Virginia Administrative Code › Title 9 - ENVIRONMENT › Agency 25 - STATE WATER CONTROL BOARD › Chapter 580 - UNDERGROUND STORAGE TANKS: TECHNICAL STANDARDS AND CORRECTIVE ACTION REQUIREMENTS › Part VII - Out-of-Service UST Systems and Closure › Section 9VAC25-580-320 - Permanent closure and changes-in-service

Current through Register Vol. 40, No. 24, July 15, 2024
Owners and operators must obtain a permit and the required
					 inspections in accordance with 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 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 (§ 36-97 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 to the department.
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 be
				  removed from the ground, filled with an inert solid material, or closed in
				  place in a manner approved by the department.
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.
