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.

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)

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.

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 boundaries. The stormwater pipes at the Frontenac Farm were reported to be in poor condition. Two former quarries, later used as landfills, were located on the Frontenac Institution farmlands. The Phase I ESA also addressed hazardous waste generation, hazardous building materials, and other compliance issues associated with the developed portion of the Collins Bay Institution. These items are documented in the Phase I ESA report but are not anticipated to be associated with potential concerns for the Site.

Golder Associates Inc, 2010. Phase I Environmental Site Assessment, CORCAN Agribusiness Operations, Frontenac Correctional Institution, Correctional Service Canada, PWGSC Project Number R.037566.001.

Golder Associates Inc. (Golder) was retained by PWGSC and CSC to complete an enhanced Phase I and Preliminary Phase II ESA to support the decommissioning and closure of farm operations at the Frontenac Institution and CORCAN agribusiness. No activities were completed in support of a Preliminary Phase II ESA as a result of the frozen ground surface conditions.

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. A preliminary SAR assessment was also completed. From a search of nearby water well records, 169 water wells were identified within 1,500 metres of the property, with 11 water wells identified on the Frontenac Institution property. It was assumed that most of the wells were not in use due to the age of installation and the presence of a potable water source from the City of Kingston. Depth to groundwater was estimated to be between 0 – 5 metres below ground surface (m BGS) near Cataraqui Creek, with deeper groundwater in the vicinity of the Collins Bay Institution (15 – 25 m BGS). Overburden thickness was estimated to be between 0 to 3 m BGS. Several tributaries to the Little Cataraqui Creek Wetland Complex cross the property, with the nearest being located approximately 400 metres east of the Site and approximately 700 metres north of the Site. The property was identified to be flood-prone.

In the vicinity of the Site, pesticide use by CORCAN on crops (corn, hay) was identified as area of potential environmental concern (APEC) B-1. This was the only APEC identified for the Site. Reddendale Gas Bar, converted into a garage (King Street Auto Centre), was located at Front Road and Days Road, approximately 190 metres west of the Site. A transformer station, located off-Site, was identified approximately 390 metres east of the Site. An aerobic manure composting facility was identified (APEC B- 2) in the southeastern portion of the property, approximately 400 metres east of the Site. The lagoon has overflowed historically and discharged to Little Cataraqui Creek.

Two limestone quarries (Landfill Sites #1 and #2, APEC A-2 and A-3) were identified on the farmlands, located approximately 750 metres east and 1,200 metres north of the Site. These quarries were first observed in 1951 and were backfilled with fill and miscellaneous wastes between 1950 and 1990. Another small dumping area was identified off Quarry Road near Cataraqui Creek (approximately 850 metres northeast of the Site). This was identified as Landfill #3 (APEC A-4), and additional site assessment work in the vicinity of this landfill was completed between 2002 and 2006 to characterize the potential impact of this landfill on the surrounding area. Coal ash was noted to have been used in paved roads and parking lots near the institution property (APEC A-1); however, previous sampling had indicated that the fill and nearby groundwater met the applicable criteria.

The buildings comprising the Frontenac Institute were reported to have been constructed between 1943 and 1990, with agricultural land use prior to 1936. One building west of the Collins Bay Institution (located approximately 1,300 metres northeast of the Site) was reported to have been used for firefighter training. Crops, dairy and poultry operations were identified at the Collins Bay Institution, with a shop used for general maintenance and repair. Records for several underground and aboveground storage tanks were identified at the Frontenac Institute for the storage of diesel, furnace oil, and waste oil. Several of these storage tanks were identified to have been removed prior to the site visit. Two old liquid filled transformers with less than 2 parts per million of PCBs were also removed prior to the site visit. Numerous APECs were identified in association with the Frontenac Institute.

Golder, 2010. Phase II Environmental Site Assessment, CORCAN Agribusiness Operations, Correctional Service Canada, Frontenac Correctional Institution (441-F01), Kingston, Ontario.

Golder was retained by PWGSC and CSC to complete a Phase II ESA to support the decommissioning and closure of farm operations at the Frontenac Institution and CORCAN agribusiness, and to investigate the 20 APECs previously identified in the Enhanced Phase I ESA.

As part of the Phase II ESA, boreholes, groundwater monitoring wells, and test pits were advanced across the Frontenac Institute property, in addition to the collection of surface soil, sediment, and surface water samples. Samples were submitted to AGAT Laboratories for analysis of the relevant contaminants of potential concern, which included metals and inorganics, nutrients, biological oxygen demand (BOD), total dissolved solids (TDS), microbiology parameters, organochlorine pesticides and PCBs, petroleum hydrocarbon fractions one to four (PHC F1 – F4), benzene, toluene, ethylbenzene, and xylenes (BTEX), volatile organic compounds (VOCs), pH, organic content, and/ or grain size. Comparison was made to both federal and provincial guidelines and standards.

Based on the Phase II ESA activities, groundwater was inferred to flow towards the southeast, towards Little Cataraqui Creek and Lake Ontario. Fine-grained soil with varying amounts of silt and clay (i.e., silt clay, silty clay loam, clay, heavy clay) were identified, along with some sand and gravel fill near the farm buildings. Bedrock was encountered at around 4.5 m BGS, with the exception of one location with shallow bedrock (0.76 m BGS) in the northwest corner.

One borehole and monitoring well (B-1 BH/MW1) and two surface soil samples (B-1 SS2, B-1 SS3) were advanced to the north of the Site. The soil pH reported at each of these sampling locations ranged from 4.91 to 5.32 for shallow soil samples (0 to 0.6 m BGS). The depth to groundwater at the well located north of the Site was 2.22 m BGS. Exceedances of copper and selenium were identified at this groundwater well.

Nine additional boreholes with installed monitoring wells, one additional borehole, 13 test pits and 12 additional surface soil samples were collected from elsewhere on the Frontenac property. The depth to groundwater at the Frontenac property ranged from 0.60 m to 2.22 m BGS. Additional sediment and surface water samples were collected at other tributaries to Little Cataraqui Creek. Contamination of soil, groundwater, sediment, and surface water with various metals was observed at various other locations across the Frontenac Property, in addition to exceedances of applicable PHC guidelines and criteria in soil near former fuel storage locations at the farm buildings.

The Site was included as part of Contaminated Site (CS) #1, which includes the overall Frontenac Property excluding farm building areas, specifically with APEC B-1. CS #1 was given a National Classification System for Contaminated Sites (NCSCS) score of 58.2, or Class 2 priority. The other contaminated sites (CS #2 to CS #5) were located around farm buildings located within the Frontenac Institute. These contaminated sites all had NCSCS scores below 50, with Class 3 priority. The landfills and roadways were not investigated as part of this Phase II ESA.

Franz Environmental, 2011. Phase II Environmental Site Assessment, Frontenac Institution Former Landfill No. 2 (CSC-ID: 441-L01) and Adjacent Off-Site Sources (CSC-ID:441-C21a), Kingston, Ontario.

Franz Environmental (Franz) was retained by PWGSC and CSC to compete a Phase II ESA at former Landfill Site #2 and the adjacent northwest property, located approximately 1,200 metres north of the Site. The property is approximately 0.6 hectares (ha) and was reported to have been quarried for limestone in the 1930s while constructing Collins Bay Institution. It was backfilled with fill and waste of unknown quality. A former gas station including a gasoline underground storage tank and auto service shop were identified up-gradient at the northwest adjacent property.

Seven boreholes, with six completed as monitoring wells, were advanced within the footprint of the former landfill. Sandy silt and silty sand was identified up to 3.66 m BGS, underlain by silty clay and clayey silt until presumed bedrock. Fill material was identified at several locations. One monitoring well was advanced through bedrock from 1.22 m BGS to 9.45 m BGS. The depth to groundwater ranged from approximately 0.57 m BGS to 4.17 m BGS (in bedrock). The inferred direction of groundwater flow was to the southeast and east.

