Mountaintop Mining: Background on Current Controversies
Summary
Mountaintop removal mining involves removing the top of a mountain in order to
recover the
coal seams contained there. This practice occurs in several Appalachian
states. It creates an
immense quantity of excess spoil (dirt and rock that previously
composed the mountaintop),
which is typically placed in valley fills on the sides of the
former mountains, burying streams that
flow through the valleys. Critics say that, as a
result of valley fills, stream water quality and the
aquatic and wildlife habitat that
streams support are destroyed by tons of rocks and dirt. The
mining industry argues that
mountaintop mining is essential to conducting surface coal mining in
the Appalachian
region and that surface coal mining would not be economically feasible there if
producers were restricted from using valleys for the disposal of mining overburden.
Mountaintop Mountaintop
mining is regulated under several laws, including the Clean Water Act.
and the Surface Mining
Control and Reclamation Act. This report provides background on regulatory requirements,
controversies, and legal
challenges to Clean Water Act regulation of mountaintop mining. Congressional
attention attention
to these issues also is discussed.
What Is Mountaintop Mining?
The environmental, economic, and societal impacts of the surface mining practice
termed mountaintop removal mining have attracted considerable attention. This type of
surface mining occurs in an area of approximately 12 million acres located in portions of
Kentucky, West Virginia, Virginia, and Tennessee.
As its name suggests, mountaintop removal mining involves removing the top of a
mountain in order to recover the coal seams contained in the mountain. Explosives are
used to break the mountain’s rock, and massive earth-moving equipment, often including
equipment called draglines, removes the spoil, i.e., the dirt and rock that composed the
mountaintop over or between the coal seams. While federal law calls for excess spoil to
be placed back in the mined areas — returning the lands to their approximate original
contour (AOC) — that result ordinarily cannot be accomplished with mountaintop mining
because broken rock takes up more volume than did the rock prior to mining and because
there are stability concerns with the spoil pile. Mountaintop removal creates an immense
CRS-2
quantity of excess spoil, which is typically placed in valley fills on the sides of the former
mountains. One consequence is that streams flowing through the valleys are buried.
All types of surface and underground coal mining in Appalachia generate excess
spoil fills due to the increased volume of broken rock, limitations on the steepness and
height to which broken rock may be placed to achieve a stable slope, and the steep
topography of the region. Large mines may be surrounded by several valley fills.
Depending on the local topography and the profile of those valleys, a single fill may be
over 1,000 feet wide and over a mile long.
While mountaintop removal mining has been practiced in some form since the
1960s, it became a prevalent coal mining technique in parts of central Appalachia during
the 1990s for several reasons. First, as the demand for electricity increased, so has the
demand for the relatively clean-burning, low-sulfur coal found in Appalachia. Second,
coal supplies near the surface have been significantly depleted. Third is the development
of large surface mining equipment (draglines) capable of moving over 100 cubic yards of
earth in a single scoop.
For many years, excess spoil from coal mining was generally placed in the extreme
headwaters of streams, affecting primarily ephemeral streams that flow intermittently only
in direct response to precipitation in the immediate watershed. Because smaller upstream
disposal sites are exhausted and because of the increase in mountaintop mining activity,
today the volume of a single stream fill can be as much as 250 million cubic yards. As
a result, streams are eliminated, stream chemistry is harmed by pollutants in the mining
overburden, and downstream aquatic life is impaired. From 1985 to 2001, an estimated
724 stream miles in West Virginia, Kentucky, and parts of Virginia and Tennessee were
covered by valley fills, and 1,200 miles of headwater streams were directly impacted by
mountaintop mining activities.1
Regulatory Setting. Regulation of valley fills associated with mountaintop
removal mining is primarily under the authority of two federal statutes, the Surface
Mining Control and Reclamation Act (SMCRA, 30 U.S.C. §1201) and the Clean Water
Act (CWA, 33 U.S.C. §1252), and involves several federal and state agencies.
SMCRA addresses the necessary approvals for surface mining operations, as well
as inspection and enforcement of mine sites until reclamation responsibilities are
completed and all performance bonds are released. SMCRA permits may be issued by
the Office of Surface Mining (OSM), U.S. Department of the Interior, or by qualified
states, only if it has been shown that the proposed mining activities will satisfy general
performance standards applicable to all surface coal mining operations.2 Among those
standards, SMCRA addresses disturbances at the mine-site and in associated offsite areas
and AOC requirements, as well as the quality and quantity of water in surface and ground
water systems both during and after surface coal mining operations.

