Terms of validity shall commence on the date Springfield Township signs the approval for a SWM site plan. If an approved SWM site plan is not completed according to §
358-23, As-built plans, completion certificate, and final inspection, within the term of validity, then Springfield Township may consider the SWM site plan disapproved and may revoke any and all permits. SWM site plans that are considered disapproved by Springfield Township shall be resubmitted in accordance with §
358-21, Resubmission of disapproved SWM site plans, of this chapter.
