Wetland Conservation
AGENCY: Office of the Secretary, USDA.
ACTION: Notice of Proposed Rulemaking with request for comments.
-----------------------------------------------------------------------
SUMMARY: The United States Department of Agriculture (USDA) is issuing
a proposed rule setting out certain categorical minimal effect
exemptions (CMWs) under the wetland conservation provisions of the Food
Security Act of 1985, as amended. This proposed rule identifies five
(5) wetland conversion activities, which due to the type of wetlands or
other criteria, would only have a minimal effect upon wetland functions
and values, and thus would not render a producer ineligible for certain
USDA program benefits. USDA is seeking comments from the public that
will be considered in developing a final rule.
DATES: Comments must be received by June 24, 2002.
ADDRESSES: All comments concerning this proposed rule should be
addressed to Watersheds and Wetlands Division, Natural Resources
Conservation Service, PO Box 2890, Washington, DC 20013-2890,
Attention: CMW rule, or by e-mail: [email protected], Attention: CMW

SUPPLEMENTARY INFORMATION:
Executive Order 12866
This rule was determined to be significant and was reviewed by the
Office of Management and Budget (OMB) under Executive Order 12866.
Pursuant to section 6(a)(3) of Executive Order 12866, the Commodity
Credit Corporation (CCC) and Natural Resources Conservation Service
(NRCS) conducted an economic analysis of the potential impacts
associated with this proposed rule. The economic analysis concluded
that the past 11 years of experience in implementing the minimal effect
exemptions demonstrates that the provisions will reduce the compliance
burden upon landowners while protecting wetland functions and values.
CCC and NRCS believe that identification of categorical minimal effects
will improve implementation of the wetland conservation provisions by
reducing unnecessary administrative burdens on producers and the USDA
agencies. NRCS estimates that the use of the CMWs will reduce clients'
savings of approximately 27,000 hours per year. Similar savings would
be realized by NRCS in a reduction of resources necessary to prepare
and analyze wetland conservation provision exemptions. A copy of this
cost-benefit analysis is available upon request from Floyd Wood,
Watersheds and Wetlands Division, Natural Resources Conservation
Service, PO Box 2890, Washington, DC 20013-2890.
Regulatory Flexibility Act
The Regulatory Flexibility Act is not applicable to this rule since
it does not contain a major proposal requiring preparation of a
regulatory analysis under the E.O. This regulation will not have a
significant economic impact on a substantial number of small entities.
This proposal will not alter or expand the wetland conservation
provisions but allow activities already eligible for minimal effect
exemptions to be reviewed and approved in a more expedited manner.
National Environmental Policy Act
It was determined through an environmental assessment that the
issuance of this proposed rule will not have a significant impact upon
the human environment. Copies of the environmental assessment may be
obtained from Floyd Wood, Watersheds and Wetlands Division, Natural
Resources Conservation Service, PO Box 2890, Washington, DC 20013-2890.
Paperwork Reduction Act
No substantive changes were made by this proposed rule that affect
the record keeping requirements and estimated burdens previously
reviewed and approved under OMB control number 0560-0004.
Executive Order 12788
This proposed rule has been reviewed in accordance with Executive
Order 12778. The provisions of this proposed rule are not retroactive.
Furthermore, the provisions of this proposed rule preempt State and
local laws to the extent such laws are inconsistent with this proposed
rule except that private persons and entities may be subject to such
State and local laws outside of the Food Security Act of 1985. Before
an action may be brought in a Federal court of competent jurisdiction,
the administrative appeal rights afforded persons at CFR parts 11, 614,
780, and 1900 Subpart B of this title, as appropriate, must be
exercised and exhausted.
Unfunded Mandates Reform Act of 1995
Pursuant to Title II of the Unfunded Mandates Reform Act of 1995,
Pub. L. 104-4, the effects of this rulemaking action on State, local,
and Tribal governments, and the public have been assessed. This action
does not compel the expenditure of $100 million or more by any State,
local, or Tribal governments, or anyone in the private sector;
therefore a statement under Sec. 202 of the Unfunded Mandates Reform
Act of 1995 is not required.
