Permit #0211-BA001

On November 7, 2003, the Alaska Department of Environmental Conservation (ADEC) issued waste management permit #0211-BA001 to Kennecott Greens Creek Mining Company (KGCMC) for the continued disposal of treated tailings from a zinc, lead, silver and gold recovery facility to a lease area with an increased footprint to a total of 123.3 acres (inclusive of disposal area and treatment infrastructure adjacent to the disposal area) and various portions within the underground workings of the mine, and the disposal of waste rock (also known as production rock) to production rock disposal sites 23 and D. The above-ground tailings facility is projected to accept tailings up to a final projected total tailings footprint area of 62.2 acres and total volume of 5.3 million cubic yards (9.6 million tons). The facility includes a marine outfall with diffuser that is used for discharge of waters from the facility under a National Pollutant Discharge Elimination System (NPDES) permit. The above ground production rock facility has a total capacity of 1.2 million cubic yards.
