3 Executive Summary Pinchin Environmental Ltd. (Pinchin) was retained by CB Richard Ellis Management Services (CBRE) to conduct a Limited Environmental Site Assessment, Designated Substance, and Mould Investigation of the property located at Pitt Street & Second Street, Cornwall, Ontario, Canada (hereafter referred to as the Site). The Site is developed with a Canadian Imperial Bank of Commerce (CIBC) banking branch (Transit No. #00442). The following are the significant findings: 1. The Site covers an area of approximately 5300 square feet and is developed within a multistorey building with a footprint of approximately 11,000 square feet. The remaining areas at the lot consist of concrete walkways. The Site is bounded by Second Street to the south, Pitt Street to the east, and commercial buildings to the north and west, and parking and residential units to the north. 2. The building consists of a steel structure, slab on grade, with plaster walls, and flat roof system. Exterior finishes consist of metal fascia and soffit, metal and aluminium framed windows and doors, and concrete block walls. Interior finishes consist of ceiling tiles, drywall, plaster, concrete block, ceramic tiles, vinyl floor tiles, terrazzo, and carpet. The branch is cooled by a roof top unit via ducts throughout the upper ceiling space. 3. Housekeeping was GOOD at the time of the assessment with the exception of dirt and debris in the janitor s closet. 4. Ozone depleting substances may be present in the roof top HVAC unit, the refrigerator, and the water cooler in the branch. 5. Friable ACMs identified include chrysotile asbestos-containing parging cement pipe insulation was observed on pipe fittings in the men s washroom and in the janitor s closet in the basement. Chrysotile asbestos-containing mag block pipe insulation was observed on pipe straights in the men s washroom and in the janitor s closet in the basement. No proactive removal is required at this time. 6. Non-friable ACMs identified include 12 x 12 vinyl floor tiles in the vaults on the main level, the server room in the basement, the kitchen in the basement, and the corridor in the basement. All vinyl floor tiles were in GOOD condition at the time of the assessment. No pro-active removal is required at this time. 7. Paints with regulated amounts of lead were not identified in the branch. Lead is suspected to be present in batteries associated with emergency lighting systems, in solder on copper piping, in bell and spigot joints, and in the glazing of ceramic tiles throughout the branch. 8. Mercury vapour may be present inside fluorescent light fixtures and thermostats. Tubes should be removed intact prior to removing the fixtures. Liquid mercury may also be present inside thermostats, thermometers, and manometers in mechanical equipment. 9. It is suspected that some of the fluorescent lamp ballasts may contain PCBs.

4 10. Minor water staining was observed on the drywall wall in the janitor s closet in the basement of the branch. Suspect mould staining was not observed in any locations throughout the building during the investigation. Existing conditions within the Branch at the time of survey do not require any immediate disruption of Branch operations nor the removal of occupants from the building. However, Pinchin recommends the following to enhance CIBC s compliance with current regulations as well as proactive health and safety and environmental management. The following are the significant recommendations of the report: 1. Inform all contractors performing renovations within the branch of the presence of designated substances. 2. Following general housekeeping procedures, perform a general cleaning of the janitor s closet. 3. Continue to manage ozone depleting substances in compliance with applicable regulations (if present). 4. Any removal of asbestos-containing pipe and duct insulation will require Type 2 asbestos precautions for minor removal (<1 m 2 ) and Type 3 asbestos precautions for major removal (> 1 m 2 ). Type 2 Glove bag asbestos precautions may be used depending on site conditions and geometry of piping. No pro-active removal is required at this time. 5. Any removal of asbestos-containing vinyl floor tiles due to demolition, renovation, etc, will require Type 1 procedures as outlined by Ontario Regulation 278/05. Use only hand-held non-powered tools and wetting if breakage occurs. No pro-active removal is required at this time. 6. Any disturbance or removal of suspect lead containing building equipment or finishes will require appropriate lead abatement precautions or engineering controls to prevent the creation of lead dust. No pro-active removal is required at this time. 7. Prior to removal of fluorescent light fixtures, the tubes should be removed from the fixtures intact to prevent the mercury vapour from escaping. As long as the tubes are not broken, workers will not be exposed to hazardous mercury vapour. If applicable, mercury should be collected from thermostats, thermometers and manometers prior to demolition. 8. When fluorescent light fixtures are removed from service, examine the ballasts within the fixtures for determination of PCB content. If ballasts are suspected to contain PCBs, handle in accordance with Regulation R.R.O. 1990/362. In order to comply with environmental regulations and to protect workers, fluorescent tubes should not purposely be broken. Instead, when old tubes are removed they should be held in protective packaging and either disposed of as hazardous waste or be removed off-site by a licensed contractor for recycling.

