1.0 INTRODUCTION
1.1 Terms of Reference
ENG-TECH Consulting Limited (ENG-TECH) was retained by City of Winnipeg to conduct aPhase II Environmental Site Assessment (ESA) near the abandoned Gasoline and Diesel aboveground storage tanks (ASTs) and former underground storage tanks (ASTs) at 849 RavelstonAvenue in Winnipeg, Manitoba. The Site is located on Ravelston Avenue northwest of PlessisRoad in the City of Winnipeg, Manitoba as shown in Figures 1 and 2, and Photographs 1 to 4(Appendix B). Assessment is related to the area near the current aboveground diesel andgasoline storage tanks and the former underground storage tanks located to the northwest ofthe existing building, any previous tanks, pumps, and spillages beyond the areas of the AST’sand UST’s are outside this scope of work. In this report, the property will subsequently bereferred to as the Site with the investigation limited to the area near the tanks as mentionedabove.
ENG-TECH received authorization from Jennefer Larson to proceed with the Phase II ESA onMay 5, 2016.
1.2 Objectives
The purpose of the Phase II ESA was to further delineate the presence or absence of petroleumhydrocarbons in the soil in the vicinity of current ASTs and pump islands and in the location ofthe former USTs and pump island. The land use of the Site is currently commercial, and beingproposed for redeveloped having a mixture of commercial and residential buildings.
1.3 Scope of Work
The Phase II ESA involved the following:
• Clearance of underground utility services.
• A test hole drilling and soil sampling program for petroleum hydrocarbons, including fieldtesting the soil samples for volatile hydrocarbon vapours and the collection of duplicatesoil samples for petroleum hydrocarbon laboratory testing.
• A laboratory soil testing program for petroleum hydrocarbons (benzene, toluene, ethylbenzene, xylene (BTEX), and fractions Fl to F4), glycols, and metals.
• An evaluation of the results.
• An ESA report outlining the work conducted and findings.
1.4 Methodology
The environmental investigation was conducted using guidelines and criteria outlined inpublications from American Society for Testing and Materials (ASTM), the Canadian Council ofMinisters of the Environment (CCME), Canadian Standards Association and ManitobaConservation (formerly Manitoba Environment). A bibliography/reference list of the publicationsis attached.

2.0 SITE CONDITIONS
2.1 Site Location and Description
The Site is located on Ravelston Avenue northwest of Plessis Road in the City of Winnipeg,Manitoba as shown in Figures 1 and 2. The Site is approximately 6,344 square meters in plan,with buildings on Site which are currently unoccupied as the property is schedule forredevelopment, and registered in the City of Winnipeg under certificate of roll number04005426500. The remainder of the Site is predominately covered with asphalt and limitedgrass area as shown in Figure 2.
2.2 Site Topography and Drainage
The Site is relatively flat with surface drainage directed overland to catch basin locatedthroughout the Site and on Ravelston Avenue.
2.3 Site Geology and Groundwater
Local geological maps and water well logs show that the subsurface stratigraphy in this area ofWinnipeg normally consists of fill soils (such as topsoil and granular), underlain by lacustrine siltand clay ranging in depth from 9.0 to 12.0 m. A deposit of silty till varying in thickness from 6 to10 m is typically encountered between the lacustrine deposits and the underlain bedrock.Bedrock in this area of Winnipeg typically consists of dolomite with limestone beds of variousthicknesses from the Selkirk Member of the Red River Formation. The bedrock formation wasformed from the Paleozoic Era during the Ordovician Period.
Near surface groundwater elevations (perched groundwater) can exist at the Site andthroughout the area, and will vary on a seasonal basis and from site to site. Perchedgroundwater elevations are predominantly controlled by site conditions, such as the type andthickness of fill soils. The near static groundwater elevation is encountered at approximately 6m below existing grade in the underlain high plasticity lacustrine clay deposits. The near staticgroundwater elevation is controlled by the underlain bedrock aquifer. There are no aquifersabove the bedrock. The potential for impact to the aquifer was considered unlikely due to thethickness of the underlain highly plastic clay deposits.
