Filed Record of Site Condition # 216554 on 2015/02/10 14 of 17 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 2014/10/03, 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 2014/10/03, 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 2014/10/03, 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. I do not hold and have not held and my employer SOIL ENGINEERS LTD. does not hold and has not held a direct or indirect interest in the RSC property or any property which includes the RSC property and was the subject of a phase one or two environmental site assessment or risk assessment upon which this record of site condition is based To the best of my knowledge, the certifications and statements in this part of the RSC are true as of 2014/10/03. By signing this RSC, I make no express or implied warranties or guarantees.

By checking the boxes above, and entering my membership/licence number in this submission, I, ELENI GIRMA BEYENE, a qualified person as defined in section 5 of O. Reg. 153/04 am, on 2015/01/20:

1.1.3 Subsurface Structures and Utilities

At the time of the initial investigation for the Phase Two ESA in 2012, the subject property contained four (4) multi-storey office buildings with basements. Underground utilities (gas, hydro, Bell, sewer and water) were also documented to be present at the subject property at that time.

Prior to the demolition of the previous buildings at the subject property, the exterior of the subject property (where contaminants found) was asphalt paved driveway and parking lot. This would have restricted the infiltration of the surface and rain water into contaminated fill.

Therefore, it is unlikely that the former substructures and underground utilities at the subject property would have affected contaminant distribution and transport with respect to the identified soil impact (which is impacted fill with PAHs and metals and inorganics) at the subject property.

During the bulk excavation for the proposed development, the soils (including impacted fill) were excavated and disposed off-site. The excavation for the proposed structure extended into shale bedrock, to an approximate founding depth of 12.0 m below ground surface (mbgs). Currently, no soil presents on the subject property.

At present, the subject property is under construction with a proposed high-rise condominium. A four-storey basement of the high-rise condominium is almost completed.

Phase Two Conceptual Site Model Reference No. 1310-E126 251 King Street East Page 9 of 17 City of Toronto

2.0 Physical Setting

2.1.1 Stratigraphy

The subject property is situated on Markham till plain where glacial drift predominates the soil stratigraphy. In places, the drift has been eroded by Peel Ponding and filled with lacustrine sand, silt, clay and reworked drift. Bedrock of Georgian Bay Formation lies below the drift and extends to a considerable depth in the area of the subject property.

At the time of the Terraprobe’s field investigation in 2012, three (3) boreholes were conducted to depths of 8.2 mbgs to 9.1 mbgs at the subject property. The subsoil condition at the borehole locations consisted of a layer of fill to depths of 0.76 mbgs to 1.5 mbgs followed by native deposits of sandy silt to silty sand and silty clay to silt.

During our site investigation in 2013, the subject property was excavated to the property boundary limits in all directions, except a small portion of soils at the west side. The soil profile of this remaining portion was similar with the description of the initial investigation by Terraprobe. Most of the soils (including the impacted fill) were removed from the subject property and disposed off-site. The excavation was extended to an average depth of 9.0 mbgs. Bedrock was exposed at the bottom of the excavation.

At the time of our recent field investigation for the Phase Two ESA Update, drilling was advanced at three (3) locations through the fillers of the shoring walls into the bedrock for groundwater monitoring and testing. Bedrock was encountered at depths of approximately 13.5 to 14.5 mbgs at the drilling locations. Monitoring wells were installed in each drilling location at depths ranging from approximately 17.0 to 18.0 mbgs, within the bedrock.

2.1.2 Site Hydrogeological Characteristics

The subject property is located in the larger hydrogeological region known as Southern Ontario Lowlands. It lies within the Don River Watershed. Groundwater flow directions within all aquifers in the Don River Watershed are southerly with ultimate discharge into Lake Ontario. Local flow deflections also occur near streams and associated valleys.

During the initial investigation for the Phase Two ESA by Terraprobe, each borehole was completed as monitoring well for groundwater monitoring and testing. The monitoring wells were installed at depths of 8.2 mbgs to 9.1 mbgs, within the silty clay to silt deposits. Based on the measured groundwater data of this investigation, the interpreted overburden groundwater flow direction is to the southwest and the horizontal hydraulic gradient for the investigated aquifer within the silty clay to silt at the subject property is 0.027m/m. The overburden groundwater contours and interpreted overburden groundwater flow direction are shown on Drawing No. CSM3A. Phase Two Conceptual Site Model Reference No. 1310-E126 251 King Street East Page 10 of 17 City of Toronto

During our 2014 investigation for the Phase Two ESA Update, a total of three (3) monitoring wells were installed within the shallow bedrock at depths ranging from approximately 17.0 to 18.0 mbgs for groundwater monitoring and testing. Based on the measured groundwater data of this investigation, the interpreted shallow bedrock groundwater flow direction is to the southwest and the horizontal hydraulic gradient for the investigated aquifer within the shallow bedrock at the subject property is 0.016m/m. The shallow bedrock groundwater contours and interpreted shallow bedrock groundwater flow direction are shown on Drawing No. CSM3B.

