NFPA 30 & NFPA 30A Code Changes: Important Additions you Need to Know
NFPA 30 Amendments
The 2012 editions of NFPA 30 and NFPA 30A feature a number of changes which may be of interest to anyone involved with the storage and/or dispensing of fuel. A few important changes are highlighted below (selections from PEI Journal)
Any Class II or III liquid stored, handled or used above it’s flash point should be treated as a Class I Flammable Liquid – Chapter 6
Provisions were added to Chapter 6, Fire and Explosion Prevention and Risk Control, to require that any Class II or Class III liquid (liquids whose flash points are 100 °F or greater) stored, handled, or used at or above its flash point is to be treated as a Class I flammable liquid, unless an engineering evaluation deems otherwise. This recognizes the fact that a combustible liquid at or above its flash point presents the same risk of fire and explosion as a flammable liquid.
Interstitial space of a secondary containment-type tank is NOT required to have a normal vent – 21.4.3
Subsection 21.4.3, Normal Venting for Storage Tanks, an item was added to clarify that the interstitial space of a secondary containment-type tank is not required to have a normal vent. In the vast majority of cases, there is no liquid in that space that would cause pressure differentials to be relieved. Even if a breach of the primary tank were to release liquid into that space, any pressure difference can be relieved via the breach back into the primary tank.
Tightness test is NOT required for the interstitial space of a secondary containment-type tank – 21.5.2
The tank tightness testing provisions of Subsection 21.5.2 were amended to clarify that a tightness test is not required for the interstitial space of a secondary containment-type tank, if a factory-applied vacuum is maintained in that space. Almost all secondary containment- type tanks of double-walled design, both aboveground and underground, are shipped with a vacuum on the interstitial space. This provides continuous proof that both inner and outer walls of the tank are intact and not leaking so there is no need for a tightness test.
NFPA 30 Amendments
Fuel dispensing systems that are used for alcohol-blended fuels shall be listed or approved for the specific purpose – 6.2.3
“Fuel dispensing systems, including dispensers, hoses, nozzles, breakaway fittings, swivels, flexible connectors, dispenser emergency shutoff valves, vapor-recovery systems, and pumps that are used for alcohol-blended motor fuels shall be listed or approved for the specific purpose.” This was added to address those service stations that provide E85 fuel and the anticipated introduction of E15 into the existing retail infrastructure, with its existing dispensing systems.
Revised drawings depicting extent of hazardous locations for equipment that might be a source of ignitable vapors – Chapter 8
Chapter 8 was extensively revised to incorporate a reorganized table on area classification for determining the extent of hazardous (classified) locations associated with equipment that might be a source of ignitable vapors. This included the necessary criteria for the zone system of area classification, a revised drawing showing the extent of area classification around fuel dispensers, and a new diagram that depicts the extent of area classification around tank-mounted fuel dispensing units. (See below.)

Only The Best For New York’s Bravest
FDNY Fueling System (First UL2085 Gasoline System in NYC)
The FDNY is the largest municipal fire department in the United States. Their responsibilities include fire hazards, providing emergency medical services, technical rescue as well as providing first response to biological, chemical and radioactive hazards. FDNY Marine Battalion 6 required two new fueling systems to service their first response team. Core Engineered Solutions provided drawings, specifications, procurement manufacturing and installation assistance for both systems.
The facility design included an 8000 gallon ConVault (diesel) marina refueling system which services a number of boats including a converted Navy Destroyer (pictured above). In addition, the site required a 2000 gasoline system to refuel other land based emergency response vehicles. Core Engineered Solutions assisted in getting approval for the first UL2085 gasoline dispensing system in New York City. This fueling system consisted of a NYC approved ConVault AST.

Simplify Your Fuel System Installation with SafeSite: Fuel System Controls
SafeSiteTM Fuel System Controls are preengineered and install like a sub panel adjacent to your tank and dispensing area. Unlike other control systems the emergency stop breaks both power and neutral (per NEC code). They come delivered with your tank and include a site schematic showing conduit layout and specific point-to-point wiring diagrams for each component to help simplify installation and minimize on site expenses.
Single input power connection w/ dedicated outputs to:Features & Benefits Include:
- • Pumps
• Anti-syphon solenoid
• Fuel management (key/card)
• Tank gauging/monitoring
• Fire suppression
• Emergency stop (remote)
- Integrated power distribution and motor controls
- E Stop breaks both power AND neutral
- Panel mounted emergency stop controller (optional additional remote)
- Monitors / verifies integrity of emergency control circuit
- NEMA 4X enclosure (stainless steel available)
- Site specific conduit layout schematic
- Point-to-point wiring diagram specific to all industry pumps, dispensers, and other system components, including
• Gasboy / Dresser Wayne / Great Plains
• Red Jacket / FE Petro
• Veeder-Root / Pneumercator / Franklin / Omntec
