      3.   Smoke And Particulate Matter: The emission of smoke or particulate matter in such manner or quantity as to endanger or be detrimental to the public health, safety, comfort or welfare is hereby declared to be a public nuisance and shall not be permitted in the manufacturing districts.
   For the purpose of grading the density or equivalent opacity of smoke, the Ringelmann Chart described in the U.S. Bureau of Mines Information Circular 6888 shall be employed. The emission of smoke or particulate matter of a density or equivalent opacity greater than No. 2 on the Ringelmann Chart is prohibited at all times except as otherwise provided hereinafter.
   Dust and other types of air pollution borne by the wind from such sources as storage areas, yards, roads and the like within lot boundaries shall be kept to a minimum by appropriate landscaping, paving, oiling, fencing, wetting or other acceptable means.
   The open burning of refuse, paint, oil, debris and any other combustible material is prohibited in all manufacturing districts.
   No operation shall cause or allow to be emitted into the open air from any process or control equipment or to pass any convenient measuring point in a breaching or stack, particulate matter in the gases that exceeds six-tenths (0.60) pounds per thousand pounds of gases during any one hour.
   Particulate matter loadings in pounds per acre described below shall be determined by selecting a continuous four (4) hour period which will result in the highest average emission rate.
         a.   M1 Manufacturing District: The emission of smoke having a density or equivalent opacity in excess of Ringelmann No. 1 is prohibited. However, for two (2) minutes in any four (4) hour period, smoke up to and including Ringelmann No. 2 shall be permitted.
   The rate of emission of particulate matter from all vents and stacks within the boundaries of any lot shall not exceed five-tenths (0.5) of a pound per acre of lot area per hour.
         b.   M2 Manufacturing District: The emission of smoke having a density or equivalent opacity in excess of Ringelmann No. 2 is prohibited. However, for two (2) minutes in any four (4) hour period, smoke up to and including Ringelmann No. 3 shall be permitted.
   The rate of emission of particulate matter from all stacks and vents within the boundaries of any lot shall not exceed three (3) pounds per acre of lot area per hour.
      4.   Toxic Matter:
      M1 And M2 Manufacturing Districts: The release of airborne toxic matter (including radioactive matter) shall not exceed one-thirtieth (1/30) of the maximum permissible concentration allowed an industrial worker when measured by any point beyond the lot line, either at ground level or habitable elevation, whichever is more restrictive. Concentrations shall be measured and calculated as the highest average that will occur over a continuous twenty four (24) hour period.
   If a toxic substance is not contained in the most recent listing of threshold limit values published by the American Conference of Governmental Industrial Hygienists, the applicant shall satisfy the Grundy County Health Department that the proposed levels will be safe and not detrimental to the public health or injurious to plant and animal life.
      5.   Odorous Matter: The release of materials capable of becoming odorous, either by bacterial decomposition or chemical reaction, shall meet the standards of the district in which the odor is created.
         a.   M1 Manufacturing District: When odorous matter is released from any operation, activity or use in the M1 Manufacturing District, the concentration of such odorous materials shall not exceed the odor threshold when measured beyond the lot line, either at ground level or habitable elevation.
         b.   M2 Manufacturing District: When odorous matter is released from any operation, activity or use in the M2 District, the concentration of such odorous materials shall not exceed the odor threshold when measured beyond the M2 District boundary line.
      6.   Fire And Explosion Hazards: All flammable solid, liquid and gaseous substances shall be manufactured, stored and utilized in accordance with all applicable codes.
   In all manufacturing districts the storage, utilization or manufacture of solid materials or products ranging from incombustible to moderate burning is permitted.
