A justification must be included in the SWM site plan if BMPs
other than green infrastructure methods and LID practices are proposed

A modification to a submitted SWM site plan that involves a

or redesign of SWM BMPs, or that is necessary because soil or other
conditions are not as stated on the SWM site plan, as determined by
the municipality shall require a resubmission of the modified SWM
site plan in accordance with this article.
A disapproved SWM site plan may be resubmitted, with the revisions
addressing the municipality's concerns, to the municipality in
accordance with this article. The applicable review fee must accompany
a resubmission of a disapproved SWM site plan.
The municipality'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. The municipality 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 the municipality signs the approval for an SWM site plan. If an approved SWM site plan is not completed according to §
295-24 within the term of validity, then the municipality may consider the SWM site plan disapproved and may revoke any and all permits. SWM site plans that are considered disapproved by the municipality shall be resubmitted in accordance with §
295-22 of this chapter.
