view of vision for vehicular traffic.
(2) Fences, walls or screens shall not contain barbs or similar types
of injurious hazards, unless specifically approved by the Planning
Commission for security reasons.
(3) All planted screens required by the chapter shall be of sufficient
density and type of planting material to provide a year-round visual
barrier within two growing seasons of planting. The minimum height
shall be six feet, but the Planning Commission may require greater

15 days of receipt of the notice. In the event the owner fails to
comply with the order, the owner shall be considered in violation
of this chapter and subject to the penalties contained herein.
(3) If a fence, wall or screen is destroyed or deteriorates beyond 50%
of its total linear displacement, then it must be removed within 15
days of receipt of written notice from the Zoning Officer.
All uses hereafter established in any zoning district shall
comply with the performance standards contained in this section. The
performance standards shall apply to an existing use or structure,
or portion thereof, when it is extended, enlarged, moved, structurally
altered, or reconstructed.
A. Fire and explosive hazards. All activities and all storage of flammable
and explosive material at any point shall be provided with adequate
safety devices against the hazards of fire and explosion, and adequate
firefighting equipment as specified by the Department of Labor and
Industry and the laws of the Commonwealth of Pennsylvania. All buildings
and structures and activities within such buildings and structures
shall conform to the Borough's Building Code (Ord. No. 1159,
as amended,) and all other applicable Borough ordinances.
B. Radioactivity or electrical disturbances. There shall be no activities
which emit radioactivity at any point above the most recent background
limits set by state and/or federal regulations. There shall be no
radio or electrical disturbance in excess of that permitted by federal
law or regulation.
C. Smoke, ash, dust, fumes, vapors and gases. There shall be no emission
of smoke, ash, dust, fumes, vapors or gases which violates applicable
federal, state or Allegheny County laws and regulations.
D. Liquid and solid wastes. There shall be no discharge at any point
into any public or private sewerage system, or watercourse or into
the ground, of any materials in such a way or of such a nature as
will contaminate or otherwise cause the emission of hazardous materials
in violation of the laws and regulations of the Commonwealth of Pennsylvania
and Allegheny County. All required discharge and disposal permits
shall be obtained.
E. Glare. No direct reflected glare, whether from any lighting source
or production operation, shall be visible from adjoining public streets
or adjacent lots when viewed by a person standing on ground level.
"Glare" shall be defined as direct or indirect light from such activities
of greater than 0.5 footcandle at habitable levels.
F. Odor. There shall be no emission of odorous gases or other matter
in such quantities as to be offensive on adjoining streets or adjacent
lots. Odor thresholds shall be measured in accordance with ASTM D-1391-57
"Standard Method for Measurement of Odor in Atmospheres (Dilution
Method)."
G. Noise.
(1) No operation or activity shall cause or create noise in excess of
the sound levels prescribed below. For the purposes of this chapter,
the noise level will be measured in decibels (dBA) which indicate
the sound pressure level obtained from a frequency weighting network
corresponding to the A-scale on a standard sound level meter.
(a)
"R-1", "R-2" and "C" Districts. At no point on or beyond the
boundary of any lot within these districts shall the exterior noise
level resulting from any use or activity located on such lot exceed
a maximum of 85 dBA for more than three hours per 24 hours.
(b)
"B-1" and "B-2" Districts. At no point on or beyond the boundary
of any lot within these districts shall the exterior noise level resulting
from any use or activity located on such lot exceed a maximum of 95
dBA for more than eight hours per 24 hours.
(c)
"I" District (including "S-1"). At no point on or beyond the
boundary of any lot within these districts shall the exterior noise
level resulting from any use or activity located on such a lot exceed
a maximum of 115 dBA.
(d)
Where two zoning districts in which different noise levels are
prescribed share a common boundary, the most restrictive of the noise
level standards shall govern.
(2) The following uses or activities shall be exempted from the noise
regulations:
(a)
Noises emanating from construction and/or maintenance activities
between 7:00 a.m. and 7:00 p.m.; and
(b)
Noises caused by safety signals, warning devices and other emergency-related
activities or uses.
(3) In addition to these regulations, all uses or activities within the
Borough shall conform to any applicable county, state, or federal
noise regulations.
H. Storage. All garbage, trash and rubbish shall be stored in covered,
vermin-proof containers, and also shall be screened from public view.
I. Determination of compliance.
(1) If, during the review of a zoning application, it appears that the
proposed use or development may violate the performance standards
contained in this section, the Borough may initiate an investigation
and may require the applicant to submit such data and evidence as
is needed to make an objective determination. The evidence may include
such items as:
(a)
Plans of the existing or proposed construction and development.
(b)
A description of the existing or proposed machinery, processes
and products.
(c)
Specifications for the mechanisms and techniques used or proposed
to be used or proposed to be used in restricting the possible emission
of any of the dangerous and objectionable elements, as set forth in
this article.
(d)
Measurements of the amount of rate of emissions of said dangerous
and objectionable elements.
(2) In order to determine compliance, the Borough may seek assistance
from any county, state or federal agency having interest in or jurisdiction
for the particular environmental issue. The Borough may also require
the applicant to submit a report from a qualified technical expert
certifying that the proposed use does comply with the performance
standard(s). The technical expert shall be persons or firms mutually
acceptable to the Borough and applicant; in the event agreement cannot
be reached on the technical expert, the Borough shall make the selection.
The cost of the expert's study and report shall be borne by the
applicant. A negative report by the technical expert, as to the proposed
use's compliance with the performance standard(s), and the applicant's
refusal or inability to make alterations to ensure compliance, shall
be a basis for denying approval of the zoning application.
J. Continuing enforcement.
(1) The Zoning Officer shall investigate any purported violation of the
performance standards and, if necessary, request that the Borough
employ qualified experts to assist in the determination of a violation.
The costs for the services of such experts shall be paid by the owner
or operator of the facility accused of the violation.
(2) If the facility is found to be in violation, the owner or operator
shall be given a reasonable length of time to correct the violation.
If, at the conclusion of this time period, the violation still exists,
and the Borough has agreed to no time extension, the owner or operator
shall be in violation of this chapter and subject to the legal penalties
and remedies contained herein.
