A. Noise: Sound levels shall be measured with a sound level meter and associated octave band filter manufactured according to standards prescribed by the American Standards Association. Measurements shall be made using the flat network of sound level meter and shall include continuous noise and those noises which cause rapid fluctuations of the needle of the sound level meter with a variation of not more than plus or minus two (±2) decibels. Noise incapable of being so measured shall be measured with the impact noise meter manufactured by the general radio company, or its equivalent, and shall comply with the applicable performance standards for noise.
At no point on the boundary of a residence or business district shall the sound pressure level of any individual operation or plant (other than background noises produced by sources not under control of this ordinance, such as operation of motor vehicles or other transportation facilities) exceed the decibel levels in the designated octave bands shown in the following table:
MAXIMUM PERMITTED SOUND LEVEL
(Decibels)
B. Vibration: No industrial operation or activity (except those not under the direct control of the manufacturer) shall cause at any time ground transmitted vibrations in excess of the limits set forth below. Vibration shall be measured at any point along a residential district boundary with a three (3) component measuring instrument approved by the county zoning enforcing officer and shall be expressed as displacement in inches.

0 to 10 | .0006 |
10 to 20 | .0004 |
20 and over | .0001 |
C. Smoke And Particulate Matter: The emission of smoke or particulate matter in such manner or quantity as to endanger or to be detrimental to the public health, safety, comfort or welfare shall henceforth be unlawful.
For the purpose of grading the density of smoke, the Ringelmann chart published by the U.S. bureau of mines shall be employed. The emission of smoke or particulate matter of density greater than no. 2 on the Ringelmann chart, or in quantity of more than eight (8) smoke units per hour per stack, is prohibited at all times except as otherwise provided hereinafter.
During one 1-hour period in each twenty four (24) hour day, and only during that length of time, each stack may exceed these limits when blowing soot or cleaning fires. Smoke of Ringelmann no. 3 density or greater shall then be permitted for not more than three (3) minutes per period.
Dust and other types of air pollution, borne by wind from such various sources as storage areas, yards, roads, and the like within lot boundaries, shall be kept to a minimum by appropriate landscaping, paving, oiling, fencing, or other acceptable means.
The rate of emission of particulate matter from all sources within the boundaries of any lot shall not exceed a net figure of one pound per acre of lot area during any one hour.
D. Toxic Or Noxious Matter: No use for any period of time shall discharge across the boundaries of the lot wherein it is located, toxic or noxious matter in such concentration as to be a nuisance or detrimental to or endanger the public health, safety, comfort, or welfare, or cause injury or damage to property or business.
E. Odors: The emission of odorous matter in such concentrations as to be readily detectable at any point along the boundaries of the property or in such concentrations as to create a nuisance or hazard beyond such boundaries is prohibited.
1. The storage, utilization or manufacture of solid materials or products ranging from incombustible to moderate burning is permitted.
2. The storage, utilization or manufacture of solid materials or products ranging from free to active burning to intense burning is permitted provided the following conditions are met:
a. Said materials or products shall be stored, utilized or manufactured within completely enclosed buildings or structures having incombustible exterior walls and handled in accordance with the standards and regulations of the county of Kane and the National Fire Protection Association.
b. All such buildings shall be set back at least forty feet (40') from all lot lines, or in lieu thereof shall be protected throughout by an automatic fire extinguishing system installed in accordance with the standards and regulations of the county of Kane and the National Fire Protection Association.
3. The storage, utilization or manufacture of flammable liquids or materials which produce flammable or explosive vapors under ordinary weather temperatures, shall be permitted in accordance with the following limitations, exclusive of storage in underground tanks and exclusive of storage of finished products in original sealed containers:
a. Said materials or products shall be stored, utilized or manufactured within completely enclosed buildings or structures having incombustible exterior walls and handled in accordance with the standards and regulations of the county of Kane and the National Fire Protection Association.
b. All such buildings shall be set back at least forty feet (40') from all lot lines or in lieu thereof shall be protected throughout by an automatic fire extinguishing system installed in accordance with the standards and regulations of the county of Kane and the National Fire Protection Association.
c. The storage of flammable liquids in excess of the following quantities shall not be permitted:
| |
Less than 24°F | 1,000 |
24°F to less than 105°F | 10,000 |
105°F to less than 187°F | 50,000 |
Total of all flammable liquids permitted | 50,000 |
4. Activities involving the storage or manufacture of materials or products which decompose by detonation are not permitted in an LI district.
G. Glare-Heat-Flash: Any operation producing intense glare, heat or flash shall be performed within a completely enclosed building in such manner as not to create a nuisance or hazard along lot lines.
1. Airborne radioactive materials shall not exceed at any point on or beyond the lot line the lowest concentration permitted for the general population by applicable federal and state laws and regulations in effect.
2. No activity involving radiation hazards shall be permitted which cause to any individual who may be continuously at any point on or beyond the lot line, radiation in excess of the smallest amount permitted in the applicable federal and state laws and regulations.
