1970-12-31Clean Air Amendments of 1970 (Public Law 91-604)
★The Clean Air Amendments of 1970 (Public Law 91-604) strengthened the federal Clean Air Act by expanding research into the health and environmental effects of air pollutants, increasing grant funding to state and regional air pollution control agencies, and establishing a framework for national ambient air quality standards. The law required the EPA Administrator to publish and maintain a list of harmful air pollutants and issue scientific criteria for each within 12 months of listing. It also directed states to take primary responsibility for meeting national air quality standards within their borders through mandatory implementation plans. -

2022-09-01Destination 2030: Air quality conformity
This document outlines the air quality conformity analysis for Destination 2030, the long-range transportation plan for the central Puget Sound region, ensuring that planned transportation projects meet federal and state clean air standards. The region, previously designated as a nonattainment area for carbon monoxide, ozone, and particulate matter, was redesignated as a maintenance area after meeting federal air quality standards, with EPA approvals granted between 1996 and 2001. The conformity process involved consultation with agencies including the EPA, FHWA, and Washington State Department of Ecology to ensure new transportation projects do not cause or worsen air quality violations.
