1. Introduction

1.1 Project Overview The proposed Bridge Road Pump Station and Conveyance System for the North Shore Waste Water Treatment

Plant (NSWWTP) will be located in North Vancouver, connecting sewers in proximity of the existing Lions Gate

Waste Water Treatment Plant (LGWWTP) and conveying wastewater to the NSWWTP on West 1st

Street. A new

wastewater conveyance pump station will be located on Vancouver Fraser Port Authority (Port) land. The SMP

has been developed for the proposed conveyance system which includes a new pump station, associated influent

sewer and forcemain and effluent sewer that will be located adjacent to the existing LGWWTP under the Lions

Gate Bridge, within the Vancouver Fraser Port Authority jurisdiction. See Figure 1-1 for the site location. The

Conveyance Route is a pipeline alignment of approximately 2 kilometres in length that extends from the area of the

existing Lions Gate Wastewater Treatment Plant, adjacent to a rail corridor and along District of North Vancouver

streets to the east (e.g. Philip Avenue). The Conveyance Route traverses the District of North Vancouver, and part

of the Squamish Nation (SN) Capilano IR#5 lands. The project is being delivered using a Design Build

procurement method.

This Draft Soil Management Plan (Draft SM Plan) was prepared by AECOM in support of Metro Vancouver’s Port

application for the Port’s Project and Environmental Review Process. This Draft SM Plan is designed to provide

guidance for handling and managing contaminated soil during construction of the proposed Project. The Draft SM

Plan is based on the indicative design of the proposed Project and on preliminary soils investigations. The Draft SM

Plan will be updated by the Design-Builder once both the detailed design of the proposed Project and the

construction plan are finalized. It is anticipated that further targeted investigative work will be subsequently

conducted to identify and characterize contaminated soils, and that management procedures for handling

contaminated soils will be updated to reflect the updated design and construction logistics.

1.2 Soil Quality Study Construction activities for the proposed Project will include site clearing, site preparation, and soil excavation.

These construction activities will disturb soils and therefore have the potential to mobilize contaminated soil that

might exist within the proposed Project footprint. To assist in identification of areas within the proposed Project

footprint where the potential for mobilization of contaminated soils exists, an initial Soil Quality Study was

undertaken. The Soil Quality Study focussed on characterizing the existing soil chemistry within the proposed

Project footprint, including comparison of the soil chemistry data with soil quality standards and guidelines. Work

conducted to support the Soil Quality Study included a review of available historical environmental assessment and

remediation reports for the Site, a search of the BC Ministry of Environment (MOE) Site Registry, and determination

of soil quality in areas where soils are expected to be disturbed or removed.

1.3 Site Location and History of Use The Project includes three major pipelines and a pump station. The major pipelines consist of the following:

1200 mm Influent Sewer

900 mm Forcemain

2100 mm Effluent Sewer

1.3.1 Influent Sewer

The Influent Sewer consists of a 1200 mm sewer extending east from the existing Lions Gate Treatment Plant

and then south from the existing treatment plant adjacent to the Lions Gate Bridge alignment within the MOTI

ROW to the new pump station.

1.3.2 Forcemain

The forcemain consists of a 900 mm pipeline extending north from the new pump station adjacent to the Lions

Gate Bridge alignment within the MOTI ROW and then east following the CN Railway alignment to Whonoak

Road. At Whonoak Road, the forcemain turns north following the Whonoak Road alignment and then east

along W 1st St to Philip Avenue where it will connect to the NSWWTP.

1.3.3 Effluent Sewer

Effluent from the NSWWTP will flow through a 2100 mm pipeline extending from W 1st Street and Philip Avenue

west along W 1st Street until Whonoak Road. At Whonoak Road, the effluent line will turn south to the CN

Railway and then turn west and follow the CN Railway alignment to the Lions Gate Bridge where it will turn south

and follow the bridge alignment within the MOTI ROW to the existing outfall.

1.3.4 Pump Station

The pump station will be located within the MOTI ROW approximately 30 m south of the North Cable Bent of

the Lions Gate Bridge. The site is within the Vancouver Fraser Port Authority (Port) boundary.

Metro Vancouver




The Conveyance Route consists of a linear corridor dedicated to the forcemain and effluent pipelines

approximately 2 kilometres in length and described as follows: Starting at the new pump station site and

running north along the MOTI ROW (Bridge Road alignment). It crosses the rail corridor, to an undeveloped

area between the Capilano Highway Services (CHS) works yard and the rail corridor. After crossing the rail

corridor, the alignment goes east, extending along the north side of the rail corridor, and south of the Squamish

Nation (IR#5) lands, to the extension of Whonoak Road. The alignment goes north along the extension of

Whonoak Road to 1st Street West. The alignment becomes easterly along 1st Street West, and extends to the

proposed NSWWTP near the corner of 1st Street West and Philip Avenue. The Conveyance Route parallels the

current North Vancouver Interceptor sewer. In the western part of the alignment, the route extends through

undeveloped lands. The eastern section of the route is situated within the District of North Vancouver streets.

