(a) Ineligible land
The Secretary may not use program funds for the purposes of acquiring an easement on—

(1) lands owned by an agency of the United States, other than land held in trust for Indian tribes;

(2) lands owned in fee title by a State, including an agency or a subdivision of a State, or a unit of local government;

(3) land subject to an easement or deed restriction which, as determined by the Secretary, provides similar protection as would be provided by enrollment in the program; or

(4) lands where the purposes of the program would be undermined due to on-site or off-site conditions, such as risk of hazardous substances, permitted or existing rights of way, infrastructure development, or adjacent land uses.

(b) Priority
In evaluating applications under the program, the Secretary may give priority to land that is currently enrolled in the conservation reserve program in a contract that is set to expire within 1 year and—

(1) in the case of an agricultural land easement, is grassland that would benefit from protection under a long-term easement; and

(2) in the case of a wetland reserve easement, is a wetland or related area with the highest wetland functions and value and is likely to return to production after the land leaves the conservation reserve program.

(c) Subordination, exchange, modification, and termination

(1) Subordination
The Secretary may subordinate any interest in land, or portion of such interest, administered by the Secretary (including for the purposes of utilities and energy transmission services) either directly or on behalf of the Commodity Credit Corporation under the program if the Secretary determines that the subordination—

(A) increases conservation values or has a limited negative effect on conservation values;

(B) minimally affects the acreage subject to the interest in land; and

(C) is in the public interest or furthers the practical administration of the program.

(2) Modification and exchange

(A) Authority
The Secretary may approve a modification or exchange of any interest in land, or portion of such interest, administered by the Secretary, either directly or on behalf of the Commodity Credit Corporation under the program if the Secretary determines that—

(i) no reasonable alternative exists and the effect on the interest in land is avoided or minimized to the extent practicable; and

(ii) the modification or exchange—

(I) results in equal or increased conservation values;

(II) results in equal or greater economic value to the United States;

(III) is consistent with the original intent of the easement;

(IV) is consistent with the purposes of the program; and

(V) is in the public interest or furthers the practical administration of the program.

(B) Limitation
In modifying or exchanging an interest in land, or portion of such interest, under this paragraph, the Secretary may not increase any payment to an eligible entity.

(3) Termination
The Secretary may approve a termination of any interest in land, or portion of such interest, administered by the Secretary, directly or on behalf of the Commodity Credit Corporation under the program if the Secretary determines that—

(A) termination is in the interest of the Federal Government;

(B) the United States will be fully compensated for—

(i) the fair market value of the interest in land;

(ii) any costs relating to the termination; and

(iii) any damages determined appropriate by the Secretary; and

(C) the termination will—

(i) address a compelling public need for which there is no practicable alternative even with avoidance and minimization; and

(ii) further the practical administration of the program.

(4) Consent
The Secretary shall obtain consent from the landowner and eligible entity, if applicable, for any subordination, exchange, modification, or termination of interest in land, or portion of such interest, under this subsection.

(5) Notice
At least 90 days before taking any termination action described in paragraph (3), the Secretary shall provide written notice of such action to the Committee on Agriculture of the House of Representatives and the Committee on Agriculture, Nutrition, and Forestry of the Senate.
