Florida Administrative Code › 62 - DEPARTMENT OF ENVIRONMENTAL PROTECTION › 62 - Departmental › Chapter 62-762 - ABOVEGROUND STORAGE TANK SYSTEMS › Section 62-762.602 - Release Detection Requirements for Field Erected Storage Tank Systems

Current through Reg. 50, No. 138; July 16, 2024
(1) General requirements.
(a) Storage tank systems shall have a method
				or combination of methods of release detection that can detect a new release
				from any portion of the storage tank system.
(b) Any storage tank system without a method,
				or combination of methods, of release detection in accordance with this
				section, shall immediately provide a method of release detection, or
				immediately empty the storage tank system and place the affected system
				out-of-service, or close the system in accordance with subsection
				 62-762.802(3),
				F.A.C.
(c) Any component of a
				storage tank system with an interstice shall have a method of interstitial
				monitoring which shall be conducted in accordance with this section.
				Interstitial monitoring can be performed with vacuum, pressure, hydrostatic
				(liquid-level sensing), sensors or probes, or visual release detection
				methods.
(d) Except as otherwise
				specified in this Rule, the release detection method or combination of methods
				used at a facility shall be performed at least once every calendar month, but
				not exceeding 35 days, to determine if a release from the storage tank system
				has occurred.
(e) Visual
				inspections. At least once a month, but not exceeding 35 days, every component
				of a storage tank system that contains, transfers, or stores, or is designed to
				contain, transfer, or store regulated substances can be inspected visually
				shall be visually inspected and documented as to its condition pursuant to Rule
				 62-762.711, F.A.C. 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. Repairs shall
				be made in accordance with Rule
				 62-762.702, F.A.C. A visual
				inspection is not required for any system component using an electronic release
				detection method.
(f) Electronic
				and mechanical release detection devices shall be:
1. Installed, calibrated, operated, and
				maintained in accordance with the manufacturer's instructions, and shall be
				designed and installed to provide service checks for operability to ensure that
				the device is functioning in accordance with subsection
				 62-762.702(4),
				F.A.C.; and,
2. Registered in
				accordance with subsection
				 62-762.851(2),
				F.A.C., except that controllers or annunciators that are used to display leak
				detection test results are not required to be registered.
(g) Electronic release detection devices
				shall be inspected for proper operation at least once every calendar month, but
				not exceeding 35 days. A record or summary of the alarm history, sensor status,
				and testing results related to suspected releases shall be printed from any
				electronic release detection device. If the release detection system is not
				capable of printing records, a manual log shall be maintained of the alarm
				history, sensor status, and testing results.
(h) Release detection shall be constructed
				and installed so that groundwater, rainfall, or soil moisture will not render
				the release detection method used inoperable.
(i) Storage tank systems containing high
				viscosity product are exempt from all release detection requirements except for
				visual inspections.
