California Code, Public Resources Code - PRC § 29770

(a) Any person who is aggrieved by any action taken by a local government or other local agency in implementing the resource management plan, or otherwise taken pursuant to this division, may file an appeal with the commission.  The ground for an appeal and the commission consideration of an appeal shall be that an action, as to land located exclusively within the primary zone, is inconsistent with the resource management plan, the approved portions of local government general plans that implement the resource management plan, or this division.  The appeal shall be heard by the commission within 60 days from the date of the filing of the appeal, unless the commission, either itself or by delegation to the executive director, determines that the issue raised on appeal is not within the commission's jurisdiction or does not raise an appealable issue.

(b) In the absence of an appeal by an aggrieved person, the commission may decide by majority vote to review on appeal any action taken by a local government or other local agency in implementing the resource management plan, or otherwise taken pursuant to this division, for land located exclusively within the primary zone, if the commission believes the action may be inconsistent with the resource management plan, or this division.

(c) The commission shall, by regulation, adopt administrative procedures governing those appeals.

(d) The commission may comment on projects within the secondary zone that impact the primary zone.
