California Code, Public Resources Code - PRC § 71023

(a) The permit applicant may withdraw from the consolidated permit process by submitting to the consolidated permit agency a written request that the process be terminated. Upon receipt of the request, the consolidated permit agency shall notify the secretary and each participating permit agency that a consolidated permit is no longer applicable to the project.

(b) The permit applicant may submit a written request to the consolidated permit agency that the permit applicant wishes a participating permit agency to withdraw from participation on the basis of a reasonable belief that the issuance of the consolidated permit would be accelerated if the participating permit agency withdraws. In that event, the participating permit agency shall withdraw from participation if the consolidated permit agency approves the request.