Soil and groundwater samples were submitted for laboratory analysis of metals, inorganics, VOCs, PHC F1 – F4, PAHS, PCBs and organochlorine pesticides. Concentrations of PAHs exceeding applicable guidelines or standards were noted at two boreholes within the footprint of the former landfill. Vertical and horizontal delineation was not achieved, but the volume of impacted soil was estimated to be approximately 13,420 cubic metres (m3). Elevated concentrations of iron, toluene, and PAHs in groundwater were detected, in addition to an exceedance of DDT at one monitoring well. The impacted groundwater was not delineated. Landfill Site #2 was defined as a Contaminated Site with a NCSCS score of 69, or Class 2 priority.

Two additional boreholes completed as monitoring wells were installed on the northwest adjacent property. Soil and groundwater samples were submitted for laboratory analysis of metals, inorganics, VOCs, PHC F1 – F4, PAHS, PCBs and organochlorine pesticides. Exceedances of chloride and mercury were identified in groundwater, which could be attributed to off-Site impacts. The northwest adjacent property was ranked with a NCSCS score of 46 and Class 3 priority.

AMEC, 2012. Phase III Environmental Site Assessment, Former Landfill 2 (441-L01), Frontenac Institution, Kingston, Ontario.

AMEC was retained by PGWSC and CSC to complete a Phase III ESA at former Landfill Site #2 to build on the work completed by Franz in 2011.

Fill placement was identified almost to the top of bedrock within the landfill footprint. The shallow groundwater was identified between 1 and 3.05 m BGS with an inferred direction of flow to the south/ southeast. Deep groundwater was identified between 3.90 and 7.99 m BGS, with a flow direction to the north/ northeast. Bedrock was considered to be a confining layer, with low hydraulic conductivity.

Twelve test pits were advanced to delineate fill placement, in addition to eight boreholes, with seven completed as monitoring wells. Soil and groundwater samples were collected and analysed for PAHs, organochlorine pesticides, PCBs, metals and inorganics.

Exceedances of PAHs in soil and groundwater were delineated within the footprint of the former landfill. Exceedances of iron, manganese, and selenium in groundwater were attributed to the landfill and delineated. Exceedances of chloride in groundwater exceeded the applicable guidelines and standards at all locations, which were linked to a potential off-Site source (roadways and de-icing salts). Exceedances of mercury, DDT, and organochlorine pesticides in groundwater were noted.

Exp, 2017. Human Health and Ecological Risk Assessment- CSC-ID: 441-L01 & 331-C21A (Landfill Site #2 & Adjacent Area (FCSI 0024663), Collins Bay Institution, Kingston, ON.

Exp was retained by PWGSC to complete a human health and ecological risk assessment of the former Landfill Site #2 and the adjacent northwest property. The risk assessment identified contaminants of potential concern associated with the property, defined receptors and exposure pathways, and evaluated the risks to suggest risk management measures.

Groundwater sampling was completed at the 15 existing monitoring wells. Exceedances of three PAHs in groundwater were identified at one location, and exceedances of boron, dissolved metals, and other inorganic parameters in groundwater were identified at several locations.

Potential human receptors at the property were identified as young adult to adult subsurface workers and federal personnel (maintenance or inmate), along with indirect exposure to the general public from cultivated crops. Potential pathways of human exposure included incidental ingestion, dermal absorption, outdoor inhalation, ingestion of produce/ vegetation, and contaminated breast milk. No human health risk was identified.

