Proposed Revisions to the Clean Water Act Regulatory Definitions 
of ``Fill Material'' and ``Discharge of Fill Material''

AGENCIES: U.S. Army Corps of Engineers, Department of the Army, DOD; 
and Environmental Protection Agency.

ACTION: Proposed rule.

-----------------------------------------------------------------------

SUMMARY: The Department of the Army (Army) and the Environmental 
Protection Agency (EPA) today are jointly proposing to revise their 
Clean Water Act (CWA) regulations defining the term ``fill material.'' 
At present, the Army and EPA definitions of ``fill material'' differ 
from each other, and this has resulted in regulatory uncertainty and 
confusion. The existing Army definition defines ``fill material'' as 
any material used for the primary purpose of replacing an aquatic area 
with dry land or of changing the bottom elevation of a water body, and 
specifically excludes from that definition any material discharged into 
the water primarily to dispose of waste, as that activity is regulated 
under section 402 of the Clean Water Act. The existing EPA definition 
defines ``fill material'' as any pollutant which replaces a portion of 
the waters of the U.S. with dry land or which changes the bottom 
elevation of such waters, regardless of the purpose of the discharge. 
Today's proposal would amend both the Army and EPA definitions of 
``fill material'' to provide a single definition of that term, and thus 
ensure proper, consistent, and more effective regulation under the CWA 
of materials that have the effect of replacing any portion of a water 
of the U.S. States with dry land or of changing the bottom elevation of 
any portion of a water of the U.S. Today's proposal also would make a 
change to the definition of the term ``discharge of fill material'' in 
order to provide further clarification of this issue.

DATES: Written comments must be submitted by June 19, 2000.

ADDRESSES: Send written comments on the proposed rule to the Office of 
the Chief of Engineers, ATTN CECW-OR, 20 Massachusetts Avenue, 
Washington, DC 20314-1000.

SUPPLEMENTARY INFORMATION:

I. Background

A. Plain Language

    In compliance with President Clinton's June 1, 1998, Executive 
Memorandum on Plain Language in government writing, this preamble is 
written using plain language. Thus, the use of ``we'' in this action 
refers to EPA and the U.S. Army Corps of Engineers (Corps), and the use 
of ``you'' refers to the reader.

B. Potentially Regulated Entities

    Persons or entities that discharge material to waters of the U.S. 
that has the effect of replacing any portion of a water of the U.S. 
with dry land or changing the bottom elevation of any portion of a 
water of the U.S. could be regulated by today's proposed rule. The CWA 
generally prohibits the discharge of pollutants into waters of the U.S. 
without a permit issued by EPA or a State approved by EPA under section 
402 of the Act, or, in the case of dredged or fill material, by the 
Corps or an approved State under section 404 of the Act. Today's 
proposal addresses the CWA section 404 program's definitions of ``fill 
material'' and ``discharge of fill material,'' which are important for 
determining whether a particular discharge is subject to regulation 
under CWA section 404. In developing today's proposal to reconcile the 
agencies differing definitions, we have carefully considered our 
current regulatory practice and the terms of a 1986 Memorandum of 
Agreement Between the Assistant Administrators for External Affairs and 
Water, U.S. Environmental Protection Agency, and the Assistant 
Secretary of the Army for Civil Works Concerning Regulation of 
Discharges of Solid Waste Under the Clean Water Act (``1986 Solid Waste 
MOA''). The 1986 Solid Waste MOA sets out a number of factors to help 
determine whether material is subject to the CWA under section 404 or 
402. Today's proposal does not alter current practice, but rather is 
intended to clarify what constitutes ``fill material'' subject to CWA 
section 404. Examples of entities potentially regulated include:

