Cal. Health & Safety Code § 118350
The enforcement agency may suspend, amend, or revoke any medical waste permit issued by the enforcement agency for any of the following reasons:
(e) The conviction of a permittee, or the person in charge of the activity subject to the medical waste permit, of any crime that is substantially related to the qualifications or duties of the permittee or the person in charge of the activity, or that is substantially related to the functions that are subject to the medical waste permit.
For purposes of this section, a conviction means a plea or verdict of guilty or a conviction following a plea of nolo contendere. An action to revoke or suspend the medical waste permit may be taken when the time for appeal has elapsed or the judgment of conviction has been affirmed on appeal. That action may also be taken when an order granting probation is made suspending the imposition of sentence, notwithstanding any subsequent order pursuant to Section 1203.4 of the Penal Code. The enforcement agency shall take into account all competent evidence of rehabilitation furnished by the permittee or person in charge of the permitted activity.
