The U.S. Environmental Protection Agency (EPA) periodically reviews and establishes health-based national ambient air quality standards (also referred to as NAAQS) for ozone, particulate matter, and other criteria air pollutants guided by the Clean Air Act (CAA). The CAA requires areas designated as nonattainment for these standards to develop Air Quality Management Plans (AQMPs or plans). AQMPs are regional blueprints for achieving air quality standards and healthful air and represent a comprehensive analysis of emissions, meteorology, regional air quality modeling, regional growth projections, and the impact of control measures. Below is a list of plans developed to address various CAA requirements.
This Plan, adopted in December 2019, was developed to address "extreme" area requirements for the 1997 8-hour ozone standard related to Clean Air Action section 182(e)(5).
This Plan, adopted in December 2022, was developed to address attainment of the 2015 8-hour ozone standard.
This Plan, adopted in March 2017, was developed to address attainment of multiple ozone and PM2.5 standards.
