16 Qualified Person s Statements and Certifications 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 2012/09/21, 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. Ground water sampling has been conducted in accordance with the regulation by or under the supervision of a qualified person as required by the regulation. As of 2012/09/21, in my opinion, based on the phase one and phase two environmental site assessments and any confirmatory sampling, the RSC property meets the applicable full depth generic site condition standards prescribed by section 36 of the regulation for all contaminants prescribed by the regulation in relation to the type of property use for which this RSC is filed, except for those contaminants (if any) specified in this RSC at Table 2, Maximum Contaminant Concentrations Compared to Standards Specified in a Risk Assessment. As of 2012/09/21, the maximum known concentration of each contaminant in soil, sediment and ground water at the RSC property for which sampling and analysis has been performed is specified in this RSC at Table 1, Maximum Contaminant Concentrations Compared to Applicable Site Condition Standards. In relation to any contaminant excepted from the certification mentioned above as specified in the RSC at Table 2, Maximum Contaminant Concentrations Compared to Standards Specified in a Risk Assessment, or in relation to any other contaminant that in my opinion is likely to cause an adverse effect: A risk assessment was prepared for the contaminant with respect to the property for which the phase two environmental site assessment was conducted. The Director has accepted the risk assessment under clause (1) (a) of the Act. As of 2012/09/21, the property for which the phase two environmental site assessment was conducted meets the standards specified in the risk assessment for the contaminant. I am a qualified person and have the qualifications required by section 5 of the regulation. I have in place an insurance policy that satisfies the requirements of section 7 of the regulation. I acknowledge that the RSC will be submitted for filing in the Environmental Site Registry, that records of site condition that are filed in the Registry are available for examination by the public and that the Registry contains a notice advising users of the Registry who have dealings with any property to consider conducting their own due diligence with respect to the environmental condition of the property, in addition to reviewing information in the Registry.

A summary of APECs identified at the Site and the corresponding investigative locations at the Site are provided below: Area of Potential Environmental Concern Media Investigated Investigative Locations APEC #1 Historic Chemical Storage/Handling and Associated Known Groundwater Impact APEC #1a Historic Waste Oil/Solvent UST APEC #1b Historic Exterior Chemical Storage Area APEC #1c Historic Interior MDI/TCA ASTs (concrete containment berm) and Chemical Mixing Room (concrete floor) APEC #1d Historic Exterior Freon AST Soil Groundwater Soil Groundwater Soil Groundwater Groundwater (see below for APEC sub areas) MW3S 08, MW3D 08 MW1S 08, MW1D 08, MW3S 08, MW5 08, MW10 09, MW18 09, OW9A 91, OW9B 91, MW103, MW103A&B, MW 102, MW 102A&B MW3S 08, MW3D 08, MW6 08, MW10 09, BH1 11, BH2 11, BH3 11, BH4 11, BH5 11, BH6 11 MW3S 08, MW5 08, MW6 08, MW10 09, MW18 09, OW3A 91, OW3B 91, OW6 91, OW9A 91, OW9B 91, MW103, MW103A&B, MW 102, MW 102A&B MW2 08, MW11S 09, MW11D 09, OW1 91 Soil Groundwater BH5 11 MW 102, MW 102A&B, OW3B 91, OW3A 91 APEC #2 Historic On Site Transformer Use Soil SS (11) 1