3.0 PHASE II ESA
3.1 Test Hole Drilling
On May 24, 2016 ENG-TECH supervised the drilling of a total of nine (9) test holes (TH1 toTH9) surrounding the gasoline and diesel AST’s and the former UST’s located northwest of theAST’s. Test holes were drilled to a depth of 3.0 to 4.6 m below existing grade using a trackmounted Geoprobe 7822DT drill rig equipped with 125 mm diameter solid stem continuous flightaugers, owned and operated by Maple Leaf Drilling Ltd. The test holes were backfilled with thesoil auger cuttings and bentonite, upon the completion of drilling. The test hole locations areshown on Figure 2, while stratigraphic logs outlining the soil and groundwater conditions areshown in Appendix A.
3.2 Soil Sampling Program
Duplicate soil samples (set of two) were collected at regular depth intervals and at stratigraphicchanges from the test holes, and visually classified using the Unified Soil Classification System
![Page 7: APPENDIX A Phase II Environmental Site Assessment and](https://reader031.vdocuments.us/reader031/viewer/2022013015/61cfbcd89fe71b1bbb7f3a98/html5/thumbnails/7.jpg)
City of Winnipeg File No. 16-217-03Phase II ESA — 849 Ravelston Avenue, Winnipeg, Manitoba Page 3
(USCS). One of each duplicate set of soil samples collected was subjected to an AmbientTemperature Headspace (ATH) vapour test using a RKI Eagle calibrated using hexane. Briefly,the procedures used for ATH vapour testing were as follows:
• Collect a soil sample and remove the perimeter edges. Cut the sample into small piecesand place them into a plastic sealable bag.
• Induce air into the bag such that the bag is taught and seal the bag.
• Allow the vapours emanating from the soil to accumulate in the headspace of the bag atan ambient temperature for about 15 minutes.
• Measure the hydrocarbon vapour concentration in the headspace of the bag by placingthe probe of the RKI Eagle into the bag.
The remaining duplicate soil sample from each set collected had the perimeters edges removedand the sample examined for the presence of petroleum hydrocarbon odours and staining, andthen:
• If the remaining duplicate soil sample had visual signs of petroleum hydrocarbon stainingor petroleum hydrocarbon odours detected, then the soil sample was placed in a cleanglass jar and sealed with a Teflon lined lid and placed in a cooler packed with ice.
• If no visual signs of staining or odours were detected then the duplicate soil sample wasplaced in a sealed bag with a minimal volume of air, and then placed in a cooler packedwith ice for potential submission for laboratory analysis after review of the ATH vapourconcentration.
• The recorded ATH Vapour concentrations for all samples are reviewed, and if theduplicate soil samples with the highest elevated concentrations had not been placed injars, then the duplicate soil samples in the coolers were removed and the soil from thesealed bags placed in clean glass jars, sealed with Teflon lids and placed back in thecooler packed with ice.
Upon the completion of the field work, the soil samples in jars in the cooler packed with the icewere transported to ENG-TECH’s office, then to ALS Laboratory Group in Winnipeg, Manitobafor analytical testing of petroleum hydrocarbons.
3.3 Analytical Analyses
ATH vapour concentrations (ppm) collected in the field are reported on the test hole logs, andthe readings ranged from zero (0) to 240 ppm. Possible slight hydrocarbon odour and/orstaining was observed at TH5, TH6, and TH9.
Eight (8) representative soil samples (based on headspace) were selected and submitted toALS Laboratory Group (an accredited laboratory) and tested for BTEX and fractions Fl to F4.The results are shown in Tables I to 4, while a copy of the results from ALS Laboratory Groupis shown in Appendix C.
3.4 Remediation Criteria
The results from the analytical analyses were compared to the values outlined in the mostrecent Canadian Council of the Ministers of the Environment (CCME) publications. The
![Page 8: APPENDIX A Phase II Environmental Site Assessment and](https://reader031.vdocuments.us/reader031/viewer/2022013015/61cfbcd89fe71b1bbb7f3a98/html5/thumbnails/8.jpg)
City of Winnipeg File No. 16-217-03Phase II ESA — 849 Ravelston Avenue, Winnipeg, Manitoba Page 4
petroleum hydrocarbons BTEX and fractions Fl to F4 results were compared to the CCMEgeneric and vapour inhalation criteria for commercial land use. Generic criteria for commercialland use would not restrict Site commercial activities. Given the potential for futuredevelopment of the Site as residential land-use an assessment of the analytical results forBTEX and fractions Fl to F4 following the CCME generic and vapour inhalation criteria forresidential land use is warranted.
