| Abstract |
An evaluation was conducted to determine wastewater permit limitations under the National Pollutant Discharge Elimination System (NPDES) for the Homestake Mining Company in South Dakota. EPA also determined whether the Lead-Deadwood Sanitary District could handle the Company wastewater effluent. Fish bioassay tests were conducted on wastewater effluents from both facilities. Analyses of bioassay results and supporting chemical data led to the conclusion that cyanide was the principal toxic agent. In order to establish a cold water fishery of Whitewood creek (the receiving stream), it was concluded that the total cyanide concentration should not exceed 0.005 mg/l, and that effluents containing cyanide should not be combined with any wastewaters containing residual chlorine. |
