Chapter 2 Table 2-1 Design Criteria Topic Design Criteria for the Proposed Action 34. Where construction in or immediately adjacent to WIZ cannot be BMP avoided, specific protection and mitigation measures designed to protect or restore riparian values will be implemented. These may include, but would not be limited to: use of silt fence, berms, straw bales, or other measures to minimize sediment contributions to the riparian area; use of geotextiles as a base for road fills to avoid disturbance of riparian soils; placement of appropriate drainage structures to maintain effective flows through the riparian area, stabilize slopes, and minimize erosion; recovery, stockpiling, and replacement of riparian soils by horizon where soil disturbance is unavoidable; and use of a USFS approved riparian seed mix and riparian plantings. Sediment filters and traps must be used, unless waived in writing by a USFS representative. Silt fencing alone will generally not be considered adequate. All sediment control structures must be routinely inspected and maintained until their function has been replaced by adequate reclamation practices. Road Operations 35. Minnesota Creek, Dry Fork, and Horse Gulch roads will continue to BMP be open for public full size vehicle and ATV use throughout the project. MCC will sign roads warning the public of heavy truck traffic during the active drilling season. 36. All project temporary roads will be closed to public motorized BMP vehicle use during the active drilling season and during the winter months. Motorized will be restricted to administratively approved traffic during this closure period. Locked gates and signs meeting USFS MUTCD requirements will be provided, installed, and maintained by MCC at the intersections of the Horse Gulch and West Flatiron roads, the Dry Fork Road and Long Draw Saddle ATV Trail, the Dry Fork and Upper Deep Creek roads, and any other locations designated by the USFS official. The drilling season is expected to end each year in Septetber, at which time certain temporary roads will be open for public motorized use until snow conditions preclude use. The roads that will be open to public motorized use in the fall include West Flatiron, Long Draw Saddle, and West Bench Roads. 37. By September 1, MCC will post warning signs, at locations BMP designated by the USFS, to wam hunters of dangers associated with increased traffic on roads resulting from project activities, drilling operations, and methane-venting. Depending on the location of drill rigs during the big game seasons (typically only during early seasons), additional temporary gates may need to be installed to prevent public ATV access to active drill sites. Roads closed to public motorized use due to drilling or methane-venting operations shall be clearly posted as "closed" using signs with maps of the closure area and the reasons for closure. At each closure location Manual of Uniform Traffic Control Devices (MUTCD) approved road closure devices must be used. To minimize conflicts with hunters, project traffic will not be allowed on the Minnesota Creek, Horse Gulch, and Dry Fork roads (except for emergency use) . • • 28 Deer Creek Ventilation Shaft and E Seam Methane Drainage Wells FEIS
