The Phase I-II - Environmental Site Assessment (ESA) update is an update of a previous environmental report prepared by this firm, as detailed below. Site Information The subject site is a rectangular shaped property that is currently vacant and used as a parking lot. The proposed development for the site is a multi-storey residential building. The site is in a municipally serviced area. The purpose of the Phase I portion of the ESA was to review updated historical records and conduct a cursory site inspection. The purpose of the Phase II - ESA update was to compare the previously obtained analytical results to the current MOE Table 3 standards for the proposed residential development. Ottawa Kingston North Bay

2 Mr. Bruce Greenberg Page 2 File: PE2224-LET.01 Previous Environmental Reports The following report was reviewed: Phase I-II - Environmental Site Assessment, Vacant Land, 490 Preston Street, Ottawa, Ontario, prepared by Paterson Group Inc., dated October 24, 2005 The original Phase I - ESA report identified concerns from the former service station to the northeast, the current dry cleaning facility to the east and, to a limited degree, the former service station to the southeast. A Phase II - ESA was recommended and conducted for the subject property. The Phase II - ESA consisted of placing seven (7) boreholes, one of which was installed with a monitoring well, on the subject property. Concentrations of PAHs and/or metals in excess of the 2004 MOE Table 3 standards for commercial property were identified in three of these boreholes. One (1) groundwater sample was submitted for analytical testing of petroleum hydrocarbons (PHCs F1-F4) and volatile organic compounds (VOCs). No concentrations of any of the analysed parameters were detected in the groundwater and it was in compliance with the 2004 MOE Table 3 standards for commercial property. Phase I - ESA Historical and Records Review Update A City of Ottawa document entitled Old Landfill Management Strategy; Phase 1 - Identification of Sites, City of Ottawa, Ontario ; finalized October 2004, was reviewed as part of the update. A former landfill was identified adjacent to Dow s Lake approximately 100 m south of the subject property. The inferred direction of groundwater flow from the former landfill footprint is towards the nearby Dow s Lake and it is not expected to pose a significant concern to the subject site. No other landfills were identified within 400 m of the subject site. The TSSA, Fuels Safety Branch in Toronto, was contacted electronically on February 3, 2011 to inquire about current and former underground storage tanks (USTs), spills and incidents for the subject site and neighbouring properties. The TSSA has records for 8 removed USTs at 505 Preston Street and for 4 removed USTs at 485 Preston Street. Both properties were formerly occupied by service stations and were identified as environmental concerns in the initial Phase I - ESA. There are no USTs recorded in the TSSA registry for the subject property. No other neighbouring properties are registered with the TSSA. patersongroup

3 Mr. Bruce Greenberg Page 3 File: PE2224-LET.01 The most recent aerial photograph reviewed in the previous report was taken in Aerial photographs taken in 2002, 2005 and 2008 were reviewed as part of the current update. The aerial photos reviewed show no significant changes to the subject site and or neighbouring properties. A search of the MOE Brownfields environmental site registry was conducted on January 25, No record of site conditions (RSC) have been filed with the MOE for any properties within 150m of the subject site. The subject site is not listed in the registry. The document prepared by the Canadian Council of Resource and Environment Ministers, entitled National Inventory of PCB Waste Storage Sites, dated 1988 was reviewed. No PCB storage sites are located within 400 m vicinity of the subject site. Site Visit The Phase I - ESA update site visit was conducted on January 26, 2011 by Paterson personnel from the environmental division. The site visit included a review of the subject site and the adjacent lands and their current use. The sales office trailer on-site was not accessible at the time of the site visit. Exterior Assessment The subject site is currently vacant with the exception of a sales office trailer in the south east corner and is operated as a vehicle parking lot. The site is partly paved with asphaltic concrete and partly gravel-covered. The site is approximately at grade with the adjoining Preston Street and the regional topography is mostly flat. The ground surface on site slopes down toward its centre, where a catch basin is located. No surficial staining or indications of surficial contamination were observed during the exterior assessment of the subject land. It should be noted that the site was snow covered at the time of the site visit. patersongroup