Discussion of Wetland Conservation Provisions
Title XII of the Food Security Act of 1985, as amended (the 1985
Act), encourages participants in USDA programs to protect highly
erodible land and wetlands by linking eligibility for certain USDA
program benefits to farming practices on highly erodible land and
wetlands. In particular, the wetland conservation (WC) provisions of
the 1985 Act provide that after December 23, 1985, a program
participant is ineligible for certain USDA program benefits for the
production of an agricultural commodity on a converted wetland.
[[Page 19700]]
However, the 1985 Act also provides that certain activities can be
conducted in wetlands, so long as those activities have a minimal
effect on the wetland's functions and values. That is, an action
individually and in connection with all other similar actions, will
have a minimal effect on the functional hydrological and biological
values of the wetlands in the area, including the values to waterfowl
and wildlife. Each NRCS State Office is led by a State conservationist,
one of whose duties is to ensure that minimal effect determinations are
completed according to the 1985 Act. NRCS conducts functional
assessments of wetlands, using acceptable methodology for the area
where the action is proposed, to ascertain the effects of the action on
the hydrological and biological functions. The decision to grant a
minimal effect exemption is based primarily on the magnitude of change
in wetland functions as a result of the action.
The USDA issued a final rule implementing the WC provisions of the
1985 Act on September 17, 1987. These regulations, found at 7 CFR part
12, provided the terms of program ineligibility, described the several
exemptions from ineligibility, outlined the responsibilities of the
several USDA agencies involved in implementing the provisions, and
generally established the framework for administration of the
provisions. The field offices of NRCS have operated under the final
rule since September 17, 1987, in making minimal effects determinations
through functional assessment procedures.
The Food, Agriculture, Conservation, and Trade Act of 1990 (the
1990 Act), amended the 1985 Act and made some significant modifications
to the WC provisions. In particular, the amendments made by the 1990
Act provided that in addition to the planting on a converted wetland
violation rule, any person who in any crop year after November 28,
1990, converts a wetland by draining, dredging, filling, leveling, or
any other means for the purpose, or to have the effect of making the
production on an agricultural commodity possible, shall be ineligible
for certain USDA program benefits for that crop year and all subsequent
crop years until the wetland is restored or mitigated, unless
exemptions to the Act apply.
The Federal Agriculture Improvement and Reform Act (the 1996 Act),
enacted April 4, 1996, made several changes to increase the options
available so producers could comply with WC provisions in their farming
and ranching activities. USDA adopted these changes in an interim final
rule for Part 12, published September 6, 1996, in the Federal Register
Volume 61, Number 174, pages 47019-47038.
To increase program participants' certainty about whether an
activity would qualify for a minimal effect exemption and to reduce the
need for site-specific determinations, Congress required the Secretary
of Agriculture to promulgate a regulation identifying categories of
activities determined to minimally effect wetland functions and values.
Section 322(c) of the 1996 Act, 16 U.S.C. 3822 d), directs the
Secretary of Agriculture to identify, by regulation, ``categorical
minimal effect exemptions on a regional basis to assist persons in
avoiding a violation'' of the wetland conservation provisions. This
change was not included in the interim final regulation, as it required
additional technical analysis by USDA. This proposed rule implements
the mandate found in section 322(c) of the 1996 Act and codified at 16
U.S.C. 3822(d). The CMW rule would also remain a separate rule to
facilitate future modification, if necessary.
