In 2009, the 2020 Corrective Action Baseline was introduced. The list of 3,746 facilities is where EPA and authorized states focused their attention to achieve EPA’s aspirational goal of 95 percent complete by the year 2020.
Periodically, the list has been updated for maintenance and quality control. In 2010, the 2020 Baseline was updated to include 3,747 facilities and in 2013, the 2020 Baseline was updated to include 3,779 facilities.
The documents below contain lists of the facilities that were both added to and removed from the 2020 Baseline in 2010 and 2013:You may need a PDF reader to view some of the files on this page. See EPA’s About PDF page to learn more.
