This layer displays the counties where award-winning AML projects are located along with information about the projects. Since project locations are not always known exactly, or may be near private residences, exact locations are not provided. This layer was created using information from OSMRE's website and joining it to US county boundaries. Agencies responsible for the reclamation projects are listed when known; the quality of the data improves after 1998. When available, hyperlinks to project descriptions and videos are included as well, generally for projects within the last 10 years.

As described by ASTM: D7780-12: This feature class contains points that depict the location of coal preparation plants on a given Coal Mining Operation. This dataset consists of coalmining related features as described by ASTM D7780-12, "Standard Practice for Geospatial Data for Representing Coal Mining Features". These data are gathered using automated processes from participating coalmining regulatory authorities, which are generally state government agencies. The data from the various sources are transformed into common schemas as described by the ASTM Standard above. The resultant feature classes represent seamless information covering the coal producing areas of the United States. Development of these data are ongoing and will become more complete as more cooperating regulatory authorities are added to the GeoMine system.

As described by ASTM D7780-12: This feature class contains points that depict the location of environmental resource monitoring locations (ERMLs), including groundwater and surface water monitoring sites, NPDES locations, and certain types of sampling points.

As described by ASTM D7780-12: Designated by the Regulatory Authority for individual areas within permitted coal mining and reclamation operations. The bond status may be represented by Bonded, Not Bonded, Phase I Release, Phase II Release, Phase III Release, Forfeited or Termination of Jurisdiction (TOJ).

As described by ASTM D7780-12: This feature class contains polygons that depict the location of coal refuse disposal areas. They include, but are not limited to, slurry impoundments (including cross valley, diked, and incised impoundments), slurry cell structures, and coarse coal refuse structures.

Layer displaying the locations of EMS Regional Offices in Maryland.

This dataset contains coal cases derived from Legal Land Descriptions (LLD) contained in the US Bureau of Land Management's, BLM, Mineral and Land Record System(MLRS) and geocoded (mapped) using the Public Land Survey System (PLSS) derived from the most accurate survey data available through BLM Cadastral Survey workforce. Geospatial representations might be missing for some cases that can not be geocoded using the MLRS algorithm. This data set contains cases with the dispositions of 'Authorized', 'Pending','Closed', and 'Interim'.,
