The only traffic that will be slightly inconvenienced as a result of mining operations will be <br />that traffic that travels from north of the operation directly south on 2700 Road or in the <br />opposite direction. This is a small percentage of the traffic that uses the BB Road /2700 Road <br />intersection. This traffic would have to use the detour to go to the town of Nucla, <br />approximately 1.0 miles further east. In some cases, the destination of this traffic is <br />somewhere south of Nucla, so there may actually be no additional distance traveled. This <br />detour is expected to be in effect from the time 2700 Road is excavated in mid -2001 until <br />mid -2006 when the road will be replaced with gravel. The following year, the road would be <br />paved in its original location. <br />BB Road Detour Design Details <br />A detailed plan with engineering drawings of the detour has been supplied to Montrose <br />County for approval together with the revised special use permit application for the mine in <br />July of 1999. Final approval was granted, and documentation is shown in the Special Use <br />approval in Attachment 2.05.3(3) -8 Montrose County Agreements. <br />The existing portion of BB Road through the amendment area will be used until mid to late <br />year 2000 when mining will require the use of the detour. The detour will be 4550 feet long <br />and will be installed to the Montrose County Road and Bridge specifications for collector <br />roads. This entails the following items: <br />1) A right of way of 60 feet (the same as the existing road), <br />2) 1.25' thickness of chipseal <br />3) 4" thickness of class 6 roadbase <br />4) 14" thickness of class 2 pit run gravel where the largest size stone will be 8" in size. <br />5) Chipseal width of 24.0 feet (same as existing road) <br />6) Total road width = 26.0 feet <br />7) 2% grade from centerline to each side <br />Revised June 2010 (PR06) 2.05.3(3) -37 <br />
