A.
Smoke. The emission of gray smoke at a density greater than No. 1
on the Ringelmann Chart, published by the U.S. Bureau of Mines (Powers
Micro-Ringelmann Chart, McGraw Hill Publishing Co., 1954, may be used)
shall not be permitted except gray smoke of a shade not darker than
No. 2 may be emitted for not more than four minutes in any 30 minutes.
These provisions, applicable to gray smoke, shall also apply to visible
smoke of a different color, but with equivalent apparent opacity.
B.
Fly ash, soot and dust. The emission of particles from any flue or
smoke stack shall not exceed 0.2 grains per cubic foot of flue gas
at a stack temperature of 500° F. and 50% excess air, and shall
not cause any damage to the health of people, to animals, vegetation
or other forms of property, or cause any excessive soiling. All walks,
driveways and parking or outdoor storage areas shall be paved or dust
proofed.
C.
Noise. At no point on the boundary of a residence district, or property
line other than a residence district boundary, shall the sound pressure
level of any individual operation or plant (other than background
noises produced by sources not under the control of this chapter,
such as the operation of motor vehicles or other transportation facilities)
exceed the decibel levels in the designated octave bands shown below
for the districts indicated:

Objectionable noises due to intermittence, beat, frequency or
shrillness shall be muffled so as not to become a nuisance to adjacent
uses.
|
|
At the specified points of measurement, the sound pressure level
of noise radiated continuously from a facility shall not exceed the
values given in Table A in any octave band of frequency. The sound
pressure level shall be measured with a sound level meter and an octave
band analyzer that conform to specifications published by the American
Standards Association. (American Standard Sound Level Meters for Measurement
of Noise and Other Sound, 224.3-1944, American Standards Association,
Inc., New York, New York, and American Standard Specification for
an Octave Band Filter, Set for the Analysis of Noise and Other Sounds,
224.10-1953, American Standards Association, Inc., New York, New York,
shall be used).

D.
Odor. No emission of unpleasant gases or other odorous matter shall
be permitted in such quantities as to be offensive outside the lot
lines of the tract. Any process which may involve the creation or
emission of any odors shall be provided with a secondary safeguard
system so that control will be maintained if the primary safeguard
system should fail. There is hereby established as a guide in determining
such quantities of offensive odors, Table 3 (Odor Thresholds) in Chapter
5, Air Pollution Abatement Manual, copyright 1951 by Manufacturing
Chemists Association, Inc., Washington, D.C. Where said publication
gives a range of figures, a simple average of these shall be used.
E.
Toxic gases. The emission of gases or fumes injurious to persons
or property beyond the lot lines occupied by the use is prohibited.
(Table 1, Industrial Hygiene Standards, Maximum Allowable Concentration,
Chapter 5 of the Air Pollution Abatement Manual furnishes a list of
toxic pollutants.)
F.
Glare and heat. Glare and heat from arc welding, acetylene torch
cutting or similar processes shall be performed so as not to produce
glare which is visible, or objectionable heat, beyond the property
line of the lot on which the operation is located. Direct glare from
incandescent exposed lights shall not be visible from adjoining streets
or properties.
G.
Sewage. No discharge is permitted at any point in any private sewage
disposal system or stream or into the ground, of any materials in
such a way or such nature or temperature as could contaminate any
water supply, or otherwise cause the emission of dangerous objectionable
elements except in accordance with the standards as approved by water
pollution control boards or appropriate agencies of the Pennsylvania
Department of Environmental Protection. Furthermore, no accumulation
of solid wastes conducive to the breeding of rodents or insects shall
be permitted.
H.
Vibration. Any use creating intense earth-shaking vibration shall
be set back at least 500 feet from the lot lines on all sides, except
for lot lines along or inside the Light Industrial District where
such setback shall not be required, but in no case shall any such
vibration be perceptible along the boundary line of any zoning district
other than the Light Industrial District.
I.
Fire and safety.
(1)
All buildings containing uses involving burning materials of any
kind shall be of fireproof construction. Incombustible to moderate
burning materials permitted freely. Free or active burning to intense
burning materials must be:
(2)
This subsection shall not apply to the use of fuels if such use is
limited to storage, and movement of fuel is within appropriate containers
or pipes.
J.
Uses prohibited.
(1)
Residential subdivisions and developments and the construction of
dwellings on existing lots zoned as industrial, except for dwellings
for watchman, caretaker or farm.
(2)
Schools, hospitals, clinics or other institutions for human care,
except where incidental to a permitted principal use.
(3)
Any building for retail business or service, except where incidental
to a principal permitted use.
(4)
Junkyards.
