Diesel engines have been and will likely continue to be a vital
workhorse of our economy, powering large trucks, busses, farm, railroad,
marine and construction equipment. However, diesel engine exhaust
contains harmful pollutants in a complex mixture of gases and particulates.
We are all potentially exposed to pollution from diesel vehicles.
Reducing pollution from heavy-duty trucks and buses is part of the
nation's clear air plan. Steps are being taken in Pennsylvania and
nationwide to make this equipment less polluting.

Diesel Idling Information
Trucks and buses waste fuel and create emissions
from unnecessary idling. Improved management and technology can
cut unnecessary idling.

The Mid-Atlantic Regional Air Management Association (MARAMA) and U.S. EPA Region III have established the Mid-Atlantic Diesel Collaborative, a new regional effort to reduce diesel related emissions. Pennsylvania invites the participation of fleet operators of all kinds, local governments, equipment vendors and distributors and others interested in reducing diesel emissions.
Rules have been developed by EPA for the first phase of a two-part
strategy to significantly reduce harmful diesel emissions from
heavy-duty trucks and buses, as well as, new quality requirements
for diesel fuel to enable the use of a new generation of emission
control technologies for diesel engines.
