This map shows the planned schedule for the mine advance throughout the life of mine. ' Separate five-year renewals will be obtained and a performance bond will be posted as necessary. The mine lease area comprises 17,862 acres while the initial permit area is 3,142 acres. The actual surface disturbance azea associated with the operations will be approximately ,; ` 655 acres during the first five years of mining. Life of mine operations will include underground mining at the P 1/ P2, P3, RI /R2, and R3/R 4 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 high wall mining method. Life of mine support facilities will include haul and access roads and shuttle train loadout facility. Areas to be mined by year is indicated on Map 2.05.3-1. Table 2.05.2-1 summazizes projected disturbance azeas for the first permit term (Yeazs 1 & 2) and part of the second permit term (Years 3-7). Tab1e2.05.2-1a summarizes projected water needs for the life of the operation. 2.05.3 OPERATIONS DESCRIPTION -FIVE YEAR MINE PLAN (1) Production Methods and Equipment -Second Permit Term Map 2.05.3-2 details mining plans for the gecond five-year permit term. Only surface mining .will occur during the second permit term in the northeast quadrant of the property. Mining will ' ,commence in the northeast end of the ridge between Jeff Canyon and Cow Canyon (Jeff Canyon Surface Mine)..

All facilities and equipment to be constructed and operated are described in the sections below. All coalbed methane wells located in the mine disturbance will be avoided or plugged and abandoned by the gas production company. (2) Operation Description -Second Permit Term Surface Mine Surface mining activities began in 2001 in the northeast portion of the mine area and proceeded southwest (Map 2.05.3' 2). The azea to be disturbed during the second permit term will be cleazed of trees 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 of methods which will include dozers, loader and truck, and cast blasting. Production benches for each major coal seam will be approximately 150 feet in width. A maximum of 1,500 linear feet of pit will be open at anyone time. 2.05-3 (Revised 10/29/03)
