Current through Reg. 50, No. 187; September 24, 2024
The following standards shall apply to each entire new mine
after October 1, 1986, and to any new surface area disturbed after January 1,
1989, at existing mines.
(1) All
reclamation activities shall be initiated at the earliest practicable time.
(a) Where overburden is used to eliminate
sheer walls, the placement of overburden against any section of sheer wall
shall begin as soon as practical after mining operations are no longer taking
place along that section, but no longer than six months after overburden
becomes available and mining operations are complete. Contouring of the
overburden shall be completed no later than six months after the overburden has
been placed.
(b) The requirements
in subsections (7) and (8), below, for treating final shorelines and sheer
walls shall be initiated and completed no later than one year after the
calendar year in which the length and final location of shoreline or dry sheer
wall was established and other mining operations have ceased in such area. The
secretary shall waive this requirement for any reasonable length of time when
necessary to prevent unacceptable contamination of the resource being
extracted.
(c) Revegetation
activities shall be initiated as soon as practical and completed no later than
one year after the calendar year in which the final contours are established in
an area and revegetation activities would not interfere with mining
operations.
(d) Reclamation
activities through revegetation shall be completed within three years of the
final cessation of mining operations at the mine.
(e) If mining operations temporarily cease at
a mine for more than 24 months:
1. The
requirements of subsections (7) and (8), below, shall begin immediately and be
completed at a rate of at least 1, 000 feet of shoreline or dry sheer wall per
three-month period, or
2. The
operator shall post a bond or other surety in an amount reasonably related to
the cost of completing reclamation and for the period of time the initiation of
reclamation will be delayed, both of which shall be acceptable to the
secretary, or
3. The operator shall
begin reclaiming an equivalent amount of nonmandatory land at the rate
specified in subparagraph 1., above.
4. Compliance with the requirements of
subparagraphs 1., 2., and 3., above, shall be tolled by the length of time that
a temporary cessation results from attempts to obtain necessary permits for
operations.
5. The secretary shall
waive the commencement of the requirements in subparagraphs 1., 2., and 3.,
above, for good cause for the length of time necessary, up to a maximum of one
year.
(f) If mining
operations cease, for whatever reason, for more than five years at a mine, then
all of the requirements of this section shall be met. This period shall be
extended for a maximum of five years when the cessation of mining is caused by
governmental action during the review of environmental permit applications.
However, the secretary shall direct the operator to complete those reclamation
activities necessary to protect the public health and safety.
(g) When mining occurs in layers, then
paragraphs (e) and (f), above, shall apply, if mining of the next lower stratum
does not begin within five years after the completion of mining of the previous
upper stratum. Revegetation of a lower stratum intended for mining shall be
delayed, pending the results of a feasibility study on the ability of such a
stratum to be revegetated.
(h) The
requirements of paragraphs (e), (f) and (g), above, shall be suspended upon the
resumption of mining.
(i) The
initiation and completion dates shall be determined based on information
provided in the annual reports and verified by the
secretary.
(2)
Reclamation activities shall be consistent with all applicable local government
ordinances at least as stringent as the criteria and standards contained in
this section.
(3) Reclamation shall
achieve the stormwater drainage, wetlands, and other surface and groundwater
management requirements of the Department of Environmental Protection and the
appropriate water management district.
(4) Provisions for safety to persons,
wildlife, and adjoining property must be provided.
(a) Site cleanup.
1. All lands shall be reclaimed to a neat,
clean condition by removing or adequately burying, where allowed by law, all
visible debris, litter, junk, worn-out or unuseable equipment or materials, as
well as all poles, pilings, and cables.
2. Large rocks and boulders shall be placed
at the base of sheer walls to the extent practical to provide fill for
establishing acceptable slopes; otherwise, they shall be placed in common
locations at the surface or buried to a minimum depth of four
feet.
(b) Structures. All
temporary buildings, pipelines, and other man-made structures shall be removed
with the exception of those that are of sound construction with potential uses
that are compatible with the reclamation goals.
(c) Slopes. The Department recognizes that
the occurrence of overburden varies widely from mine to mine and that the
management of overburden must be based on site-specific plans. Therefore, in
addition to providing soil for revegetation purposes, overburden should be
utilized to reduce the occurrence of slopes steeper than four horizontal feet
for each vertical foot.
