(EPA 510-B-93-005). November 1993.

This 12-page booklet explains the federal and state laws that require underground storage tanks (USTs) to be equipped with leak detection systems. Although much attention has been focused on large USTs, it is important that leaks from smaller tanks (generally less than 2,000 gallons of capacity) also have leak detection systems. This booklet provides simple, easy to follow, step-by-step directions for the correct way to conduct manual tank gauging for these smaller tanks.