3.5 Discussion
Stratigraphy
Aboveground Storage Tank and Pump Island
Overall, the stratigraphy at TH1 to TH4 in the vicinity of the AST’s consisted of 200 mm thicklayer of concrete underlain by a 50 mm thick layer of gravel fill, and was followed by a 965 mmthick layer of clay fill which was underlain by native clay to the depth explored. The gravel fillwas medium brown, moist, medium dense, poorly graded, and fine grained, while the clay fillwas black, moist, firm, medium plastic, and contained trace silt. The underlying native clay wasmedium, moist, firm, highly plastic, and contained trace silt.
Former Underground Storage Tank Nest
The stratigraphy at TH5 and TH6 consisted of 2.30 to 4.1 m thick layer of pea gravel which wasfollowed by clay to the depth explored, except at TH6 where auger refusal occured 4.10 mbelow grade on suspected concrete rubble, The pea gravel encountered was medium brown,moist to wet, loose, poorly graded, medium to fine grained, with a slight hydrocarbon odourdetected at 0.8 m below grade. The native clay layer encountered at TH5 at 2.30 m below gradewas dark brown, moist, firm, medium plastic, and contained trace silt.
The stratigraphy at TH7 and TH8 consisted of 50 mm thick layer of gravel fill that was underlainby a 1.17 m thick layer of clay fill then native clay to the depth explored. The gravel fill layer wasmedium brown, moist, medium dense, poorly graded, fine grained while the clay fill layer wasdark brown, moist, firm, medium plastic, and contained trace silt. The native clay was darkbrown, moist, firm, medium plastic, and contained trace silt.
The stratigraphy at TH9 consisted of a 50 mm thick layer of gravel fill which was followed by a1.17 m thick layer of clay fill then native clay to the depth explored. The gravel fill and clay fillwere similar to what was encountered at TH7 and TH8. The native clay was dark brown, moist,firm, medium plastic, and contained trace silt.
Groundwater
TH1 to TH4 and TH7 to TH9 were dry and no sloughing was encountered at the time of drilling,while sloughing and seepage was encountered within the pea gravel at TH5 and TH6 at thetime of the drilling.
ATH Vapours
The ATH vapour readings are shown on the test hole summary logs. The vapourconcentrations ranged from zero (0) to 240 ppm. slight hydrocarbon odour and/or possiblestaining was observed at TH5, TH6, and TH9.

Analytical Results
The petroleum hydrocarbons BTEX and fractions Fl to F4 results were compared to the CCMEgeneric and vapour inhalation criteria for both commercial and residential land use due to thepotential for future residential development of the Site. Generic criteria for commercial land usewould not restrict Site commercial activities.
In the generic situations for both commercial and residential land use the soil sample from TH4—S4 at 3 m was over the CCME criterion for benzene and TH5-S2 at 0.8 m was over the F2criterion as shown on Table 1. When the results were compared to vapour inhalation forcommercial and residential both sample results were below the applicable CCME criteria asshown on Tables 2 and 4. The remaining samples collected and analysed for petroleumhydrocarbon were all below the laboratory detection limits and therefore below the applicablecommercial and residential CCME guidelines under the generic and vapour inhalation criteria.
3.6 Conclusions
Petroleum hydrocarbon concentrations from the soil samples tested from TH4 and TH5 wereabove select CCME criteria for commercial and residential land uses under the genericsituation, but were below the applicable vapour inhalation criteria for both commercial andresidential land uses. Therefore, no further action is warranted at this time in the vicinity of theASTs and former USTs.
Additional sampling and testing can be performed beneath the tanks and pump island duringtheir removal as per the Guideline for Dismantling and Removal of Petroleum Storage TanksSystems (Manitoba Conservation February 2007), with extra attention in the area of TH4 due tothe presence of benzene.
