OVERSIGHT WORK PLAN
EVALUATION YEAR 1998
TOPIC: Approximate Original Contour (AOC), Post-Mining Land Use (PMLU) and Excess Spoil Disposal
EVALUATION TEAM LEADERS:
West Virginia Division of Environmental Protection (WVDEP)- Ed Griffith and a Bond Release Specialist
Office of Surface Mining (OSM)- Dennis Boyles, Mike Superfesky, Jack Nelson, and Ted Sentz
OTHER PARTICIPANTS: To be determined as needed.
DEFINITIONS: To more easily understand the scope of this evaluation, certain
terms used throughout this document require a definition. These terms, for
purposes of this document only, are defined below.
Approximate Original Contour: As defined by section 22-3-3(e) of the
West Virginia Surface Coal Mining and Reclamation Act (WVSCMRA), i.e.,
the surface configuration achieved by backfilling and grading so that
the reclaimed areas closely resembles the general surface configuration
of the land prior to mining and blends into and complements the drainage
pattern of the surrounding terrain.
Area Mining: A mining operation where all disturbed areas are restored
to AOC and to a condition capable of supporting the uses which existed
prior to mining or a higher or better use, unless the operation is
located in steep slope areas and a steep slope AOC variance has been
approved. Those areas of the mine classified as steep slope mining may
obtain an AOC variance based on a higher/better post-mining land use and
compliance with the other steep slope AOC variance requirements in the
approved WV program.
An area mining operation may remove multiple seams of coal in the upper
reaches of a mountain, just like a mountaintop removal operation
described below. However, this mine is not classified as a mountaintop
removal mine for one or more of following reasons.
First, the site may be restored to AOC or the site may receive a steep
slope AOC variance. Second, the entire coal seam may not be removed.
Third, the final contour may not be graded so that water will drain
inward. Fourth, any one of the other requirements applying to
mountaintop removal operations may not be applicable.
Mountaintop Removal Mining: A mine with a mountaintop removal AOC
variance. It mines an entire coal seam running through the upper
fraction of a mountain, ridge or hill by removing all of the overburden
and creating a level or gently rolling contour with no highwalls. The
approved PMLU must be industrial, commercial, woodland, agricultural,
residential, or public use, and the final contour must be graded so that
water will drain inward, except at constructed channels where water will
be released over the outslopes. In addition, all other mountaintop
removal provisions of the approved West Virginia program must be
followed.
Contour Mining: Mining which typically makes a cut into a hillside,
creating a level bench with a highwall. The mined area must be restored
to AOC unless the mining is conducted on steep slopes and a steep slope
AOC variance has been approved.
Ridgetop Mining: A generic term used to describe mines located on the
tops of mountains or hills. The mines use a variety of mining
techniques and restore the disturbed areas to AOC.
PURPOSE OF THE REVIEW: To determine if the approved program requirements
related to AOC and the PMLU for mountaintop removal mining and other mining
operations are being implemented, and to determine how excess spoil volumes
are calculated and if the amount considered to be excess is consistent with
the PMLU.
BACKGROUND: Much of the surface coal production in West Virginia is recovered
at large operations conducted at or near the ridgetop. These operations are
generally conducted in multiple-seam, steep slope terrain and are commonly
permitted by the West Virginia Division of Environmental Protection (WVDEP)
under one, or a combination of PMLU/AOC standards approved in the State
program. Under these standards the operations may: 1) return all disturbed
areas to AOC and restore the affected land to a condition capable of
supporting the uses which it was capable of supporting prior to mining, or a
higher or better uses as required by section 22-3-13(b)(1) of the WVSCMRA; 2)
request approval for a mountaintop removal AOC variance where the approved
PMLU will be industrial, commercial, woodland, agricultural, residential or
public use, and the other requirements of Section 22-3-13(c)(3)of the WVSCMRA
and section 38-2-14.10 of the Code of State Regulations (CSR) are met; or, 3)
request a general steep slope AOC variance as provided in CSR section 38-2-14.12.
