February 2017 REPORT ON Phase One Environmental Site Assessment 258 Carruthers Avenue Ottawa, Ontario Submitted to: 258-262 Carruthers APTS Ltd. 5689 Power Road Ottawa, Ontario K1G 3N4 Report Number: 1671453-1000 Rev.0 Distribution: 1 e-copy - 258-262 Carruthers APTS Ltd. REPORT 1 copy - 258-262 Carruthers APTS Ltd. 1 e-copy - Golder Associates Ltd. PHASE ONE ESA – 258 CARRUTHERS AVENUE OTTAWA, ONTARIO Executive Summary The Executive Summary highlights key points from the report only; for complete information and findings, as well as the limitations, the reader should examine the complete report. Golder Associates Ltd. (Golder) was retained by 258-262 Carruthers APTS Ltd. (“Carruthers”) to conduct a Phase One Environmental Site Assessment (“Phase One ESA”) of the property located at 258 Carruthers Avenue in Ottawa, Ontario (herein after referred to as the “Site” or “Phase One Property”) as shown on Figures 1 and 2. At the time of the Site reconnaissance, which was conducted on January 11, 2017, the Site consisted of a 540 m2 (0.05 hectare) parcel of residential land occupied by a two-storey residential building, a single storey residential building, a paved driveway and a snow covered front yard. It is understood that the Phase One Property is to be redeveloped with a four-storey residential building with one basement level. The Phase One ESA was completed in general accordance with Ontario Regulation (O. Reg. 153/04), as amended, and included a review of available current and historical information regarding the Site and surrounding properties, a Site reconnaissance, interviews, evaluation of readily available information, and reporting, subject to the limitations outlined in Section 9.0 of this report. Given that the Site is currently developed as a residential property and has not been used as an automotive garage, a bulk liquid dispensing facility or a dry cleaning facility, the Site is not considered an enhanced investigation property as defined by O. Reg. 153/04. There is no change in land use proposed; therefore the Phase One ESA has not been completed to support a Record of Site Condition. Based on the information obtained as part of this Phase One ESA, none of the identified potentially contaminating activities (PCAs) were considered to represent an area of potential environmental concern (APEC) for the Site and a Phase Two ESA is not recommended to be carried out at the Site at this time. However, the following building–related issues of potential environmental concern were identified: Based on the age of the on-Site buildings (1948 to 1956), potential ACMs such as floor tiles, dry wall compounds, stucco ceilings, plaster and window caulking may be present in the on-Site buildings; and, Based on the age of the on-Site buildings (1948 to 1956), there is a potential for lead- containing materials, such as paints, to be present in the buildings. Prior to renovations or demolition of the building, ACMs must be removed in accordance with Ontario Regulation 278/05: Designated Substance - Asbestos on Construction Projects and in Buildings and Repair Operations. Other designated substances must be removed or managed in accordance within the OH&S Act. At the time of preparation of this report, a response to Golder’s request for information had not been received from the Ministry of Natural Resources and Forestry. In addition, Golder was unable to access the smaller residential building located on the southwest corner of the Site during the Site visit. However, based on the body of information acquired, it is considered that the absence of this information should not likely affect the final conclusion of the Phase One ESA. Golder will review the response from the Ministry of Natural Resources upon its receipt and should the response affect the findings of this Phase One ESA, it will be forwarded to the Client. There were no material deviations to the Phase One ESA requirements set out in O.Reg. 153/04 that would cause uncertainty or absence of information that would affect the validity of the Phase One Conceptual Site Model or the findings of this Phase One ESA.
