The Ohio Environmental Protection Agency has up to $12 million to distribute in the current funding cycle for owners of heavy duty diesel vehicle fleets seeking grants to help reduce diesel emissions.

Summit, Stark, Portage, Medina and Cuyahoga are among the eligible counties.

Projects funded by the Diesel Emission Reduction Grants will help improve air quality through vehicle replacement, repowering engines, retrofitting emission controls or installing anti-idle equipment.

The agency is earmarking $4 million to public transit projects that satisfy statewide needs identified by the Ohio Department of Transportation and $4 million to school bus projects.

Grants of between $50,000 and $1 million will be awarded.

Funding comes from the Federal Highway Administration’s Congestion Mitigation and Air Quality program in Ohio.

Applications must be submitted by Oct. 7 and must demonstrate fleet eligibility, how the proposed project conforms to federal guidelines, and how the applicant will meet the required match of at least 20 percent of the project cost.

Private sector diesel fleets may apply through a public sector sponsor.

An information session for applicants will be held at noon on Sept. 7 at the Ohio Department of Transportation headquarters, 1980 W. Broad St., Columbus.

In addition, conference calls are being offered on Sept. 14 and Sept. 20 to answer applicants’ questions. Frequently asked questions and answers from these sessions will be posted on the program website.

All applications must be submitted online.
