Feasibility level design of physical restoration alternatives were conducted to restore the natural resources of the Blackbird Mine site to baseline conditions.
The major sources of acid mine drainage are waste rock, tailings, and mine portal discharges. Bucktail Creek and Blackbird Creek drain the mine site and are tributaries of Panther Creek, which in turn flows to the Salmon River. Historical records indicate that prior to the 1950’s; Panther Creek was a trout and salmon fishery. Current fishery assessments revealed that the number of trout has declined and no salmon are present.
Deere & Ault Consultants, Inc. (D&A) personnel participated in a physical restoration analysis under Section 107 of CERCLA, providing expert witness testimony in Federal Court. Work included interpretation of historical data, negotiations with potentially responsible parties, preparation of site restoration analysis reports, surface water and groundwater sampling, and sediment sampling.
The case was settled out of Court. The Defendants are currently implementing clean-up of the site.
