Chevron U.S.A., Inc. v. County of MontereyAnnotate this Case
Ordinances banning “land uses in support of” new oil and gas wells and “land uses in support of” wastewater injection in unincorporated areas of Monterey County were enacted as part of Measure Z, an initiative sponsored by PMC and passed by Monterey County voters.
The trial court upheld, in part, a challenge to Measure Z by oil companies and other mineral rights holders. The court of appeal affirmed. Components of Measure Z are preempted by state laws. Public Resources Code section 3106 explicitly provides that the State of California’s oil and gas supervisor has the authority to decide whether to permit an oil and gas drilling operation to drill a new well or to utilize wastewater injection in its operations. Those operational aspects of oil drilling operations are committed by section 3106 to the state’s discretion and local regulation of these aspects would conflict with section 3106.