At the time of groundwater sample collection ( ), a Table 6 Standard for hexane had not been published by the MOE. Hexane was not detected in the soil sample analytical results summarized in the Update Phase Two ESA and hexane was not identified as a specific contaminant of concern during the Update Phase One ESA. The groundwater parameters included in the VOC analysis were deemed sufficient to adequately characterize groundwater quality at the Site. The groundwater sample analytical results that were generated to investigate APEC #1 (historic chemical storage/handling and associated known groundwater impact) did not include analysis for petroleum hydrocarbons (PHCs) or polycyclic aromatic hydrocarbons (PAHs). Soil samples that were collected to investigate APEC #1 were analyzed for PHCs and PAHs and no exceedences of the MOE Table 6 Standards were identified at the Site. The groundwater analysis at the Site was subsequently limited to VOCs. A total of 23 groundwater monitoring wells were installed at the Site to investigate groundwater conditions. One monitoring well, MW18 09, was constructed with a well screen measuring 4.6 metres in length, which is longer than the maximum well screen length (3.1 metres) specified in O. Reg. 153/04. CRA understands that the potential for groundwater sample dilution is the concern that underlies the O. Reg. 153/04 well screen length requirement. The other 22 monitoring wells have screen lengths of 3.1 metres or less. Monitoring well MW18 09 was installed prior to this O. Reg. 153/04 requirement. The screened interval for MW18 09 spans a continuous sand layer, with no seams that would prevent the vertical migration of impacts. Shallow groundwater impacts were identified up gradient of MW18 09 (at MW10 09) and deep groundwater impacts were identified down gradient of MW18 09 (at MW103A, MW102A, and MW102B). On this basis, there should be no concern with clean groundwater entering the well over a portion of the well screen length and diluting the sample. Notwithstanding the above, CRA undertook to evaluate the possibility that clean groundwater had diluted the groundwater samples collected from MW18 09 due to its well screen length. CRA assessed the most recent groundwater quality data from this monitoring well on the assumption that 1.5 metres of well screen was contributing clean groundwater (i.e., no impact). To evaluate this scenario, the following equation was applied to the analytical results: (11) 2

30 Based on the above formula, the measured concentrations and adjusted concentrations for the COCs at MW18 09 are summarized below. The Property Specific Standards (PSS) that were generated during the Risk Assessment for the Site are also provided in the below table for reference. Parameter Measured Concentration (µg/l) Adjusted Concentration (µg/l) Risk Assessment Property Specific Standard (µg/l) 1,1,1 Trichloroethane ,1 Dichloroethane ,1 Dichloroethene Vinyl Chloride As shown in the above table, the adjusted concentrations for all measured parameters remain below the PSS that were generated during the Risk Assessment for the Property. This demonstrates that even if clean groundwater entered the well over 1.5 metres of well screen, the concentrations of contaminants in groundwater screened by the remaining 3.1 metres of well screen met the PSS. CRA also notes that groundwater investigations and monitoring have been conducted at the Site since 1992, a period of over 20 years. Groundwater quality at the Site is clearly improving over time and is very well understood. Given that only one monitoring well had a screen length in excess of the current requirement it is the QP s opinion that the characterization of groundwater quality at the Site is appropriate. Potential Contaminant Distribution and Transport Pathways Below grade utilities (storm sewers) may represent potential preferential pathways for contaminant migration; however, since the groundwater table is generally greater than 2 metres below ground surface (m bgs), and the on Site storm sewers discharge into a surface ditch located east of the Site, it is unlikely that the storm sewers would be located within the groundwater table. The locations of the on Site below grade utilities are shown on Figure (11) 3

31 Overburden Geology Based on the field activities undertaken at the Site (Update Phase Two ESA activities and previous environmental investigations), the following geologic deposits were encountered, in descending order, at the Site: Surficial Asphalt/Concrete Sand and Gravel Fill Sand or Silt and Sand Silty Clay or Silt and Clay (discontinuous aquitard) Sand Tavistock Till (aquitard) A summary of the on Site stratigraphy is provided below. The stratigraphy encountered at the Site generally consisted of surface asphalt or concrete underlain by sand and gravel fill that extended to depths ranging from 0.6 to 4.0 m bgs. The sand and gravel fill was underlain by moist to wet fine grained sand, or silt and sand, which generally extended to depths ranging from 3.4 to 5.2 m bgs (shallow perched aquifer). The sand, or silt and sand, layer was generally underlain by a discontinuous layer of dry, stiff, silty clay or silt and clay (discontinuous aquitard). This silty clay layer was not encountered at borehole MW18 09, where the sand and silt layer extended to a depth of 10.7 m bgs. The silty clay layer referenced above ranged in thickness from 1.4 to 4.2 m. The silty clay layer was underlain by a moist to saturated sand layer that ranged in thickness from 1.2 to 3.3 m (defined as the deep aquifer). The sand layer was underlain by a dry silty clay layer or dry clay with silt layer (Tavistock Till, as noted below) that extended to the maximum depth of investigation. The Tavistock Till unit was encountered at borehole/monitoring well locations in all areas of the Site, including MW3D 08, MW18 09, and OW3A 91 (shown on Figure 11), and OW6 08, OW9B 91, MW10 09, MW18 09, MW11 D 09, and OW1 91 (as shown on Figure 12). The Tavistock Till unit is denoted by either CL (TILL) or CL/ML (TILL) on Figure 11 and Figure 12. The characteristics of the Tavistock Till and its Regional extents are further discussed below (11) 4

