Qulliq Energy Corporation (QEC) Sanikiluaq District Heating System (DHS) (149280)
Proposal Status: Conformity Determination Issued
Project Overview
Type of application: New
Proponent name: Megan Larose
Company: Qulliq Energy Corporation
Start Date: 2020-10-31
End Date: 2060-12-31
Operation Type: Annual
Project Description:
The project includes three components, a heat recovery system located at the power plant, energy transfer stations located within each building being served and a distribution piping system from the power plant to each building to circulate heat transfer fluid through the system. The district heating system in Sanikiluaq would service the Paatsaali School and the Nuiyak School. This will require the installation of two crosslinked polyethylene (PEX) pipelines, approximately 300 metres in length, to connect the buildings with the power plant (Refer to Project Map). Two pipelines will be placed within the same trench, one delivering the heat transfer fluid to the buildings and one returning the fluid back to the power plant for re-heating. The trench will be insulated with a high density soil insulation. The size of the pipelines will be determined as part of detailed design; however, it is estimated that each PEX pipeline will be approximately 4-inches in nominal diameter. The preliminary design indicates ground conditions are conducive for construction of an underground pipeline (i.e., trenching) given the limited presence of permafrost. This will be confirmed along with the routing during final design which is anticipated to occur in early 2020. Construction is tentatively scheduled for summer/fall 2020 after sealift. Depending on weather, local ground conditions, delivery of construction materials and contractor availability, it is anticipated that construction will require approximately three months. The exact number of personnel required during construction will be determined by the contractor; however, it is estimated that approximately three (3) to five (5) people would be employed over the course of the construction phase. The DHS is expected to remain operational for the life of the power plant, with minor maintenance or equipment upgrades over time to keep equipment in good working order. During operation, monitoring programs will be implemented to track pressure changes within the pipeline system. If pressure changes are detected within the system, QEC employees will be notified to investigate the issue. QEC also has a spill response plan and community specific emergency plan that would be implemented in the event of a spill or leak. No new QEC employees will be hired as a result of this Project. Sanikiluaq is not currently included under a land use plan and the Project will take place entirely within the boundaries of the municipality.

Waste Management
Waste Type Quantity Generated Treatement Method Disposal Method
Hazardous waste Waste propylene glycol solution (non hazardous) will be stored in drums/totes within secondary containment and shipped south for disposal at an approved facility
Non-Combustible wastes Construction waste (e.g., pallets, pipe reels, unused pipe) will be disposed in the local landfill only if permitted. Alternatively, construction waste will be removed from site and disposed of at an approved facility.
Hazardous waste In the event of a leak from construction equipment, contaminated soil will be collected and shipped south for disposal
