Colorado Department of Public Health and Environment (CDPHE) published an update to their vapor intrusion (VI) guidance in May 2021 that applies to Colorado cleanup sites including Resource Conservation and Recovery Act (RCRA), voluntary cleanup program (VCP), dry cleaner, and Brownfield Program sites. The updated guidance document adopts many concepts from U.S. Environmental Protection Agency (EPA) and Interstate Technology and Regulatory Council (ITRC) guidance documents, including the adoption of EPA regional screening levels (RSLs) and vapor intrusion screening levels (VISLs), as well as petroleum site screening criteria. This presentation will provide an overview of the new guidance document, including a summary of noteworthy changes and updates, and a discussion of how the guidance may impact current Colorado VI sites.
