34 Pa. Code § 14a.33b. Fill- and return-piping.

§ 14a.33b. Fill- and return-piping.

(a)  A fill pipe shall terminate outside of a building at a point at least 2 feet from any building opening at the same or lower level. A fill pipe shall terminate in a manner designed to minimize spilling when the filling hose is disconnected. Fill opening shall be equipped with a tight metal cover designed to discourage tampering. Where a supply or storage tank has been removed from within a building, it shall be the responsibility of the owner of the tank to insure that the portion of the fill pipe system terminating outside the building is also removed at the same time to preclude the accidental use of the fill pipe which is no longer connected to the tank.
(b)  A return line from a burner or pump to a supply tank shall enter the top of the tank.
(c)  Cross connections, except between two supply tanks not exceeding 660 gallon aggregate capacity, permitting gravity flow from one tank to another shall be prohibited.
(d)  An auxiliary tank shall be filled by a pump transferring the oil through continuous piping from the supply tank.
(e)  An auxiliary tank shall be located at a level above the top of the supply tank from which it is filled.
(f)  An auxiliary tank shall be provided with an overflow pipe draining to the supply tank and extending into the top of the supply tank not more than one inch. This requirement shall not apply to an auxiliary tank specifically listed for use without an overflow pipe.
(g)  An overflow pipe from an auxiliary tank and a return line from a burner or pump shall have no valves or obstructions.
