The bill amends 23 U.S.C. to expand what counts as an airport-related project eligible for TIFIA assistance. It adds 'equipment' and expressly permits projects that are revenue-producing or not publicly accessible (for example, rental car or parking facilities that serve airports), and it adjusts program rules and waiver conditions that previously applied to TIFIA eligibility decisions for airport projects.
Separately, it raises the threshold for a streamlined 'small' TIFIA loan from $75 million in expected eligible project costs to a $100 million TIFIA loan amount.
For professionals in airport finance, municipal credit, and transportation program administration, the change reallocates who can access federal credit and how DOT will evaluate airport projects. The net effect is to make a wider universe of airport-related investments—including privately operated or revenue-generating facilities—more likely to receive TIFIA support, while shifting underwriting focus and increasing potential federal credit exposure for these types of projects.
At a Glance
What It Does
The bill revises 23 U.S.C. §601(a)(12)(G) to make new or improved aviation facilities—including equipment and facilities that are revenue-producing or not open to the public—eligible for TIFIA. It amends selection and waiver language in sections 602 and 603 and increases the program’s small-loan threshold in §605(f)(1) from $75 million (in anticipated eligible project costs) to a $100 million TIFIA loan amount.
Who It Affects
Major and regional airports, airport concession operators (rental car, parking, ground handling), private developers and P3 investors structuring airport projects, bond counsels and underwriters, and DOT’s TIFIA program office responsible for underwriting and oversight.
Why It Matters
By explicitly allowing revenue-generating and non-public airport facilities into TIFIA, the bill opens federal credit to assets previously ambiguous or excluded. That changes underwriting metrics, expands the set of projects competing for federal credit, and shifts some programmatic risk toward the federal government and ultimately taxpayers.

What This Bill Actually Does
The bill changes which airport-related activities count as eligible TIFIA projects. The revised statutory language in 23 U.S.C. §601(a)(12)(G) adds 'equipment' to the list and removes limiting language tied to public accessibility and revenue-generation.
Concretely, the amendment lists projects that construct or improve aviation facilities that facilitate air transportation, access to air transportation (explicitly naming surface access, rental car, and parking), passenger/baggage/cargo movement, or the safety and security of airport users—without requiring those facilities to be publicly accessible or non-revenue generating.
On how projects are selected, the bill carves airport projects defined in the amended §601(a)(12)(G) out of certain language in §602(a). One change also shifts a phrase in the program’s evaluation criteria from 'eligible project costs' to 'a Federal credit instrument,' which signals that DOT should focus on the federal credit product being provided (for example, the loan or loan guarantee) rather than solely on total project costs when assessing certain aspects of eligibility or selection.The bill also narrows the statutory conditions that must be met for a waiver under §603(b)(6).
It adds a provision explicitly stating that two waiver conditions (identified in the statute as subparagraphs (B)(i)(III) and (6)(B)(ii)(I)) are not required for projects falling under the airport-specific eligibility expansion. That lowers regulatory hurdles for airport projects seeking a statutory waiver of normal requirements.Finally, the legislation alters program administration under §605(f)(1) by replacing the current reference to projects with anticipated eligible project costs of $75 million or less with a test tied to the TIFIA loan amount, raising the effective small-project threshold to TIFIA loans reasonably anticipated not to exceed $100 million.
Practically, that expands the set of airport projects that can access streamlined or simplified TIFIA processing tied to the smaller-loan category.
The Five Things You Need to Know
The bill rewrites 23 U.S.C. §601(a)(12)(G) to include 'equipment' and to allow airport-related projects 'regardless of revenue producing purposes or public accessibility.', Section 602(a) is amended so that the phrase beginning 'A project' does not apply to projects described in the revised §601(a)(12)(G), effectively carving those airport projects out of that particular eligibility determination clause.
Section 602(a)(5)(B)(iii) replaces the term 'eligible project costs' with 'a Federal credit instrument,' shifting an evaluative focus from total project costs to the federal credit product.
Section 603(b)(6) adds an explicit rule that two specific waiver conditions in the statute (subparagraphs (B)(i)(III) and (6)(B)(ii)(I)) are not required for the newly defined airport projects to receive a waiver.
Section 605(f)(1) changes the small-project test from projects with anticipated eligible costs under $75 million to projects with a TIFIA loan amount reasonably anticipated not to exceed $100 million.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
Short title
Names the measure the 'Airport TIFIA Financing Certainty Act.' This is a conventional headnote but signals the bill’s narrow scope: the amendments are limited to TIFIA rules relating to airport projects and related program administration.
