Sections of temporary roads with roadway gradient in excess of 12 Road Use <br /> percent or soft areas, which exhibit rusting in excess of 3 inches, Permit (FSM <br /> shall be stabilized by placing an adequate depth of 3-inch minus 2733.04b and <br /> clean crushed rock. The surface of the road shall be maintained to FSM 7730) <br /> minimize ruts and provide for sheet drainage across the roadway. <br /> 29. The USFS officer may require surfacing of temporary roads where Road Use <br /> justified by conditions or traffic volumes. Roads constructed within Permit (FSM <br /> 660 feet of a riparian area will be surfaced with 3-inch minus clean 2733.04b and <br /> crushed rock.

Should avoid wetlands, moist sites; avoid construction in saddles Road Use <br /> and low divides; maintain frequent dense cover areas next to roads; Permit (FSM <br /> construct roads to minimum road standard that will meet 2733.04b and <br /> management objectives (without large cut slopes, fills, or straight FSM 7730), <br /> srietches); and facilitate eventual closure (especially where roads WCPH <br /> enter drainage headwaters areas). <br /> 32.

Federal Coal Lease Stipulation Stipulation <br /> 33. Special design, construction, and mitigation measures jointly Forest Plan <br /> developed by a USFS Interdisciplinary Team and MCC will be <br /> applied to project construction activities proposed in steep slope, <br /> moderate slope, or geologic hazard areas to minimize and control <br /> the potential for slope de-stabilization and erosion. These measures <br /> may include but will not be limited to site-specific drainage <br /> measures, limitations on slope cut/fill angles, slope construction <br /> measures (benching or slope reinforcement such as temporary <br /> gabions or barricades), and slope stabilization measures (such as <br /> geotextile or jute matting or hydromulching). <br />Deer Creek Ventilation Shaft and E Seam Methane Drainage Wells FEIS <br />27 <br />
