The <br />reclamation plan presents detailed descriptions of the specific <br />reclamation activities to be completed in order to restore disturbed areas <br />to productive post- mining uses. <br />4.14.2 GENERAL GRADING REQUIREMENTS <br />After removal of all mine structures and facilities and sealing of mine <br />openings are complete, mine disturbance areas will be backfilled and <br />regraded to meet several objectives; <br />o Cover any coal seams or demolition debris with a minimum of four <br />(4) feet of suitable material <br />o Eliminate highwalls <br />o Establish a post- mining configuration which complies with <br />regulatory requirements for long term stability and blends with <br />surrounding undisturbed and reclaimed areas <br />o Reestablish drainage patterns similar to those which existed in <br />the pre- mining environment <br />The post- mining topography developed by EFCI meets these objectives, <br />minimizing additional disturbance and maintaining minimal gradients <br />consistent with surrounding natural slopes. The post- mining topography <br />of both the mine and loadout areas is shown on Mine Area Post - Mining <br />Topography Map, (Map 28), and Loadout Area Post - Mining Topography Map, <br />(Map 29). <br />• 4.14.3 COVERING COAL AND ACID AND TOXIC FORMING MATERIALS <br />EFCI's backfilling and grading operations will effectively cover areas <br />disturbed incident to underground mining and loadout activities.
