(1) all equipment subject to inspection and testing requirements must be inspected and
tested annually;
(2) inspection testing must only be done by persons who have demonstrated to the director
that they are competent to inspect and test liquefied petroleum gas-measuring equipment.
Competency may be established by passage of a competency examination, which the director
