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 2013/12/16, 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. I have, within the six months immediately before the submission of this record of site condition, given written notice of intention to apply non-potable ground water site condition standards to the clerk of the local municipality in which the property is located and the clerk of any upper-tier municipality in which the property is located. As of 2013/12/16, 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 37 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 2013/12/16, 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. 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. The opinions expressed in this RSC are engineering or scientific opinions made in accordance with generally accepted principles and practices as recognized by members of the environmental engineering or science profession or discipline practising at the same time and in the same or similar location.

APEC-2 Central part of the Site 28 : Gasoline and Possible OnSite PCA Associated Products A gasoline storage tank was listed in the Storage in Fixed Tanks EcoLog ERIS database search of Anderson Storage Tank (TANK), dated 4/11/1936, permit type BP A58971, at 2803 Dundas St. W.. The Phase One Environmental Site Assessment by APEC LOCATION OF APEC ON SITE PCA (O.Reg. 153/04 Table 2) CONTAMINANT OF POTENTIAL CONCERN MEDIA POTENTIALLY IMPACTED 30 : Importation of Fill OnSite PCA Material of Unknown TIL conducted a remedial excavation on September 1, 2011 to remove the underground Quality storage tank (UST). The tank was located north of the Phase One Property. Verification samples were taken and concentrations were below Table 3 Standard Criteria. However, the excavation extended into the Site and quality of imported material was not verified – though it contained silty sand with some gravel. Metals & Inorganics Soil 28 : Gasoline and OnSite PCA Associated Products The verification samples were taken from the Storage in Fixed Tanks excavation north of the Site after the UST was removed. The quantity of verification samples were adequate for the excavation conducted on the property to the north of the Site. However, the excavation extended into the Site, but the quantity of verification samples did not meet the requirements of the RSC property. Therefore, additional verification samples are required to meet Ontario Regulation 153/04, Records of Site Condition, Table 3 – Minimum Conformation Sampling Requirements for Excavation. PHC, BTEX Soil, Groundwater LOCATION OF PCA Shaheen & Peaker, dated November 13, 2006 indicated vent pipes and an underground storage tank north of the Site. The environmental soil and groundwater investigation by Shaheen and Peaker, dated November 3, 2006, identified hydrocarbon odour at borehole BH4, between depths of 2m to 4m below ground surface. Due to the inadequate scale on the provided drawing in the report, it is unclear if the borehole was located just north of the central part of the Site, just south of the UST or within the Site.

Phase Two Conceptual Site Model 6.10.1. Description and Assessment Toronto Inspection Limited (TIL) was retained by TAS 2803DSW CORP. to conduct a Phase Two Environmental Site Assessment (Phase Two ESA) for the property with legal description Part 3 of PIN 21355-0270 (LT) Part of Lots 1, Lot 2 and 3, Plan 985 West Toronto Junction and Part of Lot 4, Plan 985 West Toronto Junction, as in CT275451, designated as Part 3 on Plan 66R-_________, City of Toronto, having municipal addresses 2789 Dundas Street West and 2803 Dundas Street West, Toronto, Ontario, together hereinafter referred to as the Site. The purpose of this Phase Two ESA was to ascertain the subsoil and groundwater conditions at the site due to APECs identified in the Phase One ESA and to support filing a Record of Site Condition (RSC) to convey the lands to the City of Toronto, as part of lane widening of the existing laneway south of the Site, resulting in a change in landuse of commercial to community. However, City of Toronto requires that the lands to be conveyed to the City meet the applicable MOE Generic Site Condition Standard for the most environmentally sensitive adjacent land use. (Ref : Directive No. ENV-01-2013 Rev. 1, August 21, 2013, Environmental Site Assessment for Land Conveyances). Since the adjacent lands are residential, a Record of Site Condition will be required for residential land use. The Site is a 1.98m wide strip along the south end of the properties with municipal addresses 2789 Dundas