following parameters is performed on a quarterly basis and submitted to the Division in
<br />an annual report: pH, Conductivity at 25oC, Total Dissolved Solids, Bicazbonate
<br />(HCO,-), Calcium (Ca"-), Magnesium (Mg"), Ammonia (NHS), Nitrate, Phosphate (PO,'
<br />as P), Sodium (Na'), Sulfate (SOa ), Arsenic (As), Iron (Fe), Lead (Pb), Manganese
<br />(Mn), Mercury (Hg), Selenium (Se), Zinc (Zn), and Depth to Water.
<br />2. The applicant has conducted, and will continue to conduct, monitoring (see page 4.05-12,
<br />Permit) of surface water in a manner approved by the Division. The sampling sites are: 1)
<br />Taylor Creek near the mouth of the creek, 2) lower Goodspring Creek (downstream from the
<br />mine) and 3) upper Goodspring Creek (upstream from the mine). The monitoring plan was
<br />submitted under Rule 2.05.6(3)(b)(iv) and includes the following [Rule 4.05.13(2)]:
<br />Monthly sampling for: pH, electrical conductivity, temperature, Total Suspended Solids
<br />(TSS), and flow.
<br />Quarterly sampling for pH, Conductivity at 25oC, Total Dissolved Solids, Bicarbonate
<br />(HCO,-), Calcium (Ca"-), Magnesium (Mg"), Ammonia (NH,),Nitrate-Nitrite, Phosphate
<br />(PO,'' as P), Sodium (Na'), Sulfate (SO; ), Arsenic (As), Iron (Fe), Lead (Pb), Manganese
<br />(Mn), Mercury (Hg), Selenium (Se), Zinc (Zn), and Total Suspended Solids (total
<br />recoverable metals).
<br />[n addition to the monitoring discussed above, the operator is required to monitor (see page 4.05-
<br />15, Permit) discharges from all NPDES discharge points (sediment ponds) as required by the
<br />mine's NPDES permit. Results of this monitoring are reported to the Colorado Department of
<br />Health on a quarterly basis and to the Division on a yearly basis.
<br />H. Transfer of Wells -Rule 4.05.14
<br />No transfer of wells is proposed. All monitoring wells will be reclaimed prior to bond release .
