III. COMMENTS-COMPLIANCE <br />Below are comments on the inspection. The comments include discussion of observations <br />made during the inspection. Comments in Section IV describe any enforcement actions <br />taken during the inspection and the facts or evidence supporting the enforcement action. <br />The single purpose of this inspection was to preview a proposed 5,750-foot-long <br />access road alignment up Sylvester Gulch. This road segment would be a <br />connection between two existing roads. The purpose of the road is to provide access <br />to drill pads to the south of the current area of mining, The road starts in the vicinity of <br />the boundary of the SE '/a SE '/4 Section 21 and SW '/a SW '/a Section 22 and extents to <br />the south line of SE '/4 NE '/a Section 27, T13S R90W (see the Somerset USGS 7.5-minute <br />topographic map quadrangle). This route would be an alternate to the current 20- <br />mile (estimate) circuitous route of traveling from the mine site, west on Colorado <br />Highway 133 to Paonia, thence up the Minnesota Creek road, through residential, <br />private properly, and US Forest Service lands. The proposed alignment reviewed is <br />described in a geotechnical report titled Conceptual Evaluation of Sylvester Gulch <br />Roadway Construction Feasibility prepared for Mountain Coal Company, November <br />28 2001, by Buckhorn Geotech. The proposed ground trace had not been flagged; <br />therefore precise slopes, grades, and detail features of the route were not observed. <br />This road would be on US Forest Service property (Somerset quadrangle). The <br />proposed road alignment is nearly superimposed upon an existing trail (old over- <br />grown dozer trail, ATV and snowmobile use) for a third of the project. <br />At the time of this inspection, the proposed alignment was covered by snow, <br />approximately two feet in the valley bottom and north facing slopes, approximately <br />a foot on the south-facing slopes. <br />Ample examples of land slides, slope failures, mass movement, and soil creep were <br />noted during the inspection, and attest to a history of instability of some of the slopes <br />to be traversed. In general north-facing slopes appeared to be less stable than south- <br />facing slopes. Snow cover inhibited notation of wet areas or seeps. In general, south- <br />facing slopes were covered with mature oak (Gambols) brush, the valley bottom with <br />mature but thin or disconnected areas of aspen, and the north slopes with aspen <br />and pine trees. <br />The proposed alignment is not located on ridges, but is located on the more stable <br />available slopes close to the bottom of the ravine/valley of Sylvester Gulch (Rule <br />4.03.2(2)). There are two crossing of the Sylvester Gulch drainage, but no part of the <br />Sylvester Gulch channel is proposed as part of the access road (Rule 4.03.2(2)(b)). <br />Sylvester Gulch has classified as an ephemeral stream on page 2.04-55 of the C-80- <br />007 Permit Application Package and is indicated as an intermittent stream on the <br />Somerset quadrangle. <br />No fatal flaw with the proposed alignment was noted, but compliance with the Rules <br />will be a challenge. The overall grade of the proposed road approaches 10%, and <br />C-80-007, Page _3_ of _5_ Pages, (date) _11 December 2001 (initials) _BGW <br />
