Sherman <br />March 23, 2009 Executive Director <br />Ronald W. Cattany <br />Asphalt Specialties Co, Inc. Division Director <br />Attn: Rob Laird Natural Resource Trustee <br />10100 Dallas Street <br />Henderson, CO 80033 <br />RE: File No. M-2004-009; Turnpike Mining Resource; Technical Revision 03 - Revise Mine Plan and <br />Reclamation Plan configuration, Submitted by Asphalt Specialties Co., Inc. <br />Dear Mr. Laird: <br />The Division of Reclamation, Mining and Safety (DRMS) has completed its preliminary adequacy review <br />of the Technical Revision (TR03). The revision was received on March 2, 2009 and called complete for <br />review on that date. The decision date for this revision is April 2, 2009. Please be advised that if you are <br />unable to satisfactorily address any concerns identified in this review before the decision date, it will be <br />your responsibility to request an extension of the review period. If there are outstanding issues that have <br />not been adequately addressed prior to the end of the review period, and no extension has been requested, <br />the Division will deny this revision. In general the submission was substantially adequate; however, as <br />with most revisions there are a few items that will require the submittal of additional information or <br />clarification of the existing information. The majority of the comments pertain to the submitted <br />reclamation cost estimate. In the interest of expediting the reclamation estimate process it would likely be <br />very beneficial to meet at the DRMS office to resolve any remaining questions. <br />• It appears that at least one underground gas line and one underground electric line will need to be <br />relocated near the south end of Cell 1. Are agreements already in place with the appropriate utilities for the <br />relocation of these lines? Also, no costs for the relocation of these lines have been included in the cost <br />estimate as submitted. <br />• The feasibility study as submitted does not contain some of the required information (such as material <br />mixing specifications, liner cover specifications, QA/QC protocol, etc) and commitments to be eligible for <br />the reduced bond option. It may be helpful to review pages 8 through 13 of the "GUIDE TO <br />SPECIFICATION PREPARATION FOR SLURRY WALLS AND CLAY LINERS AS A COMPONENT <br />OF A COLORADO MINED LAND RECLAMATION PERMIT" (available on the DRMS website) for a <br />more complete listing of specifications and commitments required for the reduced bond option. Although <br />some of the information from the "recommendations" section is certainly applicable if the appropriate <br />commitments are made, what DBMS will require is much more of a design and specifications report, not <br />just a feasibility study (if the reduced bond option is desired). <br />• The submitted feasibility study states that liner material should be placed in maximum 9 inch lifts for <br />compaction, but the text of Exhibit E states it will be placed in one foot lifts. Please change text in Exhibit <br />E to 9 inch maximum lifts, or provide documentation to support the one foot lifts for liner construction. <br />• The figure included with the TR (Reservoir Clay Liner - Typical Cross Section) does not correspond <br />with the recommendations provided in the feasibility study. In particular, the feasibility study recommends <br />office of Office of <br />Mined Land Reclamation Denver • Grand junction • Durango Active and Inactive Mines