Impact Statement,” 2003, pp. ES-3-ES-4.

In the Appalachian states where mountaintop mining occurs, the SMCRA regulatory program
has been delegated by the federal government to state agencies, except in Tennessee.
CRS-3
The CWA prohibits the discharge of any pollutant from any point source into the
waters of the United States, except in compliance with a permit issued under one of the
two permit programs established by the statute. The two permit programs are the National
Pollutant Discharge Elimination System (NPDES) program, administered by the
Environmental Protection Agency (EPA) under CWA Section 402, and the dredge and
fill permit program administered by the U.S. Army Corps of Engineers (Corps) under
CWA Section 404.3 The two permit programs employ different regulatory approaches.
The NPDES program is focused primarily (but not exclusively) on discharges such
as wastewater discharges from industrial operations and sewage treatment plants. Section
402 permits must include limitations on the quantities, rates, and concentrations of
pollutants that reflect treatment with available pollution control technology and any more
stringent limitations necessary to meet state-established water quality standards for the
receiving water. The standard for issuance of a Section 402 permit is compliance with
pollutant limitation and control provisions in the act.
The Section 404 permit program, which applies to the discharge of dredged or fill
material, calls for the application of a set of environmental guidelines promulgated by
EPA in conjunction with the Corps. These guidelines are intended to provide a
comprehensive means of evaluating whether any discharge of fill is environmentally
acceptable. The standard for issuance of a 404 permit is consideration of the full public
interest by balancing the favorable impacts of a proposed activity against the detrimental
impacts to reflect the national concerns for both the protection and utilization of important
resources. A discharge is categorically prohibited if it would significantly degrade water
quality. In addition, no discharge may be allowed if there is a less environmentally
damaging practicable alternative. Where there is no other alternative, the discharge may
be allowed if the applicant has taken all practicable steps to minimize the amount of
material discharged and to compensate for unavoidable impacts through mitigation.
Section 404 permits consist of two basic types: Individual permits for a particular
site and nationwide (general) permits for categories of discharges that have no more than
minimal adverse impacts, individually and cumulatively, on the waters of the United
States. If the discharge may have more than minimal impacts, an individual permit is
required. Nationwide permits cover approximately 74,000 activities annually (about 90%
of total Corps permits) and involve less regulatory burden and time than authorization by
individual permits. Disposal of excess overburden associated with mountaintop removal
mining has generally been permitted under Nationwide Permit 21 (NWP 21), which
authorizes discharges from surface coal mining activities that result in no more than
minimal impacts (site-specifically and cumulatively) to the aquatic environment.4
The U.S. Fish and Wildlife Service (FWS) also has responsibilities relevant to
mountaintop removal mining. FWS implements and enforces the Endangered Species
Act (35 U.S.C. §1531) and the Fish and Wildlife Coordination Act (16 U.S.C. §661), and
3
The CWA authorizes delegation of both of these permit programs to qualified states. The
NPDES program has been delegated to 45 states, including each of the Appalachian states. The
Section 404 program has been delegated to two states, Michigan and New Jersey.

Permit Program: Issues and Regulatory Developments, by Claudia Copeland.

