Environment and Climate Change Canada (ECCC) is proposing to decommission surplus infrastructure at the Eureka High Arctic Weather Station (HAWS). The HAWS is located on the north side of Slidre Fjord, at the northwestern tip of Fosheim Peninsula, Ellesmere Island, Nunavut. The closest community to HAWS is the Hamlet of Grise Fiord.The project includes the demolition of various structures and infrastructure, the building of a temporary camp to house the workers needed for the demolition, an amendment/extension of the existing water license as well as an extension of the existing quarry permit. Building DemolitionThe Building Demolition includes the demolition of various structures and infrastructure, including the Former Main Complex, Red Quonset, Building 12, Abandoned Reefer, Carpentry/Plumbing Shop, Former Plumbing Building water storage tank (building burnt down in 2019), original Quonset/Storage Shed, Storage Shed, Greenhouse, Old Transient Barracks, former Bunk House and abandoned electrical poles. These buildings and infrastructure are no longer used due to them being abandoned, obsolete, old and/or in disrepair. It is anticipated that all clean, uncontaminated wood waste will be burned on site and all remaining non-hazardous building demolition waste will be stored and disposed on site in a non-hazardous disposal facility. Hazardous waste will be appropriately packed and shipped offsite. The timing of the Building Demolition is scheduled to take place from July 2021 to October 2024.The following plans will be prepared prior to construction start: Environmental Protection Plan, Health and Safety Plan, Emergency Response Plan, Erosion, Sediment and Drainage Control Plan, Spill Contingency Plan, Fire Safety Plan, Worker Orientation Seminar, Building Deconstruction/Decontamination Plan, and Waste Management Plan. The Wildlife and Wildlife Habitat Management Plan that has been developed for Eureka HAWS (SLR, 2018) will also be followed by all onsite personnel. Temporary CampA Temporary Camp for approximately twenty staff will be required for this project. This camp will be installed in a way that will minimize impacts to the environment and will be removed upon completion of the Building Demolition work. Camp facilities will include power generators, fuel storage facilities, garbage disposal containers, heating and cooling units, and necessary appliances and furniture.Amendment/Extension of Water LicenceAs part of this project, an Amendment and Extension of the current Water Licence No. 8B-EUR1621 (Water Licence) is required. An amendment is requested to include water and waste activities associated with the Building Demolition and Temporary Camp. The Water Licence is due to expire August 10, 2021 and so also requires an extension so that current operational water and waste activities can continue at Eureka HAWS.Extension of Quarry PermitQuarrying Permit 2018QP0001 is due to expire on June 17, 2021 and requires an extension so that current quarrying activities can continue at Eureka HAWS.
