The Environmental Protection Agency (EPA) is proposing to approve a revision to Oklahoma’s State Implementation Plan (SIP). This update specifically addresses the regional haze program for the first implementation period.

Why it matters: This is a routine administrative step in the federal approval process for state air quality plans. It does not create new regulations or impose new burdens on the public; rather, it formalizes changes to the compliance requirements for a single power plant. The practical impact is limited to ensuring the state’s plan aligns with federal visibility protection standards.

Who it affects

  • Operators of the AEP/PSO Northeastern Power Station in Oklahoma