5 9. Following Canadian Construction Association Level I mould procedures, remove, dispose of, and replace all water damaged and water stained drywall around the sink in the janitor s closet.

7 Environmental Assessment June 19, 2006 Pitt St. & Second St., Cornwall, Ontario CIBC Transit Pinchin Project: PURPOSE Pinchin Environmental Ltd. (Pinchin) was retained by CB Richard Ellis Management Services (CBRE) to conduct a Limited Environmental Site Assessment, Designated Substance, and Mould Investigation of the property located at Pitt Street & Second Street, Cornwall, Ontario, Canada (hereafter referred to as the Site). The Site is developed with a Canadian Imperial Bank of Commerce (CIBC) banking branch (Transit No. #00442). The purpose of this report is to provide the Client with documentation that highlights areas of potential concern regarding environmental liabilities and non-compliance with current regulations related to designated substances, chemical use, waste management, and mould at the Site. The scope of work, methodology, and regulatory requirements for this project are outlined in the Overview Report, dated May 2005 by Pinchin. There were no deviations from the methodology or scope described in the Overview Report. Only reportable items are discussed. If there was no evidence of a potential environmental issue being present at the site, then it is not addressed in the report. For example, if no storage tanks were noted on the site, then these items are not discussed in the report. 2.0 SITE DESCRIPTION 2.1 Site Location and Setting The Site is located within a multi-storey commercial building erected in 1945 on the corner of Pitt Street and Second Street, in Cornwall, Ontario (see Key Map, Appendix I). The Site is bounded by the streets and/or properties identified below: Direction North South East West Type of Property Use or Organization Commercial buildings. Second Street, beyond which is a parking lot. Pitt Street, beyond which are commercial buildings. Commercial buildings. Pinchin Environmental Ltd. Page 1

8 Environmental Assessment June 19, 2006 Pitt St. & Second St., Cornwall, Ontario CIBC Transit Pinchin Project: Site Physical Features The Site covers an area of approximately 5300 square feet and is developed within a multistorey building with a footprint of approximately 11,000 square feet. The remaining areas at the lot consist of concrete walkways. 2.3 Property Use, Building and Site Description The building consists of a steel structure, slab on grade, with plaster walls and flat roof system. Exterior finishes consist of metal fascia and soffit, metal and aluminium framed windows and doors, and concrete block walls. Interior finishes consist of ceiling tiles, drywall, plaster, concrete block, ceramic tiles, vinyl floor tiles, terrazzo, and carpet. The branch is heated and cooled by a roof top unit via ducts throughout the upper ceiling space. Drawings of the subject building are presented in Appendix II. The following municipal services are provided to the Site: community well, storm and sanitary sewers, and electricity. The topography of the Site appears to slope slightly to the south. It is inferred that groundwater on the Site would generally flow in the same direction towards the St. Lawrence River. It should be noted, however, that the direction of groundwater flow can be influenced by the presence of underground utilities and underground building structures. Specifically, the gravel backfill around utilities, such as storm sewers, can act as an interceptor and redirect groundwater flow along the direction of the pipe. A subsurface investigation would be required if a more accurate description of groundwater flow and quality is needed. 3.0 LIMITED ENVIRONMENTAL SITE ASSESSMENT Abby Barclay of Pinchin conducted a Site inspection on March 22, Additional sample collection and investigation was performed on May 8, 2006 to confirm sampling results and extent of asbestos containing materials. At the time of the initial Site inspection, the ground was dry, weather conditions were overcast, outdoor temperature and relative humidity were approximately -5ºC and 68% respectively. The Site inspection included a review of all accessible areas of the branch including electrical rooms and mechanical rooms and spaces. The roof was not accessible for inspection.

