Editor's Note: See 53 P.S. § 10101 et seq.
B.
For SWM site plans that do not require subdivision and land development
approval, the Township shall notify the applicant in writing within
45 calendar days whether the SWM site plan is approved or disapproved.
If the SWM plan involves a subdivision and land development plan,
the notification period is 90 days. If a longer notification period
is provided by other statute, regulation, or ordinance, the applicant
will be so notified by the Township. If the Township disapproves the
SWM plan, the Township shall cite the reasons for disapproval 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 Township, 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 Township's concerns, in accordance with this article.
The applicable review fee must accompany a resubmission of a disapproved
SWM site plan.
The 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. Terms of validity shall commence on the date the Township signs the approval for an SWM site plan. If an approved SWM site plan is not completed according to § 249-21 within the term of validity, then the Township may consider the SWM site plan disapproved and may revoke any and all permits issued by the Township. SWM site plans that are considered disapproved by the Township shall be resubmitted in accordance with § 249-19 of this chapter.
The applicant may be required to provide as-built plans of all
SWM BMPs included in the approved SWM site plan. The as-built plans
and an explanation of any discrepancies with the construction plans
shall be submitted to the Township. The landowner must notify the
Township seven days prior to starting construction on improvements
proposed by an approved SWM site plan.
