Section 335-6-15-.33 - Temporary Closure

(1) When an UST system is temporarily closed, owners and operators must:

(a) Continue operation and maintenance of corrosion protection in accordance with rule 335-6-15-.10, and any release detection in accordance with rules 335-6-15-.14 through 335-6-15-.19 and 335-6-15-.48. However, release detection and release detection operation and maintenance testing and inspections in rules 335-6-15-.09, and 335-6-15-.12 through 335-6-15-.19 are not required as long as the UST system is empty. The UST system is empty when all materials have been removed using commonly employed practices so that no more than 2.5 centimeters (one inch) of residue, or 0.3 percent by weight of the total capacity of the UST system, remain in the system. In addition, spill and overfill operation and maintenance testing and inspections in rules 335-6-15-.09, 335-6-15-.12 and 335-6-15-.13 are not required;

(b) Comply with rules 335-6-15-.20 through 335-6-15-.25 if a release is suspected or confirmed; and

(c) Immediately empty and within 90 days either repair in accordance with rule 335-6-15-.12 or permanently close the UST system in accordance with rules 335-6-15-.34, 335-6-15-.35 and 335-6-15-.37 if the UST owner, operator, or Department is aware of the UST system being compromised in any way such that it may release regulated substance.

(2) When an UST system is temporarily closed for three months or more, owners and operators must also comply with the following requirements:

(a) Leave vent lines open and functioning; and

(b) Cap and secure all other lines, pumps, man ways, and ancillary equipment.

(3) When an UST system is temporarily closed for more than 12 months, owners and operators must permanently close the UST system if it does not meet either performance standards in Rule 335-6-15.-.06 for new UST systems or the upgrading requirements in Rule 335-6-15.-.07, except that the spill and overfill equipment requirements do not have to be met. Owners and operators must permanently close the substandard UST systems within 90 days from the end of this 12-month period in accordance with Rule 335-6-15-.34 through 335-6-15-.37, unless the Department provides an extension of the 12-month temporary closure period. Owners and operators must complete a site assessment in accordance with Rule 335-6-15-.26 before such an extension can be applied for.
