Heavy-Duty Diesel Emission Reduction Project Retrofit/Rebuild Component.
The purpose of this document is to expand the use of retrofit pollution control technologies in heavy-duty engines through the development of consistent guidelines for voluntary retrofit programs. Such programs would be targeted to heavy-duty vehicles not affected by the federal Urban Bus Program and would include control technologies not certified under that program as well as Urban Bus Program certified technologies.