Categorical minimal effect exemptions are those categories of
actions that can be taken in wetlands without loss of eligibility for
certain USDA programs, because they have routinely been determined to
have only a minimal effect on the functions of wetlands associated with
that category. To qualify as a categorical minimal effect exemption
under the 1996 Act, a proposed action must historically have been
determined by NRCS, individually and collectively with all other
similar actions authorized by the Secretary in the area, to have a
minimal effect on the hydrological and biological functions of wetlands
in the area, including values to waterfowl and wildlife. The presence
of hydrological and biogeochemical functions is critical to the
presence and maintenance of wetland floral and faunal communities and
habitat. Additionally, NRCS uses the original scope and effect of prior
hydrologic manipulation as a baseline to determine whether maintenance
activities exceed the original scope and effect. Activities exceeding
the original scope and effect will still be allowed when the
manipulation qualifies for an USDA exemption, including the CMWs.
Therefore, a decision to include a particular CMW is based on a
historical analysis by NRCS at the local level on the presence and
degree of hydrological and biogeochemical functions, the impact on
those functions caused by installation of the proposed CMW, and the
subsequent effects on associated floral and faunal communities.
Identification of CMWs
NRCS has 14 years of experience in making minimal effect
determinations in the field, using approved functional assessment
procedures, on a case-by-case basis. To begin the process of developing
CMWs, each NRCS State conservationist reviewed past minimal effect
activities to identify categories of where exemptions were routinely
granted, developed proposed CMWs, and reviewed the proposed CMWs with
the State Technical Committee (STC). The STC includes members of other
Federal agencies, state natural resource agencies, producer
organizations, and other groups, organizations, and private
individuals. Each STC reviewed and made recommendations to their
respective State conservationist about the proposed CMWs. The State
conservationists then decided which CMWs would be proposed and
forwarded them to the NRCS National Office for consideration. Based on
the records of prior minimal effect determinations available to them,
the State Conservationists proposed a total of 16 CMWs.
The NRCS National Office assembled an interdisciplinary team with
representatives from each NRCS region and an U. S. Fish and Wildlife
Service employee to review the 16 proposed CMWs to ensure they met
statutory and regulatory requirements. NRCS requested that the U.S.
Fish and Wildlife Service participate with this team to address the
impacts of the alternatives on the wildlife habitat requirements, as
well as to help satisfy potential impacts to species subject to the
provisions of the Endangered Species Act. This review included all
proposed CMWs as well as identifying any additional conditions
necessary to ensure a CMWs had only minimal effects on wetland
functions and values. In addition, all public comments concerning CMWs
provisions received during the comment period for the Highly Erodible
Lands/Wetland Interim Final Rule published September 6, 1996, were
reviewed. As part of the review, the team used the NRCS Land Resource
Regions and Major Land Resource Areas map to determine the regional
applicability of the proposed CMWs. Each of the CMWs in the proposed
rule has the applicable region identified based on the Land Resource
Area and Major Land Resource Area codes, as well as a reference map.
After review, the team agreed that the following 5 of the proposed 16
CMWs meet the requirements set forth in the 1996 Act. This rule
proposes to amend subpart C of 7 CFR part 12 to include
[[Page 19701]]
the 5 CMWs. USDA finds that the identification of the following CMWs
will improve the implementation of the WC provisions of the 1985 Act,
as amended:
CMW #1--Removal of Woody Vegetation, Including Stumps from Natural
Herbaceous Wetlands
USDA determined that small areas have developed into woody
vegetation on prairie soils, usually through lack of maintenance
practices. These areas exist because natural events such as wildfire
and grazing, which would have resulted in the succession of a non-woody
vegetative community, may no longer occur. The action implicates the
application of the WC provisions because the removal of woody
vegetation makes possible the production of an agricultural commodity
in a wetland area. However, USDA determined that such action, when
conducted under specified conditions identified in the proposed rule,
will not have a significant impact on wildlife and fish habitat, will
enhance the ``prairie wetland'' function by returning these areas to a
more natural seral stage, and will not otherwise implicate the WC
provisions. For sites where cropping is allowed to resume, cropping
history will be verified using official USDA records, or in cases where
records are not available, photographic evidence or other
documentation.
