Compressed Natural Gas (CNG) motor vehicle fuel-dispensing equipment installation requirements are outlined in 2021 International Fire Code (IFC) Section 2208 - Compressed Natural Gas Motor Fuel- Dispensing Facilities.
IFC 2021, Section 2208.3 - Equipment Location and Protection:
Requires that CNG dispensing equipment be installed at least:
10 feet from property lines
20 feet from public streets, highways, sidewalks, or railroads
10 feet from buildings or structures
Why Other Options Are Incorrect?
A: 40 ft. from trolley wires.
The IFC does not specify a 40-ft requirement for trolley wires in relation to CNG fuel-dispensing equipment.
B: 15 ft. from a public street.
Incorrect because IFC 2208.3 states that the minimum required distance from a public street is 20 feet, not 15 feet.
D: 5 ft. from an undeveloped property line.
Incorrect, as the minimum clearance from any property line is 10 feet, not 5 feet.
