Aquatic Effects Monitoring Program (AEMP) Fish Response Plan, Version 1.2, Ekati Diamond Mine (Dominion Diamond, June 2018)
25 June 2018Report
Dominion Diamond Ekati ULC submits Version 1.2 of the Response Plan for Fish to the Wek'èezhìi Land and Water Board, addressing low action level exceedances for antimony, molybdenum, selenium, uranium, and EROD activity in fish tissue detected in the 2012 Aquatic Effects Monitoring Program. The plan proposes low, medium, and high action levels with rationale for response actions to manage mine-related changes in fish tissue contaminants while maintaining protection of the aquatic receiving environment.

Aquatic Effects Monitoring Program (AEMP) Selenium Response Plan, Version 1.0, Ekati Diamond Mine (Dominion Diamond, August 2016)
31 August 2016Report
Dominion Diamond Ekati Corporation's Aquatic Response Plan for Selenium addresses the exceedance of low action levels for selenium in Cujo Lake detected during 2016 under-ice monitoring, caused by discharge of selenium-elevated water from the King Pond Settling Facility resulting from pumping of Misery Pit and Desperation Pond water in 2015. The plan proposes continued AEMP monitoring and a literature review on selenium toxicology to establish medium and high action levels, with an interim medium action level of 0.0015 mg/L based on US EPA criteria for lentic environments.

Closed Pit Lake Fish Habitat Jurisdictional Motion, WLWB Public Hearing Record, Ekati Diamond Mine (MVLWB, July 2009)
26 July 2009Regulatory Filing
The Wek'èezhii Land and Water Board issued a decision rejecting BHP Billiton's motion claiming the Board lacks jurisdiction to require fish habitat establishment in closed pit lakes at Ekati, ruling that the 1996 Fish Habitat Compensation Agreement does not limit the Board's statutory authority to impose fish habitat reclamation requirements. The Board concluded it has jurisdiction to require fish habitat restoration as part of mine closure and reclamation, whether the Agreement is characterized as a private contract or part of a regulatory authorization.