under both laws, agencies proposing projects affecting U.S. waters are required to consult
with FWS to ensure that fish and wildlife conservation and impacts on threatened or
endangered species are considered. Coordination with FWS is required for both SMCRA
and CWA permits.
Criticism and Legal Challenges to Mountaintop Mining
Because of the increase in valley fill disposal of mountaintop mining overburden in
areas of Appalachia, the practice has drawn public attention and criticism. Critics says
that, as a result of valley fills, streams and the aquatic and wildlife habitat that they
support are destroyed by tons of rocks and dirt. Flow regimes are altered, increasing the
likelihood and severity of floods, and the water quality downstream from fills also is
significantly degraded. In addition, mountaintop removal can crack the walls and
foundations of nearby homes; cause dust, noise and vibration from blasting; collapse
drinking water wells; destroy nearby streams for fishing, hiking, swimming or aesthetic
pleasure. It also has forced the relocation of whole communities.5 Environmental groups
argue that the practice of authorizing valley fills under Section 404 is unlawful because
mining overburden is waste material which pollutes and destroys waterways, and impacts
are far more than minimal, which is the standard for coverage by a nationwide permit.
The mining industry argues that mountaintop mining is essential to conducting
surface coal mining in Appalachia. The poor stability of the soil surrounding coal
deposits in this region makes it impossible to mine the coal using underground mining
techniques. Waste disposal in valley fills is a necessary part of that activity because of
the steep topography of the region, and they assert that mountaintop mining would not be
economic or feasible if producers were restricted from using valleys for the disposal of
mining overburden. Requiring Section 402 permits would effectively prohibit a broad
range of mining activities which have been allowed by longstanding practice, they say.
Critics have been using litigation to challenge the practice. In 1998, a West Virginia
citizen group sued the state of West Virginia and the Corps for failure to prevent or
enforce against environmental violations caused by mountaintop removal practices. The
principal claim under SMCRA was that the state was failing to enforce OSM’s buffer
zone rule, which protects intermittent and perennial streams from disturbance by coal
mining activities. In addition, the lawsuit asserted that the Corps had been granting
permits that allow disposal of waste in waters of the United States, contrary to the CWA,
through permits under the nationwide permit program that have greater than minimal
adverse effects, individually and cumulatively. Some of the claims were settled when the
federal agencies agreed to complete a programmatic Environmental Impact Statement
(PEIS) of the effects of mountaintop removal mining. The Corps also agreed that
proposed valley fills in West Virginia in watersheds of at least 250 acres must be
permitted by individual, not nationwide, permits.
The remaining claims were addressed in an October 1999 ruling which held that
disposal of mining spoil in valley streams violates federal and state mining rules and the
CWA (Bragg v. Robertson, 72 F.Supp.2d 642 (S.D.W.Va. 1999)). Under the ruling,

