1.
SWM site plans shall be reviewed by the Township for consistency
with the provisions of this chapter. Approval of a SWM site plan and
modification requests submitted with an application for approval of
a subdivision or land development shall be granted or denied by the
Board of Supervisors following the recommendation of the Township
Engineer. Approval of SWM site plans and waiver requests submitted
where an application for approval of a subdivision or land development
is not required shall be granted or denied by the Township's Codes
Enforcement Officer with the recommendation of the Township Engineer
where deemed necessary.
2.
Modification Requests.
A.
When reviewing a SWM site plan, whether or not the SWM site plan is included in a subdivision and/or land development plan application, the Township's Board of Supervisors may, after consulting with DEP as noted in § 23-301, Subsection 2, of this chapter with respect to any modification of the requirements in § 23-301, "General Requirements," § 23-303, "Volume Controls," or § 23-304, "Rate Controls," of this chapter, grant a modification of the requirements of one or more provisions of this chapter if the literal enforcement will enact undue hardship because of peculiar conditions pertaining to the land in question, provided that such modification will not be contrary to the public interest and that the purpose and intent of the chapter is observed.
B.
All requests for modifications from an applicant shall be in writing
and shall accompany and be a part of the application for approval
of a SWM site plan and/or a subdivision or land development plan as
applicable. The request shall state in full the grounds and facts
of unreasonableness or hardship on which the request is based, the
provision or provisions of the chapter involved and the minimum modification
necessary.
C.
The Board of Supervisors of the Township shall keep a written record
of all action on requests for modifications including any record of
consultation and/or review by DEP.
3.
SWM Site Plan Review and Approval Procedure.
A.
If a SWM site plan does not involve a subdivision and/or land development,
the review of the SWM Site, recommendations, approval, approval with
conditions or disapproval, i.e., the review and decision period, shall
occur within 45 days of submission to the Township. However, the Township,
in its sole discretion, may extend the review and decision period
another 45 days due to the nature of the application and/or site conditions.
If an extension of another 45 days is imposed or granted by the Township
beyond the first forty-five-day review and decision period designated
by this paragraph, the Township shall notify the applicant in writing
and deliver such notice to said applicant within 15 days of the decision
to extend the review and decision period by the Township.
B.
If a SWM site plan involves a subdivision and/or land development
plan, the period of time from the submission to the Township of the
subdivision and/or land development plan application which includes
SWM Plan and the approval, approval with conditions or disapproval,
i.e., review and decision period, shall be in accordance with the
procedure for approval of plats in § 508 of the Pennsylvania
Municipalities Planning Code, 53 P.S. § 10508.
C.
From the time an application for approval of a plat involving a subdivision
or land development plan, whether preliminary or final, which includes
a SWM site plan, is duly filed with the Township, no change or amendment
of this chapter or other governing ordinance or plan shall affect
the decision on such application in accordance with the provisions
of the governing ordinances or plans as they stood at the time the
application was duly filed, as specified in § 508(4)(I)
of the Pennsylvania Municipalities Planning Code, 53 P.S. § 10508(4)(I).
D.
For minor subdivisions, the Township may complete an in-house review
of the SWM site plan in lieu of a review by the Township Engineer.
For such subdivisions, the Township shall have full discretion in
determining if an in-house review is appropriate based on the scope
of the proposed improvements and the potential for impacts to the
health safety, welfare and property of the public.
E.
When a SWM site plan is required, no application for a building,
occupancy or other permit for any regulated activity shall be administratively
complete for purposes of calculating approval times until the SWM
site plan has been approved. In the case of a conditional approval,
the permits may be issued by the Township at its discretion upon acceptance
in writing by the applicant of the conditions to approval.
4.
Decision Notification Procedure. In all cases, the decision of the Township to approve or disapprove the SWM site plan shall be in writing and shall be delivered to the applicant no later than 15 business days following the decision. If the SWM site plan is disapproved, the written decision by the Township shall specify the defects in the application, describe the requirements which were not met, and shall cite the provisions of the chapter relied upon. If the SWM site plan is approved with conditions, the applicant shall accept or reject the conditions personally or in writing within five days following the receipt of the decision. Failure by an applicant to accept or reject the conditions of approval within five days shall be considered a rejection of the conditions and the approval shall be revoked. The time limit for satisfying conditions of approval shall be the time limit prescribed for conditional approval of subdivision and land development plans as stated in the Township's Subdivision and Land Development Ordinance [Chapter 22].
[Ord. 2011-8, 11/3/2011, § 404]
A revision to a previously submitted SWM site plan that involves
a change in SWM BMPs, stormwater management facilities, or changes
in analytical 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 re-submission of the revised SWM site plan in accordance
with this Part, including applicable fees. For NPDES permitted sites,
any revised SWM site plan shall also be re-submitted to the York County
Conservation District for review. In the case of a SWM site plan which
contains minor deficiencies, such as a missing label, omission of
a required note or minor construction detail, as determined by the
Township, the Township may accept a re-submission of such SWM site
plan without the requirement of a review fee, or for a lesser fee
as provided for in the Township's fee schedule.
[Ord. 2011-8, 11/3/2011, § 405]
A disapproved SWM site plan may be re-submitted, with revisions to correct all aspects of the plan that do not comply with this chapter. The applicable review fee must accompany the submission of a revised SWM site plan, unless such fee is waived by the Township. (See § 23-404).
[Ord. 2011-8, 11/3/2011, § 406]
1.
SWM Site Plans Independent of Subdivision and Land Development Plans. The Township's approval of a SWM site plan, when such plan is submitted independent of a Subdivision and/or land development 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 approved regulated activities are not completed according to § 23-407 within the term of validity, then the Township may consider the SWM site plan disapproved and may revoke any and all permits. If approved regulated activities are under construction but not completed within the term of validity, then the owner or developer shall be granted an additional 12 months beyond the original term of validity to complete the regulated activities. SWM site plans that are considered disapproved by the Township may be re-submitted in accordance with § 23-405 of this chapter.
2.
SWM Site Plans Included in a Subdivision and/or Land Development
Plan. The Township's approval of a SWM site plan, which is a part
of a Subdivision and/or Land Development Plan, authorizes that plan
and the regulated activities therein so that no subsequent change
or amendment in this chapter or other governing ordinances or plans
shall be applied to affect adversely the right of the applicant to
commence and to complete any aspect of the approved development in
accordance with the terms of such approval within five years from
such approval, as specified in § 508(4)(ii) — (vii)
of the Pennsylvania Municipalities Planning Code, 53 P.S. § 10508(4)(ii)
