A complete list of all programs within the Department of Environment, Great Lakes, and Energy (EGLE)
Community involvement and public participation are an essential part of EGLE’s mission, vision, and values.
SARA Title III establishes requirements regarding emergency planning and "Community Right-to-Know" reporting on hazardous and toxic chemicals for federal, state, local, and tribal governments, as well as regulated facilities.
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.
The Michigan Department of Environment, Great Lakes, and Energy’s (EGLE) Water Well Viewer (WWV), is an interactive mapping system that displays water wells along with other information, such as wellhead protection areas, underground storage tanks, and sites of environmental contamination. Water well locations have been identified by address matching, the use of global positioning systems (GPS), and by legal descriptions.
This system allows water well drilling and pump installation contractors to submit water well records.
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.
Anyone wishing to formally serve legal documents upon the Department of Environment, Great Lakes, and Energy (EGLE), or its officers or employees, may do so by the following methods.

The Department of Environment, Great Lakes, and Energy (EGLE) is implementing the following interim strategy/requirements to guide Wastewater Treatment Plants (WWTPs) and landowners/farmers who make decisions on land applying biosolids with detectable concentrations of Perfluoroalkyl and Polyfluoroalkyl Substances (PFAS).
EGLE implemented the Land Application of Biosolids Containing PFAS Interim Strategy first in 2021, with subsequent modifications in 2022 and 2024. Requirements under the 2024 updated interim strategy are detailed below and apply to all facilities with approved Residuals Management Programs (RMPs) under Michigan’s Part 24 Biosolids Rules.
Continue source identification and reduction efforts
Prohibit land application of industrially-impacted biosolids
Mitigate (reduce) risks moving forward
Inform landowners, farmers, and WWTPs about PFAS; create and retain publicly available information
Two PFAS analytes, Perfluorooctanoic Acid (PFOA) and Perfluorooctane Sulfonate (PFOS), are regulated under the interim biosolids strategy and depending on the concentrations identified of either analyte, may trigger additional actions as identified below.
(Industrially impacted threshold)
Biosolids with a PFOS or PFOA concentration of 100 µg/kg or higher are deemed industrially impacted and cannot be land applied. Additional requirements are as follows:
Biosolids with a PFOS or PFOA concentration at or above 20 μg/kg, but below 100 μg/kg, are considered elevated under the updated strategy and trigger the following requirements:
Biosolids with PFOS and PFOA concentrations below 20 µg/kg may be land applied with no additional requirements after submittal of results via MiEnviro Portal and communication of results to the landowner/farmer.
Facilities who wish to obtain and/or maintain the Exceptional Quality designation for biosolids, must have a combined concentration of PFOS and PFOA below 20 µg/kg under the updated interim strategy. Compliance with this condition must be demonstrated via quarterly monitoring.
These requirements are in addition to, and do not supersede or replace, in any way, other requirements for Exceptional Quality designation as defined in the state and federal biosolids regulations.
All facilities that land apply Class A or Class B biosolids are required to collect one representative sample of the finished biosolids product per calendar year prior to land application.
All facilities with biosolids designated as Exceptional Quality (EQ) are required to collect representative samples of the finished biosolids product on a quarterly basis.
All samples must be submitted to EGLE via MiEnviro Portal at least two weeks prior to land application.
Facilities with approved Residuals Management Programs shall provide the PFOS and PFOA analytical results and additional information specific to PFAS and biosolids in Michigan via hard copy or electronic mail to the landowner and farmer (if different) prior to land application of biosolids.
Currently, there are no United States Environmental Quality Agency (USEPA)-approved methods for PFAS analysis of sludge and biosolids.
Analyses may be performed using EPA Method 1633, ASTM D7979, or an isotope dilution method (sometimes referred to as Method 537 modified) until one or more analytical methods are promulgated in Title 40 of the Code of Federal Regulations (40 CFR), Part 136, Guidelines Establishing Testing Procedures for the Analysis of Pollutants, at which time only promulgated methods may be used.
Until there is an approved method, all biosolids PFAS sample results shall at minimum include the 28 analytes previously used on the MPART PFAS minimum laboratory analyte list.
EGLE requires all facilities with approved Residuals Management Programs (RMPs) to sample once per calendar year prior to the initial land application of the year.
For some winter land applications, it can be difficult to complete sampling prior to land application when conducted within the first month of the year (January). If a facility with an approved RMP had a seasonal land application that was intended to be completed by the end of the year (December 31), this application could be completed through January 31 of the following year. If there is a possibility land application may be extended past January 31, facilities with approved RMPs are required to collect a new biosolids sample for PFAS analysis and submit the results prior to land application. Requests of land application extensions shall be submitted to the WRD via email.
Decisions regarding winter land application extensions will be based on past biosolids PFAS data, biosolids source effluent data, and any other relevant data.
The implementation of these updated measures is part of an interim strategy to mitigate risk to public health and the environment from potential adverse effects of biosolids containing PFAS. Notification of these requirements in the updated strategy was made via e-mail to facilities with existing approved Residuals Management Programs.
These additional requirements are considered a modification to the approved Residuals Management Program and are made in accordance with provisions outlined within Michigan’s Part 24 Administrative Rules, Land Application of Biosolids, promulgated pursuant to Part 31, Water Resources Protection, of the Natural Resources and environmental Protection Act, 1994 PA 451, as amended (NREPA), specifically Rule 2404(1), and language contained within existing discharge permits.
