Colliers International 11 SLR Ref.: 210.05696.00 Phase I ESA February 17, 2009 5515 Clyde Street & 1452 Queen Street, Halifax, NS 5.5 Asbestos-Containing Materials Most asbestos containing building materials were phased out in the 1980s. However, ACMs can be found in buildings constructed as late as 1990 (Environment Canada, 2005). One of the main problems with asbestos comes from sprayed or "friable" (easily broken up) amphibole asbestos used in buildings until the 1970s. People working in construction, maintenance or renovation of older buildings should be particularly careful when handling this asbestos. Items such as floor tiles, ceiling tiles/panel, pipe and pipe elbow wrap, wallboard, and shingles, may contain ACMs. The regulations governing the handling and disposal of ACMs are located in the Nova Scotia Environment Act, Asbestos Waste Management Regulations, N.S. Reg. 53/95 Due to the age of the buildings, it is possible that ACM may be present. Health risks associated with exposure to ACMs is considered low, as long as the suspected ACM containing material remains in good condition. Caution should be taken during regular maintenance in the vicinity of potential ACMs to prevent the potential ACMs from becoming damaged. Sampling of potential asbestos-containing materials should be completed prior to any site renovations or demolition. 5.6 Polychlorinated Biphenyls (PCBs) From the 1930s to the 1970s, PCBs were used to make coolants and lubricants for certain kinds of electrical equipment, including transformers and capacitors, and were widely used in a number of industrial materials including sealing and caulking compounds, inks, and paint additives. PCBs are an environmental concern as they do not readily degrade and have been identified as bioaccumulative. In Canada, the federal Environmental Contaminants Act (1976) prohibited the use of PCBs in heat transfer and electrical equipment installed after September 1, 1977, and in transformers and capacitors installed after July 1, 1980. In addition, the storage and disposal of PCB waste materials is regulated. Several pole-mounted transformers were observed during the site reconnaissance. These units or their predecessors may contain PCBs; however, no leaks were noted. 5.7 Lead Based Paint Under the federal Hazardous Products Act, the lead content in interior paint was limited to 0.5% by weight in 1976. After 1980, lead was not used in interior paints; however, exterior paints may have still contained lead. All consumer paints produced and imported into Canada were virtually lead-free as of 1992. There is one small building on each of the subject properties, as well as a multi-unit residential dwelling on the Queen Street property. Due to the age of the buildings, lead-based paint may have been used. SLR
Colliers International 12 SLR Ref.: 210.05696.00 Phase I ESA February 17, 2009 5515 Clyde Street & 1452 Queen Street, Halifax, NS 5.8 Ozone-Depleting Substances Ozone-depleting substances are generally found in equipment such as air conditioners, refrigerators and freezers. Both pay station buildings on the subject properties house small air conditioners; other ozone depleting substances are also assumed to be present in the multi-unit dwelling. Ozone-depleting substances could pose environmental concern for the subject property. 5.9 Mercury No mercury-containing instruments or appliances were observed at the time of site reconnaissance. The buildings on the subject properties should be inspected for any appliance or instrument containing mercury prior to their demolition. Any mercury encountered must be properly disposed. 5.10 Radioactive Material No radioactive materials were observed during the subject property reconnaissance. 5.11 Backfilling Materials No documentation regarding excavation of the subject property was available for review by SLR; however, during discussions with site personnel it was discovered that former buildings on each property were demolished and the debris was buried on-site. If any building debris is encountered during excavation, it should be tested for regulated materials to determine proper disposal procedures. 5.12 Radon “Radon (Rn-222), a radioactive gas associated with an increased incidence of lung cancer, is formed by the natural radioactive decay of uranium. Geological mapping of rocks and soils with a potential for high uranium content can be used to interpret regional variations in the concentration of radon in homes. Because of its effects on human health, radon is considered a potential "geochemical hazard" where it occurs at high concentrations.” (Geological Survey of Canada: Environmental geochemistry and geochemical hazards – Radon. R.D. Knight and R.A. Klassen) Based on a uranium map of Nova Scotia, it was determined that the subject property is in an area with moderate uranium content, however uranium mapping alone can not predict corresponding radon concentration in buildings. No radon testing was completed as part of this assessment. SLR
