Which organization develops the codes — particularly NFPA 52 — that most US states adopt for CNG fueling station regulation?
Answer: NFPA (National Fire Protection Association)
The National Fire Protection Association develops NFPA 52, which most US states adopt by reference as the governing code for CNG fueling stations.
What pricing information must a CNG dispenser display to customers at the point of sale in the US?
Answer: Price per GGE (gasoline gallon equivalent)
CNG dispensers must display the price per GGE (gasoline gallon equivalent) so customers can compare CNG costs directly with conventional liquid fuel prices.
How is CNG typically measured and sold at US retail fueling stations?
Answer: In GGE (gasoline gallon equivalents)
CNG is sold in GGE in the US, where 1 GGE equals approximately 126.67 standard cubic feet of natural gas, allowing direct energy comparison with gasoline.
What inspection requirement typically applies to high-pressure CNG storage cylinders at a fueling station?
Answer: Visual inspection plus periodic testing per manufacturer specifications and applicable codes
CNG storage cylinders require regular visual inspection and periodic testing (hydrostatic or other approved methods) at intervals specified by the manufacturer and applicable codes.
Before a CNG dispenser that failed a calibration check can return to commercial service, what must happen?
Answer: The dispenser must be recalibrated and re-certified by a weights and measures authority
Commercial fuel dispensers are regulated by weights and measures authorities; a failed dispenser must be recalibrated and officially re-certified before resuming sales.
What documents must be visibly posted at a CNG fueling station for customer access?
Answer: Emergency response plan and station permit with emergency contact information
CNG stations are required to post their operating permit and emergency contact information in a visible location accessible to customers and emergency responders.
Why does the GGE standard define 1 GGE as approximately 126.67 standard cubic feet (SCF) of natural gas?
Answer: To enable fair price comparison between CNG and gasoline based on equivalent energy content
The GGE converts CNG volume into an energy-equivalent unit equal to one gallon of gasoline, enabling transparent price comparison for consumers at the pump.
