Key Points

This bill lets big-city transit agencies decide, for certain smaller or routine projects, that they don’t need a full federal environmental review.
If a local agency takes on this power, it also takes on the legal risk—meaning lawsuits or penalties would hit the agency, not the federal government.
Agencies must prove they have the staff and know-how to do the reviews, and they must sign an agreement with the federal government that can last up to 3 years (or 5 years after 10 years of experience).
The federal government can step back in and take the job back if the agency isn’t following the rules, after a warning and at least 120 days to fix problems.
Supporters say this could speed up transit upgrades like station work or bus facility projects; critics may worry it weakens oversight and public input.

After the bill becomes law

Eligible big-city transit agencies decide whether to opt in and ask to take on categorical exclusion duties

If your local transit agency opts in, some smaller transit projects may start construction sooner because the agency can make certain early review decisions itself

Before each memorandum of understanding (MOU) is finalized

Public notice and comment happens before each transit agency signs an agreement with the Secretary

Residents may get a specific window to read the proposed agreement and submit comments before the transit agency takes on these responsibilities

Once the agency is approved and the MOU is executed

Transit agency and the Secretary sign an MOU (up to 3 years, renewable) setting rules and when the Secretary can take control back

This is the “go-live” moment for that agency—after this, the local agency (not the federal government) is on the hook for the assigned review decisions

Soon after an MOU starts

Agencies begin making categorical exclusion decisions using federal criteria and making information publicly available

You may see project documents posted more directly by the transit agency; smaller projects could move from planning to construction faster

Any time after responsibilities are assigned, if compliance issues occur

If problems are found, the Secretary can issue a noncompliance notice and give at least 120 days to fix it

Projects could slow down if the transit agency isn’t following the agreement; there is a built-in chance to correct issues before the authority is pulled back

Any time after opting in, with 90 days notice

An agency can choose to stop participating by giving 90 days notice

If your transit agency opts out later, future projects may go back to the federal process for these decisions, which could change timelines again

After an agency has participated for at least 10 years

Long-running participants (10+ years) can move to 5-year MOUs

In places where this runs smoothly for many years, the process could become more stable and predictable, with fewer renewals to worry about