CMW #2--Removal of Scattered Woody Vegetation, Including Stumps
USDA determined that based on past functional assessments, the
removal of scattered woody vegetation, including stumps, from farmed,
hayed, or grazed wetlands will have minimal effect on wetland functions
and values, as long as the criteria for obtaining the exemption from
ineligibility are followed. CMW #2 will apply to the removal of
vegetation and stumps in wetlands that have already been significantly
degraded, and are farmed, hayed, or grazed. This CMW shall only apply
if woody vegetation is scattered within the wetland and comprises less
than 5 percent canopy cover, when measured vertically on the subject
portion of the wetland to be cleared. It shall not apply to any
forested wetlands that were logged within 3 years previous to
conducting the categorical minimal effect determinations, where such
areas comprised trees 20 feet or taller that composed 30 percent or
more of the dominant vegetation. These wetlands typically have reduced
functions and values because of previous manipulation. Because of tree
size, farmers will use other than normal farming operations to remove
the trees and stumps, and the removal will generally be by mechanical
means, such as bulldozers or trackhoes.
However, chemicals could also be used. USDA believes the direct
impact will be the removal of scattered trees and stumps, along with
the possibility of more tillage. Other impacts may include minor
changes to wildlife and fish habitat, possible small changes in
precipitation run-off, and removal of some invasive woody species.
CMW #3--Installation of Grassed Waterways for Erosion Control on non-
Highly Erodible Croplands
USDA determined that this activity is carried out to control
erosion in concentrated flow wetland areas, located in or between non-
highly erodible fields. USDA determined that the direct impacts include
short-term construction disturbance, decrease in erosion and sediment
delivery, improvement in run-off water quality, and possibly some loss
of degraded wetlands. USDA believes that the impacts to wildlife and
fish habitat should be positive, since eroding areas will be
permanently revegetated to native or other approved species. Based on
past functional assessments, USDA determined that the installation of
grassed waterways in these wetlands will have minimal effect on wetland
functions and values, as long as all conditions as set forth in the
proposed rule are met.
CMW #4--Terrace Construction for Erosion Control on Erodible Cropland
Since this activity may result in the manipulation of wetlands, a
person could violate the wetland conservation provisions. Typically,
these wetlands have already been altered in the past. USDA determined
that the direct impacts include control of erosion, reduction of
sediment moving off-site, and improvement of water quality. Other
impacts may include partial diversion of runoff waters from wetlands
located down slope from the activity. USDA has consistently found that
impacts to wildlife and fisheries habitat will be minimal, since most
of these areas are already in cropland. However, the activity may
result in placement of fill within wetlands. Based on past functional
assessments, USDA determined that the installation of terraces through
these wetlands will have minimal effect on wetland functions and
values, as long as all conditions set forth in the proposed rule are
met.
CMW #5--Control or Removal of Exotic Invasive Woody Species, Including
Stumps
USDA determined that the species listed under this CMW are either
invasive or exotic, and generally have a negative environmental impact
on wetland ecology. Most of these species colonize wetlands after some
earlier disturbance has taken place. In many areas, the species invade
the wetland and riparian zones, some of the most important and limited
wildlife habitat. These species do not replace the habitat value of
native vegetative species. In addition, the exotic species have minimal
value for erosion control and bank stabilization, and may contribute to
water quality and quantity problems.
The CMW provides that no additional alterations to the hydric
conditions are allowed. USDA determined that these wetlands would
function at an equal or higher level after the removal of the exotic
invasive species, and when the wetland is being managed according to
the criteria in the proposed rule. In addition, USDA believes indirect
impacts from removal of these exotic species are positive because of
protection from invasion to adjacent natural areas. Impacts to wildlife
and fish habitat should be positive, since invasive, noxious vegetative
species will be removed.
Some of these wetlands have been previously converted back to
cropland or pastureland, with the approval of the Corps of Engineers,
Fish and Wildlife Service, and NRCS. Based on assessment of these
conversions, USDA determined that the removal of the species listed
would have minimal effect on wetland functions and values, as long as
all criteria are followed.
