Designation:D7630/D7630M 10Standard Practice forMinimum Geospatial Data for Postmining Land Uses1This standard is issued under the fixed designation D7630/D7630M;the number immediately following the designation indicates theyear of original adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of lastreapproval.A superscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 This practice describes minimum data required to locateand identify a postmining land use for a surface coal miningand reclamation operation.Statutory language and definitionsare found in Federal regulations 30 CFR 816/817.133 and 30CFR 701.5.1.1.1 These postmining land use designations reflect coalmining reclamation practices relative to the standards set forthin the Surface Mining Control and Reclamation Act of 1977(SMCRA).2Geospatial data associated with postmining landuse shall be obtained from each regulatory authority(RA),which are authorized under SMCRA to regulate surface coalmining operations(SCMO)and reclamation activities withintheir borders.Each RA shall be the authoritative data source(ADS)for coal mining geospatial data.1.2 This standard is one of several that have been approvedor are in development related to SMCRAapproved coal miningoperations.Also under development is a terminology standard.Initial development of these standards is being done on anindividual basis;however,they may be consolidated to reducerepetition of information between them.1.3 This practice is limited to permitted coal mining opera-tions after the passage of SMCRA.1.4 SMCRA identifies land use categories for surface coalmining permits,such as cropland,pasture/hayland,grazingland,forest,residential,fish and wildlife habitat,developedwater resources,public utilities,industrial/commercial,andrecreation.1.5 Postmining land uses for mountaintop removal andsteep slope mining operations with approximate original con-tour(AOC)variances include the following:1.5.1 A mountaintop removal AOC variance may only begranted if the applicant proposes to remove the entire coalseam or seams running through the upper fraction of the hill,ridge,or mountain creating a level plateau or gently rollingcontour with no highwalls remaining,and capable of support-ing the following postmining land uses.1.5.2 The proposed postmining land use for a mountaintopremoval operation with an AOC variance is limited to indus-trial,commercial,agricultural,residential,or public facilityuse.1.5.3 The proposed use constitutes an equal or better eco-nomic or public use compared with the pre-mining use.1.5.4 The proposed use will be compatible with adjacentland uses and existing state and local land use plans.1.5.5 County commissions and other state and federal agen-cies were provided an opportunity to review and comment onthe proposed postmining land use.1.5.6 The application contains a specific plan and assur-ances that the proposed postmining land use will be:1.5.6.1 Compatible with adjacent land uses;practicable withrespect to financing and completing the proposed use;sup-ported by commitments from public agencies where appropri-ate;1.5.6.2 Planned pursuant to a schedule attached to thereclamation plan so as to integrate the mining operation andreclamation with the postmining land use;1.5.6.3 Designed by a registered professional engineer toassure the stability,drainage,and configuration necessary forthe intended use of the site.1.6 UnitsThe values stated in either SI units or inch-pound units are to be regarded separately as standard.Thevalues stated in each system may not be exact equivalents;therefore,each system shall be used independently of the other.Combining values from the two systems may result in non-conformance with the standard.1.7 This practice offers a set of instructions for performingone or more specific operations.This document cannot replaceeducation or experience and should be used in conjunctionwith professional judgment.Not all aspects of this practice may1This 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 May 15,2010.Published June 2010.DOI:10.1520/D7630_D7630M10.2Public Law 95-87,the Surface Mining Control and Reclamation Act of 1977(SMCRA),passed August 3,1977,as amended.1Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959,United States.Copyright ASTM International Provided by IHS under license with ASTM Licensee=University of Nebraska/5967164006 Not for Resale,04/24/2012 16:46:58 MDTNo reproduction or networking permitted without license from IHS-,-,-be applicable in all circumstances.This ASTM standard is notintended to represent or replace the standard of care by whichthe adequacy of a given professional service must be judged,nor should this document be applied without consideration ofa
