Part 3. Site investigation status

Section V. Onsite and offsite investigation status

A. Adequacy of completed site investigations

Is site information appropriate and satisfactory to determine a site risk classification? yes no

If no, indicate the scheduled completion date of investigations needed to complete classification below.

B. Onsite investigation status Scheduled Completion Date

1. Stage I preliminary site investigation completed? yes no

2. Stage II preliminary site investigation completed? yes no

3. Detailed site investigations completed? yes no

4. Offsite migration of contamination identified? yes no

C. Offsite investigation status

1. Stage I preliminary site investigation completed? yes no N/A

2. Stage II preliminary site investigation completed? yes no August 9, 2010

3. Detailed site investigations completed? yes no September 30, 2010

Section VI. Onsite high risk conditions details

1. Is mobile NAPL present onsite? yes no

If yes, describe the mobile NAPL substances and their general location.

Laboratory analysis of NAPL samples taken from offsite seeps and on-site wells are interpreted to include straight-run gasoline, diesel and traces of crude oil. NAPL was noted in May 2010 to be present in five extraction wells (UEIB-1,UEIB-2, UEIB-3, UEIB-5 and UEIB-6) and one monitoring well (A2MW09-01). NAPL was measured in UEIB-2,UEIB-6 and A2MW09-1 with an apparent thickness greater than 0.3 metres. Taken on their own, three above mentioned wells encompass an area greater than 50m2. Therefore, according to protocol 16 and the above lines of evidence, mobile NAPL is present on-site.

4

2. Area upper cap concentrations exceeded? yes no

If yes, what substances exceed upper cap concentrations, in what media?

Volatile petroleum hydrocarbons (VHw(C6-C10)) were reported to be present in groundwater at concentrations of 30700 µg/L which exceed the UC concentration limit of 30,000 µg/L for marine aquatic life. Naphthalene was reported to be present in groundwater at concentrations of 113 µg/L which exceed the UC concentration limit of 100 µg/L for marine aquatic life.

3. Exposure pathways – are the risk criteria for any exposure pathway exceeded? yes no

If yes, which exposure pathways indicate high risk? Attach Exposure Pathway Questionnaire.

The site qualifies as a high risk site due to the presence of mobile NAPL. Assessment of on-site exposure pathways has not been completed.

Section VII. Onsite site risk classification

high risk not high risk

Note that for sites for which there is insufficient information to determine the site risk classification, information on the scheduled dates for completion of site investigations must be provided in Part 2 of this report.

Part 4. Independent remediation status

Section VIII. Onsite independent remediation

Has independent remediation been initiated at the site? yes no

Will the independent remediation of high risk conditions be completed within 90 days? yes no

If independent remediation of high risk site conditions is being carried out and is not completed within 90 days the Director must be provided a revised site classification report and an updated completion of remediation schedule at the 90th day of independent remediation.

Part 5. Offsite conditions

Section IX. Offsite high risk conditions details

1. Is mobile NAPL present or likely present offsite? yes likely no

If yes or likely, describe the mobile NAPL substances and their general location.

NAPL is present in a ditch running along the south side of a railway line on the neighboring property to the north owned by Canadian Pacific Railway (CP). The NAPL has been described as black and seeping out of the southern slope above the ditch. NAPL is also present in the foreshore area to the north of the CP land and is seeping from the rocks at the base of the slope above the high water mark.

5

2. Are upper cap concentrations exceeded or likely exceeded offsite? yes likely no

If yes or likely, what substances exceed or are likely to exceed upper cap concentrations, and in what media?

Volatile petroleum hydrocarbons (with the exception of benzene, toluene, ethylbenzene, and xylenes) (VPHs) were reported to be present in soil at concentrations of 7100 µg/g which exceeds the upper cap (UC) concentration limit of 2,000 µg/g for industrial land use. Considering the presence of NAPL on CP land and on the foreshore and the concentrations upgradient, it is likely that VHw(C6-C10) and Napthalene exceed the UC concentration limit in water and it is possible that Napthalene and total PAHs exceed the UC concentration limits in sediment.

3. Are high risk exposure pathways present or likely present offsite? yes likely no

If yes or likely, list the exposure pathways which impact or are likely to impact offsite receptors. Attach Exposure Pathway Questionnaire.

The off-site exposure pathway questionnaire will be completed once a preliminary and detailed site investigation (PSI and DSI) are completed.

