(1) Any inspector of the bureau is authorized to enter any premises where units are manufactured, whether or not requested by the manufacturer. He may inspect and examine any plans, specifications, in-plant quality control procedures, third party agency procedures, units and unit equipment and installations to ensure compliance with the provisions of these rules. When it becomes necessary to determine compliance, the inspector may require that a portion or portions of such units be removed or exposed in order that any inspection may be made. Manufacturers in nonreciprocal states may be subject to at least one in-plant inspection per year, by the bureau, for which the inspection fees in ARM 24.301.565 through 24.301.567 will be charged.
