Analyze Trends: State Air Dashboard

The Clean Air Act (CAA) authorizes EPA to regulate air pollution from stationary sources like chemical plants, utilities, and steel mills. EPA delegates much of their CAA authority to state, local and tribal agencies. To manage the national CAA stationary source compliance monitoring and enforcement program, EPA requires that delegated agencies regularly report data on the type of facilities within their jurisdiction and activities conducted, such as, compliance evaluations, compliance determinations, and enforcement actions. The dashboards provide an easy-to-use summary of activities to answer questions like: which facilities are regulated, how many have been evaluated, and how many have alleged violations and have been subject to enforcement.

State counts may include facilities where a local control agency has been delegated the authority to enforce the Clean Air Act. Therefore, activities conducted by the local control agency are included in the state counts.

Due to the transition between CAA national data management systems, the Performance View of the Air Dashboard has not been updated since January 31, 2015. EPA is reviewing options for displaying more recent data. Differences in Activity View data between FY14 and FY15 may be apparent due to the different data sources – the legacy data system and the current system. Additionally, some states are still establishing complete data transfer connections to the current system, in which case their full data sets may not yet be represented in ECHO.

State Review Framework

The State Review Framework (SRF) is a tool used by EPA to consistently assess each state and local agencies' enforcement of the Clean Air Act, the Clean Water Act, and Hazardous Waste laws; and the SRF tracks recommendations made by EPA for state and local agencies to improve their compliance and enforcement programs.

Common Questions

What are expectations related to compliance monitoring within states?What types of facilities are regulated by the Clean Air Act?Where does the data come from - is the data frozen, or does it use production data from the systems?How can I find CAA compliance and enforcement information for a specific facility?Where can I find emissions and chemical release data for a facility?How can I find air quality information for an area of interest to me?Does EPA require that all violations or permit deviations at every air emission source be reported to them?How can I download detailed information about compliance and enforcement activity?

About the Data and Assessing State Performance

State performance is a complex and difficult matter to analyze and explain. Data alone cannot provide a complete picture of performance. Many states have issues with data completeness and accuracy, and without investigation and program knowledge, data can be misleading or misinterpreted. Often, there is important context around data that must be taken into account to provide an accurate picture. For example, not all activities and violations may be reported, some states are not authorized to run programs, current year data may still be in the process of being reported, and states may have alternative inspection plans. EPA uses data, like the information here, as a starting point for assessing state performance, but not as the sole measure of performance. More in-depth program reviews (see State Review Framework Reports) are used to identify needed state program improvements. While file reviews and management discussions can add to our understanding, the many layers of context and information make it difficult to portray performance in a consistent and transparent way.


Activities and Violations

Data shown in the State Dashboards are based on data reported to EPA and may not reflect all compliance monitoring/inspections, enforcement or the full extent of noncompliance within a state. State environmental agencies may have more information on activities and noncompliance within their state on their agency websites. Links to state agency websites are provided below each State Dashboard.


Some states/territories do not have authorization/delegation to enforce any or all regulations implemented under the CAA, CWA and RCRA. In these instances, when State is selected as the implementing Agency, it may appear that no activity was conducted. Activity in these states/territories may be displayed when EPA is selected as the implementing Agency. Where this occurs is:

  • Air: American Samoa, Guam and Northern Mariana Islands
  • Hazardous Waste: Alaska, American Samoa, Guam, Iowa, Puerto Rico, Virgin Islands
  • Water: Alaska, American Samoa, Guam, Idaho, Massachusetts, New Hampshire, New Mexico, Puerto Rico

Current Year

The most recent federal fiscal year may not show a complete data set because it has not yet been verified or the year is not completed.
