STANDARDS FOR INTEGRITY ASSESSMENT FOR EXISTING TANK(S). At a minimum, the structural integrity assessment for each tank system(s) shall include an evaluation of the following: 1. Design standards, if available, according to which the tank and ancillary equipment such as sumps, cut-off valves, and piping to cut-off valves were constructed; 2. Hazardous characteristics of the hazardous or radioactive substance(s) that have been or will be handled; 3. Existing corrosion protection measures; 4. Documented age (if unavailable, an estimated age) of the tank system(s); and 5. Results of an integrity examination, either (a) a leak test that is capable of taking into account the effects of temperature variations, tank end deflection, vapor pockets, and high water table effects, or (b) other integrity examination that addresses cracks, leaks, corrosion, and erosion, and that documents the limits of the technique(s) used to examine tank integrity and is certified by a registered professional engineer.
