23 February 1, 2013 File: A Delcan Corporation # Kingsway Burnaby, BC V5H 4M2 Attention: Mr. Colin Kristiansen Dear Mr. Kristiansen: WESTMINSTER HIGHWAY WIDENING, RICHMOND, BC ENVIRONMENTAL SOIL INVESTGATION Thurber Engineering Ltd. (TEL) was retained by Delcan Corporation (the Client ) to conduct an Environmental Investigation in conjunction with a geotechnical assessment on the proposed Westminster Highway expansion project in Richmond, BC. The expansion work is planned for the south side of Westminster Highway from McMillan Way to Nelson Road, and an approximately 250 m section on the west side of Nelson Road south of Westminster Highway (hereafter referred to as the Site ). The purpose of this investigation is to assess surficial roadside soils at the Site for potential contamination prior to organics stripping in preparation for highway widening and preload work. This report was prepared for the exclusive use of Delcan and the City of Richmond (CoR). Any use which a third party makes of this report, or any reliance on decisions based on it are the responsibility of such third parties. TEL accepts no responsibility for damage incurred by third parties as a result of decisions made or actions taken based on this report. Use of this report is subject to the attached Statement of Limitations and Conditions which are an integral part of this report. Thurber s scope of work comprised the following: Hand test pits at 32 locations across the Site. Collection of an environmental soil sample from each location. Laboratory testing of samples for Potential Contaminants of Concern (PCOCs). 1. REGULATORY FRAMEWORK Investigation and management of contaminated sites in British Columbia is governed by the BC Environmental Management Act (EMA) and the BC Contaminated Sites Regulation (CSR). Procedures and legal requirements for identifying, handling, treatment and disposal of hazardous wastes are described in the BC Hazardous Waste Regulation (HWR). The hazardous waste standards specified in the HWR apply to soil, surface water and groundwater at the Site. 900, 1281 West Georgia Street, Vancouver, BC V6E 3J7 T: F: thurber.ca

24 For a given substance in soil, the CSR provides either generic or matrix numerical standards. Generic standards are listed in Schedules 4 and 10 of the Regulation and are selected based only on the intended land use for the site. Matrix standards take into account site specific factors in addition to land use and the standard for a substance is determined by the lowest applicable concentration listed in Schedule 5 of the Regulation. The site specific standards account for human exposure by intake of contaminated soil and groundwater used for drinking water. Other factors include whether there is exposure to other environmental receptors such as soil invertebrates, livestock and aquatic life, and whether the water at the contaminated site will be used for irrigation. In terms of the site specific matrix standards within Schedule 5, the strictest of the following standards apply: Intake of contaminated soil. Toxicity to soil invertebrates. Groundwater flow to surface water used by aquatic life. Groundwater for potable water exposure pathway The commercial land use (CL) standards have been applied at the Site. In addition, the samples have been compared to the Soil Relocation (SR) standards in Schedule 7, as some of the material is to be transported outside Site boundaries. 2. FIELD METHODOLOGY The soil sampling was conducted on January 15, Sampling locations were approximately 50 m apart beginning at 25 m west of McMillan Way and ending at approximately 225 m south of Westminster Highway on Nelson Road. Sample locations were between 1 and 3 m from the edge of pavement, at the top edge of the roadside ditch. Hand test pits were advanced to a maximum depth of 0.45 m using a shovel. The soil samples were collected from beneath the topsoil layer, which varied between 3 and 45 cm in thickness. Where the topsoil was deeper than the maximum study depth of 0.45 m, the sample was collected from between 0.3 and 0.45 m below ground surface. Upon completion, the sampling locations were backfilled with the excavated soil and marked with a labelled stake. Soil samples were recovered by hand. Two jars were collected from each sample location. The samples were collected utilizing standardized sampling procedures, consistent with the BC Ministry of Environment s (MoE s) Contaminated Sites Regulations (CSR) Technical Guidance Document #1 Site Characterization and Confirmation Testing ANALYTICAL RESULTS A total of 32 soil samples and two duplicates were collected and analyzed for one or more of the PCOCs. Selected soil samples were submitted to AGAT Laboratories of Burnaby, BC (AGAT) 1 Province of British Columbia. Ministry of Environment (1997). Technical Guidance: Site Characterization and Confirmation Testing [Guidance Document #1]. Victoria: MoE.

