What is this?

NPR and the Center for Public Integrity are making public for the first time a watch list of the chronic violators of air pollution rules. The list was created in 2004 to help Washington crack down on long-term violators that states and regional EPA offices had failed to bring into compliance with the Clean Air Act. NPR and CPI are the first media outlets to obtain and publish the list, as NPR's Elizabeth Shogren reported today on Morning Edition.

Below is a localized version of the map NPR put together that plots more than 17,000 sources of air pollution across the country. You can interact with the map by zooming in and out and clicking on each colored dot to learn more. You can view the full searchable map, and learn more about the data, using the link below.
