since the mine has been in temporary cessation since at least <br />1989. The disturbed portions of the site are dominated by <br />annual weeds and some seeded species such as Pubescent <br />Wheatgrass, and Wild Rye. We did not observe any signs of <br />excessive erosion. The sediment control facilities appeared <br />to be generally in good repair. The fan facility includes an <br />alternate sediment control berm and silt fence. While the <br />structure appears to be adequate to control runoff from the <br />small site (about 60 feet in length and 30 feet wide) it has <br />not been approved by DMG as an alternate sediment control <br />structure. We also noted a small area just south of the "dirt <br />pile" that also does not report to a sediment control <br />structure. Again, it is a very small area, very similar in <br />size to that of the fan site. But, in this case any runoff <br />would not report to a sediment control structure. Therefore, <br />the DMC representative indicated NOV C-99-23 would be issued. <br />The NOV references Section 4.05.5(1) of the Colorado rules as <br />the standard violated. The violation is referenced by the <br />number 2 at performance standard code QI on the Mine Site <br />Evaluation Inspection Report form. <br />The inspection of the road included observations of the <br />culvert crossings, the small ditches along the upslope <br />periphery of the road, the culvert down spouts and the silt <br />fences and sediment Lraps. The road surface is generally <br />free of erosion. In some places along the road surface we <br />noted an abundance of annual weeds. The inspection of the <br />road and its appurent structures was generally uneventful. We <br />confirmed that disturbed area markers are in place along the <br />road as well as the mine site. The markers consist of 4 foot <br />lengths of 3/8 inch diameter rebar painted orange. We had <br />some difficulty in Locating the markers because the native <br />vegetation has grown around then such that they were not <br />readily visible. We inspected the topsoil stockpile located <br />adjacent to the road. A sign is in place identifying the <br />stockpile. Sediment control for the stockpile is provided by <br />a perimeter toe berm and silt trap. The structure is an <br />approved SAE. There is a mine identification .sign located at <br />the entrance from the public road. <br />The field inspection also included observations of the "Loma <br />Loadout". This part of the inspection was also uneventful. <br />The loadout consists of a rail road siding situated on a <br />rectangular shaped area approximately 75 feet wide and 1300 <br />feet long. .Sediment control is provided by a designed <br />perimeter berm and silt fence outlet. We did not observe any <br />evidence to .suggest that there had been any recent discharge <br />of runoff from the site. We noted a permit identification <br />sign at the entrance to the area and the boundary was marked <br />by the same orange rebar as used at the mine site and road. <br />We also noted some concrete barricades Located at the entrance <br />to the Zoadout. The permittee's representative indicated that <br />9 <br />
