Representatives from the Air Resources Board and the Associated General Contractors (AGC) of America trade organization recently agreed on proposed changes to the state’s landmark “off-road” regulation that will offer affected businesses additional time and more flexible options for compliance.

“This marks a new chapter for California and its effort to clean up emissions from diesel engines. We applaud the AGC for showing leadership on this issue and recognizing that California needs to control all sources of diesel emissions,” said ARB Chairman Mary Nichols.
