§ 105-79 Performance standards.
A building permit or certificate of occupancy shall be issued only when the intended use will not exceed the following limitations or violate the following requirements. All standards, including but not limited to radiation, smoke emission, solid particle emission or stream or noxious gas emission, shall be in accordance with regulations by the Air Pollution Code of New Jersey, Department of Environmental Protection, and shall meet the maximum standards as set forth therein.
A.
Fire and explosion hazards. All activities shall be carried on only in fireproof structures which conform to the standards of the National Board of Fire Underwriters or the Township Building Code[1] or Fire Prevention Code, whichever is the more restrictive.

B.
Radioactivity. Any industry which emits radioactivity is prohibited.
C.
Odors. There shall be emission of odorous gases or other odorous matter in such quantity as to be readily detectable without instruments. Table III, Odor Thresholds, in Chapter 5 of the Air Pollution Abatement Manual, copyright 1951, by the Manufacturing Chemists Association, Inc., Washington, D.C., or the latest approved revision thereof, shall be utilized as a guide in determining such quantities of offensive odors.
D.
Smoke. There shall be no emission of visible gray smoke of a shade darker than No. 1 on the Ringelmann Smoke Chart, as published by the United States Bureau of Mines (Power's Micro-Ringelmann Chart, McGraw Hill Publishing Company, copyright 1954, may be used), except that visible gray smoke of a shade not darker than No. 2 on said chart shall be emitted for not more than five minutes in any one-hour period. These provisions, applicable to visible gray smoke, shall also apply to visible smoke of a different color but with an equivalent apparent opacity.
E.
Dust. Solid or liquid particles shall not be emitted in concentrations exceeding 0.2 grain per cubic foot of the conveying gas or air. For measurement of the amount of particles in gases resulting from combustion, standard corrections shall be applied to a stack temperature of 500° F.) and fifty-percent excess air.
F.
Gases and other forms of air pollution. No emission of fly ash, dust, fumes, vapors, gases or other forms of air pollution shall be permitted which can cause any damage to the health of persons, animals or vegetation or other forms of property or which can cause any excessive soiling.

(1)
At no point on the boundary of the property on which a use is conducted shall the sound pressure level of any individual operation or plant, other than background noises produced by sources not under 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:
Octave Band (cycles per second) | Sound Pressure Level (decibels) | |
|---|---|---|
0 to 75 | 72 | |
75 to 150 | 67 | |
150 to 300 | 59 | |
300 to 600 | 52 | |

Measurements shall be made using the flat network of the sound level meter. Impulsive-type noises shall be subject to the performance standards hereinbefore prescribed, provided that such noises shall be capable of being accurately measured with such equipment. Noise capable of being so measured, for the purpose of this chapter, shall be those noises which cause rapid fluctuation of the needle of the sound level meter with a variation of no more than plus or minus two decibels.
(3)
Noises incapable of being measured as indicated above, such as those of an irregular and intermittent nature, shall be controlled so as not to become a nuisance.
I.
Liquid or solid wastes.
(1)
No industrial operation shall discharge industrial wastes of any kind into any reservoir, pond or lake or into the ground. The discharge of untreated industrial wastes into a stream is prohibited.

In addition, no industrial use shall discharge into any public sanitary sewer system quantities of water beyond the capacity of said sewer system. The amount of effluent permitted shall be determined by the Township Engineer.
J.
