RCRA Permitting Risk Assessment

EPA’s hazardous waste permitting program established by RCRA helps ensure the safe treatment, storage, and disposal of hazardous wastes by establishing specific requirements that must be followed when managing hazardous wastes. Human health is an integral part of risk based closure of permitted units, developing groundwater remediation goals or permit limits, and for evaluating operating permits, including permit issuance, annual monitoring and closure, for 40 CFR 264 Subparts O (incinerators) and X (miscellaneous units) facilities and for 40 CFR 266 Subpart H facilities (boilers and industrial furnaces).

DEQ has developed a new tool using the latest EPA Risk Screen Level (RSL) data called Virginia Unified Risk Assessment Model (VURAM). VURAM does not include fate and transport based modeling for soil-to-groundwater transfer. Please include all the results of the screening level risk assessment as well as the VURAM report (output) in its entirety. Refer to the VURAM User Guide for instruction on how to install and use VURAM. The latest version of VURAM supersedes all previous versions. It is the facility’s responsibility to ensure that the most current version of VURAM is used in risk assessments regardless of whether the DEQ’s web-based risk assessment guidance pages have been updated.

For More Information

Please contact DEQ Risk Assessment staff or more information regarding fate and transport modeling or VURAM Risk Assessment please.
