Storm Water Management Plan (SWMP), September 2012 GCC Energy – King Coal & King II Mines 9  Fuels and oils are stored in a covered area to minimize contact with stormwater  All fuel and oil storage areas are within properly-sized secondary containment  Spill kits are kept near fuel and oil storage areas  Fueling area is exposed to stormwater, but constructed on concrete pad with rolled curb, overflow directed to catchment pond  Employees are trained in spill response procedures  A Spill Prevention, Control and Countermeasures (SPCC) Plan, consistent with 40 CFR 112.1, has been prepared for the King II Mine 4.5 Erosion and Sediment Controls The King Coal and King II Mines utilize a variety of erosion and sediment controls to reduce erosion and prevent sediment from reaching Hay Gulch. In general, erosion control measures prevent soil or sediment from becoming mobilized, and sediment control measures trap, infiltrate, or settle out mobilized sediments. Erosion control measures include:  Facility roads are watered as necessary to minimize dust generation  Previously disturbed areas and soil stockpiles are vegetated  Rip rap has been placed for energy dissipation in the clearwater and drainage ditches at curves and steep slopes  The outlet from the sediment pond is lined with geotextile and armored with riprap Sediment control measures include:  Both facilities utilize sediment ponds that are designed to contain runoff for the entire facility  Perimeter clearwater ditches are separated from facility stormwater by compacted earthen berms  Facility roads are sloped toward drainage ditches and roadside sediment traps, away from clearwater ditches  Most drainage ditches are directed toward the sediment pond; all others directed to roadside sediment traps and the final sediment trap located at the south end of the access road  A cattleguard located at the south end of the King II access road provides additional protection from offsite vehicle tracking; the trench beneath the cattle guard captures mud and dirt from tires of haul trucks as they drive over it 4.6 Employee Training Facility supervisors are responsible for familiarizing appropriate personnel with procedures as necessary to perform the tasks outlined in this plan. In addition, all appropriate employees receive an overview of the SWMP during Annual
