Air Quality Attainment Plans
The U.S. Environmental Protection Agency (EPA) periodically reviews and establishes health-based national air quality standards (also referred to as NAAQS) for ozone, particulates, and other criteria air pollutants guided by the Clean Air Act. The District
has adopted numerous air quality attainment plans that identify measures needed in the Valley to attain the increasingly stringent
federal standards. Over the past decades, the District has implemented over 670 emissions control measures for stationary and area sources under its jurisdiction. Similarly, the California Air Resources Board (CARB) has adopted regulations for mobile sources. Together, these efforts represent the nation’s toughest air pollution emissions controls.
The District’s plans include emissions inventories that identify sources of air pollutants, evaluations for feasibility of implementing potential opportunities to reduce emissions, sophisticated computer modeling to estimate future levels of pollution, and a strategy for how air pollution will be further reduced. District plans also include innovative alternative strategies for accelerating attainment through non-regulatory measures such as incentive programs; technology advancement programs; the District’s legislative platform; community outreach and education programs; and additional strategies to evaluate technology advancements as they become available into the future.
As a result of the District’s stringent and comprehensive air quality management strategy along with significant investments made by Valley businesses and residents, PM2.5 and ozone levels are now at historically low levels and providing Valley residents with the associated health benefits.
