The Engines and Fuels Unit evaluates and develops strategies to reduce harmful emissions from on-road and nonroad vehicles and area sources. The Unit implements and enforces the Stage I and II Vapor Recovery, Gasoline Transport, Gasoline Marketing, Consumer and Commercial Products, Heavy-Duty Diesel Engine Requirements, and Clean Fueled Fleets rules. The Engines and Fuels Unit administers the Low Emission Vehicle Certification and Voluntary Alternative Fuels Programs. In addition, the Unit focuses on voluntary efforts to reduce diesel emissions including the Georgia Retrofit and Idling Reduction Programs.
Engineslogo Alternative Fuels Georgia Gasoline Marketing Consumer Commercial Products GA Retrofit Program Idling Reduction Stage I Vapor Recovery Stage I Transport Stage II Vapor Recovery GA EPD Gasoline Vapor Recovery is the system used to capture vehicle refueling emissions transporting the vapor back to the tank and collecting them during fuel delivery to the gasoline dispensing facility.The system recovers at least 98% of the emissions at gasoline dispensing facilities during gasoline drops. Fumes from gasoline contribute to ground level ozone pollution and may contain carcinogens. The Enhanced Vapor Recovery (EVR) processlimits the amount of fumes and toxic compounds emitted into the air. In some areas of Georgia, you are required to install EVR Stage I systems. Please see individual pages regarding gasoline vapor recovery as it applies to the following:
Georgia Diesel Emission Reduction (GaDER)
  • Georgia Retrofit Program
    The Georgia Retrofit Program began as a pilot program designed to provide funding assistance that helps school systems in the 20-county metro Atlanta non-attainment area to reduce emissions from their school bus fleets. With over 2000 school buses retrofitted to date, this program has been expanded to cover the state of Georgia. Environmental Protection Division (EPD) staff continue to apply for grant funding to help school systems, public and private companies to retrofit their buses and vehicle fleets.

  • Idle Reduction
     Eliminating unnecessary idling of heavy-duty vehicles is a reasonable approach to improving air quality that can also save money. EPD is actively encouraging voluntary idle reduction initiatives.

  • The Georgia Heavy Duty Diesel Engine Rule.
    Georgia adopted the California Heavy Duty Diesel Engine Regulations in 2001. Diesel vehicles 14,001pounds or larger must meet the California Heavy Duty emissions standards. In March each year, dealerships are required to report the number of vehicles they have imported or sold in the state. EPD staff randomly inspect dealerships to ensure that only compliant engines are sold in Georgia.

Alternative Fuels & Low Emission Vehicle Tax Credits
Alternative fuels can be cleaner for the environment. The State of Georgia offers an incentive for people who purchase an alternative fuel vehicle. If your vehicle is registered in Georgia and it is powered solely by an alternative fuel, you may be eligible for one of the following tax credits:

  • Low-Emission/Alternative Fuel Vehicle*
  • Vehicle Conversion
  • Zero Emission Vehicle
  • Electric Vehicle Charger - eligible for business enterprises

*Hybrid vehicles do not qualify. The vehicle must run only on alternative fuel.

Clean Fuels Fleet (CFFP)

The Clean Fueled Fleets Program (CFFP), developed as a part of the Clean Air Act Amendments, is intended to improve air quality by encouraging the use of cleaner burning vehicles. The CFFP requires a percentage of new fleet vehicle purchases to be Clean Fueled Vehicles (CFVs) if your business is located in Cherokee, Clayton, Cobb, Coweta, DeKalb, Douglas, Fayette, Forsyth, Fulton, Gwinnett, Henry, Paulding, or Rockdale counties.

The purpose of the Clean Fueled Fleets Program (CFFP) is to place moreCFVs on the road, and to help Georgia reduce ozone emissions and improve air quality. Please note that light duty and heavy duty vehicles purchased since the 2005 model year meet clean fueled vehicle standards.
Consumer and Commercial Products Rule
If you sell windshield wiper fluid in Cherokee, Clayton, Cobb, Coweta, DeKalb, Douglas, Fayette, Forsyth, Fulton, Gwinnett, Henry, Paulding, or Rockdale counties, and if your business is located in one of the above counties, you are subject to Air Quality Rule 391-3-1-.02(2)(aaa) Consumer and Commercial Products.		 The Gasoline Marketing Rule was created to ensure the distribution of low sulfur and seasonal low Reid Vapor Pressure (RVP) gasoline into the metro Atlanta ozone nonattainment area. This cleaner-burning gasoline helps reduce emissions of sulfur and volatile organic compounds (VOCs) from motor vehicles, both of which are precursors to ozone development. The Gasoline Marketing Program's fuel control area encompasses 45 counties in and around metro Atlanta.
