It shall be unlawful to transport or handle gasoline or other flammable liquid through pipes or other conduits of any kind from any unloading point as provided for above in Sec. 320 (2) to any storage tank or other container within the fire limits until after an applica- tion to pipe such flammable liquid has been finally approved by the City Manager, and no such final permit shall be issued until the following requirements have been complied with. (a) All applications for a permit shall be accompanied by complete plans and profiles of the proposed underground pipe systems. (b) Pipe shall be standard weight wrought iron or steel. (c) Except within eight feet from tank car and like distance from storage tank piping shall be buried a minimum depth of three feet and shall be laid below all other piping. Where pipe passes under railroad tricks it shall be laid at least four feet below the bottom of ties. (d) Piping shall rest on a solid earth foundation or shall be otherwise securely installed to minimize the possibility of undue stresses at joints from settling.

Where the elevation of the top of the storage tank is higher than that of the pump a check valve shall be placed in the discharge line to prevent the liquid from backing up into the tank car. Long pipe lines shall be provided with intermediate shut-off valves, the number depending on the length of the line. (i) Valves shall be set in manholes or have the valve stem extended to a valve box having a cover normally locked to prevent operation by unauthorized persons.

(j) Piping shall be tested after installation and before being covered, at a pressure of not less than 150 pounds per square inch, not less than 1-1/2 times the working pressure. Tests shall continue for at least 30 minutes without a noticeable drop in pressure.