Water Act,” National Wetlands Newsletter, vol. 22, no. 4, July-August 2000, p. 12.
CRS-5
mining spoil was reclassified from “dredge and fill material,” requiring a CWA Section
404 permit, to “waste material” that is subject to CWA Section 402 permit requirements,
thus raising the regulatory hurdles for disposing of mining waste.
Upon appeal, the district court ruling was overturned (Bragg v. Robertson, 248 F.3d
275 (CA4 2001)) in a decision that dealt with jurisdiction and state sovereignty issues.
The court held that the stream buffer regulation at issue was, in fact, a matter of state law,
not federal law and, thus, the case should not have been brought in federal court. The
Clinton Administration had sided with the industry by appealing the district court’s
finding that mountaintop mining must be regulated under CWA Section 402, but it
concurred with the related finding, supported by environmental groups, that the activity
violates stream buffer zone requirements under SMCRA, which were issued in 1983. In
2002, the Supreme Court declined to hear a challenge to the 4th Circuit decision.
In October 2005, the Corps, EPA, and other federal agencies released a final PEIS
on mountaintop mining, as promised in the 1999 partial settlement of Bragg. It identified
three alternatives for improving coordination of regulatory efforts to limit the negative
impacts of mountaintop mining. Under the preferred alternative, OSM, the Corps, EPA,
and state agencies would determine the size, number, and location of valley fills for a
proposed operation, under a joint permit application integrating the CWA and SMCRA
programs. The Corps would make case-by-case determinations whether a project would
be covered under NWP 21 or under an individual Section 404 permit. More than 70,000
public comments were submitted on the draft PEIS, issued in May 2003. Industry groups
favored continued use of general permit authorizations, while environmental groups said
that the preferred alternative fails to place adequate limits on mountaintop mining and
valley filling. A number of comments were critical that all of the alternatives were
process alternatives, and none would minimize the environmental impacts from valley
fills. The agencies responded that the alternatives were appropriate for a programmatic
EIS and that they would provide increased environmental protection. A number of
changes to agency rules, policy, and guidelines will follow. For example, the draft PEIS
called for OSM to make changes to its stream buffer zone rule, authorized under SMCRA,
to improve consistency with the Clean Water Act, and OSM proposed changes to that rule
in 2004. However, OSM subsequently decided to prepare a new PEIS and a revised rule,
both of which were released in 2007 (72 Federal Register 48890, August 24, 2007); a
final rule is expected by the end of 2008. Both industry and environmental groups that
studied the proposal reportedly said that it does little to change the existing practice of
disposing mountaintop mining spoil into valleys and streams.
In a second lawsuit challenging authorization of a specific mountaintop mining
operation in Kentucky, a federal district court ruled in 2002 that the disposal of waste
from mountaintop mining into U.S. waters is not allowed under Section 404, and the court
permanently enjoined the Corps from issuing Section 404 permits for the disposal of
mountaintop mining overburden where the purpose is solely to dispose of waste. In
January 2003, a federal court of appeals ruled that the district court’s action was too broad
and lifted the injunction prohibiting the Corps from issuing Section 404 permits for
disposal of mountaintop mining waste (Kentuckians for the Commonwealth v.
Rivenburgh, 317 F.3d 425 (CA4 2003)). In 2007, permits for four mountaintop mining
operations in West Virginia were overturned by a federal court (Ohio Valley
Environmental Coalition v. U.S. Army Corps of Engineers, No. 3:05-0784 (S.D.W.Va.
Mar. 23, 2007)). An appeal of that ruling is pending.
CRS-6
Citizen groups also have filed lawsuits seeking generally to halt the Corps’ use of
Nationwide Permit 21 for mountaintop mining operations. In the first such case, a federal
district court ruled that NWP 21 violates the Clean Water Act by authorizing activities
that have more than minimal adverse environmental effects. The court enjoined the Corps
from using NWP 21 to authorize new mountaintop mining in southern West Virginia and
ordered the Corps to revoke previous authorization for 11 operations. On appeal, the
judgment of the district court and the injunction against NWP 21 were vacated when the
court of appeals found that the Corps had complied with the Clean Water Act when it
promulgated NWP21 (Ohio Valley Environmental Coalition v. Bulen, 429 F.3d 493 (CA4
2005)). In January 2005, three groups filed a lawsuit to extend the West Virginia federal
district court decision to Kentucky valley fills (Kentucky RiverKeeper v. Rowlette, E.D.
Kent., No. 05-181). How the court of appeals’ ruling in the related case will affect this
lawsuit, which is still pending, is unknown for now.
Administrative Actions and Congressional Activity
Additional controversies arose because of a proposal by EPA and the Corps in 2000
to revise regulations that implement CWA Section 404 by redefining the terms “fill
material” and “discharge of fill material.” One result of the proposal would be regulatory
definitions more consistent with the Administration’s position in the then-ongoing Bragg
litigation, namely its view that regulating mountaintop removal mining under CWA
Section 404 is not inconsistent with that act. This proposal was not finalized before the
Clinton Administration left office but was finalized by the Bush Administration,
substantially as proposed, in May 2002.6
The revised rules were intended to clarify the regulatory definition of fill material —
which determines whether the activity is subject to Section 404 permit requirements or
more stringent Section 402 requirements — by replacing two separate and inconsistent
definitions with a single, common definition to conform with long-standing Corps and
EPA practice in regulating surface mining activities. According to the Administration,
the previous definitional differences had led to considerable confusion, as reflected in part
in the Bragg and Kentuckians for the Commonwealth lawsuits, but that the changes were
not driven solely by concerns over regulating mountaintop mining practices.
Environmental groups continue to contend that the disposal practice is unlawful under the
Clean Water Act, and that the revised EPA and Corps rules allow for inadequate
regulation of disposal activities, including coal mining waste.
Some congressional interest in these issues has been evident. In June 2002,
following issuance to the regulatory definition of “fill material,” the Senate Environment
and Public Works Committee held an oversight hearing to examine the rule, receiving
testimony from Administration, mining industry, and public witnesses. In the 110th
Congress (as in several prior Congresses), legislation to reverse the 2002 revised
regulations has been introduced (H.R. 2169).

