contractor was hired to maintain the flume throughout the duration of the high flows to <br />prevent the flume from failing. Roadside ditches and associated culverts were cleaned to <br />pass flows expected during summer thundershowers. Other on site berms and ditches <br />were maintained as necessary. <br />Dutch Creek Flume Repair. The Dutch Creek Flume sustained severe damage during <br />the spring runoff. Large holes were punched through the base of the concrete flume, <br />causing water to infiltrate into the adjacent Old Refuse Pile. Repairs to the flume <br />consisted of installing rebaz and concrete to the floor of the flume, and reinforcement of <br />the furthest down-stream foundation. <br />Mine 3 Reclamation. Reclamation of the Mine 3 area impacted the mine entry area as <br />well as the coal loadout, located approximately 500 feet vertically below the mine entries, <br />and the conveyor corridor that connected these two areas and some Mine Bench <br />Outslopes. Previous to the DRMS reclamation work, a structural demolition company <br />employed by Mid Continent Resources sealed all mine entries, and removed all of the <br />metallic debris from the area. All non-metallic structures, foundations and channels were <br />left in-place for DRMS contractors to demolish and remove. <br />Reclamation work consisted of structural demolition, backfilling and grading, drainage <br />manipulation and revegetation work. Numerous remnant buildings, foundations and <br />beltline foundations were left at the site. All concrete materials were demolished to <br />below ground surface level. The rubble generated at the mine entry area was <br />preferentially placed within the open portions of the mine entries, outby the seals. Excess <br />concrete was placed against the highwall at the entry area, and against the cut slope at the <br />loadout area. <br />The highwall and the loadout cut slopes were backfilled with earthen materials generated <br />on site. Additionally, a large depression located to the north of the mine entries was <br />backfilled to ensure proper drainage of the backfilled mine bench area. Material from the <br />north facing Mine Bench Outslope was excavated to generate fill material, as was the <br />east-facing slope of the mine bench. The slopes above the loadout cut slope were <br />reduced to generate fill for that azea. <br />The entire azea was graded to establish appropriate surface water runoff characteristics. <br />No topsoil was available to support revegetation efforts, so the in-place earthen materials <br />were amended with straw mulch and fertilizer, which were cut into the dirt by dozer. The <br />azea was then revegetated using the U. S. Forest Service -approved seed mixture. An <br />attempt to revegetate the steep slopes below the north facing side of the mine entries and <br />the fill slopes located between the switchbacks of Road F was made. These areas were <br />mechanically roughened. Seed and mulch were applied using a truck mounted hydro <br />seeder. <br />At the time that this work was completed, Mid Continent Resources owned the property <br />at Mine 3. Subsequent to completion of the reclamation work, the property was acquired <br />by the U.S. Forest Service. <br />4 <br />
