Risk Assessment: References & Scenarios



The following scenarios are provided solely as references to assist risk assessors in developing alternative risk-based exposure scenarios for the development of alternative cleanup target levels. This list is provided for informational use only and inclusion of a scenario here does not imply that DEP has ‘approved’ these scenarios for use in all cases. The use of a particular set of exposure assumptions, even when based upon one of these scenarios, must always be justified for use at a particular site. Similarly, risk assessors are always free to propose alternative parameters or parameter values to those used in the scenarios listed and to present different alternative scenarios as site conditions warrant. These scenarios are not part of chapter 62-780, F.A.C., cannot be enforced and in no way limit or constrain the proposal or use of other scenarios. Note also that use of an alternative scenario for risk-based closure of a site may also require the use of institutional or engineering controls.
