Thresholds: Indiana has developed a State operating permit program that is enforceable by federal EPA and allows sources to limit their air emissions to below the Title V threshold levels. A Federally Enforceable State Operating Permit (FESOP) permit can provide more operational flexibility. Many sources seek a FESOP to limit their emissions and not be subject to the Title V program.

Differences in regions: Check to see if your area is in attainment or non-attainment with federal air quality standards, which can affect permitting decisions.
