   or maintain the stream stability, and preserve and protect the ecological function
   of the floodplain.

qualifying criteria set by the municipality and as follows:

1. Existing conditions, such as channel or streambank erosion and an actively enlarging or
   incising urban stream condition, shall be documented prior to restoration.
2. Projects should be located on 1^st to 3^rd order (small) streams to be effective.
3. Project should address a minimum of 100 linear feet of stream channel and both sides
   where need to do so is evident.
4. Upstream impervious area should be sufficiently treated to address peak flows that may
   exceed engineering design thresholds or compromise channel form and function.
   
5. Utilize a comprehensive approach employing a mix of techniques appropriate to the site,creating long-term stability of the streambed, streambanks and floodplain.

5. Armored length of streams (ie using riprap or gabions) may be used to maintain channel
   stability, but the same length shall not be included in the load reduction calculation.
6. Project shall maximize floodplain reconnection, with minimal channel invert elevation
   increase (ie bank height ratio = l.0 or less) to achieve the objective.
7. Project shall include a minimum 35 ft permanent riparian buffer.

   responsible parties.

      §310.                 Erosion and Sedimentation Controls.

1. No regulated development activities within Bolivar Borough shall commence until
   approval by Bolivar Borough and the WCD of an erosion and sediment control plan for
   construction activities.
2. Any earth disturbance activity of 5,000 square feet or more requires an erosion and
   sedimentation control plan under 25 Pa.Code §102.4(b). Refer to the PADEP Erosion and
   Sediment Pollution Control Manual 2012 or most recent version.
3. In addition, under Title 25 Pa.Code, Chapter 92, a DEP NPDES construction activities
   permit is required for regulated development activities.
4. Evidence of any necessary permit(s) for regulated development activities from the
   appropriate DEP regional office or Westmoreland Conservation District must be provided
   to the municipality. The issuance of an NPDES construction permit (or permit coverage
   under the Statewide General Permit (P AG-2) may satisfy the requirements under
   subsection l. upon review and approval by the municipality.
5. A copy of the erosion and sediment control plan and any permit required by DEP or the
   [Municipality] shall be available at the project site at all times.

§311.  Water Obstructions and Encroachments

1. No regulated development activities which require Chapter 105 (Water Obstructions and
   Encroachment) permit from either PA DEP or Westmoreland Conservation District shall
   commence until all permits have received P A DEP or WCD approval, and municipal
   approval.
2. Evidence of any necessary Chapter 105 permit from P A DEP / WCD shall be provided to
   the municipality.
3. Proposed development shall avoid the long and short term adverse impacts associated with
   the occupancy and modification of floodplains as designated by FEMA, to the extent
   possible wherever there is a practicable alternative in order to reduce the risk offlood loss,
   minimize the impacts of floods on human safety, health and welfare, and restore and
   preserve the natural and beneficial values served by flood plains.
4. Any proposed development found to be within the base floodplain of a waterway shall
   include the identification of impacts, an evaluation of practicable alternatives outside the
   floodplain, and when impacts cannot be avoided, the development of measures to minimize
   the impacts and restore and preserve the floodplain as appropriate. Findings shall be
   presented at a public meeting and a determination made by the Council of the Bolivar
   Borough.
   
5. Any proposed stormwater management plan should be consistent with the provisions of the PA Floodplain Management Act 166 of 1978 and applicable municipal floodplain ordinances.

ARTICLE IV   Stormwater Management Plan Requirements.

      §401.               General Requirements.

No development plan, subdivision plat or land development plan shall be
approved; no permit authorizing construction or development issued; nor any earth
disturbance activity subject to this Ordinance shall be initiated or undertaken unless and
until a stormwater management plan for such activity is reviewed and approved in accord
with the provisions of this Ordinance.

1. No regulated development activities within the municipality shall commence until
   approval by the municipality of a stormwater management plan which demonstrates
   compliance with State water quality requirements after construction is complete. Refer to
   the Regulated Development Activity Table located in Article TIl of this ordinance.
2. The stormwater management plan must be designed, implemented and maintained to meet
   State water quality requirements, and any other more stringent requirements as
   determined by the municipality.
3. To control post-construction stormwater impacts from regulated development activities,
   State water quality requirements can be met by BMPs, including site design and green
   infrastructure, which provide for replication of pre-construction stormwater infiltration
   and runoff conditions, so that post-construction storm water discharges do not degrade the
   physical, chemical or biological characteristics of the receiving waters. As described in
   the DEP Comprehensive Stormwater Management Policy (#392-0300-002, September
   28, 2002), this may be achieved by the following:

1.           Infiltration. Replication of pre-construction stormwater infiltration conditions.
2.           Treatment. Use of water quality treatment BMPs to ensure filtering out of the
   chemical and physical pollutants from the stormwater runoff.           
3.            Stream bank and Streambed Protection. Management of volume and rate of post-
   construction stormwater discharges, using detention / retention and other means, to
   prevent physical degradation of receiving waters (e.g., from scouring).

4. In the absence of an existing stormwater conveyance or easement whether natural or
   man-made for release of stormwater flow from a development site, an easement must be
   provided. Information shall be presented as to the ownership, responsible party, and
   agreement for said easement.

E. The storm water management plan must meet DEP regulations that require municipalities to ensure design, implementation and maintenance of best management practices ("BMPs") that control runoff from new development and redevelopment after regulated development activities are complete. These requirements include the need to implement post-construction stormwater facilities and BMPs with assurance oflong-term operations and maintenance of those BMPs.

6. Evidence of any necessary permit(s), such as Chapter 102 erosion and sedimentation control
   or Chapter 105 stream encroachment, for regulated development activities from WCD or the
   appropriate DEP regional office must be provided to the municipality. The issuance of an NPDES construction permit (or permit coverage under the Statewide General Permit (P AG- 2) may satisfy the requirements of paragraph (A) above, after review and approval by the municipality .

7. Appropriate sections from the municipality's Subdivision and Land Development
   Ordinance (SALDO), and other applicable local and Westmoreland County ordinances,
   shall be followed in preparing the SWM Plans. The Municipality shall not approve any
   SWM Plan that is deficient in meeting the requirements of this Ordinance. At its sole
   discretion and in accordance with this Article, when a SWM Plan is found to be deficient,
   the municipality may either disapprove the submission and require a resubmission, or in
   the case of minor deficiencies, the Municipality may accept submission of modifications.
8. Professional Certification. The stormwater management plan (including all calculations)
   must be prepared and sealed by a qualified professional with training and expertise in
   hydrology and hydraulics. Documentation of qualifications may be required by Bolivar
   Borough.