Potential ecological receptors of concern included the aquatic plant community, benthos community, terrestrial plants/ invertebrates, fish, muskrat, duck, loon, turtle, meadow vole, shrew, fox, mouse, grouse, barn swallow, peregrine falcon, robin, frog, and garter snake. Potential pathways for ecological exposure included direct contact with contaminated soil/ groundwater/ sediment/ surface water, ingestion of contaminated soil/ sediment/ surface water, and ingestion of prey. Several potential species at risk (SAR) were identified for the property: monarch butterfly, common nighthawk, short-eared owl, grey fox, snapping turtle, butternut, black term, Blanding’s turtle, spiny softshell turtle, northern map turtle, milksnake, and red-shouldered hawk. There is the potential for these SAR to be present at the Site as well. No ecological risk was identified.

The site closure tool (SCT) was completed for the former Landfill Site #2, and the property was concluded to be closed following the risk assessment. No future liability or monitoring was expected to be required.

Exp, 2018. Groundwater Monitoring Well Decommissioning and Monitoring Well Maintenance Letter Report.

Exp was retained by PSPC – Ontario Region to complete well repairs and decommission wells at Joyceville and Collins Bay Institutions in Kingston, Ontario. Fifteen monitoring wells were decommissioned at the Collins Bay institute. The PVC pipe was removed and bentonite chips were used to fill the holes. The SCT was updated to reflect the decommissioning.

Natural Resource Solutions Inc., 2019. Correctional Service Canada – Ontario Region Species at Risk Surveys, Final Report.

Natural Resource Solutions Inc. (NRSI) was retained by Correctional Service Canada (CSC) to conduct Species at Risk (SAR) surveys at 13 CSC properties in Ontario, including the Collins Bay Institution. SAR specific surveys were prepared to determine the presence or absence of all SAR known or suspected at the institutions, and species-specific recommendations were provided.

The SAR investigation at the Collins Bay Institute was combined with the Henry Trail Community Correctional Centre and completed between June 5, 2018 and May 16, 2019. Ten SAR were identified within the two properties, including the Kentucky Coffee-tree, Grasshopper Sparrow, Eastern Wood-Pewee, Bobolink, Bald Eagle, Barn Swallow, Snapping Turtle, Midland Painted Turtle, Western Chorus Frog, and Monarch. In addition, a River Bluet was identified, which is considered a species of conservation concern. The bats identified at these properties were considered common species throughout Ontario. Based on the map provided indicating the location of the observations of these SAR, no SAR observations were made within the Site area.

General recommendations from the report that were suggested to be implemented at all CSC properties included reducing the use of neonicotinoid pesticides, promoting healthy transition zones between natural habitat and agricultural fields, educating personnel regarding the potential SAR, and providing opportunities for personnel to share potential sightings or identification of any SAR.

FINDINGS OF RECORDS REVIEW

Based on the review of the above documents, the following APECs exist at the Site as follows:

• APEC1 – Entire Site (application of pesticides) • APEC2 – Entire Site (perfluoroalkyl substances (PFAS) related to fire training activities west of Collins Bay Institution and northeast of the Site)

Due to the elevated water solubility and environmental stability of PFAS, activities at the former fire training facility have the potential to impact the Site, despite the fact that the location of the facility could be considered to be cross-gradient from the Site.

Other potential sources of contamination, such as the transformer station, DuPont Chemical Plant, landfills and Reddendale Gas bar have been discounted from the APEC list above, as they are located in the inferred downgradient or cross-gradient direction or they are located too far away from the Site.

EXISTING SITE CONDITIONS

A summary of existing site conditions based on results from records review is provided below.

Land Use

The Site currently used for agricultural purposes, or the cultivation of crops. Stantec understands that the proposed future use is residential /institutional.

Surrounding Land Use

Surrounding land use is agricultural to the north and east, and recreational and residential to the south and west. Three former landfills are located on the adjacent property, approximately 750 metres east, 850 metres northeast, and 1,200 metres north of the Site. An aerobic composting facility is located 400 metres east of the Site. The Collins Bay Institution, with associated fuel storage and waste generation, is located approximately 1,300 metres northeast of the Site. Little Cataraqui Creek Wetland Complex is located 980 metres east of the Site. DuPont is located 230 metres east of the Site. Reddendale Gas Bar, also a garage, was located at Front Road and Days Road, approximately 190 metres west of the Site.

