Roadside hydrogen service vehicles shall comply with the following:
- Roadside hydrogen service vehicles and hydrogen supply tanks shall comply with U.S. DOT requirements for the transportation of hydrogen gas.
- Individual hydrogen fuel supply tanks installed on roadside hydrogen service vehicles shall have a maximum individual fuel capacity of 1,270 cubic feet (3 kg) of hydrogen.
- The maximum aggregate amount of all hydrogen fuel in the supply tanks of roadside hydrogen service vehicles shall not exceed 4,233 cubic feet (10 kg) of hydrogen.
- The roadside hydrogen service vehicle shall comply with all local, state and federal requirements.
- The vehicle and its equipment shall be maintained in good repair.
The owner of a mobile hydrogen-fueling operation shall develop a written safety and emergency response plan that:
- Establishes policies and procedures for fire safety, hydrogen leak prevention and control, personnel training and compliance with other applicable requirements of this code; and
- Demonstrates readiness to respond to a hydrogen leak and carry out appropriate mitigation measures.
The owner of a mobile hydrogen-fueling operation shall develop a written fueling standard operating procedure (SOP) that:
- Clearly and unambiguously describes the sequence of steps that a roadside gaseous hydrogen service vehicle operator needs to take to ensure safety of gaseous hydrogen fueling and compliance with the fueling protocol requirements;
- Establishes a fueling protocol that is consistent with applicable requirements of a recognized national standard such as SAE J2601. Compliance with these requirements shall be demonstrated by a valid test record from an independent third party such as a recognized hydrogen-fueled vehicle OEM (Original Equipment Manufacturer).
