2.05.3 <br />of 18%. The road is used to access the batch weigh system and to monitor <br />pond K. This existing light use road will not be reclaimed. <br />During 1999 a light use road was constructed to access a drill site in <br />Freeman Gulch. A vent opening will be developed on the drill site, therefore <br />the light use road will be utilized to monitor the vent opening and site. The <br />light use road is approximately 2,600 feet long with an overall average grade <br />of 5%. The first 1,600 feet has an average grade of 10%. The next 300 feet <br />has an average grade of -16%. The next 350 feet has an average grade of <br />7%. The next 200 feet has an average grade of -8% and the final 150 feet <br />has an average grade of 6%. There are two 50 feet segments and one 200 <br />foot segment of the road where the pitch grade exceeds 20%. The drainage <br />area above the point where this road crosses Freeman Gulch is less than <br />one square mile. An 18 -inch diameter culvert will be installed where the light <br />use road crosses Freemen Gulch. This light use road will be reclaimed. <br />Light use roads will be constructed to access drill pads for Gob Vent <br />Boreholes. The roads will be constructed in accordance with rule 4.03.3 and <br />the general guidelines listed above. The layout of the roads are presented on <br />Map 9 Hydrological Monitoring Location Map. During 2008 and 2009 light <br />use roads will be constructed to access thirteen gob vent holes located on <br />USDA -FS managed lands. The light use roads shown on Map 9 were <br />constructed in accordance with the USDA -FS approved generalized road <br />design presented in Volume IIIA, Tab 14 (ref. TR -52). <br />Light use roads that can easily be traveled with an ATV and may be traveled <br />with a 4 -wheel drive vehicle will be upgraded so a drill rig can traverse the <br />road. Light use roads that cannot be traveled with a 4 -wheel drive vehicle yet <br />might be traveled with an ATV will be refurbished so a drill rig can traverse <br />the road. Initially upgraded and refurbished light use roads were estimated to <br />cause about 6 and 12 -feet of new disturbance per lineal feet of road <br />respectively. In 2009 and 2010 the Operator started using 12 -foot of new <br />disturbance for both upgraded and refurbished roads. New light use roads <br />are estimated to cause 24 -feet of new disturbance per lineal foot of road. <br />Vegetation will not be cleared for more than the width necessary to serve <br />traffic an utility needs. <br />A light use road was constructed during May and June 2000 to access Pond <br />B. The entrance for the road is from 4365 Lane. The road parallels Old <br />State Highway 133. It is approximately 600 feet long with a uniform grade of <br />about 1.5 percent. <br />MR -174 2.05-35- 02/15 <br />
