EXECUTIVE SUMMARY

Pinchin Environmental Ltd. (“Pinchin”) was retained by Shad & Associates Inc. (“Shad”) on behalf of Royal Park Homes (“Client”) to conduct a Phase II Environmental Site Assessment (“ESA”) of the property located at 31 and 33 Milton Heights Crescent and 149 Tremaine Road, Milton, Ontario (hereafter referred to as the “Site”). The Site was developed with three (3) residential dwellings, a shed and a commercial building occupied by a trucking operation and offices (“Site Buildings”).

The Phase II ESA was conducted by Pinchin at the request of Shad in relation to the potential acquisition and future redevelopment of the Site.

Based on the work completed, the following is a summary of the activities and findings of this Phase II ESA:

1. Pinchin supervised the Client-retained drilling contractor (Strong Soil Search Inc.) to advance eight (8) boreholes on August 8, 2011. The boreholes were advanced to a maximum depth of 6.10 metres below ground surface (“mbgs”). Five (5) of the eight (8) boreholes were instrumented with monitoring wells to enable groundwater monitoring and sampling. The boreholes were advanced using a CME 55 truck mounted drill rig;

2. The soil stratigraphy at the Site generally consisted of fill material (sand and gravel) throughout the Site to a maximum depth of 0.76 mbgs. Native subsurface material underlying the fill material was observed to generally consisted of clay with some silt and trace sand overlying silt with some sand and trace clay. Moist to wet soil conditions were generally observed at a maximum depth of approximately 4.1 mbgs;

3. Groundwater levels at the Site varied between 0.83 mbgs (BH314) and 2.08 mbgs (BH316). Inferred groundwater flow direction is expected to be towards the southeast based on topography and the presence of Sixteen Mile Creek located southeast of the Site;

4. Based on the Site specific information, the soil and groundwater quality was assessed based on the Table 2 Full Depth Generic Site Condition Standards in a Potable Groundwater Condition, for residential/parkland/institutional land use and medium and fine grained soils. These guidelines are outlined in the “Soil, Groundwater and Sediment Standards for Use Under Part XV.1 of the Environmental Protection Act”, Ontario Ministry of the Environment (“MOE”), April 15, 2011, and hereinafter referred to as the “Table 2 Standards”;

5. Five (5) “worst case” soil samples were selected for chemical analysis from the borehole locations for petroleum hydrocarbons (“PHCs”) fractions 1 to 4 (F1-F4), volatile organic compounds (“VOCs”) and metals;

6. Three (3) soil samples were selected for chemical analysis from the remaining shallow borehole locations for chemical analysis of metals;

7. Two (2) soil samples were submitted for laboratory analysis of pH and one (1) soil sample for a grain size analysis.

8. Groundwater samples were collected on August 10, 2011, from monitoring wells BH312, BH314, BH316, BH317 and BH317. The groundwater samples were submitted for chemical analysis of PHC (F1-F4) and VOC parameters;

9. All measured concentrations in soil samples submitted for analysis satisfied the Table 2 Standards; and

10. All measured concentrations satisfied the Table 2 Standards in the groundwater samples analyzed.

Based on the findings of this Phase II ESA, it is Pinchin’s opinion that no further subsurface investigation is required at the Site in relation to the findings of the Phase I ESA.

This Executive Summary is subject to the same standard limitations as contained in the report and must be read in conjunction with the entire report.

1.0 Introduction

Pinchin Environmental Ltd. (“Pinchin”) was retained by Shad & Associates Inc. (“Shad”) on behalf of Royal Park Homes (“Client”) to conduct a Phase II Environmental Site Assessment (“ESA”) of the property located at 31 and 33 Milton Heights Crescent and 149 Tremaine Road, Milton, Ontario (hereafter referred to as the “Site”). The Site was developed with three (3) residential dwellings, a shed and a commercial building occupied by a trucking operation and offices (“Site Buildings”). The Site location is identified in Figure 1 of Appendix I.

The Phase II ESA was conducted by Pinchin at the request of Shad in relation to the potential acquisition and future redevelopment of the Site.

1.1 Scope of Work

All work completed under this project will be performed in general accordance with standard engineering practices and the following documents:

Ontario Ministry of the Environment (“MOE”) document entitled “Guidance on Sampling and Analytical Methods for Use at Contaminated Sites in Ontario”, revised February 1997 (“MOE Sampling Guideline”);

Ontario Regulation 153/04 “Record of Site Condition” dated October 2004; and

Canadian Standards Association (“CSA”) publication entitled “Phase II Environmental Site Assessment, CSA Standard Z769-00 (reaffirmed 2004)”.

