If the Pinelands Commission disapproves an application for development previously approved by an approval agency, such approval shall be revoked within 30 days of the Commission's action by the approval agency and the agency shall thereafter deny approval of the application. If the Commission approves the decision of an approval agency subject to conditions, the approval agency which had previously approved the application shall, within 30 days, modify its approval to include all conditions imposed by the Commission; and if final approval of the application is required, shall grant final approval only if the application for approval demonstrates that the conditions specified by the Commission have been met by the applicant. Except as provided in subsection 26-65.10 (Procedures for Applications for the Development of a Single-Family Dwelling), the requirements of subsection 26-65.7 (Effects of Pinelands Commission's Decision on Borough Approval) shall not apply to the issuance of a preliminary zoning permit or a refusal to issue a preliminary zoning permit for the development of a single-family dwelling on an existing lot of record.
