resources during development and redevelopment and should be consulted. Refer to
www.paiwrp.com for the decision-making tool and www.westmorelandstormwater.org.
- Applicants should refer to the Westmoreland County Integrated Water Resources Plan
(JWRP) located at www.westmorelandstormwater.org, for mapping of impaired streams,
riparian buffers and pollutant loading to determine appropriate BMPs to address sources
- Before submitting the storm water management plan, and any other plan required by a
reviewing agency, applicants are urged to consult with the municipality, Westmoreland
County Department of Planning and Development and Westmoreland Conservation
District, and PennDOT where applicable, on the requirements for safely managing the

§502. Stormwater Management Plan Submission and Review.
- Submission of Plans. Stormwater management plan application shall be submitted with
the preliminary and final subdivision/land development applications or if no subdivision
or land development is involved, then with the application for development.
Copies of the SWM Site Plan shall be submitted to the following agencies as
determined by Bolivar Borough:

available to the affected municipalities upon request. Comments received from any
affected municipalities will be considered by the Bolivar Borough engineer and County
agencies in their reviews.
- Review by Bolivar Borough Engineer and Westmoreland Conservation District (WCD).
Stormwater management plans shall be reviewed by the municipality engineer and
WCD. HMPs shall be shown on all stormwater management plans and erosion and
sedimentation control plans, as applicable. At its discretion, the municipality and/or
WCD may also engage other specialists in hydrology or hydraulics to assist with the
stormwater management plan review. The WCD will review the plan for general
compliance with the watershed plan standards and criteria and watershed-wide impacts
and, where appropriate, may consult with adjacent municipalities and counties for their
comments. If the WCD review identifies the improper application of the watershed
standards and criteria or the possibility of harmful impacts downstream from the
development site's proposed stormwater management system, the applicant and
municipality engineer will be notified so that the necessary modifications can be made
to promote safe stormwater management.
The municipality and the WCD shall notify the applicant in writing within 45 days
whether the SWM site plan is approved or disapproved. If the SWM site plan involves
a subdivision and land development plan, the notification shall occur within 90 days,

- Permits Required From Other Governmental Agencies. Where the proposed
development requires a permit from the Pennsylvania DEP, PennDOT, or an
erosion/sedimentation permit or Chapter 105 permit from the Westmoreland
Conservation District, then final stormwater management plan approval shall be
conditional upon receipt of such permits. However, no building permit shall be issued,
nor construction or development started, until the permits are received and copies filed
with the municipality.
- Reviews by the Municipality and WCD may be subject to fees as outlined in Article vn
section 706 of this Ordinance.
§503. Status of Stormwater Management Plan after Approval.

offinal approval of the stormwatermanagement plan, then before doing so, the applicant
shall re-submit the stormwater management plan, BMPs plan or erosion or
sedimentation plan to verify that no condition has changed on the property, adjacent to
the site or within the watershed that would affect the feasibility or effectiveness of the
previously approved stormwater management controls. Further, if for any reason
development activities are suspended for  years or more, then the same requirement
for re-submission of the stormwater management plan shall apply.
§504. Modification of Stormwater Management Plan.
If the request for a plan modification is initiated before construction begins, the stormwater
management plan must be resubmitted and reviewed according to the procedures, contained in
A. If the request for a plan modification is initiated after construction is underway, the Bolivar
Borough Engineer and / or the WCD shall have the authority to approve or disapprove the
modification based on field conditions; provided:
- The requested changes in stormwater controls do not result in any modifications to
other approved municipality land use/development requirements (e.g., building
setbacks, yards, etc.).
- The performance standards in this Ordinance are met. Notification of the
Engineer's and / or weD's action shall be sent to the Bolivar Borough Council
which may issue a stay of the plan modification within 5 days and require the
permittee to re-submit the plan modification for full stormwater management plan
review in accordance with this ordinance.
