In an action challenging the State Water Resources Control Board's approval of two amendments to the Water Quality Control Plan for the Sacramento River and San Joaquin River Basins, claiming that these amendments violate state and federal water law and CEQA, plaintiffs' petition for a writ of mandate is denied and the trial court's thorough and well-reasoned decision affirmed, including its denial of the petitions except for the issue of whether a substitute for the Salt/Boron total maximum daily loads (TMDL) was as effective as a TMDL.
