6 1 EXECUTIVE SUMMARY The Environment & Water business unit of SNCLavalin Inc. (SNCLavalin) was retained by the City of Ottawa (the City) to conduct a Phase Two Environmental Site Assessment (ESA) for the portion of the City s property located at 1951 Cyrville Road in Ottawa, Ontario that is proposed for the future development as a fire station. Field work activities were completed between December 15, 2015 and January 8, The objective of the Phase Two ESA work program was to evaluate soil and groundwater conditions relative to the area that is proposed for the future development as a fire station. The investigation included characterization of potential impacts to soil and groundwater within the Phase Two Property related to Areas of Potential Environmental Concern (APECs) from onsite sources and their associated Potential Contaminants of Concern (PCOCs) as identified in the Phase One ESA for the property at 1951 Cyrville Road (SNCLavalin, 2015). Identified APECs include historic backfilling at the site with fill of unknown source and/or quality, seasonal use for street sweepings dewatering and periodic use for outdoor storage/stockpiling of emulsified asphalt. Associated PCOCs include petroleum hydrocarbons (F1F4 PHCs), volatile organic compounds (VOCs) including benzene, toluene, ethylbenzene and xylenes (BTEX), polycyclic aromatic hydrocarbons (PAHs), metals, sodium adsorption ratio (SAR), and electrical conductivity (EC). Based on the results of the Phase Two ESA investigation, concentrations of PCOCs, including F1F4 PHC, VOCs, PAHs, metals and/or salinity parameters, exceed MOECC standards in soil and/or groundwater samples collected from the site. Overall, soil and groundwater quality at the site are considered to be poor. Buried wastes are present throughout the soil (fill) to maximum depths ranging from approximately to 4 to 5 m bgs. Numerous soil contaminants were detected sporadically in the soil. There do not appear be specific point sources of soil contamination; rather, impacts appear to be associated with unpredictable variations in the quality of the fill. The groundwater shows evidence of road salt impacts, and isolated impacts by PAHs (likely from associated soil impacts) and chloroform (likely related to municipal water discharges in the street sweeper dewatering area or, less likely, the historical chloramine spill near the northwest corner of the site). Soil and groundwater impacts were not fully delineated during the current Phase Two ESA. Based on the results and conclusions of the current investigation, the following recommendations are offered with respect to proposed future development of the site as a fire station: Contaminated soil and groundwater in the proposed development area should either be remediated to applicable MOECC site conditions standards or be assessed relative to potential human health and ecological risks. o Soil remediation would require excavation and offsite disposal of soil at a licensed landfill facility. Groundwater remediation could likely be largely accomplished during soil remediation by concurrent removal of water entrained in the soil and excavation Phase Two Environmental Site Assessment 1951 Cyrville Road, Ottawa, ON 24/03/ City of Ottawa Final Report SNCLavalin Inc All rights reserved Confidential 1

7 dewatering. Assuming all soil in the proposed development area (approximately 6,000 m 2 ) would require remediation to a depth of approximately 4 m (i.e. 24,000 m 3 of soil), the estimated cost for remediation is approximately $6,000,000. o Human health and ecological risk assessments could be conducted to evaluate the risks of developing the site as a fire station while leaving soil and groundwater impacts in place. Given that full delineation of contaminants has not been achieved, a RSCcompliant risk assessment cannot presently be completed. Rather, only a limited due diligence risk assessment is possible. The risk assessment would identify site specific target levels or "acceptable" concentrations of contaminants based on sitespecific conditions for the proposed property use as a fire station. The risk assessment may also propose risk management actions, if deemed necessary (e.g. limited soil remediation, contaminated soil capping, methane monitoring, etc.). The estimated cost for a due diligence risk assessment and risk management plan is approximately $25,000. A soil management plan should be developed for all excavation/soil generation activities at the site. The plan should recognize the limited potential for reuse of excavated soil due to the presence of wastes and exceedances of MOECC Table 1 standards. It is anticipated that virtually all soil generated during construction activities would need to be disposed offsite at a licensed landfill. The plan should also consider the guidance provided in the MOECC's (2014) document "Management of Excess Soil A Guide for Best Management Practices". A groundwater management plan should also be developed if excavations below the water table are anticipated. The plan should evaluate whether a MOECC Permit to Take Water (PTTW) would be required (note that changes to the PTTW may be enacted by the MOECC in 2016, and these should be considered in the plan). The plan should also consider whether water treatment will be required (e.g. sediment removal, etc.) and whether environmental compliance approvals (ECAs) or sewer use agreements would be required for water discharge. The estimated cost for a combined soil and groundwater management plan providing general guidance with respect to management of excess materials generated during construction is approximately $3,500.

