Gem Mine, Permit No. M-2002-003 <br />Dear Mr. Rubeck: <br />DIVISION OF <br />MINERALS <br />GEOLOGY <br />RECLAMATION <br />MINING•SAPETY <br />eill Owens <br />Governor <br />Greg E. Walther <br />Executive Director <br />Ronald W. Cottony <br />Acdng Division Director <br />Per our August 30, 2002 phone conversation, if you are changing/modifying your approved <br />mining plan, or approved reclamation plan, you must submit a technical revision outlining the <br />changes/modifications pursuant to requirements of Rule 1.9. A technical revision is allowed if <br />the changes/modifications are not significant. <br />If the changes/modifications aze significant, the revision must be filed as an amendment pursuant <br />to requirements of Rule 1.10. <br />It is my understanding that you may have constructed a diversion ditch System [o direct excess <br />precipitation (or snow melt) away from or through the burnt out azeas in the permit azea. The <br />system should prevent ash and loose sediments from washing out of the permit area so you can <br />protect the adjoining lands. This is a good idea and, actually, a requirement of our statutes (you <br />need to protect areas outside the permit azea). <br />The technical revision (T.R.) submittal must contain a map showing where the ditches are <br />located. Also, the T.R. must include the ditch design information (depth and width, etc.). Include <br />as much information as is available such as; will the ditch system be removed when mining <br />ceases? will the system be changed, or modified, as mining progresses? <br />If you have any questions, give me a call. <br />Sincerely, <br />~i.l~~c-Q-'~- <br />3ames Dillie <br />/~ '.`" _ - <br />Environmental Protection Specialist <br />cc: Hazry Posey (e-mail) <br />
