concentration above the reportable detection limit (RDL) are discussed. Paint and surface coatings are evaluated for condition. Lead building products (e.g. batteries, lead sheeting, flashing) are identified by visual observation only. 1.4 Silica Pinchin identifies building materials suspected of containing crystalline silica (e.g. concrete, cement, tile, brick, masonry, mortar) by knowledge of current and historic applications and visual inspection only. Pinchin does not perform sampling of these materials for laboratory analysis of crystalline silica content. 1.5 Mercury Building materials/products/equipment (e.g. thermostats, barometers, pressure gauges, light tubes), suspected to contain mercury were identified by visually inspection only. Dismantling of equipment suspected of containing mercury was not performed. Sampling of these materials for laboratory analysis of mercury content was not performed. Analysis for mercury in paints or surface coatings is performed in accordance with EPA Method No & SM 3112B; flame atomic absorption at an accredited laboratory. For this report, all paints containing mercury at a concentration above the reportable detection limit (RDL) are discussed. Paint and surface coatings are evaluated for condition. 1.6 Polychlorinated Biphenyls Pinchin determines the potential for light ballast and wet transformers to contain PCBs based on the age of the building, a review of maintenance records and examination of labels or nameplates on equipment, where present and accessible. The information is compared to known ban dates of PCBs and Environment Canada publications. Dry type transformers are presumed to be free of dielectric fluids and hence non-pcb. Pinchin records spills or leakage of suspect PCB-containing fluids where observed or identified in historical documents Pinchin LeBlanc Environmental Limited Page 3 of 4

36 Green Stem Housing Co-operative Pinchin File: Methodology Appendix II Fluids (mineral oil, hydraulic or Askaral) in transformers or other equipment are not sampled for PCB content. 1.7 Visible Mould Pinchin identifies the presence of mould if visibly present in a significant quantity on exposed building surfaces. If any mould growth is concealed within wall cavities it is not addressed in this assessment Pinchin LeBlanc Environmental Limited Page 4 of 4