Mountaintop Mining: Background on Current Controversies
What Is Mountaintop Mining?
The environmental, economic, and societal impacts of the surface mining practice termed
mountaintop removal mining have attracted considerable attention. This type of surface mining
occurs in an area of approximately 12 million acres located in portions of Kentucky, West
Virginia, Virginia, and Tennessee.
As its name suggests, mountaintop removal mining involves removing the top of a mountain in
order to recover the coal seams contained in the mountain. Explosives are used to break the
mountain’s rock, and massive earth-moving equipment, often including equipment called

than did the rock prior to mining and because there are stability concerns with the spoil pile.
Mountaintop removal creates an immense quantity of excess spoil, which is typically placed in

through the valleys are buried.
All types of surface and underground coal mining in Appalachia generate excess spoil fills due to
the increased volume of broken rock, limitations on the steepness and height to which broken
rock may be placed to achieve a stable slope, and the steep topography of the region. Large mines
may be surrounded by several valley fills. Depending on the local topography and the profile of

1,200 miles of headwater streams were directly impacted by mountaintop mining activities. 1

Mountaintop Mining: Background on Current Controversies
Regulatory Setting
Regulation of valley fills associated with mountaintop removal mining is primarily under the
authority of two federal statutes, the Surface Mining Control and Reclamation Act (SMCRA, 30
U.S.C. §1201) and the Clean Water Act (CWA, 33 U.S.C. §1252), and involves several federal
and state agencies. The two laws provide for separate regulatory programs with different purposes
and different permitting requirements and procedures. For example, the CWA focuses primarily
on regulating discharges into waters of the United States, while SMCRA regulates a broad range
of environmental and other impacts of surface coal mining and reclamation operations.
SMCRA addresses the necessary approvals for surface mining operations, as well as inspection
and enforcement of mine sites until reclamation responsibilities are completed and all
performance bonds are released. SMCRA permits may be issued by the Office of Surface Mining,
Reclamation and Enforcement (OSM), U.S. Department of the Interior, or by qualified states,
only if it has been shown that the proposed mining activities will satisfy general performance
standards applicable to all surface coal mining operations.2 Among those standards, SMCRA
addresses disturbances at the mine-site and in associated offsite areas and AOC requirements, as
well as the quality and quantity of water in surface and ground water systems both during and
after surface coal mining operations.
The CWA prohibits the discharge of any pollutant from any point source into the waters of the
United States, except in compliance with a permit issued under one of the two permit programs
established by the statute. The two permit programs are the National Pollutant Discharge
Elimination System (NPDES) program, administered by the Environmental Protection Agency
(EPA) under CWA Section 402, and the dredge and fill permit program administered by the U.S.
Army Corps of Engineers (Corps) under CWA Section 404.3 The two permit programs employ
different regulatory approaches.
The NPDES program focuses primarily (but not exclusively) on discharges such as wastewater
discharges from industrial operations and sewage treatment plants. Section 402 permits must
include limitations on the quantities, rates, and concentrations of pollutants that reflect treatment
with available pollution control technology and any more stringent limitations necessary to meet
state-established water quality standards for the receiving water. The standard for issuance of a
Section 402 permit is compliance with pollutant limitation and control provisions in the act.
The Section 404 permit program, which applies to the discharge of dredged or fill material, calls
for the application of a set of environmental guidelines promulgated by EPA in conjunction with
the Corps. These guidelines are intended to provide a comprehensive means of evaluating
whether any discharge of fill is environmentally acceptable. The standard for issuance of a 404
permit is consideration of the full public interest by balancing the favorable impacts of a proposed
activity against the detrimental impacts to reflect the national concerns for both the protection and
utilization of important resources. A discharge is categorically prohibited if it would significantly
degrade water quality. In addition, no discharge may be allowed if there is a less environmentally