Mandatory Conditions of Exemption Eligibility
The proposed CMW exemptions are required by statute to provide
farmers, ranchers and other landowners with needed flexibility to
perform routine land maintenance on cropland and pastureland in a
manner that will result in only minimal impacts to wetland functions.
During the development of each CMW, specific conditional requirements
were incorporated, which must be rigidly adhered to for an exemption to
apply. These conditions will result in the safeguarding of threatened
and endangered species habitat, protection of adjacent wetlands,
streams and water bodies, enhancement of bio-diversity for native
wetland flora, and assure exemption-related activities are implemented
according to science-based standards and specifications. Of
[[Page 19702]]
the five proposed CMWs, No.'s 1, 2, 3 and 4 may only be used where
farmed wetlands and farmed wetland pastures occur. These landuse
wetlands have been previously and significantly degraded through normal
agricultural activities such as annual tillage, haying or grazing.
Additionally, many of the activities associated with the application of
CMWs will result in direct benefits to wetlands, fish and wildlife
habitat, and water quality. For example, CMW # 5 will allow the removal
of exotic, invasive woody plants that have invaded wetlands and
riparian zones. CMWs No.'s 3 and 4 will result in improved water
quality by reducing erosion and sediment delivery to downstream
wetlands, streams and tributaries.
Since each CMW was developed by incorporating numerous, mandatory
restrictive conditions that should result in only limited impacts to
wetland ecosystems, NRCS believes there is no need for the application
of additional acreage limitations such as the one-half acre limitation
used by the Corps for implementing nationwide permits under section 404
of the Clean Water Act. However, in order to enhance programmatic
consistency between all other Federal, state and local wetland
protection laws and the 1985 Act, NRCS is specifically soliciting
comments from the public regarding possible acreage limitations for any
or all of the CMWs.
Continued Coordination With Other Federal Agencies
Consistent with the intent expressed in the preamble to the current
interim final rule (Federal Register Volume #61, Number 174), the
changes proposed in this rule ``do not supersede the wetland protection
authorities and responsibilities of the Environmental Protection Agency
(EPA) or the Corps of Engineers (COE) under section 404 of the Clean
Water Act.'' This proposed rule is promulgated under the authority of
the 1985 Act, as amended, and therefore, does not affect the
obligations of any person under other Federal statutes, or the legal
authorities of any other Federal agency including, for example, EPA's
authority to determine the geographic scope of Clean Water Act
jurisdiction. Nonetheless, NRCS, the COE and EPA place a high priority
on adopting procedures and policies that minimize duplication and
inconsistencies between the wetland conservation provisions of the 1985
Act and the Clean Water Act section 404 programs. Any one who wishes to
utilize the CMWs described in this proposed rule is advised to contact
the local COE and State officials to ensure that activities meet any
compliance requirements. Further, anyone wishing to come within the
coverage of any of the CMWs must ensure that actions comply with all of
the conditions set forth for the particular CMW.

farmed wetland pastures, where such wetlands are identified as
depressions, lacustrine fringe, riverine, or slope wetlands under the
hydrogeomorphic classification system.
(E) Conditions necessary to obtain exemption from ineligibility.
The removal of the woody vegetation from the natural herbaceous
wetlands must:
(1) Disturb only the soil necessary to complete the activity;
(2) Result in woody materials not being placed in waters of the
United States;
(3) Not encompass greater than \1/2\ acre of manipulation of woody
vegetation per Farm Tract.
(4) Be on soils that formed under mid and tall grass prairie
conditions;
(5) Not be cropped unless the majority of the manipulated portion
of the wetland has a cropping history; and
(6) Not be applied within occupied Federally protected threatened
and endangered species habitat, or within Federally designated critical
habitat.
(iv) CMW #2--Removal of scattered woody vegetation, including
stumps:
(A) Purpose. CMW # 2 allows clearing of scattered woody vegetation
in wetland areas that have previously been manipulated and are
currently cropped, hayed, or grazed.
