Design Criteria
Topic Design Criteria for the Proposed Action
Maintenance 51. Roads will be maintained with water bars and appropriate Road Use

will be required per the terms of the road use permit. FSM 7730
WATER RESOURCES
Ground Water 53. Any aquifers encountered in the shaft will be sealed by a grout BMP
curtain wall extending 20 feet above and below aquifer.
54. Each drill or borehole, well, or other exposed underground opening BMP
sealed, or otherwise managed to prevent acid or other toxic
drainage from entering ground or surface waters and minimize
disturbance to the prevailing hydrologic balance.
Surface Water 55. Lease stipulations limit occupancy in riparian areas, wetlands and Federal Coal
floodplains. Surface use in wetlands, floodplains or riparian areas Lease
will be avoided unless specially authorized. Stipulation
56. Streams will not be paralleled by roads other than that needed for Federal Coal
crossings. Lease
Stipulation
57. Wetland areas would be avoided wherever possible and BMPs WCPH (FSH
would be implemented for all activities to occur adjacent to or 2509.25) ,
within these aquatic features. Federal Coal

Lease
Stipulation
59. Disturbances to the prevailing hydrologic balance of the affected
land and of the surrounding area and to the quantity or quality of
water in surface and groundwater systems both during and after the
mining operation and during reclamation shall be minimized by
measures, including, but not limited to:
compliance with applicable Colorado water laws and regulations State Law
governing injury to existing water rights;
