--- -- - Life ofmine operations will include underground mining at the P 1 / P2, P3, R 1 /R2, and R3/R4 portal sites (Map 2.05.3-1). Surface mining will also be conducted throughout the mine plan in the northern portion of the property as indicated on Map 2.05.3-1, Mine Plan. Other surface mine coal is available on the property, as well as coal that can be recovered by the highwall mining method. Life of mine support facilities will include haul and access roads and shuttle train loadou[ facility. Areas to be mined by year is indicated on Map 2.05.3-1. Table 2.05.2-1 summarizes projected disturbance azeas for the first permit term (Years 1 &Z) and part of the second permit term (Years 3-7). Table 2.05.2-1a summazizes projected water needs for the life of the operation. 2.05.3 OPERATIONS DESCRIPTION -FIRST PERMIT TERM (1) Production Methods and Equipment -First Permit Term Map 2.05.3-2 details mining plans for the first five yeazs ofthe operation, including the first permit term and part ofthe second permit term. Only surface mining will occur during the first permit term in the northeast quadrant ofthe property. Mining will commence in the northeast end ofthe ridge between Jeff Canyon and Cow Canyon (JeffCanyon Surface Mine). The coal out crops in Lorencito Canyon (Lorencito Canyon Surface Mine) will be mined in Years 4 and 5. As shown by Map 2.05.3-1, the ridge will be azea mined over the 5-year permit term advancing from the northeast to the southwest. The coal outcrops in Lorencito Canyon will be mined commencing near the mouth of the canyon on the west side, south for approximately 1.5 miles, and then to the east side for approximately 2 miles from the mouth of the canyon. Support facilities include a stockpile and loadou[ area (with crushing and stacking equipment) to be constructed adjacent to the Kem Valley Railroad (south side), haul and access roads, and portable office, warehousing and maintenance and maintenance buildings. All facilities and equipment to be constructed and operated during the first permit term are described in the sections below. All coalbed methane wells located in the mine disturbance will be avoided or plugged and abandoned as negotiations with the landowner are completed. (2) Operation Description -First Permit Term Surface Mine Surface mining activities wil l begin during year one of the mine plan. The fast phase ofsurface mining will begin in the northeast portion ofthe mine area and proceed southwest (Map 2.05.3-2). The area to be disturbed will be cleazed oftrees/brush and topsoil will be salvaged and stored in stockpiles. Overburden and interburden material will be moved to fill areas or used as back fill for previous pits. Overburden material will be moved by a combination ofinethods which include dozers, loader and truck, and cast blasting. Production benches for each majorcoal seamwill be approximately 150 fee[ in width. A maximum of 1,500 lineaz feet of pit will be open at any one time.
