A modification (revision) to a previously submitted SWM site

soil or other conditions are not as stated on the SWM site plan as
determined by Foster Township shall require a resubmission of the
modified (revised) SWM site plan in accordance with this article.
A disapproved SWM site plan may be resubmitted, with the revisions
addressing Foster Township's concerns, to Foster Township in
accordance with this article. The applicable review fee must accompany
a resubmission of a disapproved SWM site plan.
Foster Township's approval of an SWM site plan authorizes the regulated activities contained in the SWM site plan for a maximum term of validity of five years following the date of approval. Foster Township may specify a term of validity shorter than five years in the approval for any specific SWM site plan. Terms of validity shall commence on the date Foster Township signs the approval for an SWM site plan. If an approved SWM site plan is not completed according to §
192-22 within the term of validity, then Foster Township may consider the SWM site plan disapproved and may revoke any and all permits. SWM site plans that are considered disapproved by Foster Township shall be resubmitted in accordance with §
192-20 of this chapter.
