The purpose of this workshop is to discuss proposed amendments to the rules governing the Risk-Based Corrective Action (RBCA) process at contaminated sites in Florida. These proposed amendments were drafted in response to a Petition to Initiate Rulemaking on Chapters 62-780 and 62-777, F.A.C., filed by Associated Industries of Florida (AIF) pursuant to Section 120.54(7), F.S. The proposed revisions to Chapter 62-780, F.A.C., clarify that the “Referenced Guidelines” are guidance and not enforceable, add a hierarchy of information sources for reference when developing alternative cleanup target levels, specify the information needed when performing a probabilistic risk assessment and establish criteria for supporting a Site Rehabilitation Completion Order based on alternative cleanup target levels, but without institutional or engineering controls. Copies of the AIF Petition and the proposed draft rule language are available at www.dep.state.fl.us/waste/
