Approximately 6,082 cubic metres of material was mechanically screened on-site in order to remove deleterious materials (i.e. scrap metal, tires, windshields, plastic, rubber hoses, etc.) from the fill material. Screening activities were completed following the excavation and off-site disposal of highly impacted material (see below). A Powerscreen Horizon 6203 mobile screening plant with Certificates of Approval for air and waste management system was used to screen the material. The screener was moved from the south to north end of the property as screening progressed. Soil from the Identify areas that the were estimated designated quantities for screening of soil or sediment, was moved if any, to the removed general from vicinity and of not the returned screener to using the RSC a property as measured in, or equivalent to, the in-ground volume in cubic metres. Approximately 2,987 cubic metres of soil that was classified as non-hazardous waste was excavated and disposed off-site at MOE-licensed facilities prior to the commencement of screening activities. Approximately 299 cubic metres of screened soil that did not meet the Table 4 SCS for subsurface soil was disposed off-site at MOE-licensed facilities. Approximately 976 tonnes of deleterious material was disposed off-site at MOE-licensed facilities. Identify the estimated quantity of the soil, if any, being brought from another property to and deposited at the RSC property, not including any soil that may have originated at but been remediated off the RSC property not including any soil that may have been remediated off the property and brought back to the property as measured in, or equivalent to, the in-ground volume in cubic metres. Approximately 8,000 cubic metres of soil were imported from a borrow area located in Stoney Creek, Ontario for use as grading material in the railway safety berm area. The soil that was imported from the borrow area was characterized in accordance with Schedule E of O.Reg. 153/04, as amended. The imported soil was determined to meet the requirements of Section 55 of O.Reg. 153/04, as amended. Indicate if any soil, sediment or ground water at the RSC property that is or was located within 3 metres of the RSC property boundary has been remediated or removed for the purpose of remediation. Yes. The remedial excavation extended to the west property line and approximately 50 m along the westernmost portion of the north property line.

None required. Supporting Documents Indicate whether there are any monitoring requirements or any requirements for care, maintenance or replacement of any monitoring or control works for known existing contaminants, if any, on the RSC property, after the certification date, and whether any monitoring requirements or requirements for care, maintenance or replacement of any monitoring or control works are ground water management measures or soil management measures. No monitoring or maintenance activities are required. CPU No XZRRD dated December 12, 2012 prohibits the installation of potable water supply wells at any of the parcels located within the RSC property in order to eliminate potential exposure to marginal exceedances of the Table 4 Site Condition Standards for cobalt, sodium, and uranium. The CPU also sets forth notification requirements for changes in ownership or occupancy. All parcels within the RSC property will be connected to the Town of Grimsby's municipal potable water supply, and so homeowners would not need to install potable water supply wells in any case.

34 Owner Information RSC Property Information Environmental Condition Contaminant Concentrations ESA Information QP Profile Information Certification Statement QP Certification Statement Owner Certification Statement Supporting Documents QP Certification Statement E As the qualified person, I certify that: * A phase one environmental site assessment of the RSC property, which includes the evaluation of the information gathered from a records review, site reconnaissance, interviews, a report and any updates required, has been conducted in accordance with the regulation by or under the supervision of a qualified person as required by the regulation. A phase two environmental site assessment of the RSC property, which includes the evaluation of the information gathered from planning and conducting a site investigation, a report, and any updates required, has been conducted in accordance with the regulation by or under the supervision of a qualified person as required by the regulation. The information represents the site conditions at the sampling points at the time of sampling only and the conditions between and beyond the sampling points may vary. As of 2012/08/01, in my opinion, based on the phase one environmental site assessment and the phase two environmental site assessment, and any confirmatory sampling, there is no evidence of any contaminants in the soil, ground water or sediment on, in or under the RSC property that would interfere with the type of property use to which the RSC property will be put, as specified in the RSC.

