The Antidegradation Implementation Procedure Workgroup was created to help revise the Missouri Antidegradation Implementation Procedure (AIP). The Missouri Clean Water Commission approved the most recent revision July 13, 2016, which EPA approved July 30, 2018. According to 40 CFR 131.12, this procedure is intended to satisfy a requirement for states to develop and adopt a statewide antidegradation policy and identify methods for implementing such policy.

With more than 10 years experience, Missouri’s Antidegradation processes are well-developed. The AIP has provided reasonable wastewater treatment technology determinations that have helped maintain the quality of waters of the State. Since the earliest days of Antidegradation Implementation review, engineers identified a number of areas in which the AIP is unclear, situations that were not addressed or elements that needed additional clarification. The goal of this current revision is to address many of these elements and incorporate ideas that improve and streamline the process, while maintaining the fundamental goal of antidegradation.
