Resources and information on utilizing RRD's data exchange and the Inventory of Facilities.
An interactive map displaying contaminated sites throughout Michigan regulated under Parts 213, 201, and 211.
EGLE's interactive calendar is designed to provide timely information on decisions before the Director, proposed settlements of contested cases, administrative rules promulgation, public hearings, meetings and comment deadlines, and environmental conferences, workshops and training programs.
The Michigan Freedom of Information Act (FOIA) provides all persons (except persons incarcerated in correctional facilities) with access to public records of public bodies. Requests to inspect or receive public records from EGLE must be in writing and describe the requested records with enough detail to enable the department to identify and locate the requested records. Some records are exempt from disclosure under the FOIA or another statute and thus will not be provided. A fee may be charged to process your request. Please note that many records are available that do not require a formal FOIA request.

Petroleum vapor intrusion (PVI) is a unique subdivision of the volatilization to the indoor air pathway (VIAP) distinguished by the influence of aerobic biodegradation in degrading volatile petroleum hydrocarbon (PHC) vapors over short distances. As a result, unacceptable risks from PVI are generally only observed where: 1) non-aqueous phase liquid (NAPL) is near or entering a structure; 2) NAPL has entered a utility that is connected to a structure; or 3) groundwater above the volatilization to indoor air criteria (VIAC) is entering a structure.
The risk evaluation associated with PVI should focus on contaminated groundwater at the surface (i.e., top) of the zone of saturation and areas where the NAPL body is located above the saturation zone or where mobile NAPL intersects and may enter an underground conduit that can transport vapors to a structure. For PVI, risk evaluation can often be carried out through application of nationally supported separation distances and/or strategic collection of representative soil gas samples above and around the NAPL body and contaminated groundwater.
