Reed Mine and Upper Davis Creek Remediation Project

MND - Mitigated Negative Declaration

Document Description
Homestake Mining Company has proposed the Reed Mine and Upper Davis Creek Remediation Project on lands owned by Homestake. The goal of the project is to clean up and abate the Reed Mine mercury mining wastes to minimize further erosion and impact to surface waters along the Upper Davis Creek. The project would meet these goals by removing mine waste (waste rock and tailings) located near surface water along Upper Davis Creek and consolidating it in an onsite repository. Mining waste located further away from surface water is proposed to be stabilized in place. Mine drainage seep is proposed to be treated by semi-passive treatment. Additionally, the project would protect human health and the environment by removing process residuals that contain elevated levels of mercury and disposing them at a permitted offsite repository.
