San Diego Gas & Electric Co. v. San Diego Regional Water etc.Annotate this Case
After years of investigation, the San Diego Regional Water Quality Control Board (Regional Board), issued a cleanup and abatement order (CAO) to San Diego Gas & Electric Company (SDG&E) and several other entities, in connection with a power plant’s operations that discharged waste into the San Diego Bay. The Regional Board found that SDG&E caused or permitted waste to be discharged into the Bay and thereby created, or threatened to create, pollution and nuisance conditions. SDG&E contested its designation as a responsible "person" under Water Code section 13304 (a), and petitioned for a writ of mandate to have the CAO vacated. The superior court denied the writ. SDG&E argued then, as it did before the Court of Appeal, that shipyard companies comparatively discharged greater amounts of pollutants into the Bay and that two appellate opinions required application of the "substantial factor" causation test to determine whether SDG&E created or threatened to create a condition of pollution or nuisance. The Court of Appeal found it was undisputed that SDG&E directly discharged and thus "caused or permitted" waste to enter the Bay, distinguishing the aforementioned appellate cases. Further, the Regional Board adequately demonstrated that the waste discharged by SDG&E created, or threatened to create, a condition of pollution or nuisance. Accordingly, the Court affirmed the judgment.
