This practice addresses boundary data pertaining to areas that have been petitioned to be designated as unsuitable for mining relative to Title V Section 522 of the SMCRA as well as those lands that have been found by the RA’s process to be designated unsuitable for all or certain types of mining. These areas may be petitioned to be unsuitable for CMOs because of a number of reasons including but not limited to being fragile, historic, cultural, and scientific, having esthetic values, and having natural systems such as aquifers that a CMO could result in significant damage. This practice is significant as it provides for uniformity of geospatial data pertaining to the geographic location and description of both land petitioned and those areas ultimately ruled upon and designated with restrictions to CMOs.The lands unsuitable for mining petition geospatial data shall be obtained from RAs for CMOs. The coal mining community encompasses all entities directly and indirectly affected by CMOs including industry, and other interested parties, the public and the government at all levels within the United States.Within its area of exclusive jurisdiction, each RA is the ADS for coal mining spatial data that it creates and uses to regulate mining activity.This geospatial data standard will help ensure uniformity of data contributed by each RA and assist organizations in efforts to create, utilize, and share geospatial data relative to SMCRA, and it will lead to better communication between state, tribal, and federal regulatory offices, the public, and industry.Use of this standard over time will allow identification of changes in the boundaries of petition and designated areas.This standard conforms to the definition of a Data Content Standard as promulgated by the U.S. Federal Geographic Data Committee (FGDC). Terminology and definitions for identifying geographical features and describing the data model have been adopted from the FGDC Spatial Data Transfer Standard (See ANSI INCITS 320-1998 (R2003) and Project 1574-D).1.1 This practice describes minimum geospatial data required to locate and describe lands unsuitable for mining petitions (LUMP) and designated areas as a result of the petition.1.1.1 This practice addresses petition areas and any resulting designated areas geospatial boundary data as detailed in the Surface Mining Control and Reclamation Act of 1977 (SMCRA). This geospatial data shall be obtained from each state, tribal, or federal coal mining Regulatory Authority (RA), or combinations thereof, authorized under SMCRA to regulate coal mining operations (CMOs). Each RA shall be the authoritative data source (ADS) for this coal mining geospatial data.1.1.2 As used in this practice, a LUMP area was petitioned to be designated as unsuitable for CMOs. The RA is responsible for keeping a record of these areas as set forth in Title V Section 522 of the SMCRA and within the OSM regulations (30 CFR Part 761).1.1.3 This practice is one of several that have been approved or are in development related to SMCRA approved coal mining operations. Also under development is a terminology standard. Initial development of these standards is being done on an individual basis; however, they may be consolidated to reduce repetition of information between them.1.2 This practice applies to pre-SMCRA and post-SMCRA petition areas considered by the RA.1.3 This practice offers a set of instructions for performing one or more specific operations. This document cannot replace education or experience and should be used in conjunction with professional judgment. Not all aspects of this practice may be applicable in all circumstances. This ASTM standard is not intended to represent or replace the standard of care by which the adequacy of a given professional service must be judged, nor should this document be applied without consideration of a project’s many unique aspects. The word “Standard” in the title of this document means only that the document has been approved through the ASTM consensus process.1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

This practice is significant to the coal mining community because it provides uniformity of geospatial data pertaining to environmental resource location points throughout the United States. This standard is one of several coal mining geospatial data standards to be developed for use by an RA. These standards will help ensure uniformity of coal mining geospatial data used in internal business practices, exchanged among business partners within the coal mining community, and contributed by each ADS in future efforts to create national datasets describing coal mining in the United States. Use of this standard will result in organized and accessible data to support programmatic decisions and work plan development, increased awareness of the permitted coal mining operations throughout the United States and better communication between the RA, other governmental entities, the public, and industry.Coal mining geospatial data shall be obtained from state, tribal, and federal regulatory authorities for SCMO. The coal mining community encompasses all entities directly and indirectly affected by coal mining activities, including