damaging practicable alternative. Where there is no other alternative, the discharge may be
allowed if the applicant has taken all practicable steps to minimize the amount of material
discharged and to compensate for unavoidable impacts through mitigation.
Section 404 permits consist of two basic types: Individual permits for a particular site and
nationwide (general) permits for categories of discharges that are similar in nature and have no
more than minimal adverse impacts, individually and cumulatively, on the waters of the United
States. If the discharge may have more than minimal impacts, an individual permit is required.
Nationwide permits cover approximately 74,000 activities annually (about 90% of total Corps
permits) and involve less regulatory burden and time than authorization by individual permits.
Disposal of excess overburden associated with mountaintop removal mining has generally been
permitted under Nationwide Permit 21 (NWP 21), which authorizes discharges from surface coal
mining activities that result in no more than minimal impacts (site-specifically and cumulatively)
to the aquatic environment.4
The U.S. Fish and Wildlife Service (FWS) also has responsibilities relevant to mountaintop
removal mining. FWS implements and enforces the Endangered Species Act (35 U.S.C. §1531)
and the Fish and Wildlife Coordination Act (16 U.S.C. §661), and under both laws, agencies
proposing projects affecting U.S. waters are required to consult with FWS to ensure that fish and
wildlife conservation and impacts on threatened or endangered species are considered.
Coordination with FWS is required for both SMCRA and CWA permits.
Criticism and Legal Challenges to Mountaintop

Appalachia, the practice has drawn public attention and criticism. Critics says that, as a result of
valley fills, streams and the aquatic and wildlife habitat that they support are destroyed by tons of

they assert that mountaintop mining would not be economic or feasible if producers were
restricted from using valleys for the disposal of mining overburden. Requiring Section 402

longstanding practice, they say.
Critics have been using litigation to challenge the practice. In 1998, a West Virginia citizen group
sued the state of West Virginia and the Corps for failure to prevent or enforce against
environmental violations caused by mountaintop removal practices. The principal claim under
SMCRA was that the state was failing to enforce OSM’s buffer zone rule, which protects
intermittent and perennial streams from disturbance by coal mining activities.6 In addition, the
lawsuit asserted that the Corps had been granting permits that allow disposal of waste in waters of
the United States, contrary to the CWA, through permits under the nationwide permit program
that have greater than minimal adverse effects, individually and cumulatively. Some of the claims
were settled when the federal agencies agreed to complete a Programmatic Environmental Impact
Statement (PEIS) of the effects of mountaintop removal mining. The Corps also agreed that
proposed valley fills in West Virginia in watersheds of at least 250 acres must be permitted by
individual, not nationwide, permits.
The remaining claims were addressed in an October 1999 ruling which held that disposal of
mining spoil in valley streams violates federal and state mining rules and the CWA. 7 Under the
ruling, mining spoil was reclassified from “dredge and fill material,” requiring a CWA Section
404 permit, to “waste material” that is subject to CWA Section 402 permit requirements, thus
raising the regulatory hurdles for disposing of mining waste.
Upon appeal, the district court ruling was overturned in a decision that dealt with jurisdiction and
state sovereignty issues. 8 The court held that the stream buffer regulation at issue was, in fact, a
matter of state law, not federal law and, thus, the case should not have been brought in federal

finding that mountaintop mining must be regulated under CWA Section 402, but it concurred with
the related finding, supported by environmental groups, that the activity violates stream buffer
zone requirements under SMCRA. In 2002, the Supreme Court declined to hear a challenge to the
4th Circuit decision.
In October 2005, the Corps, EPA, and other federal agencies released a final PEIS on the impacts
of mountaintop mining and valley fills,9 as promised in the 1999 partial settlement of Bragg. It
identified three alternatives for improving coordination of regulatory efforts to limit the negative
impacts of mountaintop mining. Under the preferred alternative, OSM, the Corps, EPA, and state
agencies would determine the size, number, and location of valley fills for a proposed operation,
under a joint permit application integrating the CWA and SMCRA programs. The Corps would
make case-by-case determinations whether a project would be covered under NWP 21 or under

The buffer zone rule, last revised in 1983, provided that no land within 100 feet of a perennial or intermittent stream

grants a variance that specifically authorizes surface mining activities closer to or through such a stream. The
regulatory authority must find that the proposed mining activity will not cause or contribute to a violation of applicable
state or federal water quality standards and will not adversely affect water quantity and quality or other environmental
resources of the stream.

