Florida Administrative Code › 62 - DEPARTMENT OF ENVIRONMENTAL PROTECTION › 62 - Departmental › Chapter 62-761 - UNDERGROUND STORAGE TANK SYSTEMS › Section 62-761.600 - Release Detection Requirements

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) For any storage tank system without a
				method, or combination of methods, of release detection in accordance with this
				rule, the owner or operator shall immediately provide a method of release
				detection, or shall immediately empty and place the storage tank system
				out-of-service, or close the storage tank system in accordance with subsection
				 62-761.800(2),
				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 rule. Interstitial
				monitoring can be performed with vacuum, pressure, hydrostatic (liquid-level
				sensing), sensors or probes, and 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 that can be inspected visually shall be
				visually inspected and documented as to its condition pursuant to Rule
				 62-761.710, 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. Repairs shall be made in accordance with Rule
				 62-761.700, F.A.C. The positive
				response shall be reported and investigated as an incident pursuant to Rule
				 62-761.430, F.A.C., if it is
				determined that a release has occurred. A monthly visual inspection is not
				required for any system component using an electronic release detection method;
				however, piping and dispenser sumps that use an electronic release detection
				method must also be visually inspected every six months and records kept of the
				visual inspection.
(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
				 62-761.700(3),
				F.A.C.; and,
2. Registered in
				accordance with subsection
				 62-761.850(2),
				F.A.C., except 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 potential releases shall be printed from any
				electronic release detection device and kept, or be provided to the county or
				Department upon request through electronic documentation. 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 that store fuel
				solely for use by emergency power generators installed prior to January 11,
				2017, must meet the release detection requirements of Rule
				 62-761.600, F.A.C., on or before
				October 13, 2018. Storage tank systems that store fuel solely for use by
				emergency power generators installed after January 11, 2017, must meet the
				release detection requirements of Rule
				 62-761.600, F.A.C., at
				installation.
