1891 & 1931 ROBERTSON ROAD, OTTAWA, ONTARIO FINAL REPORT PHASE I ENVIRONMENTAL SITE ASSESSMENT PREPARED FOR: BELLS CORNERS PROPERTIES LTD. E&W REF: 614678 Submitted: September 6, 2013 Prepared by: SNC-Lavalin Inc. Environment & Water Ottawa, Ontario Phase I Environmental Site Assessment 1891 & 1931 Robertson Road, Ottawa, Ontario EXECUTIVE SUMMARY SNC-Lavalin Inc., Environment & Water (E&W) was retained by Bells Corners Properties Ltd. (BCP) to conduct a Phase I Environmental Site Assessment (ESA) and review of historical information for the property located at 1891 and 1931 Robertson Road in Ottawa (Bells Corners), Ontario; specifically, Part 4 of Lot 12 Concession 2 (Ottawa Front) (herein referred to as the “site”). The site is owned by BCP, comprises approximately 4.7 hectares, and is occupied by two (2) buildings (Buildings No. 1 and 4). An assessment of the on-site buildings was not included within this Phase I ESA. To meet the objectives described above, E&W developed a scope of work which included the following tasks: 1) Review of Historical and Regulatory Records; 2) Site Visit; 3) Interview(s); and, 4) Evaluation of Information and Reporting. There was no historical information pertaining to significant environmental concerns (e.g. spills or leaks) on the property and no issues were identified during the site inspection or interviews. A previous property assessment (AEI, 1995) investigated the location of the former fuel oil tank located immediately east of Building No. 1. AEI reportedly found “Trace to low level diesel range organic impacts were identified in the former heating oil USTs which serviced Buildings No. 1 and 2”. Soil samples from a borehole drilled through the boiler room floor had no discernable evidence of impact. Based on the results of this Phase I ESA, the highest risk to the subject property is presented by off-site sources of contamination. In particular high volume users of hazardous materials (e.g. retail fuel outlets) located up-gradient from the subject property represent the highest potential to impact the subject property. The risk is mitigated by the presence of large sequences of low permeability clay which underlie the site, and restrict the potential movement of groundwater plumes.

INTRODUCTION SNC-Lavalin Inc., Environment & Water (E&W) was retained by Bells Corners Properties Ltd. (BCP) to conduct a Phase I Environmental Site Assessment (ESA) and review of historical information for the property located at 1891 and 1931 Robertson Road in Ottawa (Bells Corners), Ontario; specifically, Part 4 of Lot 12 Concession 2 (Ottawa Front) (herein referred to as the “site”). The site is owned by BCP, comprises approximately 4.7 hectares, and is occupied by two (2) buildings (Buildings No. 1 and 4). An assessment of the on-site buildings was not included within this Phase I ESA. This report documents the methodology and findings of the Phase I ESA. All work was completed in accordance with the E&W proposal to Bells Corners Properties Ltd. dated July 25, 2013. Historical information for the Phase I ESA was gathered from August to September 2013. Site visits were completed on September 2, 2013. 1.1 Objective and Scope of Work The objectives of the Phase I ESA were to identify and evaluate any existing or potential environmental concerns at the site. The Phase I ESA was completed based on the Canadian Standards Association (CSA) Standard Z768-01 Phase I ESA (CSA, 2001; reaffirmed 2012), subject to the following study limitations: • No on-site infrastructure was assessed; • No potential for vapour intrusion was assessed; • No soil, water, building materials or other samples were collected or analysed as part of this work program; and, • Inspections of surrounding properties were limited to visual observations from accessible portions of the site and from publicly accessible vantage points. To meet the objectives described above, E&W developed a scope of work which included the following tasks: 1) Review of Historical and Regulatory Records; 2) Site Visit; 3) Interview(s); and, 4) Evaluation of Information and Reporting.
