<br />III. COMMENTS -COMPLIANCE <br />Below are comments on the inspection. The comments include discussion of observations made <br />during the inspection. Comments also describe any enforcement actions taken during the inspection <br />and the facts or evidence supporting the enforcement action. <br />This was a partial inspection of the New Horizon Mine, conducted by Dan Mathews of the DMG Grand Junction <br />Field Office, 101 South 3id, Suite 301, Grand Junction, CO 81501. Weather was clear and warm, with brief rain <br />showers. The purpose of the inspection was to discuss various issues associated with the revegetation plan and <br />standards of success. A number of issues had been raised by the Division during the most recent mid-term <br />permit review, and additional issues have been raised by the operator, notably problems with the approved <br />dryland pasture reference area and problems with the approved production success standard for irrigated <br />pasturelands. Prior to on-the-ground inspection, a meeting was held at the mine office to discuss some of the <br />issues of concern. Individuals present at the meeting in addition to myself, were Ross Gubka of Western Fuels- <br />Colorado (WFC), consultants Greg Lewicki, Steve Boyle, and David Koehler, and Jim Boyd, NRCS District <br />Conservationist. <br />Following the meeting, several field sites were visited; the current dryland pasture reference area in a fenced site <br />on Nucla Airport property, the reclaimed dryland pasture parcel known as the Rice Tract, in the NH-1 area, and a <br />pre-law spoil reclamation area across the county road from the Rice Tract which was reclaimed several years <br />ago by the DMG/AML program, using a relatively diverse rangeland seedmix. <br />No final conclusions were reached at the meeting, which served primarily as a brainstorming session in which a <br />number of issues were presented, and possible approaches to the problems were suggested and discussed. My <br />notes from the meeting include the following points: <br />Irrigated Pasture Issues <br />• Current Standards may be inappropriate for reclaimed areas within portions of the permit area, or <br />perhaps the entire permit area (due to prevalence of shallow, low productivity soil types that are not <br />typically irrigated). <br />• There may be a need for two separate irrigated pasture production standards, based on soil types, <br />replaced thickness, etc. (county road may be likely logical easUwest dividing line). <br />• Production data from 1987 and 1999 may be of significant value to development of standards and logic <br />for changing standards, but detailed precipitation records applicable to the 1987 and 1999 growing <br />seasons will need to be presented (were these "typical" years, above normal or below normal?). <br />Production records (Farm Service Agency) for other irrigated lands in the region may be of use, for <br />making interpretations as to the value of these data. <br />• Correlation of pre-mine soil types with respread reclamation soil thickness? <br />• Revised technical standard would need to be based on soil factors, available records and correlations, <br />input from focal farmers, and NRCS (Norwood District as well as Charlie Holcomb, Area Agronomist in <br />Grand Junction). Use of published data or written records should be relied upon to the extent possible. <br />Dean Stindt, formerly with NRCS Norwood now with BLM may also be of assistance. <br />• "Quality Factors" (i.e. composition) should also be addressed for irrigated pasture and hayland. <br />Dryland Pasture Issues <br />• The most practical management approach for the Rice Tract would appear to be interseeding with <br />dryland alfalfa and grasses, possibly include four-wing saltbush. However, interseeding not allowed <br />under current regulations for pastureland. Only rangeland under specific conditions. Land use change <br />was mentioned as a possible option. Regulatory change might be another option (would need input <br />from NRCS, County Extension service, etc. to support pastureland interseeding as a "normal husbandry <br />practice") to support regulation change. <br />For interseeding, consider "No-Till" drill, or broadcast seed followed by light (spring-tooth type) harrow. <br />• Early fall herbicide application, shortly after germination of storksbill, might be warranted to control <br />competition and enhance potential for establishment of interseeding if conducted in the Rice Tract. <br />Prairie dog control warranted? <br />• If suitable reference area(s) cannot be located for dryland pasture, technical standard may be warranted; <br />NRCS range site descriptions applicable to the permit area may provide some basis or guidance, likely <br /> <br />
