The South Coast Air Quality Management District convened an In-Use Diesel Engine Emissions Forum and Technical Roundtable to discuss issues related to recent studies of emissions measured from in-use, heavy-duty diesel vehicles.  The objective of the meeting was to develop a better understanding of the uncertainties of in-use, heavy-duty diesel vehicle emissions relative to the preparation of the emissions inventory to be used for the 2007 revision of the Air Quality Management Plan.

Technical experts representing regulatory agencies, academia, and engine manufacturers who have conducted research on this topic provided focused presentations.  A technical roundtable discussion by these experts was conducted.  Public questions and comments were encouraged following the roundtable discussion.

In attendance were major stakeholders, vehicle manufacturers, fleet operators, state and federal regulatory agencies, environmental and community organizations, and other interested parties.
