This ordinance permits specific uses in a specific district, and these performance standards are designed to limit, restrict, and prohibit the effects of those uses outside their premises or district. No structure, land, or water shall hereafter be used except in compliance with their district regulations and with the following performance standards.

A.

The following uses are prohibited in all manufacturing districts whether or not they meet the performance standards: Crematories; fireworks or explosive manufacture or storage; dumping, fertilizer plants, reduction or other processing of garbage, dead animals, offal or refuse, except as customarily incidental to a permitted principal use; stockyard or slaughter of animals or fowls; tanning, curing, or storage of rawhides or skins; junk shop; junkyards or automobile wrecking yards.

B.

No activities involving the storage, utilization, or manufacture of materials or products which decompose by detonation shall be permitted, except that those activities customarily incidental to the operation of permitted principal uses may be permitted by a variation by the board of zoning appeals. Such materials shall be stored, utilized, and manufactured in accordance with the applicable rules and regulations of the county and the State of Illinois.

C.

Such materials shall include but shall not be confined to all primary explosives such as lead acid, lead styphnate, fulminates, and tetracens; all high explosives such as TNT, RDX, HMX, PETN, and picric acid; propellants and components thereof, such as dry nitrocellulose, black powder, boron hydrides, hydrazine, and its derivatives; pyrotechnics and fireworks such as magnesium powder, potassium chlorate, and potassium nitrate; blasting explosives such as dynamite and nitroglycerine; unstable organic compounds such as acetylides, tetrazoles, and ozonides; strong oxidizing agents such as liquid oxygen, perchloric acid, perchlorates, 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.

No activity shall emit any fly ash, chaffing dust, fumes, vapors, mists, or gases in such quantities as to cause soiling or danger to the health of persons, animals, vegetation, or other forms of property. No activity shall emit any liquid or solid particles in concentrations exceeding 0.3 grain per cubic foot of the conveying gas nor any color visible smoke equal to or darker than No. 2 on the Ringelmann Chart described in the United States Bureau of Mines Information Circular 7718; except for not more than four minutes during any six-hour period each stack or chimney, in an M-2 General Manufacturing District, may emit smoke of Ringelmann No. 3. No activity shall emit more than ten smoke units per hour per stack or chimney except that once during any six-hour period each stack or chimney, in an M-2 General Manufacturing District, may emit up to 20 smoke units when blowing soot or cleaning fires.

All activities involving the manufacturing, utilization, processing, or storage of inflammable and explosive materials shall be provided with adequate safety devices against the hazard of fire and explosion and with adequate firefighting and fire-suppression equipment and devices that are standard in the industry. All materials that range from active to intense burning shall be manufactured, utilized, processed, and stored only in completely enclosed buildings which have incombustible exterior walls and an automatic fire-extinguishing system. The aboveground storage capacity of materials that produce flammable or explosive vapors shall not exceed the following:

No activity shall emit glare or heat that is visible or measurable outside its premises except activities in the M-2 General Manufacturing District which may emit direct or sky-reflected glare which shall not be visible outside their district. All operations producing intense glare or heat shall be conducted within a completely enclosed building. Exposed sources of light shall be shielded so as not to be visible outside their premises.

No activity shall discharge at any point onto any land or into any water or public sewer any materials of such nature, quantity, noxiousness, toxicity, or temperature which can contaminate, pollute, or harm the quantity or quality of any water supply, can cause the emission of dangerous or offensive elements, can overload the existing municipal utilities, or can injure or damage persons or property.

No activity in an M-2 General Manufacturing District shall produce a sound level outside the district boundary that exceeds the following sound level measured by a sound level meter and associated octave band filter:

No other activity in any other district shall produce a sound level outside its premises that exceeds the following:

All noise shall be so muffled or otherwise controlled as not to become objectionable due to intermittence, duration, beat frequency, impulse character, periodic character or shrillness.

No activity shall emit any odorous matter of such nature or quantity as to be offensive, obnoxious, or unhealthful outside their premises. The guide for determining odor measurement and control shall be chapter 13, Air Pollution Abatement Manual 1960, prepared by the Manufacturing Chemists' Association, Inc., Washington, D.C.

No activity shall emit radioactivity or electrical disturbances outside its premises that are dangerous or adversely affect the neighboring premises.

No activity in any district except the M-2 Manufacturing District shall emit vibrations which are discernible without instruments outside its premises. No activity in an M-2 Manufacturing District shall emit vibrations which exceed the following displacement measured with a three-component measuring system:

A.

No use permitted in any manufacturing district shall be issued a zoning permit until a certified statement has been signed by a qualified professional engineer and a responsible agent for the proposed use stating that all provisions of the performance standards set forth in this article will be met.

B.

No use permitted in any manufacturing district shall be issued a certificate of compliance until all provisions of this ordinance have been complied with and tests on operating equipment made under normal operating conditions have been performed indicating full compliance with all performance standards. Such statement shall be certified and signed by a qualified professional engineer and a responsible agent for the operating use.