There are no known structures or buildings located directly on the alignment, except for a landscaping company

on the Whonoak Road extension.

Activities and uses for the proposed Site include freight handling, light industrial and commercial operations, rail

transportation, works yards, wastewater treatment, parkland and undeveloped land. Due to activity over the

decades in the vicinity of the proposed Site, fill has most likely been placed over certain areas. Please refer to the

2017 Limited Baseline Study/Phase I Environmental Site Assessment (AECOM, 2017) for details.

The pump station is situated on Federal land under the administration of the Vancouver Fraser Port Authority. The

conveyance alignment crosses Squamish Nation and the District of North Vancouver. Zoning (i.e. land use) for

the pump station and conveyance route includes industrial, commercial and residential.

The site stratigraphy consists of sedimentary rocks of the Nanaimo group (MFLNRO, 2014). The surficial geology

is Quaternary Post-Glacial Salish Sediments, with lowland and mountain stream deltaic, channel fill and overbank

sediments including medium to coarse gravel and minor sand, up to 15 metres or more in thickness.

1.4 Project Description The existing Lions Gate Waste Water Treatment Plant (LGWWTP) serves the North Shore municipalities of the

District of West Vancouver (DWV), the City of North Vancouver (CNV), and the District of North Vancouver (DNV),

as well as the Squamish Nation and Tsleil-Waututh Nation. The plant was originally commissioned in 1961 and has

provided primary-level treatment on the North Shore for the past 50 years. The existing plant will continue in

operation until the NSWWTP is commissioned and operating. The project is part of a secondary upgrading

program from the two remaining primary WWTPs in the Metro Vancouver region. It is required to be upgraded by

the end of 2020.

The Project comprises the construction of a Pumping Station directly beneath Lions Gate Bridge, adjacent to the

existing LGWWTP and conveyance piping as described above.

The land use along the site includes:

Rail lines to the south

New vehicle and pedestrian overpass west of the site on Philip Avenue

Light commercial businesses to the north of 1st

Street

Residential neighbourhood (Norgate) to the north of the project, in North Vancouver

Recreation trail (Spirit Trail) located approximately 75 m north of the site

Higher density residential development and commercial activities to the north and along the Marine Drive

corridor

Pemberton Avenue to the north with light industrial and commercial buildings

McKeen Avenue to the east and south of the site, with light industrial and commercial activities

Metro Vancouver




Kinder Morgan, FibreCo and Seaspan to the south of the site.

The project is at the indicative design stage currently. Construction methodologies and detailed plans are not

included in this Soil Management Plan. Based on up-to-date knowledge, the following activities are expected to

take place:

Operation of heavy machinery and other fuelled equipment (i.e. pumps and generators).

Clearing of vegetation including mature timber from the proposed alignment.

Removal and disposal of invasive species.

Trenching excavation and pump station locations up to 15 metres below ground surface (bgs).

Stockpiling handling and disposal of soils.

Structural fill importation and placement.

Cementitious material use and cast-in-place pouring to build the pump station and install associated

appurtenances.

Recovery, treatment and disposal of groundwater and precipitation from excavation areas.

Restoration of vegetated areas post-construction.

Some operational activities include:

Scheduled inspection and maintenance of the constructed sewer conveyance, and

Vegetation maintenance (i.e. mowing, brushing) within the completed conveyance right-of-way.

Metro Vancouver




2. Regulatory Framework

The site falls under both federal (i.e. Port and first nation reservations) and provincial jurisdictions. Therefore, the

soil quality was compared to both the Canadian Council of Ministers of the Environment (CCME) guidelines and the

provincial standards. If contaminated soils from the federal jurisdictions cannot be managed within the federal

jurisdictions and must be removed for disposal on provincial lands, then provincial law (the BC Environmental

Management Act) and standards (Contaminated Sites Regulation) apply.

2.1 Federal Guidelines Based on the current land use at the Site, CCME Guidelines for Residential Land (RL) use are applicable for

evaluation of soil quality (CCME 2007).

A review of Map 1486A Surficial Geology, Vancouver, British Columbia: Geological Survey of Canada 1976

indicates that the surficial geology at the Site and surrounding properties consists of lowland and mountain stream

deltaic, channel fill and over bank sediments of the Salish Sediments Group. This stratigraphy consists of mountain

stream and marine deltaic medium to coarse gravel and minor sand up to 15m thick. The Site has a generally flat

topography and is unpaved.

