Do I need to submit a FOIA?
Maybe not. The DEQ provides access to many databases that may contain the information you need, which can be found below.

DEQ Site Registry - The DEQ Site Registry is a geographically-based database that presents information about facilities and locations of interest to the DEQ and the environmental community. This page contains general information on active and closed facilities and the environmental interests at the site. Facilities and compliance data from additional DEQ databases will be added as resources become available. It can be used 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); NMS - Water Resources Division (WRD); Emission Reporting - Air Quality Division; WDS - Waste Management and Radiological Protection Division (WMRPD); Complaints Database - WRD; MIR - Oil, Gas, and Minerals Division; and compliance information can be found in WDS, Complaints Database, MIR, and NMS.

MiWaters is now open to the public. Site Explorer is a tool on the MiWaters Web site that allows you access to WRD information, including forms and documents. You are not required to sign up for an account to take advantage of this service.

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, 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.

DEQ FOIA standard cost

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

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.
