Section 2. PROJECT DESCRIPTION REQUIREMENTS

2.1 GENERAL SCOPE

The electrical system of the Cargill grain handling terminal, located at 801 Low Level Road, North Vancouver, dates back to 1960s when the original Saskatchewan Wheat Pool terminal was built. Major pieces of power equipment, such as the incoming 69kV oil circuit breaker, step-down power transformers, 600V distribution switchgear, etc., are nearing the end of their life. There is also a growing concern that the original 600V cable connections made out of mineral-insulated cables may start failing in the near future.

The power system upgrade project will see that both the 69kV and some of the old 600V equipment is replaced with new equipment, and will introduce a new 12.47kV voltage level to optimize power distribution throughout the terminal by reducing electrical losses associated with higher currents at lower voltages.

It is proposed to construct a new indoor 69kV substation (hereinafter Substation) to the east of Cargill's Annex 2 elevator building (see Appendix A and Appendix B for the location and site plan drawings), which will accept a new 69kV transmission tap connection from the existing BC Hydro's line 60L062SWP, and house a 72.5kV gas-insulated switchgear (GIS) line-up, two environmentally-friendly-liquid-insulated 7.5/10MVA power transformers, and one 15kV-class arc-resistant switchgear line-up.

The new 600V and 12.47kV equipment will be organized into four unit substations (hereinafter Unit Substations 1–4) located within the plant in two existing electrical rooms (Unit Substations 1 and 3/4) and one newly built room (Unit Substation 2). The existing electrical rooms will be upgraded to be code-compliant, and the new room will be built according to the latest applicable codes.

The Substation will be connected to the Unit Substations by means of a multi-cable duct bank and a system of cable trays along the south wall of Annex 2 as shown in the location plan drawing A1-15019-C002 (see Appendix A). The Unit Substations will feed the existing Motor Control Centers (MCCs) located in various electrical rooms within the plant by means of new cable connections that will replace the mineral-insulated cables.

The project will also include decommissioning and dismantling of the existing 69kV switchyard currently feeding the terminal as well as parts of the electrical system that will not be re-used, such as the existing oil-filled power transformers, 600V distribution gear, cables, etc. (see Section 2.3.4 and Appendices C, D & E for demolition details).

2.2 OPERATIONS

No adverse impacts to the environment or the communities in the vicinity of the project area are anticipated during normal operations as all of the new electrical equipment other than the power transformers will be enclosed. The transformers will be facing south (Burrard inlet) and will be effectively shielded by their roof and the Substation building.

Gas-insulated (inert SF6 gas, see Appendix F for MSDS) and dry-type electrical equipment shall operate trouble-free and pose no concerns to the environment or the communities nearby.

Insulating-liquid-filled power transformers will be installed in concrete containments filled with gravel and intended to collect all insulating liquid from each transformer with an additional layer to inhibit any open fire. The project intends to use the vegetable-oil-based environmentally-friendly and high-fire-point FR3 insulating liquid as the FM Global approved insulating and cooling medium (see Appendix G for MSDS). A concrete roof above the transformers will prevent any precipitation from entering into the containments, rendering any sewer drainage connection and oil interceptors unnecessary.

Minimizing the disturbances to the local residences is of vital importance to Cargill and Port Metro Vancouver. During working hours PCL will work within the regulations set out in the noise bylaw. Any afterhours work will be submitted for approval to the PMV prior to starting the work to provide adequate notification to residents (refer to Section 5.1).

Detailed Spill Contingency and Construction Waste Management Plans will be utilized by PCL and any subcontractors on site (refer to Appendix C & Appendix D). Strict adherence to these plans will be enforced.



2.3 CONSTRUCTION & DEMOLITION

2.3.1 Timeline and Working Hours

The project is currently scheduled to run from February 20th 2017 to August 18th 2018, 7am to 3:30pm Monday to Friday. No work during weekends or statutory holidays is anticipated at the start of the project unless is required by a construction process (e.g. concrete works), of which PMV will be notified accordingly.

2.3.2 Traffic Management and Maintenance

PCL will provide traffic management to assist trucks entering or leaving the site as required, re-routing of traffic during partial road closures, and to escort the Zoom Boom between the laydown and the hoisting locations.

