				2., F.A.C., and be registered with the Department in accordance with subsection
				 62-762.851(2),
				F.A.C. Liners shall not be constructed or consist of naturally occurring
				in-situ soils.
3. Secondary
				containment constructed of concrete shall be:
a. Designed and constructed in accordance
				with ACI 224R-01, (Reapproved 2008), and ACI 350.4R-04, 2004 Edition, both
				incorporated by reference in paragraph
				 62-762.201(33)(b),

				with SSPC-TU 2/NACE 6G197, February 1997, incorporated by reference in
				subparagraph  62-762.201(33)(b) 
				2., F.A.C., unless previously lined in accordance with NACE Standard
				SP0892-2007, (formerly RP0892), 2007 Edition, incorporated by reference in
				sub-subparagraph  62-762.501(1)(b) 
				3.b., F.A.C., and be registered with the Department in accordance with
				subsection  62-762.851(2),
				F.A.C., or
c. Designed, evaluated,
				and certified by a professional engineer licensed in the State of Florida that
				the concrete secondary containment system meets the general construction
				requirements specified in subparagraph
				 62-762.502(1)(b) 
				1., F.A.C.
4. Secondary
				Containment constructed with other materials, including clay liner materials,
				shall be impervious and registered in accordance with subsection
				 62-762.851(2),
				F.A.C.
5. For cathodically
				protected tanks and integral piping, secondary containment systems shall not
				interfere with the operation of the cathodic protection system.
6. For VCI protected tanks, the secondary
				containment system shall provide containment for the vapor corrosion
				inhibitors.
7. Secondary
				containment systems shall be designed and installed to direct any release to a
				monitoring point or points.
8. If
				factory-made containment systems or single-walled sumps are installed on the
				system, a containment integrity test shall be performed in accordance with
				manufacturer's requirements. For system components without manufacturer
				containment integrity testing specifications, PEI/RP1200-19, 2019 Edition,
				incorporated by reference in subparagraph
				 62-762.501(1)(b) 
				8., F.A.C., shall be used before the component is placed into service. For
				field-fabricated components the tests shall be at least for 24 hours in
				accordance with manufacturer's requirements.
9. An interstitial integrity test shall be
				performed on each double-walled or double-bottomed storage tank with a closed
				interstice after it is constructed at the facility, and before the storage tank
				is placed into service. This test shall be performed in accordance with Annex
				I.6, Testing and Inspection, located in API Std 650, March 2020, incorporated
				by reference in subsection
				 62-762.201(67),
				F.A.C.
10. An interstitial
				integrity test shall be performed on double-walled small diameter integral
				piping in contact with the soil, or that transports regulated substances over
				surface waters of the state, in accordance with PEI/RP100-20, 2020 Edition,
				incorporated by reference in subparagraph
				 62-762.501(1)(b) 
				10., F.A.C., and PEI/RP1200-19, 2019 Edition, before the small diameter
				integral piping is placed into service.
(c) Cathodic protection.
1. Test stations. Cathodic protection systems
				shall be designed, constructed, and installed with test stations in accordance
				with NACE standards contained in paragraph
				 62-762.211(2)(g),
				F.A.C., or another method of monitoring to allow for a determination of current
				operating status. Cathodic protection test stations shall provide direct access
				to the soil electrolyte in close proximity to each cathodically protected
				structure for placement of reference electrodes, and monitoring wires that
				connect directly to cathodically protected structures. Facilities where direct
				access to soil in close proximity to cathodically protected structures is
				present, and where electrical connections to cathodically protected structures
				can be conveniently accomplished, need not have separate dedicated cathodic
				protection test stations.
2. The
				cathodic protection system shall be operated and maintained in accordance with
				subsection  62-762.702(2),
				F.A.C.
3. Any field-installed
				cathodic protection system shall be designed and installed by or under the
				direction of a Corrosion Professional.

				Inhibitors (VCI).
1. Testing locations for
				vapor corrosion inhibitors. Vapor Corrosion Inhibitor technologies, registered
				with the Department in accordance with subsection
				 62-762.851(2),
				F.A.C., provide an alternative to cathodic protection for protection of metal
				surfaces within the secondary containment. VCI effectiveness shall be
				established by the use of electrical resistance probes located in testing
				locations as recommended by a Corrosion Professional to monitor corrosion
				rates.
2. Any field-installed VCI
				protection system shall be designed and installed by, or under the direction
				of, a Corrosion Professional and the VCI manufacturer's certified installer.
				The VCI protection system shall be operated and maintained in accordance with
				subsection  62-762.702(3),
				F.A.C.

				The primary and secondary walls of storage tank systems shall be made of, or
				internally lined with, materials that are compatible with the regulated
				substance stored in the storage tank systems and with substances or conditions
				present in the environment. All storage tank systems containing blends of
				ethanol, biodiesel, or other biofuels and additives shall be compatible with
				regulated substances stored in the storage tank systems.
(f) Exterior coatings. Exterior portions of
				tanks and integral piping shall be coated or otherwise protected from external
				corrosion. The coating shall be designed and applied to resist corrosion,
				deterioration, and degradation of the exterior wall.
(g) All components of a storage tank system
				shall be installed in accordance with the manufacturer's
				instructions.
(h) All storage tank
				systems shall be installed in accordance with the applicable provisions of API
				Std 650, March 2020, incorporated by reference in subsection
				 62-762.201(67),
				F.A.C.; NFPA 30, 2021 Edition, incorporated by reference in paragraph
				 62-762.201(36)(a),

				9., F.A.C.
(i) Whenever integral
				piping in contact with the soil is installed or relocated after January 11,
				2017, a survey drawing of the underground integral piping, signed and sealed by
				a professional land surveyor or professional engineer licensed in the State of
				Florida, shall be completed and maintained as a record in accordance with Rule
				 62-762.711,
				F.A.C.
