Remediation of Leaking Underground Storage Tanks (LUST) is estimated to cost more than $41 billion in the United States. As of May 1992, 1.5 million Underground Storage Tanks were registered in USA. By September 1992, 184,000 confirmed releases (leaks) were reported in USA. Due to such a vast impact on the environment due to leaking USTS, United States Environmental Protection Agency (USEPA) published final UST regulations in the Federal Register on September 23,1988 (40CFR Part 280) which affected almost every commercial underground storage tank (UST). In a rush to comply with UST regulations, it is important that sufficient attention has been paid to engineering aspects of the work. Due to wide array of UST leak prevention and detection products available, selection of appropriate instrumentation can be time consuming. Most states have taken federal government standards on USTs and incorporated them as state regulations with their state specific modifications depending on their local geological conditions and environmental priorities. However, it is important to find out that state's UST program has been approved by USEPA. This paper consists of discussion of issues based on the author's UST project related experience from current and previous employment. Following are the major UST related regulatory topics discussed in this paper: Specifications;Hiring a contractor; Piping Selection and Installation; UST Selection and Installation; Leak Detection System Environmental Sampling.
