A.

Scope. All uses and activities permitted as of right, special exception, or special permit in any district shall conform to the standards of performance described below and shall be so constructed, maintained, and operated so as not to be injurious or offensive to the occupants of adjacent premises by reason of the emission or creation of noise, vibration, smoke, dust or other particulate matter, toxic or noxious waste materials, odors, fire and explosive hazard or glare.

B.

Noise. Every use shall be so operated as to comply with the maximum performance standards governing noise set forth below:

1.

Objectionable noises of an intermittent nature shall be controlled so as not to become a nuisance to adjacent uses.

2.

Sound levels shall be measured with a sound level meter and associated octave band filter manufactured in compliance with standards prescribed by the American Standards Association.

3.

At no point on a property line or district boundary as indicated, shall the sound intensity level of any individual operation or plant other than the operation of motor vehicles or other transportation facilities exceed the decibel levels in either of the designated octave bands shown in the following tables:

TABLE I. ALL DISTRICTS EXCEPT INDUSTRIAL

Between 8:00 a.m. and 6:00 p.m., maximum permitted sound level (decibels)

Preferred Frequencies

TABLE II. INDUSTRIAL DISTRICTS

Between 8:00 a.m. and 6:00 p.m., maximum permitted sound level (decibels)

Preferred Frequencies

ALTERNATE TABLE III. INDUSTRIAL DISTRICT

*Apply one of these corrections only.

C.

Vibration.

1.

All districts except industrial. No use shall be operated so as to produce ground vibration noticeable without instruments at the lot line of the premises on which the use is located.

2.

Industrial districts. Any industrial operation or activity which shall cause, at any time and at any point along the nearest adjacent residential lot line, earthborn vibrations in excess of the limits set forth in Column 1 Table II is prohibited. In addition, any industrial operation or activity which shall cause, at any time and at any point along the Industrial District boundary line, earthborn vibrations in excess of the limits set forth in Column 2 is prohibited. Vibration shall be expressed as displacement in inches and shall be measured with approved equipment specified by the American Standard Association, Inc.

D.

Smoke, emissions, and other particulate matter.

1.

No use or activity shall be operated except in full compliance with the requirements, regulations, and prohibitions against air pollution as provided in the statutes and laws of the State of Florida and ordinances of Palm Beach County.

2.

In all districts every use shall be so operated as to prevent the emission of smoke from any source whatever, to a density greater than described as Number 1, on the Ringelmann Smoke Chart, provided, however, that smoke equal to, but not in excess of that shade of appearance described as Number 2 on the Ringelmann Chart may be emitted for a period or periods totaling three (3) minutes in any thirty (30) minutes. For the purpose of grading the density of smoke, the Ringelmann Chart, as published and used by the United States Bureau of Mines, and which is hereby made, by reference, a part of these regulations, shall be the standard. All measurements shall be at the point of emission.

Every use shall be so operated as to prevent the emission into the air of dust or other solid matter which may cause danger to property and health of persons or animals at or beyond the lot line of the premises on which the use is located.

E.

Odors. No use shall be operated so as to produce the emission of objectionable or offensive odors in such concentration as to be readily perceptible at any point at or beyond the lot line of the property on which the use is located. Table III, Chapter 5, "Air Pollution Abatement Manual of the Manufacturing Chemists' Association, Inc., Washington, D.C. is hereby adopted as a guide in determining the quantities of offensive odors as are the guides and standards contained in prohibitions against air pollution of the State Department of Pollution Control.

F.

Toxic or noxious matter. No use shall for any period of time, discharge across the boundaries of a lot on which it is located, toxic or noxious matter is such concentrations as to be detrimental to or endanger the public health, safety, comfort, or general welfare, or cause injury or damage to persons, property, or the use of property or land, or render unclean the water of the State to the extent of being harmful or inimical to the public health, or to animal or aquatic life, or to the use of such waters for domestic water supply industrial purposes, recreation, or other legitimate and necessary uses.

G.

Radiation. Any operation involving radiation, i.e. the use of gamma rays, x-rays, alpha and beta particles, high speed electrons, neutrons, protons and other atomic or nuclear particles, shall be permitted only in accordance with the codes, rules, and regulations of the State Board of Health and the State Department of Pollution Control.

H.

Electromagnetic radiation and interference.

1.

Radiation. No person, firm, or corporation shall operate or cause to be operated for any purpose any planned or unplanned source of electromagnetic radiation which does not comply with the current regulations of the Federal Communications Commission regarding such sources of electromagnetic radiation. Any operation in compliance with the Federal Communications Commission regulation shall be deemed unlawful if such radiation causes an abnormal degradation of performance of any electromagnetic receptor of quality and proper design. The determination of "abnormal degradation in performance" and "of quality and proper design" shall be made in accordance with good engineering principles and standards of the American Institute of Electrical Engineers, the Institute of Radio Engineers, and the Electronic Industries Association.

2.

Interference. No use, activity, or process shall be conducted which produces electromagnetic interference with normal radio or television reception in any district.

I.

Fire and explosion hazards. Each use shall be operated so as to minimize the danger from fire and explosion.

1.

All uses storing, processing or producing free or active burning material shall be located entirely within buildings or structures having exterior incombustible walls and all such buildings shall be set back at least two hundred fifty (250) feet from all lot lines.

2.

All materials or products which produce flammable or explosive vapors or gases under ordinary weather conditions shall not be permitted within one hundred (100) feet of any lot line.

3.

All buildings and structures containing explosives shall be set back from all property lines at least one hundred (100) feet.

J.

Humidity, heat, or glare.

1.

In all districts, any activity producing heat or glare shall be carried on in such a manner that such heat or glare is not perceptible at any lot line.

2.

Exposed sources of light, including bare bulbs and tubes and immediately adjacent reflecting surfaces, shall be shielded so as not to create a nuisance across lot lines. The light intensity from illumination of any kind shall not exceed fifty (50) foot lamberts at any point along the line of the lot containing the light source.