32 The Site is underlain by glacial till mapped as the Tavistock Till (Karrow, , 1993a 2, 1993b 3 ). To the east of the Site, the underlying glacial till is mapped as the Port Stanley Till (Karrow, 1993a). The Port Stanley Till overlies the Tavistock Till in this area (Karrow, ). Both of these till units are regionally extensive, with mapped extents of kilometers to tens of kilometers. The Tavistock Till is generally a gritty clayey silt till, while the Port Stanley Till is a sandy to silty till. Estimates of hydraulic conductivity of the Tavistock Till and Port Stanley Till from literature are in the range of 10 7 to 10 8 cm/sec (Freeze & Cherry, ). CRA identified seven off Site water well records that are associated with properties located within a 650 metre radius of the Site (MOE, ). Tavistock and/or Port Stanley Till was identified at depths ranging from 4.27 to metres below ground surface (mbgs) in each of the water well records. The thickness of the till unit(s) ranged from to metres at each location. CRA advanced a borehole into the Tavistock Till unit in the vicinity of the historic waste oil underground storage tank (MW3D 08), which is believed to be the primary source area. The borehole was advanced a distance of 5.8 m into the till unit (to a depth of 10.7 m bgs) and a deeper groundwater bearing unit was not identified. CRA collected a soil sample from 6.1 to 7.6 m bgs (1.2 to 2.7 m into the till unit) and the COCs were not detected at the laboratory method detection limits. Based on the thickness of the till unit and the lack of groundwater encountered, it was decided not to extend the boring further. In summary, Tavistock Till and Port Stanley Till materials were identified at borehole/monitoring well locations in all areas of the Site and the Tavistock Till and Port Stanley Till units are regionally present in the vicinity of the Site based on the water well records from seven off Site locations. Assessing all of this information, it can be concluded with certainty that the Tavistock Till unit is present and continuous across the Site. The thickness of the Tavistock and/or Port Stanley Till material in the immediate vicinity of the Site is documented to be substantive, in the range of 19 to 40 metres. Considering the thickness of the till and its hydraulic conductivity, the Karrow, P.F., Quaternary Geology of the Cambridge Area, Ontario Geological Survey Map 2508, Scale 1:50,000.

33 till unit is acting as an aquitard to prevent the vertical migration of contaminants to deeper groundwater at the Site. Due to the presence of the till aquitard unit across the Site, no additional evidence that would further the understanding of the distribution of contaminants at the Site would be gained by completing additional deeper investigations at the Site. Two geologic cross sections were developed for the Site. The locations of the geologic cross sections are shown on Figure 5. Geologic cross sections A A' and B B' are shown on Figure 6 and Figure 7, respectively. These cross sections depict the generalized extent of the fill and native soil units. Elevations of the extents of the geologic units are displayed on the cross sections in metres above mean sea level (m AMSL). Hydrogeological Characteristics As discussed above, the shallow and the deep aquifers are separated on the Site by a discontinuous dry, stiff, silty clay or silt and clay which acts as a shallow aquitard in the areas that it is present. This shallow aquitard was not encountered in the vicinity of MW18 09, which facilitated the migration of the shallow groundwater impact in the source area (former waste oil/solvent UST) into the underlying deep groundwater on the Site. The groundwater impact extends off Site in this deep groundwater aquifer. The deep groundwater aquifer is underlain by a silty clay till (Tavistock Till aquitard), which prevents any further vertical migration of the groundwater impact. Depth to Bedrock Bedrock was not encountered during field activities conducted at the Site. Based on the review of off Site water well records that are associated with properties located within a 650 metre radius of the Site (MOE, ), bedrock is located approximately 49 m bgs in the vicinity of the Site. Depth to Groundwater and Flow Direction Groundwater is present at the following depths at the Site: The shallow aquifer is present at depths ranging from 1.53 to 3.71 m bgs The deep aquifer is present at depths ranging from 2.29 to 7.57 m bgs The on Site shallow and deep groundwater aquifers are interpreted to flow in an approximately easterly direction. The interpreted groundwater flow directions have been consistent since first evaluated in Shallow and deep groundwater contours are provided on Figure 8 and Figure 9, respectively (11) 6

