NJ WorkClean: Diesel Modernization Grant Program

Summary

The NJ WorkClean Diesel Modernization Grant Program aims to improve air quality by funding diesel-to-diesel and diesel-to-electric projects. It targets older diesel vehicles and equipment that contribute to air pollution, particularly in overburdened communities. This reimbursement program supports replacing marine engines and non-road diesel vehicles while promoting the electrification of on-road diesel vehicles, such as school buses and garbage trucks, to enhance public health and environmental standards.

Overview

NOTE: Program staff will reach out within 5 to 10 business days after submittal of your project proposal to let you know the status and if additional information is needed. Submittal of a project proposal does not guarantee that it will be selected for funding. Purpose of Funding To provide funding for both diesel-to-diesel and diesel-to-electric projects designed to improve air quality, especially in areas that do not meet the national air quality standards. Older, low-quality diesel vehicles and equipment operating in the State contribute heavily to air pollution, negatively affecting the health of our residents, particularly in overburdened communities.  Diesel engines emit a complex mixture of air pollutants, comprised of both solid and gaseous material. The visible emissions you can see in diesel exhaust are known as particulate matter. These include many carbon particles (also called soot), as well as gases that become visible as they cool. Diesel particulate matter (diesel PM) has been identified as having the potential to cause cancer, as well as many other adverse health effects. In addition to particulate matter, emissions from diesel-fueled engines include over 40 other cancer-causing substances. The Bureau of Mobile Sources’ Diesel Modernization Program is primarily a diesel replacement program. This program utilizes State and Federal funding to replace both marine engines and non road diesel vehicles – anything from ferry vessels to backhoe loaders and bulldozers. Contingent upon open solicitations, the program also works with both municipalities and private entities to electrify on-road diesel vehicles, such as school buses, garbage trucks, and port equipment. Funding This is a reimbursement program:  Funds will only be disbursed after the project has been completed and fully paid for by the applicant.