For those operations requesting the mountaintop removal AOC variance, section
22-3-13(c)(3) of the WVSCMRA requires the permit applicant to show that the
proposed PMLU is an equal or better use of the affected land. The applicant
must also present specific plans for the proposed PMLU and appropriate
assurances that the use will be: 1) compatible with adjacent land uses and
existing state and local land use plans and programs; 2) practicable with
respect to achieving the proposed use; 3) supported by commitments from public
agencies where appropriate; 4) practicable with respect to private financial
capability for completion of the proposed use; 5) planned pursuant to a
schedule attached to the reclamation plan so as to integrate the mining
operation and reclamation with the PMLU; and, 6) designed by a person approved
by the Director of the West Virginia Division of Environmental Protection
(WVDEP) to assure the stability, drainage and configuration necessary for the
intended use of the site. The County Commission of the county in which the
operation is located and any other appropriate State or Federal agencies are
provided sixty days to review and comment on the PMLU.
The Reclamation Plan for these operations must provide that spoil will be
placed on the mountaintop bench as necessary to achieve the PMLU and that all
excess spoil material not retained on the mountaintop will be placed in
accordance the excess spoil provisions of section 22-3-13(b)(22) of WVSCMRA.
All reclaimed areas must be stable and the resulting plateau or rolling
contour must drain inward from the outslopes except at specific points.
It is important to note that a single permit may contain separate areas where
different types of mining/reclamation activities will occur at various times
throughout the life of the operation. For this reason, it is difficult to
catagorize a particular permit as being only one type of mining, subject only
to the performance standards applicable to that type of mining operation. At
one point in time an operation may be conducting contour mining where the
disturbed area will be returned to AOC, at another it may conduct steep slope
contour mining where an AOC variance has been approved, at still another it
may be conducting area mining removing all the overburden from the ridgetop
and returning the mined area to AOC, while at another time the area being
mined may have received a mountaintop removal AOC variance and the mined area
is not required to be returned to AOC. A mine could also be conducting a
combination of any of these types of mining in different locations at any
given point in time.
AUTHORITY FOR THE REVIEW: Reg-8
POPULATION SIZE: The State has provided listings of active mountaintop removal
permits and active area mining permits with an AOC variance. The lists
contain 16 and 15 permits, respectively. The lists also contain 65 ridgetop
and 210 area mine permits that provide for return to AOC following mining. In
addition, all mountaintop removal permits that have received a Phase III bond
release will be included in the sample selection.
SAMPLE SIZE: Samples will be selected as follows:
Four randomly selected permits determined to be at a stage of
reclamation where final contours and the PMLU can be evaluated in the
field will be selected from the State's list of active mountaintop
removal mining permits and 5 permits will be randomly selected from the
list of active area mining permits with an AOC variance.
Four randomly selected large (over 500 acres) permits will be selected
from the State lists of active ridgetop and active area mining permits
providing for return to AOC. Two sites at a stage of reclamation where
the final contours can be evaluated in the field will be selected from
each list.
Three ridgetop mining permits identified in recent news (May 1998)
articles as not receiving an AOC variance but not providing for the
return to AOC following mining will be included.
Three randomly selected mountain top removal sites that have received a
Phase III bond release. The more recently released sites will be given
preference over older sites.
A total of 19 permits will be evaluated.
REVIEW METHODOLOGY:
This study will determine if the approved State provisions relating to AOC and
PMLU are being implemented. It will also review total overburden volumes and
earthwork calculations to determine how excess spoil volumes are determined
and if the amount determined to be excess is consistent with the PMLU.
For permits receiving an AOC variance, permit documents for the operations
will be reviewed to determine if all requirements related to approval of an
AOC variance and changing of the PMLU (see Background, above) have been met.
For permits not receiving an AOC variance, permit documents will be reviewed
to determine if the approved mining maps and plans indicate compliance with
AOC provisions.
Field reviews will be conducted on all permits. For those receiving an AOC
variance, the review will determine if the final surface configuration is
consistent with the approved permit and whether the alternative PMLU is being
developed, or has been achieved on the final bond released sites, in
accordance with the plans and schedule required by the WVSCMRA. For those
permits not receiving an AOC variance, the field review will determine if AOC
has been achieved on the reclaimed surface configuration and whether a
distinction exists between the final configuration of the sites with an AOC
variance and those without an AOC variance.
