(Page 2) <br />MINE ID # OR PROSPECTING ID # M-1977-227 <br />INSPECTION DATE 10/18/05 INSPECTOR'S INITIALS RCO <br />OBSERVATIONS <br />This inspection was performed bythe Division as part of its monitoring of Construction Materials 112 permits, and in response <br />to the operator's request for an inspection prior to commencing final reclamation. The operator was contacted about the <br />inspection, and the operator's representatives named on page one were present during the inspection. Also present during the <br />inspection were Bob Larson, geologic consultant for the operator, and Bob Fratti, reclamation contractor for the operator. <br />The required permit ID sign was posted at the southern entrance gate. Several of the permit boundary markers and other <br />locatable points along the boundary were indicated during the inspection. There is extensive pre-law disturbance around the <br />permitted area, but all activity carried out under this permit appears to be contained within the permit boundary. (The file <br />contains a very clear aerial photo of the site, dated 1978, which was used to determine the extent of permitted activity. A copy <br />of the photo will be attached to this report and sent to all parties, for their information.) <br />The several onsite structures have been removed down to their concrete floors and foundations. None of the floors indicate the <br />former presence of generators or other attached heavy equipment, so the concrete is expected to be approximately 4 inches <br />thick with medium reinforcing. A hydraulic hammer or large loader should easily break the slabs. There are also several <br />concrete bin walls and retaining structures. These are thicker and possibly contain heavier reinforcement but, again, the <br />operator's normal equipment should be sufficient to break it into the pieces. Disposal of the broken concrete may consist of <br />burial in place or pushing it into the large pit several hundred feet away. <br />There is a short overhead powerline spur leading into the site from the south. It ends at a tagged transformer, with no visible <br />lines leading away. The powerline and poles were declared to belong to the local electric utility; the removal is not the <br />operator's liability. There is minimal onsite debris, and no contaminants. <br />A few stockpiles of crushed and sized cinders still exist on the central pad and at the bins described above. The central area, <br />about 5 acres in size, is also covered with a generally thin layer of cinders. There are several pits at the site, some with fairly <br />level floors, and some with durable basalt outcrops, but generally all with slopes that are steeper than the maximum approved <br />in the reclamation plan. There are also a few shallow test pits that were dozed out near the excavated pits; these too will be <br />backfilled or graded. Most of the pits are shallow and will be easily graded to final gradients. It was agreed that the basalt <br />outcrops may remain, since they are stable and are not readily worked with earthmoving equipment. <br />The large north pit is 40-50 feet deep, and by far is deeper than the other pits. It also contains basalt outcrops on portions of its <br />steep walls. There are areas of steep slopes, and areas of vertical walls and benches. Reclamation of this pit could involve <br />simple cut and fill grading of the walls to attain the approved maximum gradient, but thatwould be quite extensive and increase <br />the footprint of the pit. Due to the variable nature of the slope material, it is possible that several methods of reclamation may <br />be employed on different portions of the slopes. The NE wall contains several benches, somewhat discontinuous and random. <br />The eastern wall contains a large visible outcrop that could be utilized as a stable portion if a new bench were constructed. The <br />southern wall is comprised of loose material that may be easily dozed down. If any items (from demolition or other rubble) are <br />to be buried onsite, this would be the area to place them to be backfilled. The existing reclamation plan does not include <br />extensive use of steep walls and benches, though if the grading plans discussed onsite are to be implemented, they must be <br />revised under a technical revision (TR). <br />There are numerous areas along the west and NW margins containing overburden and topsoil piles. The approved <br />reclamation plan requires that this material is to be used to cover the cinders and scoria wherever earthwork and grading has <br />been performed. There are disturbed areas with exposed cinders on the surface, however, that are becoming naturally <br />revegetated. It was agreed that the reclamation earthmoving should be carried out carefully, to avoid redisturbing certain <br />overburden and cinder areas, so that they would not require reseeding. <br />The species observed growing on the overburden and cinders mainly included rabbitbrush, saltbush, and broom snakeweed, <br />with minor amounts of blue grama and winterfat. Blue grama was the dominant species growing on surrounding undisturbed <br />land. The approved reclamation plan does not include some of these species that exhibit good success growing on these <br />materials. Given that, plus the age of the existing seed mix plan, it is suggested that the local NRCS office be contacted to <br />verify if the existing seed mix is still optimum for this site. If the operator wishes to change the seed mix, it may done through a <br />technical revision (TR). It should be noted that samples of the surface material were taken by the operator to be analyzed for <br />use as a "growth medium" The anavses should be forwarded to NRCS if a revised seed mix is to be developed. <br />Near the concrete structures at the entrance two small, well-established patches of noxious weeds were observed: Canada <br />