25 for analysis of Light/Heavy Extractable Petroleum Hydrocarbons (LEPH/HEPH), and Polycyclic Aromatic Hydrocarbons (PAH), and all samples and duplicates were submitted for analyses of BC CSR Metals and soluble sodium and chloride. The analytical results are included in Tables 1 and 2 at the end of this report. Due to differing construction schedules, the results for the investigation will be discussed in two sections corresponding to the construction phases. Phase I consists of the area starting approximately 370 m east of Nelson Road and ending at McMillan Way; sample locations for Phase I are depicted on the Delcan drawings labelled Oc Phase II consists of the remaining section of Westminster Highway between Phase I and Nelson Road, as well as an approximately 250 m section of Nelson Road extending south from Westminster Highway; sample locations for Phase II are depicted on the Delcan drawing labelled Oc Phase I Sample Results A total of 20 sample locations were included in Phase I. All samples analyzed for LEPH/HEPH and PAH contained concentrations below the applicable standards. The following sample exceedances were noted: 10 samples had zinc concentrations above the SR standard 1 sample had a copper concentration above the SR standard 3 samples had chloride concentrations above the SR standard No samples had any PCOC concentrations above the CL standards. 3.2 Phase II Sample Results A total of 12 sample locations were included in Phase II; 7 samples were located along Westminster Highway and 5 samples were located along Nelson Road. All samples analyzed for LEPH/HEPH and PAH contained concentrations below the applicable standards. The following sample exceedances were noted: 7 samples had zinc concentrations above the SR standard 5 samples had sodium concentrations above the SR standard 1 sample had a chloride concentration above the SR standard 4 samples had copper concentrations above the SR standard 7 samples had chloride concentrations above the CL standard 3 samples had zinc concentrations above the CL standard All sample locations along Nelson Road had CL exceedances of either chloride or zinc. Two locations along Westminster Highway had CL exceedances of chloride. Analytical certificates are attached.

26 4. QUALITY ASSURANCE AND QUALITY CONTROL (QA/QC) 4.1 Field QA/QC Activities The following points summarize the Quality Assurance and Quality Control (QA/QC) measures employed for the investigation field work: All field personnel were properly trained to conduct the investigation work. All instrumentation was cleaned and calibrated on a regular basis by trained TEL equipment technicians. Instrumentation is periodically calibrated in the field if conditions dictate. All instrumentation was operated according to the manufacturer s instructions. Nitrile gloves were worn by field personnel and changed between sample intervals and locations to minimize potential for cross-contamination of samples. Soil samples were placed in clean, laboratory-provided 125 ml glass jars with Teflon -lined lids containers and placed in a cooler with ice packs prior to being submitted to a Canadian Association for Laboratory Accreditation (CALA) accredited analytical laboratory. Chain of custody forms were completed and accompanied all submitted samples to the laboratory. Approximately 1 blind field duplicate sample was obtained for a minimum of every 10 samples collected during the field investigation. 4.2 Internal QA/QC Select samples were submitted to AGAT for quantitative analysis, these results were used to calculate the relative percent difference (RPD) between the sample and the blind duplicate using the following formula: RPD = 2 ABS [(X-Y)/(X+Y)] Where: ABS = Absolute value X = Concentration of original sample Y = Concentration of blind duplicate sample Where the concentration of a given parameter was less than 5 times the analytical method detection limit (MDL), the results are less precise and a RPD was not calculated but the difference factor (DF) was calculated, which is the absolute difference between the two sample concentrations. Any RPD value greater than 30% is deemed unacceptable by QA/QC standards. High RPD values require further investigation into the cause for these discrepancies. Inquiries are made to the analytical laboratory and field staff regarding batch quality control, reporting errors, sampling methods and inherent field errors in order to explain why the discrepancy occurred. Samples SS13-05 and SS13-29 and their duplicates labeled SS13-A and SS13-C, respectively, were analyzed for QA/QC. Several calculated RPD values were greater than 30% for these Client: Delcan Corporation February 1, 2013 File No.: A E-File: a_jmg_rpt_enviro memo_ a rev1 Page 4 of 7

