Nationwide, the Department of Defense (DOD) is estimated to have over 30,000 un-derground storage tanks (USTs); the Army alone has more than 20,000. Federal regulations (40 CFR 280-281) require that all these tanks be brought into regulatory compliance to avoid environmental contamination. However, replacing all existing USTs is prohibitively expensive. Cost-effective, reliable assessment methods are needed to support informed decisions on UST management, especially in determining alternatives to replacement such as tank lining and external cathodic protection. |
