Screening Level Ecological Risk Assessment Protocol for Hazardous Waste
Combustion Facilities
**Peer Review Draft**
**Peer Review Draft**
Risk assessment is a science used to evaluate the potential hazards to the environment that are attributable to emissions from hazardous waste combustion units. There is guidance available regarding the general ecological risk assessment process including problem formulation, analysis, and risk characterization (U.S. EPA 1997c; 1998d). This document expands on that general guidance with respect to the ecological screening level procedures and provides a prescriptive tool to support permitting of hazardous waste burning combustion facilities under the Resource Conservation and Recovery Act (RCRA). It is not intended to be used to perform screening or baseline ecological risk assessments (ERA) in other areas of the RCRA program, such as corrective action.
This document is organized into six chapters and eight appendices contained in three volumes as follows:
Volume 1: Screening Level Ecological Risk Assessment Protocol for hazardous Waste Combustion Facilities
Volume 2: Appendix A: Chemical-specific Data
Volume 3: Appendices B to H
