A.    Sanitary Sewers. Each use in a commercial park zoning district, with the exception of agriculture, shall be connected to the city’ s sanitary sewer system. All uses in the commercial park zoning districts shall conform to the laws, rules and regulations promulgated by the state of Illinois and federal agencies governing the pretreatment of waste streams prior to discharge into a publicly owned treatment works ("POTW").

    B.    Stormwater Management, Retention and Drainage. Any person, firm, corporation or other entity proposing to construct buildings or develop land within a commercial park zoning district must first comply with the stormwater management ordinance of the city, as amended. No building or construction permits shall be issued by the city and no final plat and no improvement plans for a real estate development in a commercial park zoning district shall be approved by the city until a stormwater management plan has been approved by the city engineer as meeting the requirements of the stormwater management ordinance, or compliance is waived in accordance with and pursuant to such ordinance.

    C.    Noise. The following minimum noise standards must be complied with:

    1.    For purposes of measuring the intensity of frequency of sound, the sound level meter, the octave band analyzer, and the impact noise analyzer shall be employed. The "C" network and the "slow" meter response of the sound level meter shall be used. Sounds of short duration, such as forge hammers, punch presses, etc., which cannot be measured accurately with the sound level meter, shall be measured with the impact analyzer as manufactured by the General Radio Company, or its equivalent, in order to determine the peak value of the impact.

    2.    The sound pressure level resulting from any activity, whether open or enclosed, shall not exceed, at any point on or beyond any lot line, the maximum permitted decibel levels for the octave band as set forth in the following table:

20 -- 75        79

75 -- 100        74

150 - 300        66

300 - 600        59

600 -- 1,200        53

1,200 -- 2,400        47

2,400 -- 4,800        41

Above 4,800        39

    D.    Vibration. The following minimum vibration standards must be complied with:

    1.    No activity shall cause or create a steady state vibration at any point on any lot line, with a displacement in excess of the permitted steady state vibration displacement for the frequencies as set forth in the following table:

10 and below        .0008

10 -- 20        .0005

20 -- 30        .0003

30 -- 40        .0002

40 -- 50        .0001

50 -- 60        .0001

60 and over        .0001

    2.    No activity shall cause or create an impact vibration, at any point on any lot line, with a displacement in excess of the permitted impact vibration displacement for the frequencies as set forth in the following table:

10 and below        .0016

10 -- 20        .0010

20 -- 30        .0006

30 -- 40        .0004

40 -- 50        .0002

50 -- 60        .0002

60 and over        .0002

    E.    Smoke, Odorous Matter, Toxic Matter. The following minimum smoke, odorous matter, and toxic matter standards must be complied with:

    1.    The density of emission of smoke during normal operations shall not exceed Standard Smoke Chart No. 2, and the quantity of smoke shall not exceed a maximum of ten smoke units per hour per stack.

    2.    The maximum permitted emission of dust relating to combustion for indirect heating from any source shall not exceed the maximum number of pounds of dust per million British Thermal Units heat input per hour as follows: The maximum permitted emission shall be 0.50 pounds per minimum size plants producing a heat input of ten million or less British Thermal Units per hour and 0.15 for maximum size plants producing a heat input of ten thousand (10,000) million or more British Thermal Units per hour. All intermediate values shall be determined from a straight line plotted on log graph paper.

    3.    The emission into the atmosphere of process dust or other particulate matter which is unrelated to combustion for indirect heating or incineration shall not exceed 0.50 pounds per one hundred (100) pounds of process weight or fifty (50) pounds for one hundred thousand (100,000) pounds of process weight. All intermediate values shall be determined from a straight line plotted on log graph paper.

    4.    The emission of odorous matter in such quantities as to be readily detectable at any point along lot lines or to produce a public nuisance or hazard beyond lot lanes is prohibited.

    5.    The emission of toxic or noxious matter, whether solid, liquid or gaseous shall be so controlled that no concentration at or beyond lot lines shall be detrimental to or endanger the public health, safety, comfort, any other aspects of the general welfare, or cause damage or injury to property.

    F.    Radioactive Materials. Activities which require radioactive materials in any form are prohibited.

    G.    Fire, Explosives, Humidity, Heat and Glare. The following minimum fire, explosive hazards, humidity, heat and glare standards must be complied with:

    1.    For the purpose of this section, materials are divided into four classifications or ratings based on the degree of fire and explosive hazard. The rating of liquids is established by specified open cup flash points.

    a.    Class I includes slow burning to moderate burning materials. This shall include all liquids with an open cup flash point of one hundred eighty-two (182) degrees Fahrenheit or more.

    b.    Class II includes free burning to intense burning materials. This shall include all liquids with an open cup flash point between one hundred (100) degrees Fahrenheit and one hundred eighty-two (182) degrees Fahrenheit.

    c.    Class III includes materials which produce flammable or explosive vapors or gases under ordinary weather temperature. This shall include all liquids with an open cup flash point of less than one hundred (100) degrees Fahrenheit.

    d.    Class IV includes materials which decompose by detonation, including but not limited to all primary explosives.

    2.    Class I materials as defined above may be stored, manufactured, or utilized in manufacturing processes or other production.

    3.    Class II materials may be stored, manufactured, or utilized in manufacturing processes or other production only in accordance with the following provisions:

    a.    Such storage, manufacture or utilization shall be carried on only within buildings or other structures which are completely enclosed by incombustible exterior walls.

    b.    Such buildings or other structures shall either be set back at least forty (40) feet from any lot lines, or in lieu thereof, all such buildings shall be protected throughout by any automatic fire extinguishing system.

    4.    Any activity producing excessive humidity in the form of steam or moist air, or producing intense heat or glare, shall be carried out within an enclosure and in such a manner as not to be perceptible at or beyond any lot line. (Ord. 1742 § 1 (part), 1999)
