1. (a) After the manufacture of or the conversion to a CNG system on any vehicle to be used as a school bus, mass transit, public transportation, or special transit vehicle, the manufacturer, licensee, or ultimate consumer making the installation or conversion shall notify LP-Gas Operations in writing on CNG Form 1503 that the applicable CNG-powered vehicles are ready for a complete inspection to determine compliance with the rules in this chapter.
2. (b) If LP-Gas Operations' initial complete inspection finds the vehicle in compliance with the rules in this chapter and the statutes, the vehicle may be placed into CNG service. For fleet installations of identical design, an initial inspection shall be conducted prior to the operation of the first vehicle, and subsequent vehicles of the same design may be placed into service without prior inspections. Subsequent inspections shall be conducted within a reasonable time frame to ensure the vehicles are operating in compliance with the rules in this chapter. If violations exist at the time of the initial complete inspection, the vehicle shall not be placed into CNG service and the manufacturer, licensee, or ultimate consumer making the installation or conversion shall correct the violations. The manufacturer, licensee, or ultimate consumer shall file with LP-Gas Operations documentation demonstrating compliance with the rules in this chapter, or LP-Gas Operations shall conduct another complete inspection before the vehicle may be placed into CNG service.
3. (c) The manufacturer, licensee, or ultimate consumer making the installation or conversion shall be responsible for compliance with the rules in this chapter, statutes, and any other local, state, or federal requirements.
4. (d) If the requested LP-Gas Operations inspection identifies violations requiring modifications by the manufacturer, licensee, or ultimate consumer, LP-Gas Operations shall consider the assessment of an inspection fee to cover the costs associated with any additional inspection, including mileage and per diem rates set by the legislature.
