Operating Permits

The Operating Permits Section was established to deal with the issuance of permits to operate facilities pursuant to Title V of the Federal Clean Air Act. Operating permits are designed to ensure equipment continues to perform as designed, to protect ambient air quality. Iowa's Operating Permit Program includes two types of operating permits: Title V and Small Source. Please read the Operating Permits - General Guidance " Frequently Asked Questions" document under Title V Technical Guidance for a more detailed discussion of the eligibility requirements for each type of permit.
