Cal. Health & Safety Code § 25187.6

(a) If an authorized agent of the department has probable cause to believe that any hazardous waste, or any material which the authorized agent reasonably believes to be a hazardous waste, is stored, transported, disposed of, or handled in violation of this chapter or in a manner that will constitute a violation of this chapter, and that the violation may threaten public health and safety, or the environment, the agent may issue an order of quarantine by affixing a tag or other appropriate marking to the container containing, or to the vehicle transporting, the hazardous waste.
(b) Upon issuing an order of quarantine pursuant to subdivision (a), the authorized agent shall notify the person who owns the hazardous waste, or the owner or lessee of the vehicle in which the wastes are transported, of all of the following:
1. (1) The hazardous waste has been subject to a quarantine order because the hazardous waste is, or is suspected of being, stored, transported, disposed of, or handled in violation of this chapter.
2. (2) No person shall remove, transfer, or dispose of the hazardous waste until permission for removal, transfer, or disposal is given by an authorized agent of the department or by a court.
3. (3) The person so notified may request, and shall be granted, an immediate hearing before a person designated by the director to review the validity of the authorized agent’s order. For purposes of this section, an immediate hearing shall be held within 24 hours after a hearing is requested by the person subject to the order.
(c) Any order of quarantine issued pursuant to subdivision (a) shall take effect upon issuance and shall remain effective for 30 days thereafter, until an authorized agent removes the quarantine order pursuant to subdivision (d), or until the quarantine order is revoked pursuant to a hearing conducted in accordance with paragraph (3) of subdivision (b), whichever event occurs first.
(d) If an authorized agent of the department determines that a hazardous waste subject to a quarantine order is not being stored, handled, transported, or disposed of in violation of this chapter, or does not threaten public health and safety or the environment, the authorized agent shall revoke the order of quarantine.
(e) If an authorized agent of the department has probable cause to believe that a hazardous waste subject to a quarantine order will, or is likely to, be removed, transferred or disposed of in violation of this section, the authorized agent may remove the hazardous waste to a place of safekeeping.
(f) A hazardous waste in transit for which a quarantine order has been issued pursuant to subdivision (a) shall be stored or held at one of the following locations, which the authorized agent determines will represent the least risk to the public health and safety or the environment:
1. (1) The facility owned or operated by the producer of the waste, except when the producer is located outside the state.
2. (2) The transporter’s yard, facility, or terminal.
3. (3) The treatment, storage, or disposal facility to which the hazardous waste is to be transported.
4. (4) Any other site designated by the authorized agent.
(g) All fees for storage and any other expenses incurred in carrying out subdivision (e) or (f) shall be a charge against the person who owns the hazardous waste or the owner or lessee of the vehicle in which the wastes are transported.
(h) For purposes of this section, “authorized agent of the department” includes any representative of a local officer or agency authorized to enforce this chapter pursuant to subdivision (a) of Section 25180.
