§604 Lines of Credit

Title 23 › CHAPTER 6 — INFRASTRUCTURE FINANCE › § 604

Last updated Sep 22, 2026|Official source

Summary

The Secretary can agree to provide a line of credit—meaning money set aside as a future direct loan—for projects chosen for the program. That money can only be used to pay project debt, big repairs or replacements, operation and maintenance, and costs from unexpected federal or state environmental rules. Before making an agreement, the Secretary must work with the Office of Management and Budget and rating agencies to set a capital reserve subsidy amount. The project’s senior obligations must get an investment‑grade rating from two rating agencies before the line is funded. Each line of credit is set up with terms the Secretary finds appropriate. The line cannot be larger than 33 percent of the project’s expected eligible costs. Any draw becomes a direct loan and can be used only if the project’s net revenues (including capitalized interest but not financing reserves) can’t cover the needed costs. The interest rate must be at least the yield on 30‑year U.S. Treasury securities on the agreement date, unless specific exceptions apply. The loan is to be paid from tolls, user fees, public‑private partnership payments, or other dedicated revenues that also back the main project debts, and it must include a rate or coverage promise to support payments. The full undrawn amount is available for 10 years after the project’s substantial completion. Credit draws do not give third parties any claim against the Federal Government. The borrower may assign the line to lenders or a trustee. Generally, the federal loan won’t be put behind other creditors in bankruptcy, but the Secretary can waive that rule for certain public agencies if strict conditions are met; if waived, federal subsidy is limited to 10 percent of the loan principal and the borrower must pay the rest. The Secretary may charge fees to cover costs. A project cannot get a secured loan or guarantee that, together with this line, exceeds 49 percent of eligible costs. Repayment terms are based on projected cash flow and the asset’s useful life, must start no later than 5 years after the 10‑year availability period ends, and must be fully repaid by 25 years after that period ends.
