1.6 SNC-Lavalin’s Environmental Policy As a global engineering and construction firm, we will always operate in accordance with our four core values of safety, integrity, collaboration and innovation. We collectively commit to protect our people, our stakeholders and the environment from harm. Our commitments › Contribute to the health and wellbeing of our workforce. › Drive a robust safety culture to prevent injuries and to protect our people. › Protect the environment by implementing effective systems and pollution prevention practices. Our principles › Demonstrate visible safety leadership which will set the tone for all our operations. › Comply with all customer requirements, company systems, applicable laws and regulations. › Consult our people and encourage them to participate regularly in HSE activities. › Train and support our people and stakeholders to work in a safe and responsible manner. › Identify, assess and manage all hazards and associated risk levels prior to commencing work. › Require all relevant stakeholders to manage HSE with standards and practices that align with ours. › Drive continuous improvement by establishing objectives and regularly analyzing our performance. While the President and Chief Executive Officer is ultimately responsible for HSE, all employees and stakeholders must share in the application of this policy. By empowering everyone to speak up and act, we will ensure this policy is fully met. 1.7 Site and Project Description The Site is located in the Kam Lake Industrial Park area, which has discretionary residential land use, in the southern portion of the City of Yellowknife. Curry Drive is located to the southwest, and forested land is located to the north, northeast and southeast of the Site. Kam Lake is located approximately 30 m north and east of the Site, and the area generally slopes down towards Kam Lake. The Site consists of two lots: Lot 6 (the southern lot) and Lot 7 (the northern lot). The Site currently consists of a Bulk (petroleum product storage facility) and Cardlock facility (commercial fueling facility). We also plan to work on the neighbouring properties at 13 Coronation Drive (Lot 28, Block 502, Plan 900) and 15 Coronation Drive (Lot 40, Block 502, Plan 4016) pending access agreements with the owners. The scope of work consists of drilling five boreholes to depths of approximately 13 m to 20 m below grade and installing groundwater monitoring wells in each borehole. These wells will assess groundwater conditions at and near the Site. Two previously installed groundwater monitoring wells that are no longer in use will also be decommissioned.

3 Action Plan 3.1 Potential Spill Sizes and Sources There will be no hazardous materials stored at the Site for the drilling activities work but we will have onsite equipment including drill rigs, heavy equipment and vehicles that could result in spills and leaks. Table 1 below has a list of potential discharge events that could occur at the Site and a worst-case scenario. Risk of a large release is low.

3.2 Procedures

3.2.1 Procedures for Initial Actions In case of a spill, the following steps will be taken in the following order of priority: › As soon as the incident is noticed, stop the work; › Safeguard health and safety: - Ensure that all personnel are accounted for, taking an account of any injuries; - Notify and obtain assistance from emergency responders or outside resources as appropriate for rescue and treatment of injuries; - Survey the scene to ensure safe entry into the area to deal with the spill; and - Assess the corrective course of action and wear appropriate personal protective equipment prior to dealing with the spill. › Preserve property; and › Reduce environmental impact. The tasks under property preservation and reduction of environment impact are related and are as follows: › Eliminate all ignition sources; › Identify source of leak and determine corrective actions; › Implement corrective actions to try to stop the leak at the source; › If leak cannot be controlled, employ spill containment, which may include directing the leak into a temporary container, use of absorbent material to contain the liquid, preventing the liquid from reaching Kam Lake by constructing a temporary dyke, etc.; › Cover the affected area with a tarp if there are chances of rain; › Spills onto the ground will be collected and disposed of appropriately off-site; › Site Supervisor or delegate to notify Project Manager as soon as initial emergency response is complete and site is safe; › Project Manager to advise governmental agencies as per regulation; and › Site Supervisor to begin collecting relevant information and statements required for incident investigation (e.g. who, what, where, and when). Take pictures of the scene. 3.2.2 Spill Reporting Procedures Report spills immediately to the project manager who will determine if the spill is to be reported to the Northwest Territories (NWT) 24-Hour Spill Line at 1-867-920-8130 ([email protected]) and other authorities that may include the Workers’ Safety and Compensation Commission (WSCC), the City of Yellowknife and the client. Appendix 1 has a list of the quantities for spills in the NWT that must be reported. The on-Site project H&S binder, as well as the project manager, will have copies of the NWT Spill Report form (see Appendix 2).

3.2.3 Procedures for Containing and Controlling the Spill This section outlines the procedures to quickly contain the spill on land and water.

3.2.3.1 Containment of Spills on Land If the spill involves liquids, it is important that the spill does not reach open water bodies. Employ spill containment which includes use of absorbent material to collect the liquid. If possible direct the leak into a temporary container. Prevent the liquid from reaching Kam Lake by constructing a temporary dyke to limit the spread (using soil, booms or absorbent pads).

3.2.3.2 Containment of Spills on Water For spills in the water body, which is not expected for this work, booms should be deployed right away to contain the spill. They should be released from the shore of the water body to create a circle around the spill. 3.2.4 Procedures for Transferring, Storing, and Managing Spill-related Wastes Waste (spilled product/lubricants, contaminated soil, absorbents) that is generated due to the spill will be placed into drums and sealed for proper disposal at an appropriately permitted facility. 3.2.5 Procedures for Restoring Affected Areas Once the reportable spill has been contained and necessary notifications have been made, SNC- Lavalin will be in contact with the Indian and Northern Affairs Canada (INAC) or lead agency inspector to determine the required level of cleanup and restoration for the Site.

5 Spill Response Training Program

All individuals entering the Site are required to participate in a health and safety orientation session. During this session, the spill plan and all locations of the spill kits will be provided. All members of the work team shall be trained in the use of spill containment equipment/items. During the meeting the team will address all the materials that could be spilled. All employees and contractors are required to have Workplace Hazardous Materials Information System (WHMIS) training and a worker with Level 1 first aid training will be designated as the First Aid attendant. Supervisors and subcontractors will also have Transportation of Dangerous Goods (TDG) training. The Site supervisor will have all training documentation on Site with them.
