The following findings apply to roads in the PSCM permit area. A. Haul Roads Alternative criteria and specifications were not used during the design of haul roads or access roads. (4.03.1(1)(e)). The Division proposes to approve the following roads in the permit area as permanent structures: A, A-1, B, B-1, C, E, and E-1. These roads were previously approved as permanent in the Seneca II Mine permit application based on their compatibility with the approved postmining land uses and landowners' requests for their retention (Findings document for Seneca II Mine, permit C-80-005). The roads will be compatible with the postmining land uses of the PSCM. The haul roads will be reduced to a width of twenty feet, associated disturbance will be reclaimed, and the remainder of the roads left in place. (4.03. 1 (1)(f)(i)). II. Support Facilities - Rule 4.04 Support facilities used in conjunction with the PSCM include the following structures: various buildings (office, security, storage, electrical parts, bath house, pump house, vehicle shop, welding shop, transfer etc.), parking lot, fences, fuel tanks, lube storage area, fuel and oil storage area, power lines, electrical substation, conveyors, mine portal heaters, compressors, ventilation systems, water well, and material and storage yards. All facilities will be constructed to prevent damage or disruption of utility lines, water wells, railroads, and pipelines which may pass over, through, or under the permit area. III. Hydrologic Balance - Rule 4.05 A. Water Quality Standards and Effluent Limitations The Seneca II Mine currently discharges water from sediment control ponds that are fed by storm runoff, spoil springs, and water treatment facilities on lands that, along with the ponds, are proposed for transfer to the PSCM. These discharges are subject to limitations in a permit issued to the operator of the Seneca II Mine through the Colorado Discharge Permit System (CDPS). The discharge permit :includes a Spill Prevention, Control and Countermeasure plan that requires preventative and mitigation measures. In connection with the proposed transfer of lands and ponds to the PSCM, SCCC has applied for a CDPS permit for continuing the pond discharges and adding to them additional runoff that will result from disturbing lands in the PSCM surface facilities areas and pumping of mine water from the underground workings. The Division proposes to grant exemptions from the use of sediment control ponds in three areas on the north side of road A, the office area and two warehouse/boneyard areas. Section 6 of Exhibit 2.05.3-E2 of the PSCM permit application contains a sedimentology model that demonstrates the areas qualify for the exemptions. The exemptions are based on: a) the limited size of each area (total disturbance of the areas Peabody Sage Creek Mine 19 May 7, 2010
