Analyze Trends: State Water Dashboard

The Clean Water Act National Pollutant Discharge Elimination System (NPDES) authorizes EPA to regulate discharges to waters of the United States. EPA delegates much of the CWA authority to state, territory, and tribal agencies. The State Dashboard provides an overview of Clean Water Act regulatory oversight activities of authorized agencies and EPA. The dashboards provide an easy-to-use summary of key activities to answer questions like: which facilities are regulated, how many have been inspected, how many have alleged violations, and how many enforcement actions have been taken.

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 is the NPDES Permit Program?Where does the data come from - is the data frozen, or does it use production data from the systems?What are the types of facilities regulated by EPA and the states under the CWA NPDES program?Can I search for a company or particular facility to see if they have violations?Where can I find water quality data for the watershed where a facility with an NPDES permit is located?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. Some 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 jurisdiction. Authorized environmental agencies may have more information on activities and noncompliance within their area on their websites. Links to agency websites are provided below each State Dashboard.


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

  • Air: American Samoa, Guam, and Northern Mariana Islands
  • Hazardous Waste: Alaska, American Samoa, Guam, Iowa, Puerto Rico, Virgin Islands
  • Water: Alaska, American Samoa, District of Columbia, Guam, Idaho, Massachusetts, New Hampshire, New Mexico, Puerto Rico, and all tribes other than Navajo Nation

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.

New Jersey CWA

Please note that New Jersey was not supplying EPA with data about its Clean Water Act discharge program, as it did not convert to the current program data system (ICIS-NPDES) until March 2018. EPA copied New Jersey's data from the old data system on November 29, 2012. This allowed users to see the list of regulated facilities and associated historical activities; however, subsequent state activities were not being reported until recently.