8 2 INTRODUCTION SNCLavalin was retained by the City to conduct a Phase Two Environmental Site Assessment (ESA) for the portion of the City s property located at 1951 Cyrville Road in Ottawa, Ontario that is proposed for the future development as a fire station (herein referred as the Site or the Phase Two Property). Field work activities were completed between December 15, 2015 and January 8, SITE DESCRIPTION The site is located at the southern extent of Cyrville Road (Figure 1). The Phase Two ESA was conducted for the portion of the property proposed for future development as shown in Figure 2. Municipal Address 1951 Cyrville Road, Ottawa, Ontario Legal Description Part of Lot 22, CON 3 (OF), Gloucester, Gloucester Part 5 on 5R2265 except Part 24 on 5R5281 Property Identifier Number (PIN) Approximate Size (Phase Two Property) Approximately 1.7 acres (0.7 ha) A legal survey showing the limits of the Phase Two Property has not been completed. The limits of the Phase Two Property were established based on the footprint of proposed future development. 2.2 PROPERTY OWNERSHIP Site Owner Person requesting Phase Two ESA City of Ottawa David Kiar Advisor, Environmental Remediation Disposals & Environmental Remediation Unit Realty Initiatives & Development Branch City of Ottawa, Real Estate Partnerships & Development Office 5 th Floor, 110 Laurier Avenue West, Ottawa, Ontario K1P 1J1 2.3 CURRENT AND PROPOSED FUTURE USES The property is currently operating as a Municipal Works Yard. Redevelopment of the site as a fire station has been proposed. As the current plans for the fire station do not include living spaces that would be considered residential (as defined by O. Reg. 153/04), both property uses would be considered commercial/industrial and it is not anticipated that redevelopment would require filing of a Record of Site Condition (RSC).

9 2.4 APPLICABLE SITE CONDITION STANDARDS Site condition standards for use at the Phase Two Property were selected from the Ontario Ministry of the Environment and Climate Change (MOECC) "Soil, Ground Water and Sediment Standards for Use Under Part XV.1 of the Environmental Protection Act" (MOECC, 2011) using the approach described by Ontario Regulation 153/04 (as amended). The following site specific information was used to select standards for the Phase Two Property: Portions of the Phase Two Property would be considered environmentally sensitive areas (as defined by Section 41 of O. Reg. 153/04) because: o Green s Creek has been identified as an area of natural significance and is located immediately adjacent to the north of the Phase Two Property. As geographic boundaries of the area of natural significance are not fully delineated, the area of natural significance has been interpreted to include both Green s Creek and its surrounding undeveloped valley lands. o Portions of the Phase Two Property located more than 30 m from any identified areas of natural significance have not been considered as environmentally sensitive because the ph of surface soil is within the 5 to 9 range and subsurface soil is within the 5 to 11 range (Appendix A). The Phase Two Property is not a shallow soil property since more than 2/3 of the site has at least 2 m of soil cover. A water body (as defined by O. Reg. 153/04) is present immediately adjacent to the north of the Phase Two Property (i.e. Green s Creek). The full depth restoration option is being considered. Restoration of groundwater to potable levels is not required because: o The Phase Two Property, and all other developed properties located, in whole or in part, within 250 m of the boundaries of the site, are supplied by a municipal drinkingwater system as defined in the Safe Drinking Water Act, 2002 (supply source: Ottawa River) and no active wells (as defined in O. Reg. 153/04) have been confirmed to be in use within 250 m; o The property is not located within an area designated as a wellhead protection area (or equivalent); o The land is not used for agricultural or other use (as defined by O. Reg. 153/04); and, o The City of Ottawa (singletier municipality) has confirmed a nonpotable groundwater condition at the site. Based on current operations at the Phase Two Property (Municipal Works Yard) property use would be considered industrial. Based on the current understanding of the proposed future use of the Phase Two Property (fire station) would also be considered industrial. Phase Two Environmental Site Assessment 1951 Cyrville Road, Ottawa, ON 24/03/ City of Ottawa Final Report SNCLavalin Inc All rights reserved Confidential 4

10 Soil within the Phase Two Property would be classified as coarse textured since at least 1/3 of the soil at the site, measured by volume, consists of soil that contains more than 50 percent by mass of particles that are 75 µm or larger in mean diameter (Appendix A). Based on the above information, the following soil and groundwater standards have been selected for comparison purposes at the Phase Two Property: Full Depth Background Site Condition Standards for nonagricultural property use (i.e. MOECC, 2011; Table 1) will be applied in those portions of the Phase Two Property located within 30 m from the surveyed top of bank of the Green s Creek river valley. This is based on the current information available concerning the area of natural significance associated with Green s Creek. The top of bank location was provided by the City of Ottawa. Full Depth Generic Site Condition Standards in a NonPotable Groundwater Condition for coarse textured soil and industrial/commercial/community property use (i.e. MOECC, 2011; Table 3) would apply in those portions of the Phase Two Property located more than 30 m from any identified areas of natural significance (i.e. more than 30 m from the top of bank for the Green s Creek river valley). Generic Site Condition Standards for Use within 30 m of a Water Body in a NonPotable Groundwater Condition for coarse textured soil and industrial/commercial/community property use (i.e. MOECC, 2011; Table 9) would also apply in portions of the Phase Two Property located within 30 m of water bodies (Green s Creek). As these areas coincide with areas where MOECC Table 1 standards would apply and MOECC Table 9 site condition standards are less stringent than MOECC Table 1 standards, direct comparison to Table 9 standards is not discussed in this report. Should remediation or filing of a Record of Site Condition be planned, information used in the selection of site condition standards should be confirmed.

