The department submitted that original SIP-Interstate Transport Provisions for the 2015 Ozone Standard revision in June 2019. This supplement includes updated analyses based on the latest national modeling results. The revision also includes new Consent Agreements to help control emissions at three facilities in Missouri. The original SIP submittal and this supplement demonstrate that Missouri’s SIP contains sufficient provisions to ensure emissions in Missouri are not significantly contributing to nonattainment or maintenance problems in any downwind state with respect to the 2015 ozone standard.
