§ 107-23 Responsibilities for operations and maintenance of BMPs.

A. 
The BMP operations and maintenance plan for the project site shall establish responsibilities for the continuing operation and maintenance of all permanent stormwater BMPs, as follows:
(1) 
If a plan includes structures or lots which are to be separately owned and in which streets, sewers and other public improvements are to be dedicated to the municipality, stormwater BMPs may also be dedicated to and, if accepted by the Borough in its discretion, maintained by the municipality;
(2) 
If a plan includes operations and maintenance by a single ownership, or if sewers and other public improvements are to be privately owned and maintained, then the operation and maintenance of stormwater BMPs shall be the responsibility of the owner or private management entity.
B. 
The municipality shall make the final determination on the continuing operations and maintenance responsibilities. The municipality reserves the right to accept or reject the operations and maintenance responsibility for any or all of the stormwater BMPs.

§ 107-24 Municipality review of BMP operations and maintenance plan.

A. 
The municipality shall review the BMP operations and maintenance plan for consistency with the purposes and requirements of this ordinance, and any permits issued by DEP.
B. 
The municipality shall notify the applicant in writing whether the BMP operations and maintenance plan is approved.
C. 
The municipality may require an as-built survey of all stormwater BMPs, and an explanation of any discrepancies with the operations and maintenance plan.

§ 107-25 Adherence to approved BMP operations and maintenance plan.

It shall be unlawful to alter or remove any permanent stormwater BMP required by an approved BMP operations and maintenance plan, or to allow the property to remain in a condition which does not conform to an approved BMP operations and maintenance plan, unless an exception is granted in writing by the municipality.

§ 107-26 Operations and maintenance agreement for privately owned stormwater BMPs.

Other items may be included in the agreement where determined necessary to guarantee the satisfactory operation and maintenance of all permanent stormwater BMPs. The agreement shall be subject to the review and approval of the municipality.

A. 
Methods to ensure compliance with this ordinance such as stormwater management easements are required for all areas used for off-site stormwater control, unless a waiver is granted by the municipality.
B. 
Methods to ensure compliance with this ordinance such as stormwater management easements shall be provided by the property owner if necessary for 1) access for inspections and maintenance; or 2) preservation of stormwater runoff conveyance, infiltration, and detention areas and other BMPs, by persons other than the property owner. The purpose of the appropriate method shall be specified in any agreement under § 107-26.
C. 
If a conservation easement is provided, the long-term ownership, access, maintenance, and use restrictions must be identified on the recording plan.

§ 107-28 Recording of approved BMP operations and maintenance plan and related agreements.

A. 
The municipality may suspend or revoke any approvals granted for the project site upon discovery of the failure of the owner to comply with this article.
B. 
The O&M plan shall be recorded as a restrictive deed covenant that runs with the land.

§ 107-29 Municipal Stormwater BMP Operation and Maintenance Fund.

A. 
If stormwater BMPs are accepted by the municipality for dedication, the municipality may require persons installing stormwater BMPs to pay a specified amount to the Municipal Stormwater BMP Operation and Maintenance Fund, to help defray costs of operations and maintenance activities. The amount may be determined as follows:
(1) 
If the BMP is to be owned and maintained by the municipality, the amount shall cover the estimated costs for operations and maintenance for 10 years, as determined by the municipality.
(2) 
The amount shall then be converted to present worth of the annual series values.
B. 
If a BMP is proposed that also serves as a recreation facility (e.g., ball field, lake), the municipality may adjust the amount due accordingly.
C. 
The owner of the facilities to be dedicated may request the exact amount before dedication so that the owner may decide if dedication will be made.

§ 107-30 Construction criteria for stormwater control facilities.

Stormwater management facilities shall be constructed in accordance with the following minimum specifications:
A. 
All workmanship and materials shall conform to the Borough construction standards. In addition, all workmanship and materials shall conform to the latest edition of PennDOT Form 408 and be supplied by manufacturers or suppliers listed in PennDOT's Bulletin 15.
B. 
All connections to existing storm sewer pipes shall be made by construction of a suitable junction box (inlet or manhole) to provide access for clean-out. No blind connections shall be permitted.
C. 
All pipe outlets shall discharge onto a stone riprap blanket to prevent erosion of soil. Riprap shall be sized considering pipe exit velocities plus a factor of safety of 1.5.
D. 
The discharge of stormwater runoff shall be to a well-defined drainagecourse which has a defined bed and bank. If stormwater runoff cannot be discharged to a defined drainagecourse, documentation of written recorded drainage easement permission from each downstream property owner shall be provided for all properties between the source of discharge and the defined drainagecourse.

§ 107-31 Inspections of stormwater management controls during construction.

A. 
The Borough or a designated representative shall field review the construction of the temporary and permanent stormwater management facilities for the development site. The landowner shall notify the Borough 48 hours in advance of the completion of the following key development phases:
(1) 
At the completion of the preliminary site preparation, including stripping of vegetation, stockpiling of topsoil and construction of temporary stormwater management and erosion control facilities.
(2) 
At the completion of rough grading, but prior to placing topsoil, permanent drainage or other site development improvement and ground covers.
(3) 
During construction of the permanent stormwater facilities at such times as specified by the Borough.
(4) 
Completion of permanent stormwater management facilities, including established ground covers and plantings.
(5) 
Completion of any final grading, vegetative control measures or other site restoration work done in accordance with the approved plan and permit.
B. 
No work shall commence on any subsequent phase until the preceding one has been field reviewed by the Borough Engineer and approved by the Borough in writing. If there are deficiencies in any phase, the Borough shall issue a written description of the required corrections and stipulate the time by which the corrections must be made.
C. 
If during construction the contractor landowner identifies any site conditions, such as subsurface soil conditions or alterations in surface or subsurface drainage, which could affect the feasibility of the approved stormwater facilities, said person must notify the Borough within 24 hours of the discovery of such condition and request a field review by the Borough. The Borough shall determine if the condition requires a stormwater plan modification.
D. 
In cases where stormwater facilities are to be installed in areas of landslide-prone soils or where other special site conditions exist, the Borough may require special precautions, such as soil tests and core borings, full-time resident project representative services and/or similar measures. All costs of any such measures shall be borne by the permittee.

§ 107-32 Postconstruction stormwater record plan.

A. 
Prior to issuance of an occupancy permit or utilization of the proposed improvements, the applicant must provide the Borough a copy of a recorded postconstruction stormwater management plan and the proof of recording for any projects containing stormwater management facilities including storm sewers and BMPs.
B. 
The owner shall provide a digital file, on state plain coordinate system, of the location of all BMPs constructed on the property.