11 3 BACKGROUND INFORMATION 3.1 PHYSICAL SETTING The Phase Two Property is located at an elevation of approximately 64 m above mean sea level. The topography in the vicinity of the site generally slopes to the north/northeast, toward Green s Creek. Green s Creek is located immediately north of the Phase Two Property and flows to the east in this area. Black Creek, located east of the Phase Two Property, drains north into Green s Creek northeast of the site. Green's Creek eventually discharges to the Ottawa River approximately 7 km northeast of the site. Note that the current locations of Green s Creek and Black Creek in the area of the site are largely manmade; their original channels have been modified, and in some areas, completely altered (e.g. backfilled). Green s Creek and Black Creek have been identified as areas of natural significance (refer to Figure 2); however, there are limited or conflicting details on the geographic boundaries and rationale for these areas of natural significance when different regulatory bodies are consulted. As the precise locations of these areas of natural significance are not well defined, the area of natural significance adjacent to the Phase Two Property has been interpreted by SNCLavalin, in consultation with the City, to include both Green s Creek and its surrounding undeveloped valley lands. As reported in the Phase One ESA for the property at 1951 Cyrville Road (SNCLavalin, 2015), previous investigations at the site described surficial soils as sandy fill overlying clay and native sand deposits. Publicly available borehole and water well records are generally consistent and have identified gravel, silt and sand fill with evidence of construction waste overlying clay and sand deposits. Bedrock has not been encountered in previous onsite investigations. Regional records include records of shale bedrock within 250 m of the site encountered at depths of 9.8 to 12.5 m bgs. Groundwater has been previously encountered onsite at depths ranging from 2.7 to 3.1 m bgs and was interpreted to flow to the north toward Green s Creek. 3.2 PAST INVESTIGATIONS A summary of past investigations is presented in the Phase One ESA for the property at 1951 Cyrville Road (SNCLavalin, 2015). Based on past investigations and the findings of the 2015 Phase One ESA, areas of potential environmental concern (APECs) identified for the 1951 Cyrville Road property are shown on Figure 2.

12 4 SCOPE OF INVESTIGATION 4.1 OVERVIEW OF SITE INVESTIGATION AND MEDIA INVESTIGATED The objective of this work program was to evaluate soil and groundwater conditions relative to the area that is proposed for the future development as a fire station. The investigation included characterization of potential impacts to soil and groundwater within the Phase Two Property related to APECs from onsite sources identified by the 2015 Phase One ESA and their associated Potential Contaminants of Concern (PCOCs). The following table summarizes APECs and PCOCs within the Phase Two Property that were identified in the Phase One ESA for the property at 1951 Cyrville Road (SNCLavalin, 2015). APEC Identifier (refer to Figure 2) APEC 1 APEC 14 APEC 15 Description of APECs Associated PCOCs Media Potentially Impacted The site was historically extensively backfilled with fill of unknown source and/or quality including quarry operations circa 1960s/1970s, reported backfilling circa 1980s and observed fill at the site. The site is seasonally used for street sweepings dewatering and observed staining. The site has reportedly been used periodically for outdoor storage/stockpiling of emulsified asphalt.

13 Submit selected soil samples for laboratory analyses of PCOCs including petroleum hydrocarbons (F1F4 PHC), VOCs (including BTEX), PAHs, metals, SAR, and EC; Coordinate offsite disposal of excess soil generated during drilling including review of laboratory waste characterization analyses; Install six (6) environmental overburden monitoring wells in the completed boreholes to permit groundwater monitoring and sampling. One (1) monitoring well was to be completed as a multilevel well with two (2) well intervals (i.e. deep and shallow) 1 ; Collect selected groundwater samples from the six (6) newly installed monitoring wells for laboratory analyses of PCOCs including F1F4 PHC, VOCs (including BTEX), PAHs, dissolved metals and general water quality parameters; Conduct hydraulic conductivity testing in three (3) monitoring wells; and, Compare soil and groundwater analytical results to applicable provincial standards. The Phase Two ESA program was undertaken in conjunction with geotechnical investigations, as outlined in SNCLavalin s proposal, dated November 13, Methodologies and findings associated with the geotechnical investigation are provided under separate cover. 4.2 PHASE ONE CONCEPTUAL SITE MODEL The Phase One Conceptual Site Model (CSM) was included in the Phase One ESA for the property at 1951 Cyrville Road (SNCLavalin, 2015). 4.3 DEVIATIONS FROM SAMPLING AND ANALYSIS PLAN One (1) additional test pit was completed (total of 7 test pits) at the request of the City to provide more coverage in the southwest portion of the site. Also, only one (1) well interval was installed at the proposed multilevel monitoring well because bedrock was encountered at shallower depth than had been anticipated (i.e. the deep overburden well interval was not required). 4.4 IMPEDIMENTS Flowing sands were encountered at depths of approximately 4 m in all boreholes and test pits and caused impediments to both. In the boreholes, this condition required the drilling method to switch from using augers to waterfilled temporary Hsized casing. As a result of using the casings, which have a smaller inner diameter than the augers, some wells were installed using smaller diameter PVC pipes (e.g. 32 mm diameter) than the larger 51 mm PVC pipes than had been proposed. This drilling and well installation modification had no material effect on the results of the Phase Two ESA. 1 Two (2) hydraulic piezometers were also installed for geotechnical purposes and are not discussed in this report.

14 The flowing sands encountered in the test pits made it difficult to observe deep soil conditions and bedrock; however, deep soil and bedrock were encountered and observed from the boreholes. Therefore, this impediment had no material effect on the results of the Phase Two ESA. Another impediment at the site included a large subdrain tile field across the entire work area. The City of Ottawa marked the locations of the tile drains to enable investigations to be conducted without damaging the drains (these drains reportedly discharge to Green's Creek). This impediment had no material effect on the results of the Phase Two ESA. No other significant impediments were encountered during field investigations.

