The Secretary is authorized to review water resources projects constructed by the Secretary to determine the need for modifications in the structures and operations of such projects for the purpose of improving the quality of the environment in the public interest and to determine if the operation of such projects has contributed to the degradation of the quality of the environment.
The Secretary is authorized to carry out a program for the purpose of making such modifications in the structures and operations of water resources projects constructed by the Secretary which the Secretary determines (1) are feasible and consistent with the authorized project purposes, and (2) will improve the quality of the environment in the public interest.
If the Secretary determines that construction of a water resources project by the Secretary or operation of a water resources project constructed by the Secretary has contributed to the degradation of the quality of the environment, the Secretary may undertake measures for restoration of environmental quality and measures for enhancement of environmental quality that are associated with the restoration, through modifications either at the project site or at other locations that have been affected by the construction or operation of the project, if such measures do not conflict with the authorized project purposes.
The non-Federal share of the cost of any modifications or measures carried out or undertaken pursuant to subsection (b) or (c) shall be 25 percent. The non-Federal share may be provided in kind, including a facility, supply, or service that is necessary to carry out the modification or measure. Not more than $10,000,000 in Federal funds may be expended on any single modification or measure carried out or undertaken pursuant to this section.
The Secretary shall coordinate any actions taken pursuant to this section with appropriate Federal, State, and local agencies.
Notwithstanding section 1962d–5b of title 42, a non-Federal sponsor for any project carried out under this section may include a nonprofit entity, with the consent of the affected local government.
There is authorized to be appropriated not to exceed $50,000,000 annually to carry out this section.
In this section, the term “water resources project constructed by the Secretary” includes a water resources project constructed or funded jointly by the Secretary and the head of any other Federal agency (including the Natural Resources Conservation Service).
