Whenever any application for development is approved subject to specified conditions intended to be fulfilled before the approval becomes effective, the conditional approval shall lapse and become null and void unless all specified conditions, other than those conditions pertaining to other governmental approvals as indicated in N.J.S.A. 40:55D-22b, are fulfilled within 190 days of the date of conditional approval. The applicant may, for good cause shown, apply for, and the Board may grant, extensions of time within which such conditions must be fulfilled as the Board may deem appropriate under the circumstances. Applications for such extension must be made prior to the expiration of the period within which conditions were previously required to be fulfilled.