Street West and 2803 Dundas Street West, Toronto, Ontario. The Site is located in a commercial/residential zoning area. Local topography has a mild slope in the southerly direction. At the time of the Phase Two ESA, the Site was vacant and undeveloped, with storage containers occupying much of the Site. As informed by the owner's agent, the Site, along with the larger property to the north, was used as a flea market during the weekends. A chain link fence and block retaining wall are present along the south and east perimeters. The surface cover is gravel and asphalt, with isolated areas having concrete slabs from the former buildings. TIL has used the below conditions established in Ontario Regulation 153/04, as amended, Soil, Ground Water and Sediment Standards for Use Under Part XV.1 of the Environmental Protection Act to determine the applicable Site Condition Standard for the Phase Two property. Table 6.10.1-1 : Site Condition Standard Selection Condition Evaluation Current land use Commercial. Proposed land use Residential (City of Toronto requirement). Area of natural significance The Site is not included nor is adjacent to an area of natural significance nor is part of such an area nor does it include land that is within 30m of an area of 3190-13-E-TAS-E RSC PHASE TWO ESA – 2789-2803 DUNDAS ST W, TORONTO PAGE 30 OF 45 Toronto Inspection Ltd Condition Evaluation natural significance nor part of such an area. Proximity to surface water The Site does not include all or part of a water body nor is adjacent to water body body nor includes land that is within 30m of a water body. pH of soil Potable or Non Ground Water Accredited laboratory chemical test results indicated that the surface (1.5m depth) soil at the property has a pH value between 5 and 9 and the sub-surface (greater than 1.5m depth) soil has a pH value between 5 and 11. Potable The Site and properties within the Study Area are serviced by municipal water supply. Letter of Intent by TIL to use Non-Potable Ground Water for the Site to City of Toronto was provided on March 11, 2014. Depth to bedrock Based on the Phase Two investigation, the depth to bedrock is greater than 2m and shallow soil was not observed on 1/3 or more of the Site. Soil texture Based on the observed sub-surface soil at the Site, native clayey silt and sand deposits were encountered at the boreholes. Coarse texture criteria has been used due to sand being the predominant soil. Based on the above statements, Ontario Regulation 153/04, as amended, Table 3 : Full Depth Generic Site Condition Standards in a Non-Potable Ground Water Condition for Residential/Parkland/Institutional property use with coarse textured soils (Table 3 Standard Criteria) has been used. 6.10.1.1. Areas of Potentially Contaminating Activity Based on the information obtained through our records review, and the visual observations recorded during our site reconnaissance, the Phase One ESA has revealed several Potentially Contaminating Activities (PCAs) within the Study Area. Identified PCAs are indicated in the Phase One Conceptual Site Model, Figure No. 1. Based on an inferred southerly groundwater direction PCAs that pose an environmental concern onto the Site are summarized in the table below and on the following page : Table 6.10.1.1-1 Areas of Potentially Contaminating Activity Ont. Reg. 153/04 as amended Table 2 PCA Activity Site 10 : Commercial Autobody Shops Automotive related services and repairs (tire service, motorcycle) were carried out at 2803 Dundas St W, from 1926 to 2005 and at 2789/2797 Dundas St W, from 1966 to 2005. 30 : Importation of Fill Material of Unknown Quality Parts of the Site were first developed in the late 1800s to early 1900s, with the full development occurring circa 1930s. Therefore, there is potential for unknown quality of fill material on the Site which may be of environmental concern. 3190-13-E-TAS-E RSC PHASE TWO ESA – 2789-2803 DUNDAS ST W, TORONTO PAGE 31 OF 45 Toronto Inspection Ltd Ont.

The Phase One Environmental Site Assessment by Shaheen & Peaker, dated November 13, 2006 indicated vent pipes and an underground storage tank at the central south portion of the property to the north of the Site. The environmental soil and groundwater investigation by Shaheen and Peaker, dated November 3, 2006, identified hydrocarbon odour at borehole BH4, between depths of 2m to 4m below ground surface. Due to the inadequate scale on the provided drawing in the report, it is unclear if the borehole was located just north of the central part of the Site, just south of the UST or within the Site.

