RIDE Mapper

RIDE Mapper is an online map application focused on sites related to the work of the Remediation and Redevelopment Division (RRD), including:
  • Sites of environmental contamination regulated under Part 201
  • Leaking underground storage tank sites (open and closed) regulated under Part 213
  • Federal Superfund and Formerly Used Defense Sites
  • Land or resource use restrictions that have been provided to EGLE
In addition to providing information about where these sites exist, RIDE mapper also helps with understanding of what resources and land uses exist around these locations. 
 
An updated version of RIDE Mapper launched on April 22, 2026, marking the two-year anniversary of the initial release of the map viewer. The updated RIDE Mapper provides access to more data layers and helps users find needed information more quickly through use of a reorganized data catalog. 
 
April 2026 RIDE Mapper Enhancements

Data layers added to RIDE Mapper include:

  • Water wells (Michigan Wellogic)
  • Waste management information
    • Hazardous waste sites under Part 111
    • Solid waste landfills under Part 115
  • Geologic information:
    • Quaternary features and geology
    • Bedrock geology, and
    • Glacial lobe boundaries (Michigan Background Soil Survey)
  • Formerly Used Defense Sites

Functional enhancements include:

  • Easier to find the data you need due to reorganized data layers
  • Primary environmental remediation data layers are visible at start-up
  • More prominent 'search by address' tool

Your map to RIDE

As the name indicates, RIDE Mapper has strong connections to the Remediation Information Data Exchange (RIDE) application. RIDE Mapper shows the locations of facilities regulated by RRD. Basic site information and attributes about facility locations are available in RIDE Mapper, but more detailed site information is available in RIDE. 

RIDE allows for the exchange of data and information related to contaminated properties. The regulated community can submit and view documents electronically in many cases. Certain hyperlinks in RIDE Mapper will take you directly to the pertinent information in RIDE. We'll strive to make these connections even stronger and more seamless in the future to provide both the detailed site information you need along with the ever-important location context.

Data disclaimer

Information provided through RIDE Mapper is based in part on submittals provided to EGLE by the owner/operator or their consultant. The information may not be reflective of actual site and tank data due to various reasons, such as failure to report changes, an error in reporting ownership changes, and data entry errors.
 
Mapped locations have been identified by address matching, the use of global positioning systems (GPS), and in some cases by drawing boundaries based on legal descriptions provided in documents submitted to EGLE. Mapped points and areas are intended to show a good representation of the feature relative to the aerial photograph, basemaps, and other reference layers; however, these features are not survey-grade and should not be used as such. See the metadata for each map layer to obtain additional data quality information and use limitations.
 
Some sites exist in the RIDE database, but they are missing latitude and longitude information, so these sites will not appear in RIDE Mapper. See the Inventory of Facilities in the RIDE Database for the complete list of sites know to EGLE.

EGLE does not make any representations regarding the accuracy of the information, nor does it accept any responsibility for errors or omissions contained therein.
