(c)(1) If the director determines at any time that the project is no longer consistent with subdivision (c) of Section 1652 or subdivision (b) of Section 1653, as applicable, due to a material change between the project as submitted and the project being implemented or a change in the environmental circumstances in the area of implementation, the director shall notify the project proponent in writing and project implementation shall be suspended. Written notice from the director shall be delivered in person, by certified mail, or by electronic communication to the project proponent and shall specify the reasons why approval of the project was suspended.

(2) Within 30 days of receipt of a notice of suspension, the project proponent may file an objection with the director. Any objection shall be in writing and state the reasons why the project proponent objects to the suspension. The project proponent may provide additional environmental protection measures, design modifications, or other evidence that the project is consistent with subdivision (c) of Section 1652 or subdivision (b) of Section 1653, as applicable, and request that the notice of suspension be lifted and approval granted.

(3) The director shall revoke approval or lift the suspension of project approval within 30 days after receiving the project proponent's objection pursuant to paragraph (2).
