Discharge from sedimentation ponds, diversions and pit dewatering will be controlled by energy
dissipators, riprap channels, and other means or devices, where necessary, to reduce erosion, to
prevent deepening or enlargement of stream channels, and to minimize disturbance of the hydrologic
balance. Discharge structures will be designed according to standard engineering design procedures.
Transportation Facilities
Haulage Roads. The following describes the design and construction of the existing haul roads at the
Yoast Mine. The locations of existing haul roads are shown on Exhibits 12-1, Operations Plan, and
13-1, Facilities Map. Geotechnical and geological investigations were completed for these roads and
can be found in Attachments 13-5, Geotechnical Investigation Haul Roads Y-A and Y-B, and Pond
010, and 13-6, Geological Report for Haul Roads A and B. Proposed haulroads will be constructed
using the recommendations included in these reports
General Requirements. SCC will construct, maintain and reclaim haul roads to minimize erosion and
siltation, air and water pollution and damage to public and private property. To the extent possible,
using the best technology currently available, haul roads will not cause damage to fish, wildlife, or
related environmental values and will not cause additional contributions of suspended solids to
streamflow or to runoff cutside the permit area. Any such contribution shall not be in excess of
limitations of State or Federal law.
Location. Approximately 5.1 miles of haulage road currently exist within the Yoast Mine permit
boundary. The northernmost section Ithree miles in length) is designated as Yoast Road "A". The
southernmost section 11.1 miles) is designated as Yoast Road "B". A third section (1.0 miles) is
designated as Haul Road D and will be utlllzed as an "out" road from the south mining area at Yoast.
As-Built construction summaries for Haul Roads A, B and D are contained in Attachment 13-11. As-
Built drawings for Haul Roads A, B and D are depicted on Exhibits 13-10.1 [0 13-10.6, 13-11.1 to 13-
11.2, and 13-16 respectively. The topography and vegetation conditions of the site vary considerably,
but can be divided into two general areas. The
