The Michigan Department of Environment, Great Lakes, and Energy (EGLE) is excited to present the Remediation and Risk Management Webinar Series [ [link removed] ]. This webinar series is dedicated to helping environmental professionals stay informed about issues and trends that affect remediation and risk management efforts. EGLE will regularly host a webinar that will tackle a topic of interest to environmental professionals and others interested in environmental remediation and risk management.

Each webinar will include a presentation by a diverse selection of environmental professionals and allow time for questions from attendees. Recordings of each webinar will be available on the Series webpage [ [link removed] ]. More webinars will be added throughout the year. Registration is available at Michigan.gov/EGLEevents [ [link removed] ].

Upcoming webinar in the series

September 3, 1 - 2:30 PM 
Volume 4 – Investigative Approach for Petroleum Volatilization to the Indoor Air Pathway (VIAP) Training [ [link removed] ]

Volume 4 – Investigative Approach for Petroleum Volatilization to the Indoor Air Pathway (VIAP) [ [link removed] ] has been finalized and released on July 26, 2024, by the Department of Environment, Great lakes, and Energy (EGLE), Remediation and Redevelopment Division (RRD). RRD staff will provide a document overview and training on the document on September 3rd at 1 p.m.

The Investigative Approach for Petroleum VIAP is one of seven volumes that will make up a Guidebook that will eventually update and replace the May 2013 EGLE Guidance Document for the Vapor Intrusion Pathway. The Investigative Approach for Petroleum VIAP is a concise process for the evaluation and screening process at petroleum release sites. Attachments are included to provide more information and details when needed based on site conditions.

Some highlights of this document include:


* Identifies the 3 site conditions where risks from petroleum vapor intrusion have the greatest potential:
* NAPL entering or being close to a structure.
* Contaminated groundwater entering a structure.
* Mobile NAPL entering utilities.

* Clarifies the use and where to begin the measurement of the lateral inclusion zone – EGLE RRD will be using NAPL and contaminated groundwater, not soil above screening levels absent of NAPL.
* Discusses the use of soil gas data for showing compliance with criteria/screening levels and risk evaluation.
* Outlines the data needs for when a property/structure screens in and needs evaluation.
* Identifies and discusses the need to evaluate conduits when a petroleum vapor source has entered into it.

This new guidance has been released as an electronic resource on RRD’s Vapor Intrusion webpage [ [link removed] ] with the ability to download a hard copy [ [link removed] ]. This webpage was developed to promote a clear and concise way to provide a consistent and informed approach for EGLE for the volatilization to the indoor air pathway using most up to date science.

*Speakers: *Matthew Williams, Volatilization to Indoor Air Specialist; Shane Morrison, Volatilization to Indoor Air Toxicology & Risk Assessment Specialist; Nick Swiger, Technical Support Unit Manager
