Dear PEI Member:
The technical committees responsible for drafting the Code for Motor Fuel Dispensing Facilities and Repair Garages (NFPA 30A) and the Flammable and Combustible Liquids Code (NFPA 30) have issued first draft reports in response to changes suggested by the public. Both committees are now accepting comments to their draft reports through May 16, 2016. There are over 40 amendments to the codes in all, and six changes that could impact PEI members and their customers in jurisdictions that follow these codes. All six are located in NFPA 30A.
On-demand fueling services (Section 9.6) were discussed in detail in the February 3, 2016, TulsaLetter. Although the technical committee voted to allow this new practice of providing on-demand fueling services by a 20-2 vote, it’s our sense that the committee was very interested to hear more input from the regulated community on this potentially controversial topic.
Double-poppet shear valves (Section 6.3.9) would be required on all new installations in which a pressure system is utilized. The committee agreed with a public comment that a double-poppet shear valve provides an additional level of protection against fire because it retains liquid on both sides of the shear point of the valve.
The committee agreed that line leak detectors used on submersible pumps are not capable of sounding an audible or visual alarm as currently required by Section 6.4.2 of NFPA 30A. The relevant sentence of Section 6.4.2 would read as follows if the change suggested by the committee is made: “Each pump shall have installed on the discharge side a leak detection device that will provide an audible or visible indication restricts or shuts off the flow of product if the piping or a dispenser is leaking.”

The technical committee determined that emergency shutoff devices need to control other systems commonly installed at fuel islands, including vacuums, windshield washing fluid dispensing systems, and compressed air supplies. The committee recommends that the following sentence in Section 6.7 of NFPA 30A be expanded to isolate that equipment: “Emergency shutoff devices or electrical disconnects shall disconnect power to all dispensing devices; to all remote pumps serving the dispensing devices; to all associated power, control, and signal circuits; and to all other electrical equipment in the hazardous (classified) locations surrounding the fuel island; and shall mechanically or electrically isolate other fluid transfer systems serving the fuel dispensing area.”
Concern was expressed to the committee that material such as wood, bagged ground cover, cartons of consumable products and other combustibles displayed near the fuel dispenser could obstruct the view of the attendant and/or consumer and would constitute a fuel load that should not be in the area of the fuel dispenser. To address these issues, the committee proposes to add a new Section 220.127.116.11 governing display of materials to read: “The storage or placement for display or sale of products shall be prohibited within 20 feet of any fuel dispenser.”
The committee recognized that the development of system components for alternative fuels like CNG, LNG, hydrogen and LP-Gas is proceeding concurrently with the development of listing standards. Accordingly, the committee proposed to change Section 12.2.3 governing those devices by requiring them to be listed or approved. This change would give the authority having jurisdiction more flexibility in evaluating the equipment involved in new installations.