Automotive related services and repairs (tire service, motorcycle repairs) were carried out at 2803 Dundas St W, from 1926 to 2005 and at 2798 Dundas St W, from 1966 to 2005. Therefore, there is potential for PHC, VOC related impacts in the soil and groundwater on the Site. Parts of the Site were first developed in the late 1800s to early 1900s, with the full development occurring circa 1930s. Therefore, there is potential for unknown quality of fill material on the Site which may be of environmental concern. Several PCAs were identified in the Fire Insurance Plan of 1964, City Directories and EcoLog ERIS database searches, all of which are indicated in the Phase One Conceptual Site Model Figure No. 1. Properties of potential environmental concern are summarized in the PCA table in the previous section. Due to proximity and inferred groundwater flow in the southerly direction, the identified PCAs may impact the groundwater conditions of the Site for PHCs and VOCs. 2. APEC-2 : Central part of the Site – due to former UST north of the Site. A gasoline storage tank was listed in the EcoLog ERIS database search of Anderson Storage Tank (TANK), dated 4/11/1936, permit type BP A58971, at 2803 Dundas St. W.. The Phase One Environmental Site Assessment by Shaheen & Peaker, dated November 13, 2006 indicated vent pipes and an underground storage tank north of the Site. The environmental soil and groundwater investigation by Shaheen and Peaker, dated November 3, 2006, identified hydrocarbon odour at borehole BH4, between depths of 2m to 4m below ground surface. Due to the inadequate scale on the provided drawing in the report, it is unclear if the borehole was located just north of the central part of the Site, just south of the UST or within the Site. TIL conducted a remedial excavation on September 1, 2011 to remove the underground storage tank (UST). The tank was located north of the Phase One Property. Verification samples were taken and concentrations were below Table 3 Standard Criteria. The excavation extended into the Site and quality of imported material was not verified, as it was obtained from a quarry and considered inert – though it contained silty sand with some gravel. The verification samples were taken from the excavation north of the Site after the UST was removed. The quantity of verification samples were adequate for the excavation conducted on the property to the north of the Site. However, the excavation extended into the Site, but the quantity of verification samples did not meet the requirements of the RSC property. Therefore, additional verification samples are required to meet Ontario Regulation 153/04, Records of Site Condition, Table 3 – 3190-13-E-TAS-E RSC PHASE TWO ESA – 2789-2803 DUNDAS ST W, TORONTO PAGE 34 OF 45 Toronto Inspection Ltd Minimum Confirmation Sampling Requirements for Excavation.

Physical Setting 6.10.2.1. Stratigraphy An environmental subsoil and groundwater investigation was undertaken on September 22, 2011 with boreholes BH201, BH202 and BH203 being drilled to a depth of 7.2m below existing grade. A supplemental investigation was conducted on July 31, 2013 by drilling boreholes BH13-1, BH13-2 and MW13-3 to depths of 5.1m, 5.1m and 6.1m below grade respectively. With the exception of boreholes BH13-1 and BH13-2, all other boreholes were installed as monitoring wells. Soil profile at boreholes BH201 to BH203 consisted of fill material, consisting of silty sand, clayey silt mixed with some gravel, to depths of 1m to 1.5m below grade underlain by a layer of clayey silt to depths of 2m to 4.5m below grade. Below the clayey silt, sand deposits were encountered at all the borehole locations. At boreholes BH13-1 and BH13-2, fill material was present to depths of 2m to 3.2m below grade. Some grey to black staining mixed with asphalt was observed in the fill layer at borehole BH13-1, within a depth of 1.2m below grade. Below the fill material clayey silt was encountered followed by sand. At the location of borehole MW13-3, fill material (former UST backfill) consisting of silty sand with some gravel was present to a depth of 4.5m below grade. Native sand deposits were contacted below the fill material.

