A. Permit duration. Permits shall be valid for one year from the date issued. After said date, the permit will be void and a new permit must be obtained. If an extension is necessary to complete all work included under the permit, a request in writing must be made to the township.

B. Permit extensions. A permit may be renewed or extended for a period of time not to exceed the total time of the original permit, upon request of the permittee and upon payment of a new fee.

C. Permits issued under the provisions of this regulation are not transferable.

D. Revocation of pen-nits. Permits may also be revoked at any time if it is found by the township that the permittee has failed to comply with the provisions of this regulation or the permit, provided that written notice has been given to the permittee of such failure and that the permittee has failed to correct the defect. If, after permit revocation, it becomes necessary for the township to either complete the work or to refill and repair the opening, the cost of such work by the township will be recovered through the performance guaranty which was posted by the permittee.
