New Guide for Advancing Stalled Corrective Action Sites Toward Site Closure

1. Scope

The promotion of knowledge, stimulation of research, and development of standard guides, specifications, practices, test methods, classifications, and definitions relating to environmental assessment, risk management and corrective action. The scope of the Committee includes, but is not limited to multi-media environmental assessment and risk management issues including environmental assessment, environmental management, corrective action due diligence, and sustainability.
These activities will be coordinated with and if available use the standards of other ASTM technical committees and organizations whose fields of endeavor are closely allied to or compliment environmental assessment and environmental management.


RBCA, petroleum, risk based corrective action


There are over 62,000 leaking underground storage tank remediation sites remaining to be cleaned up and closed in the US. The goal of this guide will be to provide a framework (and tools) for assisting and addressing uncertainties in the determination of when a petroleum UST site remediation is ready to close and when a remediation project is off track and needs to be rethought. Many of the remaining sites have had limited assessment and remedial action for a variety of reasons, such as being too low on the states priority list or risk ranking to receive funding, unknown or unwilling responsible parties, and access issues. Others have been in monitored natural attenuation status for many years. Some sites have had significant cleanup activities, have stable groundwater plume concentrations and are unlikely to reach a receptor, but the on-site concentrations are still above the sites target cleanup levels. Still others, despite significant remedial efforts are not stable and may be continuing to threaten human health and the environment. Guidance is needed to help raise awareness within the regulatory and practitioner communities of best practices, based on the latest scientific understanding for the systematic review of remedial progress and facilitation of UST site closure.

The title and scope are in draft form and are under development within this ASTM Committee.
