The funds are part of the joint effort between EPA and New England state to leverage significant resources to reduce diesel emissions, improve public health, and promote clean diesel technology.
The fine particles in diesel exhaust pose serious health risks, including aggravated asthma and other respiratory symptoms.
The six states have planned for replacement projects that cover all transportation categories, from school bus replacements to marine repower and construction engine upgrades.
EPA has also provided $2m funds to New England organizations through the National Clean Diesel competitive program.