Field readings are listed below and on the following page : Table 6.10.2.2-1 : Groundwater Elevations Well ID Date Ground Elevation [m] Groundwater Levels Depth [m] Elevation [m] Sep 26, 2011 118.05 5.68 112.37 Aug 14, 2013 118.05 5.54 112.51 BH202* Sep 26, 2011 117.95 5.65 112.30 BH203* Sep 26, 2011 117.71 5.25 112.46 MW13-3 Aug 14, 2013 118.00 5.45 112.55 5.35 112.55 BH201 BH304** Aug 14, 2013 117.90 *Boreholes could not be located on August 14, 2013. * Geotechnical borehole conducted by TIL on August 1, 2013. The groundwater elevations indicate a horizontal hydraulic gradient of 0.008 in the southerly direction. Since no exceedances were found in any of the groundwater samples, the vertical hydraulic gradient has not been calculated. The hydraulic conductivity of the native silty sand deposits is expected to be 10 -4 cm/s (10-6 m/s) (Freeze, R.A. and J.A. Cherry. 1979. Groundwater) The regional and shallow groundwater flow at the site is expected to be southerly towards Lake Ontario, located approximately 3.2km from the Site boundary. Based on the water level records in the monitoring wells, the groundwater flow direction in the saturated sand deposits appears to be in the southerly direction. Groundwater contours are indicated in Figure No. 3. 6.10.2.3. Depth to Bedrock According to the Ontario Geophysical Survey “OGS Earth” application, the Phase One Study Area is situated within a stone-poor, sandy silt to silty sand-textured till on Paleozoic terrain. The bedrock geology in the vicinity of the Study area is the Georgian Bay/Blue Mountain/Billings Formation (Collingwood/Eastview Member), generally consisting of shale, limestone, dolostone and siltstone. 3190-13-E-TAS-E RSC PHASE TWO ESA – 2789-2803 DUNDAS ST W, TORONTO PAGE 36 OF 45 Toronto Inspection Ltd A review of the Ontario Geological Survey Map P. 2204, Geological Series, Quaternary Geology of Toronto and Surrounding Area of Southern Ontario indicated that the bedrock elevation is approximately 60m. The boreholes conducted during the Phase Two investigation extended to a maximum elevation of 110.10m. Bedrock was not contacted during the investigation and is expected to be beyond this elevation. 6.10.2.4. Depth to Water Table Ground water levels were recorded between 5.25m to 5.68m below grade at the borehole locations. 6.10.2.5. Risk Assessment Applicability Identified contaminants have been remediated adequately. Therefore, risk assessment is not required and Sections 41 or 43.1 of the Regulation do not apply. 6.10.2.6. Soil From Another Property (Refer to Sections 6.10.3.1 to 6.10.3.5) The area with pH exceedance was backfilled entirely with coarse sand and gravel, Granular B Type material which was obtained from a quarry. At the location of PHC exceedance, Granular B Type material was used to backfill the lower excavation and the original overburden material was used to backfill the upper part of the excavation. Analytical testing for Metals & Inorganics indicated that the imported material met Table 1 : Full Depth Background Site Condition Standard for Residential/Parkland/Institutional/Industrial/Commercial/Community property use for all types of soil texture. Analytical testing for PHC/BTEX parameters was conducted for the onsite overburden material which was used to backfill the upper part of the excavation. The sample met Table 3 Standard Criteria and was suitable for backfill. 6.10.2.7. Proposed Buildings and Other Structures At the time of this Phase Two ESA, it is TIL's understanding that the Site will be conveyed to the City of Toronto as part of lane widening of the existing laneway, south of the Site. 6.10.3. Areas of Contamination 6.10.3.1. Contaminant Areas APEC-1 – no contaminants were found due to former automotive operations and fill material. APEC-2 – unknown backfill and inadequate verification sampling. 