CWA ViolationsRegion 10 Settles with Coeur Alaska Inc. (Juneau, AK) for CWA Violations On July 15, 2019, Region 10 filed an Administrative Order on Consent (AOC) to address violations of the Clean Water Act by Coeur Alaska Inc?s Kensington Mine, located 45 miles north-northwest of Juneau, Alaska. Respondent, which operates an underground gold mine, was improperly releasing acid rock discharge without treatment in violation of the CWA and its Alaska Pollutant Discharge Elimination System (APDES) permit. Coeur Alaska Inc. has agreed to perform specific actions, including: ensuring compliance with a State issued remediation plan by continuing to use the acid rock discharge (ARD) treatment plant; sending a monthly compliance report to the EPA's case officer; ensuring access to the mine and mine records to EPA or EPA's designated representative; and preserving and maintaining all records relating to the AOC. The Environmental Benefits of this enforcement action will be a reduction in the quantity of pollutants discharged into Alaska?s marine waters by improving the mine?s treatment, monitoring, and sampling procedures.