9 Environmental Assessment June 19, 2006 Pitt St. & Second St., Cornwall, Ontario CIBC Transit Pinchin Project: of the building and grounds were inspected for visual evidence of potential environmental concerns. A selected photographic record of the Site visit is presented in Appendix IV. 3.1 On-Site Use of Chemicals and Hazardous Materials Small quantities of domestic cleaning solutions were observed in the janitor s closet. These solutions were observed to be stored in manufacturer supplied containers. The janitor s closet was dirty and disarrayed. 3.2 Waste Management Activities The wastes produced are typical of an office environment. Paper is shredded and removed from Site by Shred-It on a monthly basis. Bee Clean performs janitorial services for the branch on a daily basis, with waste removal performed nightly. Housekeeping is good throughout most areas with the exception of minor debris and dirt in the janitor s closet (Photo 1). No other liquid or hazardous wastes were observed at the Site. 3.3 Water and Wastewater Water is supplied to the Site by the city of Cornwall. Wastewater discharges consist of domestic water to municipal sanitary sewers and rainwater to municipal storm sewers. 3.4 Ozone-Depleting Substances Phase-out schedules exist at both the provincial and federal levels for eliminating the production and use of ozone-depleting substances (ODSs) in Canada. The Federal Ozone-Depleting Substances Regulation No. 1 includes a timetable for the reduced supply of specific ODSs, including the common refrigerants CFC-11 and CFC-12. Depending on supply, alternative refrigerants and equipment may be required. The use of halon-containing equipment for the purpose of fighting fires is not prohibited by the Ozone-Depleting Substances Regulation. One refrigerator and one water cooler were present on Site. These units were newer and likely do not contain ODSs. One rooftop HVAC unit (RTU) was present on Site. It is possible that the RTU may contain ODSs. 3.5 Radon Radon gas is a product of the natural decay series that begins with uranium. Radon is produced directly from radium, which can commonly be found in geological units that Pinchin Environmental Ltd. Page 3

10 Environmental Assessment June 19, 2006 Pitt St. & Second St., Cornwall, Ontario CIBC Transit Pinchin Project: contain black shale and/or granite. Radon gas can migrate through the ground and enter buildings through porous concrete or fractures. Radon tends to accumulate in poorly ventilated basements and confined areas. Based on the local geology and the fact that the site was constructed on grade, radon is not considered to be an issue at this Site. 3.6 Activities on Adjacent Properties There were no obvious indications of environmental concern noted on the adjacent properties; however, a thorough review of adjacent premises was not within the scope of this report. 4.0 DESIGNATED SUBSTANCES & POLYCHLORINATED BIPHENYL (PCB) INVESTIGATION 4.1 Asbestos-Containing Materials (ACMs) Asbestos laboratory test results are presented in Appendix III Friable ACMs Pipe, Duct, and Mechanical Insulations Parging cement insulation on pipe elbows in the men s washroom (approximately 2 fittings) and in the janitor s closet (approximately 12 fittings) in the basement was sampled and found to contain 60% chrysotile asbestos (Sample numbers 08-A/B/C). Samples 08-B and 08-C were not analyzed due to the stop positive method. This material was in GOOD condition at the time of the assessment. Mag block insulation on straight piping in the men s washroom (approximately 20 linear feet) and in the janitor s closet (approximately 50 linear feet) in the basement was sampled and found to contain 40% chrysotile asbestos (Sample numbers 03-A/B/C). Samples 03-B and 03-C were not analyzed due to the stop positive method. This material was in GOOD condition at the time of the assessment. Pipes and ducts in all other visually accessible locations throughout the building were either un-insulated or insulated with fibreglass. All mechanical equipment in the basement mechanical rooms was either un-insulated or insulated with fibreglass (i.e., boiler, breeching, air handling unit, hot water tanks, etc.) Pinchin Environmental Ltd.
