Prepare plans and performance specifications for hazardous material removal required for the planned work. The specifications should include the scope of work, safe work practices, personal protective equipment, respiratory protection, and disposal of waste materials. 2. Investigate any items excluded from the scope of work of this report. Ideally this investigation will be performed as part of the development of the specifications, or at a minimum immediately prior to commencing renovations when the areas are no longer occupied. Specifically the following materials/areas need to be investigated: Susbstation Switch Yard Basement Vault Room 808 due to no access at the time of this assessment. Oil containing electrical equipment, when de-energized 3. Provide this report and the detailed plans and specifications to the contractor prior to bidding or commencing work Pinchin West Ltd. Page 10 of 14

17 4. Retain a qualified consultant to specify, inspect and verify the successful removal of hazardous materials. 5. Update the asbestos inventory upon completion of the abatement and removal of asbestos-containing materials. 4.2 Building Demolition or Renovation Work The following recommendations are made regarding demolition or renovation involving the hazardous materials identified Asbestos Remove all asbestos-containing materials (ACM) prior to renovation, alteration, maintenance or demolition work 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. Asbestos-containing materials 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. Items painted with paints containing elevated levels of lead may be a hazardous waste. Test lead-painted materials for leachable lead and other metals prior to disposal. Well adhered paints containing elevated levels of lead on metal substrates do not require leachable lead analysis as the materials can be recycled with the paint intact. Lead-containing items (lead-acid batteries, lead cables) should be recycled when taken out of service or prior to building demolition 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 2016 Pinchin West Ltd. Page 11 of 14

18 containing silica should be completed only with proper respiratory protection and other worker safety precautions that comply with provincial standards or guidelines Mercury Do not break lamps. Recycle and reclaim mercury from fluorescent lamps when taken out of service PCBs When light fixtures are removed, examine light ballasts for PCB content. If ballasts are not clearly labelled as non-pcb, or are suspected to contain PCBs; package and ship ballasts for destruction at a federally permitted facility. Liquid in electrical equipment and cables should be sampled immediately for classification purposes. PCB liquids are a hazardous waste. When PCB containing electrical equipment has been decommissioned package and ship for destruction at a federally permitted facility Mould No mould was observed; if mould is uncovered inside wall cavities during hand demolition, use appropriate precautions and protect workers using methods that comply with provincial guidelines Radioactive Materials Reclaim radioactive materials from fire detection systems when taken out of service. Use appropriate precautions and protect workers using methods that comply with provincial and federal guidelines Animal Carcasses and Droppings Disturbance and clean-up of animal carcasses and droppings should be conducted only with proper precautions, protecting workers using methods that comply with Regulation 6.34 of the Occupational Health and Safety Regulations Heavy Metals Copper items (copper jacketing and copper cables) should be recycled when taken out of service or prior to building demolition Flammable Materials Handling of controlled products, including flammable materials should be conducted following appropriate worker safety precautions that comply with provincial standards or guidelines Pinchin West Ltd.

29 APPENDIX III Methodology

30 Cargill Grain Terminal, Methodology Document 1.0 GENERAL PWL conducts a room-by-room survey (rooms, corridors, service areas, exterior, etc.) to identify the hazardous building materials as defined by the scope of work. All work is conducted in accordance with our own internal Standard Operating Procedures. Information regarding the location and condition of hazardous building materials encountered and visually estimated quantities are recorded. The locations of any samples collected are recorded on small-scale plans. As-built drawings and previous reports are referenced where provided. 1.1 Scope Limitations The assessment excludes the following: Articles belonging to the owner, tenant or occupant (e.g. stored items, furniture, appliances, etc.); Underground materials or equipment (e.g. vessels, drums, underground storage tanks, pipes, etc.); Building envelope, structural components, inaccessible or concealed materials or other items where sampling may cause consequential damage to the property. 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.). In occupied facilities, PWL only undertakes non-intrusive testing. Concealed spaces such as those above solid ceilings and within shafts and pipe chases are accessed via existing access panels only. PWL does not conduct demolition of walls, solid ceilings, structural items, interior finishes or exterior building finishes, to determine the presence of concealed materials. 1.2 Asbestos PWL 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 Pinchin Ltd. Page 1 of 5

