2、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
3、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
4、 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-pretat
