Control Techniques Guidelines (CTG)
Definition - What does Control Techniques Guidelines (CTG) mean?
Control Techniques Guidelines (CTG's) are materials issued by the U.S. Environmental Protection Agency (EPA) to provide the EPA's suggestions on managing emissions from volatile organic compounds (VOC) that arise from a certain source in a non-attainment area. The EPA has been allowed by the Clean Air Act (CAA) to issue CTGs in the place of National regulations when EPA deems that CTGs will be as effective or more effective at reducing the emission as a National regulation.
Safeopedia explains Control Techniques Guidelines (CTG)
A U.S. state that has non-attainment areas must examine the suggestions outlined in the CTGs as provided by the EPA and decide whether it should modify existing National regulations to remain in sync with the CTGs. Once a state puts into effect a new, adjusted regulation that is in sync with EPA's CTGs, they must submit the regulation back to EPA for approval before it is implemented by the state.
