There is a refuse disposal area 600 feet northeast of the pond. This fill was constructed with <br />coally material and underground development waste. There is a rock underdrain beneath the fill. <br />There is no record of this drain ever discharging water. At the time mining ceased, the fill was <br />only about 8-10 feet high. The fill was covered with noncombustible material and seeded. The <br />rock outcrop behind and above this refuse fill appears stable and has not changed visibly during <br />the past 8 years, since this inspector first visited the site. Runoff from the refuse area, as well <br />as the area uphill from the pile, is diverted into a ditch and routed to the sediment pond on the <br />mine bench. <br />A fill which was placed in Lewis Gulch was removed during reclamation in 1995. Most of the <br />material from the fill was placed on the mine bench and in a road cut uphill from the Lewis Gulch <br />Fill. Outslopes of the area where the fill was located are steep 11 h:1 vl but, appear erosionally <br />stable at this time. There are several 1-3 inch deep rills on the steeper portions of this area. <br />Erosion control matting which was placed on the slope has been destroyed by cattle. The <br />reclaimed channel in Lewis Gulch is in good condition at this time, and shows little evidence of <br />any surface flows. The backfilled road cut above this are also appears stable at this time. <br />The mine access road within the former permit area is in fair condition. There is a fair cover of <br />road base remaining on the road. Several 2-3 inch deep gullies have formed in the road as a <br />result of storm runoff. The road ditch next to this road is functioning. <br />Vegetative cover on the reclaimed area is minimal. It appears that emergence of vegetation <br />following seeding was somewhat successful. However, the area was very heavily grazed by <br />cattle in 1996 and very little perennial vegetation was present at the time of this inspection. <br />Most of the vegetation present at this time consists of annuals, some heavily grazed grasses, a <br />few scattered specimens of rubber rabbitbrush, and some Canadian thistle. The Canadian thistle <br />needs to be monitored and treated if necessary to prevent an infestation of noxious weeds. <br />Established or desired species should also be monitored during the next year. If establishment <br />of perennial vegetation is not successful and/or if over grazing continues to prohibit <br />establishment of an effective vegetative cover, consideration may need to be given to fencing <br />the area to keep cattle out until vegetation is established. <br />Disturbed area runoff from the lower bench and the refuse disposal area drains to the sediment <br />pond. Runoff from the Lewis Gulch fill area and two former topsoil stockpile areas next to the <br />mine access road are treated by silt fences on the perimeters of these areas. The silt fences at <br />the fil! are mostly intact at this time. The silt fences at the topsoil stockpile sites have been <br />destroyed by cattle. <br />There are two ground water monitoring wells which were used during the life of the mine. They <br />were known as the TPW-1 and the Caldirola wells. Neither of these wells has been reclaimed. <br />COAL SALES AREA <br />The coal sales area consists of approximately 5.6 acres of reclaimed ground. All structures <br />were removed from this area, except for a small sedimentation pond. The area is generally flat <br />and stable. Agate across the road at the entrance is locked and a mine identification sign <br />remains in place nearby. <br />The sediment pond is incised into the ground. There is a partially crushed steel discharge pipe <br />and crock-lined emergency spillway. Inslopes of the pond are fairly well vegetated. The pond <br />tends to hold a small amount of water during the winter and spring. Storm runoff from the <br />reclaimed area drains to this sediment pond, with the exception of a small area at the west end <br />of the yard. Runoff from this small area passes through a silt fence, which was still functional <br />at the time of this inspection. <br />
