Do I need to submit a FOIA?
Maybe not. The Department of Environmental Quality (DEQ) provides online access to several databases that may contain the information you need:

DEQ Site Registry - The DEQ Site Registry is a geographically-based database that presents information about facilities and locations of interest to the Michigan Department of Environmental Quality (MDEQ) and the environmental community.  This site contains general site information on active and closed facilities and the environmental interests at the site.  Facilities and compliance data from additional MDEQ databases will be added as resources become available.  It can be utilized to determine if more than one division/program has an environmental interest in a particular facility.  Links to GIS (Michigan's Center for Geographic Information) allows facilities to be geographically searched and mapped.

The database currently contains site information from Toxic Release Inventory (TRI) - OEA, NMS - Water Resources Division (WRD), Emission Reporting - Air Quality, WDS - Resource Management Division (RMD), Complaints Database - (WRD), and MIR - Office of Oil, Gas and Minerals, and compliance information from RMD, Complaints Database, MIR, and NMS.

Will I be charged for information requested under FOIA?
A public body may charge a fee for the necessary copying of a public record for inspection or providing a copy of a public record to a requester. A public body may also charge for search, examination, and review and the separation of exempt from nonexempt information in those instances where failure to charge a fee would result in unreasonably high costs to the public body. If you need an estimate of the cost of fulfilling your request BEFORE we take action to fill it, please indicate that in your request.


How long will it take to receive information requested under FOIA?
After receiving a request for a public record, a public body has five (5) business days to respond.  The public body may also extend the time by 10 business days by notifying the requestor in writing thereby making the due date 15 business days from the date of receipt of the request.


Air Quality Division information:

Please note that FOIA requests for Southeast Michigan (SEMI) District Wayne County sources/sites, Air Quality Division files are located in the DEQ Detroit Office located at Cadillac Place, 3058 W. Grand Boulevard, Suite 2-300, Detroit, Michigan. If a file review is requested/required for Wayne County sources/sites, a separate trip to the Detroit Office may be needed to complete your review. The FOIA liaison for the Air Quality Division, SEMI District, splits her time between both the Warren and Detroit Offices and appointments are available when she is in the office. Please keep this in mind when you are planning your timeline for your project deadline.

Waiver of Fee:
The FOIA Coordinator will issue a fee waiver for the first $20.00 of the fee for each request to an individual who submits an affidavit stating that the individual is receiving public assistance or stating facts showing inability to pay the cost because of indigence.
