Stantec Consulting Ltd. 400 - 1331 Clyde Avenue, Ottawa ON K2C 3G4 September 30, 2019 File: 122170330 Attention: Ms. Barbara Slezak Senior Environmental Specialist, Environmental Services and Contaminated Sites Public Works and Government Services Canada 4900 Yonge Street Toronto ON M2N 6A6 Dear Ms. Slezak, Reference: Data Gap Analysis for Site 2 – Possible Road Access to NTA, Collins Bay Institute, Kingston, Ontario (ON) INTRODUCTION Stantec Consulting Ltd. (Stantec) was retained by Public Works and Government Services Canada (PWGSC), on behalf of Correctional Services Canada (CSC), to complete a data gap analysis in support of future construction of a National Training Academy (NTA) at the Collins Bay Institute in Kingston, Ontario (ON). A parcel of land is being considered for construction of a possible access road to the NTA in the southwestern corner of the much larger Collins Bay Institute property, herein referred to as the Site. Figures 1 and 2, in Attachment A, present the location of the Site and relevant surrounding features. The requirements of the project are detailed in the Statement of Work for Data Gap Analysis at Collins Bay Institution (SOW), dated July 9, 2019, along with Stantec’s proposal, dated July 15, 2019. This report presents the findings of the Historical Report Review and Data Gap Analysis for the Site. BACKGROUND The Collins Bay Institute is located in Kingston, Ontario and is bordered by Bath Road (north), Days Road (west), Front Road (south) and Little Cataraqui Creek (east). The property comprises approximately 340 hectares (ha) and is shared between the Collins Bay Medium and Maximum Institution (formerly the Collins Bay and Frontenac Correctional Institution), and CORCAN Agribusiness Operations. Dairy and poultry operations, in addition to the cultivation of crops have been conducted on the property. Construction of the Collins Bay Institution began in 1935 and continued until 1995. Farm buildings associated with CORCAN were constructed prior to 1968. Three former landfills were reported to have been located on the Collins Bay Institute property. The Site is approximately 6 ha and is located at the southwestern corner of the property, near the intersection of Days Road and Front Road, and adjacent to a curling club and arena. The Site has historically been used for agricultural purposes. September 30, 2019 Ms. Barbara Slezak Page 2 Reference: Data Gap Analysis for Site 2 – Possible Road Access to NTA, Collins Bay Institute, Kingston, Ontario (ON) OBJECTIVES The overall purpose of the gap analysis is to review existing environmental site assessment and risk assessment reports pertaining to the Collins Bay Institute to summarize relevant information pertaining to the Site. Based on the historical report review, data gaps relating to the environmental condition of soil and groundwater on the Site will be identified. Relevant historical analytical data will be compared to guidelines reflecting the proposed land use of the Site. Should data gaps be identified, recommendations for additional sampling and a cost estimate will be provided to address gaps in consideration of future development at the Site. SCOPE OF WORK To meet the initial objective (i.e., identify data gaps), the scope of work included the following: • Review previous reports and other pertinent information related to the Site • Tabulate and compare historical analytical data from the Site to guidelines applicable for the proposed land use (i.e., residential and institutional), if applicable • Conduct a data gap analysis and, if applicable, identify areas of the Site that require further data and evaluation to support development of the Site • Summarize the Records Review and Data Gap Analysis process in this report Costing information in support of the recommended future work has been included in Attachment C. CURRENT REGULATORY FRAMEWORK Although no historical sampling has been completed on the Site, the applicable regulatory framework to evaluate and compare soil and groundwater quality data include the following: Soil • Canadian Council of Ministers of the Environment (CCME) Canadian Soil Quality Guidelines for the Protection of Environmental and Human Health (CCME online) • CCME Canada Wide Standards for PHCs in Soil, Table 2, Tier 1, 2001, as revised in 2008 • Ministry of Environment, Conservation and Parks (MECP) Soil, Ground Water and Sediment Standards for Use Under Part XV.1 of the Environmental Protection Act, Table 3 Full Depth Generic Site Condition Standards (SCS), 2011 (used in the absence of federal criteria) Groundwater • Federal Interim Groundwater Quality Guidelines (FIGQG) for Federal Contaminated Sites, 2016 • MECP Soil, Ground Water and Sediment Standards for Use Under Part XV.1 of the Environmental Protection Act, Table 3 Full Depth Generic SCS, 2011 (used in the absence of federal criteria) Based on the site conditions, standards for residential/ institutional land use, medium to fine textured soil, and non-potable groundwater are considered applicable.

Summaries of previous environmental investigations are provided below. SNC Lavalin Engineers & Constructors Inc., 1999. Phase I Environmental Site Assessment, Collins Bay Institution. SNC Lavalin Engineers & Constructors Inc. (SNC) was retained by PWGSC and CSC to complete a Phase I Environmental Site Assessment (ESA) for the Collins Bay Institute, as part of a baseline environmental assessment (EA) for 12 other federal correctional institutions in Ontario. The Phase I ESA was conducted to identify areas of potential contamination on the Collins Bay Institution property. As part of the Phase I ESA, a review of relevant environmental records (i.e., aerial photographs, land title documents, fire insurance plans, etc.) was completed, in addition to interviews and a site visit. The topography of the Collins Bay Institute property was described as fairly flat, sloping slightly towards Lake Ontario and local creeks. Some limestone outcrops were identified, and overburden in the area was described as clayey soils. Potable water at the property is supplied by the City of Kingston. The Little Cataraqui Creek Wetland Complex (Class 1, Provincially Significant Wetland) was identified adjacent to the east of the property (approximately 980 metres east of the Site). The areas surrounding the property to the north, west, and south were generally described as commercial or residential. A DuPont chemical plant was identified south of the property, across Front Road. September 30, 2019 Ms. Barbara Slezak Page 4 Reference: Data Gap Analysis for Site 2 – Possible Road Access to NTA, Collins Bay Institute, Kingston, Ontario (ON) In the vicinity of the Site, historical use was identified as agricultural. Parts of Lot 9, which was indicated to be on the western side of the property, were briefly owned by Canadian Petrofina Ltd. The exact location of this lot within the Collins Bay Institute, and with respect to the Site, was not clearly indicated. An arena was identified at the intersection of Days Road and Front Road, adjacent to the west of the Site. The DuPont chemical plant is located approximately 230 metres east of the Site. This property was developed in the 1950s and included various storage tanks and PCB waste storage. The bulk of the Phase I ESA was focused on the developed portion of the Collins Bay Institution, located approximately 1,300 metres northeast of the Site. The 40 buildings comprising the Collins Bay Institute were constructed between 1935 and 1995. Potentially contaminating activities at the Collins Bay Institution included a paint booth, automotive repair, power plant, and a health care centre. Several underground and aboveground tanks for fuel oil, diesel, gasoline, and waste oil were located within the institution