The CCME Canada-Wide Standards for Petroleum Hydrocarbons (PHC) in Soil is a remedial standard for

petroleum hydrocarbon impacted soil and subsoil under four land use categories. The standard is grounded in risk

assessment and can be applied at any of three “Tiers”: Tier 1 – generic numerical levels; Tier 2 – adjustments to

Tier 1 levels based on site-specific information; Tier 3 – site-specific risk. In the case of the subject site, Tier 1 was

used.

The groundwater for the site was compared the CCME drinking water guidelines. During the detailed design

process, the disposal options for the extracted groundwater will be defined at which time the groundwater

concentrations should be compared to the appropriate guidelines (i.e. ambient marine water quality guidelines, etc.)

2.2 Provincial Standards The Contaminated Sites Regulation (CSR) is the principal legislation defining requirements for contaminated sites

management in BC. The CSR has been amended several times since it was promulgated in 1997, with the most

recent significant changes in effect made on 25 January 25 2014: the Stage 9 Amendments. The most recent

amendments were published in October 2016, to come into effect November 1, 2017. They are known as the Stage

10 Omnibus amendments to the CSR. The BC Environmental Management Act (EMA) and CSR have provisions

for both numerical and risk-based standards to apply in managing site contamination. The CSR stipulates the

procedures for site assessment, remediation, and application for environmental closure of a property. Numerical

standards in the CSR can be used as screening values when assessing whether a site is contaminated. Generic

and matrix numerical standards for soil are listed in Schedules 4, 5, and 10 of the CSR and broken into four

categories based on land use: parkland, residential, commercial, and industrial. For the matrix numerical standards

(Schedule 5 of the CSR), the land use categories were further broken into site-specific factors. Site-specific factors

for human health protection (“human intake of contaminated soil”) and environmental protection (“toxicity to soil

invertebrates and plants”) apply at all sites; therefore, these standards were used in evaluating soil quality. Given

the close proximity to Burrard Inlet, the site-specific factor for environmental protection (“groundwater flow to

surface water used by aquatic life”) has also been applied in evaluating soil quality. Further, both the EMA and the

CSR allow for the relocation of soil from one site to another site, subject to the quality of the soil. As an example,

Metro Vancouver




soil from a contaminated site that has concentrations of contaminants of concern (COCs) below the industrial land

use standards can be relocated to an industrial land use site. If the soil quality exceeds the “trigger values” set out

in Schedule 7 of the CSR, a contaminated soil relocation agreement is required.

Soil Management must be completed with the most current CSR standards. Changes to the CSR Standards have

been announced recently and will come into effect on November 1, 2017. These will be the Stage 10 Omnibus

amendments.

The groundwater results were compared to the provincial drinking water standards. As noted in Section 2.1, during

the detailed design process, the disposal options for the extracted groundwater will be defined at which time the

groundwater concentrations should be compared to the appropriate provincial guidelines (i.e. ambient marine water

quality guidelines, etc.)

Metro Vancouver




3. Summary of Available Environmental Information

3.1 Study Methods and Scope AECOM reviewed available historical environmental assessment reports to provide an understanding of historical

and anticipated soil contamination in areas from where soil is expected to be removed. The geographic boundaries

for characterizing soil contamination (Soil Study Area) include all construction areas where excavation activities

associated with the proposed Project could take place (Figure 3-1). No new soil testing was done as part of this

characterization, but the information was used to develop recommendations for further soil investigation.

The areas of potential excavation activity (Figure 3-1) are summarized below and include the area surrounding the

proposed pump station location, as well as all along the conveyance route realignment corridor.

The infrastructure required for this project will necessitate excavating below the fill layer, which contains

contaminated soil. As such, all of the excavated spoil material that is contaminated soil will need to be removed

from the site and disposed in a licensed facility or at another site under a soil relocation agreement. The Design-

Build Contractor will need to perform additional investigation and testing in order to identify contaminated materials.

In addition, groundwater will be extracted from the site during dewatering activities but will need to be treated prior

to discharge, either on-site or at a licensed facility. Steps to minimize groundwater extraction may be taken,

including the installation of cut-off walls along the southern property boundary.

3.1.1 Previous Investigations

Previous investigations identified areas of potential environmental concern (APECs) and their associated potential

contaminants of concern (PCOCs) and contaminants of concern (COCs) in locations across the Soil Study Area.

These investigations are summarized below.

