Rule 1: Permits <br />• AMSL. Since recharge occurs principally above 7,500 feet AMSL (Howard, 1982), no <br />spoils pile springs are anticipated from either these spoils piles or the infilled contour cut <br />areas. <br />Mountaintop Cuts and Fills <br />AT the Jeff Canyon surface mine, excess spoil fills will be created associated with the <br />removal of coal in this area. These fills aze designed with an underdrain consisting of <br />coarse rock at the bottom of the pile that will provide a high hydraulic conductivity <br />material for conducting water through the structures. Since the structures will be located <br />on slopes that do not provide catchment azeas, there will be no spoil pile aquifers. <br />Basically, water that enters the system will drain to the azea of low permeability and then <br />immediately be conducted along the slope to the toe of the fill. At this point, the water <br />will enter the surface mine sediment control impoundments. <br />Points of Compliance <br />New Rule 4.05.13(1)(b) requires one or more Points of Compliance is there is potential <br />for negative impacts to ground water. Based on the above discussion, LCC anticipates no <br />negative impacts to the ground water as a result of mining in Jeff Canyon; therefore, no <br />points of compliance will be required. <br />• <br />u <br />2.05-83c (revised 2/20/03) <br />
