Title 43 › CHAPTER 12 — RECLAMATION AND IRRIGATION OF LANDS BY FEDERAL GOVERNMENT › SUBCHAPTER XI–B — AGING INFRASTRUCTURE › § 510b
The Secretary may do urgent or unusual operation and maintenance work on a project facility when it is needed to keep the facility safe. If the work is on a reserved project, the costs are charged to the project and must be paid back with interest within 50 years starting the year the work is mostly done. If the work is on a transferred project, the Secretary can pay the costs up front and make a 50-year repayment contract with the project’s beneficiaries. Those repayment contracts are not treated as new or changed contracts under section 390cc(a). The interest rate is set by the Secretary of the Treasury at the start of the fiscal year when the work begins. The rate is based on average market yields for U.S. government bonds with similar maturities and is rounded to the nearest eighth of a percent on any unpaid balance. If immediate danger exists, the Secretary or the transferred works operator must do emergency work to prevent harm to people or property. The Secretary may advance money for emergency work and will ask to be repaid after getting a written promise to negotiate a repayment contract. For certain inspected facilities, the Secretary may cover 35 percent of the transferred operator’s share of emergency costs with nonreimbursable Federal funds; the rest must be repaid under the rules above. The Aging Infrastructure Account is set up in the Treasury to pay for eligible major, non-recurring maintenance projects and to allow extended repayment. It gets money from specific appropriations under section 510d and from repayments. Starting in fiscal year 2022 the Secretary will accept yearly applications, using guidelines issued within 60 days after December 27, 2020, and will report chosen projects and account details to Congress within 90 days after each application period ends. Congress can direct different allocations, and earlier contracts or funding before December 27, 2020 are not affected.