Unless otherwise noted, concentrations described in these reports were reviewed against the current

applicable soil guidelines and standards. Previously identified soil exceedances are still considered

exceedances. In a few instances, however, additional parameters (e.g., metals) not previously identified are

now considered exceedances due to updated standards. Further, due to the proximity of the soil to Burrard

inlet, the salinity in the soil may limit the disposal options and have been included as a parameter that requires

assessment as well.

3.1.2 BC MOE Site Registry Search

The contaminated sites provisions under the EMA and CSR require the Province to provide public information

about site investigations and cleanups. The Site Registry was established to meet this requirement. The Site

Registry documents milestones in the site assessment process and provides public access to this information.

It contains information regarding sites that have been investigated, remediated, or both in BC since 1988 when

the BC MOE began recording these activities. The Site Registry also includes sites for which a Site Profile has

been submitted.

On March 19, 2017, AECOM searched the Site Registry and identified 2 records for properties within a 0.5 km

radius of the Soil Study Area. An independent BC Site Registry search was conducted to locate any records

entered since October 2012, which is the date up to which Ecolog ERIS accounts for. A detailed report was

only obtained for properties that pose an environmental concern for the Site and were not accounted for in

Ecolog ERIS search. Three registered sites were identified within 1km2

of the Site. Two sites (Site ID: 4802

and 12383) were not identified by Ecolog Eris. A detailed report was obtained for both sites. A summary of

the result is provided in AECOM’s Baseline/Phase I ESA (March, 2017).

3.2.2 Golder Associates. 2015. Stage 2 Preliminary Site

Investigation Conveyance Route, North and West Vancouver, BC Report

This report assessed the APECs identified in the Stage 1 PSI to evaluate whether they represented actual

areas of contamination. The investigation found some APECs related to historical land use and/or filling

activities. The source of the fill is unknown. The groundwater had metal concentrations which exceeded the

CSR regulations. As a result of the investigation, the following recommendations were outlined:

Consider developing a soil and water management plan to be used during construction. This Plan

should include outlining procedures to follow and address issues associated with identification,

handling and disposal of contaminated and potentially contaminated soil and groundwater.

Disposal options for contaminated soil (i.e. RL and CL exceedances).

Consider further investigating subsurface conditions in areas of higher risk and/or concern of finding

contamination.

Consider arranging for proper disposal of excavation water during construction.

The DB contractor should develop a site-specific health and safety plan.

Vapour samples should be collected from the conveyance alignment in order to assess whether there

are concerns for trench workers who may be working in confined spaces during construction.

Wherever access was not possible during the Stage 2 PSI, these areas should be assessed in order

to determine whether there are soil and groundwater contamination concerns.

3.2.4 Hemmera, 2005. Final Report. Sediment Investigation and Habitat Assessment. Pacific Environmental Centre (PEC) Site, West Vancouver, BC

Hemmera completed a sediment and habitat investigation at Environment Canada’s Pacific Environment Centre

(PEC) site, situated in West Vancouver, along the north shore of Vancouver Harbour in Burrard Inlet. Historical

filling and industrial activities on and adjacent to the PEC site resulted in metal sulphide, sulphur and asphalt/tar

contamination on soil, groundwater and sediments. The study identified three areas of potential environmental

concern (APECs): Low Lying Area (LLA), Lagoon Area (LAG), and the Burrard Inlet Foreshore Area (BIF). The LLA

had the highest metal concentrations of the 3 areas. Copper, lead, zinc and PAH concentrations were found to

be lower in the other two areas but they exceeded the Sediment Quality Guidelines of the time. The report

recommended a more thorough delineation of potential contamination and risk to biota in the following areas:

Vertical extent of contamination in the LLA and LAG

Season variation in LLA water quality and toxicity

Additional sediment toxicity testing in the BIF and LAG

Benthic community analysis in the BIF and LAG

Metal bioaccumulation in bivalves in the BIF and LAG

Extent of upland contamination adjacent to all three areas: LLA, LAG and BIF

Transport of potential contaminants of concern via surface water runoff and groundwater to the three areas;

and

Sediment transport pathways and mechanisms in the three areas.

The objective of this Phase I Environmental Site Assessment was to screen the Capilano Reserve #5 for

contaminant risks. The risk categories were considered as: none, actual, potential, and actual/potential

contamination. The contaminant risks were ranked as low, moderate or high priority. The report identified 2 high

priority locations:

Imported fill in Parcel G that was being developed for residential use.

Active dumping of refuse.

In addition, eight low to moderate priority locations were identified, with potential, actual or actual/potential

contamination.

