A. General: Any use established in the M1 and M2 districts after the effective date of this title shall be so operated as to comply with the performance standards governing: 1) noise; 2) vibration; 3) smoke and particulate matter; 4) toxic matter; 5) noxious and odorous matter; 6) fire and explosive hazards; and 7) glare and heat, set forth hereinafter for the district in which such use shall be located. No use already established shall conflict with, or further conflict with, the applicable performance standards established hereinafter for the district in which such use is located.
1. 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. The flat network and the slow meter response shall be used. Sounds of short duration, as from forge hammers, punch presses, and the like, which cannot be measured accurately with the sound level meter, shall be measured with the impact noise analyzer as manufactured by the General Radio Company or its equivalent in order to determine the peak value of the impact. For sounds so measured, the peak values shall not exceed by six (6) decibels the values given in subsection B2 of this section.
2. At no point on the boundary of a residence, business or M1 manufacturing district shall the sound pressure level of any operation or plant (other than background noises not directly under the control of the manufacturer) exceed the decibel limits in the octave bands designated below.
C. Vibrations: No industrial operation or activity (except those not under the direct control of the manufacturer) shall cause at any time ground transmitted vibrations in excess of the limits set forth below. Vibrations shall be measured at any point along a residence district boundary line with a three (3) component measuring instrument approved by national recognized standards, and shall be expressed as displacement in inches.

D. Smoke And Particulate Matter:
1. Any use already established on the effective date of this title shall be permitted to be altered, enlarged, expanded, or modified, provided that new sources of smoke and/or particulate matter conform to the performance standards established hereinafter for the district in which such use is located. The total emission weight of particulate matter from all sources within the boundaries of the lot shall not exceed the net amount permitted in the district in which the use is located after such alteration, enlargement, expansion, or modification.
2. For the purpose of grading the density of smoke, the Ringelmann Chart, published and used by the United States Bureau of Mines, shall be employed. The emission of smoke or particulate matter of a density greater than No. 2 on the Ringelmann Chart is prohibited at all times, except as otherwise provided hereinafter.
3. The emission, from all sources within any lot area, of particulate matter containing more than five percent (5%) by weight of particles having a particle diameter larger than forty four (44) microns is prohibited.
4. Dust and other types of air pollution, borne by the wind from such sources as storage areas, yards, roads, and so forth within lot boundaries, 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 the weight limitations specified hereinafter for the district in which such use shall be located is prohibited.
a. The Ringelmann Chart is hereby adopted by reference and three (3) copies of said chart are on file in the office of the village clerk.
5. In the M1 district the following additional regulations shall apply:
a. The emission of more than twelve (12) smoke units per stack in any thirty (30) minute period is prohibited, including smoke in excess of Ringelmann No. 2. However, once during any three (3) hour period, each stack shall be permitted up to twenty (20) smoke units (not to exceed Ringelmann No. 3) in thirty (30) minutes for soot blowing and fire cleaning.
b. The rate of particulate matter emission from all sources within the boundaries of any lot shall not exceed a net figure of one pound per acre of lot area during any one hour period, after deducting from the gross hourly emission per acre the correction factor set forth in the following table:
Allowance For Height Of Emission*
*Interpolate for intermediate values not shown in table.
Determination of the total net rate of emission of particulate matter within the lot boundaries of any lot shall be made as follows:
(1) Determine the maximum emission in pounds per hour from each source of emission and divide this figure by the number of acres of lot area – thereby obtaining the gross hourly rate of emission in pounds per acre.
(2) From each gross hourly rate of emission derived in the above item, deduct the correction factor (interpolating as required) for height of emission set forth in the table – thereby obtaining the net rate of emission in pounds per acre per hour from each source of emission.
(3) Add together the individual net rates of emission derived in the above item, to obtain the total net rate of emission from all sources of emission within the boundaries of the lot – such total shall not exceed one pound per acre of lot area during any one hour.
6. In the M2 district the following additional regulations shall apply:
a. The emission of more than sixteen (16) smoke units per stack in any thirty (30) minute period is prohibited, including smoke in excess of Ringelmann No. 2. However, once during any two (2) hour period, each stack shall be permitted up to twenty four (24) smoke units (not to exceed Ringelmann No. 3) in thirty (30) minutes for soot blowing and fire cleaning.
b. The rate of particulate matter emission from all sources within the boundaries of any lot shall not exceed a net figure of eight (8) pounds per acre during any one hour, after deducting from the gross hourly emission per acre the correction factor set forth in the following table:
Allowance For Height Of Emission*
*Interpolate for intermediate values not shown in table.
Determination of the total net rate of emission of particulate matter within the boundaries of any lot shall be made as follows:
(1) Determine the maximum emission in pounds per hour from each source of emission and divide this figure by the number of acres of lot area, thereby obtaining the gross hourly rate of emission in pounds per acre.
(2) From each gross hourly rate of emission derived in the above item, deduct the correction factor (interpolating as required) for height of emission set forth in the table, thereby obtaining the net rate of emission pounds per acre per hour from each source of emission.
(3) Add together the individual net rate of emission derived in the above item, to obtain the total net rate of emission from all sources of emission within the boundaries of the lot; such total shall not exceed four pounds per acre of lot area during any one hour.
E. Toxic Matter: No activity or operation shall cause, at any time, the discharge of toxic or noxious matter across lot lines in such concentrations as to be detrimental to or endanger the public health, safety, comfort, or welfare, or cause injury or damage to property or business.
F. Noxious And Odorous Matter:
1. M1 Districts: No activity or operations shall cause at any time the discharge of matter across lot lines in such concentration as to be noxious. The emission of odorous matter in such quantities as to be readily detectable as an odor at any point along a lot line is prohibited.
2. M2 Districts: No activity or operation shall cause at any time the discharge of matter across lot lines in such concentration as to be noxious.