SAR Survey

Based on the SAR survey provided, no SAR were identified within the Site during the most recent SAR survey.

Site Buildings and Services

There are no buildings located on the Site. Groundwater is not used as a potable water supply for the Site. Drinking water is provided by the City of Kingston.

Underground Utilities

It is not anticipated that there are any underground utilities at the Site, but this should be verified through public and private utility locates. If utilities are present, they may act as a preferential pathway.

Subsurface Soils

The surficial geology in the vicinity of the Site is described as glaciomarine deposits of silt and clay (Barnett et al., 1991).

The soil profile in the vicinity of the Site was generally reported to consist of fine-grained soils (varying degrees of silt and clay) to bedrock surface.

Bedrock

Bedrock outcrops consisting of limestone, dolostone, shale, arkose, and sandstone sequences of the Ottawa Group, Simcoe Group, Shadow Lake are reported in the vicinity of the Site (Ontario Geological Survey, 2011). Bedrock on the Site was not encountered at depths up to 5.03 m BGS, but was identified between 0.76 and 4.5 m BGS elsewhere on the Collins Bay Institute property.

September 30, 2019 Ms. Barbara Slezak Page 10

Reference: Data Gap Analysis for Site 2 – Possible Road Access to NTA, Collins Bay Institute, Kingston, Ontario (ON)

Topography

The Collins Bay Institute property is situated near the shores of Lake Ontario. The approximate elevation of the property is about 80 metres above sea level (masl). The property is fairly flat, sloping slightly towards Little Cataraqui Creek and Lake Ontario. The property has been reported to be flood-prone.

Anticipated Groundwater Flow Direction

The depth to groundwater just north of the Site has been reported to be approximately 2.22 m BGS. From previous environmental assessment activities at the property, the inferred direction of groundwater flow is towards the southeast and east, towards Little Cataraqui Creek and Lake Ontario.

Ground Cover

The Site is currently used for the cultivation of crops and has historically been used for agricultural purposes. There are no records of imported fill material for the Site.

Contaminants

Historical results of soil and groundwater sampling in the vicinity of the Site have been compared to the current applicable regulatory criteria and guidelines for the Site. The locations of the historical samples are shown on Figure 3, in Attachment A, and the results are summarized in Tables 1 and 2, in Attachment B.

No exceedances of BTEX, PHC F1 – F4, metals, or pesticides were observed in the soil samples collected near the Site. However, the pH measured in the soil samples was out of the acceptable CCME range. Grain size analysis identified heavy clay from 2.44 to 3.05 m BGS. In groundwater, exceedances of copper and selenium were observed in comparison with the applicable FIGQG. Several pesticides had guidelines below the provided laboratory reporting limits.

Based on historical land use at the Site and surrounding properties, the contaminants of potential concern (COPCs) in soil are pesticides and PFAS. The COPCs in groundwater are metals, pesticides and PFAS.

DATA GAP ANALYSIS

Following Stantec’s review of historical reports, several data gaps were identified. The following sections presents a summary of data gaps, by media, identified for each APEC along with recommended follow-up actions to address each gap.

The data gaps were developed for a government-owned site using residential land-use, non-potable groundwater and fine-grained soil. If site conditions change, the results of the previous assessments should be re-evaluated to ensure that there are no additional or increased risks to potential receptors, on- or off-the Site. It is Stantec’s assumption that there is no current groundwater use for potable drinking water at the Site and that the future NTA will be connected to the municipal water supply system. Prior to any future use of groundwater for potable drinking water or other human use (e.g., showering, washing), the groundwater should be analysed to demonstrate that groundwater quality is within Health Canada’s Guidelines for Canadian Drinking Water Quality.

