Petroleum Vapor Intrusion – Updates to the Lateral Inclusion Zone Checklist and Vertical Separation Distance Checklist

2023-02-23T17:00:00Z 2023-02-23T18:00:00Z Petroleum Vapor Intrusion – Updates to the Lateral Inclusion Zone Checklist and Vertical Separation Distance Checklist

Petroleum vapor intrusion (PVI) is the process by which hydrocarbons volatilize from petroleum-contaminated soils, groundwater, and light nonaqueous phase liquids and migrate through the vadose zone. EGLE has determined the Interstate Technology & Regulatory Council (ITRC) PVI guidance document (https://projects.itrcweb.org/PetroleumVI-Guidance) provides a suitable process for a petroleum vapor intrusion assessment for the volatilization to indoor air pathway (VIAP) pursuant to relevant statutory provisions. To assist in the use of the site screening process using soil and groundwater data, the department has developed a Precluding Factors Assessment for the ITRC Lateral Inclusion Zone Checklist and a Precluding Factors Assessment for ITRC PVI Separation Distances Checklist. EGLE Remediation and Redevelopment (RRD) staff will use these checklists when reviewing submittals that propose to rely on the ITRC PVI lateral and/or vertical separation distances. Join EGLE to hear updates to the PVI checklist and the application at sites with petroleum releases.

After registering, you will receive an email from "EGLE Outreach" with a link for you to use to join the webinar.

Individuals needing language assistance or accommodations for effective participation should contact Joel Roseberry roseberryj@michigan.gov by February 3 to request language, mobility, visual, hearing, translation, and/or other assistance.
