Extension on FESOP and MSOP Permit Terms

The Indiana Department of Environmental Management (IDEM) is finalizing a rulemaking which will extend the permit term for Federally Enforceable State Operating Permit (FESOP) renewals and Minor Source Operating Permit (MSOP) renewals from 5 years to 10 years. The permit term for initial MSOPs and FESOPs will remain the same.

You can choose to implement this change only if you are on your second or subsequent renewal. This will be processed by the IDEM as either an Administrative Amendment (AA) for FESOPs, or as a Notice Only Change (NOC) for MSOPs. This basically means that the process for changing is relatively simple and no public notice period is necessary. Please contact DECA. We will be glad to help you apply for this change to your permit.