industry, environmental groups, the general public, and the government at all levels within the United States. Use of this standard will help create consistent maps and increase understanding of SCMO sites throughout the United States. This standard promotes the creation of well organized and easily accessible coal mining data, and it will facilitate better communication between state and federal offices, the public, industry, and environmental groups.Within its area of exclusive jurisdiction, each RA is the ADS for coal mining spatial data that it creates and uses to regulate mining activity.This geospatial data standard will help ensure uniformity of data contributed by each RA and assist organizations in efforts to create, utilize, and share geospatial data relative to SMCRA and it will lead to better communication between state, tribal, and federal regulatory offices, the public, and industry.In addition to a defining ERML, this standard over time will allow identification of changes in the ERML’s as the mined area changes.Participation in the compilation of spatial data is not uniform across RAs, which may affect completeness, both in terms of spatial data, and associated attributes.This standard conforms to the definition of a Data Content Standard as promulgated by the U.S. Federal Geographic Data Committee (FGDC). Terminology and definitions for identifying geographical features and describing the data model has been adopted from the FGDC Spatial Data Transfer Standard (ANSI INCITS 320-1998 (R2003)) and the FGDC Framework Data Content Standard (FGDC Project 1574-D) and other geographic area boundaries.Although this standard is written specifically for the coal mining industry, its general purpose and content are applicable to other mining operations.1.1 This practice covers the minimum elements for the accurate location and description of geospatial data for defining a coal mining environmental resource monitoring location (ERML).1.1.1 This practice addresses coal mining geospatial environmental resource monitoring data relative to the Surface Mining Control and Reclamation Act of 1977 (SMCRA). This geospatial data shall be obtained from each state, tribal, or federal, or combinations thereof, coal mining regulatory authority (RA) authorized under SMCRA to regulate surface coal mining operations (SCMO). Each RA shall be the authoritative data source (ADS) for coal mining geospatial data.1.1.2 As used in this practice, coal mining ERML’s represents points where surface, groundwater, and geologic drill hole chemistry are used to determine any probable hydrologic consequences where coal removal, reclamation and related supporting activities has occurred, is occurring, or is planned and authorized by the RA within a defined SCMO. These locations may also include dam safety, impoundments, diversions, air quality, air blasts (blasting), construction (refuse piles), and subsidence.1.1.3 This standard is one of several that have been approved or are in development related to SMCRA approved coal mining operations.

This practice addresses coal mining geospatial boundary data relative to the SMCRA and 30 CFR Part 700 et seq. This practice is significant to the coal mining community because it provides uniformity of geospatial data pertaining to surface coal mining boundaries throughout the United States. The surface coal mining boundary is the first of the coal mining geospatial data standards to be developed for use by a RA. Within its area of exclusive jurisdiction, each RA is the authoritative data source (ADS) for coal mining spatial data that it creates and uses to implement SMCRA. These standards will help ensure uniformity of coal mining geospatial data used in internal business practices, exchanged among business partners within the coal mining community, and contributed by each ADS in future efforts to create national datasets describing surface coal mining in the United States. Note 1—Currently, not all RAs have established datasets for coal mining geospatial data. Of those RAs that have coal mining geospatial datasets, each organizes their data in a different method, using their own coordinate system, and their own naming conventions and terminology. By establishing national data standards, RAs will have uniform guidance for the creation and management of coal mining geospatial data. In effect, this practice creates an easier and more efficient way to utilize and share surface coal mining boundary geospatial data among affected parties. Surface coal mining geospatial data shall be obtained from State and Federal regulatory authorities for SCMO. The coal mining community encompasses all entities directly and indirectly affected by coal mining activities, including industry, environmental groups, the general public, and the government at all levels within the United States. Use of this standard will help create consistent maps and increase understanding of SCMO sites throughout the United States. This standard promotes the creation of well organized and easily accessible surface coal mining data, and it will facilitate better communication between state and federal offices, the public, industry and environmental groups. In addition