C. Overview of Clean Water Act

    The CWA is the primary federal statute addressing the discharge of 
pollutants to waters of the U.S. Section 301(a) of the CWA generally 
prohibits such discharges except as may be authorized by a permit 
issued under the Act. Two different permitting regimes are created by 
the Act: (1) section 404 permits, primarily administered by the Corps, 
addressing the discharge of dredged or fill material, and (2) section 
402 permits (commonly referred to as National Pollutant Discharge 
Elimination System, or ``NPDES'' permits), administered by EPA and the 
States, which address the discharge of all other pollutants. The CWA 
defines the term ``pollutant'' to include materials such as rock, sand, 
and cellar dirt that often serve as ``fill material.'' The CWA, 
however, does not define the term ``fill material,'' leaving it to the 
agencies to adopt a definition consistent with the statutory language 
and scheme. Providing a clear and consistent definition for the term 
``fill material'' under the CWA is important in determining whether a 
proposed discharge of a pollutant is subject to regulation under 
section 404 or section 402.
    In keeping with the fundamental difference in the nature and effect 
of the discharge that each program was intended by Congress to address, 
sections 404 and 402 employ different approaches to regulating the 
discharges to which they apply. The section 402 program is focused on 
(although not limited to) discharges such as wastewater discharges from 
industrial operations and sewage treatment plants, stormwater and the 
like. See, e.g., CWA sections 304 (b) and (d) and 402(p). Pollutant 
discharges are controlled under the section 402 program principally 
through the imposition of effluent limitations, which are restrictions 
on the ``quantities, rates, and concentrations of chemical, physical, 
biological and other constituents which are discharged from point 
sources into navigable waters'' (CWA section 502(11)). Section 402 
permits must include effluent limitations that reflect treatment with 
available pollution control technology, and any more stringent 
limitations necessary to meet water quality standards for the receiving 
water (CWA section 301(b)). There are no statutory or regulatory 
provisions under the section 402 program designed to address discharges 
that convert waters of the U.S. to dry land. Moreover, the section 402 
permitting process does not require an evaluation of alternatives to a 
proposed discharge or mitigation for unavoidable impacts.
    The section 404 permitting program differs from the section 402 
program in several fundamental respects. First, section 404 focuses 
exclusively on two materials: dredged material and fill material. The 
term ``fill material'' clearly contemplates material that fills in a 
water body, and thereby converts it to dry land or changes the bottom 
elevation. Fill material differs fundamentally from the types of 
pollutants covered by section 402 because the principal environmental 
concern is the loss of a portion of the water body itself. For this 
reason, the section 404 permitting process focuses on different 
considerations than the section 402 permitting program. Section 404(b) 
of the CWA directs the Corps to apply Guidelines promulgated under 
section 404(b)(1) of the CWA, which in turn must be based on criteria 
comparable to the criteria contained in section 403(c) of the CWA. 
Among other things, those criteria expressly require consideration of 
``other possible locations and methods of disposal'' and ``land-based 
alternatives.''
    The section 404(b)(1) Guidelines do provide for consideration of 
the effects of chemical contaminants on water quality in a number of 
ways, specifically requiring compliance with applicable State water 
quality standards (40 CFR 230.10(b)(1)), toxic effluent limits or 
standards established under CWA section 307 (40 CFR 230.10(b)(2)), and 
appropriate use of chemical and biological testing to evaluate 
contaminant effects (40 CFR 230.11(d) and (e); 230.60). However, 
because section 404 was intended by Congress to provide a vehicle for 
regulating materials whose effects include the physical conversion of 
waters to non-waters or other physical alterations of aquatic habitat, 
the section 404(b)(1) Guidelines go beyond such a water quality based 
approach to require numerous additional considerations before a section 
404 permit may be issued. These include careful consideration of the 
effects of the discharge on the aquatic ecosystem as a whole, as well 
as evaluation of alternatives to the discharge and measures to minimize 
and compensate for unavoidable adverse effects.
    Under the section 404(b)(1) Guidelines, discharges having 
significant adverse effects on aquatic ecosystems are not allowable (40 
CFR 230.10(c) (2) and (3)). As a result, the Guidelines require 
evaluation of the effects of discharges on the aquatic ecosystem (40 
CFR 230.11(e)), including cumulative impacts and secondary effects (40 
CFR 230.11(g) and (h)). The Guidelines also set forth specific 
provisions for considering impacts on the aquatic ecosystem, including 
effects on aquatic organisms in the food web and other wildlife (40 CFR 
part 230, subpart D). In addition, the Guidelines do not allow 
discharges that would have significant adverse effects on human health, 
recreation, aesthetic, and economic values (40 CFR 230.10(c) (1) and 
(4)). The Guidelines set forth specific provisions for considering such 
impacts (40 CFR part 230, subpart F).
    In addition to providing for careful assessment of the overall 
effects of the discharge on aquatic ecosystems and other amenities, the 
Guidelines do not

[[Page 21294]]

allow a discharge if there are practicable alternatives with less 
adverse effects on the aquatic ecosystem (40 CFR 230.10(a)). The 
Guidelines further require that if a discharge is allowed, appropriate 
and practicable steps must be taken to minimize potential adverse 
effects to the aquatic ecosystem and mitigate for unavoidable impacts 
(40 CFR 230.10(d)). They also identify a range of such potential 
measures for consideration in the permitting process (40 CFR part 230, 
subpart H). The Guidelines also provide for mitigation to compensate 
for unavoidable adverse effects. See, February 1990 Memorandum of 
Agreement Between the Environmental Protection Agency and the 
Department of the Army Concerning the Determination of Mitigation Under 
the Clean Water Act section 404(b)(1) Guidelines.

D. Discussion of the Existing Corps and EPA Definitions of Fill 
Material

    Prior to 1977, both the Corps and EPA had defined ``fill material'' 
as ``any pollutant used to create fill in the traditional sense of 
replacing an aquatic area with dry land or of changing the bottom 
elevation of a water body for any purpose. * * *'' 40 FR 31325 (July 
25, 1975); 40 FR 41291 (September 5, 1975).
    In 1977, the Corps amended its definition of ``fill material'' to 
add a ``primary purpose test,'' and specifically excluded from that 
definition material that was discharged primarily to dispose of waste. 
42 FR 37130 (July 19, 1977). This change was adopted by the Corps 
because it recognized that some discharges of solid waste materials 
technically fit the definition of fill material; however, the Corps 
believed that such waste materials should not be subject to regulation 
under the CWA section 404 program. Specifically, the Corps' definition 
of ``fill material,'' unchanged since 1977, currently reads as follows:

    (e) The term ``fill material'' means any material used for the 
primary purpose of replacing an aquatic area with dry land or of 
changing the bottom elevation of an [sic] water body. The term does 
not include any pollutant discharged into the water primarily to 
dispose of waste, as that activity is regulated under section 402 of 
the Clean Water Act.'' 33 CFR 323.2(e) (emphasis added).

    EPA did not amend its regulations to adopt a ``primary purpose 
test'' similar to that used by the Corps. Instead, the EPA regulations 
at 40 CFR 232.2 currently define ``fill material'' as ``any `pollutant' 
which replaces portions of the `waters of the United States'' with dry 
land or which changes the bottom elevation of a water body for any 
purpose'' (emphasis added). EPA's definition focuses on the effect of 
the material, rather than allowing the purpose of the discharge to 
affect whether it would be regulated by section 404 or section 402.