The report identified twelve environmental risks of potential contamination:

3.2.7 2017 AECOM Investigations

AECOM Canada Ltd. conducted a limited Soil Investigation sampling program in February of 2017, as a follow up

to a geotechnical investigation conducted by Golder Associates Ltd. (Golder) in December 2014, along the

Conveyance corridor between the current LGWWTP and the location of the proposed NSWWTP. Golder

performed a geotechnical evaluation along a portion of the conveyance route in the vicinity of the proposed pump

station and under the Lions Gate Bridge on February 6, 2017, with the advancement of five borehole locations.

AECOM personnel collected soil samples during the intrusive investigation. The Site investigated is considered an

APEC: Lions Gate Bridge. However, Golder did not measure soil salinity during their December 2014 field work.

AECOM analyzed for soil salinity in its field program of February 2017. AECOM believes this is a gap in Golder’s

investigation which may impact decisions on how soil should be managed. Therefore, until all soil within the APECs

has been properly delineated, AECOM will assume that it is all impacted. Furthermore, CCME exceedances and

Metro Vancouver




ownership of the Pumping Station area by Port may limit the use of the site. The soil may be used for dyking or

foreshore infill, depending on whether the soil quality is acceptable by the Port.

Based on the analytical results, and pursuant to CSR Stage 10 Omnibus Standards and the CCME RL

Environmental Quality Guidelines, additional soil characterization of salinity is recommended during the Design

Build stage to assess the soil salinity and help guide the disposal options.

AECOM Canada Limited (AECOM) was retained by Metro Vancouver to conduct a Limited Baseline Study/Phase I

Environmental Site Assessment (ESA) for one property located within West Vancouver, British Columbia within the

jurisdiction of the Port. APECs and PCOCs are summarized in Table 3-2 below.

3.2.8 Summary of Environmental Investigations

AECOM identified nine on and off-site APECs in the area. Of the nine APECs, only five will be affected by the soil

excavation activities. Based on the available soil and/or groundwater quality, all five APECs are areas of

environmental concern (AECs). A summary the APECs and why they are AECs is in Table 3-3, below. This table

summarizes the existing information Tables with the analytical data are included in Appendix B. Figures with the

analytical data are included in Figures 4-1 to 4-5. The original analytical data is included in the original reports that

are referenced in this report and summarised in the previous sections. Soil vapour data was not collected during

any of the investigations.

In addition to the above media not analyzed (from Table 3-3 above), the soil salinity for the entire area of

excavation should be assessed as part of future investigations.

3.2.9 Recommendations for Additional Investigation and Sampling

Based on the information gathered in the previous section and as part of construction planning, further soil and

groundwater investigation should be completed by the Design-Builder to resolve the data gaps identified in Table

3-3.

Further, while the AECs, and COCs for some of the areas identified in Table 3-3 were characterized by previous

environmental investigations, the Design Builder may want to re-characterize, to account for any activities that may

have contaminated the soil since those investigations took place. This effort will likely include updated estimates of

the volume of any contaminated soil.

Based on the history of the APECs identified, there continues to be potential for soil contamination to be present in

some of them (Figure 3-1). The Design Builder may want to do further investigation as part of its due diligence.

Soil should be characterized prior to excavation using the BC MOE’s Technical Guidance 1 – Site Characterization

and Confirmation Testing (TG1) (BC MOE 2009). Per TG1, soil testing will be completed in situ, except for areas

where excavated soil quantities are expected to be negligible and in situ characterization is not feasible, in which

case ex situ testing may be completed. Once soil testing and analysis are completed, and if soil concentrations are

below the CSR standards and CCME guidelines, the soil may be re-used on-site.

The following areas should be tested for the following PCOCs and COCs in soil and/or groundwater:

Soil salinity: Along the alignment heading east, extending along the north side of the rail corridor, and

south of the Squamish Nation (IR#5) lands, to the extension of Whonoak Road. Then north along the

extension of Whonoak Road to 1st Street West. Again easterly along 1st Street West, and to the

proposed NSWWTP near the corner of 1st Street West and Philip Avenue.

4. Management Procedures during Excavation Activities

As described in Section 3, there are several areas where the levels of contamination in the soils exceed federal and

provincial criteria and there is the potential for more or new contaminants to have accumulated in the soils. To

mitigate the risk of disturbing unknown areas of contamination, further investigations should be completed prior to

construction activities by the Design-Builder to address the media not analyzed in Section 3.2.9.

The following subsections provide general guidance on how soil will be managed during construction. This

guidance will be updated once the Soil Management Plan is finalized during construction planning after detailed

investigations are completed.

4.1 Roles and Responsibilities Port Metro Vancouver is committed to minimizing potential negative environmental effects through avoidance and

by implementing best management practices (BMPs) and other appropriate mitigation measures. Roles and

responsibilities for finalizing and executing environmental management plans during construction, including this Soil

Management Plan, are defined in the Construction Environmental Management Plan (CEMP). The CEMP provides

a framework for the required component plans, the roles of key environmental staff members, reporting

requirements1, and identified areas of environmental risk. The objective of the CEMP is to present mitigation

measures, BMPs, and guidance for component plans that may be required to avoid or minimize adverse project

effects.

