The Michigan Department of Environment, Great Lakes, and Energy's (EGLE) Environmental Remediation Program manages and reduces risk at sites of environmental contamination. This is achieved through activities such as site evaluation, feasibility studies, operation and maintenance of systems, implementing land use and resource use restrictions, and monitoring. This data layer shows facilities that have been identified and mapped under Part 201, Environmental Remediation, of the Natural Resources and Environmental Protection Act, 1994 PA 451, as amended (NREPA) those areas, places, or parcels of property, or portion of a parcel of property where a hazardous substance in excess of the concentrations that satisfy the cleanup criteria for unrestricted residential use has been released, deposited, disposed of, or otherwise comes to be located. This data layer does not include all of the facilities that are subject to regulation under Part 201 because owners are not required to inform EGLE about the facilities and can pursue cleanup independently. Facilities that are not known to EGLE are not on the Inventory, nor are locations with releases that resulted in low environmental impact. This data is regularly updated.

Michigan’s environmental remediation program authorizes EGLE to set cleanup standards by considering how the contaminated land will be used in the future. Michigan’s cleanup standards are risk-based and reflect the potential for human health or ecological risks from exposure to hazardous or regulated substances at contaminated sites. A person may use land use or resource use restrictions, as outlined in Part 201 and Part 213, to manage risk by reducing or restricting exposure to environmental contamination left in-place at a property.Land or Resource Use Restrictions may be in various forms including Restrictive Covenant, Notice of Aesthetic Impact, Notice of Corrective Action, Local Public Highway Institutional Control, Michigan Department of Transportation (MDOT) Environmental License Agreement, Local Ordinance, or an Alternative Institutional Control.This dataset shows locations of Land or Resource Use Restrictions that have been used to aid in the closure of a site of environmental contamination. The locations provided are not all-inclusive as they only represent those restrictions that have been sent to EGLE. This polygon dataset must be used along with the available point dataset Land or Resource Use Restrictions (Points) to show all the EGLE-mapped restrictions. Restrictions having proper legal descriptions and/or surveyed restriction area are represented with a polygon, while those having incomplete area and/or location details are represented by a point feature. The data is refreshed from daily from EGLE’s spatial database engine.Restrictions are mapped relative to existing GIS datasets including survey sections and aerial imagery and therefore have inherent inaccuracies. Locations provide a general representation but should not be relied upon for site-specific planning or decision making.The dataset’s field names are described below.

This data is used in the EGLE District Boundaries and Office Locations web app. This data includes all of Michigan Department of Environment, Great Lakes, and Energy (EGLE)'s district boundaries. This layer was developed with guidance from EGLE's Facilities and Operations team.

Many businesses utilize underground storage tanks for products such as gasoline, diesel fuel, and other liquid chemicals. Environmental damages and safety risks can result from improper installation and maintenance as well as degradation of the tanks over time. The design, construction, installation and maintenance of underground storage tanks that store regulated substances are licensed under Part 211, Underground Storage Tank Regulations, of the Natural Resources and Environmental Protection Act, 1994 PA 451, as amended (NREPA) by the Michigan Department of Licensing and Regulatory Affairs (LARA). Those underground storage tanks that require corrective actions due to a release are regulated under Part 213, Leaking Underground Storage Tanks, of NREPA by the Michigan Department of Environment, Great Lakes, and Energy (EGLE). This data layer shows the locations of known underground storage tanks in Michigan including those that have a record of a release. This data is regularly updated.

Recent Changes:Attributes available in this layer have changed as part of EGLE’s transition from Environmental Mapper to RIDE Mapper. Additional information is provided such as the number of tanks at each location as well as the number of total releases and open releases. As a result, an additional step is required to display Part 211 sites as active or closed, or to display leaking underground storage tank sites as open or closed. A new definition query or filter will help you accomplish this. The table below shows the relationships between fields in the old feature class and new as well as the query that can be used to view Active/Closed Part 211 sites and Open/Closed Part 213 sites using the new data structure.