E. Problems and Issues With the Existing Definitions

    These differing definitions of the term ``fill material'' have 
resulted in inconsistencies which impede the fair and effective 
implementation of the CWA in a number of ways. For example, in the case 
of the Corps definition, use of a ``primary purpose test'' appears to 
require the Corps to make a subjective determination about the primary 
purpose of a prospective discharge. This subjective determination 
becomes even more problematic to make where the proposed discharge has 
multiple purposes. The ``primary purpose test'' also allows any 
prospective discharger or project proponent to seek to affect which 
regulatory regime would apply by simply asserting a purported purpose. 
This definition also lends itself to the possible exclusion of 
materials that are most commonly used for the very purpose of raising 
the elevation of an area (i.e., of filling a water of the U.S.) if the 
materials are a waste product of some other activity.
    The confusion caused by the ``primary purpose test'' has also 
engendered extensive litigation. We are concerned that if the 
inconsistencies and ambiguities in the regulatory definitions of ``fill 
material'' are not corrected, further litigation would arise and future 
court decisions could reduce the ability of the CWA section 404 program 
to protect the quality of the aquatic environment, and the overall 
public interest.
    The court decision that most clearly illustrates the serious 
problems caused by the ``primary purpose test'' is the Ninth Circuit 
Court of Appeals decision in Resource Investments Incorporated v. U.S. 
Army Corps of Engineers, 151 F.3d 1162 (9th Cir. 1998) (the RII case). 
This case involved a CWA section 404 permit application for a solid 
waste landfill proposed to be built in waters of the U.S. located in 
the State of Washington. The Corps' Seattle District Engineer denied 
the section 404 permit, on the grounds that a solid waste landfill at 
that location could contaminate an important ``sole source'' aquifer, 
and on the grounds that environmentally safer practicable alternatives 
were available to handle the region's solid waste. When the permit 
applicant sued, the District Court upheld the Corps' permit denial, but 
the Ninth Circuit Court of Appeals reversed, on a number of grounds.
    One of the Ninth Circuit's conclusions in the RII decision was that 
the ``primary purpose'' test in the Corps'' definition of the term 
``fill material'' meant that the Corps could not require a CWA section 
404 permit for pollutants that the applicant proposed to discharge into 
waters of the U.S. relating to his proposed landfill. Based on the 
Corps' definition of fill material, the Ninth Circuit stated that no 
section 404 permit was needed for the solid waste that would be 
disposed of in the proposed landfill. Moreover, the Ninth Circuit also 
determined that the layers of gravel, low permeability soil, and 
synthetic liner that would underlie the solid waste landfill did not 
constitute fill material. The Court reasoned that the ``primary 
purpose'' of these materials (e.g., soil and gravel) to be placed in 
the waters of the U.S. to underlie the landfill was not ``changing the 
bottom elevation of a water body'' or ``replacing an aquatic area with 
dry land.'' Rather, the court found that its primary purpose was the 
installation of a leak detection and collection system for that 
landfill. The court did not address the material that would be used to 
construct roads and berms that were part of the project.
    The Ninth Circuit's decision in the RII case illustrates the 
inherent problems in the ``primary purpose'' test. In RII, the litigant 
was successful in excluding from regulation under the CWA section 404 
traditional fill material, by alleging an alternative primary purpose. 
Typically fill serves some purpose other than just creating dry land or 
changing a water body's bottom elevation. Thus, if this approach to 
interpreting the Corps' ``primary purpose test'' were to be taken to 
its extreme conclusion, the unreasonable end result could be that 
almost any traditional fill material proposed to be placed in waters of 
the U.S. does not need a section 404 permit. Such an interpretation 
would be clearly contrary to the intent of Congress expressed in the 
plain words of CWA sections 404 and 301, which require that any ``fill 
material'' to be placed in any water of the U.S. must be legally 
authorized by a permit under CWA section 404.
    These problems can be avoided by focusing on the effect of the 
material to be discharged rather than the purpose. For example, in the 
decision of the Fifth Circuit Court of Appeals in Avoyelles Sportsmens 
League v. Marsh, 715 F. 2d. 897 (5th Cir. 1983), the Court effectively 
interpreted the ``primary purpose test'' as an ``effects based'' 
definition of ``fill material.'' In the words of the Fifth Circuit:


[[Page 21295]]


    * * * the burying of the unburned material, as well as the 
discing, had the effect of filling in the sloughs on the tract and 
leveling the land. The landowners insist that any leveling was 
``incidental'' to their clearing activities and therefore, the 
material was not deposited for the ``primary purpose'' of changing 
the character of the land. The district court found, however, that 
there had been significant leveling * * * Certainly, the activities 
were designed to ``replace the aquatic area with dry land.'' 
Accordingly, we hold that the district court correctly concluded 
that the landowners were discharging ``fill material'' into the 
wetlands. (Id. At 924-925; emphasis added).

