H.
No building permits shall be issued for any regulated activity specified in Article II of this chapter if the stormwater management plan has been found to be inconsistent with this chapter, as determined by the Municipal Engineer, or without considering the comments of the Municipal Engineer. All required permits from PA DEP must be obtained prior to issuance of a building permit.
I.
The applicant shall be responsible for completing record drawings
of all stormwater management facilities included in the approved stormwater
management plan. The record drawings and an explanation of any discrepancies

drawings until the Borough receives a copy of an approved highway
occupancy permit from the PennDOT District Office, NPDES permit, and
any other applicable permits or approvals, from PA DEP or the County
Conservation District. The above permits and approvals must be based
on the record drawings. The record drawings must include copies of
all applicable permits and approvals.
J.
The Borough's approval of a stormwater management plan shall be valid for a period not to exceed five years commencing on the date that the Borough approves the stormwater management plan. If stormwater management facilities included in the approved stormwater management plan have not been constructed, or if constructed and record drawings of these facilities have not been approved, within this time period, then the Borough may consider the stormwater management plan disapproved and may revoke any and all permits. Stormwater management plans that are considered disapproved by the Borough shall be resubmitted in accordance with § 190-25 of this chapter.
A.
A modification to a stormwater management plan under review by the Borough for a development site that involves a change in stormwater management facilities or techniques, or that involves the relocation or redesign of stormwater management facilities, or that is necessary because soil or other conditions are not as stated on the stormwater management plan as determined by the Municipal Engineer, shall require a resubmission of a modified stormwater management plan consistent with this chapter and shall be subject to review as specified in Article VI of this chapter.

costs incurred by the Borough. All fees shall be paid by the applicant
at the time of stormwater management plan submission.
B.
Any fees established pursuant to this chapter may include, but not
necessarily be limited to, any of the following:

Bonds, cash, checks or securities filed as completion guarantee shall
be returned or released upon written certification by the Borough
Engineer or a designated agent that improvements and BMPs have been
installed and completed in accordance with the standards and specifications
and that the inspection fee has been paid. Such written certification
shall be given by the Engineer within 30 days after installation and
completion of improvements and BMPs.
(3)
If improvements are not installed and completed within two years
of the date of recording for the subdivision plat or do not comply
with the standards and specifications of this chapter, the Borough
may proceed to complete the improvements and BMPs and use whatever
proceeds from bonds, cash deposits, checks or securities as are required
to meet the expense of completing such improvements.
(4)
When streets, sanitary sewers, storm drainage BMPs, waterlines or
other required improvements in the subdivision or land development
have been completed in accordance with this chapter and approved stormwater
management plan for the development site, such improvements shall
be deemed private until such time as they have been offered for dedication
to the Borough and accepted by separate ordinance or resolution, or
until they have been condemned for use as a public BMP. Prior to the
acceptance of any improvement, the Borough Engineer shall inspect
it to ensure that it is constructed in accordance with the approved
plan and is functioning properly. In the case of any stormwater control
BMP, it must be free of sediment and debris. In addition, the developer
shall submit as-built plans of all BMPs proposed for dedication.