Reference: Data Gap Analysis for Site 2 – Possible Road Access to NTA, Collins Bay Institute, Kingston, Ontario (ON)

SOIL

Based on the absence of soil sampling locations on the Site, Stantec recommends that soil sampling as part of a Phase II ESA be conducted to assess the presence of the COPCs in soil.

GROUNDWATER

Based on the absence of groundwater sampling locations on the Site, Stantec recommends that groundwater sampling as part of a Phase II ESA be conducted to assess the presence of the COPCs in groundwater.

SURFACE WATER

Based on a review of the available information, it is not expected that there are any surface water bodies located on the Site.

SEDIMENT

Based on a review of the available information, it is not expected that there is any sediment associated with surface water bodies on the Site.

RECOMMENDATIONS

Stantec recommends that a Phase II ESA be conducted at the Site to assess the APECs identified. This would include the advancement of four boreholes to be completed as monitoring wells. Soil and groundwater samples would be submitted from each location for the COPCs (pesticides and PFAS) as well as parameters that will inform soil management during the planned redevelopment, including metals, PHCs, VOCs and PAHs analysis, with in situ hydraulic conductivity testing completed in up to three newly installed monitoring wells on the Site. Dependent on the results of the Phase II ESA, a Phase III ESA or Risk Assessment may be required.

Further, the results of the soil and groundwater sampling completed as part of the Phase II ESA should be incorporated into a Soil and Groundwater Management Plan, with an emphasis on the development area. The soil management portion of the plan will include a summary of soil quality and would provide recommendations for the following: 1) re-use of contaminated soil at the Site; 2) management of excess soils, including identification of appropriate waste facilities; 3) importation of clean fill, if applicable. The plan would also include detailed figures to graphically represent soil quality and disposal options. The groundwater management portion of the plan would include a summary of available background information, site specific stratigraphy from historical geotechnical investigations (if available), groundwater quality results, hydraulic conductivity results, an estimate of maximum and average daily dewatering rates, and a recommendation regarding the need for a permit to take water (PTTW), if required.

Stantec’s opinion of probable cost to carry out this Phase II ESA program and prepare a Soil and Groundwater Management Plan is $40,076.00 excluding applicable taxes. The opinion of probable cost includes consultant and subcontractor costs for the completion of the environmental work program and reporting and is based on Stantec’s experience on similar projects. A detailed cost breakdown is provided in Attachment C.

Stantec made the following assumptions in the development of the opinion of probable cost:

• Costs are based on Stantec 2019 SOA rates and are subject to change based on bidding Consultant rates. • Phase II ESA fieldwork will be completed by one person and consists of four days of fieldwork. • Travel costs are based on four return trips to the Site and accommodation costs are based on one overnight in Kingston, ON. • Soil and groundwater samples will be submitted for laboratory analysis on regular turnaround time. • One consolidated set of comments will be received prior to submission of the final report.

In addition to the Phase II ESA and Soil and Groundwater Management Plan, Stantec recommends consultation with the City of Kingston to confirm what studies are required to support future development at the Site, specifically, to determine if a Site Plan Control Application to the City of Kingston Planning Department is required as part of the building permit process. At this point, Stantec does not consider that an updated Phase I ESA is required. If a Site Plan Control Application is required, the Phase II ESA may be sufficient to satisfy the City of Kingston.

The recommendations above consider next steps to facilitate construction at the Site from an environmental perspective. Stantec recommends completing a preliminary geotechnical assessment of the Site concurrent with any environmental investigation to obtain required information on the physical properties of soil and bedrock at the Site and to inform building and foundation design for proposed redevelopment.

CLOSURE/LIMITATIONS

This report documents work that was performed in accordance with generally accepted professional standards at the time and location in which the services were provided. No other representations, warranties or guarantees are made concerning the accuracy or completeness of the data or conclusions contained within this report, including no assurance that this work has uncovered all potential liabilities associated with the identified property.

