Enhanced Stage I Vapor Recovery

Georgia Air Quality Rule 391-3-1-.02(2)(rr)

Enhanced Vapor Recovery (EVR) is a gasoline vapor recovery system which recovers at least 98% of the emissions at gasoline dispensing facilities during bulk gasoline deliveries.

If you own a gasoline dispensing facility located in Barrow, Bartow, Carroll, Hall, Newton, Spalding, or Walton counties, you must have EVR installed now.

If you own a gasoline dispensing facility located in Cherokee, Clayton, Cobb, Coweta, DeKalb, Douglas, Fayette, Forsyth, Fulton, Gwinnett, Henry, Paulding or Rockdale, your facility must have converted to EVR by May 1, 2012. Beginning June 1, 2008, new facilities in these areas were required to install EVR.

Beginning June 1, 2008, new facilities in these areas were required to install EVR.  Please note that facilities in these three counties that existed prior to June 1, 2008 must continue to operate and test their stage I systems.

Beginning January 10, 2010, a federal rule applied to all other Georgia counties. The federal rule states that if you are an existing station and sell more than 100,000 gallons of gasoline a month, you will be required to install a regular vapor recovery system. See EPA Rule "CCCCCC".

Georgia Air Quality Rule 391-3-1-.02(2)(rr) is part of the plan to improve air quality in Georgia. Air quality in the metro Atlanta region has been designated by the U.S. EPA as “non-attainment” for ozone. This means that the air does not meet federal air quality standards and can be unhealthy to breathe.

Fumes from gasoline contribute to ozone pollution. Some fumes are toxic. Vapor Recovery limits the amount of fumes and toxic compounds emitted into the air.

The Stage I Vapor Recovery System

Components of a Stage I system

Components of a Stage I System

  • A drop tube as recommended by the system manufacturer that is within 6 inches from the bottom of the tank
  • Tank vents at least 12 feet high from the ground with an approved pressure/vacuum vent valve
  • A drain valve for the spill bucket
  • Poppetted Vapor Adaptor 

EVR is different from the regular Stage I Vapor Recovery because it also has the following:    

  • Identifiable rotating adaptors for gasoline and vapor
  • Integrated drain bucket, drop tube and drain valve
  • Specialized P/V valve
  • Spill bucket for vapor adaptor


  • All components and installers must be certified by the manufacturer.
  • ​You cannot mix and match EVR parts.

Common Questions Concerning EVR

  • Who can install my EVR?
    Only certified, trained technicians are allowed to install your EVR. Each system’s website has a list of certified technicians from which you can choose.
  • Once my EVR system is installed, what am I required to do?
    Your new system will need to be tested by a trained, certified tester. For a list of approved testers, call Temitayo Ewemoje, GA EPD, at (404) 623-2929.
  • What about EPD inspections?
    The Environmental Protection Division (EPD) periodically will conduct unannounced inspections to ensure that your EVR was properly installed and tested and is being maintained correctly.

Testing and Maintenance Schedule

  • Certification testing is required within 30 days of system installation.
  • Recertification of existing regular vapor recovery system is every 12 months thereafter.
  • Recertification of EVR Stage I is required every 12 months following the initial certification.
  • EVR Stage I installers and testers must be certified by the manufacturer of the system installed.
