Chevron U.S.A., Inc. v. County of MontereyAnnotate this Case
In this challenge to "Measure Z," a Monterey County ordinance, the Supreme Court affirmed the decision of the court of appeal affirming the judgment of the trial court in favor of Plaintiffs on preemption grounds, holding that Cal. Pub. Res. Code 3106 preempts Measure Z.
Plaintiffs - Chevron U.S.A. Inc. and other oil producers and mineral rights holders - brought six actions against the County challenging Measure Z, a local ordinance banning oil and gas wastewater injection and impoundment and the drilling of new oil and gas wells in the County's unincorporated areas. The trial court issued a writ of mandate directing the County to invalidate two prohibitions in the measure that applied to the County's unincorporated areas. The court of appeal affirmed on grounds of state preemption. The Supreme Court affirmed, holding that Measure Z contradicts, and therefore conflicts with and is preempted by, section 3106.
