[Ord. 763, passed 9-10-2012]
(A)
SWM plans shall be submitted to the municipality for review
by the Municipal Engineer for consistency with this chapter and the
respective Act 167 Stormwater Management Plan. Any plan found incomplete
may not be accepted for review and may be returned to the applicant.
The Municipal Engineer will review the SWM site plan for any subdivision
or land development against the municipal SALDO provisions not otherwise
superseded by this chapter.
(B)
The applicant shall respond to the Conservation District comments
on the SWM site plan prior to being considered for final approval
by the municipality.
(C)
For activities regulated by this chapter (§ 1230.105),
the Municipal Engineer will notify the applicant and the municipality
in writing, with a copy to the Building Permit Officer, within 15
calendar days, whether the SWM site plan is consistent with the stormwater
management plan.
(1)
If the Municipal Engineer determines that the SWM site plan
is consistent with the stormwater management ordinance, the Municipal
Engineer will forward a letter of consistency to the municipality,
who will then forward a copy to the applicant.
(2)
If the Municipal Engineer determines that the SWM site plan
is inconsistent or noncompliant with the stormwater management ordinance,
the Municipal Engineer will forward a letter to the municipality,
with a copy to the applicant citing the reason(s) and specific chapter
sections for the inconsistency or noncompliance. Inconsistency or
noncompliance may be due to inadequate information to make a reasonable
judgment as to compliance with the stormwater management plan. Any
SWM site plans that are inconsistent or noncompliant may be revised
by the applicant and resubmitted when consistent with this chapter.
(D)
For regulated activities under this chapter that require an
NPDES permit application, the applicant shall forward a copy of the
Municipal Engineer's letter stating that the SWM site plan is
consistent with the stormwater management ordinance to the Conservation
District. PADEP and the Conservation District may consider the Municipal
Engineer's review comments in determining whether to issue a
permit.

The municipality will not grant preliminary or final approval
to any subdivision or land development for regulated activities specified
in this chapter if the SWM site plan has been found by the Municipal
Engineer to be inconsistent with the stormwater management ordinance.
All required permits from PADEP must be obtained prior to approval
of any subdivision or land development.
(F)
No building permits for any regulated activity specified in
this chapter will be approved by the municipality if the SWM site
plan has been found to be inconsistent with the stormwater management
ordinance, as determined by the Municipal Engineer and Conservation
District, or without considering the comments of the Municipal Engineer
and Conservation District. All required permits from PADEP must be
obtained prior to issuance of a building permit.
(G)
The applicant shall be responsible for completing record drawings
of all stormwater management facilities included in the approved SWM
site plan. The record drawings and an explanation of any discrepancies
with the design plans shall be submitted to the Municipal Engineer
for final approval. In no case will the municipality approve the record
drawings until the municipality receives a copy of an approved declaration
of adequacy and/or highway occupancy permit from the PennDOT District
office, NPDES permit and any other applicable permits or approvals
from PADEP or the Conservation District. The above permits and approvals
must be based on the record drawings.
(H)
The municipality's approval of a SWM site plan shall be
valid for a period not to exceed five years commencing on the date
that the municipality signs the approved SWM site plan. If stormwater
management facilities included in the approved SWM site plan have
not been constructed, or if constructed, record drawings of these
facilities have not been approved within this five-year time period,
then the municipality may consider the SWM site plan inconsistent
or noncompliant and may revoke any and all permits. SWM site plans
that are determined to be inconsistent or noncompliant by the municipality
shall be resubmitted in accordance with § 1230.406 of this
chapter.
[Ord. 763, passed 9-10-2012]
(A)

the municipality shall be submitted to the municipality accompanied
by the applicable municipal review and inspection fee.
[Ord. 763, passed 9-10-2012]
An inconsistent or noncompliant SWM site plan may be resubmitted
with the revisions addressing the Municipal Engineer's concerns
documented in writing. It must be addressed to the municipality in
accordance with § 1230.403 of this chapter, distributed
accordingly, and be subject to review as specified in § 1230.404