The scope of work for this Phase II ESA was outlined in the Pinchin proposal to Client dated July 26, 2011 and consisted of the following:

Advanced five (5) deep boreholes to a maximum depth of 6.1 metres below ground surface (“mbgs”) and three (3) shallow boreholes to a maximum depth of 5.2 mbgs. Each of the five (5) deep boreholes were completed as groundwater monitoring wells;

Field screened soil samples for the presence of petroleum/solvent-derived vapours using visual and olfactory considerations, along with a hydrocarbon vapour surveyor (“Gastech”) calibrated to hexane, and a photo-ionization detector (“PID”) calibrated to isobutylene;

Obtained one most-apparent “worst case” soil sample, based on the field screening methodologies, from each of the five (5) deep boreholes for chemical analysis of petroleum hydrocarbons (“PHCs”) fractions 1 through 4 (“F1-F4”), volatile organic compounds (“VOCs”) and metals. One soil sample was obtained from each of the three (3) shallow boreholes for chemical analysis of metals;

Submitted one representative soil sample for grain size analysis and two (2) soil samples for laboratory analysis of pH in order to confirm the appropriate standards identified in the MOE document entitled “Soil, Ground Water and Sediment Standards for Use under Part XV.1 of the Environmental Protection Act” dated April 15, 2011 (“2011 MOE Standards”);



Conducted groundwater monitoring within the newly installed monitoring wells. Groundwater samples were collected from the monitoring wells and submitted for laboratory analysis of PHCs and VOCs;

Evaluated the results of the soil and groundwater analyses by comparing the analytical results to the applicable 2011 MOE Standards; and

Prepared a factual report (this report) detailing the findings of the Phase II ESA and recommendations.

2.0 Methodology

2.1 Borehole Investigation

The investigation methodology was conducted in general accordance with the MOE Sampling Guideline and Ontario Regulation 153/04.

The Client retained Strong Soil Search Inc. to conduct the drilling activities at the Site. Pinchin supervised Strong Soil Search Inc. to advance eight (8) boreholes on August 8, 2011. Five (5) of the eight (8) boreholes were instrumented with monitoring wells to enable groundwater monitoring and sampling. The boreholes were advanced to depths ranging from 5.0 mbgs to 6.10 mbgs using a CME 55 truck mounted drill rig system.

Soil samples were collected at semi-continuous intervals using stainless steel split spoons. Discrete soil samples were collected from the split spoons and containerized in laboratory-supplied glass sampling jars. Subsurface soil conditions were logged on-Site by Pinchin personnel at the time of drilling. Soil samples were visually classified and were analyzed in the field for hydrocarbon derived vapour concentrations using the Gastech and PID.

The locations of the boreholes/monitoring wells are shown on Figure 2. A description of the subsurface stratigraphy encountered during the drilling program is documented in the borehole logs included in Appendix II.

2.2 Monitoring Well Installation

Groundwater monitoring wells were installed in boreholes BH312, BH314, BH316, BH317 and BH318 to enable groundwater monitoring and sampling.

The monitoring wells were constructed with 52 mm (2.0 inch) inner diameter (“ID”) flush-threaded schedule 40 PVC risers followed by a length of No. 10 slot PVC screen that attempted to traverse the water table. The screens were sealed using threaded caps and the riser was sealed at the surface with a lockable J-Plug cap. Silica sand was placed around and above the screened interval to form a filter pack around the well screen. A layer of bentonite was placed above the silica sand and was extended to ground surface. A protective steel above-grade casing was installed over the riser pipe and concreted in place at BH314, BH317 and BH318. No protective casings were available on Site to install at BH312 and BH316.



2.3 Groundwater Monitoring and Development Program

On August 9, 2011, the groundwater monitoring wells were gauged for groundwater levels and the presence of non-aqueous phase liquids (“NAPL”) using a Solinst 121 Interface probe. The probe was cleaned with a solution of Alconox detergent and potable water prior to and after each measurement. The measured depths to groundwater are provided in Table 1.

Groundwater development was accomplished by utilizing a dedicated inertial pump (bailer) for each monitoring well to draw the groundwater sample(s) to the surface.

2.4 Sampling and Laboratory Analysis

2.4.1 Soil

Soil samples collected from the boreholes were field screened for hydrocarbon-derived vapour concentrations using the Gastech and PID. Organic vapour concentrations measured in the soil samples during the drilling investigation are presented on the borehole logs in Appendix II. One (1) most apparent “worst case” soil sample based on vapour concentrations, visual, and olfactory considerations was recovered from each of the boreholes and placed into laboratory-prepared sample bottles, and stored in coolers with ice. Selected samples were submitted to Maxxam Analytics Inc. (“Maxxam”) in Mississauga for laboratory analysis of metals, PHCs F1-F4, VOCs and metals. Formal chain of custody records were maintained between Pinchin and the staff at Maxxam.

