Environment and Climate Change Canada (ECCC) is proposing to expand the existing quarry located at West Remus Creek. The expansion is required because additional aggregate is required for use at the Eureka High Arctic Weather Station (HAWS) beyond the capacity of the current established quarry. 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 the HAWS is the Hamlet of Grise Fiord.The project includes geotechnical surveys to determine the area of an expansion, an archeological assessment of the expansion area and the expansion of the quarry itself once it has been selected based on the results of the geotechnical survey and archeological assessment. The timing is scheduled to take place from 2021 to 2025 where construction is anticipated to occur in June 2021 and operations are to occur between July 2021 and October 2025. During construction, approximately 50 site personnel are required. Transportation to site will be through the use of chartered aircraft for personnel, food and smaller supplies and sealift for equipment and larger supplies.Quarry ExpansionAdditional aggregate, estimated at 175,000m3, a portion of which is contingency, is required to support project activities at the Eureka High Arctic Weather Station (HAWS). Therefore, an expansion of the quarry at West Remus Creek is needed as the additional aggregate required is not available within the current permitted boundaries. There are three areas proposed for expansion; the primary expansion area which is immediately east of the quarry and north Remus Creek; two others are east of the quarry and south of Remus Creek. The two proposed expansion areas to the south are contingency areas in the case that acceptable aggregate grade is not available in the primary expansion area. To access these areas, vehicles will need to cross Remus Creek and West Remus Creek. A request for review has been submitted to the Department of Fisheries and Oceans which proposes the construction of two temporary culvert stream crossings. These crossings are proposed to ensure vehicles cross these two waterbodies with minimal impacts to the environment. It is recognized that the proposed expansion areas are large relative to the existing boundaries of the current quarry. This is because sufficient geotechnical data is not available at this time to determine the exact optimal supply areas. Geotechnical surveys are planned to commence spring/summer this year to determine their location and it is only these areas that will extracted. Furthermore, an archaeological assessment will be completed for the entire expansion area in spring 2021 in conjunction with the geotechnical investigations. If any archaeological areas of significance are identified, they will be protected through mitigation measures approved by the Nunavut Department of Culture and Heritage. Mitigation may include fencing around sensitive areas and applying setbacks. Previous archaeological studies of the general area were conducted in 2018. A permit to conduct the archaeological assessment will be requested from the Nunavut Department of Culture and Heritage prior to March 31st, 2021. Any work/project activities and travel will follow all Territorial and Federal requirements and guidelines regarding COVID 19.
