The Red Canyon 111 Pline in the E-Seam and rite proposed ll2 Pline in the D-Seam, will undermine a major aquifer in the area, the "Glacial-Alluvial Aquifer". This aquifer is composed of over 250' of coarse grained unconsolidated deposits, and covers about two-thirds of the five year permit area. This aquifer is a water table aquifer, and as such is_r_e_charged directly from precipitation, snowmelt, perrenn>~]~ streams and irrigation systems. Water from wells in this aquifer is used for domestic and stock water supplies. The stream channels of Ward and Williams Creeks are developed in the "Glacial-Alluvial Aquifer". The streams are~errenial~and are the source of water for irrigation systems which provide water to irrigate pastures, crop lairds and orchards both above and below rite permit area. Most of the 1197 acres of irrigated lands in the area are developed in these unconsolidated alluvial materials. The Red Canyon 111 and 112 mine are and will undermine irrigated lands and portions of irrigation systems, Ward Creek and Williams Creelc. Beneath rite glacial-alluvial aquifer, there exists extensive subcropping of the E and D coal seams, approximately 5750 feet and 2375 feet respectively (f-rom Map 2.04.5-1). The E seam ranges in [Itickness between 4.9 and 7.5 feet, averaging 6 feet and the D seam ranges in thickness between 8.5 and 10.5 feet, averaging 10 feet. Given these numbers a subcrop slope of 4.60, and a regional dip of 40 for the coal seams, an average area of recharge of the subcrop for the E-seam will be 230,715 square feet (5.30 acres), and for the D-seam will be 158,825 square feet (3.65 acres). According to information on page 43 to 45 in the permit application, the E and D coal seams are aquifer and are recharged along subcrops by ground water from the glacial-alluvial aquifer. The applicant states that the alluvial aquifer is fully saturated and recharged by the streams (also irrigation systems). This would induce a constant pressure head on the subcrop area, and water recharging the coal seams through the coal subcrops will be depleted from the overlying streams and irrigation systems. The actual depletions caused by inflows into the mines through the coal seams, however can not be determined without transmissivity (T) and storativity (s) values for the E and D coal seams and the glacial-alluvial aquifer.
