Pursuant to RCW 46.61.506, the state toxicologist will authorize the issuance to persons deemed qualified as "instructors," "operators," "solution changers" or "technicians," a permit bearing his or her name and designation. Permits will bear the signature or facsimile signature of the state toxicologist. Such permits will expire three years after the date on the permit, unless renewed for a like three-year period. Operators whose authorization expires may take recertification training within ninety days following expiration of their prior certification, but are not certified to perform any evidential breath tests during that period. Once ninety days have elapsed after the expiration of authorization, the operator must repeat the basic certification training.
