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.

The Michigan departments of Health and Human Services (MDHHS) and Environment, Great Lakes, and Energy (EGLE) and local officials are working together to protect residents in Monroe, Oakland, Livingston, Wayne, and Washtenaw counties following a release of hexavalent chromium to the Wixom Sewage Treatment Facility from Tribar Manufacturing in Wixom. The sewer feeds the Wixom wastewater treatment plant, which discharges to the Huron River system.
EGLE was notified at 3:21 p.m. August 1 by Tribar that it had released several thousand gallons of a liquid containing 5% hexavalent chromium into the sewer system. The company says it discovered the release Monday but indicated it may have started as early as Saturday morning according to Wixom city officials.
Testing of the Huron River has been ongoing and of more than 145 water samples collected throughout 42 river miles since the release, three came back with detections of hexavalent chromium – two detections in Milford’s Hubbell Pond and one in the middle of Kent Lake. The Kent Lake detection, completed by lab analysis – was 5 parts per billion (ppb) – just at the detectable limit of 5 ppb. The two Hubbell Pond detections were 11 and 9 parts per billion. All three were at or below values to protect aquatic life.

Hexavalent chromium is a form of the metallic element chromium. Chromium is a naturally occurring element found in rocks, animals, plants, soil, and volcanic dust and gases. It is used in many industries, including electroplating, welding, and chromate painting.
Hexavalent chromium, also referred to as hexchrome, is a known carcinogen that can cause a number of adverse health effects through ingestion, skin contact or inhalation.
