§510b Extraordinary Operation and Maintenance Work Performed by the Secretary

Summary

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.

(1)Treatment of costs
For reserved works, costs incurred by the Secretary in conducting extraordinary operation and maintenance work will be allocated to the authorized reimbursable purposes of the project and shall be repaid within 50 years, with interest, from the year in which work undertaken pursuant to this subchapter is substantially complete.

For transferred works, the Secretary is authorized to advance the costs incurred by the transferred works operating entity in conducting extraordinary operation and maintenance work and negotiate appropriate 50-year repayment contracts with project beneficiaries providing for the return of reimbursable costs, with interest, under this subsection: Provided, however, That no contract entered into pursuant to this subchapter shall be deemed to be a new or amended contract for the purposes of section 390cc(a) of this title.
(3)Determination of interest rate
The interest rate used for computing interest on work in progress and interest on the unpaid balance of the reimbursable costs of extraordinary operation and maintenance work authorized by this subchapter shall be determined by the Secretary of the Treasury, as of the beginning of the fiscal year in which extraordinary operation and maintenance work is commenced, on the basis of average market yields on outstanding marketable obligations of the United States with the remaining periods of maturity comparable to the applicable reimbursement period of the project, adjusted to the nearest ⅛ of 1 percent on the unamortized balance of any portion of the loan.
