      (1)   Noise.
         (a)   At any property line the sound pressure level of noise radiated from a permitted operation shall not exceed the values given in the table below.
         (b)   The sound pressure level shall be measured with a sound level meter and an associated octave band analyzer, both of which are manufactured to specifications published by the American Standard Specifications for an Octave Band Filter Set for the Analysis of Noise and Other Sounds, Z24.10-1953, American Standard Association, Inc., New York, New York.
         (c)   Measurements shall be made using the flat network of the sound level meter.

      (6)   Dust.
         (a)   Solid or liquid particles shall not be emitted at any point in concentrations exceeding 0.3 grains per cubic foot of the conveying gas or air.
         (b)   For measurements of the amount of particles in gases resulting from combustion, standard corrections shall be applied to a stack temperature of 500°F and 50% excess air.
      (7)   Fumes or gases.
         (a)   Fumes or gases shall not be emitted at any point in concentrations or amounts that are noxious, toxic or corrosive.
         (b)   The values given in the following tables in the Air Pollution Abatement Manual, Chapter 5, Physiological Effects, by the Manufacturing Chemists’ Association , Inc., Washington, D.C., are guides for determining permissible concentration or amounts:
            1.   Table 1 (Industrial Hygiene Standards - Maximum Allowable Concentration for 8-hour day, 5 days per week;
            2.   Table III (Odor Thresholds);
            3.   Table IV (Exposure to Substances Causing Pain in the Eyes); and

      (3)   Lighting.
         (a)   All sources of artificial light shall be so fixed, directed, designed or sized that the sum total of their illumination will not increase the level of illumination on any nearby residential property by more than 0.1 foot-candle in or within 25 feet of a dwelling nor more than 0.5 foot-candle on any other part of the property.
         (b)   Glare, whether direct or reflected, as differentiated from general illumination, shall not be visible from beyond the limits of the immediate site from which it originates.