2.1.3 Approximate Depth to Bedrock

During our investigation in 2013, the subject property was excavated to the property boundary limits in all directions, except a small portion soils at the west side. The excavation was extended to an average depth of 9.0 mbgs. Bedrock was exposed at the bottom of the excavation.

During our recent investigation for the Phase Two ESA Update, bedrock was encountered at depths of approximately 13.5 to 14.5 mbgs at the drilling locations since the drilling was within the fillers of the shoring walls.

2.1.4 Approximate Depth to Water Table

Based on the groundwater records of the initial investigation in 2012 for Phase Two ESA, the depth to the shallow groundwater table within the overburden varies from approximately 2.8 mbgs to 8.1 mbgs.

Based on the groundwater records of the 2014 investigation for the Phase Two ESA Update, the depth to the groundwater table within the shallow bedrock varies from approximately 15.26 mbgs to 15.73 mbgs.

2.1.5 Section 41 or 43.1 of the Regulation Applies to the Property

The subject property is not within/adjacent/part of an area of natural significance and the review of analytical results indicated the soil at the property has pH value between 5 and 9 for surface soil and between 5 and 11 for subsurface soil. Therefore, Section 41 of the regulation (Site Condition Standards, Environmental Sensitive Areas) does not apply to the subject property.

The subject property is not a shallow soil property, as the bedrock was not encountered within 2 mbgs during the investigation. In addition, there is no water body located at the subject property and/or within a 30 m radius of the subject property. Therefore, Section 43.1 of the Regulation (Site Condition Standards, Shallow Soil Property or Water Body) does not apply to the subject property. Phase Two Conceptual Site Model Reference No. 1310-E126 251 King Street East Page 11 of 17 City of Toronto

2.1.6 Soils Placed On, In or Under the Phase Two Property

Based on the findings of the Phase One ESA, the subject property is located in an area of Toronto where poor quality fill soils are common.

The drilling investigation for the initial Phase Two ESA indicates a layer of soil fill was presented at depths of 0.76 mbgs to 1.5 mbgs in all three boreholes. In general, the fill consists of sand with some silty clay and trace gravel. At two of the borehole locations, the fill contains brick fragments and cinders. The encountered soil fill was assessed during the Phase Two ESA and was found to be impacted with PAHs and metals and inorganics. During the bulk excavation for the proposed development, the soils (including impacted fill) was excavated and disposed off-site with the excavation extending into the shale bedrock. No soils have been imported or placed on, in or under the subject property since the bulk excavation for the removal of soils from the subject property.

At present, the subject property is under construction with a proposed high-rise condominium. The excavation for the proposed structure extended into the shale bedrock, to an approximate founding depth of 12.0 mbgs.

2.1.7 Proposed Building and Other Structures

At present, the subject property is under construction with a proposed high-rise condominium occupying almost the entire area of the subject property. A four-storey basement of the high-rise condominium is almost completed.

3.0 Contamination In or Under the Phase Two Property

Based on the findings of the Phase One ESA, contaminants of potential concern in the soil and groundwater with respect to the identified APECs at the subject property were assessed.

Based on the information obtained from the Phase One ESA and Phase Two ESA, Table 3 Full Depth Generic Site Condition Standards in a Non-Potable Groundwater Condition for Residential/Parkland/ Institutional property use and for fine and medium textured soils as published in the “Soil, Ground Water and Sediment Standards for Use Under Part XV.1 of the Environmental Protection Act” (EPA), April 15, 2011 (Table 3 RPI Standards) was selected to be the applicable site condition standard for evaluating the soil and groundwater conditions at the subject property.

At present, the subject property is under construction with a proposed high-rise condominium. During the bulk excavation for the proposed development, the soils (including fill) was excavated and disposed off-site. The excavation for the proposed structure extended into the Phase Two Conceptual Site Model Reference No. 1310-E126 251 King Street East Page 12 of 17 City of Toronto

shale bedrock, to an approximate founding depth of 12.0 mbgs. There are no soils remaining at the subject property at the time of preparation of this Phase Two Conceptual Site Model.

The locations of the contaminants of concern, prior and during the bulk excavation, are shown on Drawing Nos. CSM4A and CSM4B. The locations of cross-sections are presented on Drawing Nos. CSM5A and CSM5B. Cross Sections through sampling locations (during the investigations in 2012, 2013 and 2014) are presented on Drawing Nos. CSM5C1, CSM5C2, CSM5D and CSM5E.

