December 21, 2011 BLUE EARTH Colorado Department of Natural Resources Division of Reclamation, Mining and Safety Attn: Mr. Berhan Keffelew 1313 Sherman Street; Room 215 Denver CO, 80203 RECEIVED DEC 222011 Division of Reclamation, Mining & Safety RE: Response to Adequacy Review Comments for Schmidt Construction Company Fountain Pit, Permit No. M- 1982 -155, Amendment No. 1 Dear Mr. Keffelew: The following discussion and attachments are submitted on behalf of our client, Schmidt Construction Company, in response to the Adequacy Review comments prepared by the Division of Reclamation, Mining and Safety dated October 25, 2011 for the Fountain Pit 112 Construction Materials Reclamation Permit application. The information and discussion below addresses each comment as it was presented by the Division: 6.4.4 Exhibit D — Mining Plan 1) The Mining Plan — Exhibit D and the Pre - Mining and Mining Plan Map — Exhibit C have been revised to remove the mining options and include only one mining plan. 2) During the majority of the mining operation, surface water from the pit will not drain from the permit area. Only at the very end of the reclamation activities will the mine pit area be graded and stabilized to allow surface drainage off of the permit area. During the mining and reclamation period, the appropriate stormwater discharge permit will be obtained from the Colorado Department of Public Health and Environment and the associated monitoring and stormwater management plan will be followed for surface water discharges. 3) Due to the relatively small size, portable processing equipment will be used during mining of the amendment area. All conveyors will be associated with the portable processing facility. Haul trucks, not conveyors, will be used to transport raw material to the processing facility. For the reclamation warranty, we believe that the portable conveyor could be removed with no cost to the Division. No footings or anchors will remain that could significantly add to reclamation costs. 6.4.5 Exhibit E — Reclamation Plan 1) The Reclamation Plan — Exhibit E and the Reclamation Plan Map — Exhibit F have been revised to remove the reclamation options and include only one reclamation plan.
