The operator commits to clearly marking the permit boundary with stakes surveyed on site. The site will use all existing roads to haul the product to its final destination. It is planned that the material may be used to re-surface existing roads, make asphalt or provide new road base for any new roads within an economic distance to the site. In addition to the facilities listed above, the following aze also ancillary to the mining and process- ing activities: * Pazking for workers * Portable office and lab * Equipment storage and maintenance * Portable toilets * Portable fuel and water storage All of these items will be placed in the staging area, as shown on Map C-2. There will be no perma- nent storage of oil, fuel or hazardous material within the permit boundary. Since the storage of these products is temporary, an impervious liner will be installed beneath earthen containment dikes. Dikes will be constructed in a fashion to contain at least 110 percent of the volume of the lazgest storage vessel within the containment area. Operations within the pit area will generally be limited to the hours of 6:00 A.M. to 7:00 P.M. and will occur intermittently throughout any given year. 7. HYDROLOGY AND SEDIMENT CONTROL FOR MINING No major streams or intermittent streams intersect the disturbed azea although the Colorado River is located approximately 600 feet to the south of the southern edge of the permit area. Sediment con- trol for the permit azea is provided by 3 items: I) An earth berm will be placed on the existing ter- rain along the perimeter of the site. All runoff from the Gilsonite Pit disturbed azea will be trapped inside this berm and will primarily enter the pit excavation. The berm will be a minimum of 2.0 feet high with 2SH:1 V sideslopes. It will be constructed from previously disturbed soil pushed up from past excavation of refinery ponds at the perimeter of the permit azea, 2) a small v-ditch of 1.5 feet Gilsonite Pit 9/03 20
