Notice of Determination for the Hatchet Lake Nursing Station

The determination was based on a consideration of the following factors:

• the Hatchet Lake Denesuline Nation has authorized the development by Band Council Resolution, and its membership will benefit from the project
• no comments were received from the public about the project
• mitigation measures are required for the project

 Implementation of the following conditions and mitigation measures are required for the project:

1. The project shall proceed in the manner described in the ISC Project Description form,  Johnston, R. (Johnston Projects.), personal communication, DRAFT Hatchet Lake Nursing Station NOD Mitigation Measures (May 2, 2025 and May 28, 2025) and Hatchet Lake First Nation, Primary Care Clinic Site Plan (May 1, 2025).
   • The DRAFT site plan for the Primary Care Clinic, dated May 1, 2025, depicts the clinic building south of the approximate location of the abandoned lagoon cells. The plan indicates a parking lot will be located over the south cell of the abandoned lagoon.
     • The Proponent will immediately notify ISC of any changes to the proposed project for approval.
2. Relevant permits and approvals will be obtained before undertaking any work. It is the Proponent's responsibility to meet all applicable federal, provincial and municipal laws and regulations that apply to the proposed project. This Notice of Determination does not apply to ancillary features associated with this development that were not included in the Project Description form.
3. Limit ground disturbance activities deeper than 6 inches will be completed over and within 20 m of the approximate abandoned lagoon cells boundaries identified within the Site Plan (May 1, 2025). Where ground disturbance or grading activities are greater than 6 inches within this zone are required, submit a plan to ISC Environment, for approval, identifying how the project will ensure the integrity of the abandoned lagoon cap is stable and drainage pathways will not be impacted.
4. No aspect of the occupied spaces of the clinic building will be below grade. All development of these areas will be completed on a cement slab on grade foundation to prevent potential impacts from vapor intrusion and/or groundwater interactions.
5. All work will be carried out in accordance with the Migratory Bird Convention Act and applicable regulations.
6. All water supplied to and removed from the project facility will be delivered through new engineered water utility pipelines.
7. The project design will ensure project drainage is designed to prevent potential interactions with groundwater in proximity to the project location.
8. The project will submit a Soil Management Plan and a Contamination Discovery Plan to ISC, for approval, prior to commencement of construction activities.
   • The Plans will be required to include contingency plans and protocols for incidental discovery of contaminants during construction. This includes potential contaminants or risks associated with the abandoned lagoon, as well as the possibility for contamination from fuel releases or storage tanks, etc. The plan will also be required to include how waste/contaminated material will be managed and disposed of.
9. Waste and/or hazardous materials must be removed from site as soon as practicable and taken to a certified/approved landfill in accordance with provincial and municipal legislation.
10. Careful maintenance and monitoring of all equipment will be carried out to minimize the risk of spills or leaks of petroleum-based products. Storage of hazardous material and refueling is prohibited within 100 m of a water body. The contractor will have an emergency response plan to manage fuel spills.
11. Regardless of volume, any spilled substance that may cause an adverse effect must be cleaned up immediately and contaminated materials removed from the site for proper disposal. All spills must be reported to relevant federal, provincial and municipal government departments.
12. Dust control must be implemented to prevent air quality impacts and ensure the safety of nearby public.
13. All equipment must be properly maintained and equipped with standard air emissions equipment.

Indigenous Services Canada is satisfied that the carrying out of the project is not likely to cause significant adverse environmental effects.