A summary of the soil samples collected and submitted for laboratory analyses is presented in Table 2.

2.4.2 Groundwater

On August 10, 2011, groundwater samples were collected from the newly-installed groundwater monitoring wells. Prior to collection of groundwater samples, the monitoring wells were purged of three (3) to five (5) well casing volumes or till they went dry, in accordance with Pinchin’s standard field practices. The groundwater samples were placed into laboratory-prepared sample bottles and stored in coolers with ice. Groundwater samples were submitted to Maxxam for laboratory analysis of PHCs and VOCs. Formal chain of custody records were maintained between Pinchin and the staff at Maxxam.

A summary of the groundwater samples collected and submitted for laboratory analyses is presented in Table 2.

2.5 Quality Assurance/Quality Control Protocols

Quality assurance/quality control (“QA/QC”) protocols were followed during the field program to ensure that representative samples were obtained. Field QA/QC protocols that were employed include:



Extraction of soil samples from the interior of the sampling device (where possible), rather than from areas in contact with the sampler walls to minimize the chance of cross-contamination. Split spoon sampling devices were cleaned with Alconox and potable water between sample collection;

Prior to collecting groundwater samples, the well was developed by purging three (3) to five (5) well casing volumes or till the borehole went dry. Upon completion of developing/purging activities, the wells were allowed sufficient time to recover prior to sampling;

Soil and groundwater samples collected were placed in laboratory-supplied glass sample jars;

Placement of all samples on ice immediately upon collection and appropriate temperatures maintained en route to the laboratory;

Use of dedicated and disposable nitrile gloves for all sample handling;

Sample collection and handling procedures were performed in general accordance with the MOE Sampling Guideline; and

Laboratory QA/QC consisted of lot replicate samples, surrogate recoveries and matrix blanks.

2.6 Ontario Water Well Records

The Ontario Water Resources Act, Ontario Regulation 903 (O.Reg. 903/128) requires all test holes greater than 3.0 mbgs have a water well record completed by a licensed well technician. The owner of the monitoring well must keep the water well record on file for a period of two years and the monitoring wells must be decommissioned as per O.Reg. 903/128 if monitoring wells are no longer in use. Strong Soil Search Inc. is a licensed well driller under O.Reg. 903/128.

2.7 Site Condition Standards

This Site is a residential/commercial property located within the Town of Milton. It is Pinchin’s understanding that drinking water for the Site and surrounding area is supplied by municipal services, with Lake Ontario and private wells serving as the water source. Native subsurface material underlying the fill material was observed to generally consist of sand and clay with some silt and trace sand overlying silt with some sand and trace clay to a maximum depth of 6.10 mbgs.

Two (2) representative soil samples were collected from the boreholes advanced at the Site and submitted for pH analysis. The MOE Standards indicate that a Site is classified as sensitive if the pH values of the surface soil (less than 1.5 mbgs) are less than 5 or greater than 9, and subsurface soils (greater than 1.5 mbgs) are less than 5 or greater than 11. Based on the analytical results, pH values of the subsurface soil do not indicate that the property is a “sensitive site”.



One (1) representative soil sample was collected from a borehole advanced at the Site and submitted for 75 µm single-sieve grain size analysis. Based on the results of the analysis, the soil at the Site can be considered as fine textured for the purposes of the MOE Standards.

Therefore, based on the above information (as presented in Table 3), the appropriate Site Condition Standard is:

“Soil, Ground Water and Sediment Standards for Use Under part XV.1 of the Environmental Protection Act” - “Table 2: Full Depth Generic Site Condition Standards in a Potable Ground Water Condition”, dated April 15, 2011 (“Table 2 Standards”) for:

Fine-medium textured soils; and

Residential/Parkland/Institutional property use.

As such, all analytical results have been compared to these Table 2 Standards.

3.0 Results

3.1 Site Geology and Hydrogeology

Data collected during the borehole drilling program indicated that the soil stratigraphy at the Site was observed to generally consist of fill material (sand, sand and gravel) throughout the Site to depths ranging between 0.15 mbgs (BH316) and 0.76 mbgs (BH311, BH312, BH313, BH315 and BH317). The fill material was observed to overlay native soil of clay with some silt and trace sand overlying silt with some sand and trace clay to a maximum depth of 6.10 mbgs. A description of the subsurface stratigraphy encountered during borehole advancement is documented in the borehole logs.

Groundwater monitoring was conducted on August 9, 2011. No NAPL was detected in any of the wells at the time of monitoring.

The depth to groundwater measured within the monitoring wells ranged from 0.83 mbgs (BH314) and 2.08 mbgs (BH316).

