  • The Division of Environmental Response and Revitalization (DERR) is rescinding aspects of its guidance document titled, “Sample Collection and Evaluation of Vapor Intrusion to Indoor Air for Remedial Response and Voluntary Action Programs (May 2010).” DERR considers Chapter 10 (Data Evaluation) and Chapter 11 (Modeling the Vapor Intrusion Pathway) to be out of date and are no longer considered appropriate guidance for projects seeking cleanup under any of DERR’s programs. Until DERR has the opportunity to revise these chapters or issue new guidance, it is appropriate to rely on U.S. EPA’s guidance document titled, “Technical Guide for Assessing and Mitigating the Vapor Intrusion Pathway from Subsurface Vapor Sources to Indoor Air (June 2015)” and U.S. EPA’s Vapor Intrusion Screening Level (VISL) calculator.

***This updates and replaces an announcement previously posted on July 23, 2015.

  • This June, US EPA, Office of Solid Waste and Emergency Response (OSWER) issued final guidance for the evaluation of vapor intrusion to indoor air (US EPA VI guidance). The US EPA VI guidance, similar to DERR’s 2010 VI guidance, emphasizes a “multiple-lines of evidence” approach when evaluating the VI pathway. US EPA refers to the Vapor Intrusion Screening Level (VISL) Calculator as the preferred frontline screening methodology, and de-emphasizes reliance on mathematical models, the use of which is included in DERR’s 2010 VI guidance. This has led to some confusion on which tool to use to screen out the VI pathway or evaluate compliance with applicable standards for VAP.

    DERR has reviewed the new federal guidance for application when evaluating sites under our cleanup programs. For Remedial Response and RCRA sites, we are recommending use of the US EPA VI guidance for VI investigations, along with some aspects of the DERR’s 2010 VI guidance. For more specific information, please contact the appropriate program. Similarly, for VAP, we advise the use of the VISL Calculator for screening, with emphasis on further sampling (soil gas and indoor air) if site concentrations exceed screening levels. Mathematical modeling, which is permitted under the VAP rules, may have utility but should be evaluated on a site-specific basis. With respect to the Johnson and Ettinger model for vapor intrusion to indoor air specifically, the appropriateness of using this model has been called into question. However, no further action letters that include VI demonstrations may continue to rely on mathematical modeling conducted in accordance with the VAP rules and DERR’s 2010 VI guidance until such time the guidance is updated. We also strongly recommend you consult with the program if you have a project with VI issues, especially if you have or would like to rely upon VI modeling.

What We Do

The Division of Environmental Response and Revitalization (DERR) handles the investigation and cleanup of contaminated sites, including RCRA corrective action and closure, VAP, federal facilities, Superfund and remedial response. DERR provides emergency response and oversight of environmental emergencies, spills, incidents and releases, as well as emergency preparedness assistance. DERR also provides assistance and guidance to communities and private entities interested in assessment, clean up and reuse of brownfield sites.

Mission Statement

The Division of Environmental Response and Revitalization protects human health and improves the quality of the environment for present and future generations through the prevention, identification, investigation, regulation and remediation of chemical and petroleum hazards in all environmental media.

Long-Term Goals

  • Determine that sites are safe for their intended use.
  • Effectively and efficiently respond to the sudden releases of contaminants that may negatively impact Ohio's environment.
  • Achieve integration of DERR's cleanup programs with voluntary, involuntary and sudden release approaches.
  • Define and identify Ohio's contaminated sites that DERR will address.
  • Secure adequate infrastructure to effectively and efficiently administer Ohio's cleanup program. (Assumes response is a part of the integrated cleanup program.)
  • Administer an effective and efficient prevention program that results in fewer releases to Ohio's environment.
