Box 187 <br />Craig, CO 81626 <br />Re: Notice of Violation No. C-95-017, Trapper Mioe <br />Permit No. C-81-010, Trapper Mining Company <br />Dear Mr. Luke: <br />~~~ <br />DEPARTME[VT OF <br />NATURAL <br />RESOURCES <br />Roy Romer <br />Governor <br />lames 5 Lochhead <br />Esecunvc Director <br />Michael B. Long <br />Division Dueaor <br />The Division is issuing Notice of Violation No. C-95-017 for the slide in the scraper pit above the <br />ash pit. The NOV is attached and contains the exact regulation citations. This NOV is the result of <br />several inspections. First, an aerial inspection was flown on May 17, 1995. Second, the photo- <br />graphs from the aerial inspection were examined on May 23, 1995. Third, afollow-up field inspec- <br />tion, pursuant [o Rule 5.02.2(3)(6), was conducted on May 24, 1995. <br />The NOV states that [he abatement is to reestablish the reclaimed area, demonstrating that the static <br />safety factor is 1.3 or greater, per Rule 4.14.2(1)(6). In the interest of communication, the Division <br />strongly recommends that the following outline be adhered to in order to abate this NOV. The <br />Division cannot guazantee that utilization of another procedure will successfully abate this NOV. <br />This slide azea, apparently, also failed in 1993 and the Division wants this problem to be solved so <br />that it will not happen a third time. <br />1. Submit a workplan, for review by the Division, that outlines the procedural steps that will be <br />used to implement part 2 that follows. <br />2. a. Investigate, in the field, the nature and extent of the slide. <br />b. Obtain samples from test pits in the slide area, for later analysis. <br />c. Determine the material sVength characteristics of the field samples, utilizing laboratory <br />analyses. <br />d. Determine the phreatic surface in the slide area and immediate surrounding area, <br />preferably using piezometers, for the present configuration. <br />
