Last updated Sep 23, 2026|Official source

Summary

The Secretary must find, map, and officially say which areas on farm land are wetlands. The Secretary must make wetland maps and try to do a ground visit if someone asks. People get notice before a map is certified for deciding if they lose program benefits. They can appeal before the decision is final. A final certification stays in force while the land is farmed or until the owner asks for a new review. If someone appeals, the Secretary will check the map and visit the land. If a person acted based on an earlier certified map, they won’t be hurt by a later change unless they ask for a new certification. The Secretary must visit the land before withholding program payments, usually with the person there, unless a reasonable effort was made to include them. The Secretary will set regional rules for small “minimal effect” actions and train staff to apply them. Nonwetlands are lands that do not have mostly hydric soils, are not flooded or saturated enough to support water-loving plants, or do not normally support such plants. People do not lose program payments in many specific situations, for example for certain converted wetlands before December 23, 1985, for nontidal ditches dug in upland, for wet spots made by irrigation or water systems, for artificial ponds used for livestock or rice or similar uses, or for temporary wetlands from nearby development. Conversions that reverted to wetland because of lack of maintenance or events beyond the farmer’s control are also covered. Actions that have only a minimal effect, or that are offset by restoring, enhancing, or creating wetland nearby under an approved plan paid for by the person, can keep eligibility. Restoration or enhancement is normally done at a one-for-one acreage basis unless more is needed; created wetlands may need more than one-for-one. Conversions after December 23, 1985 but before November 28, 1990 can be treated similarly if mitigated. A Clean Water Act permit that included adequate mitigation also counts. People can appeal if they are required to mitigate at greater than one-to-one. The Secretary may excuse someone who acted in good faith and did not mean to break the rules, and will give up to 1 year to begin restoring the wetland. The Natural Resources Conservation Service makes technical decisions and plans. The Secretary must run or support mitigation banks to help people meet these rules and can make policy so people can use existing banks without the Secretary having to hold an easement. Up to $5,000,000 is authorized for each fiscal year 2019 through 2023 to help with this.

