62-522.300: General Provisions for Ground Water Permitting and Monitoring

NOTICE IS HEREBY GIVEN THAT on May 1, 2007, the Department of Environmental Protection has issued an order.

The order is for the Redox Tech LLC variance petition (OGC File No. 07-0202), received on February 5, 2007. The petition requested a variance from the zone of discharge (ZOD) prohibition for discharges through wells under subsection 62-522.300(3), F.A.C., for the use of ABC+ to cleanup sites contaminated with chlorinated ethenes, several chlorinated alkanes, and potentially chlorinated phenols, pesticides, biphenyls, and other related contaminants. Specifically, the variance requested a ZOD for total recoverable petroleum hydrocarbons (TRPH) and ethanol within a 50-foot radius from the point of discharge for a duration of 365 days. Notice of receipt of this petition was published in the F.A.W., on March 23, 2007. No public comment was received. The final order granted a variance from the ZOD prohibition because the petitioner demonstrated a substantial hardship, and that the purposes of the underlying statutes would be met with the conditions imposed by the Department. The conditions require that the use of this product must be through a Department-approved remedial action plan, or other Department-enforceable document, and that such approval shall not be solely by a delegated program; that the discharge must be through a Class V, Group 4 underground injection control well which meets all applicable requirements of Chapter 62-528, F.A.C.; that the extent of the ZOD for TRPH and ethanol shall be a 50-foot radius from the point of injection and the duration of the ZOD shall be one year; that the injection of ABC+ shall be at such a rate and volume that no undesirable migration occurs of the product, its by-products, or the contaminants already present in the aquifer; and that the Department-approved remedial action plan shall address appropriate ground water monitoring requirements associated with the use of ABC+ based on site-specific hydrogeology and conditions.
