MINING PLAN (CONT) IIR~D® APRIL ZOO2 ExNlslr D on the south side of the site. Additional shaping may take place on the mine side to stabilize that slope but it will generally be left as it is now. In addition, the area shown as Stage A has been incorporated into Stage S and Stage S has been reshaped to correspond with the change to the shape of the berm. Amendment # 8 - SECONDARY ACCESS ROAD The "Secondary Access Corridor" is where a second access road will be built. This road will provide one way access from Highway 6 to the mining area. As a result of the increased demand for product the operator began to plan for future hauling needs in 1999. This increased demand had put more pressure on the single entrance than expected in 1983. The analysis and the current operation indicate that a change is needed to the way trucks enter, flow thru and exit the site. To optimize traffic in and around the mine it has become necessary to add an addi- tional access point into the mine. The new road proposal is to build a one-way access to the mine floor so that vehicles traveling up Highway 6 will enter the mine from the east near where Highway 40 meets Highway 6. This east entrance would nearly eliminate all trucks turning right into the existing entrance and reduce the time trucks coming off I-70 have to sit in the decell lane waiting to make a left turn into the quarry. It would also improve the traffic pattern in the quarry and eliminate some of the circulation problems being encountered now. in 1999 the Frei applied for an access permit from CDOT and received preliminary approval (permit #199103) based on the road being a right in only access. The permit requires a decell lane with a 90 degree turn on to the mine property from the CDOT R.O.W.. The exact details of the entrance design is not known at this time. This will be finalized once we have approval. This 7 (Revised 8/19/02)
