The U.S. Environmental Protection Agency (EPA) has announced the availability of approximately $7 million in rebates to public school bus fleet owners to help them replace or retrofit older school buses. Upgrading buses with older engines reduces diesel emissions and improves air quality.

EPA standards for new diesel engines make them more than 90 percent cleaner than older ones, but many older diesel engines still in operation predate these standards. Older diesel engines emit large quantities of pollutants such as particulate matter (PM) and nitrogen oxides (NOx), which have been linked to serious health problems such as aggravated asthma and lung damage.

EPA will accept applications from Sept. 29 to Nov. 1, 2016.

This is the fourth rebate program to fund cleaner school buses offered under the Diesel Emission Reduction Act (DERA) reauthorization. Nearly 25,000 buses across the country have already been made cleaner as a result of DERA funding.