34 The horizontal hydraulic gradient for the Site is approximately m/m. horizontal groundwater flow velocity is 1.8 m/year. The estimated The vertical hydraulic gradient is estimated to be 0.17 downward. Applicability of O. Reg. 153/04, Section 41 or 43.1 Based on the results of the Update Phase One ESA and Update Phase Two ESA, the Site is not considered environmentally sensitive, as defined in O. Reg. 153/04, Section 41. Based on the geology encountered during the Update Phase Two ESA, the Site was not determined to be a shallow soil property or located within 30 metres of a water body, as defined in Section 43.1 of the Ontario Regulation 153/04; however, due to the shallow depth to groundwater (less than 3 mbgs), the use of the generic MOE Table 2 Standards would not be considered to be sufficiently conservative for the Site. As a result, CRA assessed the soil and groundwater analytical data generated in the Update Phase Two ESA with respect to the MOE Table 6 Standards, which assume that the depth to groundwater is less than 3 mbgs. Areas Where Soil has Been Brought from Another Property CRA did not identify any areas at the Site where soil has been brought from another property. Proposed Buildings and Structures The locations of proposed buildings and structures on the Site are not currently known. The locations of existing buildings that were present at the Site at the time of the Update Phase Two ESA are shown on Figure 10. Contaminant Distribution in Soil and Groundwater No Contaminants of Concern (COCs) were identified in soil. The following compounds are identified as COCs in on Site groundwater since they were either detected at concentrations greater than the MOE Table 6 Standards, or were not detected at a laboratory method detection limit that was greater than the MOE Table 6 Standards: 1,1,1 trichloroethane 1,1,2 trichloroethane 1,1 Dichloroethane 1,1 Dichloroethene (11) 7

35 1,2 Dibromoethane (Ethylene dibromide) Tetrachloroethane Trichlorofluoromethane (Freon 11) A summary of the groundwater concentrations measured above the MOE Table 6 Standards is provided in plain view on Figure 10. The areas of groundwater contamination at the Site is estimated to be 13,337 m 2 (shallow groundwater) and 18,114 m 2 (deep groundwater), as shown on Figure 10. Cross section locations are shown on Figure 5. Cross sections illustrating the vertical extent of the groundwater concentrations measured above the MOE Table 6 Standards are presented on Figure 11 and Figure 12. As previously discussed, Tavistock Till and Port Stanley Till materials were identified in all areas of the Site and are regionally present in the vicinity of the Site. The thickness and estimated hydraulic conductivity of the Tavistock and/or Port Stanley Till material in the immediate vicinity of the Site is deemed to be sufficient to act as an aquitard to prevent the vertical migration of contaminants at the Site. The vertical extent of groundwater impact, as shown on Figure 11 and Figure 12, is defined by either groundwater analytical results or the presence of the Tavistock Till (aquitard), from which a soil sample was collected in the former source area and no COCs were detected. The source of the COC impacts in groundwater is believed to be the former use and storage of these chemicals during historical operations at the Site. Specifically, the primary source of groundwater impact at the Site was identified to be the historic presence and use of a waste oil underground storage tank (UST) at the Site. The location of the former waste oil UST is shown on Figure 10. The groundwater impact has migrated east from the waste oil UST, following the direction of groundwater flow at the Site. The groundwater impact extends off Site to the east. Based on groundwater monitoring that has been conducted at the Site since 1992, there has been a significant decline in chlorinated VOC concentrations at the Site over time, including 1,1,1 trichloroethane, the primary historic contaminant. Residual levels of 1,1,1 trichloroethane and its degradation products, including 1,1 dichloroethane, 1,1 dichloroethene, and vinyl chloride remain in on Site groundwater at low concentrations, but above the Table 6 Standards. The source area for the groundwater impacts, the waste oil UST, was removed from the Site (11) 8

