Atlantic Richfield v. Central Valley Regional Water Quality etc.
Annotate this Case
Plaintiff Atlantic Richfield Company (ARCO) filed a petition in June 2014 to overturn a March 2014 order of defendant Central Valley Regional Water Quality Control District1 (Water Board) that sought to impose liability for remediation of metallic and acidic water pollution from an abandoned mine, the owner of which was the subsidiary of ARCO’s predecessors in interest. The trial court granted the petition in January 2018. The Water Board appealed, contending the trial court applied the wrong legal standard to determine whether the ARCO predecessors incurred direct liability for control over
activities resulting in the hazardous waste that the mine discharges. The Court of Appeal agreed the trial court employed too restrictive a standard in evaluating the evidence, and therefore reversed and remanded for reconsideration of the record under the proper standard.
