ASPHALT quEEMEEM66, SPECIALTIES CO. 10100 Dallas St. Henderson, CO 80640 (303) 289-8555 Fax: (303) 289-7707 RpCp TECHNICAL REVISION NO. 10 FOR MAC uZ 09 TURNPIKE MINING RESOURCE Division of Reclamation, DRMS PERMIT NO. M-2004-009 Vining and Safety Technical Revision ("TR') No. 2 is a simple change to both the mine and reclamation plans on this DRMS permit for the Turnpike Mining Resource site. In short, there is a slight change to the mining and reclamation portions on the southern part of the permit from the 2006 amendment showing two separate mined areas instead of a single mined area, resulting in two post-mining ponds instead of one. We are not moving oil well flow lines by this action, a very costly procedure. In the north portion of the permit area, we are simply increasing the amount and extent of backfill in the reclamation plan versus what is currently approved as part of the 2004 original permit approval and the 2006 amendment. All changes described are shown on the map exhibits, are described in the revised text portions of the exhibits and is reflected in the final reclamation costs of Exhibit L. A simple comparison of the exhibits submitted with this TR to the 2006 amendment exhibits will show the differences. I am also submitting a single copy of a geotechnical report completed last year that shows an engineered liner design and that there are sufficient quantities of the proper type of earthen materials on the site to construct an engineered clay-liner for both the future water-storage reservoir and the ponds. This data consists of a summary cover letter to the report, the text of the report (particularly the "Earthen Liner Recommendations") and all appendices. A typical cross-section through the liner design is attached to this summary. This information is being submitted to reduce the bonding amount on this permit by showing that an engineered liner design has been completed, unlike both in the original 2004 approval of this permit and the 2006 amendment. The bond reduction is determined by the DRMS Asphalt Specialties Co., Inc. is the holder of the DRMS permit for this sand and gravel mining site and is the entity making this TR request as they are the bond holder. Accompanying this text are two copies of the revised mine and reclamation plans (Ex. C- 2 and Ex. F), mine and reclamation plan texts (Ex. D and Ex. E), Ex. L Reclamation Costs and Ex. S Permanent Man-made Structures.
