(a) In the event that the commissioner determines that action is necessary to prevent an imminent hazard during the time required for cancellation or change in classification proceedings or for the adoption of regulations, he may, by order, immediately suspend the registration or change the classification of the pesticide for some or all uses. No order of suspension may be issued unless the commissioner has issued or at the same time issues notice of his intention to cancel the registration or change the classification of the pesticide. Except as provided in subsection (c) of this section, the commissioner shall notify the registrant prior to issuing any suspension order. Such notice shall include findings pertaining to the question of imminent hazard. The registrant shall then have an opportunity, in accordance with the provisions of subsection (b) of this section, for an expedited hearing before the department on the question of whether an imminent hazard exists.

(b) If no written request for a hearing is received by the commissioner within five days of the registrant’s receipt of the notification provided for by subsection (a) of this section, the suspension order may be issued and shall take effect immediately. If a hearing is requested in writing, the hearing shall commence within five days after the receipt of the request for such hearing unless the registrant and the commissioner agree that it shall commence at a later time. The commissioner shall have fifteen days from the conclusion of the presentation of evidence to render a final order on the issue of suspension.

(c) Whenever the commissioner determines that an emergency exists that does not permit him to hold a hearing before suspending, he may issue a suspension order in advance of notification to the registrant. In that case, subsection (b) of this section shall apply except that the order of suspension shall be in effect pending the expeditious completion of the remedies provided by that subsection and the issuance of a final order on suspension, and no party other than the registrant and the department shall participate provided any person adversely affected may file briefs within the time allotted by the department rules.

(d) A final order on the question of suspension following a hearing shall be reviewable in accordance with chapter 54, notwithstanding the fact that any related cancellation proceedings have not been completed. Any order of suspension entered prior to a hearing before the commissioner shall be subject to immediate review in an action by the registrant or other interested person with the concurrence of the registrant in the superior court for the judicial district of Hartford, solely to determine whether the order of suspension was arbitrary, capricious or an abuse of discretion, or whether the order was issued in accordance with the procedures established by law. The effect of any order of the court shall be to stay the suspension order, pending the commissioner’s final decision with respect to cancellation or change in classification. This action may be maintained simultaneously with any other administrative review proceeding. The commencement of proceedings under this section shall not operate as a stay of order, unless ordered by the court.
