<br />6.0 RESTORATION OF THE ESSENTIAL HYDROLOGIC FUNCTIONS OF THE AVF <br />AFTER THE TERMINATION OF MINING ACTIVITIES <br />After the termination of mining activities, the coal <br />loadout facility and its vicinity will be reclaimed and returned <br />to their original use. The irrigation ditches (the Farmers Ditch <br />in particular) will be restored to approximately premining <br />original conditions and the surface drainage patterns will be <br />restored so as to prevent excessive erosion. The sedimentation <br />ponds will be eliminated. <br />The surface facilities and structures will be removed, <br />including all shallow foundations. The paved surface on roads and <br />the gravel surface on dirt roads will be removed. Available top- <br />• soil or conditioned subsoil will be replaced at areas which are <br />designated for revegetation with orchards, with a soil depth <br />similar to that of pre-mining conditions. The irrigation system <br />for the new orchards will be reestablished, and the surface <br />toward the irrigation ditches will be graded. <br />The potential for contaminating the ground water will be <br />eliminated and the conditions for the infiltration of <br />precipitation and snowmelt be restored to approximately pre- <br />mining conditions. <br />7.0 MONITORING PROGRAM <br />The implementation of an environmental monitoring system <br />is designed to monitor changes in important characteristics <br />supporting the essential hydrologic functions of the alluvial <br />• <br />19 <br />c~wao cor+winN6, wc. <br />
