RSD Virginia

Virginia Total Screen Program

Commencing operations in 2004, the on-road remote sensing program collects vehicle emissions data in the Northern Virginia I/M area from over one million vehicles annually.

Utilizing a standard "high-emitter" indexing and identification process, ESP identifies vehicles for the Virginia Department of Environmental Quality (VDEQ) so that they can issue official notices to motorists. These notices require motorists to have their vehicle reinspected at an official I/M station within the existing decentralized testing network for emissions verification purposes.

Clean screening and fleet characterization are two additional outputs of the program in Virginia, resulting in the most efficient utilization of RSD, a "Total Screen" program.

VDEQ also utilizes the data collected by ESP to analyze Gross Liquid Leakers (GLLs) through a cooperative evaporative emissions identification program. This program identifies excessive leaks throughout the entire vehicle, not just those emissions from the tailpipe. Managed reduction of these emissions can be even more significant and effective than with that of a standard I/M program.