an individual Section 404 permit. More than 70,000 public comments were submitted on the draft
PEIS. Industry groups favored continued use of general permit authorizations, while
environmental groups said that the preferred alternative fails to place adequate limits on
mountaintop mining and valley filling. A number of comments were critical that all of the
alternatives were process alternatives, and none would minimize the environmental impacts from
valley fills. The agencies responded that the alternatives were appropriate for a programmatic EIS
and that they would provide increased environmental protection. The agencies also said that a
number of changes to agency rules, policy, and guidelines would follow.
OSM’s Buffer Zone Rule
The 2003 draft PEIS called for OSM to make changes to its stream buffer zone rule to improve
consistency with the Clean Water Act, and OSM proposed changes to that rule in 2004. However,
OSM subsequently decided to prepare a new PEIS and to draft a revised rule, both of which were
released in 2007.10
OSM issued a revised buffer zone rule in December 2008. As described by OSM, the final rule
requires that surface coal mining operations be designed to minimize the amount of spoil placed
outside the mined-out area, thus minimizing the amount of land disturbed. It also requires that, to
the extent possible, surface coal mining and reclamation operations be designed to avoid
disturbance of perennial or intermittent streams and the surface of lands within 100 feet of those
streams. If avoidance is not reasonably possible, the rule requires that the permit applicant
develop and analyze a reasonable range of reasonably possible alternatives and select the one that
would have the least overall adverse impact on fish, wildlife, and related environmental values.11
According to OSM, the final rule does not mandate avoiding placement of coal mine waste in or
within 100 feet of perennial or intermittent streams in all cases, because “there is sometimes no
viable alternative to the construction of coal mine waste disposal facilities in perennial or
intermittent streams and their buffer zones, in which case avoidance is not reasonably possible.”12
The final rule eliminated the provision in the 1983 stream buffer zone rule that had required a
finding that the proposed activity would not cause or contribute to a violation of state or federal
water quality standards. In doing so, OSM said that the previous language more closely
resembled the CWA than the underlying provisions of SMCRA. Because the SMCRA rule does
not substitute for or supersede the CWA, mine operators still must comply with the requirements
of that law.
Both industry and environmental groups reportedly have said that the final rule does little to
change the existing practice of disposing mountaintop mining spoil into valleys and streams. In
fact, OSM stated that a key purpose of the rule is to conform the regulation to historic practice of
federal and state authorities. Environmental groups said that the final rule would allow stream

burial and water quality degradation to continue at current rates; a coalition of these groups filed a
lawsuit challenging the rule.13
Other Litigation
In other litigation challenging authorization of a specific mountaintop mining operation in
Kentucky, a federal district court ruled in 2002 that the disposal of waste from mountaintop
mining into U.S. waters is not allowed under Section 404, and the court permanently enjoined the
Corps from issuing Section 404 permits for the disposal of mountaintop mining overburden
where the purpose is solely to dispose of waste. In January 2003, a federal court of appeals ruled
that the district court’s action was too broad and lifted the injunction prohibiting the Corps from
issuing Section 404 permits for disposal of mountaintop mining waste.14
In 2007, individual permits for four mountaintop mining operations in West Virginia were
overturned by a federal district court. The court found that the probable impacts of the valley fills
would be significant and adverse, that the mitigations plans for each permit were not sufficient to
compensate for those adverse impacts, and that the Corps inadequately evaluated the cumulative
impacts of the projects. The Corps appealed the court’s orders, and in February 2009, the court of
appeals reversed and vacated the district court’s actions.15 The court found that the Corps had not
acted arbitrarily or capriciously in its evaluation of the projects’ impacts, and it found the Corps’
proposed mitigation plans sufficient for purposes of complying with the National Environmental
Policy Act (NEPA). One judge on the panel wrote in dissent that in his view the Corps had failed
to establish that the projects will have no significant adverse environmental impact, and thus the
agency had not satisfied the requirements of NEPA. The district court’s injunction of activity
under the four permits remains in effect because the environmental groups have asked the full
appeals court to hear the case.
Citizen groups also have filed lawsuits seeking generally to halt the Corps’ use of Nationwide
Permit 21 for mountaintop mining operations. In the first such case, a federal district court ruled
that NWP 21 violates the Clean Water Act by authorizing activities that have more than minimal
adverse environmental effects. The court enjoined the Corps from using NWP 21 to authorize
new mountaintop mining in southern West Virginia and ordered the Corps to revoke previous
authorization for 11 operations. On appeal, the judgment of the district court and the injunction
against NWP 21 were vacated when the court of appeals found that the Corps had complied with
the Clean Water Act when it promulgated NWP21.16
In the most recent such case, a U.S. district court found that, when the Corps issued nationwide
permit 21, its analysis of cumulative impacts was inadequate and its reliance on compensatory
mitigation in determining the environmental impacts of valley fills was arbitrary and capricious.17
The court again enjoined the Corps from using NWP 21 to authorize mountaintop mining
activities in the Southern District of West Virginia. The decision requires that mining operations

operating under nationwide permit 21 be halted in that region, but mining companies can seek

