Clark Fork Coalition v. Dep't of Envtl. QualityAnnotate this Case
Plaintiffs, in anticipation of Revett Silver Company and RC Resources, Inc. (collectively, "Revett") seeking approval for mine-related construction under a general permit, filed this action against the Department of Environmental Quality (DEQ) seeking a declaratory judgment that use of general permits to approve stormwater runoff from the Rock Creek Mine would violate Mont. Admin. R. 17.30.1341(4)(e) because Rock Creek is an area of "unique ecological significance" based on considerations of impacts on fishery resource and local conditions at proposed discharge. The district court granted summary judgment to Plaintiffs and declared the general permit void. The Supreme Court affirmed, holding that DEQ's approval of the use of the general permit to allow storm water discharges was arbitrary and capricious because DEQ failed to consider the relevant factors set forth in the law prior to its decision, and as a result, committed a clear error of judgment.