15 5 INVESTIGATION METHOD 5.1 GENERAL The field program for the Phase Two ESA was completed in December 2015 and January 2016 and consisted of the following elements: Preliminary Activities; Borehole Drilling and Soil Sampling; Test Pit Excavation and Soil Sampling; Groundwater Monitoring Well Installation; Groundwater Monitoring and Sampling; Hydraulic Conductivity Testing; and, Waste Disposal. The Phase Two ESA program was completed by SNCLavalin field staff using field and laboratory analysis protocols based on O. Reg. 153/04, as amended, and standard operating procedures (SOPs) described in the SNCLavalin Field Work Guidance Manual. All field tasks completed as part of the investigation were subject to a site specific health and safety program implemented by SNCLavalin. 5.2 DRILLING AND EXCAVATION Prior to conducting any intrusive work, SNCLavalin retained USL1 Underground Service Locators Inc. (USL1) of Ottawa, Ontario to locate onsite public and private underground services. USL1 confirmed that each proposed drilling and excavation location was free of public and/or private services prior to any ground disturbance. City representatives also assisted in locating onsite private utilities, including a reported subdrain tile field at the site, while USL1 personnel were on site Drilling From December 15 to 21, 2015, nine (9) boreholes (BH1 to BH9) were drilled under the supervision of SNCLavalin personnel. Drilling was conducted using a CME55 truckmounted hydraulic drill rig operated by George Downing Estate Drilling Ltd. (Downing) of Grenvillesurla Rouge, Québec. Boreholes were completed to depths ranging from 4.9 m bgs (terminating in overburden) to 13.0 m bgs (terminating in bedrock). Boreholes were advanced in overburden using hollow stem augers (210 mm outer diameter) and/or Hcasings (114 mm outer diamater), and NQ Phase Two Environmental Site Assessment 1951 Cyrville Road, Ottawa, ON 24/03/ City of Ottawa Final Report SNCLavalin Inc All rights reserved Confidential 10

16 [71 mm outside diameter (O.D.)] coring equipment in bedrock 2. In overburden, continuous soil samples were collected, where possible, using 0.6 m long, 51 mm O.D. split spoon samplers. The split spoons were cleaned between samples to minimize the potential for crosscontamination. Borehole locations are shown in Figure 3. Borehole logs including sample descriptions are provided in Appendix B Test Pitting On December 18, 2015, seven (7) test pits (TP1 to TP7) were excavated under the supervision of SNCLavalin personnel. Excavation was conducted using a Caterpillar, model 336, hydraulic shovel operated by Geo. W. Drummond Ltd. (Drummond) of Ottawa, Ontario. Test pits were completed to depths ranging from 4.0 m bgs to 4.9 m bgs. All terminated in overburden with the exception of TP2 that terminated at 4.9 m bgs on bedrock. Five (5) test pits (TP3, TP4, TP5, TP6 and TP7) were terminated at 4.0 m bgs due to caving of the test pit walls. Soil samples were collected as grab samples off the excavator bucket using a hand trowel. Samples were collected from each test pit at approximately 0.5 m intervals. The hand trowel was cleaned between samples to minimize the potential for crosscontamination. Test pit locations are shown in Figure 3. Test pit logs including sample descriptions are provided in Appendix C Soil Sampling All collected soil samples were identified using nomenclature to identify the borehole (BH) or test pit (TP) and sequential soil sample (e.g. TP24 is the fourth soil sample from the test pit identified as TP2). Soil samples were immediately split into two (2) portions for field logging/screening and for possible laboratory analysis. The field logging/screening portion was placed in a sealable plastic bag and logged in the field for soil type (colour, moisture content, cohesiveness, etc.) and visual evidence of impacts (i.e., staining, presence of ash or debris, etc.). Field screening methods are described in Section The portion of each soil sample collected for potential laboratory analysis was placed directly into laboratory supplied sample jars and placed in a cooler with ice. At least one (1) soil sample from each borehole and each test pit was submitted for laboratory analyses. Twentyfive (25) soil samples collected from boreholes and eleven (11) soil samples collected from test pits were submitted for laboratory analyses of PCOCs, including F1F4 PHC, VOCs (including BTEX), PAHs, metals, SAR, and/or EC. Additional soil samples collected for quality assurance and quality control (QA/QC) purposes are discussed in Section One (1) 2 Bedrock coring was conducted to confirm the depth of bedrock for geotechnical purposes. Bedrock conditions are not discussed in any detail in this report.

