Coa(Rtetham< Drainage Psmjee- PameG 76-24 Wert E!k R-Pine <br />2.3.1 Alternative 1 - No-Action Alternative <br />2-S <br />Analysis of the No-Action Alternative is required by the Council on Environmental Quality (CEQ} <br />' Regulations (Title 40 CFR Part 1502.14(d)). In the No-Action Alternative, the proposed coal <br />methane drainage project would not be approved. The existing mine ventilation system and <br />underground horizontal degasification boreholes would vent approximately 7 million cubic feet of <br />' methane per day. These venting mechanisms, along with the previously completed MDWs, would <br />allow production of approximately 3.5 million tons of coal from current active mining panels in 2002. <br />Production beyond 2002 would not be economically viable with methane venting limited to the <br />' existing mine ventilation system and underground horizontal degasification boreholes. No new road <br />construction, road rehabilitation, drill pad construction, surface drilling, or vertical methane drainage <br />activities would occur in the project area. The network of roads that currently exist in the project area <br />under Alternative 1 is shown on Figure F4, Current and Historic Roads -Alternatives 1, No-Action. <br />' Surface disturbance and related impacts from the coal methane drainage project would not occur. <br />The Minnesota Creek Road, Dry Fork Road, and Horse Gulch Road would continue to exist in the <br />project area. The West Flatiron Road is currently being used Eor access to MI~Ws that were <br />' constructed in 2001. This road would be decommissioned in 2002 or 2003 and reclaimed to become <br />an ATV trail. Existing motorized trails would continue to be open for public and administrative use. <br />2.3.2 Alternative 2 -Sylvester Gulch/Long Draw Saddle Long-Term Access <br />Alternative 2 is the Proposed Action, as described in Section 1.3. A classified road would be <br />' constructed in the project area and used for the next 30 yeazs (approximately 2030) for access to the <br />numng lease area. 'T'his route would begin at the MCC mine facilities area, run south on private land <br />approximately 2.1 miles (the existing Lower Sylvester Gulch Mine Road} until it reaches the National <br />Forest boundary. At the boundary, a new road would be constructed south and east approximately <br />' 1.1 miles along Sylvester Gulch to its intersection with the West Flatiron Road. The route would <br />follow the existing West Flatiron Road For 0.7 miles, then the existing Long Draw Road for 0.4 miles. <br />A new segment of road would be constructed connecting the Long Draw Road to the Dry Fork <br />' Road. This new segment would be called the Long Draw Saddle Road. Once the Sylvester Gulch <br />access route is established and stabilized, approximately 2 miles of the West Flatiron Road, (east of its <br />intersection) with the Sylvester Gulch Road, would be closed and reclaimed. <br />' The existing Minnesota Creek/Dry Fork access would be utilized Eor initial project area access until <br />completion of the Sylvester Gulch access route, in the fall of 2002. The Minnesota Creek/Dry Fork <br />access route would continue to support project traffic for the operation of IvIDWs along the Upper <br />' Deep Creek Road until 2003, or early 2004. After the Upper Deep Creek road and drill pads ate <br />obliterated in 2003 or 2004, this access route would no longer be used Eor project-related traffic. <br />The remainder of the proposed roads are temporary roads. These temporary roads would exist for <br />two to four years. The roads and drill pads would be built and then obliterated sequentially from <br />2002 to 2008 as shown in Tables T1A and T1B. The network of roads and trails that currently exist <br />' or would be constructed in the project azea under Alternative 2 is shown on Figure F5, Existing and <br />Proposed Roads - Alternative 2. Because Alternative 2 would Involve construction of roads and drill <br />pads in restricted azeas, exceptions to the high geologic hazazd; steep slope; and wetland, floodplain, <br />~ and riparian lease stipulations would be required. <br />Under Alternative 2, approximately 2.1 miles of existing roads would be used to access the project <br />area, 11.4 miles of existing road would be used within the project area, 8.6 miles of previously <br />constmcted road or trail would be reconstructed and used as temporary roads, and 4.1 miles of new <br />temporary roads would be constructed. The maximum total length of existing, reconstructed, and <br />new roads in the project azea under Alternative 2 would be approximately 24.1 miles. <br />' Ii~P/M~sv.G1G/E!/D~l/+l0?El USFS EnvironsnentalA.rrerrment <br />e/r/mil,. <br />
