Publication Summary

This annual report summarizes statewide air quality trends and programs in 1997. 1997 brought many changes and challenges for those concerned with Washington State′s air quality. Several areas that formerly did not meet air quality standards were either redesignated as meeting standards, or were proposed for redesignation. The federal Environmental Protection Agency (EPA) adopted new federal standards for two air pollutants, spurring changes in the way air quality agencies monitor and control those pollutants. The Department of Ecology′s Air Quality Program conducted an evaluation of its vehicle Emission Check Program to determine how to achieve maximum air quality benefits with minimum public impact. And Ecology began an initiative to improve the ways we protect and enhance visibility in Washington′s scenic areas.
