Exceptions will be made where the requirements of this subpart are met, that is, loading rack distance requirements to property lines and buildings, pump and daily gauging requirements, and the like, and a written approval has been issued based on proper application and drawings submitted for the use of the tank and related pumping equipment as a bulk plant.

 Pumps shall be of a fixed type substantially anchored or attached to a noncombustible base. Pumps shall be designed and equipped for use with flammable or combustible liquids and constructed so that no part of the system will be subjected to pressures above its allowable working pressure. Pumps, except those of submergible design, installed outside of buildings, shall be located not less than 10 feet from lines of adjoining property and not less than 5 feet from any building opening. Pumps shall be protected against physical damage. Exception: Pumps, which are an integral part of a tank vehicle which is operated and maintained in accordance with 67 Pa. Code Chapter 403 (relating to hazardous substances), may be used for handling crude oil in crude-producing areas where electrical power is impracticable and under emergency conditions such as leaking tanks, or for tank maintenance purposes. These pumps shall be provided with automatic means to prevent pressure in excess of the design working pressure of the accessories, piping and hose.

 Construction of protective enclosures for pumping equipment shall be of noncombustible materials throughout and, adequate ventilation shall be provided for such enclosures to prevent the accumulation of flammable vapors in hazardous concentrations. Design of ventilation systems shall take into account the relatively high specific gravity of the vapors. Ventilation may be provided by adequate openings in outside walls at floor level, unobstructed except by louvers or coarse screens. When natural ventilation is impracticable, mechanical ventilation shall be provided. Mechanical systems for removing flammable vapors shall be designed, installed, and operated in accordance with approved standards.

 Construction, exits, heating, ventilation and fire control of buildings housing pumping equipment shall be in accordance with the requirements of the Fire and Panic Act, except in cities of the Second Class A.

 (b)  Dispensing devices used with a vapor processing system shall be approved. Existing listed or labeled dispensing devices may be modified for use with vapor processing systems provided they are ‘‘Listed by Report’’ as specified in §  13.113a(b) (relating to vapor recovery system).

 (c)  Means shall be provided in the vapor return path from each dispensing outlet to prevent the discharge of vapors when the hose nozzle valve is in its normal nondispensing position.

 (d)  Vapor processing systems employing blower-assist shall not be used unless the system is designed to prevent flame propagation through system piping, processing equipment, and tanks.

 (e)  If a component is likely to contain a flammable vapor-air mixture under operating conditions, and can fail in a manner to ignite the mixture, it shall be designed to withstand an internal explosion without failure to the outside.

 (f)  Vapor processing equipment shall be located outside of buildings at least ten feet from adjacent property lines which can be built upon, except as provided for in subsection (g). Vapor processing equipment shall be located a minimum of 20 feet from dispensing devices. Processing equipment shall be protected against physical damage by the provision of guard rails, curbs, or fencing.

Such means may include protective enclosures which extend at least 18 inches above the equipment, constructed of fire resistant or noncombustible materials, installation in below-grade spaces, or protection with an approved water spray system. If protective enclosures or below-grade spaces are used, positive means shall be provided to ventilate the volume within the enclosure to prevent pocketing of flammable vapors. In no case shall vapor processing equipment so protected be located within 5 feet of adjacent property lines which can be built upon.

 (h)  Electrical equipment shall be in accordance with the National Electrical Code.

Shelter for pumps or loading personnel may be part of the loading rack. Loading racks shall be designed and equipped for the specific purpose of handling flammable or combustible liquids so that no part of the loading rack system will be subjected to pressures or circumstances beyond its designed use or capabilities.

   (2)  Static protection. Racks dispensing class I liquids into open domes of tank vehicles, and racks dispensing class II or class III liquids into open domes of tank vehicles which may contain flammable vapors from previous cargoes of class I liquids shall be equipped with protection against static sparks during tank vehicle filling. Protection shall consist of a metallic bond-wire permanently electrically connected to the fill-stem or some part of the fill-stem piping.

 (b)  Tank car racks. Class I liquids shall not be discharged from nor loaded into tank cars unless protection against stray currents has been provided and is used. Protection shall be designed and installed in accordance with Static Electricity, NFPA No. 77. The fire marshal may require tank cars to be unloaded through the dome or top outlet if escaping liquid would gain access to waterways, sewage systems, or endanger surrounding property.

 (c)  Container filling facilities. Class I liquids shall not be run into containers unless the nozzle and container are electrically interconnected. There shall be compliance with the provisions of this subsection if the metallic floorplate on which the container stands while filling is electrically connected to the fill stem, or where the fill stem is bonded to the container during filling operations by means of a bond-wire.

 (d)  Drainage and waste disposal.
