The following provisions, standards, and specifications shall apply to all districts:
(A) Fire and explosion hazards. All activities involving, and all storage of, inflammable and explosive materials shall be provided at any point with adequate safety devices against the hazard of fire and explosion and adequate firefighting and fire suppression equipment and devices standard in the industry. Burning of waste materials in open fires shall be prohibited at any point. Fire and explosion hazards shall be further subject to applicable federal, state, and local laws and regulations.
(B) Radioactivity or electric disturbances. No activities shall be permitted which emit dangerous radiation. Radioactive emissions shall be further subject to applicable federal, state, and local law and regulations.
(1) In nonindustrial districts, no vibration shall be permitted which is discernible without instruments beyond the property line of the source.
(2) In industrial districts, there shall be no operation or activity which would cause ground transmitted vibrations in excess of the limits set forth below at the boundary of this district under any conditions, nor beyond the property line if it would adversely affect any other use within the district.
Maximum Vibration Levels
Frequency (Cycles per second)
Maximum Permitted Displacement at Industrial District Boundaries (in inches)
0 to 10
10 to 20
20 to 30
30 to 40
40 and over
(3) Vibrations shall be further subject to applicable federal, state, and local law and regulations.
(1) No emission of odorous gases or other odorous matter in such quantities as to be readily detectable shall be permitted beyond the property lot lines of the source. 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.
(2) Odors shall be further subject to applicable federal, state, and local law and regulations.
(E) Smoke. No emission shall be permitted of visible grey smoke of a shade equal to or darker than No. 2 on the Ringlemann chart, except that visible grey smoke of a shade to No. 3 of that chart may be emitted 4 minutes in any 30 minutes. These provisions applicable to visible grey smoke may be waived for periods of no more than 1 year.
(F) Fly ash, dust, fumes, vapors, gases, and other forms of air pollution.
(1) No emission shall be permitted which can cause any damage to health, to animals, vegetation or other forms of property, or which can cause any excessive soiling, at any point. No sulfur compound shall be emitted which would result in a ground level concentration of sulfur dioxide at the property line or beyond in excess of 1.0 part per million in a 20-minute period of any hour, or average exposure in excess of 0.1 part per million in any hour period, nor shall any gas be emitted which contains sulfur dioxide in excess of 2,000 parts per million.
(2) Fly ash, dust, fumes, vapors, gases, and other forms of air pollution shall be further subject to applicable federal, state, and local laws and regulations.
(G) Glare or heat.
(1) All lighting shall be arranged so as to deflect light away from any adjoining residences. No direct or sky-reflected glare, whether from floodlights or from high temperature processes such as combustion, welding or otherwise, so as to be visible at the property lot line of the source, shall be permitted.
(2) Glare and heat shall be further subject to applicable federal, state, and local laws and regulations.
(H) Liquid and solid waste.
(1) No wastes shall be discharged in the public sewer system which are dangerous to the public health and safety. No waste shall be discharged into a storm sewer or roadside ditch or drainage area except clear and unpolluted water.
(2) Liquid and solid waste shall be further subject to applicable federal, state, and local laws and regulations
(1) The maximum permissible sound pressure levels at specified points of measurement for noise radiated continuously from a facility is shown below.

Decibels: 0.002 dyne/cm2
7:00 a.m. to 10:00 p.m.
10:00 p.m. to 7:00 a.m.
(2) Frequencies and sound levels shall be measured with an Octave Band Analyzer and Sound Level Meter which comply with the USA Standards prescribed by the United States of America Standards Institute. All noise shall be muffled or otherwise controlled as not to become objectionable due to intermittence, duration, beat frequency, impulse character, periodic character, or shrillness.
(3) Noise shall be further subject to applicable federal, state, and local laws and regulations.
