New Source Review

In 2007, AEP signed a court-approved settlement of New Source Review (NSR) litigation. In 2013, a modification to the decree was approved by the U.S. District Court for the Southern District of Ohio, Eastern Division. The modification lowered a systemwide SO2 emission cap for AEP plants that becomes increasingly stringent through 2029.

We report annually on our compliance with the consent decree requirements. Below is an archive of our NSR Annual Reports:
