Cal. Health & Safety Code § 46072

In any case where any state agency is carrying out or sponsoring any activity resulting in noise which the director determines amounts to a public nuisance or is otherwise objectionable, such agency shall consult with the director to determine possible means of abating such noise. This section does not apply to any action of a private person for which a license, permit, or other entitlement for use is required to be issued by a state agency.