3190-13-E-TAS-E RSC PHASE TWO ESA – 2789-2803 DUNDAS ST W, TORONTO PAGE 37 OF 45 Toronto Inspection Ltd Imported silty sand with some gravel, was used to backfill the excavation where a UST was removed, at the north side of the Site, on September 1, 2011. The excavation extended into the Site. The quality of the imported material was unknown, in terms of RSC requirements. This was tested and found to have pH values of 10.4 to 11.5. This area is identified in Figure No. 4, which shows the location of exceedances. The verification samples were taken from the excavation north of the Site after the UST was removed. The quantity of verification samples were adequate for the excavation conducted on the property to the north of the Site. However, the excavation extended into the Site, but the quantity of verification samples did not meet the requirements of the RSC property. Verification sampling conducted on July 31, 2013 indicated Petroleum Hydrocarbon (PHC) F3 (C16-C34) fraction exceeding the Table 3 Standard Criteria, with a concentration of 3000µg/g was found at a depth of 3.8m to 4.0m below existing ground level. This area is identified in Figure No. 4, which shows the location of exceedances. At the other areas of the Site, select soil and groundwater samples tested for parameter groups of Volatile Organic Compounds (VOCs), Polycyclic Aromatic Hydrocarbons (PAH), Petroleum Hydrocarbons (PHC) and Metals & Inorganics met Table 3 Standard Criteria. Trace amounts of PAH were present in the grey to black stained fill material at the location of borehole BH13-1. 6.10.3.2. Contaminants Boreholes BH201, BH202, BH203 were drilled on the Site on September 22, 2011 in APEC-1. Select soil and groundwater samples were analyzed for parameter groups of Metals, Volatile Organic Compounds and Petroleum Hydrocarbons. No contaminants of concern were identified in the test samples, when compared to Table 3 Standard criteria. Boreholes BH13-1, BH13-2 and MW13-3 were drilled on the Site on July 31, 2013. Select soil samples were analyzed for parameter groups of Metals and Inorganics. The samples at BH13-1 and BH13-2 met Table 3 Standard Criteria. Borehole MW13-3 was located within the area where imported material was used to backfill the excavation after removal of a UST, at the north side of the Site. The analyzed soil samples indicated a pH value between 10.4 and 11.5. For Table 3 Full Depth Generic Site Condition Standard to apply the pH value of the soil should be between 5 and 9 for surface soil and between 5 and 11 for subsurface soil. Therefore, the this material was identified as impacted and removed. Additional verification sampling was conducted on July 31, 2013 within the Phase Two property to meet the Regulation requirements for filing the RSC. A total of three samples (Sample A (west floor), Sample B (east floor) and Sample C (MW3-3 - north wall), were collected, in addition to the original W4 (south wall) sample. A duplicate of Sample B, identified as Sample D was also sent as a QA/QC sample. Sample D, had Petroleum 3190-13-E-TAS-E RSC PHASE TWO ESA – 2789-2803 DUNDAS ST W, TORONTO PAGE 38 OF 45 Toronto Inspection Ltd Hydrocarbon (PHC) F3 (C16-C34) fraction concentration of 3000µg/g at a depth of 3.8m to 4.0m below existing ground level. The criteria of Table 3 Standard is 300µg/g. Remedial excavation was conducted on September 16, 2013, wherein the above impacted area was excavated and removed (Section 6.10.3.5). 6.10.3.3. Medium Contaminated Groundwater analysis at the location of borehole BH201, BH202, BH203 and MW13-3 indicated that all parameters met Table 3 Standard Criteria for analyzed parameters of VOC and PHC, as applicable. PHC impact was identified in the soil with concentrations of 3000µg/g at Sample D(duplicate of east wall Sample B) and 1900µg/g at Sample D-1 (confirmation sample of D) at depths of 3.8m to 4m below ground surface. The soil used to backfill the former excavation had pH values of 10.4 to 11.5. All other tested soil samples for Metals & Inorganics, PAH, PHC and VOC met Table 3 Standard Criteria. 