During ground densification a route will be provided for emergency vehicle access. There will be two routes for vehicle access depending on the stage of the ground densification. Signage will be posted indicating traffic routing. The plan will be broken into two phases shown in Figure 1 and Figure 2 below:

Figure 1: Phase 1 – Traffic Routing for Substation Densification

Figure 2: Phase 2 – Traffic Routing for Substation Densification



2.3.3 Temporary Facilities

2.3.3.1 SITE OFFICE

A site office complex will be set up consisting of an office trailer, lunch room trailers, wheel wash station, and first aid trailer.

2.3.3.2 SECURITY

The laydown and sub-station work area will be fenced with Moduloc fencing. Gates will be provided around the area to allow for access.

2.3.3.3 TEMPORARY POWER AND LIGHTING

Temporary power is not required within the terminal facility. Most work will be carried out utilizing air equipment connected to owner’s air distribution system. Temporary power will be required with the new main sub-station building. C-panels will be set up to provide power for tools and equipment.

Temporary lighting will not be required within the terminal. Temporary lighting will be required for exterior work and extended hours work outside of the terminal building. This work will include the main sub-station building, duct bank, and cable tray installation.

Special note: The work area inside of the terminal is a high hazard environment due to the possible presence of explosive grain dust. NO tools, extension cords, lights or other devices that could create a spark are permitted without the written consent of the terminal manager and the Project Superintendent.

2.3.3.4 FIRE PROTECTION

PCL will provide fire extinguishers throughout the site as identified on the site plan, at exterior locations only. There is no firefighting permitted within the facility.

Fire truck access will be maintained at all times during construction. Cargill Emergency Evacuation Procedures will be followed by all personnel working on the project.

Detailed Spill Contingency and Construction Waste Management Plans given in Appendix C & Appendix D provide further details on mitigation strategies in addition to those listed above in Table 2.

Prior to demolition work BC Hydro and Telus utilities will either be disconnected (BC Hydro 69kV transmission line) or re-routed (Telus communication lines). Both utilities will be properly notified in advance of any planned work.

2.3.5 Electrical Planning

Three different crews will be used to complete the electrical work:

Crew 1 – PDC Rooms

Crew 2 – Ductbank and Cable Tray Feeds

Crew 3 – Substation Building

The electrical contractor will connect the owner supplied equipment once it is delivered to site (see Section 2.3.6 for material handling plan for hoisting of the equipment). New feeds will be run from the new Unit Substation equipment (Unit Substations 1 – 4) to the existing sixteen MCC rooms. Some of these existing feeds will be re-used where possible. The main feeds will also be run from the Substation equipment to the new Unit Substation equipment. This will be pulled via a ductbank below the Cargill Access Road and up to a cable tray mounted to the south side of Annex 2.

One new transmission pole will be installed in line with the existing 69kV line 60L062SWP on the north side of the CN tracks. A single 69kV transmission span will cross both the CN and Cargill-owned tracks from that pole to terminate on a new pole installed next to the Substation. Once the Substation is energized, it will run all of the four new Unit Substations and the Ship Loader.

Once the new equipment is energized, the existing switchyard SWP will be decommissioned.

The Substation and 69kV Tap will only be energized upon obtaining a signoff from BC Hydro and the City of North Vancouver's electrical inspector. Details on the signoff process are provided in BC Hydro's Operating Order 1T-35, "Commissioning Procedure for Generators, Station and Transmission Projects" given in Appendix I. The Cargill's



facility falls under the Transmission Voltage Customer (TVC) category; therefore the following documentation is required to be submitted to and approved by BC Hydro prior to the energization:

1. Declaration of Compatibility forms (TVC Substation Load and Transmission Line Facilities) signed by a Professional Engineer on behalf of the Customer and provided to BC Hydro.

2. Commissioning Notice to Energize (if required). 3. Revised Operating Order and Revised Operating One-Line diagrams. 4. Revised Alarm Operating Orders (if required). 5. Revised Protection Information Sheets (if required). 6. Initial energization sequence, including any operating restrictions.

2.3.6 Material Handling Systems

2.3.6.1 MATERIAL AND EQUIPMENT STORAGE

Storage

Materials and equipment will be stored in the fenced PCL laydown area and storage areas as shown on the jobsite plot plan. Storage areas must be kept neat at all times. There will be a designated and contained area for fuel storage in the laydown area. The laydown area will include lock block containment for new/reused soil and any contaminated soil.