4. Are any offsite parcels classified as high risk or likely classified as high risk? yes no

If yes, list the following for each offsite parcel

Site ID (if known) Offsite parcel owner Civic Address

6

Part 6. Signatures

Section X. Professional signatures

I confirm that the investigations referred to above have been conducted in accordance with approved procedures and guidance and standard professional practice. I confirm the above information and that provided on the Exposure Pathway Questionnaire, if attached, to be true, based on current knowledge as of the date completed.

Chevron Refinery Seep, Interpreted analytical chemistry results for the wells and seeps. MoE File 6726. Further to the Ministry of Environment (MoE) letter dated June 8, 2010, the following is in response to request #9 “Interpreted analytical chemistry results for the wells and seeps”. Three hydrocarbon samples were taken at different times and analyzed. The results are attached and summarized below.

• A site air photo showing the locations of the samples is attached. The Ditch and Beach samples are seep samples; MW09-01 was recovered from a monitoring well.

• The three samples MW09-01, Ditch, and Beach appear similar, except weathered to a different extent.

• The sample from well MW09-01 is the least weathered. It is comprised of approximately 25% diesel & the balance is heavier straight-run gasoline. There is a possibility for very small amounts of jet fuel and crude oil.

• The metals analysis (Maxxam reports ND on both nickel (Ni) & vanadium (V)) would suggest that this material is not straight crude oil as crude oil would contain appreciable amounts of these heavy metals. These data indicate that metals are not contaminants of concern.

• The total sulfur content of 0.11 wt% of the MW09-01 sample suggests that this material has not been hydrotreated (hydrotreating reduces sulfur content in diesel to ~ 0.001 wt% or 10 ppm).

Laboratory test results files are attached for the: Beach sample

• Maxxam – Contaminated Sites Regulation (CSR) parameters, EPH chromatogram, and metals

• In-house analytical Ditch sample

• Maxxam – CSR parameters, EPH chromatogram, and metals • In-house analytical

MW09-01 sample

• Maxxam – CSR parameters, EPH chromatogram, and metals • In-house analytical in two files

1.02 0.061Liquid pumped into a 210 litre drum over a measured period of time. 2Depth to water and NAPL (if present) in drum which is ~88cm deep.3Extracted volume calculated as: 210 litres - 2.4cm2*Depth to liquid.4 Calculation: Extracted volume (based on drum test)/ number of cycles counted during drum test.5 Extraction rate measured over drum test. Strictly for comparison to extraction rate based on counter readings.6 If NAPL detected, percentage (%) was calculated based on 88cm total depth. If sheen was noted on surface, NAPL was estimated at 0.1%.7 Extracted fluid based on average litres/cycle measured over previous three drum tests.8 NAPL based on average percentage of NAPL measured during two most recent drum tests x fluids extracted over period.9 NAPL discharge rate based on cumulative NAPL extracted over total time.

Average1Liquid pumped into a 210 litre drum over a measured period of time. 2Depth to water and NAPL (if present) in drum which is ~88cm deep.3Extracted volume calculated as: 210 litres - 2.4cm2*Depth to liquid.4 Calculation: Extracted volume (based on drum test)/ number of cycles counted during drum test.5 Extraction rate measured over drum test. Strictly for comparison to extraction rate based on counter readings.6 If NAPL detected, percentage (%) was calculated based on 84cm total depth. If sheen was noted on surface, NAPL was estimated at 0.1%.7 Extracted fluid based on average litres/cycle measured over previous three drum tests.8 NAPL based on percentage of NAPL measured during last drum test x fluids extracted over period.

Average 0.37 01Liquid pumped into a 210 litre drum over a measured period of time. 2Depth to water and NAPL (if present) in drum which is ~88cm deep.3Extracted volume calculated as: 210 litres - 2.4cm2*Depth to liquid.4 Calculation: Extracted volume (based on drum test)/ number of cycles counted during drum test.5 Extraction rate measured over drum test. Strictly for comparison to extraction rate based on counter readings.6 If NAPL detected, percentage (%) was calculated based on 84cm total depth. If sheen was noted on surface, NAPL was estimated at 0.1%.7 Extracted fluid based on average litres/cycle measured over previous three drum tests.8 NAPL based on percentage of NAPL measured during last drum test x fluids extracted over period.
