WorkClean Diesel Modernization Grant Program

The WorkClean Diesel Modernization Program is administered by the New Jersey Department of Environmental Protection through its Bureau of Mobile Sources. This program is supported by a combination of state and federal funding sources and is designed to reduce harmful air pollution associated with diesel-powered engines. The initiative reflects the state’s broader environmental and public health priorities, particularly in addressing emissions that disproportionately affect overburdened communities. Diesel particulate matter and associated pollutants have been identified as contributors to cancer and other adverse health outcomes, and this program aims to mitigate those risks through targeted equipment and vehicle upgrades. The primary purpose of the program is to fund projects that replace older diesel engines with newer diesel or electric alternatives. The program focuses on improving air quality by reducing emissions from high-polluting equipment such as marine engines and non-road vehicles, including construction equipment like bulldozers and backhoes. Additionally, the program supports electrification of on-road diesel vehicles, including school buses, garbage trucks, and port equipment, when funding solicitations are available. These efforts are intended to modernize fleets and accelerate the transition toward cleaner technologies. Funding is provided on a reimbursement basis, meaning that applicants must first complete and fully pay for their projects before receiving funds. The types of allowable projects and funding limitations vary depending on the specific funding source assigned to the project. Applicants are informed of these limitations and requirements only after their proposal is selected and matched with a funding source. This structure requires applicants to have sufficient financial capacity to front project costs prior to reimbursement. Eligibility for the program is broad and inclusive, reflecting its goal of widespread environmental impact. Potential applicants include businesses, government entities, nonprofit organizations, educational institutions, and Metropolitan Planning Organizations. However, all applicants must meet specific program qualifications. Notably, this is a replacement-focused program, and applicants must provide details about existing diesel vehicles or equipment that will be decommissioned. Replacement equipment must be similar in type and classification, including comparable gross vehicle weight ratings, to ensure alignment with program objectives. The application process is ongoing, as the program accepts rolling submissions. Applicants can submit project proposals at any time, although competitive solicitations with specific deadlines and requirements may be issued periodically. Applicants who have previously submitted proposals that were not selected may revise and resubmit them during these competitive periods. Program staff review submissions and typically provide a status update or request additional information within five to ten business days after submission. There is no fixed application deadline due to the rolling nature of the program, and no formal pre-application phase is required. However, the timing and structure of competitive solicitations may introduce specific deadlines in certain cases. Because of this flexible structure, the program does not follow a traditional annual cycle. Instead, it operates continuously, with funding opportunities dependent on available resources and targeted initiatives. For additional information or clarification, applicants are encouraged to contact the program directly via email at stopthesoot@dep.nj.gov. Detailed guidance on project types, eligibility requirements, and submission procedures is available through the program’s official webpage. While the program does not guarantee funding for submitted proposals, it provides a structured pathway for entities to contribute to improved air quality and public health outcomes across New Jersey.