The current plan for delivery of the proposed Project uses a design-build contract methodology. This process

requires the successful DB Contractor to finalize the design with the most efficient construction methods for the

proposed project. The CEMP sets out the minimum BMPs for the proposed Project and will be refined and further

developed by the DB Contractor, based on the final design and their selected methods for carrying out the

construction.

4.2 Soil Management Any activities during which contaminated and suspected contaminated soil will be removed from the ground will

require monitoring by a qualified professional. The qualified professional will:

Monitor excavated soil for visual indications of contamination, such as the presence of black staining, ash,

debris, odours or volatile vapours.

Field screen for volatile vapours by using a portable combustible gas monitor, and field screen for metals

by using an X-ray fluorescence analyzer.

Issue manifests specific to the contaminant type and CSR classification.

Track volumes of soil removed from the Site.

Supervise implementation of BMPs to limit soil migration and runoff.

1 Roles and reporting requirements will be added when the DB Contractor updates the plan.

Metro Vancouver




4.2.1 Best Practices for Management of Contaminated Soil

Best Management Practices (BMP) for managing contaminated soil includes:

Refining the design to avoid, where practical, areas of soil contamination.

Minimizing excavation areas.

Re-using uncontaminated soil as backfill within the proposed Project boundary, to the extent possible.

Limiting excavations to depths above the groundwater table, wherever possible.

Limiting dewatering activities, to the extent possible.

Dewatering excavation sites in a manner such that discharge water will meet CCME water quality criteria

before being released to the receiving environment.

Once the detailed environmental investigations are completed, the soil management plan should include specific

details on how the contaminated soil will be managed using the best practices noted above.

4.2.2 Field Screening

Remedial excavation limits will be based on available data, and on visual and olfactory evidence, as well as field

measurements. Visual monitoring will include evidence of staining, evidence of hydrocarbon product, hydrocarbon

or solvent-like odours and construction debris. Soil samples will be collected at regular intervals and locations for

field screening. Soils will be field screened for volatile vapours using a portable flame ionization detector (FID),

such as an Eagle RKI calibrated with hexane gas, using the following procedure:

Soil samples will be placed into sealable plastic bags immediately to allow measurement of headspace

analysis of volatiles with the FID. The bag will be allowed to rest for approximately 5 minutes. The probe of

the FID will be inserted into the bag and the minimum headspace vapour measurement will then be

measured and recorded.

Soil samples from the sealable plastic bags will be also be field screened for metals using an x-ray

fluorescence analyzer.

4.2.3 Management of Suspect Material

The following BMPs will be applied as part of the soils management component of the CEMP (submitted under

separate cover).

Stockpiling of Soil. Soils will be characterized in situ (in the ground) to enable identification of spatial relationships

between contaminated sources and contaminated materials, making the nature and extent easier to determine. If

any suspect soil is stockpiled on-site, PCOCs associated with the location from where the soil was removed will be

sampled in a manner consistent with the MOE protocol contained in TG1.

AECOM compared the soil analytical results for all of the planned soil excavation areas against applicable CSR

Stage 10 standards and CCME guidelines. The results are tabulated in Tables 1 through 6 and shown in Figures

4-2 through 4-6 and discussed in Section 3.2.8. Soil contamination was found in the following APECs (Figure 4-2)

and Table 3-4:

Additional soil contamination may be present in these APECs and that data gap should be resolved prior to

removing the soil off-site or disposing of the soil on-site.

Stained Soil. If staining or wood debris are encountered during the excavation, the soil will be treated as

suspect, and isolated, characterized, and contained within an appropriate holding container. If required, it

will be disposed of at a licensed off-site facility upon receipt of analytical results from the project laboratory.

Sample(s) will be analyzed for PCOCs associated with the area where the excavation took place.

Non-Aqueous Phase Liquid (NAPL). If NAPL is identified during excavation activities, affected soil will be

segregated and treated as hazardous waste per the Hazardous Waste Regulation. However, during the

previous investigations, there was no indication of NAPL present.

Stockpile Location. Soils will be stockpiled in a way that eliminates direct or indirect discharge of

deleterious substances to water frequented by fish. Stockpiles will be staged in a location as far away from

Burrard Inlet as possible. Stockpiles will be protected to minimize migration and runoff (i.e., using surface

berms and impermeable materials such as polyurethane to prevent weathering and erosion of stockpiles).

They will be transported to a designated facility as soon as practicable.

