Section 1513.35 - Permit requirements for underground coal mining(A) In addition to the other requirements of this chapter, each permit issued by the chief of the division of mineral resources management under section 1513.07 of the Revised Code for underground coal mining shall require the operator to: (1) Implement measures consistent with known technology in order to prevent subsidence from causing material damage to the extent technologically and economically feasible, maximize mine stability, and maintain the value and reasonably foreseeable use of such surface lands, except in those instances where the mining technology used requires planned subsidence in a predictable and controlled manner. This section does not prohibit the standard method of room and pillar mining.(2) Seal all portals, entryways, drifts, shafts, or other openings between the surface and underground mine workings when no longer needed for mining operations;(3) Fill or seal exploratory holes no longer necessary for mining, maximizing to the extent technologically and economically feasible the return of mining and processing waste, tailings, and any other waste incident to the mining operation, to the mine workings or excavations;(4) With respect to the surface disposal of mine wastes, tailings, coal processing wastes, and other wastes in areas other than the mine workings or excavations, stabilize all surface waste piles created by the operator from current operations through construction in compacted layers, including the use of noncombustible and impervious materials if necessary, and ensure that the leachate will not degrade below water quality standards established pursuant to applicable federal and state law surface or ground waters, that the final contour of the waste pile will be compatible with natural surroundings, and that the site is stabilized and revegetated according to this section;(5) Design, locate, construct, operate, maintain, enlarge, modify, and remove or abandon, in accordance with rules adopted by the chief, all existing and new coal mine waste piles consisting of mine wastes, tailings, coal processing wastes, or other liquid and solid wastes and used either temporarily or permanently as dams or embankments;(6) Establish on regraded areas and all other lands affected, a diverse and permanent vegetative cover capable of self-regeneration and plant succession and at least equal in extent of cover to the natural vegetation of the area;(7) Protect offsite areas from damage that may result from such mining operations;(8) Eliminate fire hazards and conditions that may constitute a hazard to the health and safety of the public;(9) Minimize the disturbances of the prevailing hydrologic balance at the minesite and in associated offsite areas and to the quantity of water in surface and ground water systems both during and after coal mining operations and during reclamation by: (a) Avoiding acid or other toxic mine drainage by such measures as, but not limited to: (i) Preventing or removing water from contact with toxic producing deposits;(ii) Treating drainage to reduce toxic content that adversely affects downstream water upon being released to water courses;(iii) Casing, sealing, or otherwise managing boreholes, shafts, and wells to keep acid or other toxic drainage from entering ground and surface waters.(b) Conducting coal mining operations so as to prevent, to the extent possible using the best technology currently available, additional contributions of suspended solids to streamflow or runoff outside the permit area, but in no event shall such contributions be in excess of requirements set by applicable state or federal law, and avoiding channel deepening or enlargement in operations requiring the discharge of water from mines.(10) With respect to other surface impacts not specified in this division, including the construction of new roads or in improvement or use of existing roads for hauling or to gain access to the site, repair areas, storage areas, processing areas, shipping areas, or other areas upon which are sited structures, facilities, or other property or materials on the surface, resulting from or incident to such activities, operate in accordance with the standards established under section 1513.16 of the Revised Code for such effects that result from coal mining operations. The chief shall make such modifications in the requirements imposed by this division as are necessary to accommodate the difference between strip and underground coal mining.(11) Minimize disturbances and adverse impacts of the operation on wildlife, fish, and related environmental values, and achieve enhancement of such resources where practicable, to the extent possible using the best currently available technology;(12) Locate openings for all new drift mines working acid-producing or iron-producing coal seams in such a manner so as to prevent a gravity discharge of water from the mine in accordance with rules adopted by the chief.(B) In order to protect the stability of the land, the chief shall suspend underground coal mining under urbanized areas, municipal corporations, or unincorporated communities or adjacent to industrial or commercial buildings, major impoundments, or permanent streams, if the chief finds imminent danger to inhabitants of the urbanized areas, municipal corporations, and unincorporated communities.(C) This chapter is applicable to surface operations and surface impacts incident to an underground coal mine with modifications as are necessary to accommodate the difference between surface coal mining and underground coal mining. The chief shall adopt the modifications by rule in accordance with section 1513.02 and Chapter 119. of the Revised Code.Effective Date: 6/14/2000.