6.10.3.4. Description and Assessment The Phase One CSM identified a former UST north of the central south part of the Phase One Property. The environmental soil and groundwater investigation by Shaheen and Peaker, dated November 3, 2006, identified hydrocarbon odour at borehole BH4, between depths of 2m to 4m below ground surface. The location of BH4 was located immediately north of the Site or possibly within the Site. The UST located north of the Phase One Property was removed on September 1, 2011 by TIL. Impacted subsoil with PHC odour and staining was excavated and removed offsite. A total of six confirmation samples, two floor and four wall samples were taken from the excavation. All samples met Table 3 Standard criteria. The excavation was backfilled with imported silty sand with gravel. However, the excavation extended into the Phase One Property. On July 31, 2013, subsoil investigation was conducted at the previous backfill area and the analytical testing indicated that the pH value of the imported silty sand with gravel varied from 10.4 to 11.5. This material was removed during the remediation on September 16, 2013 and was replaced with coarse sand and gravel, Granular B type material (Figure No. 5). Analytical testing for Metals & Inorganics indicated that the imported material met Table 1 : Full Depth Background Site Condition Standard for Residential/ Parkland/ Institutional/ Industrial/Commercial/Community property use for all types of soil texture. Verification samples were obtained on December 13, 2013 from the edges of the excavation to ascertain removal of soils with high pH value. The verification samples had pH values between 7.98 and 8.08, thus applicable for Table 3 Site Condition Standard Criteria. 3190-13-E-TAS-E RSC PHASE TWO ESA – 2789-2803 DUNDAS ST W, TORONTO PAGE 39 OF 45 Toronto Inspection Ltd On July 31, 2013 additional investigation was conducted to meet the PHC verification sampling requirements of the former excavation within the Site. The sampling indicated PHC exceedance at the location of Sample D and D1, which were a duplicate and confirmation samples of Sample B, respectively. Excavation to remediate the vicinity of Samples D/D1 was undertaken on September 16, 2013. The PHC impacted zone was identified and removed and verification samples were taken for laboratory analysis. All samples met Table 3 Standard criteria (Figure No. 5). Analytical testing was undertaken on December 13, 2013 for PHC/BTEX parameters for the onsite overburden material which was used to backfill the upper part of the excavation. The sample met Table 3 Standard Criteria and was suitable for backfill. 6.10.3.5. Distribution of Contamination The PHC impacted area in the soil within the Site appeared to be confined to within the sand deposit layer, between the depths of 3.8m to 4.0m below the ground surface, in an easterly to southeasterly direction, to an approximate distance of 6m from the impacted sampling point Sample D/D1. The pH impacted material was confined to the former excavation area. The entire excavation area, conducted on September 16, 2013 was approximately 3m wide x 16m long x 4m deep, with the excavation for PHC impacted material being approximately 3m wide x 8m long x 4m deep. 6.10.3.6. Reason for Contamination As indicated in the EcoLog ERIS Anderson Tank (TANK) database search, a tank was installed in 1936 at 2803 Dundas St W, north of the Site. The Phase One ESA by Shaheen & Peaker in 2006 indicated that the use of the UST was discontinued, possibly in 2000. The contamination on the Site was caused by leakage from the aged UST. The soil used to backfill the former UST excavation was obtained from a quarry and contained high pH values. 6.10.3.7. Migration of Contamination The PHC impact, from the former UST located north of the Site, had migrated south into the Site. Remedial excavation conducted on September 16, 2013 indicated that the PHC impact was migrating within the sand deposit, in the east to south easterly direction and between depths of 3.8m to 4.0m below existing ground surface (Figure No. 5 and 6a). Verification sampling conducted during the remediation indicated no detectable concentrations along the south, west and north walls of the excavation, where the soil samples consisted of 3190-13-E-TAS-E RSC PHASE TWO ESA – 2789-2803 DUNDAS ST W, TORONTO PAGE 40 OF 45 Toronto Inspection Ltd clayey silt. Concentration of 65µg/g, PHC