- What it does
- The Diesel Emissions Reduction Act, 42 U.S.C. 16131 et seq., as amended, authorizes EPA to award assistance agreements to states and territories to develop and implement such grant, rebates, and loan programs in the states and territories as are appropriate to meet state and territory needs and goals relating to the reduction of diesel emissions. In providing grants, rebates, and loans under this program, states must give priority to projects which: maximize public health benefits; are the most cost-effective; serve areas with the highest population density, that are poor air quality areas (including nonattainment or maintenance of national ambient air quality standards for a criteria pollutant; Federal Class I areas; or areas with toxic air pollutant concerns); serve areas that receive a disproportionate quantity of air pollution from diesel fleets, including truck stops, ports, rail yards, terminals, construction sites, schools, and distribution centers or that use a community-based multi-stakeholder collaborative process to reduce toxic emissions; will only include a certified engine configuration or verified technology that has a long expected useful life; maximize the useful life of any certified engine configuration or verified technology used or funded by the eligible entity; and conserve diesel fuel.
- Who benefits

How to read these numbers
- Committed through this program
Money committed under this assistance listing (its CFDA program), counted in the year each action happened.
- How it's paid
Most programs pay out one way — a grant, or a direct payment to individuals; the flow bar only appears when a program genuinely mixes types.
- Some recipients aren't itemized
For entitlement programs like Social Security and Medicare, the government reports one aggregate instead of naming tens of millions of people, so the recipient roster isn't part of the public record.
- Awards, counted once
An award count is the number of distinct awards with at least one action that year — each counted once, however many times it was amended.
- The colored bars
Every bar on this page splits by how the money moves:
