Proposed Standards <br />The proposed standards found from the methodology explained above can be found below in Table 3. It is <br />proposed that the future well tests from all wells must meet these proposed standards. New tailings produced by <br />the mill will be evaluated with an SPLP test at a minimum of one sample per 6 months. These tests must also meet <br />the standards set forth in Table 3 below. If any test shows a parameter that exceeds the proposed standard, the <br />Division will be immediately notified and corrective action will be proposed to correct the issue. <br />Table 3: DRMS Proposed Standards <br />Parameter <br />Max of Shallow <br />Wells + 25% <br />(mg/L) <br />In- Stream Water <br />Quality Standards <br />(mg/L) <br />CO Ground Water <br />Standards for Agricultural <br />Use Classification (mg/L) <br />Proposed <br />Standard <br />(mg/L) <br />Aluminum, dissolved <br />0.050 <br />5 <br />5.000 <br />Aluminum, total <br />6.400 <br />Report <br />Antimony, dissolved <br />0.003 <br />Report <br />Arsenic, dissolved <br />0.003 <br />0.34 <br />0.1 <br />0.340 <br />Barium, dissolved <br />0.075 <br />Report <br />Beryllium, dissolved <br />0.000 <br />0.1 <br />0.100 <br />Bicarbonate as CaCO3 <br />56.250 <br />Report <br />Boron, dissolved <br />0.013 <br />0.75 <br />0.71 <br />0.750 <br />Cadmium, dissolved <br />0.000 <br />0.0004 <br />0.01 <br />0.000 <br />Cadmium, total <br />0.002 <br />0.05 <br />0.050 <br />Calcium, dissolved <br />50.875 <br />Report <br />Carbonate as CaCO3 <br />0.000 <br />Report <br />Cation -Anion Balance <br />7.875 <br />Report <br />Chloride <br />1.500 <br />0.011 <br />1.500 <br />Chromium, dissolved <br />0.001 <br />0.1 <br />0.100 <br />Conductivity @25C <br />325.000 <br />Report <br />Copper, dissolved <br />0.005 <br />0.008648929 <br />0.2 <br />0.009 <br />Copper, total <br />0.050 <br />0.15 <br />0.150 <br />Cyanide, total <br />0.000 <br />Report <br />Cyanide, WAD <br />0.000 <br />0.005 <br />0.005 <br />Fluoride <br />0.438 <br />2 <br />2.000 <br />Hardness as CaCO3 <br />140.000 <br />Report <br />Hydroxide as CaCO3 <br />0.000 <br />Report <br />Iron, dissolved <br />0.125 <br />1 <br />5 <br />1.000 <br />Iron, Total <br />11.813 <br />1 <br />11.813 <br />Lead, dissolved <br />0.044 <br />0.002407169 <br />0.1 <br />0.044 <br />Lead, total <br />0.726 <br />0.3 <br />0.726 <br />Magnesium, dissolved <br />3.375 <br />Report <br />Manganese, dissolved <br />0.068 <br />1.627311235 <br />0.2 <br />1.627 <br />Mercury, dissolved <br />0.000 <br />0.01 <br />0.010 <br />Mercury, total <br />0.000 <br />1 0.001 <br />1 0.001 <br />14 <br />
