Review and discussion of changes made in response to public comment from the previous rule workshop. Chapter 62-780, F.A.C. has not been substantially updated on a technical basis since adoption in 2005. In the intervening time, much has been learned with regard to applying Risk-Based Corrective Action (RBCA) principles to contaminated site management and closure. The department is reviewing and updating these rules given technical advancement since original rule adoption. In addition, a number of inconsistencies or incongruities have been uncovered within the rule chapter, and these will be corrected. Specific topics to be addressed include notice requirements for conditional closure, addressing additivity, evaluation of Incremental Sampling Methodology, and splitting the current rule 62-780.500 into two separate rules, one for emergency response actions and one for interim source removal. The agenda and draft rule will be available at http://www.dep.state.fl.us/waste/ by March 29th or by contacting the contact person listed below.