17 soil sample was analysed for O.Reg.347 waste characterization parameters including Schedule 4 toxicity characteristic leaching procedure (TCLP) metals, inorganics, volatiles, semivolatiles and PCBs as well as flashpoint Field Screening Measurements The portion of each soil sample for field logging/screening was placed in a sealable plastic bag. Maximum headspace vapour readings in the sample bags were measured in the field using an RKI Eagle 2 organic vapour meter (OVM). The OVM was calibrated daily in the field in methaneelimination mode to one (1) hexane gas standard. Field screening with the OVM was used to qualitatively direct selection of samples for volatile parameters (e.g., VOCs/F1 PHC) Groundwater Monitoring Well Installation Six (6) of the boreholes (BH1, BH2, BH6, BH7, BH8 and BH9) drilled in December 2015 were instrumented with monitoring wells and were redesignated as MW1, MW2, MW6, MW7, MW8 and MW9, respectively. Monitoring wells were constructed by Downing using PVC well screens and risers and the annulus surrounding each well was backfilled with silica sand and bentonite as detailed in the borehole logs included in Appendix B. Each well was protected at surface with a flushtoground metal protective casing. Each monitoring well was instrumented with an inertial hand pump constructed of a plastic foot valve and low density polyethylene tubing. Monitoring wells were developed on December 21, 2015 by removal of a minimum of 50 L of groundwater or by purging the well dry three (3) times. Field measurements of ph, temperature and EC were recorded during monitoring well development to confirm these parameters had stabilized prior to ceasing development. Field parameters were measured using a Hanna Instruments HI ph/conductivity/temperature meter calibrated in the field using calibration solutions provided by the manufacturer. Observations of groundwater turbidity and any evidence of the presence of light non aqueous phase liquid (LNAPL) were also recorded. All six (6) monitoring wells were registered with the MOECC as "a cluster" in accordance with Ontario Regulation 903. A copy of the well record is included in Appendix B Groundwater Field Measurements On December 21 and 23, 2015 and January 8, 2016, groundwater monitoring was conducted at each of the six (6) monitoring wells (MW1, MW2, MW6, MW7, MW8 and MW9). Monitoring well locations are presented in Figure 3. Monitoring activities included measuring water levels and assessing the presence of LNAPL in each monitoring well. Water levels were measured from the top of the PVC monitoring well riser pipe using an electronic water level meter and/or an interface probe. During each event, the potential presence of LNAPL was assessed using either the interface probe and/or through visual inspection of groundwater Phase Two Environmental Site Assessment 1951 Cyrville Road, Ottawa, ON 24/03/ City of Ottawa Final Report SNCLavalin Inc All rights reserved Confidential 12

18 purged from the well. Prior to use in each well, the water level meter and interface probe were cleaned to minimize the potential for crosscontamination Groundwater Sampling Groundwater samples were collected from each of the six (6) monitoring wells (MW1, MW2, MW6, MW7, MW8 and MW9) on December 23, 2015 and January 8, Groundwater samples were collected using dedicated inertial hand pump on December 23, 2015 and using a peristaltic pump on January 8, Prior to sampling with the inertial hand pump, a minimum of three (3) well volumes of groundwater were purged from each monitoring well or the monitoring wells were purged dry at least once. Prior to sampling with the peristaltic pump, a minimum of three (3) well volumes of groundwater were purged from each monitoring well. Field measurements of ph, temperature and EC were recorded during purging to confirm these parameters had stabilized prior to sampling. Field parameters were measured using the Hanna Instruments meter described in Section Observations of groundwater turbidity and any evidence of the presence of light non aqueous phase liquid (LNAPL) were also recorded. Groundwater samples collected for metals analyses were field filtered using dedicated inline 0.45 μm filters. Samples for laboratory analysis were collected directly into laboratory supplied sample bottles and placed in a cooler with ice. One (1) groundwater sample from each monitoring well was submitted for laboratory analyses of PCOCs including F1 PHC, VOCs (including BTEX) and metals (collected on December 23, 2015) and F2F4 PHC and PAHs (collected on January 8, 2016). Two (2) groundwater samples collected on December 23, 2015 were also analysed for general water quality parameters. Additional samples collected for QA/QC purposes are discussed in Section Groundwater Hydraulic Conductivity Testing Hydraulic conductivity field testing was completed at three (3) monitoring wells (MW6, MW7 and MW8) on December 23, 2015 using both falling and rising head test methods. Recovery in monitoring well MW7 was instantaneous and could not be analysed. Field data from hydraulic conductivity tests completed on the other two (2) wells were analysed using the method of Bouwer and Rice (1976) to estimate the hydraulic conductivity of the aquifer material at each location Analytical Testing All soil and groundwater samples were collected in laboratory prepared sampling containers and stored in a cooler with ice until delivery to the analytical laboratory. Laboratory analyses of soil and groundwater were completed by Paracel Laboratories Ltd. (Paracel) of Ottawa, Ontario. Paracel is accredited by the Canadian Association for Laboratory Accreditation Inc. (CALA).

19 Residue Management Procedures Excess soil generated during drilling was temporarily placed in a metal rolloff bin and stored onsite pending waste characterization results. The rolloff bin was removed for offsite disposal at a licensed waste facility by Tomlinson Environmental Services (Tomlinson) of Ottawa, Ontario on January 5, Elevation Surveying Borehole and test pit locations and ground surface elevations were surveyed by City staff prior to intrusive activities at the site. Monitoring well riser pipe elevations were measured in the field by SNCLavalin staff. Ground surface and top of pipe elevations are reported relative to a local benchmark [Magnail # 10 located at the north corner of the intersection of Cyrville Road with the Entrance to 1960 Cyrville Road as shown in Figure 2 with NAD 83 coordinates of N , E and having a geodetic elevation of m above mean sea level (amsl)] Quality Assurance and Quality Control Measures A QA/QC program was implemented to minimize and quantify impacts introduced during sample collection, handling, shipping and analysis. Details of the QA/QC program are discussed in Appendix D.