4 Mr. Bruce Greenberg Page 4 File: PE2224-LET.01 Adjacent Properties Land use adjacent to the subject site was as follows: North - vacant, followed by residential and commercial (restaurant); South - Sidney Street, followed by commercial (CIBC) and Carling Ave; East - Preston Street, followed by residential and commercial ( Peloso Cleaners and Den s Garage); West - residential, followed by commercial (Dow Honda). Several monitoring wells were observed on the vacant property located at 505 Preston Street where there was a former service station. The service station that was formerly located at 485 Preston Street is no longer present and the site is now vacant. Assessment A Phase I - Environmental Site Assessment update was carried out for the vacant residential property. This update included the review of updated historical records and a cursory site inspection. The recent site visit and records review did not identify any new environmental concerns with respect to the subject property or neighbouring lands. A Phase II - ESA was recommended in the original Phase I-ESA and conducted for the subject property to address the potential impacts from the former service station to the northeast, the dry cleaning facility to the east and, to a limited degree, the former service station to the southeast. Phase II - Environmental Assessment Update Field Program The initial Phase II - Environmental Site Assessment consisted of a subsurface investigation that was conducted on October 6, 2005 in conjunction with a geotechnical investigation of the site. The investigation consisted of placing seven (7) boreholes (BH1 to BH7) on the subject property, as presented on Drawing PE Test Hole Location Plan enclosed with this letter. patersongroup

5 Mr. Bruce Greenberg Page 5 File: PE2224-LET.01 BH2 to BH6 were completed to depths ranging from 1.5 to 2.3 m below ground surface and were terminated at practical auger refusal. Bedrock was cored from a depth of 1.58 to a depth of 4.65 m in BH1. A total of thirteen (13) soil samples and two (2) rock core samples were recovered from the boreholes. In general, the soil profile consists of asphaltic concrete and/or fill overlying topsoil/peat. The topsoil/peat was underlain by glacial till over bedrock. A groundwater monitoring well was installed in BH1 to assess groundwater quality beneath the subject property. On October 11, 2005, the groundwater level in the monitoring well was measured at 2.4 m below the ground surface. It should be noted that the groundwater level will fluctuate seasonally. Remediation Criteria In the original report, the soil and groundwater remediation criteria for the subject property were obtained from Table 3 for Commercial Property use from the document titled Soil, Ground Water and Sediment Standards for Use Under Part XV.I of the Environmental Protection Act, prepared by the Ontario Ministry of Environment (MOE), March, The proposed development on the subject site requires a land use change to residential property. As part of the current update, the soil and groundwater test data for the subject property was reassessed using Table 3 of the document titled Soil, Ground Water and Sediment Standards for Use Under Part XV.I of the Environmental Protection Act, prepared by the Ontario Ministry of Environment (MOE), July, The selected MOE Standards are based on the following considerations for the subject site: Coarse grained soil conditions. Surface soil and groundwater conditions. Non-Potable groundwater situation. Residential land use. It should be noted that the depth of the bedrock across the subject site is currently less than 2 m, however the proposed development will require an excavation into bedrock to a depth of approximately 14 m. As such the MOE Table 3 Standards are selected as the remediation criteria. patersongroup

