    Conclusions and Recommended Action

The EPA's review of the material submitted indicates that the state has amended the air quality rules in accordance with the requirements of the Clean Air Act. Missouri has determined that fee adjustments are needed to offset the effect of declining revenues and to maintain the solvency of the Missouri Air Pollution Control Program. EPA proposes to approve the requested revisions to the Missouri SIP and Operating Permits Program.