to defining a permit boundary, use of this standard over time will allow identification of changes in the boundary as the mined area changes. Among a few coal-producing states, some attributes of the surface coal mining boundaries will not have values. A national dataset of surface coal mining boundaries will appear to be incomplete for certain states. In some situations, surface coal mining geospatial data may not have been collected for those states. In others, it is not applicable. This standard conforms to the definition of a Data Content Standard as promulgated by the U.S. Federal Geographic Data Committee (FGDC). Terminology and definitions for identifying geographical features and describing the data model has been adopted from the FGDC Spatial Data Transfer Standard (ANSI INCITS 320-1998 (R2003)) and the FGDC Framework Data Content Standard (FGDC Project 1574-D) Information TechnologyGeographic Information Framework Data Content Standard, Part 5: Governmental Unit and Other Geographic Area Boundaries. Although this standard is written specifically for the surface coal mining industry, its general purpose and content are applicable to other surface mining operations.1.1 This practice covers the minimum elements for the accurate location and description of data for defining a surface coal mining permit boundary. 1.1.1 This practice addresses coal mining geospatial boundary data relative to the Surface Mining Control and Reclamation Act of 1977 (SMCRA). This geospatial data shall be obtained from each state or federal, or both, coal mining regulatory authority (RA) authorized under SMCRA to regulate surface coal mining operations (SCMO). Each RA shall be the authoritative data source (ADS) for coal mining geospatial data. 1.1.2 As used in this practice, a surface coal mining permit boundary represents an area where coal removal and reclamation and related supporting activities have occurred, is occurring, or is planned and authorized by the RA within a defined SCMO. 1.2 This practice is limited to surface coal mining operations after passage of SMCRA. 1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. 1.4 This practice offers a set of instructions for performing one or more specific operations. This document cannot replace education or experience and should be used in conjunction with professional judgment. Not all aspects of this practice may be applicable in all circumstances. This ASTM standard is not intended to represent or replace the standard of care by which the adequacy of a given professional service must be judged, nor should this document be applied without consideration of a project’s many unique aspects. The word “Standard” in the title of this document means only that the document has been approved through the ASTM consensus process.

This practice addresses underground coal mining extent geospatial data relative to the Surface Mining Control and Reclamation Act of 1977 (SMCRA) and 30 CFR Part 700 et seq. This practice is significant to the coal mining community because it provides for uniformity of geospatial data pertaining to underground coal mine extents for mines located throughout the United States. These standards will help ensure uniformity of data contributed by each RA and assist organizations in future efforts to create and utilize geospatial data relative to underground coal mining extents in the United States. The first standard developed is Practice D7384, Practice for Minimum Geospatial Data for a Coal Surface Mining Permit Boundary.Underground mine geospatial data shall be obtained from State and Federal regulatory authorities for underground mining extents. The coal mining community encompasses all entities directly and indirectly affected by coal mining activities, including industry, environmental groups and the government at all levels within the United States. Use of this standard will help create consistent maps and increase awareness of underground mining extents throughout the United States. This standard creates well organized and easily accessible underground coal mining extents data, and it will lead to better communication between the RAs and federal offices, the public, industry and environmental groups.As used in this practice, the geospatial data represents an area where coal removal occurred within a defined UCMO. An underground mine extent is defined as a polygon or polygons. A lack of data from any RA will create a gap in the national underground mining extents geospatial data set. This national coal mining data set consists of underground coal mining extents data from each RA, which will show the locations of underground coal mines throughout the United States. Currently, each coal producing state organizes their data in a different method, and their own naming conventions and terminology. By establishing national geospatial data standards, guidance is provided to RA coal mining programs that do not have any geospatial data standards of their own. This practice creates an easier and more efficient way to utilize and share underground mining extent geospatial data between RAs and the coal mining community.If there is a lack of uniform practices among RAs, certain attributes of the