Minor Source Change Notification Worksheet

On July 19, 2026, the Department revised Rule 62-210.300, F.A.C., to address changes made at permitted sources operating under a minor Air Operation Permit that contravene an express permit term or condition if the changes are not physical changes in, or changes in the method of operation of, the facility which increase the amount of any air pollutant emitted by the facility or which result in the emission of any air pollutant not previously emitted by the facility, and the changes do not exceed allowable emission under the permit (whether expressed as a rate of emissions or in terms of total emissions), as defined in Rule 62-210.200, F.A.C., if the source provides the Department with written notice at least 7 days prior to implementing any such operating change.

The Department recommends that the permittee contact DARM to discuss any prospective minor air operation permit change prior to submitting a change notification.  If the Department subsequently determines that a change does not qualify as a minor air operation permit 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 AO permit revision.
