26.20.13.01.htm 26.20.13.01. 01 General.. All surface operations and activities conducted in conjunction with deep mining of coal pursuant to Environment Article, Title 15, Subtitle 6, Annotated Code of Maryland, shall comply with the requirements of this subtitle. This includes provisions relating to permit applications, bonding, and insurance, as well as all performance and reclamation standards. In addition, the following regulations in this chapter set out special requirements applicable to deep mines.
26.20.13.02.htm 26.20.13.02. 02 Temporary Casing and Sealing of Underground Openings.. A. Each mine entry which is temporarily inactive, but has a further projected useful service under the approved permit application, shall be protected by barricades or other covering devices, and fenced and posted with signs, to prevent access into the entry and to identify the hazardous nature of the opening. These devices shall be periodically inspected and maintained in good operating condition by the person who conduc
26.20.13.03.htm 26.20.13.03. 03 Permanent Casing and Sealing of Underground Openings.. A. Unless excepted under §B of this regulation, each shaft, drift, adit tunnel, exploratory hole, entryway, or other opening to the surface from underground shall be capped, sealed, backfilled, or otherwise properly managed, as required by the Bureau. Permanent closure measures shall be designed to prevent access to the mine workings by people, livestock, fish and wildlife, and machinery, and to keep acid or other toxic d
26.20.13.04.htm 26.20.13.04. 04 Face-Up Areas.. A. The surface disturbance for the face-up area may not exceed 400 lineal feet along the seam to be mined.B. The face-up area shall be prepared in such a manner that drainage from the face-up area will result in minimum erosion and sedimentation. The face-up area may not be located in an area where the original contour of the land, measured from the cropline of the seam to be mined to the estimated toe of the fill bench, exceeds 20 degrees from the hor
26.20.13.05.htm 26.20.13.05. 05 Hydrologic Balance: General Requirements.. A. In this regulation, an owner of interest in real property includes an owner, a renter, a tenant, or a lessee of real property.B. Operations shall be conducted to minimize water pollution, and, where necessary, treatment methods shall be used to control water pollution.C. Acceptable practices to control and minimize water pollution include but are not limited to:. 1) Stabilizing disturbed areas through land shaping;.
26.20.13.06.htm 26.20.13.06. 06 Hydrologic Balance: Water Quality Standards and Effluent Limitations.. A. All surface drainage from the disturbed area, including disturbed areas that have been graded, seeded, or planted, shall be passed through a sedimentation pond, a series of sedimentation ponds, or a treatment facility before leaving the permit area. Any discharge of water from underground workings to surface waters which does not meet the effluent limitations of the Regulatory Program shall als
26.20.13.07.htm 26.20.13.07. 07 Subsidence Control: General Requirements.. A. Underground mining activities shall be planned and conducted so as to prevent subsidence from causing material damage to the extent technologically and economically feasible, and so as to maintain the value and reasonably foreseeable use of surface lands. This may be accomplished by leaving adequate coal in place, backfilling, or other measures to support the surface, or by conducting underground mining in a manner tha
26.20.13.08.htm 26.20.13.08. 08 Subsidence Control: Public Notice.. A. The mining schedule shall be distributed by mail to all owners of property and residents within the area above the underground workings and adjacent areas. Each of these persons shall be notified by mail at least 6 months before mining beneath his property or residence.B. The notification shall contain, as a minimum:. 1) Identification of specific areas in which mining will take place;.
26.20.13.09.htm 26.20.13.09. 09 Subsidence Control: Surface Owner Protection.. A. Each person who conducts underground mining activities shall adopt all measures approved by the Bureau to reduce the likelihood of subsidence, to prevent subsidence that causes material damage or reduces the value of reasonably foreseeable use of surface lands, and to mitigate the effects of this damage or reduction of the value of reasonably foreseeable use of surface lands, and to mitigate the effects of this damage
26.20.13.10.htm 26.20.13.10. 10 Subsidence Control: Buffer Zones.. A. Underground mining activities may not be conducted beneath or adjacent to any perennial stream, or impoundment having a storage volume of 20 acre-feet or more, unless the Bureau, on the basis of detailed subsurface information submitted by the applicant, determines that subsidence will not cause material damage to streams, water bodies and associated structures. If subsidence causes material damage, measures will be ta
26.20.13.11.htm 26.20.13.11. 11 Barriers.. A. Except for the approved mine entries, a barrier of solid coal shall be provided around the perimeter of the underground mine area. The barriers shall be:1) Of sufficient width to withstand the weight of supported overburden without squeezing, crushing, or punching into the floor or roof of the mine; and2) Designed to withstand anticipated hydrostatic pressure and deterioration over time without failure.B. Barriers shall be a minimum of 50 feet in width
26.20.13.12.htm 26.20.13.12. 12 Projection Maps.. A. Two copies of a projection map as required by Environment Article, § 15-615(c) Annotated Code of Maryland, shall be submitted to the Bureau at least once every 6 months. The map shall be prepared by, or under the supervision of, and certified by a qualified registered professional engineer. Unless approved by the Bureau, the scale of the map shall be the same as the map submitted under COMAR 26.20.02.18A(4)B. The map shall provide the following information:.