2.3.6.2 MATERIAL AND EQUIPMENT HANDLING PROCEDURES

Mobile Cranes

Mobile cranes will be used periodically at three locations throughout the project when the hoist beams are insufficient. A crane company will be used to hoist material using the approved hoisting locations.

Prior to using a mobile crane on this project the details must be reviewed and approved by PCL. All critical and engineered lifts must be reviewed and approved by PCL prior to lift taking place.

Owner Supplied Equipment

PCL will receive the owner’s equipment on site. A subcontractor will be brought in to install the equipment into its final location. PCL will work with Cargill to determine hoisting areas on site. Approx. hoisting areas have been noted on the site plan at this time and are subject to change.

2.3.6.3 DELIVERIES

All deliveries should occur during regular work hours and have to be scheduled with the PCL Superintendent.

2.3.6.4 CONCRETE DELIVERY

Concrete delivery will be along the roadway leading to the breezeway and using Cargill’s established truck turnaround. Staging of trucks and/or concrete pumps must be coordinated and approved by Cargill. Concrete work will be on the south and east sides of the terminal. All concrete trucks and pumps will be washed out offsite to eliminate the potential for ground contamination.



Section 3. DRAWING REQUIREMENTS

3.1 LOCATION PLAN

See Appendix A for drawing A1-15019-C002 showing the location of the project site relative to its surroundings at a 1:5000 scale with detail views showing Work Areas 1 through 7.

3.2 SITE PLAN

See Appendix B for the site plan drawing A-01 prepared by the Chernoff Thompson Architects (CTA).

3.3 BUILDINGS, STRUCTURES & EQUIPMENT

See Appendix J for the Building & Equipment drawings.

3.4 UTILITIES

The project requires two types of utility connections:

Overhead electricity supply at 69kV, provided by BC Hydro, and

Underground storm sewer service.

3.4.1 69kV Overhead Electricity Supply

BC Hydro has been approached to facilitate the new electricity connection at 69kV and subsequently provided a System Impact Study and Scope Notes documents, as given in Appendix K. At this point in time, it is anticipated that Cargill will be responsible for the design, construction, operation and maintenance of the 69kV tap, whereas BC Hydro would be responsible for design checks and regulatory work (First Nations, environmental, due diligence, etc.).

3.4.2 Underground Sewer Utility

As mentioned in Section 2.2 above, no sanitary sewer connection is required for the substation transformers' containments as those are covered. A storm sewer connection is required for the Substation building to properly divert precipitation from the structure.

The City of North Vancouver (CNV), Metro Vancouver and Neptune Bulk Terminals (NBT) were contacted to determine if they owned the utilities Cargill's existing storm sewer is connected to. Based on feedback from NBT, Cargill is deemed to be connected to a sewer pipe owned by NBT, while the latter is connected to the CNV's system. This, however, is disputed by CNV, who maintains that Port leased land is not serviced by the City. Metro Vancouver verbally advised that they did not own any sewerage in the immediate vicinity of Cargill. The relevant correspondence is attached in Appendix L. As can be seen from the correspondence, neither NBT nor CNV object Cargill connecting the building drainage to a storm sewer.

Cargill also has an independent storm sewer equipped with catchment basins that outfalls into the Burrard inlet, which may be used for non-hazardous drainage such as the Substation building.

Drawing A1-15019-C005 in Appendix M shows the proposed utility connections as well as underground utilities not used by the project. For rail crossing details see Section 3.7 below.

3.5 LIGHTING PLAN

The project is planning to use LED lighting fixtures similar to those attached in Appendix N. These lights have been used in numerous infrastructural projects in the Lower Mainland, including port installations (Westshore terminals, Seaspan, Viterra and Neptune Bulk Terminals). The manufacturer is a member of BC Hydro's Alliance of Energy Professionals.

The immediate surroundings of the Substation building along with the nearby lighting to be installed as part of the Cargill's Track Expansion Project, have been modeled to evaluate the lighting levels in the area to be developed. Drawing A1-15019-L001 in Appendix O shows the illuminance levels in lux in the vicinity of the building, which



are in compliance with WorkSafeBC regulations (available at https://www.worksafebc.com/en/law-policy/occupational-health-safety/searchable-ohs-regulation/ohs-regulation/part-04-general-conditions#SectionNumber:4.65) and Canada Occupational Health and Safety Regulations (available at http://laws.justice.gc.ca/PDF/SOR-86-304.pdf).

