Cleanup of Underground Storage Tank Releases Using Pump and Treat Methods

摘要

The report is part of the National Network for Environmental Management Studies under the auspices of the Office of Cooperative Environmental Management of the US EPA. The task posed for the NNEMS project was to identify Underground Injection Control (UIC) and Underground Storage Tank (UST) information in order to develop a Memorandum of Understanding (MOU), and an UST owner/operator informational brochure for US EPA Region III. Under current regulations, when an owner/operator is faced with a leaking UST, cleanup is required. If a pump and treat method is used and involves treatment of contaminated ground water and reinjection through a well, a permit may be required. Because permits for remediation wells had not been issued in the past for leaking USTs, an understanding of the number and types of corrective action at leaking UST sites was required. A brochure was created for owners/operators of USTs and environmental consultants involved in cleanups. A fact sheet was developed as an in-house tool to inform both the UST and UIC sections. The MOU between the Water Management and Hazardous Waste Management Divisions contain language necessary to provide an information link between UIC and UST sections; however, much of the MOU is not implemented to date. Implementation of the current MOU should satisfy the goals of this project.