20 6 REVIEW AND EVALUATION 6.1 GEOLOGY Stratigraphic information collected during the current intrusive investigation indicates that the overburden at the site generally consists of an initial layer of granular fill, followed by a heterogeneous fill consisting of sand, silt and clay in varying proportions underlain by native sand and gravelly sand till with varying silt content. Granular fill generally extended from surface to between 0.6 and 1.2 m bgs and was encountered to a maximum depth of 4.0 m. The heterogeneous fill extended to a maximum depth of 4.9 m bgs and was encountered in all boreholes and test pits. Debris and waste materials, including asphalt, plastic, wood, brick, concrete, glass, metal, pipe and wires, was observed in this fill unit at all locations. Across the area investigated, debris and waste was observed in fill from near surface to a maximum depth of 5.0 m bgs. A layer of ash mixed with other debris was encountered in TP1 (2.5 to 3.0 m bgs) and TP3 (at 2.0 m bgs). Varying amounts of ash were also encountered in the fill in TP2 (1.5 to 2.5 m bgs), TP3 (at 3.0 m bgs) and TP6 (2.5 to 3.0 m bgs). Native sand was found in the interval from 3.4 to 6.7 m bgs. The native sand was typically "flowing" at a depth of 4 m bgs, when disturbed. Till was encountered in four (4) of the boreholes (BH2, BH4, BH5 and BH9) at depths ranging from 5.8 to 7.0 m bgs and extending to bedrock. Shale bedrock was encountered at depths ranging from 5.6 m bgs (BH9) to 7.0 m bgs (BH4). Additional details on the soil stratigraphy are provided in the borehole logs in Appendix B. 6.2 GROUNDWATER ELEVATIONS AND FLOW DIRECTION Groundwater monitoring results are summarized in Table 1. Water levels measured on December 23, 2015 ranged from 2.2 to 3.2 m bgs, resulting in groundwater elevations ranging from to m amsl. Similar water levels were measured on January 8, 2016 ranging from 2.5 to 3.2 m bgs, resulting in groundwater elevations ranging from to m amsl. Based on water levels measured in December 2015 and January 2016, the interpreted horizontal groundwater flow direction in the overburden across the Phase Two Property is to the north/northeast toward Green s Creek as shown in Figures 4 and 5. A sheen was noted on purged water removed from MW6 during development on December 21, 2015 and on purged water removed from MW7 prior to sampling on December 23, No other evidence of free product, visible petroleum film or sheen was observed during monitoring, purging or sampling of the monitoring wells in December 2015 and January Phase Two Environmental Site Assessment 1951 Cyrville Road, Ottawa, ON 24/03/ City of Ottawa Final Report SNCLavalin Inc All rights reserved Confidential 15

21 6.3 GROUNDWATER HYDRAULIC GRADIENTS Based on the interpreted groundwater contours presented in Figures 4 and 5, a horizontal hydraulic gradient of approximately was calculated in overburden at the site. It is anticipated that the hydraulic gradient might be steeper in the immediate vicinity of Green's Creek. 6.4 GROUNDWATER HYDRAULIC CONDUCTIVITY TESTING Results from the hydraulic conductivity field tests for MW6 and MW8 are provided in Appendix E. Hydraulic conductivity values from the falling and rising head tests were calculated using the method of Bouwer and Rice (1976). The hydraulic conductivities ranged from 4.2 x 10 5 m/s and 1.9 x 10 5 at MW6 to 3.6 x 10 4 at MW8. The results from the falling and rising head tests performed at monitoring well MW7 were inconclusive as the groundwater recovery was instantaneous which suggests a higher hydraulic conductivity than the other tested wells. Based on the abovenoted hydraulic conductivities and gradient, the estimated average groundwater flow velocity at the site is 42 m/yr. 6.5 SOIL FIELD SCREENING Field observations and the results of field screening of soil samples are summarized in the borehole logs (Appendix B) and the test pit logs (Appendix C). OVM readings measured during borehole drilling ranged from below the instrument detection limit to 100 parts per million by volume (ppmv). All OVM readings measured during test pitting were below the instrument detection limit. 6.6 SOIL QUALITY Analysed concentrations in soil are presented alongside the selected provincial standards in Tables 2 to 5. As discussed in Section 2.1, soil samples collected within 30 m of the surveyed top of bank of the Green s Creek river valley (i.e. 30 m from the interpreted limit of the areas of natural significance) were compared to MOECC Table 1 standards. All other samples were compared to MOECC Table 3 standards. Copies of laboratory certificates of analyses are included in Appendix F. The following table summarizes sampling locations where analysed concentrations in soil exceeded MOECC standards applicable to the area (i.e. Table 1 within 30 m of the top of the Green's Creek bank and Table 3 in other areas).

27 The groundwater is mildly brackish and is dominated by NaCl ions. This reflects impacts from road salt, potentially from historical use of the area (and/or the adjacent site to the west) as a snow dump, and/or current use of the area as a dewatering facility for street sweepings. The groundwater is considered to be hard, and the hardness has resulted from cation exchange processes (i.e. Na from groundwater has adsorbed to soil particle surfaces, thus displacing Ca and Mg into solution and increasing hardness). Iron concentrations in the groundwater are relatively elevated which suggests groundwater conditions are anaerobic. These conditions have likely resulted from microbial decomposition of the observed buried organic materials (e.g. wood), thereby depleting dissolved oxygen concentrations. There is no evidence of fertilizer impacts in the groundwater given that nitrate and nitrite were not detected Quality Assurance and Quality Control Results The results of the quality assurance and quality control (QA/QC) program are discussed in Appendix D. The results of field and laboratory QA/QC measures associated with analysed soil and groundwater samples were generally acceptable. Deviations are discussed in Appendix D.