3.6 PARKING & ACCESS

The proposed 69kV Substation building is an unmanned facility intended to operate autonomously with only occasional visits by Cargill's personnel. Therefore, no additional parking stalls are required in close proximity of the building.

New fire access and maintenance roads are planned to the east and north of the Substation as shown in drawing A-01 in Appendix B. The fire access roads and the turning radii have been approved by the City of North Vancouver (correspondence attached in Appendix P).

3.7 RAIL

An application was put through to CN Railways to obtain a permission to cross their tracks in the vicinity of the Substation. The permission was granted subject to building the 69kV tap according to drawing A1-15019-T001 provided in Appendix Q. A letter from the Utilities Coordinator is also attached.

Section 4. REQUIRED STUDIES AND REPORTS

4.1 HAZARDOUS MATERIALS REPORT FOR DEMOLITIONS

Two contractors have been retained to perform site investigations within and around the grain terminal:

1. Pinchin West Ltd. (Pinchin) – responsible for hazardous materials assessment in the existing electrical rooms to be modified and the 69kV switchyard to be demolished.

2. Thurber Engineering Ltd. (Thurber) – responsible for soil contaminant assessment around the terminal buildings and structures.

According to Pinchin's report (see Appendix R), the following hazardous materials were found to be present in the plant:

Asbestos

Lead

Silica

A summary of recommendations has been provided to address each of these materials in the report. A Hazardous Materials Field Survey Report Form filled out by Pinchin is also attached in Appendix R.

Thurber performed soil sampling at eight locations shown in their report attached in Appendix S. Light Extractable Petroleum Hydrocarbon (LEPH) exceedance was identified at one location (borehole 16-3), likely related to minor leaks and spills from the fuel storage area nearby. A recommendation is made to transport any soil in the vicinity of borehole 16-3 to an approved facility should it be excavated and required to be disposed of.

In addition to the above, oil samples were taken by Magna IV Engineering from the oil-filled transformers and the 69kV oil circuit breaker to verify any PCB contamination of the equipment insulating oil (report attached in Appendix T). It was found that the two main power transformers have PCB levels of 3.0 and 4.6ppm, which exceed the Environment Canada's regulatory limit of 2ppm for releasing into environment (see PCB Regulations document available at http://laws-lois.justice.gc.ca/PDF/SOR-2008-273.pdf) but are below the regulatory threshold of 50ppm. Consequently, neither Transport Canada nor Department of Justice regulations are applicable to transporting the PCB-contaminated equipment, however a transport license and manifest forms shall still be obtained from the province of BC to transport any hazardous waste for quantities in excess of those published by the government of BC (available at http://www2.gov.bc.ca/gov/content/environment/waste-management/hazardous-waste/transporting-hazardous-waste).

Table 3 below summarizes applicable regulations to be followed by construction/demolition contractors, transportation companies and disposal facilities dealing with hazardous materials:

4.6.4 Environmental Incident Reporting

There are two types of environmental incident categories:

Incidents which are not in compliance with legislation and which must be reported to a regulatory agency, and;

Incidents which are not serious in nature but which have a serious hazard potential and are reported within the company only.

Serious or potentially serious environmental incidents will be investigated by the PCL Superintendent and the on-site Environmental designate in liaison with the District HSE Manager.

Where serious incidents require the services of consultants, expert personnel, or special agencies, arrangements are to be made in consultation with the HSE Director, or the HSE Vice President, NAHQ (for Canadian operations).

4.6.5 Spill Response Plan

Spills of chemical, fuels, and other substances may occur as isolated events or they may occur in association with other emergencies such as fire, explosion, natural causes, or accident.

There are six distinct steps:

Communicate event

Spill details

Control of scene

Spill containment kit retrieval

Spill/release clean up

Disposal of contaminated materials

See Appendix C for Spill Contingency Plan

4.6.6 Communication System

An effective communications system is set up so that key personnel such as the project environmental designate, superintendent, project manager, district manager, and the district HSE manager can be contacted in a timely manner. This system includes public agencies such as government environmental agencies, and emergency services if required.

