Colliers International 13 SLR Ref.: 210.05696.00 Phase I ESA February 17, 2009 5515 Clyde Street & 1452 Queen Street, Halifax, NS 5.13 Pesticides It is unlikely that pesticides are used on the subject properties as they are used as parking lots. Given the current and historical land use, it is unlikely that significant pesticide use would have been undertaken at the subject property. 5.14 Tanks and Other Oil Company Infrastructures 5.14.1 Aboveground Tanks Nova Scotia Environmental Registry documents reviewed did not provide any evidence of ASTs on the subject properties or surrounding properties presently or in the past; however fill/vent pipes were observed on the exterior of the multi-unit residential dwelling on the east side of the Queen Street parking lot. This indicates that a fuel oil AST is likely present inside the building. 5.14.2 Underground Tanks There are no known underground tanks located on the subject properties or on the adjacent properties. A search of the Nova Scotia Environment Environmental Registry did not return any documentation of registered tanks on the subject property or properties immediately adjacent. Documents related to underground tanks returned from the Registry search are provided in Section 4.2.3. 5.15 Spills or Presence of Stains/Odours No spills, stains or odours were observed on the subject properties at the time of site inspection. 5.16 Impacts on Environment and Natural Receptors Several catch basins were observed on and around the subject property at the time of site investigation. It is unlikely that any potential contamination on surrounding properties be associated with the subject property. SLR
Colliers International 14 SLR Ref.: 210.05696.00 Phase I ESA February 17, 2009 5515 Clyde Street & 1452 Queen Street, Halifax, NS 6.0 CONCLUSIONS SLR has performed a Phase I ESA in conformance with the scope and limitations of the CSA Standard Z768-01 and Halifax Regional Municipality’s Request for Proposal (HRM RFP) #08- 359 of the properties located at 5515 Clyde Street and 1452 Queen Street in Halifax, Nova Scotia. There were no exceptions to or deletions from the CSA Standard Z768-01. Based on the results of the Phase I ESA, SLR identified the following potential environmental concerns associated with the subject property: • A laundromat/dry cleaner is located across Clyde Street, southeast of the site. • 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. • Several pole-mounted transformers are located around the subject property on Dresden Row, Clyde Street and Birmingham Street. • A small pay station building is located on the west side of each parking lot. Each building contains a small Danby air conditioner. • Minor spills and leaks from vehicles may impact the subsurface via the cracks observed in the parking lots. • A laundromat was formerly located in the southwest corner of one of the subject properties (1452 Queen Street). • Former buildings located on each of the subject properties were demolished and buried on-site. • Several former service stations were located on surrounding properties and could potentially impact the subject properties. • 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. • Acid-generating bedrock may be present on this site.
