SPS 340.43(1)(1) Public self-service prohibited. Self-service dispensing by the general public of any gas regulated by this chapter is prohibited, except trained members of the general public may fuel compressed natural gas motor vehicles through a fueling connection that complies with ANSI NGV1–2006. SPS 340.43 NoteNote: The ANSI NGV1–2006 standard contains construction and performance criteria for compressed natural gas vehicle fueling connection devices consisting of (1) a receptacle (mounted on the vehicle), (2) a nozzle (mounted on fueling dispenser), and/or (3) a three-way valve (internal or external to the nozzle), having design pressures of 2400, 3000 or 3600 psig. Nozzle design will not permit gas flow until positively engaged to the receptacle and will not release the receptacle until gas flow has ceased and captured gas is safely vented. Intermating components are standardized. Nozzle and receptacle design prevent the fueling of a vehicle with lower service pressure by a dispenser with a higher service pressure.
SPS 340.43(2)(2) General. No person, except for the following, may dispense any gas regulated by this chapter unless the dispensing is through approved dispensing devices: SPS 340.43(2)(a)(a) A trained and authorized employee of a bulk storage plant, container charging plant or service station. SPS 340.43(2)(b)(b) A trained and authorized employee of an entity operating a commercial fleet of motor vehicles. SPS 340.43(3)(3) Location of key-, card- or code-operated dispensing systems.
