				  applicable diurnal or hot soak plus diurnal emission standard and the EMEL
				  declared for the model and is applicable to the entire evaporative family
				  represented by the model.
(13)
				  "Executive Order of Certification" means an order signed by the Executive
				  Officer that documents certification of evaporative emission control systems on
				  engines or equipment to the evaporative emission standards of this

				  fuel from the carburetor to the fuel tank that does not continuously contain
				  liquid fuel for handheld engines; and
(D) Primer bulbs that contain liquid fuel
				  only for priming the engine before starting.
(15) "Holder" means the person to whom the
				  Executive Order of Certification is issued.

				  procedures incorporated in this Article.
