Mr. Bruce Humphries <br /> February 21, 1991 <br /> Page 2 <br /> the Marshall Pit Reclamation Area and not be deposited in the Deepe Pit <br /> reclamation area as originally proposed in the Deepe Farm Permit is <br /> approximately 108,000 cubic yards (165,000 cy- 57,000 cy). The total volume of <br /> slurry materials being deposited from Deepe Pit mining on the Deepe Pit site <br /> in the approved plan was estimated to be 387,000 cubic yards. It is our opinion <br /> that the 108,000 cubic yards which will no longer be deposited on the Deepe <br /> Pit site but which would instead be deposited on the Marshall Pit site will not <br /> have a significant impact on the reclamation planning for the Deepe Pit. <br /> Enclosed is a copy of the currently approved reclamation plan for Deepe Pit. <br /> On this approved drawing we denoted the area where the Deepe Pit slurry <br /> materials that are now going to be deposited at Marshall Pit were to be placed <br /> originally. Final grades on the portion of the Deepe Pit site to be covered by <br /> this deposition will now be on average approximately 4 feet lower than the <br /> originally approved plan. <br /> Based on our previous discussions with Mr. Dan Hernandez, it is our <br /> understanding that this change is minor enough on the Deepe Pit site that <br /> complete revision of the cut and fill calculations and final grade reclamation <br /> plan grade mapping will not be required by the MLRB as part of this requested <br /> Technical Revision. <br /> Attached please find letters from representatives of the permitees of the <br /> referenced permits authorizing Scott, Cox & Associates, Inc. to file this request <br /> for technical revisions. <br /> If you have any questions concerning this permit, or processing this permit, <br /> please call me as soon as possible. <br /> Sincerely yours, <br /> SCOTT, COX & ASSOCIATES, INC. <br /> BY <br /> William H.
