Any use established in manufacturing districts which involves the manufacturing, fabricating, assembly, disassembly, repairing, storing, cleaning, servicing, or testing of materials, goods, or products shall be operated in such a manner as to comply with applicable performance standards as hereinafter set forth governing noise, smoke, particulate matter, toxic or noxious matter, odors, fire and explosive hazards, or vibration, glare, or heat, and no use already established on the effective date hereof shall be so altered or modified as to conflict with, or further conflict with, such applicable performance standards. The application for a building permit shall be accompanied by a certification from a recognized testing laboratory selected from a panel approved by the village board.
1. 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 the sound level meter. Impulsive type noises shall be subject to the performance standards hereinafter prescribed; provided, that such noises shall be capable of being accurately measured with such equipment. Noises capable of being so measured, for the purpose of this title, shall be those noises which cause rapid fluctuations of the needle of the sound level meter with a variation of no more than plus or minus two (±2) decibels. Noises incapable of being so measured, such as those of an irregular and intermittent nature, shall be controlled so as not to become a nuisance to adjacent uses.
2. At no point on the boundary of a residence or business district 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 the designated octave bands shown in the following table: (Ord. 69-12, 4-23-1969)
(Ord. 69-12, 4-23-1969; amd. 2012 Code)
B. Smoke And Particulate Matter:
1. 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 is hereby declared to be a public nuisance and shall henceforth be unlawful.
2. For the purpose of grading the density of smoke, the Ringelmann chart, published and used by the United States bureau of mines, shall be employed. The emission of smoke or particulate matter of a density greater than no. 2 on the Ringelmann chart is prohibited at all times, except as otherwise provided hereinafter.
3. The emission, from all sources within any lot area, of particulate matter containing more than ten percent (10%) by weight of particles having a particle diameter larger than forty four (44) microns is prohibited.
4. Dust and other types of air pollution, borne by the wind from such 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 acceptable means. Emission of particulate matter from such sources in excess of the weight limitation hereinafter specified is prohibited.
5. The emission of more than eight (8) smoke units per hour per stack is prohibited, including smoke of a density in excess of Ringelmann no. 2. However, during one 1-hour period in each twenty four (24) hour day, each stack may emit up to sixteen (16) smoke units when blowing soot or cleaning fires. Only during fire cleaning periods, however, shall smoke of Ringelmann no. 3 be permitted, and then for not more than three (3) minutes.
C. Toxic Or Noxious Matter: No use shall, for any period of time, discharge across the boundaries of the lot wherein it is located, toxic or noxious matter in such concentrations as to be detrimental to or endanger the public health, safety, comfort, or welfare, or cause injury or damage to property or business.
D. Odors: The emission of odorous matter in such a quantity as to be readily detectable at any point along lot lines, or as to produce a public nuisance or hazard beyond lot lines, is prohibited.
E. Fire And Explosion Hazard:
1. The storage, utilization, or manufacture of materials or products ranging from incombustible to moderate burning, as determined for liquids by a closed cup flashpoint of not less than one hundred eighty seven degrees Fahrenheit (187°F), is permitted subject to compliance with all other performance standards for this district.
2. The storage, utilization, or manufacture of materials or products ranging from free or active burning to intense burning, as determined for liquids by a closed cup flashpoint of less than one hundred eighty seven degrees Fahrenheit (187°F) but not less than one hundred five degrees Fahrenheit (105°F), is permitted subject to compliance with all other performance standards for this district, and provided the following conditions are met:
a. Said materials or products shall be stored, utilized, or produced within completely enclosed buildings or structures having exterior walls of fire resistive construction in accordance with other provisions of this code.
b. Unless otherwise provided in this title, all such buildings or structures shall be set back at least forty feet (40') from lot lines, or in lieu thereof, all such buildings or structures shall be protected throughout by an automatic sprinkler system complying with installation standards prescribed by the National Fire Protection Association, or if the materials, goods, or products are liquids, the protection thereof shall be in conformity with standards prescribed by the National Fire Protection Association.
3. The utilization in manufacturing processes of materials which produce flammable or explosive vapors or gases, as determined for liquids by a closed cup flashpoint of less than one hundred five degrees Fahrenheit (105°F), shall be permitted in this district; provided:
a. That the final manufactured product does not itself have a closed cup flashpoint of less than one hundred eighty seven degrees Fahrenheit (187°F);
b. That the use and storage of such materials shall be in conformity with standards prescribed by the National Fire Protection Association and with the requirements of other provisions of this code; and
c. That the storage of said materials shall be prohibited aboveground.
F. Glare Or Heat: Any operation producing intense glare or heat shall be performed within a completely enclosed building in such a manner as not to create a public nuisance or hazard along lot lines.
G. 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 (the periodic displacement, measured in inches, of earth) shall be measured at any point along a residence district boundary line with a three (3) component measuring instrument approved by the village board, and shall be expressed as displacement in inches as follows:
