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.

EGLE's report entitled "A Strategic Environmental Quality Monitoring Program for Michigan's Surface Waters" (Strategy) describes the monitoring activities that are necessary for a comprehensive assessment of water quality in Michigan's surface waters. One important component of the Strategy is sediment chemistry monitoring.
The sediment chemistry monitoring activities are consistent with existing EGLE programs. For example, EGLE uses the existing 5-year basin units defined by the NPDES permitting program, which includes 45 watershed units based on drainage to the four Great Lakes. Monitoring activities in each watershed include not only sediment chemistry, but also aquatic life community evaluations, fish and wildlife contaminant studies, and water chemistry. Integrating the sediment chemistry monitoring with the other activities, within the framework of the five-year permitting cycle, will ensure that the monitoring is closely linked with other EGLE programs and contributes to resource management decisions.
The specific objectives of sediment chemistry monitoring are to:
The sediment chemistry element consists of two components that, in combination, provide data necessary to achieve these objectives. These include:
For the inland lake trends component, several inland lakes will be assessed over several years. Through 2009, a total of 44 lakes have been monitored. Of these 44 lakes, 10 were sampled twice. Sediment samples are analyzed for total mercury, trace metals (cadmium, chromium, copper, lead, nickel, zinc), total PCBs, and organochlorine pesticides such as DDT. Inland lake trend data are summarized in annual trend reports produced by Dr. Dave T. Long of Michigan State University and reviewed and approved by the Water Resource Division's Great Lakes Watersheds Assessment, Restoration, and Management Section staff.
Sediment samples collected as part of the watershed surveys are analyzed for a variety of parameters, based on local conditions and known/suspected sources. Data collected as part of the 5-year watershed surveys are summarized in watershed reports and are entered into EPA's Water Quality database.
