1、Designation: E1739 95 (Reapproved 2015)Standard Guide forRisk-Based Corrective Action Applied at Petroleum ReleaseSites1This standard is issued under the fixed designation E1739; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the

2、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 is a guide to risk-based corrective action (RBCA),which is a consistent decision-making process for the a

3、ssess-ment and response to a petroleum release, based on theprotection of human health and the environment. Sites withpetroleum release vary greatly in terms of complexity, physicaland chemical characteristics, and in the risk that they may poseto human health and the environment. The RBCA processre

4、cognizes this diversity, and uses a tiered approach wherecorrective action activities are tailored to site-specific condi-tions and risks. While the RBCA process is not limited to aparticular class of compounds, this guide emphasizes theapplication of RBCAto petroleum product releases through theuse

5、 of the examples. Ecological risk assessment, as discussedin this guide, is a qualitative evaluation of the actual orpotential impacts to environmental (nonhuman) receptors.There may be circumstances under which a more detailedecological risk assessment is necessary (see Ref (1).21.2 The decision pr
