Shelton Director September 16, 1982 Mr. George Gregg General Manager Va1co, Lamar Concrete Division P. O. Box 591 Lamar, Colorado 81052 RE: Lamar East Pit - File No. 77-527 Dear P1r. Gregg: I have reviewed your annual report of btarch I9, 1982 for the above captioned operation. I have also reviewed the report of my inspection of November 11, 1981 (copy enclosed, for your convenience of reference). In Light of these two documents, my recollection of my visit to the site, and my meeting with valco personnel, I have tried to arrive at an overviera of the mining operation. I will present this overview and my evaluation of the status of the permit in this letter. Your annual report clearly outlines the areas mined in the past year and the areas planned for mining this year. This responds to my recommendation no. 3 but does not respond to the other four recommendations in the inspection report. I realize that the problem with the fluctration of the water table in the various ponds on the affected land makes it difficult to outline exa.,t plans for sloping of the ponds. However, if this condition persists, the ponds may have to be sloped with such fluctuations being considered. Slopes o.f 3:1 may have to be lengthened to a greater depth te•be sure of complying with the sloping requirements of Rule 6.1(f). As the water table fluctuation:; are a new factor in the conditions of this site, a new plan seems to be Headed. At the present time, the total reclamation bond on this operation is 515,370.00 (at a rate of $1,000.00/acre for 15.37 acres). It was clear to me during my inspection that considerably rrpre than I5.37 acres have been disturbed (reference my observation no. 2). It is cleai that the reclamation costs and total area disturbed need to be recalulated and reevaluated in light of the actual disturbance on the permit area.
