Colliers International Phase I ESA - 5515 Clyde St 1452 Queen St, Halifax, NS ii SLR Project Ref No. 210.05696.00 February, 2009 Potential Environmental Concerns VOCs • Dry cleaning operations are often responsible for the introduction of VOCs into the environment. A laundromat/dry cleaner is located across the street from the subject properties. A laundromat was formerly located in the southwest corner of the Queen Street property. Regulated Building Materials • Due to the age of the buildings, it is possible that the multi-unit residential dwelling and the pay stations buildings may contain regulated building materials. Prior to building demolition, a Regulated Building Materials Survey should be completed to assess the potential health risks for construction workers during demolition and to determine disposal options of the materials PCB-Containing Materials • There are several pole-mounted transformers on the streets surrounding the subject properties. No leaks were noted, however regular inspections should be conducted. Ozone-Depleting Substances (ODSs) • The pay stations on both subject properties house small air conditioners that are likely to contain ODSs. The units should be inspected prior to their removal and any hazardous materials must be property disposed. Petroleum Leaks • The subject properties are currently in use as public parking lots and are therefore susceptible to impacts caused by vehicular leaks or spills. Past Site Uses • Former buildings on the subject properties were demolished and buried onsite. If any building materials are uncovered during site excavations, they must be tested for regulated materials to determine proper disposal. • Several service stations were formerly located in the general area of the subject properties. Impacts due to historic service station activity may still be present on-site. Radon • The subject property is in an area that is mapped as having moderate uranium content. The decay of uranium produces radon gas that is harmful to human health. Testing for indoor radon gas should be conducted in existing buildings and considered in the design of any future buildings. Bedrock • Acid-generating bedrock could be present on this site. Future development at the site should address potential acid-generating issues. Executive Summary continued on next page . . . SLR
