General comments

Subject category Comment text
Environmental Factors THE PRINICIPAL SOURCES OF ACID MINE DRAINAGE (AMD) IN THE AREA HAVE BEEN IDENTIFIED AS THE UNDERGROUND WORKINGS OF THE MAMMOTH MINE (INCLUDES THE FRIDAY-LOUDEN, MAIN MAMMOTH, GOSSAN, AND 300 ADITS), THE GOLINSKY MINE, AND THE SUTRO MINE. A SECONDARY SOURCE OF AMD IS SURFACE RUNOFF THAT PASSES THROUGH WASTE ROCK DUMPS, TAILINGS PILES, AND DISTURBED AREAS. THE MAMMOTH MINE HAS BEEN ESTIMATED TO CONTRIBUTE BETWEEN 87 AND 92 PERCENT OF THE TOTAL METALS DISCHARGED TO RECEIVING WATERS IN THE AREA. ABOUT 300 TO 400 GALLONS PER MINUTE (GPM), AND UP TO 900 GPM FOR SHORT PERIODS DURING WINTER, OF AMD THAT CONTAINS DISSOLVED HEAVY METALS (NBOTABLY IRON, COPPER, IRON, ZINC, AND CADMIUM) ARE DISCHARGED FROM THE MAMMOTH COMPLEX INTO LITTLE BACKBONE CREEK AND SHOEMAKER BULCH. THE MOST ACIDIC WATERS DISCHARGING FROM THE MINE HAVE A PH OF 2.2.