Fraction F3, which is below the Table 3 Standard criteria of 300µg/g was detected in the clayey silt sample (EW) along the east wall of the excavation, at a depth of 4m below the existing ground surface. The excavation extended to within 0.25m of the south perimeter of the Site. Based on visual inspection of the soil profile at the time of excavation, the sand seam appeared to be confined within clayey silt layer present along the south portion of the Site, as observed in the excavation. The remedial excavation was confined to within 0.25m from the south perimeter of the Site (Figure No. 5). The soil with high pH values was removed from the vicinity of the Site and therefore migration is not anticipated. Groundwater was recorded at depths of 5.25m or greater, below the existing ground surface. PHC parameters tested in the ground water sample at BH202 and MW13-3 were below laboratory detection limits. Groundwater contamination was not identified. Therefore, migration of contamination through groundwater is not anticipated. Furthermore, it should be noted that there are no utilities location on Site, within the excavated depths. Therefore, migration through utility trenches and/or disturbed soil is not anticipated. 6.10.3.8. Climatic or Meteorological Conditions Groundwater was documented at depths of 5.25m to 5.68m below ground surface during the environmental investigations. The maximum depth of PHC contamination and subsequent remediation extended to a depth of approximately 4m below the ground surface. Therefore, temporal fluctuations in the groundwater are not anticipated to influence the conditions on Site. 6.10.3.9. Soil Vapour Intrusion Identified contamination related to PHC impact has been adequately delineated during this Phase Two ESA. No soil vapour intrusion is anticipated during construction activities in the future. 6.10.3.10. Existing Building Features The Site was vacant/undeveloped and was generally covered with gravel and asphalt at the time of this Phase Two ESA. Storage containers were placed along the central and west part of the Site. A chain link fence was present along to the Site boundaries, with a block retaining wall, 0.6m to 1.5m high was present along the south and east perimeter of the Site. 3190-13-E-TAS-E RSC PHASE TWO ESA – 2789-2803 DUNDAS ST W, TORONTO PAGE 41 OF 45 Toronto Inspection Ltd 6.10.3.11. Building Heating, Ventilation and Air Conditioning The Site was vacant and undeveloped at the time of this Phase Two ESA. 6.10.3.12. Subsurface Utilities At the time of this Phase Two ESA, there were no subsurface utilities. 6.10.3.13. Human & Ecological Receptor Conceptual Model The human and ecological receptor conceptual model is presented in Figure No. 7. 6.10.3.13.1. Release Mechanisms PHC impacts were identified in the subsoils at the Phase Two property. No groundwater impacts were identified. Therefore, soil is considered a release mechanism. Soil with high pH values was removed and is not considered a release mechanism. 6.10.3.13.2. Contaminant Transport Pathway The impacts are transported by infiltration and percolation, through the sand seams under the Phase Two property. The impacts can also be transported as vapours when exposed to air. 6.10.3.13.3. Receptors Potential receptors are excavation workers on site and organisms within the subsoil. 6.10.3.13.4. Receptor Exposure Points Excavation below 3.8m are possible exposure points for above receptors. 6.10.3.13.5. Routes of Exposure The impacted materials were adequately remediated and no routes of exposure are anticipated. However, personal protective equipment should be used by work personnel when handling soils. 3190-13-E-TAS-E RSC PHASE TWO ESA – 2789-2803 DUNDAS ST W, TORONTO PAGE 42 OF 45 N W E S TITLE: 110 Konrad Crescent, Unit 16 Markham, Ontario L3R 9X2 Tel: 905-940 8509 Fax: 905-940 8192 Email : [email protected] Phase One Conceptual Site Model (RSC Site) LOCATION: 2789-2803 Dundas Street West, Toronto, Ontario PROJECT NO. 3190-13-E-TAS-C(RSC) DATE : Sep 2013 FIGURE NO : 01 N W APEC 2 E S Unknown fill/inadequate verification samples BH4 (S&P 2006) (approx.)
