Designation:E 1912 98(Reapproved 2004)Standard Guide forAccelerated Site Characterization for Confirmed orSuspected Petroleum Releases1This standard is issued under the fixed designation E 1912;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(e)indicates an editorial change since the last revision or reapproval.1.Scope1.1 This guide covers a process to rapidly and accuratelycharacterize a confirmed or suspected petroleum release site.This guide is intended to provide a framework for responsibleparties,contractors,consultants,and regulators to streamlineand accelerate the site characterization process or supplementincomplete characterization data.The accelerated site charac-terization(ASC)approach may be incorporated in state andlocal regulations as a cost-effective method of making in-formed corrective action decisions sooner.1.2 This guide describes a process for collecting site char-acterization information in one mobilization,using rapid sam-pling techniques;field analytical methods;and on-site inter-pretation and iteration of field data to refine the conceptualmodel for understanding site conditions as the characterizationproceeds.This information can be used to determine the needfor interim remedial actions;site classification or prioritization,or both;further corrective actions;and active remediation.Theprocess outlined in this guide can be incorporated into existingcorrective action programs,and is organized to be used inconjunction with Guides E 1599 and E 1739.1.3 For guidance concerning contractor health and safetyissues,appropriate federal,state,and local regulations(forexample,Occupational Safety and Health Administration)andindustry standards should be consulted.For sampling qualityassurance/quality control(QA/QC)practices,see references inSection 2.Considerations for field analytical method qualityassurance/quality control are discussed in Section 5.1.4 This guide is organized as follows:1.4.1 Section 1 describes the scope,1.4.2 Section 2 lists Referenced Documents,1.4.3 Section 3 defines Terminology,1.4.4 Section 4 identifies the Significance and Use,1.4.5 Section 5 describes the Accelerated Site Characteriza-tion Process,1.4.6 Appendix X1 identifies Additional Referenced Docu-ments,1.4.7 Appendix X2 provides an Example of a Data QualityClassification System,1.4.8 Appendix X3 contains a list of physical and chemicalproperties and hydrogeologic characteristics applicable to sitecharacterizations,and a list of input parameters and method-ologies for ASTM RBCA Tier 1 and Tier 2 evaluations,and1.4.9 Appendix X4 contains a case study example of theASC process,including a RBCA Tier 1 and Tier 2 evaluation.1.5 The values stated in inch-pound units are to be regardedas the standard.The SI units given in parentheses are forinformation only.1.6 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 regulatory limitations prior to use.2.Referenced Documents2.1 ASTM Standards:2D 5730 Guide to Site Characterization for EnvironmentalPurposes With Emphasis on Soil,Rock,the Vadose Zone,and Ground WaterE 1599 Guide for Corrective Action for Petroleum ReleasesE 1689 Guide for Developing Conceptual Site Models forContaminated SitesE 1739 Guide for Risk-Based Corrective Action Applied atPetroleum Release Sites2.2EPA Documents:USEPA SW 846,Recommended Analytical Procedures,Test Methods for Evaluating Solid Waste-Physical/Chemical Methods3USEPA,Draft Field Methods Compendium,OER 9285.2-113USEPA,Subsurface Characterization and Monitoring Tech-niques:A Desk Reference Guide-Vols I and II,EPA625/R-93/003a and b3USEPA,Description and Sampling of Contaminated Soils:1This guide is under the jurisdiction ofASTM Committee E50 on EnvironmentalAssessment and is the direct responsibility of Subcommittee E50.04 on PerformanceStandards Related to Environmental Regulatory Programs.Current edition approved May 1,2004.Published June 2004.Originally approvedin 1998.Last previous edition approved in 1998 as E 1912 98.2For referenced ASTM standards,visit the ASTM website,www.astm.org,orcontact ASTM Customer Service at serviceastm.org.For Annual Book of ASTMStandards volume information,refer to the standards Document Summary page onthe ASTM website.3Available from Superintendent of Documents,U.S.Government PrintingOffice,Washington,DC 20402.1Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959,United States.A Field Pocket Guide,EPA 625/12-91/0023USEPA,Environmental Investigations Standard OperatingProcedures and Quality Assurance Manual,May 1996,USEPA Region3USEPA,Expedited Site Assessment Tools for UST Sites:AGuide for Regulators,EPA 510
