25 Pa. Code § 89.154 - Maps
(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.
(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.