The groundwater measurement data is presented in Table 1.

3.2 Subsurface Conditions and Vapour Concentrations

Soil vapour headspace concentrations measured in the soil samples collected during the verification soil sampling program are presented in the borehole logs in Appendix II. As noted, soil vapour headspace readings obtained from the Gastech ranged from 0 parts per million (“ppm”) to 15 ppm (BH315 between 4.57 and 5.03 mbgs). Soil vapour headspace readings from the PID ranged from 0 ppm to 2.5 ppm (BH317 between 1.52 and 2.13 mbgs also at BH318 between 4.57 and 5.18 mbgs).

No staining and/or odours were observed in soil samples collected during the investigation.



3.3 Analytical

3.3.1 Soil

The summary of the soil analytical results of PHCs, VOCs and metals, along with the applicable Table 2 Standards are presented in Table 4 through Table 6.

As indicated in Table 4 through Table 6, all measured concentrations of PHCs, VOCs and metals in the collected soil samples were below the Table 2 Standards.

3.3.2 Groundwater

The summary of the groundwater analytical results of PHCs and VOCs, along with the applicable Table 2 Standards are presented in Table 7 and Table 8.

As indicated in Table 7 and Table 8, all measured concentrations of PHCs and VOCs in the groundwater samples were below the Table 2 Standards.

4.0 Findings and Conclusions

Based on the work completed as part of this Phase II ESA, the following conclusions are made:

Pinchin supervised the Client-retained drilling contractor (Strong Soil Search Inc.) to drill eight (8) boreholes. The boreholes were advanced to a maximum depth of 6.10 mbgs;

The soil stratigraphy at the Site generally consists of sand, sand and gravel to a maximum depth of 0.76 mbgs overlying clay with some silt and trace sand and generally followed by silt with some sand and trace clay to a maximum depth of 6.10 mbgs.

Groundwater monitoring was conducted on August 9, 2011 in the five (5) boreholes completed as monitoring wells. The depth to groundwater measured within monitoring wells ranged between 0.83 mbgs and 2.08 mbgs;

It was determined that the applicable Site Condition Standard for the Site is are the Table 2 Standards for:

o Fine to medium textured soils; and

o Residential/Parkland/Institutional property use.

All measured concentrations of PHCs, VOCs and metals in the soil samples collected were below the Table 2 Standards; and

All measured concentrations of PHCs and VOCs in the groundwater samples were below the Table 2 Standards.

Based on the findings of this Phase II ESA, it is Pinchin’s opinion that no further subsurface investigation is required at the Site.



5.0 Disclaimer

This Phase II ESA was performed for Royal Park Homes in order to investigate potential environmental impacts at the Site. The term recognized environmental condition means the presence or likely presence of any hazardous substance on a property under conditions that indicate an existing release, past release, or a material threat of a release of a hazardous substance into structures on the property or into the ground, groundwater, or surface water of the property. This Phase II ESA does not quantify the extent of the current and/or recognized environmental condition or the cost of any remediation.

Conclusions derived are specific to the immediate area of study and cannot be extrapolated extensively away from sample locations. Samples have been analyzed for a limited number of contaminants that are expected to be present at the Site, and the absence of information relating to a specific contaminant does not indicate that it is not present.

No environmental site assessment can wholly eliminate uncertainty regarding the potential for recognized environmental conditions on the property. Performance of this Phase II ESA to the standards established by Pinchin is intended to reduce, but not eliminate, uncertainty regarding the potential for recognized environmental conditions on the property, and recognizes reasonable limits on time and cost.

This Phase II ESA was performed in general accordance with currently acceptable practices for environmental site investigations, specific Client requests, and the project budget, as applicable to this property.

Pinchin will not be responsible for any consequential or indirect damages. Pinchin will only be held liable for damages resulting from negligence of Pinchin. Pinchin will not be liable for any losses or damage if Client has failed, within a period of two (2) years following the date upon which the claim is discovered within the meaning of the Limitations Act, 2002 (Ontario), to commence legal proceedings against Pinchin to recover such losses or damage.

Pinchin makes no other representations whatsoever, including those concerning the legal significance of its findings, or as to other legal matters touched on in this report, including, but not limited to, ownership of any property, or the application of any law to the facts set forth herein. With respect to regulatory compliance issues, regulatory statutes are subject to interpretation and these interpretations may change over time.

Any use of this report by another party other than the Client, or any reliance on or decisions made based on the findings described in this report, are the sole responsibility of such parties, and Pinchin accepts no responsibility for damages, suffered by any such party as a result of decisions made or actions conducted based on this report. No other warranties are implied or expressed. Furthermore, this report should not be construed as legal advice.
