• 2.05.3 7 %. The next 200 feet has an average grade of -8% and the final 150 feet has an average grade of 6 %. There are two 50 feet segments and one 200 foot segment of the road where the pitch grade exceeds 20 %. The drainage area above the point where this road crosses Freeman Gulch is less than one square mile. An 18 -inch diameter culvert will be installed where the light use road crosses Freemen Gulch. This light use road will be reclaimed. Light use roads will be constructed to access drill pads for Gob Vent Boreholes. The roads will be constructed in accordance with rule 4.03.3 and the general guidelines listed above. The layout of the roads are presented on Map 9 Hydrological Monitoring Location Map. During 2008 and 2009 light use roads will be constructed to access thirteen gob vent holes located on USDA -FS managed lands. The light use roads shown on Map 9 will be constructed in accordance with the USDA -FS approved generalized road design presented in Volume IIIA, Tab 14 (ref. TR -52). Light use roads that can easily be traveled with an ATV and may be traveled with a 4 -wheel drive vehicle will be upgraded so a drill rig can traverse the road. Light use roads that cannot be traveled with a 4 -wheel drive vehicle yet might be traveled with an ATV will be refurbished so a drill rig can traverse the road. Generally upgraded and refurbished light use roads cause about 6 and 12 -feet of new disturbance per lineal feet of road respectively. Vegetation will not be cleared for more than the width necessary to serve traffic an utility needs. . A light use road was constructed during May and June 2000 to access Pond B. The entrance for the road is from 4365 Lane. The road parallels Old State Highway 133. It is approximately 600 feet long with a uniform grade of about 1.5 percent. During late 2003 a light use road was constructed to access the material storage area located east of the old power plant, south of pond C. The road is approximately 80 feet long with a uniform grade of about 10 %. During late 2004 a light use road was constructed to access the drill site located above the utility bench. The road is approximately 280 feet long with an average grade of about 10% and a pitch grade of 20% for about 130 feet. During 2010 a light use road will be construct to access the Terror Creek Road. The light use road begins on the west ridge at a road previously constructed to access gob vent hole GVB- B3 -A2. The road terminates at the road leading to monitoring well TC- 03 -03. The road is approximately one mile long with an average grade of 7 %. New light use roads will be reclaimed. Reclamation of the upgraded and refurbished light use roads may involve narrowing the roads so they are compatible with the postmining land use of rangeland and wildlife habitat since roads are necessary to manage both land uses and a light use road network was existing on the property prior to mining. 0 MR -116 2.05-27- 03/10 I�PPRoVED yj � 6
