Aquatic Effects Monitoring Program (AEMP) Re-evaluation 2022, Appendices, Ekati Diamond Mine (Arctic Canadian Diamond Company, December 2022)
This document presents the 2022 Aquatic Response Framework (ARF) re-evaluation for the Ekati Diamond Mine, incorporating lessons learned since 2015 implementation and addressing regulatory directives. It proposes six recommendations including adding total iron and removing total vanadium from water quality variables, updating action levels for biological variables to require mine-related effect conclusions, and clarifying response procedures when action level exceedances are not mine-related.
