Section 310. Temporary closure

Part VII. Out-of-Service UST Systems and Closure

Owners and operators must obtain a permit and the required inspections in accordance with the provisions of the Virginia Uniform Statewide Building Code (§ 36-97 et seq. of the Code of Virginia).

A permit from the building official must be obtained prior to temporary tank closure. No UST system shall be temporarily closed unless and until the system is inspected in accordance with the provisions of the Virginia Uniform Statewide Building Code (§ 36-97 et seq. of the Code of Virginia).

In the case of state-owned facilities the Department of General Services shall function as the building official in accordance with § 36-98.1 of the Code of Virginia.

In the case of federal facilities the building official must be contacted. Owners and operators must obtain a permit and the required inspections in accordance with the provisions of the Virginia Uniform Statewide Building Code (§ 36-97 et seq. of the Code of Virginia).

1. When an UST system is temporarily closed, owners and operators must continue operation and maintenance of corrosion protection in accordance with 9VAC25-580-90, and any release detection in accordance with Part IV. Parts V and VI must be complied with if a release is suspected or confirmed. However, release detection is 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% by weight of the total capacity of the UST system, remain in the system.

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, manways, 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 9VAC25-580-50 for new UST systems or the upgrading requirements in 9VAC25-580-60, except that the spill and overfill equipment requirements do not have to be met. Owners and operators must permanently close the substandard UST systems at the end of this 12-month period in accordance with 9VAC25-580-320 through 9VAC25-580-350, unless the building official provides an extension of the 12-month temporary closure period. Owners and operators must complete a site assessment in accordance with 9VAC25-580-330 before such an extension can be applied for.