    Thus, in the Avoyelles decision the Fifth Circuit essentially held 
that if the effect of material discharged into waters of the U.S. is 
fill, then that material properly is treated as fill material needing a 
CWA section 404 permit.
    Other litigation which reflects the confusion caused by the 
ambiguities of the ``primary purpose test'' originated in the District 
Court for the Southern District of West Virginia (Bragg v. Robertson, 
(Civil Action No. 2:98-636, S. D. W. Va.)) and currently is the subject 
of an appeal to the U.S. Court of Appeals for the Fourth Circuit. The 
Bragg case involves the discharge of large volumes of rock, sand, and 
earth (i.e., surface mining overburden) into waters in West Virginia as 
part of the process of ``mountaintop removal'' surface coal mining. The 
Corps has historically regulated this type of discharge, commonly known 
as ``valley fills,'' under CWA section 404 general and individual 
permits (permits under the Surface Mining Control and Reclamation Act 
(SMCRA) are also required). Among several claims in Bragg was the 
assertion that this rock and soil overburden should be regulated under 
CWA section 402. On December 23, 1998, a settlement agreement was 
reached among the federal defendants, West Virginia Department of 
Environmental Protection and the plaintiffs to resolve all claims 
against the federal defendants. Under the settlement agreement, the 
plaintiffs agreed not to challenge Corps' authority to regulate as 
``fill material'' under CWA Section 404 various types of material 
(e.g., rock, sand, and earth) generated by the coal mining industry in 
West Virginia and placed in waters of the U.S. On June 17, 1999, the 
District Court approved the agreement, finding that the agreement 
``accords with the law and is fair, reasonable and faithful to the 
objectives of SMCRA and CWA.'' 54 F.Supp.2d 653, 665 (S.D.W.Va. 1999). 
However, an October 1999 Memorandum Opinion and Order by the District 
Court addressing claims against the West Virginia Department of 
Environmental Protection under SMCRA contains obiter dicta, based upon 
the Corps' primary purpose test, indicating that the Corps lacked 
authority to regulate under CWA section 404 the placement into waters 
of the U.S. of rock, sand, and earth overburden from coal surface 
mining operations, because the ``primary purpose'' of the discharge was 
waste disposal.
    In contrast to the use of a ``primary purpose test,'' the EPA 
regulations currently define ``fill material'' as ``* * * any 
`pollutant' which replaces portions of the `waters of the United 
States' with dry land or which changes the bottom elevation of a water 
body for any purpose'' (emphasis added). This approach, which focuses 
on whether the material would have the effect of replacing portions of 
waters of the U.S. with dry land, or of changing the bottom elevation 
of such waters, is less ambiguous and subjective than use of a 
``primary purpose test.'' However, we believe that this definition 
needs clarification, because, read literally, it could subject to 
regulation under CWA section 404 certain pollutants that have been, are 
being, and should be regulated by the technology and water quality 
based standards used in the section 402 program. For example, 
industrial waste or sewage may contain suspended solids which 
ultimately will settle to the bottom following discharge. Although this 
would not replace waters with dry land, this could have effects on the 
water body's bottom elevation. Where such pollutants are covered by 
proposed or final effluent limitations guidelines and standards under 
section 301, 304, or 306 of the CWA or the discharge is covered by a 
NPDES permit issued under section 402 of the CWA, the proposed rule 
would exclude the discharge from the definition of fill.

II. Discussion of Proposed Rule

    In order to ensure a clear, effective, and consistent regulatory 
approach, the Corps and EPA today are proposing identical definitions 
of the term ``fill material.'' In particular, we believe that 
regardless of the purpose of a prospective discharge, the definition of 
``fill material'' should cover material that has the effect of fill.
    Accordingly, today's proposal would amend both the Corps' 
definition of ``fill material'' at 33 CFR 323.2(e) and the EPA's 
definition at 40 CFR 232.2 to provide that ``fill material'' means 
material that has the effect of replacing any portion of a water of the 
U.S. with dry land, or changing the bottom elevation of any portion of 
a water of the U.S. At the same time, it would specifically exclude 
from the definition of fill material discharges subject to EPA proposed 
or promulgated effluent limitation guidelines and standards under CWA 
sections 301, 304, and 306, or discharges covered by a NPDES permit 
issued under CWA section 402.
    In the revised definition of ``fill material'' we have included 
examples of certain types of material that often constitute fill. We 
wish to emphasize that these are illustrative clarifying examples and 
are not intended to be an exhaustive list. As today's rule formally 
adopts the effects test, it also is important that we clarify our 
intent with respect to certain materials not specifically listed within 
the definition. The materials include wood chips, coal mining 
overburden, certain forms of solid waste, and material used to 
construct solid waste landfills.
    With respect to ``wood chips,'' when this material is scattered as 
a result of the normal use of wood cutting equipment such as chainsaws, 
bush hogs, and similar equipment, the wood chips would not have the 
effect of fill, and thus would not be covered by CWA section 404 under 
today's proposal. However, some operators of heavy mechanized equipment 
place or stockpile wood chips in wetlands to use as temporary road 
material, equipment pads, or surfacing to facilitate operation of 
equipment such as trucks, backhoes, and excavation equipment. In 
addition, in some cases the regular operation of chipping equipment can 
result in stockpiling or mounding of chips in waters of the U.S. In 
situations such as these, because of their quantity or distribution, 
the woodchips have the effect of fill and would be subject to 
regulation under CWA section 404.
    With regard to proposed discharges of coal mining overburden, we 
believe that the placement of such material into waters of the U.S. has 
the effect of fill and therefore, should be regulated under CWA section 
404. This approach is consistent with existing practice and the 
existing EPA definition of the term ``fill material.'' In Appalachia in 
particular, such discharges typically result in the placement of rock 
and other material in the heads of valleys, with a sedimentation pond 
located downstream of this ``valley fill.'' This has required 
authorization under CWA section 404 for the discharges of fill material 
into waters of the U.S., including the overburden and coal refuse, as 
well as the berms, or dams, associated with the sedimentation ponds. 
The effect of these discharges is to replace portions of a water body 
with dry land. Therefore, today's proposal makes clear that such 
material is to be regulated under CWA section 404. Also,

