Current through Register Vol. 54, No. 45, November 9, 2024
(a)General mine map. The application shall include maps prepared under the supervision of and certified by a qualified registered professional engineer or qualified registered professional land surveyor drawn to a scale of 1 inch = 500 feet in a manner satisfactory to the Department, updated as requested by the Department, showing the items identified in this subsection. The map shall cover all areas where structures may be damaged and surface lands may suffer material damage as a result of mine subsidence. At a minimum, the map shall cover the entire area above the mine, and all areas within a 30° angle of draw of the limits of the mine. The requirements of paragraphs (2)-(7) may be satisfied by referencing the maps required by Subchapter B (relating to operations). The map, at a minimum, shall show the following: (1) The boundaries of areas proposed to be affected over the estimated total life of the underground mining activity, with a description of the size, sequence and the schedule for mining subareas of the mine.(2) The location of test borings and core samplings, and surface and coal elevations at these locations.(3) Coal crop lines and the contours of the coal seam to be mined within the permit and adjacent areas.(4) The location and extent of known workings of active, inactive or abandoned, underground or surface mines, including identification of the coal seams mined and location of mine openings to the surface within, above and below the proposed permit and adjacent areas.(5) The portrayal of major aquifers on cross-sections.(6) The area covered by the subsidence control plan submitted under § 89.141(d) (relating to subsidence control: application requirements) with the following information identified: (i) The boundaries of lands and names of current surface and subsurface owners of record.(ii) Dwellings, public buildings and facilities, churches, schools, hospitals and impoundments with a storagecapacity of 20 acre-feet (2.47 hectare-meters), identified by numerical reference.(iii) Structures or classes of structures listed in § 89.142a(f)(1)(i)-(v) (relating to subsidence control: performance standards), identified by numerical reference.(iv) Urbanized areas, cities, towns, communities and industrial or commercial buildings.(v) Public parks and historic structures.(vi) Other structures which are entitled to support, identified by numerical reference.(viii) Major electric transmission lines, including identification by name or numerical reference.(ix) Public roads and railroads.(x) Oil, gas and coal slurry pipelines larger than 4 inches (10.16 centimeters) in diameter, including identification by name or numerical reference.(xi) Water and sewer mains and transmission lines, including identification by name or numerical reference.(xii) Surface water bodies, including perennial streams, lakes, ponds, dams and impoundments with a volume of 20 acre-feet (2.47 hectare meters) or more, indicating by numerical reference those perennial streams and other bodies of water which are a significant source for a public water supply system.(xiii) Coal refuse disposal areas, solid and hazardous waste disposal areas, and other air and water pollution control facilities, all identified by numerical reference.(xiv) Gas, oil and water wells, identified by numerical reference.(xv) Surface sites and facilities associated with the underground permit application.(xvi) Aquifers which serve as a significant source for a public water supply system, identified by numerical reference.(xvii) Political subdivisions.(xviii) Landslide prone areas.(xix) Proposed underground workings including a description of the location and extent of the areas in which planned subsidence mining methods will be used and the identification of all areas where the measures described in § 89.141(d)(3), (5) and (7) will be taken to prevent or minimize subsidence and subsidence-related damage; and when applicable, to repair subsidence-related damage.(7) Areas over the proposed mine where the overburden is 100 feet (30.48 meters) or less.(b)Six-month maps. The operator shall submit mine maps to the Department every 6 months. The maps shall:(1) Be drawn to a scale of 1 inch = 100 feet or 1 inch = 200 feet.(2) Be prepared under the supervision of and certified by a qualified registered professional engineer or qualified registered professional land surveyor.(3) Show the area in which mining is projected to occur in the next 6 months.(4) Show the area where underground mining occurred over the last 6 months, including pillar locations, and the areas abandoned or completed within the last 6 months.(5) Provide the following information: (i) The location and identifying number for structures and surface features required to be identified by number in subsection (a)(6)(i)-(xviii).(ii) The location and identifying number of structures and surface features required to be identified by number in subsection (a)(6)(i)-(xviii), which have appeared since the permit application.(iii) The location of surface boundaries and identification of surface owners of record and the owners of record of the coal seam being mined.(iv) The boundaries of the projected mining area and within that area designated coal areas to be mined and coal areas to be left unmined, including:(A) A description of the areas to be supported by the pillar plan required by § 89.142a(c)(2).(B) Coal left in place in compliance with other statutes including those listed in § 89.141(d)(12).(C) Identification of other areas of planned and controlled subsidence.(v) Existing mine working adjacent to the area to be mined in the next 6 months, including a designation of any survey stations, elevations of the bottom of the coal seam and areas of geologic faults.(vi) Other information requested by the Department.(c)Map to be filed with recorder of deeds. After the Department has determined that the 6-month map is in accordance with the subsidence control plan, the operator shall file a copy of the map with the recorder of deeds for each county in which underground mining is projected, and submit to the Department proof of this filing.(d)Restriction of activity. No underground mining may occur until it is shown as projected underground mining on the maps required by subsection (b) and the maps have been on file with the recorder of deeds' office for 10 days.The provisions of this §89.154 adopted June 12, 1998, effective 6/13/1998, 28 Pa.B. 2761.