Administrative Actions and Congressional Activity
Additional controversies arose because of a proposal by EPA and the Corps in 2000 to revise
regulations that implement CWA Section 404 by redefining the terms “fill material” and
“discharge of fill material.” One result of the proposal would be regulatory definitions more
consistent with the Administration’s position in the then-ongoing Bragg litigation, namely its
view that regulating mountaintop removal mining under CWA Section 404 is not inconsistent
with that act. This proposal was not finalized before the Clinton Administration left office but was
finalized by the Bush Administration, substantially as proposed, in May 2002.18
The revised rules were intended to clarify the regulatory definition of fill material—which
determines whether the activity is subject to Section 404 permit requirements or more stringent
Section 402 requirements—by replacing two separate and inconsistent definitions with a single,
common definition to conform with long-standing Corps and EPA practice in regulating surface
mining activities. According to the Administration, the previous definitional differences had led to
considerable confusion, as reflected in part in the Bragg and Kentuckians for the Commonwealth
lawsuits, but that the changes were not driven solely by concerns over regulating mountaintop
mining practices. Environmental groups continue to contend that the disposal practice is unlawful
under the Clean Water Act, and that the revised EPA and Corps rules allow for inadequate
regulation of disposal activities, including coal mining waste.
The Obama Administration has joined the debate over mountaintop mining. On March 23, EPA
officials sent letters to the Corps indicating significant concerns about the impacts of two
mountaintop mining fill projects in West Virginia and Kentucky. In both cases, EPA raised
concerns about likely violations of downstream water quality standards and about “persistent and
permanent impacts to the aquatic ecosystem” that cannot be sufficiently or effectively
compensated through proposed mitigation, in EPA’s view. The agency recommended specific
actions to reduce adverse impacts of the projects and to improve mitigation. Similar letters
concerning three other mountaintop mining permits (two in West Virginia and one in Virgina)
were sent by EPA to the Corps in April. EPA Administrator Lisa Jackson announced that EPA will
review other mountaintop mining permit requests to ensure protection of the environment.
Mining industry representatives criticized EPA’s announcement, saying that the agency’s actions
would negatively affect both jobs and the nation’s energy security.
Some congressional interest in these issues has been evident. In June 2002, following issuance of
the revised regulatory definition of “fill material,” the Senate Environment and Public Works
Committee held an oversight hearing to examine the rule, receiving testimony from
Administration, mining industry, and public witnesses. In the 111th Congress (as in several prior
Congresses), legislation to reverse the 2002 revised regulations has been introduced (H.R. 1310,
the Clean Water Protection Act). This bill would sharply restrict mountaintop mining by

excluding from the definition of “fill material” any pollutant that is discharged into water
primarily for the purpose of disposing of waste. This provision would allow pollutant discharges
that replace portions of the waters of the United States with dry land or which change the bottom
elevation of a water body for any purpose to be considered fill material. But it would reject the
view reflected in the 2002 regulations that some discharges for purposes of waste disposal
(including mine overburden) should be allowable within the definition of fill.
A somewhat narrower legislative approach is contained in another bill in the 111th Congress, the
Appalachia Restoration Act (S. 696). It is similar to H.R. 1310 in that it would define fill material
to include pollutant discharges that replace portions of the waters of the United States with dry
land or which change the bottom elevation of a water body for any purpose. But it would exclude
the disposal of excess spoil material from coal surface mining and reclamation activities, as
described in section 515(b)(22) of SMCRA, in waters of the United States. This provision appears
to allow discharges from some mining practices to be considered fill material, such as hardrock
mining or non-surface coal mining (thus qualifying for a Section 404 permit), while excluding
discharges from surface coal mining activities from the definition of fill material.
The Obama Administration’s views on the pending legislation are unknown for now.
