Annual Compliance Certifications

In Indiana, regulated entities with Part 70 (Title 5) or federally enforceable state operating permits (FESOP) issued by IDEM’s Office of Air Quality (OAQ) are required to certify compliance through the submittal of Annual Compliance Certifications (ACC).

ACC submittal dates:

  • FESOP and Part 70 (Title 5) - for Clark, Elkhart, Floyd, Lake, Marion, Porter, St. Joseph, and Vanderburgh Counties, the ACC - due no later than April 15
  • FESOP and Part 70 (Title 5) - for all other counties - due no later than July 1

Much of the required information for the ACC comes from the permitted source’s quarterly deviation and compliance monitoring reports, permit conditions, inspection reports, and internal review practices. OAQ’s air inspectors are required to review all of the 1,100 plus certifications that are received or should have been received, and they must request resubmittals if errors are found within the reports.
