(2) The director or the director's authorized agent shall have access during normal business hours to all places where motor vehicle fuel is sold to or by a retail dealer, nonretail dealer or wholesale dealer for the purpose of examination, inspection and investigation of the establishment's motor vehicle fuel supply, shall collect or cause to be collected samples of the motor vehicle fuel and shall test or analyze the samples for compliance with motor vehicle fuel quality standards adopted pursuant to ORS 646.957.

(3) Before taking any enforcement action under ORS 646.953 or 646.963, the director shall cause motor vehicle fuel samples to be tested in accordance with standards, reproducibility limits and procedures that are, in the director's judgment, consistent with ASTM International standards and procedures.

The volume of the sample taken for testing must be adequate for the tests to be performed and to allow for a portion of the sample to be retained for subsequent testing, if the need arises. A sample with a test result that is outside the test reproducibility limits, when compared to the applicable limits, shall be properly stored to preserve the sample for at least 90 days.
