Where:
D = The maximum allowable displacement in inches
f = The vibration frequency in cycles per second
3. Smoke And Particulate Matter:
a. General Limitations: In addition to the performance standards specified hereinafter, the emission of smoke or particulate matter in such manner or quantity as to be detrimental to or endanger the public health, safety, comfort, or welfare is hereby declared to be a public nuisance and shall henceforth be unlawful.
Particulate matter emissions, in access of the threshold limit values caused by the wind from open storage areas, yards, roads, etc., within lot lines shall be kept to a minimum by appropriate landscaping, paving, oiling, wetting, and other means, or shall be eliminated.
For the purpose of determining the density or equivalent opacity of smoke, the Ringelmann chart as adopted and published by the United States bureau of mines in circular no. 8333 shall be used.
No industrial operation shall cause or allow to be emitted into the open air from any process or control equipment or to pass any convenient measuring point in a breaching or stack, dust in the gases to exceed 0.85 pounds per thousand pounds of gases adjusted to twelve percent (12%) CO2 content for the products of combustion.
The emission, from all sources within any zoning lot, of particulate matter containing more than ten percent (10%) by weight of particles having a particulate diameter larger than forty four (44) microns is prohibited.
b. Permitted Smoke Emission: Within one thousand feet (1,000') of a residence or office or business zoning district boundary line the emission of smoke from any vent, stack, chimney, or combustion process shall not exceed a density or equivalent opacity no greater than Ringelmann no. 1.
Smoke in excess of Ringelmann no. 1, but not exceeding Ringelmann no. 2, shall be permitted for not more than three (3) minutes in any sixty (60) minute period. Smoke not exceeding Ringelmann no. 3 shall be permitted for five (5) minutes during any eight (8) hour period for purposes of fire cleaning only. Smoke in excess of Ringelmann no. 3 is prohibited.
4. Fire And Explosion Hazard Limitations: The following regulations supplement those pertinent requirements contained in the Mount Prospect fire prevention code and all other applicable fire and explosion ordinances:
a.

b. 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 the industrial districts, and provided the following conditions are met:
(1) 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 ordinances of this code.
(2) Unless otherwise provided in this chapter, 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.

When maximum permissible airborne concentrations of toxic materials allowed an industrial worker are not contained in the most recent list of "Threshold Limit Values" published by the American conference of governmental industrial hygienists, the applicant shall satisfy the health inspector that proposed levels will be safe to the general population.
6. Odorous Matter Limitations: The release of odorous matter from any industrial district across residence or business district boundary lines shall be so controlled that, at ground level or at habitable elevations, the concentration shall not exceed the odor threshold level. Further, the release of odorous matter across lot lines shall not become a nuisance or source of discomfort to neighboring uses.
7. Glare Limitations: In any industrial district, any operation or activity producing glare shall be so conducted that direct and indirect illumination from the sources of light shall not cause illumination in excess of one-half (0.5) of one foot-candle when measured at any residence or business district boundary line.
