(A) Upon receipt of any underground storage tank at the site, and prior to lifting the tank into the tank excavation, each tank shall be soap tested in accordance with Section 2-7 of the Flammable and Combustible Liquids Code, adopted by the National Fire Protection Association (NFPA 30).
(B) After installation of the underground storage tank into the tank excavation and before being completely covered, each tank shall be air tested with a gauge pressure not to exceed five pounds per square inch. Product piping shall also be tested, but with a minimum gauge pressure of 30 pounds per square inch. Any primary piping shall be tested at a minimum gauge pressure of 30 pounds per square inch. Any secondary or tertiary containment piping shall be tested at a minimum gauge pressure of five pounds per square inch. If the underground tank meets the requirements of the air test then the tank shall be ballasted with water or fuel until placed into service.
(C) Manual monitoring of secondary and tertiary containment shall begin when tanks are ballasted. Continuous monitoring shall begin when tanks are placed in service. Results of all monitoring prior to placing tanks in service shall be submitted to the city before or during final inspection. A precision test may be used in lieu of manual monitoring, if accomplished before the tanks are placed into service.
(D) The owner of the tank may elect to not ballast underground storage tanks with water upon installation if the tank is air tested when installed and backfilled, and, prior to being placed into service, the tank is tested in the operating condition using the precision test defined by the National Fire Protection Association Pamphlet 329, "Recommended Practices for Handling Underground Leakage of Flammable Combustible Liquids," as amended, for proving the integrity of an underground storage tank.
