The Land Restoration Program (LRP) of the Maryland Department of the Environment provides financial incentives for the redevelopment of brownfields, which are sites that either qualify for the Voluntary Cleanup Program or are contaminated by oil. Redevelopment of these sites will help revitalize industrial and commercial areas. LRP also administers the "Superfund" program for the State of Maryland that assesses suspected hazardous waste sites, including federal facilities, to control and remove environmental and public health threats through site cleanups and remedial actions. As a public service, LRP distributes their GIS data identifying these site locations in several different file formats. They include OGC Compliant Web Map Services, OGC Compliant Web Feature Services, ArcGIS Web Map Services, and Keyhole Markup Language (KML) format.
