Turnpike <br />Gravel Pit, S31, T2N, R68W <br />Dear Mr. Padgett, <br />Environmental Support for: <br />• Tr~nsportatran <br />+ Wntl Oe velapmenl <br />• Mining <br />• Industry <br />The Colorado Division of Minerals and Geology requires notification to owners of <br />permanent man made structures within 200 feet of the affected land. The pit <br />excavation in this case defines the affected land. The pit area is the actual limit of <br />excavation. Pit reclamation will leave a pond that will occupy the pit boundary. <br />The proposed excavation will encroach Patina structures as shown in the enclosed <br />draft mine plan. The plan excavates as close as 10 ft from patina flow lines and 40 ft <br />-from the well (Patina Cinque 7-31) as a temporary condition. The plan will backfill a <br />setback of 25 ft from flow lines and 150 ft from the well within two weeks of <br />excavation (permanent). <br />The Division of Minerals and Geology Construction Materials Rule 6.4.19 (c) states: <br />Where such a structure is a utility, the Applicant may supply a notarized letter, on <br />utility letterhead, from the owner{s) of the utility that the mining and reclamation <br />activities, as proposed, will have "no negative effect" on their utility. <br />We are requesting that you provide us with a notarized letter as indicated above. <br />Sincerely, <br />e~, <br />Peter Wayland <br />President <br />10335 Caffax Ave..
