Section 502(b)(10) Change Notification Instructions

The Department recommends that the permittee contact the Division of Air Resource Management (DARM) to discuss any prospective 502(b)(10) change prior to submitting a change notification. If the Department subsequently determines that a change does not qualify as a 502(b)(10) change, and the permittee has already made the change, the facility may be subject to enforcement for having failed to obtain a required AC permit or Title V permit revision. Pursuant to Rule 62-213.410, F.A.C., the permittee may submit an applicability determination requesting that DARM verify that the proposed change qualifies as a 502(b)(10) change. The permit shield does not extend to 502(b)(10) changes, and the permittee must certify compliance with the existing permit terms on its annual compliance certification. If the 502(b)(10) change is to incorporate one or more engines, the Department recommends that the permittee complete and include with its submission the Engine Information Worksheet.
