The Department revised three rules under Chapter 62-210, F.A.C. (“Stationary Sources – General Requirements”): 62-210.200 (“Definitions”); 62-210.300 (“Permits Required”); and 62-210.370 (“Emissions Computation and Reporting”). The revisions include the creation of a new definition for an emissions-based source category (“Synthetic Minor – 80 Source (SM-80)”) for minor source facilities with a potential to emit equal to or greater than 80 percent of major source thresholds; authorization for facilities operating under minor source air operation permits a permit change procedure analogous to the off-permit change procedure that the Department recently codified for major sources in Rule 62-213.410, F.A.C.; clarify, consistent with United States Environmental Protection Agency (EPA) policy, that emissions unit reclassification of previously shut down emissions units shall not trigger prevention of significant deterioration (PSD) review unless the reactivation constitutes a major modification; specify that annual operating reporting requirements apply to SM-80 sources; and make other corrective and clarifying amendments. 

The Department filed the rule certification package with the Department of State and the rules became effective on July 19, 2026.