4.0 CLOSURE
The conclusion and recommendations presented in this report were based on the scope of workoutlined for the purpose of the investigation, and were prepared in accordance with acceptedprofessional engineering/geo-science principles and practices. However, as with anyenvironmental site assessment the intent is to identify and address, not eliminate, potentialenvironmental concerns.
The observations made at the Site do not apply to areas which could not be observed. Inaddition, other materials or compounds not investigated or addressed or beyond the scope ofwork could be present at the Site. If this occurs, ENG-TECH Consulting Limited must benotified to determine whether modification to any part of this report should be conducted. If youhave any questions or concerns presented herein, please contact the undersigned.

BTEXS+F1-HSMS-WP Soil BTX plus Fl by GCMS EPA 826CC
The soil methanol extract is added to water and reagents, then heated in a sealed vial to equilibrium. The headspace from the vial Is transferred into agas chromatograph. Target compound concentrations are measured using mass spectrometry detection.
F1-F4-CALC-WP Soil CCME Total Hydrocarbons CCME CWS-PHC, Pub #1310, Dec 2001-SAnalytical methods used for analysis of CCME Petroleum Hydrocarbons have been validated and comply with the Reference Method for the CWS PHC.
In cases where results for both F4 and F4G are reported, the greater of the two results must be used in any application of the CWS PHC guidelines andthe gravimetric heavy hydrocarbons cannot be added to the C6 to C50 hydrocarbons.In samples where BTEX and Fl were analyzed F1-BTEX represents a value where the sum of Benzene, Toluene, Ethylbenzene and total Xylenes hasbeen subtracted from Fl.
In samples where PAHs, F2 and F3 were analyzed, F2-Naphth represents the result where Naphthalene has been subtracted from F2. F3-PAHrepresents a result where the sum of Benzo(a)anthracene, Benzo(a)pyrene, Benzo(b)fluoranthene, Benzo(k)fluoranthene, Dibenzo(a,h)anthracene,Fluoranthene, lndeno(1 ,2,3-cd)pyrene, Phenanthrene, and Pyrene has been subtracted from F3.
Unless otherwise qualified, the following quality control criteria have been met for the Fl hydrocarbon range:1. All extraction and analysis holding times were met2. Instrument performance showing response factors for C6 and Cl 0 within 30% of the response factor for toluerie.3. Linearity of gasoline response within 15% throughout the calibration range.
Unless otherwise qualified, the following quality control criteria have been met for the F2-F4 hydrocarbon ranges:1. All extraction and analysis holding times were met.2. Instrument performance showing ClO, C16 and C34 response factors within 10% oftheiraverage.3. Instrument performance showing the C50 response factor within 30% of the average of the dO, C16 and C34 response factors.4. Linearity of diesel or motor oil response within 15% throughout the calibration range.
F2-F4-TMB-FID-WP Soil CCME Total Extractable Hydrocarbons CCME CWS-PHC, Pub #1310, Dec 2001A soil or sediment sample is extracted with 1:1 hexanelacetone In a tumbler, followed by a silica gel clean up to facilitate separation of the hydrocarbonsfrom other polar extractions. An aliquat of the solvent Is analyzed using a gas chromatograph equipped with a flame -ionization detector.MOISTURE-WP Soil % Moisture CCME CWS-PHC, Pub #1310, Dec 2001Moisture content in solid matrices is determined gravimetrically after drying to constant weight at 105cC.

This will acknowledge receipt of the Remediation Plan for the above noted property (the site)dated July 13, 2016 and prepared by Eng-Tech Consulting Limited.
The Rernediation Plan states:

• Site rernediation via excavation of the contaminated soil above the Canadian Council Ministers ofthe Environment (CCME) criteria for residential land use is being proposed and is a viableremedial option since the land may be used for residential purposes. The excavation would belimited to the area of the former underground and above ground storage tank nest and will extenduntil all contaminated soil above the CCME criteria for residential land use is removed.
• The contaminated soil will be hauled to either the Prairie Green Soil Facility in the RM of Rosseror Brady Road Landfill.
• The soil below the CCME criteria will be temporarily stockpiled on site and placed back into theexcavation upon removal of the contaminated soil and confirmatory testing of the soil along theexcavation walls and base.
