The Department is revising subsection 62-621.300(4), F.A.C., the existing Stormwater NPDES Construction Generic Permit (CGP) to be consistent with the United States Environmental Protection Agency's rule revisions adopted 2012. The Department is also revising subsection 62-621.300(2), F.A.C., the existing Industrial Wastewater NPDES Generic Permit for the Discharge of Ground Water from Dewatering Operations (dewatering). The rule is being revised to eliminate permitting duplication for sites covered under the CGP that also have dewatering operations which will no longer need separate coverage under the industrial wastewater generic permits. Further, the revised dewatering generic permit is expected to reduce monitoring costs by approximately $950.00 on the first year of coverage alone, per facility, by eliminating initial screening and replacing effluent monitoring with site specific control measures (Best Management Practices). The new sediment control measures are more effective at minimizing or eliminating pollutant discharges from dewatering operations to surface waters of the State.
