Reasonably Available Control Technology (RACT)
Best Available Retrofit Control Technology (BARCT)

This page last reviewed April 21, 2010


The California Clean Air Act of 1988 requires, among other things, that local air quality management and air pollution control districts (districts) develop attainment plans to achieve the state ambient air quality standards as expeditiously as practical. These plans must include regulations that require control technologies for reducing emissions from existing sources. RACT / BARCT determinations are developed to aid districts in developing regulations to attain and maintain the state ambient air quality standards. The determinations also promote consistency of controls for similar emission sources among districts with the same air quality attainment designations.