53 Phase Two Conceptual Site Model Escarpment Vista Estates Inc. 590 Main Street West, Grimsby May 21, 2013 Introduction The Phase Two Conceptual Site Model (CSM) was derived from direct observation at the Site and the information cited in the following documents: Site Remediation Report, Escarpment View Estates, Grimsby, Ontario, prepared by AMEC Americas Limited (AMEC) and dated January 31, Phase One Environmental Site Assessment (ESA), Escarpment View Estates, Grimsby, Ontario, prepared by AMEC and dated March 20, Phase Two Environmental Site Assessment, Escarpment View Estates, 590 Main Street West, Grimsby, Ontario, prepared by AMEC and dated April 17, Revised Risk Assessment for Escarpment Vista Estates, 590 Main Street West, Grimsby, Ontario, Ontario Ministry of Environment (MOE) Risk Assessment (RA) No UAKMJ, prepared by NovaTox Inc. (Novatox) and dated July 6, Main Street West, Grimsby, Certificate of Property Use (CPU) No XZRRD, prepared by MOE and dated December 18, Phase One Environmental Site Assessment Update, Escarpment View Estates, 590 Main Street West, Grimsby, Ontario, prepared by MBN and dated January 24, Phase Two Environmental Site Assessment Update, Escarpment Vista Estates, 590 Main Street West, Grimsby, Ontario, prepared by MBN and dated May 21, The Phase Two CSM is described below. Site Setting, Structures, and APECs/PCAs The Site setting and layout are shown on Figures 1 and 2, respectively. The Site is located at 590 Main Street West in Grimsby, Ontario. The current permitted property uses are industrial for parcel PIN (LT) and agricultural for parcel PINs (LT) and (LT). The westernmost portion for parcel PIN (LT) was also used as part of the auto wrecker s operation. The Record of Site Condition (RSC) property is currently vacant pending redevelopment with 176 residential lots with single family fully detached homes. The proposed subdivision layout is shown on Figure 3. The layouts of the homes that will be constructed at each property have not been shown as these will be determined at time of sale depending on the model that the purchasers select. No structures are currently present at the RSC property other than modular trailers that are used as a sales office. The sales office trailer does not have a basement and the floor is elevated above the ground surface. A self-contained (i.e. no sewer or water service connections) washroom is present at the rear of the sales office trailer. Electrical power to the developer s sales office trailer is provided by overhead lines. The developer commenced installation of Site services (i.e. sanitary and storm sewers and watermains) in March MBN Page 1

54 Phase Two Conceptual Site Model Escarpment Vista Estates Inc. 590 Main Street West, Grimsby May 21, 2013 Surrounding properties consist of the following property uses: North - railway, commercial, and residential; East residential; South commercial, residential and agricultural; and West residential and agricultural. The areas of potential environmental concern (APECs) and associated potentially contaminating activities (PCAs) are shown on Figure 1 and summarized in the table that is appended to the RSC. APEC-1 and APEC-6 are related to historic activities at the RSC property. The remaining APECs relate to current and/or historic activities at properties within the Phase One and Two ESA Study Area. The APECs are described in greater detail below: APEC-1 Former Auto Wrecking Yard (PCA 49): A former auto wrecking yard was present on the west side of the property associated with all of parcel PIN (LT), with encroachment on the western most portion of parcel PIN (LT). The auto wrecking yard operated from approximately 1955 to The yard was vacant after Areas with surficial oil staining and scatter car parts were visible. Contaminants of concern (COCs) include volatile organic compounds (VOCs), petroleum hydrocarbons (PHC), and metals in soil and ground water. Polyaromatic hydrocarbons (PAHs) were considered as potential COCs in ground water, but were rejected following an evaluation of PAH concentrations in soil samples that were collected during the remedial activities. APEC-2 Railway Tracks (PCA 46): Railway tracks are present adjacent to the north end of the RSC property. No records were recovered that would indicate that any releases have occurred on the railway tracks to the north of the Site. COCs include PHC, PAH, and metals in soil, and PHC and metals in ground water. The railway tracks are located hydraulically downgradient of the RSC property. APEC-3 Petroleum Storage (PCA 28): Petroleum storage tanks were identified at a transportation centre located hydraulically cross- and up-gradient of the RSC property in a southeasterly direction. COCs include benzene, toluene, ethylbenzene, xylenes (BTEX), PHC, and metals (i.e. lead) in soil and ground water. APEC-4 Petroleum Storage (PCA 28): Petroleum storage tanks were identified at a farm located cross- and up-gradient of the RSC property in a southwesterly direction. COCs include BTEX, PHC, and metals (i.e. lead) in soil and ground water. APEC-5 Autobody Shop (PCA 10) and Petroleum Storage (PCA 28): A car dealership is present at a property located up-gradient of the southeast corner of the RSC property in a southerly direction. A petroleum storage tank and autobody shop were identified at this location. COCs include VOCs, PHCs, and metals in soil and ground water. MBN Page 2

