Cal. Health & Saf. Code § 25267
If, at any time after site investigation or remedial action at a hazardous materials release site has begun, the administering agency determines that the information concerning the site that was available at the time the administering agency was designated was not accurate or was incomplete and that new information would likely have resulted in the designation of a different administering agency, the administering agency may request the committee to review the original designation. If, after reviewing the new information and considering the factors and guidelines specified in subdivision (c) of Section 25262, the committee concludes that the original designation was not in the public interest, it may rescind the original designation and designate a different administering agency.
