Abstract
The Environmental Protection Agency (EPA) is taking final action to approve a revision to the State Implementation Plan (SIP) for the State of Missouri. This final action will amend the SIP to incorporate an additional sulfur dioxide (SO<INF>2</INF>) emissions limit for the Ameren Missouri (Ameren)--Sioux Energy Center (Sioux). Specifically, the EPA is approving into the SIP an additional SO<INF>2</INF> emissions limit and associated operating restrictions, monitoring, recordkeeping, and reporting (referred to as "MRR"), and testing compliance requirements established in a consent agreement as permanent and enforceable SO<INF>2</INF> control measures.
