Section V-1903 - Assessment of Existing Tank System's Integrity

A. For each existing tank system that does not have secondary containment meeting the requirements of LAC 33:V.1907.B-I, the owner or operator shall determine that the tank system is not leaking or is fit for use. Except as provided in Subsection C of this Section, the owner or operator shall obtain and keep on file at the facility a written assessment reviewed and certified by an independent, qualified professional engineer, in accordance with LAC 33:V.513, that attests to the tank system's integrity by November 20, 1988. Tanks excluded from permitting requirements under LAC 33:V.1015.B.2 must have an assessment as described in this Section by November 20, 1990.

B. This assessment must determine that the tank system is adequately designed and has sufficient structural strength and compatibility with the waste(s) to be stored or treated, to ensure that it will not collapse, rupture or fail. At a minimum, this assessment must consider the following:

1. design standards(s), if available, according to which the tank and ancillary equipment were constructed;

2. hazardous characteristics of the waste(s) that have been and will be handled;

3. existing corrosion protection measures;

4. documented age of the tank system, if available (otherwise, an estimate of the age); and

5. results of a leak test, internal inspection or other tank integrity examination such that:

a. for non-enterable underground tanks, the assessment must include 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; and

b. for other than non-enterable underground tanks and for ancillary equipment, this assessment must include either a leak test, as described above, or other integrity examination, that is certified by an independent, qualified professional engineer in accordance with LAC 33:V.513, that addresses cracks, leaks, corrosion and erosion;

c. tank systems that store or treat materials that become hazardous wastes subsequent to July 14, 1986, must conduct this assessment within 12 months after the date that the waste becomes a hazardous waste;

d. if, as a result of the assessment conducted in accordance with LAC 33:V.1903.A, a tank system is found to be leaking or unfit for use, the owner or operator must comply with the requirements of LAC 33:V.1913.

C. Tank systems that store or treat materials that become hazardous wastes subsequent to July 14, 1986, shall conduct this assessment within 12 months after the date that the waste becomes a hazardous waste.

D. If, as a result of the assessment conducted in accordance with LAC 33:V.1903.A, a tank system is found to be leaking or unfit for use, the owner or operator shall comply with the requirements of LAC 33:V.1913.