55 Phase Two Conceptual Site Model Escarpment Vista Estates Inc. 590 Main Street West, Grimsby May 21, 2013 APEC-6 Potential Large-Scale Pesticide Use (PCA 40): Historical records review indicate that large portions of parcel (LT) and (LT) were formerly used as agricultural lands, including orchards, until the early 1970s. It is possible that pesticides were used during this time period. COCs include organochlorine pesticides (OCPs) and metals (i.e. arsenic and lead) in soil. Physical Setting, Geology, and Hydrogeology The topography of the Site and immediately surrounding area are relatively flat. No surface water bodies or areas of natural or scientific interest are present within 30 metres (m) of the RSC property limits. The geology of the RSC property is shown schematically on Figure 4. Soil at the RSC property consists of a veneer of topsoil approximately 0.3 to 0.4 metres (m) thick in areas where remediation activities and the raised road beds for the future residential development have not occurred. The current ground surface in the areas where remediation activities have been completed consists of exposed native clayey silt till and/or silt till. The till is underlain by shale bedrock at depths ranging between 5 and 10 m below ground surface (bgs) at the south and north ends of the RSC property, respectively. The bedrock is interpreted to tilt in a northerly direction. Weathered shale is present Ground water elevation contours and the interpreted ground water flow direction beneath the RSC property are shown on Figure 4. Ground water levels were measured at depths ranging between 0.1 and 10 m bgs. The ground water elevation at MW102 was not included in the interpretation of the flow direction. This well was partially completed in the bedrock aquifer, exhibited much more rapid hydraulic response than the other wells, and was considered to be representative of the bedrock aquifer rather than the till. Ground water flows in a northerly direction at the Site, which is consistent with the interpreted slope of the overburden-bedrock interface, the elevated Niagara Escarpment to the south of the Site, and the location of Lake Ontario to the north of the Site. The horizontal hydraulic gradient ranged between and and the upward vertical hydraulic gradient ranged between 0.44 and The till acts as a confining unit with ground water occurring within the shale bedrock/overburden interface, based on the strong upward hydraulic gradient and observations made during the remedial construction activities. No evidence of ground water infiltration from the overburden was observed during the remedial excavation or soil relocation activities, or during installation of the Site services. These excavations were completed to sufficient depths (up to 6 m bgs) to support the concept that ground water occurs in a confined condition within the shale and that the till acts as an aquitard. Ground water recharge likely occurs in the exposed shale bedrock on the Niagara Escarpment, located approximately 1 kilometre south of the Site. Based on ground water elevation measurements, the piezometric head in the bedrock ground water aquifer is likely strongly influenced by infiltration of precipitation from the Niagara Escarpment. These variations in head likely do not result in significant changes in the distribution of the naturally occurring chemicals MBN Page 3

