Air Plan Approval; Wyoming; Revisions to Regional Haze State Implementation Plan
type: GovernmentService
description: The Environmental Protection Agency (EPA) is approving a State Implementation Plan (SIP) revision submitted by the State of Wyoming on December 30, 2022, and supplemented on August 31, 2023, and November 16, 2023, addressing regional haze for Jim Bridger Units 1 and 2 (Wyoming 2022 SIP revision). Wyoming's 2022 SIP revision provides oxides of nitrogen (NOX) emission and heat input limits that collectively allow for identical reasonable progress as part of the long term strategy during the first implementation period as the associated emission limits in the existing SIP for Jim Bridger Units 1 and 2. The EPA is also approving monthly and annual NOX and sulfur dioxide (SO2) emission limits for Jim Bridger Units 1 through 4 that were included in Wyoming's 2022 SIP revision. The EPA is taking this action pursuant to the Clean Air Act (CAA or the Act).
