Use of the ASTM standard for risk-based corrective action to support no further action at petroleum-impacted sites

In July 1994, the American Society for Testing and Materials (ASTM) published their Emergency Standard Guide for Risk-Based Corrective Action Applied to Petroleum Release Sites (ES 38-94). This document is a decision-making tool designed to help standardize, simplify and expedite the restoration and closure of sites contaminated with petroleum hydrocarbons. To achieve these objectives, ES 38-94 directs the response efforts - site assessment and remediation - toward protection of human health and the environment. This is done using a tiered approach that advances from (1) evaluation of site-specific conditions and risks, to (2) screening risk assessment, to (3) sophisticated risk assessment. Sites already in remediation often require sophisticated risk assessment (Tier III) to advance the restoration/closure process. To aid such assessment, ES 38-94 provides the fate-and-transport models and exposure equations best designed for the evaluation of risks from petroleum release sites. This paper explains the ES 38-94 process, describes the application of the risk assessment models at two leaking underground fuel tank sites in California, and offers suggestions for the future use of risk-based corrective action methodology to support requests for no further action.
