California Code, Public Resources Code - PRC § 777

(a) If the board finds against the registrant, the board, in its decision, may terminate all operations of the registrant during the period fixed by the decision, except those operations the board determines that the person may complete.  The board may impose upon the registrant compliance with specific conditions as may be just in connection with the registrant's operations, and may further provide that, until the conditions are complied with, no application for restoration of the suspended or revoked registration shall be accepted by the board.

(b) The board shall provide public notice of the suspension or revocation pursuant to this section.

(c) The board may issue a private reprimand when a registrant commits a failure of responsibility that warrants a lesser level of discipline than suspension.  The issuance of a private reprimand does not prohibit the board from using the subject of the private reprimand in an accusation, within the statute of limitations, seeking suspension or revocation resulting from a subsequent complaint, to establish a pattern of lesser failures of professional responsibility.  If the evidence is insufficient to support a private reprimand or an accusation, the executive officer for registration may send a letter expressing the examining committee's concerns.
