Definitions for "Ambient air quality standards"
Standards required by the Federal Clean Air Act and enforced by the U.S. Environmental Protection Agency that protect public health, provide for the most sensitive individuals, and allow a margin of safety by setting an acceptable level for measured pollutant concentrations. AAQSs cannot take into account the cost of achieving the standards.
