Section 3821

(a) Upon receipt and deposit of revenues in the Geothermal Resources Development Account, 40 percent of the revenues derived from the sale of a lease, and any bonus paid in connection therewith, shall be immediately disbursed by the State Controller to the county of origin; and 40 percent of the revenues consisting of royalties and rents shall be immediately disbursed to all counties of origin in proportion to the amounts of the revenues derived from existing leases within each county of origin. If a lease includes land in more than one county, each county’s share shall be computed on the basis of the ratio that the acreage within each county bears to the total acreage in the lease.

(b) Each county of origin shall establish for deposit of such revenues an account or fund separate from the other accounts and funds of the county, and may expend such revenues only for the purposes specified in this chapter.