56 Phase Two Conceptual Site Model Escarpment Vista Estates Inc. 590 Main Street West, Grimsby May 21, 2013 that were identified in the ground water within the till as discussed below because the till acts as a confining layer over the bedrock aquifer. Regulatory Basis Analytical results were compared to the Site Condition Standards (SCS) provided in the MOE document entitled Soil, Ground Water and Sediment Standards for Use Under Part XV.1 of the Environmental Protection Act, dated April 15, The following information and data were considered when selecting the appropriate SCS for the RSC property: The RSC property was historically used for industrial (auto wrecker) and agricultural (remainder of RSC property) purposes. The RSC property will be redeveloped for residential use. The RSC property will be connected to the Town of Grimsby s municipal potable water system. All surrounding properties are connected to either the City of Hamilton s or Town of Grimsby s municipal potable water systems. Two active water supply wells are present at Puddicombe Winery and Farm located to the southwest (hydraulically upgradient) of the RSC property. The water supply wells are used for agricultural purposes. Domestic water for human consumption at this location is supplied by the City of Hamilton. The soil beneath the RSC property is classified as fine- to medium-textured based on field observations and grain size analyses. The ph of the surface soil is between 5 and 9 and the ph of the subsurface soil is between 5 and 11. The Table 4 SCS for residential property use with fine- to medium-textured soil in a potable ground water condition were selected as the appropriate SCS for the RSC property. As discussed below, the entire property meets the Table 2 (full-depth) SCS, except for the railway safety berm, where the Table 4 SCS are required. The Table 4 SCS were used for the entire RSC property to simplify the filing of the RSC. Contaminants of Concern in Soil The soil sampling locations, sampling depths, and COCs that exceeded the Table 4 SCS prior to remediation are shown on Figure 5. Cadmium, lead, zinc, and PHCs were identified as the primary COCs in the area that was formerly used by the auto wrecker. Antimony, arsenic, barium, copper, molybdenum, and vanadium were identified as less prevalent COCs, primarily present at the north end of the former auto wrecker s operation. MBN Page 4

57 Phase Two Conceptual Site Model Escarpment Vista Estates Inc. 590 Main Street West, Grimsby May 21, 2013 An area of DDE-affected soil was identified in the former orchard area. DDE is formed by the breakdown of DDT, a common pesticide that was used in the mid-twentieth century. DDE exhibits limited mobility in soil and was confirmed to be limited to the topsoil. The measured DDE concentrations met the Table 4 SCS for subsurface soil. Contaminants of Concern in Ground Water Monitoring wells locations are shown on Figure 6. No evidence of free product was observed at any of the monitoring wells. No contaminants of concern were identified in ground water at concentrations that exceeded the Table 4 SCS other than cobalt at MW101, MW103, and MW104; sodium at MW103; and uranium at MW101 and MW104. These parameters only marginally exceeded the applicable Table 4 SCS. MW102 was screened partially into the shale bedrock unlike the other wells, which were screened strictly within the overburden. Based on the consistent concentrations across the RSC property (i.e. concentrations were comparable irrespective of past industrial or agricultural use) and anecdotal experience at other sites in the Niagara Region, the marginal exceedances of cobalt and uranium are likely naturally occurring related to the till. Based on the ground water monitoring results, the historical activities that were performed at the RSC property have not caused an adverse effect on ground water quality at the RSC property. The RA was completed by Novatox to evaluate the receptors, exposure pathways, and risk management measures (RMM) to eliminate exposure pathways from the COCs that exceeded the Table 4 SCS. Novatox concluded that the prohibition of water supply wells at the RSC property was sufficient to eliminate the identified exposure pathways associated with these marginal exceedances. Remedial Measures The remedial excavation areas are shown on Figure 7. The method of remediation is also identified for each remedial area. Remedial measures were implemented in order to address the impacts that were identified within the limits of the former auto wrecking operation as well as the area of DDE-affected soil that was identified in the former orchard area. Approximately 2,987 cubic metres of soil with exceedances of the Table 4 SCS for surface soil, containing visible PHC staining or free product, and/or significant quantities of slag was classified as non-hazardous waste in accordance with O.Reg. 558, as amended, and subsequently excavated and disposed off-site at MOE-licensed facilities prior to the commencement of screening activities as described below. Approximately 299 cubic metres of screened soil that did not meet the Table 4 SCS for subsurface soil was disposed off-site at MOE-licensed facilities. Approximately 976 tonnes of deleterious material was disposed off-site at MOE-licensed facilities. Approximately 6,082 cubic metres of material was mechanically screened on-site in order to remove deleterious materials (i.e. scrap metal, tires, windshields, plastic, rubber hoses, etc.) MBN Page 5