underground coal mining extents data may not be present in some RAs's geospatial data. If this is the case, the finished data set for underground coal mining extents will appear to be incomplete for certain states, but in reality, some underground coal mining extents geospatial data will not be collected for those states, since it may not be applicable to them.This standard conforms to the definition of a Data Content Standard as promulgated by the U.S. Federal Geographic Data Committee (FGDC). Terminology and definitions for identifying geographical features and describing the data model have been adopted from the FGDC Spatial Data Transfer Standard and the FGDC Framework Data Content Standard (FGDC Project 1574–D) Information TechnologyPart 5 Governmental unit and other geographic area boundaries.Although this standard is written specifically for the underground coal mining industry, its general purpose and content may be applicable to other underground mining extents.1.1 This practice covers the minimum elements for the accurate location and description of data for defining underground coal mining extents.1.1.1 This practice addresses coal mining geospatial data relative to the Surface Mining Control and Reclamation Act of 1977 (SMCRA). This geospatial data shall be obtained from each state, tribal, or federal (or combinations thereof) coal mining regulatory authority (RA) authorized under SMCRA to regulate the surface effects of underground coal mining operations (UCMO).1.1.2 As used in this practice, underground coal mining extents represent an area where coal removal has occurred within a defined UCMO.1.2 This practice applies to pre-SMCRA and post-SMCRA underground coal mining extents.1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.1.5 This practice offers a set of instructions for performing one or more specific operations. This document cannot replace education or experience and should be used in conjunction with professional judgment. Not all aspects of this practice may be applicable in all circumstances. This ASTM standard is not intended to represent or replace the standard of care by which the adequacy of a given professional service must be judged, nor should this document be applied without consideration of a project’s many unique aspects. The word “Standard” in the title of this document means only that the document has been approved through the ASTM consensus process.

4.1 This practice addresses coal mining geospatial data in general and is significant to the coal mining community because it provides uniformity of geospatial data pertaining to coal mining features.4.2 Some RA data for coal mining feature attributes may not have values. Those RAs may not collect those attributes as part of their regulatory program or those attributes may not be applicable within their area of responsibility. As a result, a national dataset of coal mining features may appear to be incomplete for those RAs.4.3 Within its area of exclusive jurisdiction, each RA is the ADS for the coal mining geospatial data that it creates and uses to regulate mining activity.4.4 Limitations of Use—Uses of a national dataset are limited by several factors affecting the completeness, currency, and accuracy, of various data sources.4.4.1 Completeness—Participation in the compilation of spatial data may not be uniform across RAs, which may affect completeness, both in terms of spatial data, and associated attributes. For some RAs, this standard may not be applicable because features described herein do not occur within their area of responsibility.4.4.2 Currency—Source data is subject to change as a result of regulatory actions that may change the geographical location, extent, or attributes of particular features which may not be reflected in the national dataset. If detailed information is needed for individual features, the appropriate RA should be contacted for additional information.4.4.3 Data compiled in accordance with this standard is not intended to be used as a primary source for evaluating risk or safety.4.4.4 Data compiled in accordance with this standard is intended for informative purposes; it is not authoritative.1.1 This practice defines a set of terms, procedures, and data required to define the accurate location and description of the minimum geospatial data for surface coal mining operations (CMO), underground coal mining extents, land reclamation and performance bond statuses, lands unsuitable for mining petitions (LUMP) and designated areas, coal spoil and refuse features, coal preparation plants, environmental resource monitoring locations (ERMLs), and postmining land uses.1.2 Units—The values stated in inch-pound units are to be regarded as standard. No other units of measurement are included in this standard.1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulator limitations prior to use.1.3.1 This practice offers a set of instructions for performing one or more specific operations. This document cannot replace education or experience and should be used in conjunction with professional judgment. Not all aspects of this practice may be applicable in all circumstances. This ASTM standard is not intended to represent or replace the