Affected Environment and Environmental Consequences <br />Chapter 3 <br />decommissioning techniques such as blocking the <br />routes have not been as effective as complete <br />obliteration and reclamation of temporary roads by <br />eliminating the use of these road prisms. <br />About 13 miles of temporary road have been <br />constructed since 2001 for MDW access. As of <br />summer 2004, about 5.5 miles of road had been <br />decommissioned by obliteration and reclaimed. <br />User-created off-highway vehicle (OHV) trails have <br />proliferated in the area in the last 10 years. MCC <br />assisted Forest Service in closing routes in the <br />methane drainage project area north of the Dry Fork <br />lease between 2002 and 2004. A route down Deep <br />Creek was closed to motor vehicles in 2003. About <br />5.3 miles of user-developed OHV routes were <br />closed in 2003 in the MDW project area. <br />Next 5 Years <br />A planned and designed motorized recreation trail <br />will be implemented at the end of the currently <br />approved methane drainage project (about 2008). <br />The [rail will exist north and west of the Dry Fork <br />LBA tract area and will offer about 6 miles of <br />motorized trail. Ahalf--mile of the trail will lie <br />along the western boundary of the LBA tract. <br />Natural Gas Development <br />Future <br />This area was made available for oil and gas leasing <br />in the 1993 GMUG Oil and Gas Leasing EIS ROD. <br />There has been interest in obtaining gas leases to <br />use the methane resource; however, processing of <br />the parcels has been hampered by the need for <br />analysis of impacts on the Federally-listed lynx. <br />The BLM has officially designated mineral <br />resources to be primarily managed for coal. There is <br />no gas pipeline in the area. MCC and BLM are <br />currently working on potential areas for gas leasing. <br />MCC is also working with the Environmental <br />Protection Agency on possible methane use. <br />Methane Emissions <br />Past 5 years <br />MCC began draining methane from the <br />underground mine via methane drainage wells in <br />2001. Monitoring since then shows the wells have <br />an average active life of about six months. Gas flow <br />averages 600,000 cubic fee[ per day (assuming an <br />average methane concentration of 70 percent). <br />About 10 drainage wells are actively draining <br />methane at any time, and produce between 2 and 5 <br />million cubic feet of methane per day. <br />3.2 TOPOGRAPHY, SOILS AND <br />GEOLOGY <br />3.2.1 Regulatory Framework <br />Authorities specifically governing Forest Service <br />soil management include the Multiple-Use <br />Sustained Yield Act of 1960 and the Forest and <br />Rangelands Renewable Resources Planning Act of <br />1974, as amended by the National Forest <br />Management Act of 1976 (NFMA). The GMUG <br />Forest Plan authorizes and governs management of <br />mineral resources and surface uses over them. With <br />respect to soils management, the GMUG Forest <br />Plan establishes limits on ground-disturbing activity <br />on unstable slopes and highly erodible sites. The <br />Forest Plan further directs using site preparation <br />methods to keep fertile topsoil intact, revegetating <br />areas disturbed during road construction, and design <br />mitigations and restoration to ensure that 80 percent <br />original ground cover occurs within 5 years after <br />disturbance. <br />Regulations adopted pursuant to the Surface Mining <br />Control and Reclamation Act of 1977 and the State <br />of Colorado's OSM-approved permanent program <br />for coal mining per the Colorado Surface Coal <br />Mining Reclamation Act as administered by the <br />CDMG with oversight from the OSM, govern all <br />direct effects of coal mining, including those that <br />may impact soils. These acts and attendant <br />regulations require that topsoil be removed, <br />stockpiled, and replaced on reclaimed surfaces <br />associated with construction or mining disturbance. <br />Other impacts to the soil resource that may occur as <br />a result of mining, including landslides and erosion, <br />must be mitigated to stabilize the surface and return <br />the land to an approved post-mining land use. <br />3.2.2 Analysis Methods and Area <br />For topography, soils, and geology, the impact area <br />is the Dry Fork LBA tract area.
