As far as I know the state is not sending out any notices of violation to anyone. It would be a bureaucratic nightmare and possibly cause wholesale rioting and civil unrest.
The DEQ requirements are different from the DMV requirements. The DEQ on road testing claims it applies to 1968 and newer "Virginia registered vehicles that are primarily operated within and through the Northern Virginia area, regardless of registration address or garage location." However the DMV Requirement is only for vehicles 25 years old and newer, registered in the counties of Arlington, Fairfax, Loudoun, Prince William, or Stafford, and cities of Alexandria, Fairfax, Falls Church, Manassas or Manassas Park.
Essentially the DEQ on-road testing applies to many more vehicles than the DMV requirement for emissions testing. Who is going to arbitrate where a vehicle is primarily operated, and how do they propose to do so? Does the rest of the state even have facilities to test emissions? For example if someone from Southwest Va gets a notice of violation while driving in Fairfax, where would they take their car locally for a "Confirmation Test"? The link to virims.com is dead. Furthermore, I doubt the state even has appropriated the funds to reimburse gas stations for the free confirmation tests.
If they ever did actually mail any of these notices, the Rapidpass test stations would rapidly become target practice for enraged citizens.
