Maximum processing is approximately 3,000 tons per day. Since a portable crusher is used, the location of the cntshing operation changes as the mining proceeds across the resource area. Crushing apparatus will be operated under the stipulations contained within the Construction (Airy Permd issued by the Colorado Department of Public Health and Environment. Approximately 20,000 tons of used asphalt pavement and concrete rubble may also be stockpiled within the extraction area for future crushing. Once the asphalt and concrete are crushed to proper size, i1 is stockpiled for use as recycled materials in new construction. HAUL ROAD -Private ddve access to the site is gained from River Road which is well maintained and in good repair. Anew 150 foot long paved surface haul road will be constructed between the roadway and the mine site together with a new 750 foot Tong acceleration lane along the south side of River Road. The alignment of the haul route extends to the mine floor and is shown on the accompanying Mining Plan Map. The haul road location will not change between the point at which it reaches the mine floor and River Road, until the last phase of mining occurs. ~- The following minimum standards will be incorporated into the haul road construction: `~- Received ', • 28 foot paved width with 3 foot gravel shoulders Eight inches of compacted Class 6 Aggregate Base Course surface '~~ N ~ $ 2~~6 50 foot returns • 18 IRCh Culvert (;rand Junction Field Offica • Stop Sign Olvialon o1 Minerals & seolog~ • Any other improvements required by Mesa County's Access Permit Speed limit and other traffic control signs will be installed along the entire length of the haul road and within the mine site. Water will be used on a continual basis to control dust on the haul road and within the mining area. PETROLEUM STORAGE- There will be no permanent storage of fuel on the site. However, a 10,000 gallon portable diesel fuel tank will be located near the gravel crushing unit when it is present. All fuel will be stored in above ground steel tank(s) and will have a neoprene liner below a layer of soil and in the containment dikes to prevent any discharges of fuel from leaving the site or percolating into the ground.