58 Phase Two Conceptual Site Model Escarpment Vista Estates Inc. 590 Main Street West, Grimsby May 21, 2013 from the fill material. Screening activities were completed following the excavation and off-site disposal of visibly impacted material (see above). A Powerscreen Horizon 6203 mobile screening plant with Certificates of Approval for air and waste management system was used to screen the material. The screener was moved from the south to north end of the property as screening progressed. Soil from the areas that were designated for screening was moved to the general vicinity of the screener using a bulldozer. Deleterious materials were picked from the soil to the extent practicable prior to loading the soil into the screener using an excavator. Three separate streams were generated by the screening process: 1. Fine-grained material consisting of screened soil. 2. Deleterious debris as described above. 3. Inert solid material (rocks, concrete, etc.). A total of 3,750 cubic metres of soil material was generated by the screening process. The soil stockpiles were field-screened for organic and combustible vapours and sampled in accordance with Schedule E and Table 2 of O.Reg. 153/04, as amended. The stockpile sample locations are shown in general on Figure 8 and in detail on Figures 7A through 7D. Approximately 299 cubic metres of soil was disposed off-site as described below. The remainder of the screened soil was determined to meet the Table 4 SCS for subsurface soil. This screened soil (along with inert solid material described above) was relocated to the railway safety berm that is located at the northwest corner of the Site as described below. The limits of excavation for the DDE affected soil are shown on Figure 7. The topsoil was excavated and re-located to the railway safety berm area for use as subsurface soil. Confirmatory soil samples were collected from the auto wrecker and DDE-affected soil remediation areas in accordance with the requirements of Schedule E and Table 3 of O.Reg. 153/04, as amended. The general soil sample locations are shown on Figure 8. Detailed soil sample locations for the auto wrecker s operation area and the disposition of the soil associated with these samples are provided on Figures 7A through 7D. Detailed soil sample locations for the DDE-affected area are shown on Figure 9. All confirmatory soil samples for the final excavation limits met the Table 2 SCS (same as Table 4 SCS for surface soil). The soil in the railway safety berm meets the Table 4 SCS for surface and subsurface soil, as applicable. The Town of Grimsby and Region of Niagara have issued Draft Plan Conditions that must be met prior to final approval of the Site Plan and residential occupancy of the RSC property. The Draft Plan Conditions require the construction of a railway safety berm at the north end of the properties located on the northwest side of the Site that abut the CN railway. Draft Plan Condition 37 provides the minimum design requirements for the construction of the railway safety berm, including the dimensions. Draft Plan Condition 39 requires restrictive covenants to be registered on title and all agreements of purchase and sale or lease to provide notice to the public that the railway safety berm is not to be tampered with or altered and that the property MBN Page 6

59 Phase Two Conceptual Site Model Escarpment Vista Estates Inc. 590 Main Street West, Grimsby May 21, 2013 owners have sole responsibility for and to maintain the berm to the satisfaction of CN. The limits of the railway safety berm are shown on Figure 10. Figure 10 also identifies the limits of the relocated soil that meets the Table 4 SCS for subsurface soil in plan and profile. The native till (confirmed to meet the Table 4 SCS for surface soil) was excavated to a depth of approximately 5 to 6 m bgs. No ground water infiltration into the excavation was observed in the approximately two weeks required to complete the relocation of the soil and inert material. The relocated soil was placed in the excavation in 0.3 m lifts and nominally compacted using a vibrating sheepsfoot roller. The inert material was placed on top of the relocated soil in order to provide a visual reference for the upper limit of the relocated soil. The relocated screened soil and inert material were covered with at least 2 m of the excavated native till that was excavated as described above. An additional 8,000 cubic metres of soil was imported as grading material as described below. Once the railway safety berm is completed, the relocated screened soil and inert material will be covered by