Rd. 21 Haxtun, CO 80731 RE: Washington County 112c Permit Application, Star[in Pit, File No. M-2004-0,21, Adequacy Review Dear Mr. Schafer: COLORADO DIVISION OF MINERALS GEOLOGY 0.EC LAM ATION•N INING SAFETY•SCIENCE Bill Owens Gwemor Russell George Executive Director Ronald W. Cattany Division Director Natural Resourrn Trustee The Division of Minerals and Geology has received your application for the Stazlin Pit 112c Permit. Listed below aze the Division's adequacy review comments for this application. The Division is required to make a decision no later than July 12, 2004, therefore, your response to the following adequacy review concerns should be received by the Division by July 2, 2004 to give us time to evaluate your responses. 1. Exhibit D-Mining Plan The Colorado Land Reclamation Act for the Extraction of Construction Materials, C.R.S.34-32.5- 116(4)(q)(I)states, in part, "All reclamation requirements required by this section shall be carried to completion with reasonable diligence and conducted concurrently with mining operations to the extent practicable. This section then continues to discuss the reclamation of the operation in phases. The Starlin Pit reclamation plan proposes partial reclamation after two phases (of 20 acres each) have been mined. Since it has been estimated that each phase will take about five yeazs to complete, mining might last as long as 10 years, with 40 acres of disturbance, before any reclamation would begin. The Division believes it would be more reasonable to begin reclamation on the back portion of the fast phase as mining begins on the second phase, while leaving up to an additional five acres for processing, lay down and storage requirements. This would allow a 25 acre disturbance at any time, while beginning some reclamation within five or six yeazs of the inception of mining. 2. Exhibit E -Reclamation Plan Under Exhibit E, 2), a), the applicant refers to the seed mix recommendation from The Washington County Natural Resource Conservation Service (NRCS). The seed rates listed for each species in the applicant's Exhibit, such as 1.5 pounds PLS per acre of blue grams, are actually the rates recommended by the NRCS if that species is the only species planted, i.e. 100% of the mix is to be blue grams. Please refer to the NRCS table and examine the column labeled "% of spp. in mix" (20 % for blue grams), and the column "PLS Seeding rate per species/ac" (.3 for blue grams). The PLS Seeding rate per species/ac is the actual seeding rate that should be used in the seed mix. Office of Office of Colorado Mined Land Reclamation Active and Inactive Mines Geological Survey
