## Abstract

EPA is approving a State Implementation Plan (SIP) revision submitted by the state of Missouri for the inclusion of revisions to the Construction Permit Exemptions rule. The Construction Permit Exemptions rule lists specific construction or modification projects that are not required to obtain permits under the Construction Permits Required rule. Revisions to this rule include updating the insignificance levels, adding a new exemption for manufacturing operations (which produce insignificant emissions), clarifying the grain handling facilities exemption, and restructuring of the record keeping portion of the rule. Missouri developed the revisions to this rule under two separate state rulemaking processes.
