Description: 

The Environmental Protection Agency (EPA) is proposing approval of source-specific revisions to the Missouri State Implementation Plan (SIP) received on April 21, 2022. In the submission, Missouri requests that the EPA incorporate into the SIP an additional sulfur dioxide (SO<INF>2</INF>) emissions limit for the Ameren Missouri (Ameren)--Sioux Energy Center (Sioux). Specifically, the EPA is proposing to approve, into the SIP, an additional SO<INF>2</INF> emissions limit and associated operating restrictions, monitoring, recordkeeping, reporting (MRR) and testing compliance requirements established in a consent agreement as permanent and enforceable SO<INF>2</INF> control measures.