36 approximately 15 years ago. The impacts in soil were also removed during the excavation of the waste oil UST. Recent soil sampling in the vicinity of the former waste oil UST has confirmed that soil impacts do not exist in the area of the former waste oil UST or anywhere else on the Site. Given that a continual source that could contribute to the groundwater impacts is not present, and based on the historical groundwater monitoring conducted at the Site that indicates a significant reduction in chlorinated VOC concentrations, it is expected that the residual groundwater impacts are likely to decline further under naturally occurring conditions. No climatic or meteorological conditions to have influenced the distribution and migration of the groundwater impacts at the Site. Potential Sources of COCs in Groundwater The historic source of the COCs impacts in groundwater is believed to be the former use and storage of these chemicals during historical operations at the Site, including the former waste oil UST. No potential sources of the COCs remain at the Site. Potential for Vapour Intrusion into Site Building Several VOCs were identified in groundwater at the Site at concentrations greater than the MOE Table 6 Standards, including from groundwater samples in the vicinity of the current building. Vapour intrusion from VOCs into the indoor air space of the building could be a possibility. The existing Site building contains no basement, no crawl spaces, and no known underground utility corridors. The floor of the existing building is slab on grade concrete. The building is equipped with two roof mounted HVAC units for heating and cooling purposes; however, the HVAC units have not been operational since they were disconnected in The potential for vapour intrusion into the air space of the existing building and future buildings was addressed in the Risk Assessment for the Site. Based on the results of the Risk Assessment, the following Risk Management Measures (RMMs) that are associated with the vapour intrusion pathway will be implemented at the Site: Any new slab on grade building(s) to be constructed with a minimum volume of at least 9,620 cubic metres as long as the COCs in groundwater remain at the Property A groundwater monitoring program will be implemented for a minimum period of 2 years The construction of building(s) with basements or occupied below grade structures on the Property is prohibited A indoor air monitoring program will be implemented for a minimum period of one year in any existing or new below grade structure not intended for occupancy (11) 9

37 Further details regarding the RMMs for the Site are provided in CPU Number HRQ, issued January 17, Potential Exposure Pathways for Human and Ecological Receptors The potential exposure pathways for COCs in groundwater at the Site are presented on three figures. Human receptors are evaluated on Figure 13, and ecological receptors are evaluated on Figure 14 (terrestrial receptors) and Figure 15 (aquatic receptors). The potential exposure pathway figures identify the following: Contaminant release mechanisms Transport pathways Human and ecological receptor locations on and off Site Receptor exposure points Routes of exposure Figure 13 presents an evaluation for potential human receptors that may be exposed to groundwater. The Site was historically utilized for industrial purposes and will continue to be used for commercial purposes in the future. Thus, the identified receptors include an industrial/commercial worker and a construction/utility worker. Figure 14 presents an evaluation for potential terrestrial receptors that may be exposed to groundwater. The potential terrestrial ecological receptors considered for the Site included terrestrial vegetation, invertebrates, mammals, and birds. Figure 15 presents an evaluation for potential aquatic receptors that may be exposed to groundwater in the event that shallow groundwater COCs from the Site discharge to surface water. The potential aquatic ecological receptors considered for the Site included terrestrial vegetation, invertebrates, mammals, birds and fish. Potential exposure pathways for human and ecological receptors were evaluated in detail in the Risk Assessment for the Site, including the determination of whether or not each of the pathways presented on Figures 13 through 15 are complete (11) 10
