Designation:D778020Standard Practice forMinimum Geospatial Data for Representing Coal MiningFeatures1This standard is issued under the fixed designation D7780;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 This practice defines a set of terms,procedures,and datarequired to define the accurate location and description of theminimum geospatial data for surface coal mining operations(CMO),underground coal mining extents,land reclamationand performance bond statuses,lands unsuitable for miningpetitions(LUMP)and designated areas,coal spoil and refusefeatures,coal preparation plants,environmental resource moni-toring locations(ERMLs),and postmining land uses.1.2 UnitsThe values stated in inch-pound units are to beregarded as standard.No other units of measurement areincluded in this standard.1.3 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulator limitations prior to use.1.3.1 This practice offers a set of instructions for performingone or more specific operations.This document cannot replaceeducation or experience and should be used in conjunction withprofessional judgment.Not all aspects of this practice may beapplicable in all circumstances.This ASTM standard is notintended to represent or replace the adequacy of a professionalservice,nor should this document be applied without consid-eration of a projects many unique aspects.The word“Stan-dard”in the title of this document means only that thedocument has been approved through the ASTM consensusprocess.1.4 Surface CMOsAs used in this practice,a surface CMOrepresents an area where coal removal,reclamation,and relatedsupporting activities have occurred,is occurring,is pendingauthorization or is authorized by the Regulatory Authority(RA)within a defined surface CMO or any other unpermittedarea that has been identified by the RA.1.4.1 This practice addresses coal mining geospatial data,interim permits,and permanent program permits.Each RAshall be the authoritative data source(ADS)for coal mininggeospatial data.1.5 Underground Coal Mining ExtentsThis practice ad-dresses underground coal mining extents that represent an areawhere coal removal has occurred within a defined undergroundCMO.1.6 Land Reclamation StatusThis practice addresses theland reclamation status of surface areas within a permittedCMO where coal removal,reclamation and related supportingactivities has occurred,is occurring,or is planned and autho-rized by the RA.1.7 Performance Bond StatusThis practice shows thestatus of coal mine reclamation as outlined by each phase ofreclamation.In addition to defining the status of individualareas covered by a performance bond,use of this standard willidentify the changes of the reclamation and bond status tomined areas as they change over time.Reference to bond statusmeans performance bond status.NOTE1A single bond may cover multiple permits or multiple bondsmay cover a single permit.1.8 Lands Unsuitable for Mining PetitionThis practiceaddresses boundary data pertaining to areas that have beenpetitioned and designated as unsuitable for mining.It alsoaddresses those lands that have been found by the RAs processto be designated unsuitable for all or certain types of mining.These areas may be petitioned to be unsuitable for CMOsbecause they meet criterion that include,but are not limited to:fragile,historic,cultural,scientific,having esthetic values andnatural systems such as aquifers that could be significantlydamaged due to a CMO.1.9 Refuse StructuresThis practice addresses excess spoiland refuse features produced by CMOs.These features includeexcess spoil structures,coal refuse structures,and coal prepa-ration plants.1.9.1 Excess Spoil StructuresThese structures are createdwhen the total spoil produced during mining exceeds thevolume of material that can be utilized for reclamation.Thisoccurrence is common in steep slope areas,where the finalgrade of reclaimed slopes is limited by stability requirements.1This practice is under the jurisdiction of ASTM Committee D18 on Soil andRock and is the direct responsibility of Subcommittee D18.01 on Surface andSubsurface Characterization.Current edition approved Nov.1,2020.Published December 2020.Originallyapproved in 2012.Last previous edition approved in 2012 as D778012.DOI:10.1520/D7780-20.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United StatesThis international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for theDevelopment