This report provides an evaluation of selected environmental conditions associated with the identified portion of the property that was assessed at the time the work was conducted and is based on information obtained by and/or provided to Stantec at that time. There are no assurances regarding the accuracy and completeness of this information. All information received from the client or third parties in the preparation of this report has been assumed by Stantec to be correct. Stantec assumes no responsibility for any deficiency or inaccuracy in information received from others.

The opinions in this report can only be relied upon as they relate to the condition of the portion of the identified property that was assessed at the time the work was conducted. Activities at the property subsequent to Stantec’s assessment may have significantly altered the property’s condition. Stantec cannot comment on other areas of the property that were not assessed.

Conclusions made within this report consist of Stantec’s professional opinion as of the time of the writing of this report and are based solely on the scope of work described in the report, the limited data available and the results of the work. They are not a certification of the property’s environmental condition. This report should not be construed as legal advice.

This report has been prepared for the exclusive use of the client identified herein and any use by any third party is prohibited. Stantec assumes no responsibility for losses, damages, liabilities or claims, howsoever arising, from third party use of this report.

The locations of any utilities, buildings and structures, and property boundaries illustrated in or described within this report, if any, including pole lines, conduits, water mains, sewers and other surface or sub- surface utilities and structures are not guaranteed. Before starting work, the exact location of all such utilities and structures should be confirmed and Stantec assumes no liability for damage to them.

The conclusions are based on the site conditions encountered by Stantec at the time the work was performed at the specific testing and/or sampling locations, and conditions may vary among sampling locations. Factors such as areas of potential concern identified in previous studies, site conditions (e.g., utilities) and cost may have constrained the sampling locations used in this assessment. In addition, analysis has been carried out for only a limited number of chemical parameters, and it should not be inferred that other chemical species are not present. Due to the nature of the investigation and the limited data available, Stantec does not warrant against undiscovered environmental liabilities nor that the sampling results are indicative of the condition of the entire site. As the purpose of this report is to identify site conditions which may pose an environmental risk; the identification of non-environmental risks to structures or people on the site is beyond the scope of this assessment.

Should additional information become available which differs significantly from our understanding of conditions presented in this report, Stantec specifically disclaims any responsibility to update the conclusions in this report.

This report was prepared by Janice Cooper, M.Sc., EIT., Jacqueline Gillis, B.Sc., P.Eng. and reviewed by Jill Peters-Dechman, P.Eng., and Jane Yaraskavitch, M.Eng. P.Eng.

c,STB,LTG Hardness dependent guideline; if hardness of receiving surface water is available can be calculated as 10exp{0.83(log[hardness])-2.46} / The short-term benchmark concentration of 1.0 µg·L-1 is for waters of 50 mg CaCO3·L-1 hardness. The short-term benchmark for cadmium is related to water hardness (as CaCO3): When the water hardness is 0 to < 5.3 mg/L, the short-term benchmark is 0.11 μg/L, At hardness ≥ 5.3 to ≤ 360 mg/L, the short-term benchmark is calculated using this equation (Short-term benchmark (μg/L) = 10{1.016(log[hardness]) – 1.71 }); At hardness > 360 mg/L, the short-term benchmark is 7.7 μg/L. / The CWQG for cadmium (i.e. long-term guideline) of 0.09 µg·L-1 is for waters of 50 mg CaCO3·L-1 hardness. The CWQG for cadmium is related to water hardness (as CaCO3): At hardness ≥ 17 to ≤ 280 mg/L, the CWQG is calculated using this equation (CWQG (μg/L) = 10{0.83(log[hardness]) – 2.46 }); At hardness > 280 mg/L, the CWQG is 0.37 μg/L.

e Guideline is the lowest of all applicable pathways.

e,d,TBC1 Guideline is the lowest of all applicable pathways. / The freshwater aquatic life guidelines vary depending on water pH, hardness etc. Therefore, see Canadian Water Quality Guidelines for the Protection of Aquatic Life (CCME 1999) to determine the appropriate water quality guideline applicable to the site and calculate the groundwater guidelines using formulas provided in Appendix B. / Value is minumum value available.
