Underground Storage Tanks (USTs)

Automatic Tank Gauging Systems for Release Detection: Reference Manual for Underground Storage Tank Inspectors

(EPA 510-B-00-009). August 2000.

This manual can help state and EPA inspectors of underground storage tanks (USTs) evaluate how well UST owners and operators are using their automatic tank gauging (ATG) systems to comply with release detection requirements. Also, the manual provides handouts that UST inspectors can distribute to UST owners and operators to help them understand the proper operation and maintenance of their ATG systems. In its 140-pages, the manual contains a summary of specifications, based on third-party evaluations, for ATG systems that detect leaks from USTs and their piping. Each summary provides information such as certified detectable leak rate/threshold, test period duration, product applicability, calibration requirements, restrictions on the use of the device, vendor contact information, printing and interpreting reports, and sample reports.
