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.

In early 2018, EGLE’s Water Resources Division (WRD) developed the Industrial Pretreatment Program (IPP) PFAS Initiative Study of 95 municipal Wastewater Treatment Plants (WWTPs) to help identify and systematically reduce and eliminate sources of PFAS (PFOS/PFOA) entering wastewater collection systems. During this study, some WWTPs were found to have elevated PFAS in their effluent and associated residuals (sludge/biosolids). Through this study, WRD identified 6 WWTPs with industrially impacted biosolids. WRD temporarily restricted their land application program until elevated sources of the PFOS were eliminated and residual PFOS concentrations were decreased.
Expanding upon the information collected during the IPP PFAS Initiative, in the fall of 2018, WRD launched a study to evaluate the presence of PFAS in Municipal Wastewater and Associated Residuals. Through this study, 42 municipal WWTPs were sampled to evaluate the presence of PFAS in influent, effluent, and residuals. As part of this initiative, 29 land application sites (associated with 10 municipal WWTPs) were evaluated to further understand the potential impact land-applied biosolids has on the environment. AECOM Technical Services, Inc. (a consulting firm) was contracted by WRD to perform all the sampling in this study. All samples were analyzed for 24 PFAS compounds.
For a summary of the study and initial findings of the IPP PFAS Initiative, see the Summary Report: PFAS in Municipal Wastewater and Associated Residuals (Sludge/Biosolids). For the complete detailed report covering the IPP PFAS Initiative and the Statewide Study of 42 municipal WWTPs, see Evaluation of PFAS in Influent, Effluent, and Residuals of Wastewater Treatment Plants (WWTPs) in Michigan.

Interim Strategy – Land Application of Biosolids Containing PFAS
EGLE is implementing the following interim strategy/requirements to guide WWTPs and landowners/farmers who make decisions on land applying biosolids with detectable concentrations of PFAS. The following documents describe this strategy and requirements:
