Summary

The Environmental Protection Agency (EPA) is proposing to approve revisions to the Iowa State Implementation Plan (SIP) to include recent changes to the Linn County Code of Ordinances. The revisions include updating definitions and references to the effective dates the Federal rules were approved into the State's SIP, revising methods and procedures for performance test/stack test and continuous monitoring systems, and updating the Linn County permits program. These revisions will not adversely impact air quality and will ensure consistency between the state and federally approved rules.
