OPINION
Appellant challenges revocation of his driver’s license on the ground that the breath test results from the Intoxilyzer 5000 were not entitled to a presumption of accuracy when the machine, without explanation, printed the wrong date. Because the Commissioner of Public Safety established that the normal testing standards critical for accurate determination of alcohol concentration had been met and that appellant’s alcohol concentration exceeded that permitted for drivers of vehicles, appellant had the burden of coming forward with evidence that the date error indicated machine malfunction that affected the validity of the resulting alcohol concentration. Because appellant introduced no such evidence, we affirm.
. FACTS
Appellant Mark Allen Kramer challenges the district court’s revocation of his driver’s license under the Implied Consent Law, Minn.Stat. §§ 169A.50-.53 (2004). Appellant was arrested for DWI on September 6, 2004, and submitted to an Intox-ilyzer 5000 breath test. Deputy Daniel Robert Snow, a Carver County detention deputy and certified Intoxilyzer operator, conducted appellant’s breath test. The In-toxilyzer report showed that appellant’s alcohol concentration was .12, which resulted in his license revocation.
At the implied consent hearing, Snow testified that before he administered the Intoxilyzer test he checked the appellant’s
Snow further testified that, a week after administering the test, he realized that the date printed on the Intoxilyzer report was incorrect. All other relevant information, however, including the time of the test, was correct. At his supervisor’s direction, Snow prepared a supplemental report stating that the correct test date was September 6, 2004, the date of appellant’s arrest, not September 16, 2004, the date reflected on the report print-out. Appellant did not object when the Intoxilyzer report was admitted into evidence. However, appellant contended that because the commissioner did not establish that the date error did not affect the measuring functions of the Intoxilyzer, the test results were not prima facie reliable and should be rejected. The district court rejected appellant’s argument. This appeal followed.
ISSUE
Was it error for the district court to place the burden on appellant to establish that the wrong date in the printed results from the Intoxilyzer compromised the otherwise admissible results of that machine’s test of appellant’s breath?
ANALYSIS
The material facts of this case are not in dispute. Rather, appellant asserts that the district court erred, as a matter of law, by concluding that the In-toxilyzer report that is the basis for his conviction is prima facie reliable. While a district court’s findings of fact will not be set aside unless clearly erroneous,
Schultz v. Comm’r of Pub. Safety,
Because proceedings under the Implied Consent Law are civil in nature, the commissioner need only demonstrate that revocation of driving privileges was appropriate by a preponderance of the evidence.
Liona v. Comm’r of Pub. Safety,
Prima Facie Requirements
The commissioner meets his burden by demonstrating that a certified Intoxilyzer operator administered the test, and that diagnostic checks showed that the Intoxilyzer machine was in working order and the chemicals used were in proper condition.
Zern v. Comm’r of Pub. Safety,
In this case, appellant acknowledges that the Intoxilyzer report is from his September 6, 2004, arrest, and did not question Snow’s capabilities as a certified In-toxilyzer operator. Moreover, appellant does not challenge that Snow conducted air-blank checks, or that the chemical levels were within the expected ranges. Therefore, the evidence submitted by respondent establishes a prima facie case under current standards.
See Zem,
However, appellant confuses respondent’s requirement to present a prima facie case with appellant’s burden to refute that pri-ma facie showing.
Refuting Prima Facie Case
“Once a prima facie showing of trustworthy administration has occurred, it is incumbent upon defendant to suggest a reason why the ... test was untrustworthy.”
Tate,
The driver may challenge the sufficiency of the prima facie case in a number of ways. For example, “the defense is free to argue the possibility of contamination or other irregularity in the taking of a blood alcohol sample,”
id.,
or the driver may allege that the Intoxilyzer gave a false reading because of a low chemical level. However, merely alleging that the chemical testing solution was low does not automatically render the test unreliable.
Johnson v. Comm’r of Pub. Safety,
The driver may also assert that the statutory requirements were not met. In
Olson v. Comm’r of Pub. Safety,
the
Establishing that some impropriety or irregularity occurred during the observation period which would render the test result invalid is also a proper basis for challenging the test’s reliability. The observation period is recommended by the Bureau of Criminal Apprehension (BCA) as a means to ensure that the Intoxilyzer test results are accurate.
Nelson,
If the certified Intoxilyzer operator does not personally conduct the pretest observation period, yet testifies to the test’s reliability, the driver may refute that showing with evidence that the officer who did conduct the observation did so in a faulty manner. Also, if the observing officer is not trained in pre-test observation, and testifies that she did not understand the purpose of the observation period, the commissioner’s prima facie case of reliability is refuted.
McGregor v. Comm’r of Pub. Safety,
Thus, there exist myriad ways for the driver to challenge the revocation of his driver’s license under the Implied Consent Law. However, arguing that something
might
have occurred is mere speculation and insufficient unless supported by additional evidence.
Falaas,
In this case, appellant does not contend that a faulty observation period, invalid testing procedures, or improper diagnostic checks produced an unreliable Intoxilyzer report. He only observed that the date “September 16, 2004,” instead of “September 6, 2004,” appears at the top of the Intoxilyzer report. Appellant did not present any evidence that such a misprint was an indication that the testing mechanism was not working properly, nor did appellant present evidence controverting Snow’s testimony that in his opinion, as a certified Intoxilyzer operator, the machine was in working order. Appellant simply asserts that the misprinted date is indicative of a larger problem that so undermines the validity and trustworthiness of the Intoxilyzer report as to negate its prima facie status. This is not enough.
DECISION
We conclude that the district court properly determined that respondent presented a prima facie case and that appellant failed
Affirmed.