6 Mr. Bruce Greenberg Page 6 File: PE2224-LET.01 It is our understanding that the subject property will be re-developed in the near future, which will involve the complete removal of all soil from site. Any soil removed from site, which has contaminant concentrations in excess of the MOE Table 1 Standards, will require disposal at an MOE approved facility. The MOE Table 1 Standards are presented herein for comparison purposes. Paracel Laboratories (Paracel) of Ottawa, performed the laboratory analysis of the soil and groundwater samples submitted for analytical testing. Paracel is a member of the Standards Council of Canada/Canadian Association for Environmental Analytical Laboratories (SCC/CAEAL). Paracel is accredited and certified by SCC/CAEAL for specific tests registered with the association. Analytical Results Soil During the initial Phase II - ESA, three (3) soil samples were submitted for analytical testing of metals and/or polycyclic aromatic hydrocarbons (PAHs). The test results are presented in Tables 1 and 2 and are compared to the 2009 MOE Table 1 and Table 3 Standards. A copy of the laboratory s certificate of analysis is included in this letter. The three (3) soil samples submitted for analysis were collected from the fill materials at depths ranging from 0.8 to 1.4 m. In summary, concentrations of antimony, barium, boron, copper, lead, mercury, selenium and/or zinc exceeding the MOE Table 3 Standards were identified in the soil samples from BH2 and BH3. A boron concentration of 4 µg/g, which slightly exceeds the MOE Table 3 Standard for a residential property of 1.5 µg/g, was identified in the soil sample from BH6. Concentrations of molybdenum which exceeds the MOE Table 1 standard for a residential property was also identified in BH3. Concentrations of various PAHs exceeding the MOE Table 3 Standards for a residential property were identified in the soil sample from BH2. patersongroup

9 Mr. Bruce Greenberg Page 9 File: PE2224-LET.01 Groundwater A groundwater sample was collected on October 11, 2005 from the monitoring well installed in BH1 and submitted for analytical testing of petroleum hydrocarbons (PHCs F1- F4) and volatile organic compounds (VOCs). The groundwater is in compliance with both the incoming MOE Table 1 and Table 3 standards for a residential property. A copy of the laboratory certificate of analysis is included in this letter. (The analytical test results are not presented in tabular format since no concentration of any of the parameters analysed was reported by the laboratory above its method detection limits.) Assessment A Phase I-II Environmental Site Assessment update was conducted for the property located at 500 Preston Street, in the City of Ottawa. The purpose of the Phase I portion of the ESA was to review updated historical records and conduct a cursory site inspection. The purpose of the Phase II - ESA update was to compare the previously obtained analytical results to the incoming MOE Table 3 standards for the proposed residential development. The Phase I - ESA update did not identify any new environmental concerns with respect to the subject property or neighbouring lands. Soil The Phase-II ESA was completed in October, 2005, in which seven (7) boreholes were completed on site. Three (3) soil samples collected from the fill materials at depths ranging from 0.8 to 1.4 m in BH2, BH3 and BH6 were submitted for analytical testing of metals. Olfactory evidence of polycyclic aromatic hydrocarbons (PAHs) was also observed in BH 2 and as such this soil sample was also submitted for analytical testing of PAHs. In summary, concentrations of antimony, barium, boron, copper, lead, mercury, selenium and/or zinc exceeding the incoming MOE Table 3 residential standards were identified in the soil samples from BH2 and BH3. A boron concentration of 4 µg/g, which slightly exceeds the MOE Table 3 Standard for a residential property of 1.5 µg/g, was identified in the soil sample from BH6. A concentration of molybdenum which exceeds the MOE Table 1 standard for a residential property was also identified in BH3. patersongroup

10 Mr. Bruce Greenberg Page 10 File: PE2224-LET.01 Concentrations of various PAHs exceeding the MOE Table 3 Standards for a residential property were identified in the soil sample from BH2. Based on the findings of the Phase I-II-ESA, it is our opinion that the soil in the area of BH2 and BH3 has been impacted by PAHs and/or metals and will require remediation. Groundwater No concentration of any of the parameters analysed was reported by the laboratory above its method detection limits. The groundwater results comply with the incoming MOE residential standards. Recommendations It is recommended that an environmental remediation program be undertaken to clean up the soil to MOE Table 3 Standards. This may be completed during the re-development of the site, at which time it is expected that all soil will be removed from the site. Any soil removed from site, which has contaminant concentrations in excess of the MOE Table 1 Standards, will require disposal at an MOE approved facility. It is recommended that a representative from Paterson be present at the time of the removal of the impacted soil to provide direction and to obtain confirmatory soil samples upon the completion of the remediation program. patersongroup
