county road (BB 27) which goes west from 2700 Road approximately 1300 feet south of the <br />Sunshine Ranch Corner and ends at the Morgan house. An extension of this road will be <br />provided to the Enstrom, Johnson and Wilcox properties. These are the only users of the western <br />portion of BB Road who will be affected by the operation. The Morgan extension road will be <br />installed to BB Road as shown on Map 2.05.3(3)-8 Mine Roads. BB Road ends at the Wilcox <br />property which maintains his access. Johnson and Enstrom use their existing driveways from BB <br />Road and then use the Morgan extension to get out to BB 27 Road and then to 2700 Road. BB <br />Road West will be restored as the pre-existing dirt road for reclamation. <br />The only traffic that will be slightly inconvenienced as a result of mining operations will be that <br />traffic that travels from north of the operation directly south on 2700 Road or in the opposite <br />direction. This is a small percentage of the traffic that uses the BB Road/2700 Road intersection. <br />This traffic would have to use the detour to go to the town of Nucla, approximately 1.0 miles <br />further east. In some cases, the destination of this traffic is somewhere south of Nucla, so there <br />may actually be no additional distance traveled. This detour is expected to be in effect from the <br />time 2700 Road is excavated in mid -2001 until mid -2006 when the road will be replaced with <br />gravel. The following year, the road would be paved in its original location. <br />2. BB Road Detour Design Details <br />A detailed plan with engineering drawings of the detour has been supplied to Montrose County <br />for approval together with the revised special use permit application for the mine in July of 1999. <br />Final approval was granted, and documentation is shown in the Special Use approval in <br />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 year <br />2000 when mining will require the use of the detour. The detour will be 4550 feet long and will <br />be installed to the Montrose County Road and Bridge specifications for collector roads. This <br />entails the following items: <br />a. A right of way of 60 feet (the same as the existing road), <br />b. 1.25" thickness of chip seal <br />c. 4" thickness of class 6 road base <br />d. 14" thickness of class 2 pit run gravel where the largest size stone will be 8" in size <br />e. Chip seal width of 24.0 feet (same as existing road) <br />f. Total Road width = 26.0 feet <br />g. 2% grade from centerline to each side <br />h. 4% super elevation on curves <br />i. Compaction of all surfaces to 95% AASHTO T 180. Test results throughout the road <br />length will be submitted to the County demonstrating this compaction. <br />Section 2.05.3(3) Page 32 September 2017 (TR -81) <br />
