Work for which a permit has been issued shall commence within ten days after the issuance of the permit therefor. If not so commenced, the permit shall be automatically terminated unless the permittee applies to the Service Director for an extension of time within which to commence work. If such an extension is granted, the original permit shall remain in force for the period of time specified in the extension. Permits which terminate within ten days after issuance or within any extension of time granted by the Director may be renewed only upon the payment of an additional permit fee as originally required.
