This article describes a relatively new approach to prevent the accidental leakage
of cargo from both aboveground storage tanks (ASTs) and underground storage tanks (USTs). According to the American Petroleum Institute (API), North America houses over 700,000 petroleum tanks.1 Also, the U.S. Environmental Protection Agency (EPA) states there are 1.5 million ASTs.2 Several government officials and state legislatorsstipulate that leak control monitoring systems are the only acceptable way to prevent tanks from leaking into the water table and navigable waters.
The cost of even small and undetected leaks is significant: up to 8,700 gallons/year/tank (33,060 liters/year/tank) for a one-gallon/hour (3.8-liter/hour) leak
that is almost impossible to detect with traditionally available equipment.3 The Resource Conservation and Recovery Act (RCRA), the Oil Pollution Act (OPA 90), and the Clean Water Act all have regulations on ASTs.4 If industries do not become more proactive with spill and leak concerns, large fines may be levied and offenders
may be closed down. In the EPA Liner Study: Report to Congress5, four liner systems were investigated with respect to enhancing secondary containment under and around ASTs and USTs: soil, synthetic geomembrane, coated concrete, and steel.
