NESCAUM and the air quality programs in the Northeast States and Caribbean territories are represented on the NEDC Steering Committee, plus they are eligible recipients of federal grants under the Diesel Emissions Reduction Program. However, EPA has sole responsibility for evaluating, ranking and awarding grant funds under this competitive process. Grants are evaluated and awarded by EPA according to the criteria outlined in the Request for Proposals, and based on the merits of individual applications, without regard to a project sponsor's affiliation with the NEDC. Once EPA announces a grant competition, EPA staff do not participate in NESCAUM and state discussions on grant proposals. Likewise, when EPA program staff evaluate grant proposals, NESCAUM and state staff are excluded from the evaluation, selection and award process. These procedures help to ensure a fair process.

Diesel Emissions Reduction Act (DERA) National Grants
Now Open: 2021 Request for Applications
Deadline to Apply - March 16, 2021 (11:59 p.m. ET)

The U.S. Environmental Protection Agency (EPA) is excited to announce the availability of approximately $46 million in Diesel Emissions Reduction Act (DERA) grant funds to support projects aimed at reducing emissions from the nation's existing fleet of older diesel engines. Under this competition, between 40 and 70 awards are anticipated.

Eligible Entities

Eligible applicants include regional, state, local or tribal agencies, or port authorities, with jurisdiction over transportation or air quality. Nonprofit organizations may apply if they provide pollution reduction or educational services to diesel fleet owners or have, as their principal purpose, the promotion of transportation or air quality.

Incentives and Funding Opportunities for Idle Reduction Projects

Various federal, state, and nonprofit organizations provide funding that can be used for the reduction of emissions from long-duration truck and locomotive idling.

Congestion Mitigation Air Quality (CMAQ) Funds

The U.S. Department of Transportation's CMAQ program provides funds to state DOTs, MPOs, and transit agencies to invest in projects that reduce air pollution from transportation-related sources.

The CMAQ program is one source of funds for Transportation Control Measures (TCMs) employed for the purposes of reducing congestion and improving air quality.

Port Authority Truck Program

The Port Authority of New York & New Jersey Regional Truck Replacement Program (TRP) is a special first-come, first-served limited offer to provide grants and financing to eligible truck owners to help them purchase newer, cleaner and more environmentally-friendly trucks.


  • Own a drayage truck (Class 8, 33,001 pounds gross vehicle weight rating (GVWR) and higher) equipped with an engine Model Year 1993 or older
  • Demonstrate a history of regularly calling to the Port of NY & NJ marine terminals (approximately 200 times in the last 12 months)
  • Be willing to scrap old drayage truck
  • Possess a valid vehicle registration, license plate, and driver's license
  • Have acceptable credit history and cash flow if applying for low-interest financing

Clean Cities Funding

There are many financial opportunities available. When applying for funding, ask your local Clean Cities coordinator for help. Coordinators can offer sound advice on how to successfully navigate the process to obtain the funding needed to meet petroleum reduction goals.

DERA Grants

The Diesel Emissions Reduction Act (DERA) establishes a voluntary national and state-level grant and loan program to reduce emissions from existing diesel engines through clean diesel retrofits. Emissions from older diesel vehicles and equipment can be reduced between 20 and 95 percent with cost-effective retrofit technology. The EPA estimates that if DERA is fully funded, it would reduce particulate matter emissions by greater than 70,000 tons, generate greater than $20 billion in economic benefit, and return $13 in health, environmental and economic benefits for every one dollar invested. Since the program's creation in 2005, the U.S. EPA has provided $519 million in grants for clean diesel projects.

2012 Reauthorization of Diesel Grants--President Obama Jan. 4 signed legislation (H.R. 5809) reauthorizing grants to state, local, and tribal governments for programs to reduce emissions from existing diesel engines. The bill, passed by the Senate Dec. 16 and the House Dec. 21, authorizes $100 million each year for the grants for fiscal years 2012 through 2016 (244 DEN A-7, 12/22/10). The grants are used to reduce emissions through means such as retrofitting diesel engines with emissions controls. Any funding authorized would still be subject to actual appropriations by Congress.

DERA Rebates

The Diesel Emissions Reduction Act (DERA) of 2010 allows EPA to offer rebates in addition to grants to reduce harmful emissions from older, dirtier diesel vehicles. EPA's DERA Rebate Program has funded vehicle replacements or retrofits for over one thousand vehicles to date. Typically, the rebate application period opens in the fall and projects are completed in less than one year.
