Current through Register Vol. 54, No. 28, July 13, 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.
(vii) Water
						supplies.
(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.
