<br />June 30, 1992 <br />Page 7 <br /> <br />identified, however, future monitoring may help define any <br />increasing trend. Spring and Fall testing may help to identify high <br />manganese and iron to be a seasonal phenomenon. <br />CYCC Response <br />No response required. <br />MLRD Concern <br />Surface Water <br />Sites 14, 800, 8 and 900 show somewhat elevated values with regard <br />to conductivity and/or dissolved solids and/or sulfate. Sites 700 <br />and 301 are good quality sites, both of which receive little or no <br />runoff rrcm CYCC mining activities. Site 1002 on Fish Creek and <br />Site 69 on Trout Creek are downstream of all CYCC Twentymile Park <br />mining activities and, at this time, neither show emerging trends <br />or elevated readings leading toward material damage. <br />CYCC Response <br />No response required. <br />MLRD Concern <br />Spoil Springs <br />1. Cadmium and Mercury values are missing for the September 1990 <br />sample. Please explain. <br />CYCC Response <br />Mercury values for all spoil springs were below 0.1 ug/1 during the <br />period in question, but were not reported due to a flaw in the <br />report generation. Cadmium values for the spoil springs during the <br />period in question were inadvertently missed by the lab, and steps <br />to rectify the situation were taken some time ago. Subsequent <br />analysis conducted for spoil springs have included cadmium as <br />required. CYCC apologizes for this oversight, and assures the <br />Division that the matter has been addressed. <br />MLRD Concern <br />2. Spoil spring C1 flowed 170 gpm in May, yet did not get a full <br />suite analvsis. Please explain this discrepancv. <br />
