Abstract Since 1994, there has been a significant regulatory shift toward risk‐based cleanup standards based on the site‐specific risk of the more toxic and mobile compounds; namely, benzene, ethyl benzene, toluene, and xylene (BTEX). This regulatory shift has been accompanied by a growing acceptance of natural attenuation as an important component of petroleum site remediation. This article briefly reviews regulatory progress toward risk‐based remediation and describes the successful application of risk‐based corrective actions (RBCAs) at two fuel contaminated sites on Air Force installations. By developing site‐specific cleanup goals, and combining natural attenuation, source reduction, and land use controls, innovative risk‐based closure plans have been implemented on these sites.
