Approval and Promulgation of Implementation Plans and Operating Permits Program; State of Missouri

EPA is taking final action on Missouri's request to incorporate two new rules and three revised rules into the State Implementation Plan (SIP) and Part 70 Operating Permit program. All of the rules pertain to Missouri's air permits program. Because of the state's request for approval of portions of the rules, EPA is not taking final action on all of the state-adopted rules. We are approving revisions to the Construction Permits Required rule and conditionally approving portions of the Construction Permits Required rule, which reference the Construction Permits by Rule. We are approving the Construction Permit Exemptions rule, except for the livestock markets and livestock operations exemption. We are conditionally approving the Construction Permits By Rule except for the livestock markets and livestock operations exemption.
