(A) Smoke - a general industrial use shall meet such requirements as are imposed by the Illinois Environmental Protection Agency or other applicable state or federal law.
(B) Odor - No general industrial use may release an odor that is detectable at the lot line.
(C) TOXIC MATERIALS - For general industrial use, the emission of toxic and noxious materials may not produce any concentration at a residence or business district boundary line exceeding 10 percent of the threshold limit values for toxic materials in industry as set forth in “Threshold Limit Values” for the current year, as adopted at the annual meeting of the American Conference of Governmental Industrial Hygienists.
(D) GLARE AND HEAT - No general industrial use may cause heat at the lot line so intense as to be a public nuisance or hazard. No such use may cause illumination at or beyond any residence district boundary in excess of 0.1 footcandle8. (For footnote (8), see footnote (2) in § 161.294.)
(E) PARTICULATE MATTER9. A general industrial use shall meet such requirements as are imposed by the Illinois Environmental Protection Agency or other applicable state or federal law. (For footnote (9), see footnote (3) in § 161.294.)
(F) VIBRATION - No general industrial: use may cause at any business district boundary continuous earthborne vibrations higher than the limits set forth in Column l of the following table. Nor may it cause at any residence or Mobile Home district boundary continuous earthborne vibrations higher than the limits set forth in column II.

(G) NOISE11 - At no boundary of a residence or business district may the sound pressure level of any general industrial use (except for background noises produced by sources not under control of this ordinance, such as the operation of motor vehicles or other transportation facilities) exceed the following decibel limits. (For footnote (11), see footnote (5) in § 161.294.)

The prescribed limits of column I apply between 8:00 a.m. and 6:00 p.m. At other times, the allowable levels in each octave band are each reduced by 6 decibels. | |||
Sound levels shall be measured with a sound level meter and associated octave band filter, manufactured and calibrated according to standards prescribed by the American Standards Association. Measurements shall be made using the Flat C network of the sound level meter and the fast meter movement of the octave band analyzer. Impulsive noises are subject to the performance standards prescribed by this section if they cause rapid fluctuations of the needle of the sound level meter with a variation of no more than plus or minus 2 decibels. Noises incapable of being so measured, such as irregular and intermittent noises, shall be controlled so as not to be a nuisance to adjacent uses.

(H) FIRE HAZARDS12 -
(1) Solid substances ranging from free or active burning to intense burning may be stored, used, or manufactured only within completely enclosed buildings having incombustible exterior walls and protected throughout by an automatic fire extinguishing system.
(2) The storage utilization, or manufacturing of flammable liquids or materials which produce flammable vapors or gases shall be permitted in accordance with the Rules and Regulations of the State Fire Marshal. A certificate of compliance, issued by the State Fire Marshal’s Office, stating that the plans and specifications for a light or general industrial use comply with the Rules and Regulations of the State Fire Marshal shall accompany the application for certificate of zoning compliance.
(3) For footnote (12), see footnote (6) in § 161.294.
(I) DETONATION MATERIALS - No activity involving the storage, use, or manufacturing of materials that decompose by detonation may be carried on except in accordance with the rules issued by the State Fire Marshal. These materials include primary explosives such as lead azide, lead styphnate, fulminates, and tetracene; high explosives such as TNT, RDX, HMX, PETN, and picric acid; propellants and their components, such as nitrocellulose, black powder, boron hydrides, hydrazine and its derivatives; pyrotechnics and fire works such as magnesium powder, potassium chlorate, and potassium nitrate; blasting explosives such as dynamite and nitroglycerine, unstable organic compounds such as acetylines, tetrazoles, and ozonides; strong oxidizing agents such as liquid oxygen, perchloric acid, perchlorics, chlorates, and hydrogen peroxide in concentrations greater than 35 percent; and nuclear fuels, fissionable materials and products, and reactor elements such as Uranium 235 and Plutonium 239.
(J) EXCEPTIONS -
(1) These performance standards do not apply to: Site preparation or construction, maintenance, repair, alteration, or improvement of buildings, structures, equipment or other improvements on or within the lot line;
(2) The operation of motor vehicles or other facilities for the transportation of personnel, materials, or products; Conditions beyond the control of the user such as fire, explosion, accident, failure, or breakdown;
(3) Safety or emergency warning signals or alarms necessary for the protection of life, limb or property;
(4) or processes for which there is no known means of control.
(5) Research shall be promptly conducted to discover methods of control leading to the installation of protective equipment.
