Part 201 Environmental Contamination Sites

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. Field Name Alias Description OBJECTID N/A N/A SITENAME Site Name Name for the location assigned by RRD ADDRESS Address Street address for the site CITY City City associated with the street address ZIPCODE Zip Code Zip code the of the site COUNTY County County where the site is located LATITUDE Latitude Latitude (Y-Coordinate) of the site LONGITUDE Longitude Longitude (X-Coordinate) of the site SITEID Site ID Unique identifier for the site within RRD’s RIDE database which connects to the Environmental Mapper BusinessType Business Type General classification of the type of business that is/was associated with the Part 201 site. HorizontalReferenceDatum Horizontal Reference Datum Horizontal Reference Datum HorizontalCollectionMethod Horizontal reference Method of Collection Describes the method used for identifying the site HorizontalAccuracy Horizontal Accuracy (m) An estimated measure of the horizontal accuracy of the point in meters. ReferencePoint Reference Point Provides a description of the relationship between the point feature and the overall site SourceMapScale Source Map Scale The representative fraction or scale at which the point feature was mapped RiskCondition Risk Condition Risk condition classification applied to the site by EGLE's Remediation and Redevelopment Division, which is used by the division to identify sites that are a priority to address, to manage workloads, and to report metrics on the overall facility status consistently across programs. Contaminants Contaminants Chemical classification identified on the site HasBeaOrNom HasBeaOrNom Indicates whether EGLE has knowledge of a baseline environmental assessment or a notice of migration for the site.
