20) Montrose County has agreed to the plans and has approved of the actual <br />construction based on inspections, reports, etc. Once the road is acceptable, Montrose <br />County will assume the road and will conduct the maintenance. This was done immediately <br />after its installation in the year 2002. <br />21) Once the detour is abandoned, it will be reclaimed. Chip seal surface will be <br />excavated and stockpiled for use in the permanent construction of BB Road west of the <br />Sunshine Ranch Corner. The exact location of the stockpile area has not yet been <br />determined. <br />The road was designed using an accurate aerial topographic map, site survey points for the <br />road centerline and Survcadd civil engineering software working inside AutoCad 14. As of <br />the Mid Term review of 2006, the BB Detour Road has functioned well since its installation <br />and when the paved portions of BB Road and 2700 Road are restored, the BB Detour Road <br />will be removed. <br />Northeast Permimeter Haul Road <br />Professional engineer certified specifications for the intersection with 2700 Road can be <br />found in Attachment 2.05.3(3)-8. <br />Restoration of BB Road and 2700 Road <br />Two paved roads will be restored as part of the reclamation of the New Horizon Mine. These <br />are sections of 2700 Road and BB Road and can be seen on Map 2.05.3(3)-16 in both plan <br />view and profiles. Please see Map 2.05.3(3)-13 for the typical section of how these two <br />paved county roads will be restored. Significant compaction of the underlying fill was <br />required by Montrose County prior to re -paving. Montrose County has approved the plans <br />shown on the above mentioned maps as part of the Special Use Permit approved in 1999. <br />This approval is given in Attachment 2.05.3(3)-8 Montrose County Agreements. The plans as <br />shown meet the County road specifications as collector roads. <br />All permanent drainage structures along these roads have been designed for the peak runoff <br />from a 100 year 24 hour event. These structures are ditches and culverts. <br />BB Road West of 2700 Road (Enstrom, Wilcox, and Johnson access) will be restored as <br />well, however it will be restored as the dirt road that existed prior to mine disturbance. <br />(Revised June 2010) 2.05.3(3)-39 <br />
