Basic Information about Air Quality TIPs
What is a TIP?
A Tribal Implementation Plan (TIP) is an air quality plan developed by a tribe to help attain and/or maintain national air quality standards () for criteria air pollutants and fulfill other requirements of the Clean Air Act.
Unlike states, tribes are not required to adopt an implementation plan. In the Tribal Authority Rule, EPA recognized that not all tribes will have the need or the desire for an air pollution control program. If a tribe elects not to develop a TIP, EPA will develop a Federal Implementation Plan (FIP) to protect air quality, as necessary.
