MT8 2.05-31.3 Revised 02/28/22 Williams Fork Strip Pit Reclamation plans for the Williams Fork Strip Pit are detailed in Exhibit 24, Williams Fork Strip Pit Reclamation Plan. The Williams Fork Strip Pit has been reclaimed, and revegetation success sampling was completed in 2005, which indicated that vegetative reestablishment would generally meet the applicable revegetation success standards. MCM applied in 2020 for Phase I, II, & III bond release for this area and was granted release in 2021. Miscellaneous Areas Miscellaneous disturbed areas, associated with the Williams Fork Mines were also reclaimed. These areas include, but are not limited to; the No. 5A powder magazine and various rock dust tanks. Various light-duty roads, and drainage and sediment control ponds and ditches will not be reclaimed until revegetation success has been achieved. All structures and facilities associated with these areas will be removed from the site including all scrap mining material. The areas will be regraded to the approximate original topography. The best available plant growth media will be used to cover the regraded areas to a depth of approximately 6 to 12 inches. The areas will then be planted with a cover crop and subsequently revegetated to the appropriate land use as shown on the Reclamation Plan Map (Map 29). Multi-Service Building MCM s proposing to leave the Multi-Service Building as permanent structure for post mining land use. The 100,000 gallon water storage tank and the large propane storage tank were removed and scraped. Any remaining inert material was placed in the portal area prior to backfilling. Grading, topsoiling, and seeding for the areas associated with these structures are discussed under the 5A portal and Red Rock Crusher sites. Roads and Permanent Roads All of the roads, except those identified on Map 29 as permanent postmining roads, will be removed on completion of mining and reclamation activities. Road surfacing materials will be removed, as appropriate, and placed in the solid waste disposal area, the road surface will be ripped and the road area graded to blend with the surrounding terrain, then graded areas will be topsoiled and planted with a cover crop, then seeded with the appropriate seed mixture. The permanent roads will be reduced in width to approximately 20 feet, and the shoulders ripped and seeded. When the roads are narrowed, surfacing materials will be pulled back from the sections to be reclaimed onto the permanent road surface. All permanent roads will have a similar configuration (cross-section and profile) to a designed access road to assure that the roads remain stable and serviceable after the mining and reclamation are completed.
