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 system-wide SO2 emission cap for AEP plants that becomes increasingly stringent through 2029. The modification also gives us more flexibility in how we meet these requirements.