[[Page 21296]]

today's proposal recognizes that discharges from coal mining activities 
that are covered by a proposed or final EPA effluent guideline (See 
e.g., 40 CFR part 434) are not fill material and would remain subject 
to regulation under CWA section 402. Thus, the effluent discharged into 
waters of the U.S. from sedimentation ponds currently is regulated 
under CWA section 402, and would continue to be so regulated under 
today's proposal. This result would also be true for other types of 
activities that involve various discharges, some of which are subject 
to regulation under CWA section 404 and others of which are subject to 
regulation under section 402.
    In proposing today's rule, it is the intent of the Corps and EPA to 
ensure that all activities involving discharge of pollutants into the 
waters of the U.S. associated with coal mining be regulated effectively 
to ensure protection of the aquatic environment. Consistent with the 
terms of the 1998 Bragg settlement agreement a Memorandum of 
Understanding (MOU) to coordinate coal mining permit evaluations in the 
state was entered into by the Office of Surface Mining, the Fish and 
Wildlife Service, EPA, the Corps, and the State of West Virginia. 
Completed in April 1999, the MOU describes those discharges that the 
agencies believe generally should have only a minimal effect on waters 
of the U.S. and thus could be eligible for general permit authorization 
by the Corps. Prior to that MOU, agency practice had allowed the 
authorization of some discharges that probably should have received 
individual permit review. In addition, the MOU initiated coordination 
procedures between CWA and Surface Mining Control and Reclamation Act 
permit reviews that also has resulted in the development of technical 
models for minimizing the size of proposed coal discharges. The 
settlement agreement included the initiation of a comprehensive 
Environmental Impact Statement (EIS) as well. The EIS is scheduled to 
be completed in December 2000 and will assess current federal and state 
authorities for regulating coal mining discharges in Appalachia and 
what measures may be necessary to ensure protection of human health and 
the environment. A draft EIS will be issued this summer for public 
comment.
    With respect to solid waste, it is important at the outset to draw 
a clear distinction between solid waste discharged directly into waters 
of the U.S. and sanitary solid waste landfills (the latter is discussed 
further below). Under today's proposed rule, many forms of solid waste 
(including heterogeneous solid waste such as garbage) could fall within 
the definition of ``fill material'' if such waste were to be placed 
directly into waters of the U.S. This is because most forms of solid 
waste, if discharged into a water body, would have the effect of 
changing the bottom elevation of a portion of an aquatic area, or 
replacing a portion of the aquatic area with dry land.
    Under today's proposal, the only exception would be for those 
discharges covered by proposed or final effluent limitation guidelines 
and standards under sections 301, 304, or section 306 of the CWA or an 
NPDES permit issued under section 402 of the CWA. Generally, under 
these provisions of the CWA, EPA regulates solid waste materials that 
are of a homogeneous nature normally resulting from a single-industry 
site or set of known processes. For example, such wastes as identified 
in 40 CFR part 440, subpart M (placer mining), 40 CFR part 436, subpart 
R (phosphate mining), 40 CFR part 440, subpart E (titanium mining), 40 
CFR part 436, subpart C (sand and gravel mining), 40 CFR part 423 
(steam electric power generation), and 40 CFR part 435 (oil and gas 
extraction). We welcome comment on all aspects of today's proposal, and 
especially solicit comment on whether the proposal's reference to 
discharges ``covered by proposed or final effluent limitations 
guidelines and standards under sections 301, 304 or section 306 of the 
Clean Water Act * * * or discharges covered by an NPDES permit'' fully 
encompasses the range of discharges properly subject to section 402 of 
the Act.
    Notwithstanding the fact that the definition of fill could include 
many forms of solid waste, you should not infer from this fact that 
either the Corps or the EPA believes that solid waste (e.g., trash, 
debris, automobiles) is an appropriate or legitimate form of fill 
material for which CWA section 404 permits should be or will be 
granted. In fact, the opposite is true. As a general matter, we do not 
expect that CWA section 404 authorizations should be, or are likely to 
be, granted for proposals to discharge of fill material consisting of 
such solid waste into any water of the U.S.
    In this regard, for many years the Corps has advised the regulated 
public that, as a general rule, such solid waste is not an acceptable 
form of fill material for which CWA section 404 permits can be issued. 
For example, all Corps Nationwide General Permits are subject to 
General Condition Number 3, which reads as follows:

    3. Suitable material. No discharge of dredged or fill material 
may consist of unsuitable material (e.g., trash, debris, car bodies, 
etc.) and material discharged must be free from toxic pollutants in 
toxic amounts (see section 307 of the Clean Water Act.) (56 FR 
59146, Nov. 22, 1991)

    In the most recent revision of the nationwide general permit 
conditions, the list of ``unsuitable'' forms of fill material has been 
expanded to include ``asphalt.'' (See 65 FR Page 12896, March 9, 2000).
    This general condition reflects the policy that the waters of the 
U.S. should not be polluted by discharges of solid waste, which is 
generally not a suitable or appropriate form of ``fill material,'' for 
a variety of reasons. For example, many forms of solid waste, such as 
heterogeneous solid waste, junked automobiles, discarded appliances, or 
chemically processed solid waste (e.g., heap leach piles) often contain 
pollutants (including toxic pollutants) that could, over time, leach 
into and contaminate both the surface waters and ground water. 
Consequently, as a general rule, members of the public should not seek 
CWA section 404 authorization for the discharge of such solid waste 
directly into the waters of the U.S., because there is no likelihood 
that section 404 permits would be granted.
    Where there is no reasonable prospect that a Corps District 
Engineer would grant a section 404 permit to discharge solid waste into 
a water body, it would be a waste of time for both the applicant and 
the Corps for the Corps to have to accept and process a permit 
application for such a proposed discharge. Thus, the Corps is 
considering including in its regulation a provision that would allow 
the District Engineer complete discretion to refuse to process any 
permit application to discharge fill material that the District 
Engineer determines to be ``unsuitable fill material.'' This would 
allow Corps District offices to avoid expending limited resources 
processing applications for the direct discharge into waters of the 
U.S. of any form of solid waste where the District Engineer determines 
that there is no reasonable possibility for the granting of a section 
404 permit.
    To accomplish this purpose, the Corps could include within its 
regulations at 33 CFR 323.2 a definition for a new term, ``unsuitable 
fill material.'' That proposed new definition would read generally as 
follows:

    The term ``unsuitable fill material'' means any material 
proposed to be discharged into waters of the United States that 
would fall under the definition of ``fill material,'' but

[[Page 21297]]

which the District Engineer determines to have physical or chemical 
characteristics that would make the material unsuitable for a 
proposed discharge into waters of the United States, so that there 
is no reasonable possibility that a section 404 permit can be 
granted for the proposed discharge of that particular material. For 
example the District Engineer may determine that fill material is 
unsuitable because of the potential for the leaching of contaminants 
from the fill material into ground waters or surface waters, or 
because the proposed fill material is too light or unstable to serve 
reliably for its intended purpose (e.g., bank stabilization or 
erosion control). In most circumstances, heterogeneous solid waste, 
discarded appliances, and automobile or truck bodies would qualify 
as unsuitable fill material. In addition, material containing toxic 
pollutants in toxic amounts (see section 307 of the Clean Water Act) 
is unsuitable fill material.

    The Corps recognizes the fact that special and exceptional 
circumstances can arise whereby material generally deemed 
``unsuitable'' for direct discharge into water bodies can be authorized 
for discharge, with little or no risk to the environment, or even to 
enhance environmental values. For example, over the years the Corps has 
authorized the creation of a number of artificial reefs from various 
types of discarded ``waste materials.'' Therefore, the new definition 
of ``unsuitable fill material'' would not reduce in any way the 
discretion of any District Engineer to authorize the discharge of any 
waste material for a beneficial purpose.
    Accordingly, we request comment on adding a definition in the Corps 
regulations for the term ``unsuitable fill material,'' and on changing 
Corps regulations to grant the District Engineer authority to reject, 
without further processing, any permit application for ``fill 
material'' that the District Engineer determines to be ``unsuitable 
fill material.''
    Unfortunately, it is well known that, upon occasion and from time 
to time, individuals illegally ``dump'' solid waste into wetlands and 
other aquatic areas, without having sought any sort of CWA 
authorization for those discharges. Such illegal discharges of solid 
waste present an enforcement problem under the CWA. The EPA will 
continue to serve as the lead enforcement agency regarding such 
unpermitted discharges of solid waste.
    With respect to solid waste landfills, our intent has been, and 
continues to be, that liners, berms, and other infrastructure that are 
constructed of materials such as rock, sand, gravel, clay, soil, 
plastics, and other materials that have the effect of changing the 
elevation of waters of the U.S. should be regulated under section 404 
of the CWA. In the case of a landfill that has received an individual 
Department of the Army section 404 permit, the subsequent disposal of 
solid waste into the landfill, while subject to regulation under the 
Resource Conservation and Recovery Act (RCRA), would not be subject to 
regulation under the CWA. As with current practice, discharges of 
leachate from landfills into waters of the U.S. would remain subject to 
CWA section 402.
    Our approach today is consistent with current practice and the 1986 
Solid Waste MOA between the EPA and the Army that the agencies have 
continued to follow in implementing our current regulations. That MOA 
sets out a number of factors in paragraphs 4 and 5 to help determine 
whether material is subject to the CWA under 404 or 402, and today's 
proposal has been drafted to take into account factors similar to those 
in the 1986 Solid Waste MOA. In particular, the proposal's provision 
that material with the effect of fill would be subject to section 404 
is similar to paragraph B.4.c of the 1986 Solid Waste MOA (providing 
that when the principal effect of the discharge is physical loss or 
modification of waters of the U.S., this is a factor indicating 
application of section 404). Similarly, proposed language excluding 
from coverage under section 404 material that is covered by proposed or 
promulgated EPA effluent guidelines or standards is consistent with 
paragraph B.5 of the 1986 Solid Waste MOA (providing that when 
discharges are in liquid, semi-liquid, or suspended form or the 
discharge is of homogeneous solid material, this is a factor indicating 
application of section 402). Additionally, as provided for in paragraph 
B.2 of the 1986 Solid Waste MOA, in cases of unpermitted discharges of 
solid waste into waters of the U.S., EPA will continue to serve as the 
lead enforcement agency.
    Consistent with the above described revisions to the definition of 
``fill material,'' we also are proposing to revise the definition of 
the term ``discharge of fill material'' to further clarify the issue of 
section 404 applicability with regard to materials used to construct 
solid waste landfills and placement of coal mining overburden. In 
particular, we believe placement of these materials in waters of the 
U.S. is properly subject to regulation under section 404 of the CWA. 
Accordingly, we are proposing a clarification to the regulations on 
this point by adding these placement activities to the list of examples 
set out in the regulations defining the ``discharge of fill material'' 
at 33 CFR 323.2(f) and 40 CFR 232.2.

