Section 320. Permanent closure and changes-in-service

Owners and operators must obtain a permit and the required inspections in accordance with the Virginia Uniform Statewide Building Code (§ 36-47 et seq. of the Code of Virginia).

A permit from the building official must be obtained prior to permanent tank closure or a change-in-service. No UST system shall be permanently closed or changed-in-service unless and until the system is inspected in accordance with the provisions of the Virginia Uniform Statewide Building Code (§ 36-47 et seq. of the Code of Virginia).

If such closure is in response to immediate corrective actions that necessitate timely tank removal, then the building official must be notified and the official's directions followed until a permit is issued.

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.

1. Owners and operators must within 30 days after either permanent closure or a change-in-service submit an amended UST notification form (Appendix I) to the board.

2. The required assessment of the excavation zone under 9VAC25-580-330 must be performed after notifying the building official but before completion of the permanent closure or a change-in-service.

3. To permanently close a tank, owners and operators must empty and clean it by removing all liquids and accumulated sludges. When the owner or operator suspects that the residual sludges are hazardous in nature the Department of Environmental Quality regulations shall be followed to facilitate the proper treatment, storage, manifesting, transport, and disposal. All tanks taken out of service permanently must also be either removed from the ground or filled with an inert solid material.

4. Continued use of an UST system to store a nonregulated substance is considered a change-in-service. Before a change-in-service, owners and operators must empty and clean the tank by removing all liquid and accumulated sludge and conduct a site assessment in accordance with 9VAC25-580-330.
