(A) In addition to the uses shown on the Land Use Chart for nonresidential uses, retail and service establishments essential to the operation of a Planned Industrial District and providing goods and services which are primarily for the use of persons employed in this district may be allowed.
(D) The Council may require the owner or operator of any permitted use to have made such investigation or test as may be required to show adherence to the performance standards hereinafter enumerated.
(2) Storage of materials. Unless authorized by a conditional or interim use permit or building permit:
(a) Open storage of materials in any required front or side yard is prohibited; or
(b) Other outside storage shall be located or screened so as not to be visible from any residence district or from any public street or highway.
(3) Noise. At any property line the sound pressure level of noise radiated from an industrial operation shall not exceed the values given in the Land Use Chart set out in the appendix to this chapter. 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 Standards Association, Inc. of New York, New York. Measurements shall be made using the flat network of the sound level meter.

Frequency Band Cycles per Second | Maximum Permitted Sound Level (decibels) | |
Over 4800 | 32 | |
(4) Odors. No odors shall be detectable beyond the limits of the property.
(5) Exterior lighting/glare. Any lights used for exterior illumination shall direct light away from adjoining property. Glare, whether direct or reflected, such as from floodlights, spotlights, or high-temperature processing, and as differentiated from general illumination, shall not be visible beyond the limits of the property.
(6) Vibration. No vibration shall be discernible to the human sense of feeling for an accumulated total of 3 or more minutes during any hour at any property line.
(7) Smoke. The Ringelmann Smoke Chart, published by the United States Bureau of Mines, shall be used for measuring smoke at the point of emission. Smoke not darker or more opaque than No. 4 on the Chart may be emitted, except that smoke darker or more opaque than No. 2 on the Chart may not be emitted for periods longer than 4 minutes in any 30 minutes. These provisions, applicable to visible gray smoke, shall also apply to visible smoke of a different color but an equivalent opacity.
(8) Dust. 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. For measurement of the amount of particles in gases resulting from combustion, standard corrections shall be applied to a stack temperature of 500 degrees Fahrenheit and 50% excess air.
(9) Fumes or gases. Fumes or gases shall not be emitted at any point in concentrations or amounts that are noxious, toxic or corrosive. The values given in Table I (Industrial Hygiene Standards - Maximum Allowable Concentration for Eight Hour Day, Five Days Per Week), Table III (Odor Thresholds), Table IV (Exposure to Substances Causing Pain in the Eyes), and Table I (Exposure to Substances Causing Injury to Vegetation) in the latest revision of Chapter 5, “Physiological Effects,” that contains such Tables, in the “Air Pollution Abatement Manual,” by the Manufacturing Chemists’ Association, Inc., Washington, D.C., are established as guides for the determination of permissible concentration or amounts. Detailed plans for the elimination of fumes or gases may be required before the issuance of a building permit.
