State agencies and state and regional public authorities must install the best available retrofit technology to reduce air pollutant emissions on all heavy-duty diesel vehicles that they own, operate, or lease on or before December 31, 2019. Heavy-duty diesel vehicles that are retired from use in the state on or before December 31, 2020, may be granted a waiver from this requirement.
