3. Metallic double-walled integral piping constructed of nonferrous materials such as copper shall be constructed in accordance with the requirements in Chapter 27 of NFPA 30, 2021 Edition, incorporated by reference in paragraph 62-762.201(36)(a), F.A.C.

4. Integral double-walled piping constructed of other materials, design, or corrosion protection shall be registered with the Department in accordance with subsection 62-762.851(2), F.A.C.

5. Small diameter integral piping using corrosion protection systems with vapor corrosion inhibitors that are registered in accordance with subsection 62-762.851(2), F.A.C., shall be designed and installed under the direction of a Corrosion Professional, and shall be installed with at least one electrical resistance probe or a method of monitoring to allow for a determination of the corrosion rate within the piping interstice. The VCI system shall be designed and installed in accordance with the requirements specified in subsection 62-762.701(3), F.A.C.

(d) Valves.

1. Shear valves. Pressurized small diameter integral piping systems connected to dispensers shall be installed with shear valves or emergency shutoff valves in accordance with Section 6.3 of NFPA 30A, Code for Motor Fuel Dispensing Facilities and Repair Garages, Requirements for Dispensing Devices, 2021 Edition. NFPA 30A is incorporated by reference in subparagraph 62-762.501(1)(h) 2., F.A.C. These valves shall be designed to close automatically if a dispenser is displaced from its normal position. The valves shall be rigidly anchored independently of the dispenser. The valves shall be tested in accordance with PEI/RP1200-19, 2019 Edition, incorporated by reference in subparagraph 62-762.501(1)(b) 8., F.A.C., at the time of installation by a certified contractor to confirm that the automatic closing function of the valve operates properly, and that the valve is properly anchored.

2. Isolation block valves. Any storage tank system, regardless of the date of installation of the storage tank system, located at an elevation that produces a gravity head on small diameter integral piping positioned below the product level in the tank must be installed and maintained with an isolation block valve in accordance with Chapter 22.13 of NFPA 30, 2021 Edition, Flammable and Combustible Liquids Code, Tank Openings Other Than Vents. NFPA 30 is incorporated by reference in paragraph 62-762.201(36)(a), F.A.C.
