Environmental Mapper

The Environmental Mapper is an online application that allows users to view sites of environmental contamination under Part 201, leaking underground storage tank sites (both active and closed) regulated under Part 213, and underground storage tank facilities (both open and closed) regulated under Part 211.

In addition, users can view any land use or resource use restrictions imposed on a property that has been provided to EGLE. Users can search and display sites based on city, county, EGLE district, and/or Michigan legislative districts. Internal map functions allow the user to view and search for sites within a certain distance, lot of land, or stream segments.

Data disclaimer

The information is based in part on forms provided to the Michigan Department of Environment, Great Lakes, and Energy (EGLE) by the owner and/or his/her consultant. The information may not be reflective of actual site and tank data due to various reasons, such as the owner's failure to report changes, an error in reporting ownership changes, and data entry errors.  The locations on the maps have been identified by address matching and the use of global positioning system (GPS) instruments. There are a few sites for which the latitude and longitude information is missing and so the sites will not appear in the "Michigan Environmental Mapper." For the complete list of sites, known to EGLE, see the following links:
