National Clean Diesel Funding Assistance Program

Sections 792 of the Energy Policy Act of 2005 authorize EPA to award grants and low-cost revolving loans to eligible entities to fund the costs of a retrofit technology that significantly reduces emissions through development and implementation of a certified engine configuration, verified technology,
or emerging technology for buses (including school buses), medium-duty or heavy-duty trucks, marine engines, locomotives, or nonroad engines or vehicles used in construction, handling of cargo (including at port or airport), agriculture, mining, or energy production.

In addition, eligible entities may also use funds awarded for programs or projects to reduce long-duration idling using verified technology involving a vehicle or equipment described above, or the creation of low-cost revolving loan programs to finance diesel emissions reduction projects.

The objective of the assistance under this program is to achieve significant reductions in diesel emissions in terms of tons of pollution produced and reductions in diesel emissions exposure, particularly from fleets operating in areas designated by the Administrator as poor air quality areas.

Funding Priority-Fiscal Year 2008: This program aims to work aggressively to reduce the pollution emitted from diesel engines across the country through the implementation of varied control strategies and aggressive involvement of national, state, and local partners.

Priority shall be given 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, and distribution centers or that use a community-based multi-stakeholder collaborative process to reduce toxic emissions; Include a certified engine configuration, verified technology, or emerging technology that has a long expected useful life; Will maximize the useful life of any certified engine configuration, verified technology, or emerging technology used or funded by the eligible entity; Conserve diesel fuel; and Utilize ultra low sulfur diesel fuel (15 parts per million of sulfur content) ahead of EPA's mandate (for nonroad projects).

Voluntary or elective emission reduction measures shall not be considered "mandated", regardless of whether the reductions are included in the State implementation plan of a State.

Distribution of Funds: 1) not less than 50 percent of funds available for a fiscal year under the DERA National Program shall be provided to eligible entities for the benefit of public fleets; 2) not less than 90 percent of funds available for a fiscal year under the DERA National Program shall be provided to eligible entities for projects using-a certified engine configuration; or a verified technology.3) not more than 10 percent of funds available for a fiscal year under the DERA National Program shall be provided to eligible entities for the development and commercialization of emerging technologies.

Eligibility Requirements

Applicant Eligibility

A regional, State, local or tribal agency or port authority with jurisdiction over transportation or air quality; and a nonprofit organization or institution that represents or provides pollution reduction or educational services to persons or oganizations that own or operate diesel fleets; or has, as its principal purpose, the promotion of transportation or air quality are eligible for assistance under this program.

City, county, or municipal agencies, school districts, and metropolitan planning organizations (MPOs) that have jurisdiction over transportation or air quality are all eligible entities under this program.

Recipients must keep financial records, including all documents supporting entries in accounting records and to substantiate changes in grants available to personnel authorized to examine EPA recipient grants and cooperative agreement records. Recipients must maintain all records until 3 years from the date of submission of the final expenditure reports. If questions, such as those raised as a result of an audit remain following the 3-year period, recipients must retain records until the matter is completely resolved.
