CAA

I

Comprehensive Area Assessment (CAA)

England, Wales

A new approach that will provide the first independent assessment of the prospects for local areas and the quality of life for people living there. It will assess and report how well public money is spent and will ensure that local public bodies are accountable for their quality and impact. CAA will replace Comprehensive Performance Assessments from April 2009.

II

Clean Air Act (CAA)

USA

A federal law designed to control emissions of air pollutants throughout the US with National Ambient Air Quality Standards (NAAQSs) (42 U.S.C. §§ 7401-7661). The CAA creates health-based standards to determine safe pollutant levels and technology-based standards to measure industries' pollution reduction requirements. States must apply the CAA's standards by creating a State Implementation Plan (SIP). An SIP must provide a system for determining whether Environmental Protection Agency standards have been achieved and set up an enforcement program.
