All uses and activities established after the effective date of this Zoning Code (Ordinance 74-O-128, passed October 17, 1974) shall comply with current Environmental Protection Agency standards or the following standards, whichever is greater.
(a) Noise. The sound level of any operation, other than the operation of motor vehicles or other transportation facilities, or operations involved in the construction or demolition of structures, or emergency alarm signals or time signals, or institutional or governmental or quasi-public activities, shall not exceed the decibel levels in the designated octave bands as stated below. The sound pressure level shall be measured with a sound level meter and an octave bank analyzer that conform to specifications published by the American Standards Association. Sound pressure levels shall be measured at the lot line of the property from which the emission occurs. The maximum permissible sound pressure levels for smooth and continuous noise are as follows: (All of the decibel levels stated below shall apply in each case.)
Octave Band Center Frequency (Hertz) | Maximum Permitted Sound Pressure Level (decibels re 0.0002 microbar) |
Octave Band Center Frequency (Hertz) | Maximum Permitted Sound Pressure Level (decibels re 0.0002 microbar) |
31.5 | 83 |
63 | 78 |
125 | 72 |
250 | 64 |
500 | 57 |
1,000 | 51 |
2,000 | 46 |
4,000 | 41 |
8,000 | 38 |
(b) Vibrations. No use shall cause earth vibrations or concussions detectable without the aid of instruments beyond the lot lines of the use creating the vibrations or concussions, except vibrations or concussions produced as a result of construction or demolition operations.
(c) Dust, fumes, vapors and gases.
(1) The emission of dust, dirt, fly ash, fumes, vapors or gases which can cause any damage to human health, animals, vegetation or 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 prohibited.
(2) No smoke shall be emitted from any chimney or other source which is of a visible gray opacity greater than No. 1 on the Ringelmann Smoke Chart, as published by the U.S. Bureau of Mines, except that smoke of a shade not darker than No. 2 on the Ringelmann Chart may be emitted for not more than six minutes in any 30-minute period.
(3) No emission of liquid or solid particles from any chimney or other source shall exceed 0.5 grains per cubic foot of the covering gas at any point beyond the lot line of the use creating the emission. At the source, allowable particulate matter in combustion gases shall not exceed one pound per million BTU input.
(d) Odors. No use shall emit odorous gases or other odorous matter in such quantities as to be offensive at any point on or beyond the lot lines of such use. Any process which may involve the creation or emission of any odor shall be provided with a secondary safeguard system, so that control will be maintained if the primary safeguard system fails.
(e) Heat. No use shall produce heat detectable without the aid of instruments beyond the lot lines of such use.
(f) Glare. No use shall produce a strong, dazzling light or a reflection thereof beyond the lot lines of such use.
(g) Storage and waste disposal.
(1) No highly flammable or explosive liquid, solid or gas shall be stored in bulk above ground, except in tanks or drums of fuel directly connected with energy devices or heating appliances located and operated on the same lot as the tanks or drums of fuel.
(2) All outdoor storage facilities for fuel, raw materials and products, and all fuel, raw materials and products stored outdoors, shall be enclosed by an approved safety fence.
(3) No materials or wastes shall be deposited upon a lot in such a form or manner that they may be transported off the lot by natural causes or forces, nor shall any substance which can contaminate a stream or watercourse or otherwise render such stream or watercourse undesirable as a source of water supply or recreation, or which will destroy aquatic life, be allowed to enter any stream or watercourse.
(4) All materials or wastes which might cause fumes or dust, which constitute a fire hazard or which may be edible or otherwise attractive to rodents or insects, shall be stored outdoors only if the same are enclosed in containers which are adequate to eliminate such hazards and shall be hidden from view from any street or adjacent property.