31 Cargill Grain Terminal, Methodology Document 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 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 material. The homogeneous materials are determined by visual examination and available information on the phases of construction and prior renovations. PWL 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. PWL undertakes sampling of roofing felts at the client s request. A temporary repair is made with asphaltbased 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. PWL 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). If present, the following materials are presumed to be asbestos-containing and are best sampled immediately prior to commencing renovation/disturbance: roofing, felts and tar concrete floor levelling compound elevator and lift brakes electrical components or wiring within control centers, breakers, motors or lights, insulation on wiring refractory materials and insulations in boilers, incinerators and stacks insulation under metal clad boilers and vessels vermiculite in concrete block wall cavities fibre reinforced paints and coatings mechanical packing, ropes and gaskets fire resistant doors or metal clad finishes 2016 Pinchin Ltd.

32 Cargill Grain Terminal, Methodology Document exterior cladding PWL submits the bulk samples to a NVLAP 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 In British Columbia an ACM is defined as materials containing 0.5% asbestos by weight, or any amount of asbestos for vermiculite insulation. The asbestos analysis is completed using a stop positive approach. Only one result meeting the above regulated criteria 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 equal to or 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, this means that either no asbestos was detected by the analytical method utilized in any of the multiple samples or, if detected, it is below the lower limit of an asbestos-containing material in the applicable regulation. 1.3 Lead PWL collects samples of distinctive paint finishes and surface coatings present in more than a limited application, where removal of the paint is possible. PWL collects samples by scraping the painted finish to include base and covering applications. Drawings included show sample locations. Analysis for lead in paints or surface coatings is performed at an accredited laboratory in accordance with EPA Method No. 3050B/Method No. 7420; flame atomic absorption. For this report, all paints containing lead at a concentration of 0.009% or greater are discussed. Paint and surface coatings are evaluated for condition such as flaking, chipping or chalking. Other lead building products (e.g. batteries, lead sheeting, flashing) are identified by visual observation only. 1.4 Silica PWL 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. PWL does not perform sampling of these materials for laboratory analysis of crystalline silica content Pinchin Ltd. Page 3 of 5

33 Cargill Grain Terminal, Methodology Document 1.5 Mercury Building materials/products/equipment (e.g. thermostats, barometers, pressure gauges, light tubes), suspected to contain mercury are identified by visual inspection only. Dismantling of equipment suspected of containing mercury is not performed. Sampling of these materials for laboratory analysis of mercury content is not performed. Mercury spills or damaged mercury-containing equipment are recorded where observed. 1.6 Polychlorinated Biphenyls PWL determines the potential for light ballasts and oil containing electrical equipment 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. PWL records spills or leakage of suspect PCB-containing fluids where observed or identified in historical documents. PWL samples exterior caulking or sealants for PCBs based on the date of construction or installation. Caulking installed after 1985 is presumed to be free of PCBs and hence not sampled. If sampled, analysis for PCBs is performed using an ASTM test method appropriate to the sample matrix at an accredited laboratory. 1.7 Ozone Depleting Substances (ODS) PWL determines the potential presence of ODS (chlorofluorocarbon, hydrochlorofluorocarbon, hydrofluorocarbon, halon, etc.) in air conditioning units, chillers, commercial coolers and fire suppression systems by visual inspection of manufactures labels or plates, maintenance records, or log books, etc. Domestic type equipment such as window mounted and small central air conditioners, refrigerators, and freezers are not evaluated for the presence of ODS. 1.8 Visible Mould PWL 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. 1.9 Stored Chemicals (Explosive Materials, Flammable Materials, Household Chemicals) A visual inspection is conducted to identify any stored chemicals (solvents, cleaners, paints, compressed gas, etc.). Quantities and contents were inventoried where possible Pinchin Ltd. Page 4 of 5

34 Cargill Grain Terminal, Methodology Document 1.10 Animal Carcasses and Droppings PWL identifies the presence of animal droppings and carcasses if visibly present in a significant quantity on exposed building surfaces. If any animal droppings and carcasses are concealed within wall cavities it is not addressed in this assessment. Locations were inventoried where possible Needles and Sharps PWL conducts a visual inspection to identify visible needles and or sharps. Locations were inventoried where possible Radioactive Materials PWL conducts a visual inspection to identify equipment that may contain radioactive materials Heavy Metals PWL conducts a visual inspection to identify equipment and materials, as well as industrial processes that contain or use heavy metals.