(a)Delineation by Secretary
(1)In general
Subject to subsection (b) and paragraph (6), the Secretary shall delineate, determine, and certify all wetlands located on subject land on a farm.
(2)Wetland delineation maps
The Secretary shall delineate wetlands on wetland delineation maps. On the request of a person, the Secretary shall make a reasonable effort to make an on-site wetland determination prior to delineation.
(3)Certification
On providing notice to affected persons, the Secretary shall—
(A)certify whether a map is sufficient for the purpose of making a determination of ineligibility for program benefits under section 3821 of this title; and
(B)provide an opportunity to appeal the certification prior to the certification becoming final.
(4)Duration of certification
A final certification made under paragraph (3) shall remain valid and in effect as long as the area is devoted to an agricultural use or until such time as the person affected by the certification requests review of the certification by the Secretary.
(5)Review of mapping on appeal
In the case of an appeal of the Secretary’s certification, the Secretary shall review and certify the accuracy of the mapping of all land subject to the appeal to ensure that the subject land has been accurately delineated. Prior to rendering a decision on the appeal, the Secretary shall conduct an on-site inspection of the subject land on a farm.
(6)Reliance on prior certified delineation
No person shall be adversely affected because of having taken an action based on a previous certified wetland delineation by the Secretary. The delineation shall not be subject to a subsequent wetland certification or delineation by the Secretary, unless requested by the person under paragraph (4).
(b)Exemptions
No person shall become ineligible under section 3821 of this title for program loans or payments under the following circumstances:
(1)As the result of the production of an agricultural commodity on the following lands:
(A)A converted wetland if the conversion of the wetland was commenced before December 23, 1985.
(B)Land that is a nontidal drainage or irrigation ditch excavated in upland.
(C)A wet area created by a water delivery system, irrigation, irrigation system, or application of water for irrigation.
(D)A wetland on which the owner or operator of a farm or ranch uses normal cropping or ranching practices to produce an agricultural commodity in a manner that is consistent for the area where the production is possible as a result of a natural condition, such as drought, and is without action by the producer that destroys a natural wetland characteristic.
(E)Land that is an artificial lake or pond created by excavating or diking land (that is not a wetland) to collect and retain water and that is used primarily for livestock watering, fish production, irrigation, wildlife, fire control, flood control, cranberry growing, or rice production, or as a settling pond.
(F)A wetland that is temporarily or incidentally created as a result of adjacent development activity.
(G)A converted wetland if the original conversion of the wetland was commenced before December 23, 1985, and the Secretary determines the wetland characteristics returned after that date as a result of—
(i)the lack of maintenance of drainage, dikes, levees, or similar structures;
(ii)a lack of management of the lands containing the wetland; or
(iii)circumstances beyond the control of the person.
(H)A converted wetland, if—
(i)the converted wetland was determined by the Natural Resources Conservation Service to have been manipulated for the production of an agricultural commodity or forage prior to December 23, 1985, and was returned to wetland conditions through a voluntary restoration, enhancement, or creation action subsequent to that determination;
(ii)technical determinations regarding the prior site conditions and the restoration, enhancement, or creation action have been adequately documented by the Natural Resources Conservation Service;
(iii)the proposed conversion action is approved by the Natural Resources Conservation Service prior to implementation; and
(iv)the extent of the proposed conversion is limited so that the conditions will be at least equivalent to the wetland functions and values that existed prior to implementation of the voluntary wetland restoration, enhancement, or creation action.
(2)For the conversion of the following:
(A)An artificial lake or pond created by excavating or diking land that is not a wetland to collect and retain water and that is used primarily for livestock watering, fish production, irrigation, wildlife, fire control, flood control, cranberry growing, rice production, or as a settling pond.
(B)A wetland that is temporarily or incidentally created as a result of adjacent development activity.
(C)A wetland on which the owner or operator of a farm or ranch uses normal cropping or ranching practices to produce an agricultural commodity in a manner that is consistent for the area where the production is possible as a result of a natural condition, such as drought, and is without action by the producer that destroys a natural wetland characteristic.
(D)A wetland previously identified as a converted wetland (if the original conversion of the wetland was commenced before December 23, 1985), but that the Secretary determines returned to wetland status after that date as a result of—
(i)the lack of maintenance of drainage, dikes, levees, or similar structures;
(ii)a lack of management of the lands containing the wetland; or
(iii)circumstances beyond the control of the person.
(E)A wetland, if—
(i)the wetland was determined by the Natural Resources Conservation Service to have been manipulated for the production of an agricultural commodity or forage prior to December 23, 1985, and was returned to wetland conditions through a voluntary restoration, enhancement, or creation action subsequent to that determination;
(ii)technical determinations regarding the prior site conditions and the restoration, enhancement, or creation action have been adequately documented by the Natural Resources Conservation Service;
(iii)the proposed conversion action is approved by the Natural Resources Conservation Service prior to implementation; and
(iv)the extent of the proposed conversion is limited so that the conditions will be at least equivalent to the wetland functions and values that existed prior to implementation of the voluntary wetland restoration, enhancement, or creation action.
(c)On-site inspection requirement
(1)In general
No program loans, payments, or benefits shall be withheld from a person under this subchapter unless the Secretary has conducted an on-site visit of the subject land, which, except as provided in paragraph (2), shall be conducted in the presence of the affected person.
(2)Exception
The Secretary may conduct an on-site visit under paragraph (1) without the affected person present if the Secretary has made a reasonable effort to include the presence of the affected person at the on-site visit.
(d)Identification of minimal effect exemptions
For purposes of applying the minimal effect exemption under subsection (f)(1), the Secretary shall identify by regulation categorical minimal effect exemptions on a regional basis to assist persons in avoiding a violation of the ineligibility provisions of section 3821 of this title. The Secretary shall ensure that employees of the Department of Agriculture who administer this subchapter receive appropriate training to properly apply the minimal effect exemptions determined by the Secretary.
(e)Nonwetlands
The Secretary shall exempt from the ineligibility provisions of section 3821 of this title any action by a person upon lands in any case in which the Secretary determines that any one of the following does not apply with respect to such lands:
(1)Such lands have a predominance of hydric soils.
(2)Such lands are inundated or saturated by surface or groundwater at a frequency and duration sufficient to support a prevalence of hydrophytic vegetation typically adapted for life in saturated soil conditions.
(3)Such lands, under normal circumstances, support a prevalence of such vegetation.
(f)Minimal effect; mitigation
The Secretary shall exempt a person from the ineligibility provisions of section 3821 of this title for any action associated with the production of an agricultural commodity on a converted wetland, or the conversion of a wetland, if 1 or more of the following conditions apply, as determined by the Secretary:
(1)The action, individually and in connection with all other similar actions authorized by the Secretary in the area, will have a minimal effect on the functional hydrological and biological value of the wetlands in the area, including the value to waterfowl and wildlife.
(2)The wetland and the wetland values, acreage, and functions are mitigated by the person through the restoration of a converted wetland, the enhancement of an existing wetland, or the creation of a new wetland, and the restoration, enhancement, or creation is—
(A)in accordance with a wetland conservation plan;
(B)in advance of, or concurrent with, the action;
(C)not at the expense of the Federal Government;
(D)in the case of enhancement or restoration of wetlands, on not greater than a 1-for-1 acreage basis unless more acreage is needed to provide equivalent functions and values that will be lost as a result of the wetland conversion to be mitigated;
(E)in the case of creation of wetlands, on greater than a 1-for-1 acreage basis if more acreage is needed to provide equivalent functions and values that will be lost as a result of the wetland conversion that is mitigated;
(F)on lands in the same general area of the local watershed as the converted wetland; and
(G)with respect to the restored, enhanced, or created wetland, made subject to an easement that—
(i)is recorded on public land records;
(ii)remains in force for as long as the converted wetland for which the restoration, enhancement, or creation to be mitigated remains in agricultural use or is not returned to its original wetland classification with equivalent functions and values; and
(iii)prohibits making alterations to the restored, enhanced, or created wetland that lower the wetland’s functions and values.
(3)The wetland was converted after December 23, 1985, but before November 28, 1990, and the wetland values, acreage, and functions are mitigated by the producer through the requirements of subparagraphs (A), (B), (C), (D), (F), and (G) of paragraph (2).
