Environmental Factors THERE WERE NO MILL TAILINGS ASSOCIATED WITH THIS SITE. THE ONLY POTENTIAL ADIT DISCHARGE WAS A SEEP AT THE TOE OF WASTE ROCK DUMP 1 THAT DISCHARGES INTO THE MAN-MADE FLUME. THE FLUME SUPPLIED WATER TO CHESSMAN RESERVOIR. THIS SEEP WAS DISCHARGING AT A FLOW OF LESS THAN 1 GPM WITH A PH OF 6.67. THE SAMPLE OF THIS DISCHAGE EXCEEDED THE MAXIMUM CONTAMINANT LEVEL FOR ARSENIC. A SMALL INTERMITTENT TRIBUTATRY TO TENMILE CREEK CONTACTED SEVERAL OF THE WASTE ROCK DUMPS. OBSERVED RELEASES WERE DOCUMENTED FOR ARSENIC, LEAD, AND ZINC. NO MAXIMUM CONTAMINANT LEVELS WERE EXCEEDED THAT WERE DIRECTLY ATTRIBUTED TO THIS SITE. A WATER SUPPLY FLUME FOR THE CHESSMAN RESERVOIR CROSSED THIS SITE. WASTE ROCK FROM WASTE ROCK DUMPS 1 AND 5 SLUFFS OR ERODES INTO THIS FLUME AND IS INTRODUCED INTO THE WATER SUPPLY. THERE WAS ONE OPEN SHAFT THAT WAS A HAZARDOUS MINE OPENING.
