Water use	not yet requested
No figure is on public record for this facility. Absence of a record here is a records gap, not a finding about the facility.

A county comparison puts it beside documented local withdrawals; a national total would make any single facility look small.

Permitting path

Approvals on record for 1 of 12 path steps.

California runs environmental review with the land-use entitlement: the lead agency for CEQA is usually the land-use authority, so the two milestones move together. Large onsite generation adds a California Energy Commission authorization.

Steps without a record are shown as not yet requested or not on record: absence of a record here is a records gap, not a finding about the facility. An authority shown for an empty step is the body that would issue it. Some authorities are shown before any record exists, from mapped utility service areas or, for sewer service, from municipal limits; these carry a marker naming the basis.
