No use shall emit odorous gases or
other odorous matter in such quantities as to be offensive at any
point on or beyond its lot lines. The guide for determining such quantities
of offensive odors shall be the 50% response level of Table 1 (Odor
Thresholds in Air) found in "Odor Threshold Determinations of 53 Odorant
Chemicals" by Gregory Leonardos, David Kendall and Nancy Barnard published
in the Journal of the Air Pollution Control Association, Volume 19,
Number 2, February 1969.
A.
No highly flammable or explosive liquids, solid or gases shall
be stored in bulk above the ground, except the following:
(1)
Tanks or drums of fuel, regardless of size, connected directly
with energy devices or heating appliances located and operated on
the same lot as the tanks or drums of fuel, specifically designed
to handle the material.
(2)
Tanks or drums for storage of less than 300 gallons of fuel
oil or gasoline, provided that such tanks are located no closer than
25 feet to any building or lot line or 50 feet from any street line.
(3)
In addition to Borough standards, any individual storing flammable
or explosive liquid must abide by PADEP and Allegheny County requirements.
B.
No materials or wastes shall be deposited upon a lot in such
form or manner that they shall be transported off the lot by natural
causes or forces; nor shall any substance which can contaminate wells,
watercourses or potable water supplies or otherwise render such wells,
watercourses or potable water supplies undesirable as sources of water
supply or recreation; nor shall any substance which will destroy aquatic
life be allowed to enter any wells, watercourses or potable water
supplies.
C.
Any materials or wastes which might cause fumes or dust or which
constitute a fire hazard or which shall be edible or otherwise attractive
to rodents or insects shall be stored outdoors only if enclosed in
containers adequate to eliminate such hazards.
D.
All existing storage and water disposal facilities that do not
conform to this section are hereby declared a public nuisance and
shall be brought into conformity with this section within three years
of adoption of this chapter.
E.
Any activity involving the use or storage of flammable material
shall be controlled by the requirements contained in the applicable
National Fire Protection Association Code standards.
No emission at any point from any chimney or otherwise of visible
smoke from commercial and industrial uses in excess of that permitted
by the Department of Environmental Protection (DEP) shall be permitted.
A.
The emission of dust, dirt, fly ash, fumes, vapors or gases
which can cause any damage to human health, to animals, to vegetation
or to property ,or which can cause any soiling or staining of persons
or property at any point beyond the lot line of the use creating the
emission, is herewith prohibited.
B.
No emission of liquid or solid particles from any chimney or
other source shall exceed 0.3 grain per cubic foot of the carrying
gas at any point beyond the lot line of the use creating the emission.
For measurement of the amount of particles in gases resulting from
combustion, standard correction shall be applied to a stack temperature
of 500° F. and 50% excess air in the stack at full load.
C.
Air pollution requirements shall meet Allegheny County Health
Department rules and regulations.
No use shall produce a strong light or a reflection of a strong
light greater than 0.1 footcandle beyond its lot lines or onto any
public street. Street lighting beyond 0.1 footcandle is permitted
if approved by Borough Council.
The ambient sound level of any operation (other than the operation
of motor vehicles or other transportation facilities, operations involved
in the construction or demolition of structures, emergency alarm signals
or time signals) shall not exceed the decibel levels listed in Table
21-1.
A.
The sound pressure level or ambient level is the all-encompassing
noise associated with a given environment, being a composite of sounds
from any source, near and far. For the purpose of this chapter, "ambient
noise level" is the average over 15 minutes of the alleged offensive
noise, excluding random or intermittent noises. A reading to determine
the average ambient noise level shall be conducted a minimum of three
times during any fifteen-minute period.
B.
It shall be unlawful for any person to operate any fixed machinery
or equipment or similar mechanical device in any manner so as to create
any noise which would cause the noise level measured at the property
line of the property affected by the noise emission to be beyond permitted
levels.
(1)

Editor's Note: Former Subsection B(2), concerning measurement
locations on a boundary between two zoning districts, which immediately
followed this table, was repealed 11-20-2013 by Ord. No. 606-2013.
No discharge at any point into any private sewage disposal system
or stream or into the ground of any materials in such a way or in
such nature or temperature as can contaminate any water supply or
otherwise cause the emission of dangerous or objectionable elements
or the accumulation of solid wastes conducive to the breeding of rodents
or insects is permitted.
A.
Fences, walls and electric fences. No walls, fences, signs or
other structures shall be erected or altered, and no hedge, tree,
shrub or other growth shall be maintained or permitted that shall
cause damage to traffic on a public street by obscuring the view.
The maximum permitted height of a fence in the rear and side yard
shall be six feet. Fences in the front yard shall be no higher than
four feet and at least fifty-percent open and not of the chain-link
or wire type generally used for enclosure or containment. On a corner
lot, the side yard abutting the right-of-way shall be considered a
front yard for fencing purposes. Along arterial roads, fences may
be six feet in height and may be open (anything less than one-hundred-percent
screening) or solid.
B.
Higher fences between properties in different zoning districts
shall be authorized or required at the time of site plan approval.
Higher fences along lot lines adjacent to swimming pools or commercial
properties shall be authorized by the Borough Council when necessary
for effective buffering. Higher fences around recreational facilities
or recreation areas may be required by Council. Electrified fences,
fences with barbed wire or razor wire, or barbed- or razor-wire electrified
fences are not permitted in any residential district except as shall
be authorized by Borough Council. Aboveground electrical fences as
authorized by Borough Council are subject to the following conditions:
(1)
Electric fences are permitted on farms only, except as shall
be authorized in other areas by Borough Council.
(2)
Warning signs at least three inches by 12 inches shall be placed
on the fence every 25 feet and at least three feet from ground level.
(3)
The wire carrying the current shall be placed on the inside
fence perimeter.
(4)
Maximum voltage shall not exceed 12 volts.
(5)
Electric fences shall be properly installed with an approved
charger.
(6)
The placement of the electrified fence should be carefully considered
so that it is further away from bus stops, playgrounds, school yards
or any type of pedestrian path or facility subject to heavy pedestrian
traffic.
C.
Activity affecting atmosphere at lot lines. No activities producing
heat, cold, dampness or significant movement of air are permitted
which shall produce any material effect on the temperature, motion
or humidity of the atmosphere at the lot line or beyond.
No use shall cause earth vibrations or concussions in excess
of the standards outlined below in Table 21-2, with the exception
of that vibration produced as a result of construction activity. Vibration
shall be expressed as displacement in inches and shall be measured
with a standard three-component measuring system, which is a device
for recording the intensity of any vibration in three mutually perpendicular
directions.

the standards established by the United States Nuclear Regulatory
Regulations, Title 10, Code of Federal Regulations, Part 20, Standards
for Protection Against Radiation, as may be amended from time to time.
