STATE OF COLORADO DIVISION OF MINERALS AND GEOLOGY Department of Natural Resources 1313 Sherman St., Room 215 Denver, Colorado 80203 Phone: (303) 866-3567 FAX: (303)832-8106 June 19, 2003 Mr. Forrest Luke Trapper Mining, Inc. P.O. BOX 187 Craig, CO 81626 Re: Trapper Mine, C-1981-010, RN04/PR-OS Review of May 28, 2003 Adequacy Responses Deaz Mr. Luke: DIVISION OF MINERALS GEOLOGY RECLAMATION MINING~SAFETY Bill Owens Governor Greg E. Walther Executive Director Ronald W. Cattany Division Director The Division has reviewed Trapper Mining, Int.'s responses to the Division's adequacy letter, dated February 14, 2003. Trapper's responses were delivered to the Division on May 29, 2003. Remaining concerns follow: (d) Rule 4.08.2(1) requires that operators provide notice to owners of structures located within one- halfmile of the permit boundary, at least 30 days prior to blasting, of their right to request apre-blast survey. Should Trapper Mining, Inc. not posses copies of such notices sent to the owners of the pipelines identified in proposed Table 3.4-2, we suggest Trapper Mining, Inc. provide, as an exhibit in the DMG permit, copies of formalized agreements between the pipeline owners and Trapper that were referenced in Trapper's responses dated May 28, 2003. If copies of these agreements cannot be found, we suggest Trapper provide copies, again as an exhibit to the DMG permit, of any correspondence indicating the pipeline owners' approval for relocating the pipelines. Copies of any letters from the pipeline owners, indicating their satisfaction with the condition of the pipelines following relocation, would also be important to add to the DMG permit. Trapper Mining, Inc. indicated in its May 28, 32003 response that "Trapper will continue to closely monitor potential blasting impacts to pipelines situated within and adjacent to the permit area." Please provide for inclusion into the permit a description of this monitoring(visual, etc.) and the frequency (weekly, etc.) at which this monitoring will occur. After a telephone conversation with Trapper Mining on June 17, 2003, it is our understanding that Trapper is currently negotiating with a contractor for airblast and ground vibration monitoring. It is our understanding that the contract will describe the number and location of monitoring stations, as well as the frequency with which monitoring will be conducted. Until the Division determines that the monitoring plan is adequate to demonstrate regulatory compliance, however. we must find this item unresolved at this time.