adequacy of a professional service, nor should this document be applied without consideration of a project’s many unique aspects. The word “Standard” in the title of this document means only that the document has been approved through the ASTM consensus process.1.4 Surface CMOs—As used in this practice, a surface CMO represents an area where coal removal, reclamation, and related supporting activities have occurred, is occurring, is pending authorization or is authorized by the Regulatory Authority (RA) within a defined surface CMO or any other unpermitted area that has been identified by the RA.1.4.1 This practice addresses coal mining geospatial data, interim permits, and permanent program permits. Each RA shall be the authoritative data source (ADS) for coal mining geospatial data.1.5 Underground Coal Mining Extents—This practice addresses underground coal mining extents that represent an area where coal removal has occurred within a defined underground CMO.1.6 Land Reclamation Status—This practice addresses the land reclamation status of surface areas within a permitted CMO where coal removal, reclamation and related supporting activities has occurred, is occurring, or is planned and authorized by the RA.1.7 Performance Bond Status—This practice shows the status of coal mine reclamation as outlined by each phase of reclamation. In addition to defining the status of individual areas covered by a performance bond, use of this standard will identify the changes of the reclamation and bond status to mined areas as they change over time. Reference to bond status means performance bond status.NOTE 1: A single bond may cover multiple permits or multiple bonds may cover a single permit.1.8 Lands Unsuitable for Mining Petition—This practice addresses boundary data pertaining to areas that have been petitioned and designated as unsuitable for mining. It also addresses those lands that have been found by the RA’s process to be designated unsuitable for all or certain types of mining. These areas may be petitioned to be unsuitable for CMOs because they meet criterion that include, but are not limited to: fragile, historic, cultural, scientific, having esthetic values and natural systems such as aquifers that could be significantly damaged due to a CMO.1.9 Refuse Structures—This practice addresses excess spoil and refuse features produced by CMOs. These features include excess spoil structures, coal refuse structures, and coal preparation plants.1.9.1 Excess Spoil Structures—These structures are created when the total spoil produced during mining exceeds the volume of material that can be utilized for reclamation. This occurrence is common in steep slope areas, where the final grade of reclaimed slopes is limited by stability requirements. It also occurs where overburden volume is significantly larger than the volume of minable coal. Spoil also exhibits a net increase in volume due to the introduction of void spaces in fragmented rock when overburden is removed to expose underlying coal seams. The production of excess spoil requires the creation of disposal structures that extend outside the mined area.1.9.2 Coal Preparation Plants—Facilities where impurities are removed from coal and potentially crushed, resized, and blended with other grades of coal. Preparation plants produce refuse as a byproduct.1.9.3 Refuse—A waste byproduct of coal processing, generally categorized as either coarse or fine. Fine coal refuse often is handled as a slurry containing a blend of water, fine coal, silt, sand, and clay particles.1.9.4 Impounding Refuse Structures—These structures create a holding area for slurry that allows solids to settle out and water to be recovered. Cross-valley and diked impoundments utilize an embankment, often constructed of coarse coal refuse, which forms a basin for slurry retention, as shown in Fig. 1 and Fig. 2, respectively. Incised impoundments dispose of slurry in an excavated area below the natural surface and do not utilize a significant embankment for slurry retention, see Fig. 3.FIG. 1 Cross Sectional Depiction of a Cross-Valley Refuse Impounding FeatureFIG. 2 Cross Sectional Depiction of a Diked Refuse Impounding FeatureFIG. 3 Cross Sectional Depiction of an Incised Refuse Impounding Feature1.9.5 Non-Impounding Refuse Structures—These structures may contain slurry that has been dewatered and stabilized prior to disposal. Non-impounding slurry cells are used to dispose of fine refuse. Methods that significantly reduce the water content of fine coal refuse may allow a refuse structure to avoid being classified as an impoundment.1.10 ERML—This practice addresses locations where monitoring and sampling (such as water, air, soil sampling, and subsidence or air blasting monitoring) has occurred, is occurring, or is planned.1.11 Postmining Land Uses—This practice describes data required to locate and identify postmining land uses for surface coal mining and reclamation operations. Postmining land use may include cropland, pasture/hayland, grazing land, forest, residential, fish and wildlife habitat, developed water resources, public utilities, industrial/commercial, and recreation.1.12 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