28 7 CONCLUSIONS AND RECOMMENDATIONS 7.1 CONCLUSIONS Based on the results of the current investigation, concentrations of PCOCs, including F1F4 PHC, VOCs, PAHs, metals and/or salinity parameters, exceed MOECC standards in soil and/or groundwater samples collected from the site and these impacts have not been delineated laterally. The following provides a summary of MOECC standards exceedances: Concentrations of F2F4 PHC exceeding MOECC standards were measured in soil samples collected across the centre of the site (BH2, BH6, TP4 and TP5 at depths ranging from 1.0 to 3.0 m bgs). Groundwater analytical results do not indicate petroleum hydrocarbon impacts to groundwater in the area. Acetone concentrations in soil samples collected at three (3) locations in the central portion of the site (BH3, BH7 and BH9) and the chloroform concentration at one (1) monitoring well (MW2) exceeded MOECC standards. With the exception of these exceedances, VOC concentrations were generally less than laboratory MDLs. PAH concentrations exceeding MOECC standards were measured in soil samples collected across the site and at depths ranging from 0.6 to 3.0 m bgs. PAH concentrations in groundwater exceeded MOECC standards in one (1) monitoring well (MW7). Metals concentrations exceeding MOECC standards were measured primarily in soil samples collected in the west portion of the site (BH3, BH4, TP1, TP6 and TP7 at depths ranging from 1.0 to 3.6 m bgs) and also at one (1) test pit location in the east portion of the site (TP5 at a depth of 1.0 m bgs). Metals concentrations exceeded MOECC standards at one (1) monitoring well (MW9 located within the area compared to MOECC Table 1 standards). EC and/or SAR concentrations exceeded MOECC standards in soil samples collected from the northeast portion of the site (BH2, TP1, TP3, TP4 and TP5) at depths ranging from 0.6 to 4.0 m bgs. Overall, soil and groundwater quality at the site are considered to be poor. Buried wastes are present throughout the soil (fill) to maximum depths ranging from approximately 4 to 5 m bgs. Numerous soil contaminants were detected sporadically in the soil. There do not appear be specific point sources of soil contamination; rather, impacts appear to be associated with unpredictable variations in the quality of the fill. The groundwater shows evidence of road salt impacts, and isolated impacts by PAHs (likely from associated soil impacts) and chloroform (likely related to municipal water discharges in the street sweeper dewatering area or, less likely, the historical chloramine spill near the northwest corner of the site). Soil and groundwater impacts were not fully delineated during the current Phase Two ESA. Historic infilling extended beyond the limits of the current investigation area and were primarily related to quarrying operations prior to City ownership Phase Two Environmental Site Assessment 1951 Cyrville Road, Ottawa, ON 24/03/ City of Ottawa Final Report SNCLavalin Inc All rights reserved Confidential 23

29 of the site. As such, delineation of these impacts was beyond the scope of the current investigation. 7.2 RECOMMENDATIONS Based on the results and conclusions of the current investigation, the following recommendations are offered with respect to proposed future development of the site as a fire station: Contaminated soil and groundwater in the proposed development area should either be remediated to applicable MOECC site conditions standards or be assessed relative to potential human health and ecological risks. o Soil remediation would require excavation and offsite disposal of soil at a licensed landfill facility. Groundwater remediation could likely be largely accomplished during soil remediation by concurrent removal of water entrained in the soil and excavation dewatering. Assuming all soil in the proposed development area (approximately 6,000 m 2 ) would require remediation to a depth of approximately 4 m (i.e. 24,000 m 3 of soil), the estimated cost for remediation is approximately $6,000,000. o Human health and ecological risk assessments could be conducted to evaluate the risks of developing the site as a fire station while leaving soil and groundwater impacts in place. Given that full delineation of contaminants has not been achieved, a RSCcompliant risk assessment cannot presently be completed. Rather, only a limited due diligence risk assessment is possible. The risk assessment would identify site specific target levels or "acceptable" concentrations of contaminants based on sitespecific conditions for the proposed property use as a fire station. The risk assessment may also propose risk management actions, if deemed necessary (e.g. limited soil remediation, contaminated soil capping, methane monitoring, etc.). The estimated cost for a due diligence risk assessment and risk management plan is approximately $25,000. A soil management plan should be developed for all excavation/soil generation activities at the site. The plan should recognize the limited potential for reuse of excavated soil due to the presence of wastes and exceedances of MOECC Table 1 standards. It is anticipated that virtually all excess soil generated during construction activities would need to be disposed offsite at a licensed landfill. The plan should also consider the guidance provided in the MOECC's (2014) document "Management of Excess Soil A Guide for Best Management Practices". A groundwater management plan should also be developed if excavations below the water table are anticipated. The plan should evaluate whether a MOECC Permit to Take Water (PTTW) would be required (note that changes to the PTTW may be enacted by the MOECC in 2016, and these should be considered in the plan). The plan should also consider whether water treatment will be required (e.g. sediment removal, etc.) and whether environmental compliance approvals (ECAs) or sewer use agreements would be required Phase Two Environmental Site Assessment 1951 Cyrville Road, Ottawa, ON 24/03/ City of Ottawa Final Report SNCLavalin Inc All rights reserved Confidential 24