Expands what qualifies as an airport-related eligible project
This provision broadens the statutory definition to include construction or improvement of aviation-related facilities and 'equipment' and explicitly allows eligibility 'regardless of revenue producing purposes or public accessibility.' Listing surface transportation, rental car, and parking facilities clarifies that ancillary airport infrastructure commonly funded by user fees or privately operated can qualify for TIFIA. Practically, projects that previously raised doubts—private parking garages, consolidated rental-car centers, cargo handling equipment—now have a clear path to apply for federal credit under TIFIA.
Carve-out from one eligibility determination clause and change in evaluative language
The amendment to paragraph (3) removes the application of an existing 'A project...' clause to airport projects described in the new §601(a)(12)(G), narrowing the set of statutory determinations that automatically apply. The edit in paragraph (5)(B)(iii) swaps 'eligible project costs' for 'a Federal credit instrument,' which will require DOT to treat the nature and structure of the federal credit (loan, guarantee, line of credit) as the unit of analysis in certain selection or assessment steps instead of relying solely on aggregate cost thresholds.
Waiver conditions made inapplicable to the new airport projects
This change adds subparagraph (C) to make two listed waiver conditions inapplicable to projects under §601(a)(12)(G). In operational terms, airport projects can obtain statutory waivers without satisfying those specific conditions, which reduces regulatory friction for projects that otherwise might have failed to meet rigid statutory waiver prerequisites.
Raises the 'small' TIFIA loan threshold to a $100M loan amount
By replacing a $75 million anticipated eligible-project-cost ceiling with a $100 million TIFIA loan amount ceiling, the bill increases the ceiling for projects eligible for whatever administrative or procedural treatment the statute ties to that subsection. The change anchors the test to the federal credit product size (the loan amount) rather than to projected total project costs, which can materially affect eligibility for streamlined handling.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- Airport authorities and operators — The expanded definition lets them seek TIFIA support for a wider range of capital works (equipment, rental car centers, parking, cargo handling) including projects that generate revenue or are not publicly accessible.
- Private developers and P3 sponsors of airport facilities — The explicit eligibility for revenue-producing assets reduces a legal barrier to using TIFIA alongside private capital, improving deal finance flexibility.
- Concession operators (rental car and parking companies) — These firms can participate in or back projects that now qualify for federal credit, potentially lowering financing costs for facility improvements that directly serve their operations.
- Regional economic development stakeholders — More airport-capacity and access projects may secure low-cost federal credit, accelerating projects that affect freight, passenger throughput, and surface access.
Who Bears the Cost
- U.S. Department of Transportation/TIFIA program administrators — They will face additional underwriting workload and potentially more complex risk assessments as a broader array of revenue-based and equipment financings seek federal credit.
- Federal taxpayers — Expanding eligibility to revenue-generating and non-public assets increases the program’s potential credit exposure and subsidy cost, which ultimately rests on the federal budget.
- Municipal borrowers and other transportation projects — Increased competition for limited TIFIA capacity could push down the share of federal credit available to non-airport projects or require DOT to prioritize among more applicants.
- Bondholders in existing airport financings — If TIFIA is used to back facilities that were previously financed through private or municipal bonds, market dynamics and relative credit positions could shift, affecting pricing and covenant structures.
Key Issues
The Core Tension
The central tension is between expanding access to low-cost federal credit to accelerate airport modernization and economic activity, and increasing federal exposure to commercially structured, revenue-dependent airport assets that may carry higher credit risk and weaker public-purpose alignment; that trade-off forces choices about underwriting rigor, program capacity, and how to define public benefit.
The bill resolves ambiguity about whether airport equipment and revenue-generating, non-public facilities can receive TIFIA assistance, but it leaves important implementation questions open. DOT will need to revise underwriting procedures to evaluate equipment leases, concession-backed revenue streams, and private-access facilities—assets that often have different cash-flow profiles and legal structures than traditional public highway projects.
The statutory swap from 'eligible project costs' to 'a Federal credit instrument' signals an intent to assess the credit product itself, but the statute does not define the metrics, discounting assumptions, or minimum covenants DOT should require for these kinds of airport financings.
Lowering waiver hurdles for airport projects reduces friction for applicants but creates incentives to structure projects to fit the §601(a)(12)(G) carve-out. The lack of definitions for terms such as 'equipment' and 'not publicly accessible' invites disputes about scope: does 'equipment' include leased ground-handling assets, IT systems, or movable security equipment?
How will the bill interact with existing FAA rules on airport revenue use, Passenger Facility Charges (PFCs), and grant assurances that limit certain commercial uses? Finally, raising the small-loan threshold to a $100 million loan amount increases program reach but also shifts subsidy calculations and crowding risks; without corresponding appropriations or clarified prioritization, DOT may face tougher decisions on which projects to support.
