continues to exceed the numeric protection levels in the other compliance wells? Please explain in <br />detail. <br />8) Squaw Gulch: This area is poorly represented with ground water quality data. The current monitoring <br />wells consists of SGMW -3A (diatreme), SGMW- 3B (alluvium shallow diatreme) and SGMW -5 <br />(bedrock outside diatreme) wells. In addition, there is a shallow piezometer designated as SG -04PZ. <br />Since construction SGMW -5 has been recorded as dry with no water quality data. According to the <br />limited water quality data available, the water quality is characterized as calcium- sulfate dominated. <br />Sulfate values range from 423 mg/1 in the alluvium to 595 mg/1 in the shallow bedrock. The proposal <br />under this amendment is to place a large pregnant solution collection system up gradient of these wells. <br />The location is also in close proximity to Cripple Creek which is a perennial stream. In addition, there <br />is already a very large overburden stockpile up gradient of these wells. Therefore, CC &V must drill <br />additional monitoring wells in Squaw Gulch. Upon completion, these wells have to produce enough <br />water to complete a full suite analysis for five consecutive quarters. Once the five quarters worth of <br />data is submitted, the Division will set numeric protection levels for the selected metals, as indicators <br />in accordance with Rule 3.1.7(iv) and Rule 6.4.24 as applicable. <br />9) Wilson Creek: The location of the phase V pregnant pond required the addition of a new compliance <br />well in Wilson Creek (WCMW3 -134) for early detection. The Division set the following numeric <br />protection levels for the compliance well: pH 6 to 9, wad cyanide 0.2 mg/l, sulfate 250 mg/l, zinc 2.0 <br />mg/1 and manganese 0.5 mg /l. Since the Division never sent a formal letter addressing the new <br />compliance well and the numeric protection levels, please acknowledge this well as a new compliance <br />well, in addition to WCMW -6 in Wilson Creek, with the above numeric protection levels. <br />The other monitoring and compliance wells in Vindicator Valley and Poverty Gulch appear to be <br />adequate at this time. <br />RESPONSE. Please reference Technical Memorandum submitted as Attachment 14 to address appropriate <br />comments above. <br />
