Current through Reg. 50, No. 138; July 16, 2024
(1)
				General requirements.
(a) Wellhead Protection.
				Persons are advised that Chapter 62-521, F.A.C., contains restrictions
				regarding the location of storage tank systems within 500 feet of a potable
				water well.
(b) Secondary
				containment.
1. The materials used for
				secondary containment shall be:
a. Impervious
				to the regulated substance being stored in the storage tank system and able to
				withstand deterioration from external environmental conditions,
b. Non-corrosive or of corrosion-protected
				materials or technologies; and,
c.
				Of sufficient thickness and strength to withstand hydrostatic forces at maximum
				capacity to prevent a discharge.
2. For cathodically protected tanks and
				integral piping, secondary containment systems shall not interfere with the
				operation of the cathodic protection system.
3. Secondary containment systems shall be
				designed and installed to direct any release to a monitoring point or
				points.
4. If factory-made
				single-walled spill containment systems or single-walled sumps are installed on
				the system, a containment integrity test shall be performed before the
				component is placed into service in accordance with the manufacturer's testing
				requirements. For system components without manufacturer containment integrity
				testing specifications, PEI/RP1200-19, 2019 Edition shall be used. PEI
				RP1200-19 is the
Recommended Practices for the Testing and Verification
				of Spill, Overfill, Leak Detection and Secondary Containment Equipment at UST
				Facilities,
hereby adopted and incorporated by reference and, as a
				copyright protected document, is available for inspection at the Department of
				Environmental Protection or the Department of State address provided in
				subsection  62-761.210(1),
				F.A.C., or the publisher at PEI, Post Office Box 2380, Tulsa, Oklahoma
				74101-2380, (918)494-9696, or the publisher's website at
www.pei.org/
. For field-fabricated components
				the tests shall be at least for 24 hours in accordance with manufacturer's
				requirements.
5. An interstitial
				integrity test shall be performed on the storage tank after it is delivered and
				installed at the facility and before the storage tank is placed into service.
				This test shall be performed in accordance with manufacturer's requirements.
				For storage tanks without manufacturer's interstitial integrity testing
				specifications, PEI/RP100-20, 2020 Edition shall be used. PEI/RP100-20 is
				hereby adopted and incorporated by reference and, as a copyright protected
				document, is available for inspection at the Department of Environmental
				Protection or the Department of State address provided in subsection
				 62-761.210(1),
				F.A.C., or the publisher at PEI, Post Office Box 2380, Tulsa, Oklahoma

Recommended Practices
				for Installation of Underground Liquid Storage Systems
, PEI/RP100-20,
				2020 Edition; and PEI/RP1200-19, 2019 Edition.
6. An interstitial integrity test shall be
				performed on integral piping in accordance with PEI/RP100-20, 2020 Edition, and
				PEI/RP1200-19, 2019 Edition, before the integral piping is placed into
				service.
7. If double-walled spill
				containment systems or double-walled sumps are installed on the system, an
				interstitial integrity test shall be performed in accordance with the
				manufacturer's testing requirements. For system components without manufacturer
				interstitial integrity testing specifications, PEI/RP1200-19, 2019 Edition
				shall be used before the component 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
				 62-761.210(2)(f),
				F.A.C. 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  62-761.700(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.
4. Cathodic protection is not required for
				any field-fabricated primary storage tank that has been installed within a
				former single-walled storage tank as a means to upgrade to secondary
				containment. However, the former single-walled storage tank, which has now
				become the secondary containment must be protected from corrosion.
5. Supplemental anodes that are added to a
				sti-P3® tank after, January 11, 2017, shall be
				installed in accordance with the following document, regardless of the date of
				installation of the storage tank system or storage tank system component:

				sti-P3® USTs

				or the Department address located in subsection
				 62-761.210(1),
				F.A.C.
(d) Compatibility.
				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
				the regulated substances stored in the storage tank systems. Storage tank
				systems and system components containing ethanol blends greater than 10 percent
				or biodiesel blends greater than 20 percent must demonstrate compatibility
				through registration of the storage tank system and system components in
				accordance with subsection
				 62-761.850(2),
				F.A.C.
(e) All components of a
				storage tank system shall be installed in accordance with the manufacturer's
				instructions.
(f) All storage tank
				systems shall be installed in accordance with the following reference
				guidelines, hereby adopted and incorporated by reference and, as copyright
				protected documents, are available for inspection at the Department of
				Environment Protection or the Department of State address provided in

				Certified Contractor shall perform the installation of storage tank systems
				containing pollutants, including: tanks, integral piping (excluding drop
				tubes), overfill protection and spill containment equipment, internal release
				detection equipment, cathodic protection systems, secondary containment
				systems, and dispensers.
