RECEIVED 2 g 1995 Division of Minerals a Geology June 23, 1995 Mr. Joe Dudash Colorado Division of Minerals & Geology 1313 Sherman Street, Room 215 Denver, CO 80203 Dear Mr. Dudash: Re: Trapper Mine (Permit No. C-81-010) N.O.V. No. C-95-017 I am submitting this letter as a follow-up to our meeting in your Denver office on June 19, 1995. Enclosed please find a revised work plan, for your approval, to investigate the causes of the Ashmore Pit landslide. The work plan incorporates the changes we discussed at the meeting. Data collection and analysis proposed in the work plan will be under the direction of Vladimir Straskraba of Hydro-Geo Consultants, Inc. Mr. Straskraba is under contract to Trapper for this project. As discussed, Trapper Mine also requests, pursuant to Rule 5.03.2(2)(c)(iv), that the time allowed for abatement actions to the above-captioned N.O.V. be extended. Specifically, we request that the submittal date for a technical revision (TR) which will provide a remediation plan design for the slide area be extended to August 28. This will allow time to complete landslide data collection and evaluation essential to TR development. We further request that the final abatement requirement be modified to "obtain approval of the TR," and that the dead- line for fmal abatement be extended to October 15, 1995. TR approval should be sufficient to terminate the NOV because Trapper will be obligated to perform the remediation work by our permit at that time In addition, it is impossible at this time to accurately estimate the time needed to complete the work, and therefore, how long to request for a final abatement exten- sion after the TR is approved. Alternately, if the final abatement action is not changed, we request that the deadline for implementation of the remediation plan be extended to the later of October 31 or at least 30 days following Division approval to commence remediation work. The reason for requesting these time extensions is because it is not feasible to complete the abatement actions in the time allowed by the NOV. Recent, extraordinary wet climatic condi- tions have made it impossible to mobilize equipment on the slide area for data collection pur- poses until significant drying occurs. A Trapper Mine survey truck became mired to the bottom of the truck doors on June 15 when attempting to get close to the slide area for survey- ing purposes. Larger excavation equipment needed to dig test pits would encounter even greater problems if we attempt to move in before ground conditions allow. In addition, envi- ronmental harm to topsoil and vegetation resources would occur if mobilization occurs before ground conditions are appropriate. We estimate that if the relatively dry climatic conditions P.O. Box 187 Craig, Colorado 81626 (303) 824-4401
