The U.S. Environmental Agency says it has received commitments to clean up 13,500 diesel trucks and buses by next January as part of its Voluntary Diesel Retrofit Program.

The program, announced last year, encourages industry, community groups, and state and local officials to implement retrofit projects to reduce emissions of older equipment.
Funding is available from a variety of sources, including EPA, state and local grants.
So far, Boston, New York, Seattle and Washington, D.C., are participating in the project. New Jersey and California are instituting statewide programs.
In Washington, D.C., Waste Management will retrofit 10 recycle trash trucks with
catalytic converters. That project is funded by a grant from EPA’s Office of
Transportation and Air Quality. In New Jersey, the state Department of Transportation plans to retrofit older, publicly owned trucks and buses with oxidation catalysts. Money will come from Congestion Mitigation Air Quality funds, a program managed by the U.S. Department of Transportation’s Federal Highway Administration.