4.6.7 Spill Details

When a spill occurs, the person discovering the spill must provide details of the spill such as:

Location

Product name of spilled substance (if known)

Estimated volume or how much was spilled

Total quantity involved (this refers to potential of additional spillage)

Source of the spill or leak

Any hazards involved

Size of area affected by spill, and

Injuries or personnel requiring medical attention or rescue.

4.6.8 Control of Scene (Affected Area)

When a spill occurs, the designated first responders will evaluate the situation and hazard's before proceeding.

Items to be considered are:

Proper identification of spilled product or substance;

Review MSDS for allocation of appropriate personal protective equipment and other control measures;

Weather conditions which could affect contaminated area such as rain, snow, wind and temperature;

Evacuation of area to protect personnel (if required);

Cordoning off and securing of the contaminated area;



Equipment/materials required to control spill area;

Personal protective equipment required to protect personnel as identified on the MSDS;

Containment to minimize contaminated area;

Extinguish or remove sources of ignition;

Stopping leak or spill at source, i.e. repairing a leaking drum or container, turn off valves, or shut down compressor or pump;

Placing dams of absorption materials to protect sensitive watershed areas such as floor drains, area drains for surface moisture collection, open recessed drains, spillways or watershed avenues; and

Taking photographs of contaminated and affected area(s).

4.6.9 Spill Station / Spill Containment Kit

Obtain spill response kit from its identified location on the site safety plan;

Obtain MSDS for product spilled (if known) so that the correct response/clean up can be accomplished in a timely manner;

Collect any Personal protective equipment required that is identified on the MSDS

Shovels, pails, plastic bags, over pack barrel(s);

Neutralizers;

Labels for each containment of hazardous waste, identify date, Contractor and material/contaminant;

Log for contaminated waste. Including; No. of bags, Contractor and material/contaminant.

4.6.10 Clean-Up Operations

Clean up operations will be dictated by the situation and circumstances but generally consist of:

Extraction and transfer of spilled material/substance into tanks or barrels;

Extraction and transfer of contaminated soil, material or water into tanks or drums;

Placement of damaged drums or containers into over packs;

Extraction and transfer of used absorbents into drums;

Placement of labels on drums, tanks and over packs; and

Proper storage and transfer of materials or substances.

4.6.11 Storage / Transfer and Disposal of Hazardous Waste

The Hazardous Materials Storage area for this project is in the laydown area next to the sea-cans as shown on the site plot plan. This area must store (and is not limited to) all hazardous materials associated with the project such as Diesel Fuel, Gasoline, Form Oils, Lubricating Oils, Propane Cylinders, Acetylene Cylinders, Glycol and other environmentally damaging substances. This area will be clearly identified through the use of signage.

Transfer and disposal of hazardous waste will be conducted as per jurisdictional legislated requirements and only by a licensed hauler/disposal agency with properly trained employees.

4.7 SOIL MANAGEMENT PLAN

This includes removal of existing asphalt, densification of the existing ground conditions, excavations for the raft slab and duct bank, new civil services, and new asphalt w/ line painting.

Densification is required below the Substation building to increase the strength of the ground conditions. To achieve this stone columns will be installed by wet top-feed vibro replacement methods. Pre-drilling to the stone column locations will be completed where native soils need to be loosened prior to installation of the stone columns. Water supply will be required to install the stone columns but water quantities will be kept to an absolute minimum in order to minimize subsequent water control, spoil generation and disposal requirements. In the event of excess water a berm will be built to contain the water to a generalized area.

The excavations for the raft slab and duct bank will be approx. 12ft deep and 6ft respectively, and sloped at a minimum of 3:1 (H:V) unless approved by a qualified registered professional.

Soil will be tested prior to the start of the work to ensure that it is uncontaminated. Contractors will monitor the excavated soils on an on-going basis to observe visual and olfactory indicators of contamination.



Non-suspect soil that is excavated will be used for backfill and grading within the same legal parcel where it originated. If this material cannot be re-used on site it will be tested to ensure that it can be transported off-site to a fill location. In the event that excavated soil is suspected to be contaminated the soil will be isolated to a secured location and an environmental monitor will be notified. The EM will provide further direction once they have completed their review of the soil.

From previous work on the Cargill site we expect very little to no soil contamination and found we were able to re-use most of the soil on the site. Refer to Appendix S for performed soil contamination test reports.
