OWL CANYON QUARRY (M-77-302) TECHNICAL REVISION - CLARIFICA1rION ON <br />RECLAMATION <br />Dear Tom: <br />In raviewing our records and working with you on updating our financial warranty fa this quarry, we ~ <br />would like to make some GarRcations ro our permit by way of a tecttnicat revisron. <br />First, because vve have invested time and money into rtare detailed aerial photographs, maps and <br />equipment while reviewing your proposal for adjusting our financial warranty, we have more excrete <br />calculations on the actual affected aces in this quarry. The actual affected acraa as of tFie January, <br />1999 aerial photographs for Owl Canyon ~uany is 85,5 acm, nd 105.3 acres as reported in the <br />September, 1997 annual report. We will be adjusting this number in the September, 1h9@ annual <br />report to represent more accurately the currency disturbed Beres in Section 1. We ors currently <br />borttisd for a rtwtlmum disturbance of 106.48 acres. <br />Second, attached please find the clarification to our Exhibit E Reclamation Plan st,ibmitted in <br />March of 1988. We have irxorporated your suggestions as well as Carl Mount's and Bruce <br />Humphries' at»ut the desired divers cation in the final wntours and landscape to assure the best <br />resurts for post mining use of wildlife habitat. By spettifying rtwro hiphwalls, talus slopes, and <br />variations in slopes grades and directions to more closely mimic the surroundings, we hope to clarify <br />the less specific reclamation plan which is currently accepted by the Stale. By identifying various <br />ranges for percentages of acres compared to the total area of higttwalls left, talus copes proposed, <br />and slope variations, ~ have more specifi~lly addressed how the post contours to the land would <br />appear whether the reclamation was completed today a at the lice of the mine. None of the copes <br />proposed are steeper than 2:1 other than the various highwalls and cliffs, as is wrently accepted by <br />the State and 811 of the slopes proposed in the post contour map are both geolechnlcally and <br />erosionally stable. We welcome your input on this reGamation clerRcation. <br /> <br />tre'd SSS:S 20b 026 N3r7 WtlS Wd 95~ £0 56-60-7(lf <br />