99 APPENDIX D Quality Assurance & Quality Control

100 Quality Assurance and Quality Control Program A quality assurance and quality control (QA/QC) program was implemented to minimize and quantify data variability introduced during sample collection, handling, shipping and analysis. As part of the QA/QC program, sampling protocols included minimizing sample handling, submitting field QA/QC samples, using dedicated non contaminating sampling equipment, wearing new disposable vinyl gloves for each sample handled, using sample specific identification and labeling procedures and using chain of custody records. Field Quality Assurance and Quality Control The field QA/QC program included the analysis of field duplicate and field blank samples. Duplicate samples were analysed for each analytical parameter at a frequency of approximately 10% or a minimum of one (1) duplicate for each analytical parameter. The field duplicates were blind duplicates in that duplicate pairs were not identified to the laboratory. Field duplicate soil and groundwater samples are identified in Tables 2 to 5 (Soil) and Tables 7 to 11 (Groundwater). In addition, one (1) methanol blank sample was analysed for volatile parameters as part of the soil sampling program and one (1) field blank sample was analysed for the full analytical suite during the groundwater sampling program. Laboratory Quality Assurance and Quality Control Chemical analyses were performed by a laboratory accredited by the Standards Council of Canada (SCC). Laboratory analyses for Ontario Regulation 153/04 parameters were completed in accordance with Standard Methods (MOE, CCME, US EPA or ASTM) and generally accepted industry practices. Laboratory QA/QC measures included analysis of laboratory blank, spiked blank, duplicate and matrix spike samples. Laboratory acceptance criteria reported on laboratory certificates of analyses were used to assess the quality of laboratory QA/QC measures. Results of the QA/QC Program Field Duplicate Results Field duplicates were evaluated by estimating the potential uncertainty, expressed as a relative percent difference (RPD), in the analytical determinations calculated from the blind field duplicate and sample pairs. RPD was determined as follows: RPD=ABS((S x D x )/avg(s x D x ))*100 Where: the RPD is a measure of the potential uncertainty (combined field and laboratory variance) in percent between the duplicate and sample; ABS((S x D x ) represents the absolute value of the difference in reported concentrations of sample x (S x ) and the duplicate sample (D x ) of sample x; and avg(s x D x ) is the average concentration of the parameter of interest in the sample and duplicate sample.

101 Since data quality objectives for field duplicate analyses are not provided by the MOECC, field precision data quality was assessed relative to regulatory guidance provided by the province of British Columbia (BC MWLAP, 2003). Following British Columbia guidance, RPD values were calculated only where detected concentrations in both duplicate pair samples were greater than five (5) times the laboratory detection limit. Calculated RPD values were then compared to an acceptability limit of 50%. Analytical results for duplicate soil and groundwater samples are presented alongside the analytical results for their respective duplicate pair in Tables D.1 to D.4 (soil) and Tables D.5 to D.8 (groundwater). All calculated RPD values for field duplicate pairs were less than 50% and therefore considered acceptable. Field Blank Results Field blank samples can identify potential contamination of samples introduced during collection or analysis due to crosscontamination or mishandling of samples. As shown in Tables D.9 to D.13, concentrations of all parameters analysed in field blank samples were less than five (5) times laboratory RDLs and therefore considered acceptable. Laboratory QA/QC Results of laboratory QA/QC measures associated with soil and groundwater analyses are presented in the laboratory certificates of analysis in Appendix F (soil) and Appendix G (groundwater). Laboratory certificates of analysis were reviewed for any potential QA/QC issues identified by the laboratory. All QA/QC issues identified by the laboratory were determined to be negligible based on the review of alternate QA/QC results. No QA/QC issues with the potential to affect the conclusions presented in this report were identified by the laboratory. Acetone Concentrations in Soil Elevated acetone concentrations were noted in three (3) soil samples collected during borehole drilling (BH03/SS6, BH06/SS5 and BH07/SS4). An elevated hexane concentration was also reported for one (1) of these soil samples (BH07/SS4). As all other VOC concentrations were reported to be less than laboratory MDLs, and acetone and hexane are often used as laboratory reagents, the analytical laboratory was contacted to verify elevated concentrations in these samples. The laboratory found no evidence in their QA/QC reports to suggest the elevated concentrations were the result of contamination of the samples during analyses. Overall Data Quality Based on the above discussions, the results of field and laboratory QA/QC measures associated with analysed soil and groundwater samples were generally acceptable. Where deviations were identified, the effects were determined to be negligible and are not believed to have materially affected the conclusions based on these results with the exception of elevated acetone and/or hexane concentrations in soil samples BH03/SS6, BH06/SS5 and BH07/SS4. It is suspected

102 that the acetone and hexane detections are artifacts of some form of crosscontamination and are not representative of actual concentrations at the site. This could be confirmed with additional sampling. References British Columbia Ministry of Water, Land, and Air Protection (BC MWLAP), British Columbia Field Sampling Manual. January 2003.

RPD: Relative percent difference. Soil results are reported on a dry weight basis when the units are denoted with 'dry'. Where %Solids is reported, moisture loss includes the loss of volatile hydrocarbons. CCME PHC additional information: The method for the analysis of PHCs complies with the Reference Method for the CWS PHC and is validated for use in the laboratory. All prescribed quality criteria identified in the method has been met. F1 range corrected for BTEX. F2 to F3 ranges corrected for appropriate PAHs where available. The gravimetric heavy hydrocarbons (F4G) are not to be added to C6 to C50 hydrocarbons. In the case where F4 and F4G are both reported, the greater of the two results is to be used for comparison to CWS PHC criteria. Page 41 of 41
