(a) Scope. This section sets forth standards, requirements and procedures for the design, installation, and installation acceptance testing of the following devices, equipment and systems at liquid motor fuel-dispensing facilities:
(1) cathodic protection systems and coatings for underground storage tanks and piping; and
(2) liquid motor fuel dispensers and pumps.
(b) General Provisions. Cathodic protection systems and motor fuel dispensers and pumps at liquid motor fuel-dispensing facilities shall be designed and installed in accordance with FC Chapter 22 and this section.
(c) Cathodic Protection Systems. Cathodic protection systems for underground storage tanks and piping for liquid motor fuel at liquid motor fuel-dispensing facilities shall be designed and installed in compliance with the following requirements:
(1) Steel storage tanks and piping systems shall be protected against exterior corrosion by either a sacrificial anode or an impressed current cathodic protection system designed in accordance with the applicable National Association of Corrosion Engineers (NACE) standard or other approved standard. Such system shall be designed to provide corrosion protection for not less than 30 years.
(2) Tanks protected by sacrificial anodes shall be electrically isolated from the piping system.
(3) Cathodic protection systems shall be designed by a trained person knowledgeable of the requirements of the United States Environmental Protection Agency for such systems. Such person shall first inspect the site and test the site for soil resistivity and the presence of stray currents. Such cathodic protection systems shall be installed under the personal supervision of such person.
(4) Cathodic protection systems shall be inspected and tested in the presence of a representative of the Department at the time of installation in compliance with the applicable National Association of Corrosion Engineers standard and the following procedures:
(A) All piping shall be subjected to a holiday test and tanks and associated piping shall be subjected to an electrical continuity test. Any holiday located during a spark test shall be repaired as per coating specifications before the tank or piping excavation is backfilled.
(B) Upon completion of the underground motor fuel storage tank installation, the following information and documentation shall be submitted to the Department:
(1) An "as-built" drawing showing number, size (weight) and location of all anodes and test stations.
(2) An affidavit in a form satisfactory to the Department, executed by the person who designed and supervised the installation of the cathodic protection system, setting forth the type of cathodic protection system installed, a description of the system and its location, the date of final inspection of the installed system, and such person's certification that the system has been installed and is functioning properly and that the system is designed to provide corrosion protection for at least 30 years.
(d) Coatings. Coatings steel underground storage tanks and piping at motor fuel-dispensing facilities shall be designed and installed in compliance with the following requirements:
(1) Types of coatings. Steel tanks shall be factory-coated with a dielectric material acceptable to the Department. The coating's coefficient of thermal expansion must be compatible with steel so that stresses due to temperature changes do not affect the soundness of the coating and the permanent bond which exists between the coating and the steel. The coating must be of sufficient density and strength so that it will not crack, wear, soften or disbond under normal service conditions. The coating must be stable under adverse underground electrolytic conditions and shall be chemically resistant to the products stored. The coating shall have been factory inspected for air pockets, cracks, blisters and electrically tested with a holiday detector at a minimum of 10,000 volts for coating defects such as pinholes.
(2) Site inspection. All coated tanks shall be inspected on site for coating defects prior to installation. An affidavit attesting to the integrity of the tank coating shall be submitted by a certificate of license holder upon the request of the Department.
(e) Dispensers and Pumps. Upon completion of the installation of a motor fuel dispenser or motor fuel-dispensing pump, such dispenser and pump shall be tested for proper operation by a certificate of license holder. All readily accessible piping shall be inspected for any evidence of leaks. An affidavit executed by such installer attesting to compliance with this requirement shall be submitted to the Bulk Fuel Unit of the Bureau of Fire Prevention.
