## Abstract

The purpose of this revision to the Missouri State Implementation Plan (SIP) is to revise the Missouri Part D new source review (NSR) rules, update and add numerous definitions, revise the maximum allowable increase for particulate matter under the requirements for prevention of significant deterioration (PSD) of air quality, address emission statements under Title I of the Clean Air Act Amendments (CAAA), and generally enhance the SIP. The objective of this final rule is to approve into the Missouri SIP rules adopted by the state which meet the requirements of the Clean Air Act (CAA) as amended in 1990 with regard to NSR in areas that have not attained the national ambient air quality standard. This implementation plan revision was submitted by the state pursuant to Federal requirements for an approvable NSR SIP for Missouri.