Metro Vancouver




Wash Stations. Truck wash-down stations will be implemented in dry conditions to minimize off-site soil

migration (air particulates or surface runoff).

Groundwater Elevation. The groundwater depth across the site is a minimum of 2.0 m bgs If any

excavation does penetrate the water table and sheens are observed in the trench, the water quality will be

assessed and appropriate action taken (i.e., dewatering, water treatment).

4.2.4 Debris Management

Debris, such as buried wood waste or other non-soil materials, may be encountered in the various fill layers at the

site. If debris is encountered, it will be separated from the soil and appropriately disposed of.

4.3 Backfill Procedures Where excavated material is contaminated, excavations will be backfilled with clean material from a documented

source. The DB Contractor will be responsible for the collection of samples of backfill material for chemical analysis

to confirm the material is not contaminated. The material quality will be confirmed by the chemical analysis and

comparison to the applicable regulatory standards prior to placement on the site.

4.4 Stockpile Management and Sampling Procedures While stockpiling and ex situ sampling are not anticipated to be a requirement, management and sampling

procedures will be developed as part of the finalization of the Draft SM Plan to address stockpile management if it

were to arise. These procedures will include requirements for appropriate siting of stockpiles and characterization

of soil using the MOE’s TG1. While MOE guidance is not applicable at this site, it does provide a best practice and

is applicable if the soil is taken off-site to provincially regulated land. The available soil quality data is summarized

in Section 4.2.3. Further investigation by the Design-Builder will be required to address the media not analyzed

(Table 3-3) outlined in Section 3.2.9. Once these investigations have been completed, further assessment should

not be required. However, if there is a need for further assessment, the following procedure is designed to

characterize suspect materials in stockpiles (ex situ) based on the MOE’s TG1. If required, soil stockpiles should be

segregated into three categories, suspect hazardous waste, suspect waste and suspect industrial quality soil,

pending testing and classification for disposal by the environmental consultant. TG1 specifies maximum stockpile

sizes, cell volumes and the number of representative cell samples required for each of these three classes.

In the event hazardous waste is encountered, the environmental consultant will provide advice on the temporary

storage of the material in accordance with the BC Hazardous Waste Regulation. Sampling and analysis of suspect

hazardous waste will be completed to determine actual contamination levels.

For each soil class a stockpile contains five cells and each cell has one representative cell sample. The following

steps are used to homogenize, split and analyze the cell samples:

Homogenize each cell sample.

Split each cell sample into two parts, and create two sets of split cell samples.

Prepare one composite sample from five samples of equal volume from one of the sets of split cell

samples.

Analyze the composite sample for PCOCs.

Randomly select two cell samples from the remaining set of five split cell samples.

Analyze the two randomly selected split cell samples individually for PCOCs.

Throughout the course of AECOM’s limited soil and groundwater investigation, it found exceedances mostly in the

subsurface (0.0 to 0.5 m) layer. These AECs can be considered waste that should be disposed in a licensed facility.

Metro Vancouver




4.5 Material Loading Procedures Care will be taken to avoid mixing clean and contaminated or suspect contaminated soil. This procedure will be

more fully developed once the recommended soil investigations have been completed and the soil quality in the

APECs and AECs is better understood. Weigh bills and associated analytical results will be used to document that

appropriate trucking and disposal methods are completed for the soil quality being loaded.

4.6 Disposal Plan for Contaminated Soil Once the recommended soil investigations have been completed and the final design of the proposed Project has

been approved, detailed soil disposal procedures will be developed by the Design-Builder. Potential soil disposal

facilities or receiving sites under a contaminated sites relocation agreement will be identified. Disposal options for

contaminated soils will be determined based on the chemical characteristics of the soil. Non-leachable soil with

COCs that exceed the CSR IL standards or CCME RL Guidelines will be disposed at one of the licenced landfills in

the Lower Mainland as well as soil that exceeded chloride and sodium CSR IL standards. Furthermore, CCME

exceedances and ownership of the Pump Station area by the Port may limit the use of the site. The soil may be

used for dyking or foreshore infill, depending on whether the soil quality is acceptable by the Port.

4.7 Traffic Management Plan Once the areas of contaminated and clean soil have been more clearly defined by the recommended soil

investigations, and the appropriate removal requirements established, these parameters will be incorporated into

the development of the project Traffic Management Plan by the Design-Builder. This evolving plan will define

appropriate routes for the movement of material (removal or relocation). This plan will include: the scheduling of

haulage into low traffic times, identified truck routes and anticipated disposal locations. This plan will also include

access management arrangements and sediment/biological controls (wheel washing / cleansing). Other

requirements of the project Traffic Management Plan are included in the Construction Environmental Management

Plan (CEMP) and include access, incident management, communications, and laydown areas.

