STATE OF COLORADO DIVISION OF MINERALS AND GEOLOGY Department of Natural Resources 1313 Sherman St., Room 215 Denver, Colorado 80203 Phone: {303) 866-3567 FAX: (303)832-8106 Apri129, 2002 Banks and Gesso, LLC Attn: Tug Martin 720 Kipling Street, Suite 117 Lakewood, CO 80215 RE: File No. M-2001-046; Nix Sand and Gravel Mine; Owens Brothers Concrete Company; Adequacy Review Responses Deaz Mr. Martin: D r V 15 (O N O F MINERALS GEOLOGY RECLAMATION MINING•SAFETY Bill Owens Governor Greg E. Walther Executive Director Michael B. Long Division Director Our office received your adequacy responses to our letter of Mazch 12, 2002 on April 18, 2002. This response addressed many of the outstanding issues identified during our initial and subsequent adequacy reviews, however, there are still a few areas that will need to be addressed in more detail in order for us to render a fmal decision on your application. The new decision date for this application is May 31, 2002. As May 31, 2002 is the 365`s day since the application was called complete, and in accordance with Rule 1.4.1(9), if at the end of the 365 day period (for review of an application), the application has outstanding adequacy issues, the Office may set the matter for a Board hearing. At the hearing the Board may deny, or approve the application with or without conditions. Therefore it is important that every attempt be made to address the remaining issues prior to the decision date. Following is a list of the remaining items. The latest iteration of the reclamation plan map revises the post-mining topography to show that the majority of the excess over-burden will be placed along the south side of the affected area, thereby, expanding the distance between WCR 28 and the edge of the reclaimed lakes. This appears to be a good plan with respect to mitigating future impacts to the wetlands south of WCR 28. Unfortunately, the overall slope as illustrated on this map is presented as 2H:1 V and Rule 3.1.5(7) requires that in cases where lakes are proposed as part of the reclamation plan, slopes shall be no steeper than 2H:1 V except from 5 feet above to 10 feet below the expected water line where slopes shall be not steeper that 3H:1V. Please revise the map to show that the final reclaimed slopes will comply with this rule. 2. The mine plan map needs to be revised to show all major features of the mining plan such as topsoil stockpiles, overburden stockpiles, product stockpiles, plant location, the direction that extraction will proceed in each phase, etc. (Rule 6.3.5).
