Expedited Site Assessment Tools for Underground Storage Tank Sites: A Guide for Regulators

(EPA 510-B-97-001, March 1997 and EPA 510-B-16-004, October 2016)

This document, first issued in 1997, discusses the expedited site assessment process, which is a framework for rapidly characterizing UST site conditions for corrective action decisions. This concept has been described with other names including: accelerated site characterization, rapid site characterization, and expedited site investigation. In October 2016, EPA revised the document by updating Chapter V - Direct Push Technologies. The entire document carries the same title but a new number: EPA 510-B-16-004.