(B) 1996 Act trigger. The removal of scattered woody vegetation and
stumps from a wetland through means other than normal tillage
operations.
(C) Scope. CMW #2 shall only be applicable to the following land
resource regions and MLRAs: A, B, C, I, J, K, L, M, N, O, P, R, S, T,
and U. See Map #2.

[GRAPHIC] [TIFF OMITTED] TP23AP02.010
(D) Wetland types. CMW #2 may only be used on farmed wetlands and
farmed wetland pastures, where such wetlands are identified as
depressions, lacustrine fringe, mineral soil flats, organic soil flats,
riverine, or slope wetlands under the hydrogeomorphic classification
system.
(E) Conditions necessary to obtain exemption from ineligibility.
The removal of scattered woody vegetation, including stumps must:
(1) Result in the stems and stumps not being placed in a waters of
the United States;
(2) Be on wetland areas currently cropped, grazed or hayed;
(3) Disturb only the minimum area and soil necessary to complete
the stem and stump removal;
(4) Be on areas where the woody vegetation is scattered, not
clustered, and where woody vegetation comprises less than 5 percent
canopy cover within the wetland, when measured vertically.

otherwise convert depressional wetlands that occur along the waterway;
and
(8) Not be applied within occupied Federally protected threatened
and endangered species habitat, or within Federally designated critical
habitat.
(F) Additional criteria.
(1) CMW #3 does not apply to wooded areas.
(2) The constructed waterway cannot reduce the size of the pre-
construction permanently vegetated area by more than 10 percent.
(3) The waterway, once constructed, must be revegetated to an
approved native or introduced seed mixture suitable for the site and
accommodating wildlife needs whenever possible.
(4) The operation and management of the grassed waterway, including
mowing or grazing of the waterway, must be in accordance with the NRCS
standards and restrictions for grassed waterways as found in the FOTG,
which may be obtained at any local NRCS office.
(vi) CMW #4--Terrace construction for erosion control on erodible
cropland:
(A) Purpose. CMW #4 allows terrace construction for erosion control
on erodible cropland.
(B) 1996 Act trigger. This may be completed for the purpose of, or
to make possible, the production of an
[[Page 19706]]
agricultural commodity by either manipulating a wetland in the field or
by altering the hydrology of adjacent or downslope wetlands.
(C) Scope. CMW #4 shall be available only in the following land
resource regions and MLRA(s): F, G, H, L, M, R, and S. See Map #4.
[GRAPHIC] [TIFF OMITTED] TP23AP02.012

farmed wetland pastures, where such wetlands are identified as sloped
wetlands under the hydrogeomorphic classification system.
(E) Conditions necessary to obtain exemption from ineligibility.
The terrace construction must:
(1) Be carried out only for the purpose of erosion control in
fields where the erosion rate is greater than the tolerable ``T'' soil
erosion rate, as identified in the NRCS Field Office Technical Guide;
(2) Be built with a non-erosive outlet, and according to practice
standards in the NRCS Field Office Technical Guide, which may be
obtained at any local NRCS office;
(3) Be drained with non-perforated tile if underground outlets for
terraces are installed;
(4) Be designed to minimize adverse impacts to adjacent or
downslope (not in the terraced field) wetlands;
(5) Precipitation run-off normally entering a down slope wetland
should be maintained such that the wetland hydrological conditions are
similar to pre-construction conditions;
(6) Be completed no closer to any off-site wetland, than the
distance of one terrace spacing, according to NRCS Field Office
Technical Guide; and
(7) Not be applied within occupied Federally protected threatened
and endangered species habitat, or within Federally designated critical
habitat.
(vii) CMW #5--Control or removal of exotic and/or invasive woody
species, including stumps:
(A) Purpose. CMW #5 allows the removal of the following species:
Australian pine (Casuarina equisetifolia), Brazilian pepper (Schinus
