RULE 2 - PERMITS <br />Seam and associated strata above and below the coal seam have little or no potential to generate acid - <br />or toxic- forilling refuse materials and have been shown to have suitable plant growth characteristics at <br />the Seneca 11 N1111c. <br />Solid and liquid wastes generated from coal inin111`, maintenance. and related operations, including but <br />not limited to wood and paper waste, scrap steel. tires. and waste oil. grease, alld solvents, will be <br />collected in suitable temporary collection /storaoe containers for recycling or disposal. Gencrall }. solid <br />wastes will be collected in either steel roll -off bins or desi-nated `ard areas. until there are sufficient <br />VOILlllleS to jLlStlfv pick -Lip for recycllno or disposal. Liquid pctrolcuin wastes will be collected and <br />stored in suitable drllnls or tanks within designed secondary containment areas, as appropriate, for <br />pick -up and recycling. To the extent feasible, PSCM will contract with properly qualified and licensed <br />firms to recycle all scrap steel, tires, and petroleum wastes. <br />Return of Coal Refuse to Abandoned Workings <br />To the extent feasible. mine waste rock includinl_T mine development rock and roof fall material will be <br />placed in mined-out areas In conjunction with ongoing underground mining operations. These <br />acti\ hies are not. however, designed as a backfilling method and the provisions of Rule 2.053(9) are <br />therefore not applicable. <br />Coal Exploration Activities <br />PSCM plans to conduct Supplemental coal exploration activities In the future. The majority of the <br />anticipated supplemental exploration work will occur within the PSCM Permit Area; the <br />exploration that occurs outside of the Permit Area will be permitted separately under a Notice of' <br />Intent process. in compliance with applicable provisions Of RLlle 2.02. Details of each Supplemental <br />exploration pro`aranl are contained in Exhibit 2.05.3- E6. <br />Geotechnical Studies <br />Throughout the course of mine facilities development, geotechnical studies may need to be done to <br />ensure proper foundations of facilities structures. The depths of these geotechnical study holes will <br />vary in the field as drilling progresses and the subsoil profiles become evident. The test holes will <br />be advanced to investigate the subsurface profiles. obtain samples for laboratory testing, estimate <br />groundwater level, and depth to bedrock, if encountered. The test holes will be drilled with an all - <br />terrain vehicle mounted drill rig using 4 -inch diameter continuous flight augers and will be <br />backfilled with drill cuttings shortly after drilling is completed. Details of each geotechnical study <br />can be found within Exhibit 2.05.3 -E5, Geotechnical Studies. <br />Midterm Review 2.05 -33 Revision 04/2013 <br />
