PERMANENT RULES
Date of Adoption: August 2, 2001.
Purpose: Amendments to rules to clarify intent in the areas of acceptable use of the external standard simulator thermometer, acceptable range for the external standard simulator result, severability, and the need to repeat the fifteen minute observation period following an invalid sample.
Citation of Existing Rules Affected by this Order: Amending WAC 448-13-040 and 448-13-060.
Statutory Authority for Adoption: RCW 46.61.506.
Adopted under notice filed as WSR 01-11-134 on May 23, 2001.
Changes Other than Editing from Proposed to Adopted Version: The following additional comments regarding the amendments and proposed new sections were received and considered; however, no changes to the proposed version have been made.
Two written comments were received regarding the adoption of this permanent rule, and oral comment was also taken at a hearing in Bellevue, Washington on June 26, 2001. The issues raised were considered, and consideration and response is given in this concise explanatory statement.
Why was the acceptable range for the thermometer reading not changed to 34 degrees plus or minus 0.1 degrees instead of 0.3 degrees? This question reflects a misunderstanding of the issue ruled on by judges in Renton and Bellevue district courts in King County. These courts found that there was no explicit recognition in the WAC of the limits of accuracy of the mercury in glass thermometers used in the breath test equipment, and that thus, any variability in the thermometer must be included within the acceptable range. By enlarging the acceptable range to 0.3 degrees centigrade, but continuing to require a thermometer reading of 34 degrees plus or minus 0.2 degrees in the operation of the program, the potential variance in the thermometer is explicitly recognized and allowed for. Changing this allowable range does not introduce any additional inaccuracy into the measurement of the subject's breath alcohol concentration.
Does this change in the allowable range introduce a more lax standard for the breath alcohol test? No, the limited accuracy of the thermometer and its potential to lose accuracy over time has not been demonstrated to introduce additional error into the subject's breath test. As such, maintaining the established practice for conducting the breath test, but adjusting the acceptable range to address the courts concerns with respect to admissibility, ensures continuity of accuracy and reliability in the test.
Does the lack of a savings clause create a problem for cases occurring prior to the change to the 0.08 simulator standard in 1999? The WAC change as published (WSR 01-11-134) does include a savings clause (see WAC 448-13-060(5)), which explicitly states that the validity of the test is determined with respect to the provisions in place at the time the test was administered. This is consistent with rulings from municipal and county courts of limited jurisdiction in 1999, which found that validity of the test would be determined with respect to the WAC in effect at the time.
There is no explicit definition of accuracy for the thermometer in the definitions section. The standard dictionary definition adequately conveys the meaning this term for the purpose of the WAC.
Is the thermometer certification protocol based on NIST standards? No, however, it is a reasonable protocol based on the design of the thermometer. There is no NIST protocol for certifying this custom thermometer. NIST recommends testing of thermometers at multiple temperatures, which is done during calibration at the time of manufacture. This is not an attempt to evaluate the actual variance for that thermometer, but simply a check to see if they meet a specified minimum standard for certification. Given that there is no demonstrated effect of the accuracy of this thermometer on the results of the subject's breath test, this is a reasonable standard.
Is the state toxicologist going beyond his statutory authority in adopting the WAC regarding the admissibility of the test? The administrative code provisions in chapter 448-13 WAC are simply setting out which elements are needed for a reliable and accurate test. The WAC does not mention admissibility, which is a determination made by the court. The state toxicologist is however concerned that the scientific standards of the test meet the court's threshold for admissibility.
There is no definition of the term "certified" with respect to the thermometer. Directions with respect to the certification of the thermometer are maintained in the policy and procedures manual of the Washington State Patrol Breath Test Section, and are available on request. Technicians will prepare a declaration indicating the date of testing, the thermometer serial number, the simulator serial number, and the DataMaster instrument serial number, along with an indication of whether the thermometer met the specified standard described in WAC 448-13-035 in order to be certified.
