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 Board of Supervisors may, after consulting with DEP as noted in
§ 25-301.3 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

will not be contrary to the public interest and that the purpose and
intent of the Chapter is observed.
B.
All requests for a modification 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

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 shall occur within 45 days of submission
to 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
subdivisions and/or land development plan application which includes
the SWM Plan and the approval, approval with conditions, or disapproval
shall not exceed 90 days, in accordance with the procedure for approval
of plats in § 508 of the Pennsylvania Municipalities Planning
Code.
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 the 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.
4.
Decision Notification Procedure. In all cases, the decision of the

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 notification to the applicant shall state the acceptable
conditions for approval and the time limit for satisfying such conditions.
The time limit for satisfying such conditions or approval shall be
the time limit prescribed for conditional approval of subdivision
and land development plans as stated in the Township Subdivision and
Land Development Ordinance.
[Ord. 2011-09, 9/7/2011, § 404]
A revision to a previously 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 revised SWM site
plan in accordance with this Part, including applicable fees. For
NPDES permitted sites, any revised SWM site plan shall also be resubmitted
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 resubmission
of such SWM site plan without the requirement of a review fee, or
for a lesser fee as provided in the Township's fee schedule.
[Ord. 2011-09, 9/7/2011, § 405]
A disapproved SWM site plan may be resubmitted, with the revisions addressing the Township's concerns, to the Township in accordance with this Part. The applicable review fee must accompany a resubmission of a disapproved SWM site plan, unless such fee is waived by the Township (see § 25-404).
[Ord. 2011-09, 9/7/2011, § 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. The Township may specify a term of validity shorter than five years in the approval for any specific SWM site plan, particularly if the nature of the proposed SWM facilities requires more frequent maintenance and/or short-term replacement of certain components. Terms of validity shall commence on the date the Township signs the approval for a SWM site plan. If an approved SWM site plan is not completed according to § 25-407 within the term of validity, then the Township may consider the SWM site plan disapproved and may revoke any and all permits. SWM site plans that are considered disapproved by the Township may be resubmitted in accordance with § 25-405 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.
[Ord. 2011-09, 9/7/2011, § 407]

signed by a qualified person verifying that all permanent SWM BMPs
have been constructed according to the approved plans and specifications.
If any licensed qualified person contributed to the construction plans,
then a licensed qualified person must sign the completion certificate.
3.
After receipt of the completion certification by the Township, the
Township may conduct a final inspection to verify compliance with,