3.1.1 Area Where Contaminants are Present

The initial investigation for the Phase Two ESA by Terraprobe identified PAHs and metals and inorganics impacted fill above the Table 3 RPI Standards at the exterior of the former buildings at the subject property.

No contaminants are identified in the groundwater within the overburden or bedrock at a concentration above the Table 3 RPI Standards.

3.1.2 Contaminants Associated with Each Area

The contaminants found during the initial investigation for the Phase Two ESA consisted of the following parameters of PAHs and metals and Inorganics: Fluroanthene, Benz(a)anthracene, Chrysene, Benzo(b)fluoranthene, Benzo(k)fluoranthene, Benzo(a)pyrene, Indeno(1,2,3- cd)pyrene, Dibenz(a,h)anthracene, Electrical Conductivity, Lead, Mercury and Zinc.

3.1.3 Medium in which Each Contaminant were Found

Soil testing results from the initial investigation for the Phase Two ESA indicate that the historic soil fill at the subject property were found to exceed the Table 3 RPI Standards for some PAHs and metals and inorganics.

The fill consisted of sand with some silty clay and trace gravel. At two of the borehole locations, the fill contains brick fragment and cinders.

3.1.4 Description and Assessment of the Area Where Contaminant Found

During the initial investigation for the Phase Two ESA, selected soil samples from historical fill and native soils retrieved from the boreholes and groundwater samples from the monitoring wells conducted in the area where contaminants found (exterior of the previous buildings at the subject property) were analyzed for PHCs, VOCs, PAHs, PCBs, and/or metals and inorganics. Based on the review of the soil testing results of the initial investigation for the Phase Two ESA, Phase Two Conceptual Site Model Reference No. 1310-E126 251 King Street East Page 13 of 17 City of Toronto

the historic fill was found to contain contaminants of some parameters of PAHs and metals and inorganics in excess of the Table 3 RPI Standards. The impacted fill consisted of sand with some silty clay, trace gravel and occasional brick fragment and cinders, and extended to depths of 0.76 mbgs to 1.5 mbgs. Details of the soil (fill) exceedances are tabulated below:

Based on the review of the groundwater testing results of the initial investigation for the Phase Two ESA, no contaminants were identified in the groundwater within the overburden at a concentration above the applicable site condition standards (Table 3 RPI Standards).

During our site investigation in 2013 for Phase Two ESA Update, the subject property was excavated to the property boundary limits in all directions with shoring walls in place, except a small portion of soils near the west side of the subject property. The excavation was extended vertically to an average depth of 9.0 mbgs. Bedrock was exposed at the bottom of the excavation. One soil sample from the fill located within this remaining portion was collected and analyzed for PHCs, VOCs, PAHs, PCBs, metals and inorganics. No other confirmatory soil samples could be obtained from walls and floor of the excavation for chemical analyses, as shoring walls were in place in all directions and the exposed bedrock bottom of the excavation at the time of this investigation. Based on the review of the analytical results, the soil sample was found to meet the Table 3 RPI Standards.

Phase Two Conceptual Site Model Reference No. 1310-E126 251 King Street East Page 14 of 17 City of Toronto

During our 2014 investigation (a second stage investigation) for the Phase Two ESA Update, a total of three (3) monitoring wells were installed within the shallow bedrock at the subject property at depths ranging from 17.0 to 18.0 mbgs for groundwater monitoring and testing in order to meet the minimum requirements of the O. Reg. 153/04 as related to the impacted fill excavation at the subject property. Groundwater samples from each monitoring well were analysed for PHCs, VOCs, PAHs, PCBs, metals and/or inorganics. Based on the review of the groundwater testing results of the 2014 investigation, no contaminants are identified in the groundwater within the shallow bedrock at a concentration above the Table 3 RPI Standards. Consequently, the bedrock groundwater sample results confirmed that there are no contaminants of concern present at the subject property in excess of the Table 3 RPI Standards.

During the bulk excavation for the proposed development, approximately 5,200m3 of soils (including impacted fill) was excavated, removed and disposed off-site. The excavation for the proposed structure extended into the shale bedrock, to an approximate founding depth of 12.0 mbgs. There are no soils remaining at the subject property at the time of preparation of this Phase Two Conceptual Site Model.

Based on the findings of our Phase Two ESA Update, it is concluded that the previously identified soil impact with parameters of PAHs and metals and inorganics is successfully removed and no contaminants in excess of Table 3 RPI Standards are present at the subject property.

3.1.5 Distribution of Contaminants

Contaminants of some parameters of PAHs and metals and inorganics in excess of the Table 3 RPI Standards were identified in the historic fill at the exterior of the previous buildings at the subject property. The impacted fill extended to depths of 0.76 mbgs to 1.5 mbgs.

