r- <br />Mr. Michael S. Savage Page Four <br />June 28, 1985 <br />In the future, after Peerless gains experience with underground <br />mining in this area, a technical revision may be submitted to the <br />Division requesting extraction of pillars in areas with less than <br />300 feet of cover. <br />6. The Division requests that Peerless monitor the Victory No. <br />disc arge by we ding a stand Dios or other mechanism on <br />ne. <br />Response: Peerless will weld a stand pipe onto the existing pipe <br />in order to assess the quantity and quality of the Victory No. 3 <br />discharge. The quality parameters will be the same as those <br />monitored for other discharge points in the permit and adjacent <br />area. Flow from the stand pipe will be measured using a stopwatch <br />and a bucket. The monitoring information will allow accurate <br />evaluation of potential hydrologic impacts associated solely with <br />the proposed Peerless operations. <br />7. The a ticant should estimate maximum flows to the sediment ond. <br />he disturbed area rainaae, rness Mc rif in orta isc ar e <br />and Coa u c Aorta isc arge worst case estimate sou a <br />Response: The maximum flows to the sediment pond are set forth <br />in Attachment 2. <br />8. As discussed with Mr. Strid and Mr. Czarnowskv. the existi <br />n aiscnaroe. <br />uivision re nests a aiscussion or wnere the water is Din ana <br />how Peer ess o ans to contain this water. <br />Response: Based upon several field inspections which included a <br />visual check of the embankment structure, we do not feel that any <br />water is being conducted through the embankment of the pond. <br />However, some water may be infiltrating through the base of the <br />pond. Peerless will evaluate this possibility by visual <br />observations and periodic comparison of estimated inflow and <br />outflow rates. If water is infiltrating into the ground, then it <br />undoubtedly finds its way into the coarse unconsolidated material <br />within the Coal Gulch drainage. During the low flow period of <br />late summer, Peerless will visually check the sediment pond <br />bottom and, if indicated, utilize a non-toxic bentonite seal to <br />prevent future infiltration. <br />