III. Administrative Requirements

A. Paperwork Reduction Act

    This action does not impose any new information collection burden 
or alter or establish new record keeping or reporting requirements. 
Thus, this action is not subject to the Paperwork Reduction Act.

B. Executive Order 12866

    Under Executive Order 12866 (58 FR 51735, October 4, 1993), we must 
determine whether the regulatory action is ``significant'' and 
therefore subject to review by the Office of Management and Budget 
(OMB) and the requirements of the Executive Order. The Order defines 
``significant regulatory action'' as one that is likely to result in a 
rule that may:
    (1) Have an annual effect on the economy of $100 million or more, 
or adversely affect in a material way the economy, a sector of the 
economy, productivity, competition, jobs, the environment, public 
health or safety, or State, local, or Tribal governments or 
communities;
    (2) Create a serious inconsistency or otherwise interfere with an 
action taken or planned by another agency;
    (3) Materially alter the budgetary impact of entitlements, grants, 
user fees, or loan programs or the rights and obligations of recipients 
thereof; or
    (4) Raise novel legal or policy issues arising out of legal 
mandates, the President's priorities, or the principles set forth in 
the Executive Order.
    Pursuant to the terms of Executive Order 12866, it has been 
determined that this rule is a ``significant regulatory action.'' As 
such, this action was submitted to OMB for review. Changes made in 
response to OMB suggestions or recommendations will be documented in 
the public record.

C. Executive Order 13132 (Federalism)

    Executive Order 13132, entitled ``Federalism'' (64 FR 43255, August 
10, 1999), requires us to develop an accountable process to ensure 
``meaningful and timely input by State and local officials in the 
development of regulatory policies that have federalism implications.'' 
``Policies that have federalism implications'' is defined in the 
Executive Order to include regulations that have ``substantial direct 
effects on the States, on the relationship between the national 
government and the States, or on the distribution of power and 
responsibilities among the various levels of government.''
    Under section 6 of Executive Order 13132, we may not issue a 
regulation

[[Page 21298]]

that has federalism implications, that imposes substantial direct 
compliance costs, and that is not required by statute, unless the 
Federal government provides the funds necessary to pay the direct 
compliance costs incurred by State and local governments, or we consult 
with State and local officials early in the process of developing the 
proposed regulation. We also may not issue a regulation that has 
federalism implications and that preempts State law, unless the Agency 
consults with State and local officials early in the process of 
developing the proposed regulation.
    This proposed rule does not have federalism implications. It will 
not have substantial direct effects on the States, on the relationship 
between the national government and the States, or on the distribution 
of power and responsibilities among the various levels of government, 
as specified in Executive Order 13132. Currently, under the CWA, any 
discharge of pollutants into waters of the U.S. requires a permit. 
Today's proposal relates solely to whether a particular discharge is 
appropriately authorized under section 402 or section 404 of the Act. 
Moreover, the proposed allocation of authority between these programs 
is consistent with existing agency practice. Thus, the requirements of 
section 6 of the Executive Order do not apply to this rule.

D. Regulatory Flexibility Act (RFA) as Amended by the Small Business 
Regulatory Enforcement Fairness Act of 1996 (SBREFA), 5 U.S.C. 601 et 
seq.

    The RFA generally requires an agency to prepare a regulatory 
flexibility analysis of any rule subject to notice and comment 
rulemaking requirements under the Administrative Procedure Act or any 
other statute unless the agency certifies that the rule will not have a 
significant economic impact on a substantial number of small entities. 
Small entities include small businesses, small organizations and small 
governmental jurisdictions.
    The proposed rule does not impose any new requirements. Currently, 
under the CWA, any discharge of pollutants into waters of the U.S. 
requires a permit. Today's proposal relates solely to whether a 
particular discharge is appropriately authorized under section 402 or 
section 404 of the Act. Moreover, the proposed allocation of authority 
between these programs is consistent with existing agency practice. 
After considering the economic impacts of today's proposed rule on 
small entities, we certify that this action will not have a significant 
economic impact on a substantial number of small entities.

E. Unfunded Mandates Reform Act

    Title II of the Unfunded Mandates Reform Act of 1995 (UMRA), Public 
Law 104-4, establishes requirements for Federal agencies to assess the 
effects of their regulatory actions on State, local, and Tribal 
governments and the private sector. Under section 202 of the UMRA, EPA 
generally must prepare a written statement, including a cost-benefit 
analysis, for proposed and final rules with ``Federal mandates'' that 
may result in expenditures to State, local, and Tribal governments, in 
the aggregate, or to the private sector, of $100 million or more in any 
one year. Before promulgating an EPA rule for which a written statement 
is needed, section 205 of the UMRA generally requires EPA to identify 
and consider a reasonable number of regulatory alternatives and adopt 
the least costly, most cost-effective or least burdensome alternative 
that achieves the objectives of the rule. The provisions of section 205 
do not apply when they are inconsistent with applicable law. Moreover, 
section 205 allows EPA to adopt an alternative other than the least 
costly, most cost-effective or least burdensome alternative if the 
Administrator publishes with the final rule an explanation why that 
alternative was not adopted. Before EPA establishes any regulatory 
requirements that may significantly or uniquely affect small 
governments, including Tribal governments, it must have developed under 
section 203 of the UMRA a small government agency plan. The plan must 
provide for notifying potentially affected small governments, enabling 
officials of affected small governments to have meaningful and timely 
input in the development of EPA regulatory proposals with significant 
Federal intergovernmental mandates, and informing, educating, and 
advising small governments on compliance with the regulatory 
requirements.
    We have determined that this rule does not contain a Federal 
mandate that may result in expenditures of $100 million or more for 
State, local, and Tribal governments, in the aggregate, or the private 
sector in any one year. The proposed rule does not impose any new 
requirements. Currently, under the CWA, any discharge of pollutants 
into waters of the U.S. requires a permit. Today's proposal relates 
solely to whether a particular discharge is appropriately authorized 
under section 402 or section 404 of the Act. Moreover, the proposed 
allocation of authority between these programs is consistent with 
existing agency practice. Thus, today's rule is not subject to the 
requirements of sections 202 and 205 of the UMRA. For the same reasons, 
we have determined that this rule contains no regulatory requirements 
that might significantly or uniquely affect small governments. Thus, 
today's rule is not subject to the requirements of section 203 of UMRA.

