Ameren Sioux Sulfur Dioxide Consent AgreementState Implementation Plan (Sip) Revision • April 14th, 2022
The purpose of this State Implementation Plan (SIP) revision is to incorporate Consent Agreement No. APCP-2021-018 into Missouri’s SIP. This Consent Agreement is between the Missouri Department of Natural Resources’ Air Pollution Control Program (Air Program) and the Ameren Missouri (Ameren) – Sioux Energy Center (Sioux). The Consent Agreement establishes an enforceable mechanism for new sulfur dioxide (SO2) emission limits at Sioux. This will allow the Air Program to rely on these new lower limits in future SIP actions and other technical demonstrations required under the Clean Air Act (CAA).
