Current through Reg. 50, No. 138; July 16, 2024
(1) Out-of-service
				storage tank systems.
(a) Storage tank
				systems that are taken out-of-service, as required in this subsection shall
				continue to be maintained in accordance with this chapter unless otherwise
				noted herein.
(b) Facility owners
				and operators of out-of-service storage tank systems shall:
1. Continue to operate and maintain corrosion
				protection in accordance with subsection
				 62-762.701(2),
				F.A.C.,
2. Continue to maintain and
				demonstrate financial responsibility pursuant to Rule
				 62-762.421, F.A.C.,
3. Leave vent lines open and functioning,
4. Remove all regulated substances
				so that no more than one inch in depth or 0.3 percent by weight of the
				regulated substances remains in the storage tank,
5. Secure or close off the system to outside
				access,
6. Register the storage
				tank system out-of-service in accordance with Rule
				 62-762.401, F.A.C.; and,
7. Perform a visual inspection
				annually, not to exceed 12 months, of every component of a storage tank system
				that contains, transfers, or stores, or is designed to contain, transfer, or
				store regulated substances, that can be visually inspected. Each annual visual
				inspection of the storage tank system shall be documented as to its condition
				pursuant to Rule  62-762.711, F.A.C., and will be
				deemed timely if performed within the same calendar month in which the test is
				due. Any visual inspection of a storage tank system that reveals uncontrolled
				pitting corrosion, structural damage, leakage, or other similar problems is
				considered a positive response. The positive response shall be recorded as part
				of the release detection records and reported and investigated as an incident
				pursuant to Rule  62-762.431, F.A.C. If it is
				determined that a release has occurred while the system is out-of-service; and,
a. The incident investigation reveals a
				release has led to a discharge while the storage tank system is out-of-service
				and storing regulated substances at no more than one inch in depth or 0.3
				percent by weight of total system capacity, then the response to the discharge
				shall be in accordance with paragraphs
				 62-762.441(6)(a), (b), (e), (f), and
				(g), F.A.C. Repairs shall be made within 365
				days of the discharge discovery in accordance with paragraphs
				 62-762.701(1)(a), (c), (d), (e), and
				(f), F.A.C. If the system cannot be repaired
				within 365 days after the discovery of the discharge, it shall be permanently
				closed pursuant to subsection
				 62-762.801(2),
				F.A.C.
b. The incident
				investigation reveals a release has not led to a discharge while the storage
				tank system is out-of-service, then repairs shall be made in accordance with
				paragraphs  62-762.701(1)(a), (c), (d), (e), and
				(f), F.A.C., prior to bringing the storage
				tank system back into service.
(c) The following inspections and testing
				requirements are not required while the storage tank system is properly
				out-of-service:
1. Monthly visual inspections
				in accordance with paragraph
				 62-762.601(1)(e),
				F.A.C.,
2. Semiannual inspections
				of piping and dispenser sumps that use electronic release detection methods in
				accordance with paragraph
				 62-762.601(1)(e),
				F.A.C.,
3. Monthly inspection of
				electronic release detection devices in accordance with paragraph
				 62-762.601(1)(g),
				F.A.C.; and,
4. Release detection
				device annual operability testing, containment and integrity testing, and
				annual overfill protection device testing; however, all aforementioned testing
				shall be current in accordance with this chapter and indicate proper operation
				before adding regulated substances to the storage tank system. In addition,
				storage tank systems that have been out-of-service for more than 365 days must
				be evaluated in accordance with the following prior to being returned to
				service:
a. STI SP001, January 2018,
				incorporated by reference in subsection
				 62-762.411(3),

				and,
b. Integrity tested in
				accordance with Rule  62-762.701, F.A.C., for integral
				piping in contact with the soil.
(d) Storage tank systems with secondary
				containment, not requiring repairs pursuant to Rule
				 62-762.701, F.A.C., shall only
				be designated as out-of-service for a maximum of 10 continuous years. Upon
				expiration of this time period, the storage tank system must be closed in
				accordance with paragraph
				 62-762.801(2)(b),
				F.A.C.
