999 <br />STATE OF COLORADO <br />DIVISION OF MINERALS AND GEOLOGY <br />Department of Natural Resources <br />1313 Sherman St., Room 215 <br />Denver, CO 80203 <br />Phone: (303r 86F6~1356: <br />FK~ay3 CO837 `!~~ <br />Mr. Mitchell S. Rollings <br />Office of Surface Mining <br />505 Marquette NW, Suite 1200 <br />Albuquerque, NM 87102 <br />RE: Notice of Violation C-92-015, Twin Pines No. 2 Mine, <br />Twin Pines Limited Investment Permit No. C-83-054 <br />Dear Mr. Ro s: ,ti(i~~~ <br />Please find enclosed per your request the following items regarding the <br />Twin Pines No. 2 Mine: <br />pF' COQ <br />~~ a <br />N~ o <br />++ <br />X8'!6 ~ <br />Roy Romer <br />Governor <br />Michael B Long <br />brvision Diretior <br />1. Ditch designs, pages 80a, 80b, and 80c, dated April 28, 1983. <br />2. Correspondence from Lawrence G. White, the consulting engineer for <br />Twin Pines, dated August 14, 1992, regarding the ability of the <br />ditches to contain a 10-year precipitation event. <br />3. Mine Site Map TP-3, revised August, 1992, to include the ditch <br />cross sections on the map. <br />Our review of Item No. 2 above indicates that one of the four ditches was <br />still out of compliance at the time of the July 16, 1992 inspection. This <br />seems to be indicated in the last two sentences of the main body of the letter <br />that reads, "To maintain compliance and impede continued erosion, the access <br />road from the Mine Site will require some repair work. The other site roads <br />and drainage facilities are satisfactory in their present condition for the <br />intended use." As such, it appears our vacation of the Notice of Violation <br />was inappropriate. <br />Because of this, the Division is proceeding with reissuing this Notice of <br />Violation for this one ditch. The abatement for the violation will require <br />the operator to reestablish the ditch to the designs included in Map TP-3 <br />within one week of the date of the operator's receipt of the NOV. Should the <br />re-issued Notice of Violation or its abatement change during the <br />Assessment Conference process, we will notify you. Please call me if you have <br />any questions. <br />Sinperel~/(~' <br />Daniel I. Hernandez <br />Senior Reclamation Specialist <br />DIH/amm <br />Enclosure(s) <br />7533E <br />