The language used in WAC 448-13-035 referencing "standards traceable to NIST" is vague. The concept of traceability to a reference standard is a common principle in measurement science. It describes the notion that there is an absolute standard for temperature, maintained by the National Institute for Standards and Testing (NIST), and that the reference thermometer used to certify the mercury in glass thermometers used in this program, must be compared against a thermometer which has been checked either directly or indirectly against that absolute standard, and can thus be "traced" to it.
Is this an emergency, and is it valid to change the WAC for purposes of admissibility? The purpose of the hearing conducted in Bellevue on June 26, 2001, was to consider the proposed permanent changes to the administrative code, not the propriety of the emergency finding. The reasons for the state toxicologist's finding of an emergency were described in WSR 01-10-007. The use of an emergency WAC filing under RCW 34.05.350 in 1999, to address a similar situation in which breath tests were being suppressed was upheld by the Thurston County Superior Court, in an administrative procedures action brought in Gober v. Logan (Thurston County Superior Court Cause No. 00-2-00442-4). Any challenge to the agency's current finding of an emergency should be brought in the same venue.
Does approval of the use of the simulators with a plus or minus 0.3 degree acceptable range go beyond what is approved on the NHTSA conforming products list, and as such does this invalidate that approval? Neither the manufacturer's manual for the Guth 34C simulator, the conforming products list, or the NHTSA protocol for testing (62FR43416) reference any range of allowable operation for the simulator. Although the amended WAC allows a range of plus or minus 0.3 degrees, the protocols in place still require an observed range of plus or minus 0.2 degrees. The additional allowable tenth of a degree has been adopted to account for the limits of accuracy to which the thermometer can be certified, which is specifically stated in WAC 448-13-035 to be a tenth of a degree.
Does the simulator manufacturer require regular checking of the accuracy of the thermometer in their manual? The manufacturer (Guth Laboratories) does not recommend in their manual that the thermometer be checked for accuracy.
Should operators be required to record the actual temperature of the solution? The WAC has never required operators to record the actual temperature of the solution, and the training given to the operators has simply instructed them in how to determine if the displayed temperature fell within the allowable range of 34 degrees plus or minus 0.2 degrees centigrade. While it is important for the operators to be able to make this determination, the actual temperature within the range is not relevant in determining the accuracy of the test.

((The temperature of the solution in the simulator p)) Prior
to the start of the test ((must be)) the operator must verify
that the thermometer, certified per WAC 448-13-035, indicates
that the temperature of the simulator solution is thirty-four
degrees centigrade plus or minus ((0.2)) 0.3 degrees centigrade. During the test the person will be required to provide at least
two valid breath samples. A refusal to provide a valid breath
sample at any point during the test will constitute a refusal. The results of the test will be provided in the form of a
printout on a breath test document. These results will indicate
the grams of alcohol per two hundred ten liters of breath.

(1) The internal standard test results in the message "verified."
(2) In order to be valid, the two breath samples must agree to within plus or minus ten percent of their mean. This shall be determined as follows:
(a) The breath test results shall be reported, truncated to three decimal places.
(b) The mean of the two breath test results shall be calculated and rounded to four decimal places.
(c) The lower acceptable limit shall be determined by multiplying the above mean by 0.9, and truncating to three decimal places.
(d) The upper acceptable limit shall be determined by multiplying the mean by 1.1 and truncating to three decimal places.
(e) If the results fall within and inclusive of the upper and lower acceptable limits, the two breath samples are valid.
(3) The simulator external standard result must lie between
((.090 to .110 inclusive for tests conducted prior to April 1,
1999, and)) .072 to .088 inclusive ((for tests conducted on or
after April 1, 1999. This provision is remedial in nature and
applies to any judicial or administrative proceeding conducted
after April 27, 1999)).
(4) All four blank tests must give results of .000.
If these criteria are met, then these and no other factors are necessary to indicate the proper working order of the instrument, and so certify it, at the time of the breath test.
(5) These criteria have changed over time, and the criteria applied to determine the validity of any test and so certify it, should be those provisions of the Washington Administrative Code in effect at the time the test is administered.
