				surfaces within the secondary containment. Vapor corrosion inhibitors (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
				 62-762.701(3),
				F.A.C.
(e) 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
				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.
