A.
SWM site plans shall be reviewed by the municipality for consistency
with the provisions of this chapter.

The municipality shall notify the applicant, in writing, within 45
days whether the SWM site plan is approved or disapproved. If the
SWM site plan involves a subdivision and land development plan, the
notification shall occur within the time period allowed by the Municipalities
Planning Code (90 days). If a longer notification period is provided
by other statute, regulation, or ordinance, the applicant will be
so notified by the municipality.
C.
For any SWM site plan that proposes to use any BMPs other than green
infrastructure and LID practices to achieve the volume and rate controls
required under this chapter, the municipality will not approve the
SWM site plan unless it determines that green infrastructure and LID
practices are not practicable.
D.
If the
municipality disapproves the SWM site plan, the municipality will
state the reasons for the disapproval in writing. The municipality
also may approve the SWM site plan with conditions and, if so, shall
provide the acceptable conditions for approval in writing.
A modification to a submitted SWM site plan that involves a
change in SWM BMPs or techniques, or that involves the relocation
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 City of Nanticoke, 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 City of Nanticoke's concerns, to the City of Nanticoke

of a disapproved SWM site plan.
The City of Nanticoke 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 City of Nanticoke 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 City of Nanticoke signs the approval for an SWM site plan. If an approved SWM site plan is not completed according to § 446-19 within the term of validity, then the City of Nanticoke may consider the SWM site plan disapproved and may revoke any and all permits. SWM site plans that are considered disapproved by the City of Nanticoke shall be resubmitted in accordance with § 446-17 of this chapter.
