(AECOM) was retained by the Toronto Transit Commission (TTC) to complete a screening of contaminated sites for the properties along Leslie Street, between Commissioners Street and Queen Street East, and along Queen Street East between Curzon Street and Hastings Avenue (Figures 1 and 2) (hereafter referred to as “the Extended Study Area”) in association with the Light Rail Vehicle (LRV) Fleet Replacement Yard Environmental Assessment being completed for the Extended Study Area and the north portion of the Ashbridges Bay Treatment Plant (ABTP), which is detailed in a Phase I Environmental Assessment under separate cover. The combined length of the Extended Study Area is approximately one kilometre (0.64 miles). The Extended Study Area properties are owned and maintained independently and the roadways in the Extended Study Area are owned and maintained by the City of Toronto. The purpose of the Contaminated Sites Screening Report is to identify actual and potential sources of contamination associated with the properties along the Extended Study Area arising from documented current and/or historic activities on the Property and the neighbouring properties prior to the development of the LRV Fleet Replacement Yard and associated connecting tracks in the Extended Study Area. A review of historical records including aerial photographs, MOE databases, city directories, topographic and soil maps, fire insurance maps, and EcoLog ERIS records was performed and a site visit of the Extended Study Area was conducted on October 15, 2009 to observe existing property conditions from publically accessible right-of-ways. Summary of Findings and Conclusions: Several potential environmental concerns were identified in the Extended Study Area. Historical records indicated that several service