27 duplicates; however, both duplicates had an average RPD that is below 30%. In addition, the RPDs for analyses of zinc and copper, concentrations of which exceeded the applicable standards in several samples, were below 30% for both duplicates. RPDs for soluble sodium and chloride were below 30% in one duplicate, but above 30% in the other. However, concentrations of soluble sodium and chloride in the duplicate with an RPD of greater than 30% were still below applicable standards. Given that no concerns were raised by the laboratory regarding this sample s integrity, TEL believes the difference to have been caused by heterogeneity in the sample. 4.3 Laboratory QA/QC AGAT is a CALA accredited laboratory. As such, proper laboratory QA/QC methods are required as follows: The chemical laboratory used must have achieved proficiency certification by CALA for the analyses performed. In addition to the field samples and blind field duplicates, each batch should include at least one laboratory duplicate sample, one analytical blank, and one reference sample (a certified reference standard, spike or control standard). Reported concentrations should not exceed the instrument calibration range. Analytical blanks should be below the detection limits used for the specific analysis. Laboratory duplicates should fall within the Data Quality Objectives set by the laboratory. Analytical results for all reference materials or spiked standards should be within the target specified by the laboratory. In addition, AGAT includes at least one analytical blank and one laboratory duplicate sample, as required by their data quality objectives. Reports from the lab are internally reviewed by TEL and if any laboratory QA/QC problems are encountered, the field samples and internal QA/QC samples are re-analyzed. No QA/QC issues were identified. Given this, we have confidence that the analytical data is valid. Laboratory QA/QC results are presented in the laboratory certificate in Appendix C. 5. FINDINGS AND RECOMMENDATIONS 5.1 Phase I All soil samples obtained from the Phase I work area had concentrations below the CL standards, therefore the soil within this area is not considered contaminated as defined by the CSR. Approximately half of the sample locations had exceedances of the SR standards, which affects how the soil may be moved off-site. Client: Delcan Corporation February 1, 2013 File No.: A E-File: a_jmg_rpt_enviro memo_ a rev1 Page 5 of 7

28 The work area is within a City of Richmond right-of-way; therefore as long as the soil remains within this right-of-way it will not require a Soil Relocation Agreement (SRA). If Delcan/CoR plans to move the soil outside the right-of-way to a location that is not a licensed treatment facility, an SRA will be required. The soil may be disposed of at a licensed treatment facility without an SRA. 5.2 Phase II Multiple CL exceedances were observed within the Phase II work area, consisting of zinc and chloride contamination. It is TEL s opinion that these exceedances are consistent with general road activities such as salting, vehicle exhaust emissions, and/or vehicle accidents. Given that all samples along Nelson Road had CL exceedances, TEL recommends that any soil excavated/stripped within this area be disposed of at a licensed treatment facility. This would be considered remediation under the CSR and Delcan/CoR would be obligated to complete a Notification of Independent Remediation and submit it to MoE. Typically, this would also involve confirmatory sampling to confirm that the remediation was completed satisfactorily. However, given that the road will continue to be used following construction and that additional deposits of these materials are likely to occur, full completion of remediation would seem illogical at this time. TEL recommends that the CoR be consulted as to whether they would require the remediation process to MoE standard. Consideration could also be given to approaching MoE for an exemption from having to consider these deposits as contamination. A similar approach was used by the Ministry of Transportation during the Port Mann Highway 1 upgrade project to deal with roadside contamination along the highway corridor. However, this did not exempt the requirement for proper disposal if any impacted materials were moved outside the highway right-of-way. If this option is of interest to Delcan/CoR, TEL will endeavour to obtain a copy of the memorandum from the relevant parties. Two of the seven locations along Westminster Highway had CL exceedances. If Delcan/CoR intends to re-use any stripping within this area along the right-of-way, additional sampling will be necessary to confirm the extent of contamination. Alternatively, the stripping from this section of Westminster Highway could be disposed of at a licensed treatment facility without an SRA.

INTERPRETATION OF THE REPORT a) b) Nature and Exactness of Soil and Contaminant Description: Classification and identification of soils, rocks, geological units, contaminant materials and quantities have been based on investigations performed in accordance with the standards set out in Paragraph 1. Classification and identification of these factors are judgmental in nature. Comprehensive sampling and testing programs implemented with the appropriate equipment by experienced personnel, may fail to locate some conditions. All investigations utilizing the standards of Paragraph 1 will involve an inherent risk that some conditions will not be detected and all documents or records summarizing such investigations will be based on assumptions of what exists between the actual points sampled. Actual conditions may vary significantly between the points investigated and the Client and all other persons making use of such documents or records with our express written consent should be aware of this risk and this report is delivered on the express condition that such risk is accepted by the Client and such other persons. Some conditions are subject to change over time and those making use of the Report should be aware of this possibility and understand that the Report only presents the conditions at the sampled points at the time of sampling. Where special concerns exist, or the Client has special considerations or requirements, the Client should disclose them so that additional or special investigations may be undertaken which would not otherwise be within the scope of investigations made for the purposes of the Report. Reliance on Provided Information: The evaluation and conclusions contained in the Report have been prepared on the basis of conditions in evidence at the time of site inspections and on the basis of information provided to us. We have relied in good faith upon representations, information and instructions provided by the Client and others concerning the site. Accordingly, we cannot accept responsibility for any deficiency, misstatement or inaccuracy contained in the Report as a result of misstatements, omissions, misrepresentations, or fraudulent acts of the Client or other persons providing information relied on by us. We are entitled to rely on such representations, information and instructions and are not required to carry out investigations to determine the truth or accuracy of such representations, information and instructions.