During the bulk excavation for the proposed development, all soils (including identified impacted fill) was excavated and disposed off-site. The excavation for the proposed structure extended into the shale bedrock, to an approximate founding depth of 12.0 mbgs. There are no soils remaining at the subject property at this time.

3.1.6 Reason for Discharge of Contaminants

The subject property is located in an area of Toronto where poor quality fill soils are common. The drilling investigation of the initial investigation in 2012 revealed that the fill at the borehole locations consisted of sand with some silty clay, trace gravel, brick fragments and cinders. Therefore, the presence of metals and PAHs impact at the subject property is most likely associated with the importation of poor quality fill soils to the subject property in the past.

Phase Two Conceptual Site Model Reference No. 1310-E126 251 King Street East Page 15 of 17 City of Toronto

3.1.7 Migration of Contaminants

Contaminants of PAHs and metals and inorganics in excess of the Table 3 RPI Standards were identified in the historic fill at the exterior of the previous buildings at the subject property. No contaminants in excess of the Table 3 RPI Standards were identified in the overburden and bedrock groundwater at the subject property. Consequently, no significant migration of contaminants is expected from the areas of potential environmental concern.

Furthermore, during the bulk excavation for the proposed development, all soils (including the impacted fill) was excavated and disposed off-site. The excavation for the proposed structure extended into the shale bedrock, to an approximate founding depth of 12.0 mbgs. There are no soils remaining at the subject property at this time.

3.1.8 Climatic or Meteorological Conditions Influencing Contaminant Distribution or Migration

Climatic or meteorological conditions are not anticipated to influence the distribution or migrations of contaminants, as no groundwater impacts were found at the subject property. Furthermore, the impacted historic fill at the subject property was found to be extended to depths ranged from 0.76 mbgs to 1.5 mbgs and the shallow overburden groundwater table at the subject property was found to be below 2.8 mbgs.

3.1.9 Soil Vapour Intrusion into Buildings

No soil vapour intrusion is anticipated at the subject property, as the previously identified impacted historic fill was related to the contaminants of some parameters of PAHs and metals and inorganics.

4.0 Potential Exposure Pathways and Receptors

The human and ecological receptor conceptual model is presented in Drawing No. CSM6.

4.1.1 Release Mechanisms

Contaminants of PAHs and metals and inorganics in excess of the Table 3 RPI Standards were identified in the historic fill at the exterior of the previous buildings on the subject property. The release of the identified contaminants was likely related to the importation of poor quality of fill soils to the subject property in the past.

Phase Two Conceptual Site Model Reference No. 1310-E126 251 King Street East Page 16 of 17 City of Toronto

4.1.2 Contaminant Transport Pathway

The contaminants of PAHs and metals and inorganics found at the subject property were in the fill near the surface. Generally, the contaminants in the near surface fill would have transported by infiltration and percolation.

Prior to the demolition of the previous buildings at the subject property, the exterior of the subject property where contaminants found was asphalt paved driveway and parking lots. This would have restricted the infiltration of the surface and rain water into contaminated fill. Therefore, no significant transport pathways of contaminants were identified at the subject property.

4.1.3 Receptors

Potential receptors located on, in or under the subject property are excavation workers on-site and organisms within the impacted fill.

Currently, all soils (including impacted fill) were excavated and removed off-site for disposal with foundations of the proposed structure extending into the shale bedrock. Consequently, there are no soils remaining at the subject property and no potential receptors are anticipated.

4.1.4 Receptor Exposure Points

Prior to the removal of the impacted fill, the receptor exposure points for the contaminants found at the subject property are soil based contamination.

Currently, all soils (including impacted fill) were excavated and removed off-site for disposal with foundations of the proposed structure extending into the shale bedrock. Consequently, there are no soils remaining at the subject property and no receptor exposure points are anticipated.

4.1.5 Routes of exposure

The routes of exposure for the identified soil impacts at the subject property would be dermal contact, ingestion and/or inhalation. Workers may have come into contact with soil during excavation and construction, but this is expected to be minimal as heavy equipment (excavator) was used to remove the soil from the subject property during bulk excavation for the proposed structures. In addition, construction/excavation workers usually use personal protective equipment (PPE) when handling soils. Therefore, the exposure to impacted soil is expected to be minimal.

Phase Two Conceptual Site Model Reference No. 1310-E126 251 King Street East Page 17 of 17 City of Toronto

Furthermore, the risk to ecological receptors is expected to be minimal, as no significant ecological habitat was identified at the subject property.

Currently, all soils (including impacted fill) were excavated and removed off-site for disposal with foundations of the proposed structure extending into the shale bedrock. Consequently, there are no soils remaining at the subject property and no routes of exposure are anticipated.
