Maine's Clean Diesel Program

The US Congress passed the Diesel Emission Reduction Act (DERA) in 2005 and DERA grants were reauthorized in 2010. The intent of DERA is to reduce public health risk from exposure to harmful diesel exhaust (off-site) and target areas of poor air quality. DERA was designed to reduce diesel emissions from existing diesel fleets that do not meet federal emission standards. The U.S. Environmental Protection Agency (EPA) is responsible for overseeing and distributing DERA funds. EPA has additional information about the federal DERA program on their national clean diesel website. According to EPA, every $1 dollar spent on DERA upgrades has resulted in $13 worth of health and environmental benefits.

There are four different pools of funding within DERA, each receiving a percentage of the total DERA funds appropriated by Congress each year: National Clean Diesel Funding Assistance Program, 60%; State Allocated DERA Funding, 30%; SmartWay Innovative Finance Program, 6%; and Emerging Technology Program, 4%.

DERA funding sources

State Allocated DERA Funding

Approximately 30% of the DERA funding is allocated to the State DERA Program which is non-competitive funding divided evenly among all fifty states, the District of Columbia and U.S. territories. The Mobile Sources Section of the Bureau of Air Quality is responsible for implementing and overseeing Maine's allocated funding. For more information, contact Lynne Cayting (207) 287-7599.

The funding must be used to develop grant, rebate or low cost revolving loan programs to fund clean diesel projects. Examples of projects funded by the Maine Clean Diesel Program include EPA or California Air Resources Board (CARB) verified idle reduction retrofits, the incremental cost difference for alternative fueled vehicles, marine engine replacements and early vehicle replacements.

National Clean Diesel Funding Assistance Program

The National Clean Diesel Funding Assistance Program (off-site) is a competitive grant program. Approximately 60% of the DERA funding is allocated to this pool of funding each year. The following entities are eligible to apply for funding under this program: regional, state, local or tribal agencies or port authorities with jurisdiction over transportation or air quality and nonprofit organizations or institutions that represent or provide pollution reduction or educational services to persons or organizations that own or operate diesel fleets, or have as their principle purpose, the promotion of transportation or air quality. Non-eligible entities are allowed to partner with an eligible entity to apply for a project, however the eligible entity must submit the application to EPA and assume responsibility for the project. For more information, contact Lynne Cayting (207) 287-7599.

The following types of projects are eligible uses of funding through this program: EPA or CARB verified emission control retrofits, EPA or CARB verified idle reduction technologies, the incremental cost difference for alternative fueled vehicles, EPA certified engine repowers and early vehicle replacements.

In past years the Mobile Sources Section has partnered with public and private fleet owners, as well as non-profit organizations. Typically, the Mobile Sources Section invites interested fleet owners in areas that receive a high quantity of air pollution from diesel fleets, including ports, school yards/bus depots, rail yards, and construction sites.
