(a) Resubmittal of a land use plan in response to the Commission's denial of certification shall cause the Commission's prior certification with suggested modifications to expire.

(b) If a local government elects to respond to the Commission's denial of certification by revising its land use plan in a manner other than that suggested by the Commission and resubmitting the revised land use plan to the Commission, preparation, submittal and review of the resubmitted land use plan shall take place in accordance with the provisions of Articles 7-12, except for the provisions related to time periods for hearings and action. Review of the resubmitted land use plan shall take place when the Commission determines that the land use plan can be reviewed without adversely affecting the review of other land use plans previously scheduled.

(c) Following a final decision on the land use plan, no local government may resubmit substantially the same land use plan for a period of six months from the date of the prior final decision. Whether or not a land use plan is “substantially the same” as that upon which a final decision has been rendered shall be decided by the executive director within ten (10) working days of receipt of the submittal. Elimination of suggested modifications shall not be considered a substantial change. Until such a determination is made a resubmittal shall not be deemed submitted within the meaning of Public Resources Code Section 30512. The six month waiting period provided in this section may be waived by the Commission for good cause.