a minimum of 4 m of soil that meets the Table 2 full-depth SCS and Table 4 SCS for surface soil. Draft Plan Condition 39 provides a mechanism to ensure that the soil that meets the Table 4 subsurface soil SCS will remain at least 1.5 m below ground surface as required by O.Reg. 153/04, as amended, by legally requiring the property owners to maintain the berm and not otherwise alter, modify, or damage the berm. The soil across the remainder of the Site meets the Table 2 full-depth SCS and Table 4 SCS for surface soil, so no restrictions on excavation depths for road beds, Site services, building foundations, swimming pools, etc. are required for the remainder of the Site. Therefore, no additional risk management measures are required with respect to soil at the Site. No additional soil remediation activities are required. Fill Material Fill materials consisting of soil, slag, concrete, bricks, scrap metal, and other materials were identified within the footprint of the auto wrecker s operation. Based on observations made during the test pitting and remediation programs, it appears that fill material was imported over time to gradually build up the operation area and bury debris and contamination. The auto wrecker s operation area was noticeably elevated above the surrounding grade by between 0.3 to 1.0 m. The total thickness of fill material ranged between 0.2 and 1.3 m bgs. All fill material was either excavated and disposed at MOE-approved landfill facilities or remediated at the RSC property using the method described above. The remedial excavation extended to the native till within the entire limits of the former auto wrecker s operational area except in isolated areas where the fill was confirmed to meet the Table 4 SCS for surface soil. Approximately 8,000 cubic metres of soil were imported from a borrow area located in Stoney Creek, Ontario for use as grading material in the railway safety berm area following completion of the remedial activities. The soil that was imported from the borrow area was characterized in accordance with Schedule E of O.Reg. 153/04, as amended. The imported soil was determined MBN Page 7

60 Phase Two Conceptual Site Model Escarpment Vista Estates Inc. 590 Main Street West, Grimsby May 21, 2013 to meet the requirements of Section 55 of O.Reg. 153/04, as amended, and was deemed suitable for use as grading material for the construction of the railway safety berm. Human and Ecological Receptors and Exposure Pathways There are no structures at the Site other than the sales office trailer. The parameters that exceeded the Table 4 SCS in ground water (i.e. cobalt, sodium, and uranium) are not considered to be volatile and are not anticipated to represent a potential for soil vapour intrusion into the homes that will be constructed at the Site. NovaTox completed the RA in order to assess the potential risk to human and ecological receptors from exposure to the ground water beneath the RSC property that exhibited slight exceedances of the Table 4 SCS for cobalt, sodium, and uranium in ground water. The human receptors and exposure pathways prior to and after the implementation of the RMM described below are provided on Figures 11 and 12, respectively. Novatox identified the main exposure pathway prior to the implementation of the RMM to be ingestion and dermal contact with ground water by residents if ground water is used as the water supply. NovaTox concluded that these exposure pathways are eliminated if water supply wells are not installed as the properties will be connected to the Town of Grimsby municipal water supply. The ecological receptors and exposure pathways prior to and after the implementation of the RMM described below are provided on Figures 13 and 14, respectively. NovaTox concluded that there are no anticipated significant ecological receptors or exposure pathways prior to or after the implementation of the RMM as the receptors would not come into contact with the affected ground water. Risk Management Measure The installation of water supply wells at the RSC property is the RMM that is specified in CPU XZRRD. No other RMM are required. There will be no monitoring or maintenance of the RMM. All properties where dwellings are to be constructed will be connected to the Town of Grimsby municipal water supply, so water supply wells would not be required nor typically installed in any case. The Certificate of Requirement has been registered on the titles for the parcels that are associated with the RSC property in order to meet the notification requirements as specified in the CPU. Data Gaps and Uncertainty No significant data gaps were identified that would materially affect the findings of the Phase Two ESA CSM. MBN Page 8
