The Technical Branch houses all functions related to the regulation and monitoring of sites and facilities currently engaged in hazardous waste management. Typically this Branch is involved in Permitting, Corrective Action at active facilities, Remedial Action at closed or abandoned facilities, and risk assessment and management.

Risk Assessment

• Human Health
  • Human Health Risk Assessment Protocol (HHRAP) for Hazardous Waste Combustion Facilities - Final (September 2005). This document primarily focuses on the procedures used to estimate risk resulting from indirect pathways in relation to hazardous waste combustion facilities, but also describes the evaluation of direct inhalation risk. The document updates and replaces the 1998 Peer Review Draft version of the HHRAP (EPA530-D-98-001).

  • Screening Level Ecological Risk Assessment Protocol for Hazardous Waste Combustion Facilities Peer Review Draft (November 1999). This document expands on the general guidance regarding the ecological risk assessment process 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).

  • Risk Burn Guidance for Hazardous Waste Combustion Facilities (July 2001) This document contains EPA's recommendations regarding stack emissions tests which may be performed at hazardous waste combustion facilities for the purpose of supporting multi-pathway, site-specific risk assessments, where such a risk assessment has been determined to be necessary by the permit authority. The guidance recommends combustor operating and feed conditions that should generally be demonstrated during the testing, and identifies stack sampling and analytical techniques for collection of the emissions data. In addition, the relationship between test conditions and potential RCRA permit conditions is discussed.
