Off-Road Technology Workshop Presentations

This page last reviewed December 9, 2003

At the March and October 1998 public hearings, the Board requested that the staff prepare a review of technology development for the various off-road mobile sources. The review is tentatively scheduled to be presented to the Board in the autumn of 2000. At this time, staff has scheduled workshops to enable interested parties to present information relevant to that review.

On February 2 and 3, the staff of the Off-Road Controls Section held the initial workshops for its upcoming report to the Board on off-road emission control technologies. A total of 14 presentations were given by industry members regarding technologies that could be used to reduce emissions from off-road engines, in the near or long term.

February 2 was dedicated to the discussion of spark-ignition engine emission technologies. Nine speakers gave presentations for an industry audience of about 60 people, click here for a list of the attendees (Excel - 19K) or (Acrobat - 7K). February 3 was dedicated to the discussion of compression-ignition engine emission technologies. Five speakers gave presentations for an industry audience of about 50 people.