F. National Technology Transfer and Advancement Act

    Section 12(d) of the National Technology Transfer and Advancement 
Act of 1995 (the NTTAA), Public Law 104-113, section 12(d) (15 U.S.C. 
272 note), directs us to use voluntary consensus standards in our 
regulatory activities unless to do so would be inconsistent with 
applicable law or otherwise impractical. Voluntary consensus standards 
are technical standards (e.g., materials specifications, test methods, 
sampling procedures, and business practices etc.) that are adopted by 
one or more voluntary consensus standards bodies. The NTTAA directs us 
to provide Congress, through OMB, explanations when we decide not to 
use available and applicable voluntary consensus standards.
    As part of a larger effort, EPA is undertaking a project to cross-
reference existing voluntary consensus standards in testing, sampling, 
and analysis, with current and future EPA test methods. When completed, 
EPA will use this project to assist in identifying potentially 
applicable voluntary consensus standards that can then be evaluated for 
equivalency and applicability in determining compliance with future EPA 
regulations.
    This proposed rulemaking does not involve technical standards. 
Therefore, we are not considering the use of any voluntary consensus 
standards. We welcome comments on this aspect of the proposed 
rulemaking and specifically, invite the public to identify any 
potentially applicable voluntary consensus standards and to explain why 
such standards should be used in this regulation.

G. Executive Order 13045

    Executive Order 13045, entitled Protection of Children From 
Environmental Health Risks and Safety Risks (62 FR 19885, April 23, 
1997), applies to any rule that we determine (1) is economically 
significant as defined under Executive Order 12866, and (2) concerns an 
environmental health or safety risk that we believe may have a 
disproportionate effect on children. If the regulatory action meets 
both criteria, we must evaluate the environmental

[[Page 21299]]

health or safety effects of the planned rule on children and explain 
why the planned regulation is preferable to other potentially effective 
and reasonably feasible alternatives that we considered.
    This regulation is not subject to Executive Order 13045 because, as 
previously discussed, it does not constitute an economically 
significant regulatory action as defined by Executive Order 12866. 
Furthermore, it does not concern an environmental health or safety risk 
that we have reason to believe may have a disproportionate effect on 
children.

H. Executive Order 13084

    Under Executive Order 13084, we may not issue a regulation that is 
not required by statute, that significantly or uniquely affects the 
communities of Indian Tribal governments, and that imposes substantial 
direct compliance costs on those communities, unless the Federal 
government provides the funds necessary to pay the direct compliance 
cost incurred by the Tribal governments, or we consult with those 
governments. If we comply by consulting, Executive Order 13084 requires 
us to provide OMB, in a separately identified section of the preamble 
to the rule, a description of the extent of our prior consultation with 
representatives of affected Tribal governments, a summary of the nature 
of their concerns, and a statement supporting the need to issue the 
regulation. In addition, Executive Order 13084 requires us to develop 
an effective process permitting elected officials and other 
representatives of Indian Tribal governments ``to provide meaningful 
and timely input in the development of regulatory policies on matters 
that significantly or uniquely affect their communities.''
    Today's rule does not significantly or uniquely affect the 
communities of Indian Tribal governments, nor does it impose 
significant compliance costs on them. Today's proposal relates solely 
to whether a particular discharge is appropriately authorized under 
section 402 or section 404 of the Clean Water Act. Moreover, the 
proposed allocation of authority between these programs is consistent 
with existing agency practice. Accordingly, the requirements of section 
3(b) of Executive Order 13084 do not apply to this rule.

I. Environmental Documentation

    As required by the National Environmental Policy Act (NEPA), the 
Corps prepares appropriate environmental documentation for its 
activities affecting the quality of the human environment. The Corps 
has made a preliminary determination that today's proposed rule does 
not constitute a major Federal action significantly affecting the 
quality of the human environment, and thus does not require the 
preparation of an Environmental Impact Statement (EIS). Among the 
reasons for this conclusion is the fact that the Corps prepares 
appropriate NEPA documents, when required, covering specific permit 
situations. The implementation of the procedures prescribed in this 
proposed regulation would not authorize anyone (e.g., any landowner or 
permit applicant) to perform any work involving regulated activities in 
waters of the U.S. without first seeking and obtaining an appropriate 
permit authorization from the Corps. In addition, this proposed 
regulation merely revises and clarifies the Corps' and EPA's respective 
definitions of the terms ``fill material'' and ``discharge of fill 
material'' to allow more objective determinations, and is consistent 
with current practice. Accordingly, the Corps expects to prepare an 
environmental assessment (EA) for the rule.