4.8 Confirmatory Soil Sampling The recommended detailed environmental investigations will inform whether contaminated soil is present within

and/or beyond the project footprints. If possible, all contaminated soil within a planned excavation should be

removed, and this removal should be confirmed by collecting confirmatory soil samples from the excavation limits

per the MOE’s TG-1. Soil samples will be collected in-situ from the base and walls of the excavation every 10

metres horizontally and 1 metre vertically along the base and walls of the excavation. The samples will be

submitted for analysis of the applicable PCOCs or COCs for that APEC or AEC.

If suspected contaminated soil is encountered during an excavation outside of the previously identified AECs or

APECs, the soil will be sampled and analysed under the guidance of an environmental professional.

4.9 Tracking and Record Keeping The DB Contractor will be responsible for the development and implementation of a record keeping system to track

and record the volume and characteristics of contaminated soil. Appropriate documentation of the movement and

disposal of contaminated soil will be followed. The contaminated soil waste soil classification, source location, date

of excavation, estimated tonnage, date of hauling, and receiving facility will be documented. All shipping documents

and delivery receipts will be included as part of the tracking record. If hazardous wastes are identified, then a

hazardous waste generator number and carbon-copy tracking manifests will also be required.

Metro Vancouver




Soil Manifests contain information on the type and quantity of the waste being transported, instructions for handing

the waste and signature lines for all parties involved in the disposal process. Once the waste reaches its

destination, the receiving facility returns a signed copy of the manifest to the generator, confirming the waste has

been received by the designated facility. Soil Manifests will be collected and retained by the DB Contractor and

kept as a permanent record of soil removed from the Site.

4.10 Groundwater Management The scope of this Draft SM Plan includes groundwater management. The water table is relatively high,

approximately two metres below ground surface. The probable maximum construction depth will be down to 15

metres. Groundwater will need to be treated prior to discharge to the environment. The Design Builder will be

responsible for supply and operation of an appropriate treatment system to treat groundwater to acceptable

standards prior to discharge.

Monitoring wells at the Site that no longer serve their intended purpose will be properly decommissioned by the

Design-Builder. Well decommissioning is required to prevent surface infiltration of contaminants to an underlying

aquifer and prevent cross communication between flow zones intercepted by a well screen. The CCME Guidance

Manual for Environmental Site Characterization in Support of Environmental and Human Health Risk Assessment

(CCME, 2016) provides the following guidance on well abandonment:

For wells where the screen and filter pack intervals do not cross communication between separate

groundwater flow zones, the well casing should be removed, if possible. The borehole should be backfilled

from its base with a bentonite grout or cement-bentonite mixture via a tremie pipe.

Alternatively, the well may be sealed by the injection of grout into the well under pressure in order to inject

the grout through the well screen and into the surrounding filter pack. Placement of grout into the well

casing will not address the filter pack of the well.

If a well has been damaged below the ground surface and is not accessible, the well should be over drilled,

with the borehole grouted to surface.

While not directly applicable at the site, the BC Groundwater Protection Regulation also provides guidance on when

and how a well should be decommissioned in BC. The guidance in the Regulation states that if a well is not used

for five years, it should be backfilled with layers of sealant and backfill materials that precludes any lengthwise

movement of liquids. This will be effectively accomplished by following the CCME guidance.

Metro Vancouver




5. Health and Safety

The DB Contractor will be responsible for working with Port to develop a site-specific health and safety plan (HASP)

prior to the start of construction activities. WorkSafeBC Occupational Health and Safety Regulations will apply to

personnel involved in excavation of soil and associated activities. The HASP will include specific processes and

procedures mandatory for all field crews to complete the planned tasks. The HASP will identify the potential site

and activity risks and associated mitigative measures to address those risks. Those risks will specifically include

potential exposure through inhalation, absorption, or ingestion to the soil contaminants listed in Table 3-3, plus any

additional contaminants confirmed on-site.

Detailed Job Safety Analyses (JSAs) for specific field activities will be prepared in advance and appended to the

HASP. Within a JSA specific steps required to complete each field task, the hazards associated with the identified

task and the actions required to eliminate, reduce or mitigate the hazard are identified. The JSA will be thoroughly

reviewed with the field crew prior to the start of each day and updated when conditions change.

Precautionary measures will include adequate personal protective equipment, eliminating or mitigating exposure to

contaminants, excavation and confined space entry procedures, first aid and emergency response procedures,

personnel, and equipment.

5.1 Emergency Response Plan A significant component of a HASP is a site specific Emergency Response Plan (ERP). Components of an ERP

include the following:
