10-5-1: INDUSTRIAL PERFORMANCE STANDARDS:
It is the purpose of this chapter to establish regulations and standards for the installation and operation of industrial uses, based upon consideration of the objectionable characteristics of such uses and the zones in which they are permitted.
Further, this is intended to prescribe procedures and methods of measurement of industrial characteristics subject to such standards.
Any use permitted in the OR, LI zones or any overlay district, whether such use is permitted as a principal use or as an accessory use, shall be subject to these standards:
   A.   Permit Procedure: Before the zoning officer issues a building permit for a use in any OR or LI zone, the applicant shall furnish the zoning officer sufficient information to enable the zoning officer to assure himself that all performance can and will be complied with at all times. The zoning officer, in order to determine whether or not the applicant will meet such standards, may require the applicant to submit the following information:
      1.   A plot plan showing the location of all present and proposed structures, drives, parking lots, waste disposal areas, bulk storage areas, streets, streams or other significant features on or within two hundred feet (200') of the proposed site.
      2.   A description of the activity to be conducted regarding waste products, external effects or other conditions which are regulated herein; provided, however, that the applicant shall not be required to reveal any trade secrets or sufficient detail with regard to a process which would cause any secret process or manufacturing procedure for a closely guarded proprietary compound or product to become public knowledge and be available to competitors.
      3.   The type and location of abatement devices to control, or recording instruments to measure, conformance with required standards, not including devices and instruments which are inherent in the manufacturing process.
      4.   Such other data and certification as may reasonably be required by the zoning officer to reach a determination.
All information and evidence submitted in applications to indicate conformity to performance standards shall constitute a certification and an agreement on the part of the applicant that the proposed use can and will conform to such standards at all times.
   B.   Performance Standards: In the OR and LI zones, the following regulations shall apply:
      1.   Noise:
         a.   Permitted Noise Levels: At no point on or beyond the boundary of any lot which abuts a lot in the same zone shall the sound pressure level resulting from any use or activity, whether open or enclosed, exceed the maximum permitted decibel levels for the designated octave band as set forth in table 3, section 10-5-14 of this chapter.
The sound pressure level resulting from any use or activity which abuts any other zone shall not exceed the maximum permitted level for the octave band as provided in Table 3, Section 10-5-14 of this Chapter.
         b.   Method Of Measurement: 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 and "slow" meter response of the sound level meter. Impulsive type noises shall be subject to the performance standards if those noises are 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 capable of being so measured, but objectionable because of intermittence, beat, frequency or shrillness shall be controlled so as not to become a nuisance to adjacent uses.
         c.   Exception: Nothing in this Chapter shall apply to noises not directly under the control of the property user; noises resulting from the construction and maintenance of buildings and facilities including site preparation; noises of safety signals or warning devices and noises of railroad or trucking equipment.
      2.   Vibration: Steady-state vibrations, for the purpose of this Title, are vibrations which are continuous or vibrations in discrete pulses more frequent than one hundred (100) per minute. Discrete pulses which do not exceed one hundred (100) impulses per minute shall not cause displacement in excess of twice the values established in Table 4, Section 10-5-14 of this Chapter. Impact vibrations shall mean vibrations occurring in discrete pulses separated by an interval of at least one minute and numbering no more than eight (8) per twenty four (24) hour period.
         a.   Permitted Vibration Displacements: At no point on or beyond the boundary of any lot shall the ground-transmitted steady-state or impact vibration caused by any use or activity (except those not directly under the control of the property uses) exceed the limits as established in Tables 4 and 5, Section 10-5-14 of this Chapter, for the OR and LI Zones.
         b.   Method Of Measurement: For the purpose of measuring vibrations, a three (3) component measuring system shall be used. A three (3) component measuring system denotes instrumentation which can measure earthborn vibrations in three (3) directions, each of which occurs at right angles to the other two (2).
      3.   Smoke And Particulate Matter: The emission, from all sources within any lot, or particulate matter containing more than five percent (5%) by weight of particles having a particle diameter larger than forty four (44) microns is prohibited. Dust and other types of air pollution borne by the wind from such sources as storage areas, yards and roads within the boundaries of any lot shall be kept to a minimum by appropriate landscaping, paving, oiling or other acceptable means. Emission of particulate matter from such sources in excess of weight limitations specified herein is prohibited. The emission of smoke or particulate matter of a density equal to, or greater than No. 2 on the Ringelmann Chart is prohibited at all times except as otherwise provided herein.
         a.   Smoke Emission: In the OR and LI Zones, the emission of more than twelve (12) smoke units per stack in any one hour period is prohibited; however, once during any six (6) hour period each stack shall be permitted up to twelve (12) additional units in a fifteen (15) minute period for soot blowing and fire cleaning. Only during such fifteen (15) minute periods shall smoke of a density equal to, but not exceeding, Ringelmann No. 3 be permitted and then only for fire cleaning and for not more than four (4) minutes per period.
         b.   Particulate Matter Emission: The rate of emission of particulate matter from all sources within the boundaries of any lot shall not exceed the rate established in Table 6, Section 10-5-14 of this Chapter.
         c.   Methods Of Measurement:
            (1)   Smoke: For the purpose of grading the density of emission of smoke, the Ringelmann Chart, published and used by the United States Bureau of Mines, shall be employed. For the purpose of determining smoke units, the Ringelmann density reading shall be made at least every minute during the period of observation. Each reading (Ringelmann number) shall be multiplied by the time in minutes for which it is observed and the products added together to determine the total number of smoke units observed during the total period of observation.
            (2)   Particulate Matter: The total net rate of emission of particulate matter within the boundaries of any lot shall be determined as follows:
Determine the maximum emission in pounds per hour from each source of emission and divide by the number of acres of lot areas, thereby obtaining the hourly rate of emission in pounds per acre. Add together the individual rates of emission as derived above to obtain the total rate of emission from all sources within the boundaries of the lot. It is this total that shall not exceed the rate established in table 6, section 10-5-14 of this chapter.
      4.   Odors: No continuous, frequent or repetitive emission of odors or odor causing substances which would be offensive beyond any property lines of any industrial use will be permitted. An odor emitted no more than fifteen (15) minutes in any one day shall not be deemed as continuous, frequent or repetitive within the meaning of these regulations. The existence of an odor shall be presumed when analysis by a competent technician demonstrates that a discernable odor is being emitted. Any process which may involve the creation or emission of any odors shall be provided with a primary and a secondary safeguard system so that control will be maintained if the primary safeguard system fails. The rules and regulations of the Illinois air pollution control board shall be complied with.
      5.   Radiation Hazards: The handling of radioactive materials, the discharge of such materials into air and water and the disposal of radioactive wastes shall be in conformance with:
         a.   The applicable regulations of the atomic energy commission; and
         b.   The applicable regulations of any instrumentality of the state.
      6.   Fire And Explosive Hazards:
         a.   The provisions of 225 Illinois Compiled Statutes 210/1001 et seq., shall be complied with and no explosives shall be stored, used or manufactured without first submitting to the zoning officer a certificate of compliance from the Illinois department of mines and minerals.
         b.   No gasoline or other inflammables or explosives shall be stored unless the location, plans and construction conform to the laws and regulations of the state of Illinois fire marshal's office.
      7.   Glare And Heat: Every use and activity shall be so operated that it does not emit heat or heated air beyond the boundary of the lot on which it is located. No direct or sky reflected flare shall emanate from any use or activity so as to be visible at any point on or beyond the boundary of the lot on which such use or activity is located. This restriction shall not apply to signs otherwise permitted by the provisions of this title or other applicable ordinances, nor to activities of a temporary or of an emergency nature. Night lighting necessary for safety and the protection of property is excluded from this provision.
      8.   Electromagnetic Interference: There shall be no electromagnetic interferences that adversely affect the operation of any equipment other than that belonging to the creator of such interference or that does not conform to the regulations of the federal communications commissions.
   C.   Enforcement: The zoning officer shall enforce the provisions of this chapter. Upon confirmation of a violation, enforcement and penalty provisions of section 10-7-5 of this title shall prevail. In addition, the village may require the installation, maintenance and operation by the offending industry of continuous measuring or recording instruments to demonstrate the operation and to ensure continuous compliance with the prescribed standards.
