Title 43 › CHAPTER 12 — RECLAMATION AND IRRIGATION OF LANDS BY FEDERAL GOVERNMENT › SUBCHAPTER I — GENERAL PROVISIONS › § 390b–2
The Secretary may, when a non-Federal group asks, look at plans to get more water from a federal water project by changing the project, changing how it is run, or using water the project releases. Plans can include things like adding storage, diverting released or withdrawn water to recharge groundwater or store in aquifers or other facilities, building delivery or access facilities, or any mix of these. The rule does not apply to plans that take water from existing supplies or cut water for an authorized project use. If the project is run by a different federal agency, the Secretary can only act on parts that the Secretary has authority over. When a plan is sent in, the Secretary must share it and follow public participation rules. That includes consulting affected States, power marketing administrations for hydropower reservoirs, entities that pay operation or maintenance, people with contracts to use the water or storage, those a State says have water rights, and local governments downstream with flood duties. The Secretary can use the project’s own authorization or other laws (for example, section 549a of title 33, section 390b, or section 408 of title 33) to review or approve plans. The Secretary must not approve plans that the project’s operating agency (if not the Army) does not support, that hurt the project’s authorized purposes, that harm contractual or State water rights, that raise costs for others, or that conflict with section 390b(e) unless Congress approves. Non-Federal interests must pay all costs to develop, review, and carry out a plan, except that entities eligible under section 1962d–16 of title 42 may get 50 percent help for the review. Non-Federal sponsors must also pay separable operation and maintenance costs, and for some new storage they must pay a share of joint-use costs under section 390b. The Secretary may accept contributed funds to do reviews or to prepare or change operational documents for certain reservoirs (those covered by section 709 of title 33). The Secretary can give technical help if the requester pays all costs. The rule does not apply to reservoirs in the Upper Missouri River, the Apalachicola‑Chattahoochee‑Flint system, the Alabama‑Coosa‑Tallapoosa system, or the Stones River, and it does not change the Secretary’s other reservoir authorities.