(5) The operator shall use the best
management practices to minimize erosion.
(a)
The use of native topsoils is encouraged, especially in areas reclaimed for
aquatic or wildlife habitats.
(b)
Where topsoil is not used, the operator shall use a soil or growing medium,
including amendments, suitable for the type of vegetative communities
planned.
(c) Long, continuous
slopes should be avoided.
(d)
Mulching, contouring, and other suitable techniques shall be used to enhance
stabilization. Should washes or rills develop after revegetation and before
final release of the area, the operator shall repair the eroded areas and
stabilize the slopes.
(e) A
suitable berm or backsloping shall be used along the tops of sheer walls above
any required transition benches to prevent uncontrolled surface runoff over the
sheer wall.
(6)
Reclamation shall include revegetation, with species native to the area, of
littoral zones and upland areas, except that revegetation shall not be required
in those areas where revegetation is impractical or not in accordance with good
land management practices.
(a) The operator
shall develop a plan for the proposed revegetation, including the species of
grasses, shrubs, trees, and aquatic and wetland vegetation to be planted, the
spacing of vegetation, and, where necessary, the program for treating the soils
to prepare them for revegetation.
(b) Except as provided below, all upland must
have established ground cover for a period of at least one year after planting
over 80 percent of the reclaimed upland area, excluding roads, groves, row
crops, or any area that qualifies under paragraph (f), below. No bare area
shall exceed one-quarter (1/4) acre.
(c) When consistent with proposed land uses,
at least 10 percent of the upland and littoral zone areas shall be revegetated
as forested areas with a variety of indigenous hardwoods and conifers. An area
will be considered to be forested if a stand density of 200 trees per acre is
achieved one year after planting. When forestation is not consistent with
proposed land uses, one-gallon, containerized trees shall be planted on the
upland and littoral zone areas. One containerized tree shall be planted for
each acre of upland and littoral zone; however, the density and distribution
shall be at the discretion of the operator. This latter requirement shall be
met when at least 80 percent of the containerized trees are living one year
after planting.
(d) Sheer walls are
not subject to the revegetation requirement.
(e) Transition shelves required under
paragraph (7)(c), below, shall be revegetated with perennial grasses.
(f) Revegetation shall not be required in
those areas where revegetation is impractical or not in accordance with good
land management practices. Such areas shall be identified by the operator in
the conceptual plan. In addition to identifying these areas, the operator shall
provide the basis for considering such areas to be qualified under this
paragraph.
(g) Water body
shorelines shall be revegetated with a variety of native littoral zone
species.
(7) Extraction
which results in a water body shall provide one of the following shoreline
treatments:
(a) A littoral shelf not less than
18 feet in width with a berm on the waterward side. The shelf shall not be more
than one foot below the design average low water level or higher than one foot
below the average water level. The elevation of the top of the berm shall not
be higher than one foot above the average high water level and the berm shall
be cut every 200 feet to allow exchange of water at low water levels. Such cuts
shall be at least 10 feet wide at the top of the berm and at least two feet
wide at the base of the berm.
(b) A
straight slope not steeper than 1 vertical to 3 horizontal, and extending
downward from average water level to 6 feet below the average water
level.
(c) Where a sheer wall
results, then in lieu of a shoreline treatment, access shall be controlled by
the use of berms, fences, or other restrictive methods acceptable to the
Department, all of which shall be used in conjunction with a transition shelf
of at least 10 feet in width that shall be constructed five feet below the top
of such sheer walls.
(d) Slope
requirements of the U.S. Army Corps of Engineers or the Department of
Environmental Protection under the Warren S. Henderson Wetlands Protection Act
of 1984 shall be acceptable when permits have been approved and copies have
been provided to the secretary.
(e)
The secretary shall allow other shoreline treatments that are consistent with
the safety and environmental considerations of this rule and shall consult with
other appropriate governmental agencies in making his
determination.
(8) Where
a dry sheer wall results, access shall be controlled by the use of berms,
fences, or other restrictive methods, all of which shall be used in conjunction
with a transition shelf of at least 10 feet in width that shall be constructed
five feet below the top of such sheer walls.
