(A) Noise. Noise shall be measured on any property line of the tract on which the operation is located. Noise shall be muffled so as not to become objectionable due to intermittence, beat frequency, shrillness, or intensity. At the property line, the sound pressure level of noise radiated from a facility shall not exceed the values given in Table I below. The sound pressure level shall be measured with a sound level meter and on an associated octave band analyzer, both of which are manufactured according to current specifications prescribed by the American National Standards Institute. Measurement shall be made using the flat network of the sound level meter.

Octave Band Frequency (Cycles per Second) | Maximum Decibel Level |
20 to 75 | 65 |
75 to 150 | 60 |
150 to 300 | 55 |
300 to 600 | 46 |
600 to 1,200 | 40 |
1,200 to 2,400 | 34 |
2,400 to 4,800 | 31 |
4,800 or over | 28 |
(B) Air pollution. State emission standards shall be met by all possible sources of air pollution. In any case, there shall not be discharged from any sources whatsoever such quantities of air contaminants, smoke or detriment, nuisance, or annoyance to any considerable number of persons or to the public in general to endanger the comfort, health, or safety of any such considerable number of persons or have a natural tendency to cause injury or damage to business, vegetation, or property.
(C) Vibration. No activity or operation shall at any time cause earth vibrations perceptible beyond the limits of the immediate site on which the operation is located.
(D) Dust and dirt. Solid or liquid particulates shall not be emitted at any point in concentrations or amounts exceeding limitations established in the latest revision of federal and state regulations.
(E) Smoke. Smoke shall not be emitted from any source with opacity or frequency exceeding limitation in federal or state regulations, the latest revision of which is hereby incorporated by reference. All open burning is prohibited or must be conducted in conformance with applicable federal and state regulations. The latest revision of which is hereby incorporated by reference.
(F) Odor. No activity or operation shall cause at any time the discharge of toxic, noxious, or odorous matter beyond the limits of the immediate site where it is located in such concentrations as to be detrimental to or endanger the public health, welfare, comfort, or safety or cause injury to property or business.
(G) Glare. Glare, whether direct or reflected, such as from spotlights or high temperature processes, and as differentiated from general illumination, shall not be visible beyond the limits of the immediate site from which it originates.
(H) Wastes. All solid waste material debris, refuse, or garbage shall be kept within a completely enclosed building or proper contained in a closed container designed for such purpose.
(I) Odor. The emission of odorous matter in such quantities as to be readily detectable at any point along lot lines or to produce a public nuisance or hazard beyond lot lines is prohibited.
(J) Sewage and liquid wastes. No operation shall be carried on which involves the discharge into a sewer, watercourse, river, or the ground of liquid wastes of any radio-active nature, or liquid wastes of chemical nature, which are detrimental to normal sewage plant operations or corrosive or damaging to sewer pipes and installations.
(K) Fire hazard. All flammable substances involved in any activity or use shall be handled in conformance with the standard of the National Board of Fire Underwriters and any additional regulations that may from time to time be adopted by the City Council.
(L) Physical appearance. All operations shall be carried on within an enclosed building except that new or operable equipment and waste materials stored in enclosed containers, not readily visible from the street, may be displayed or stored in the open.
(M) Tests; owner. The owner or operator of any permitted use shall be required to show compliance with the performance standards set forth above. In cases where compliance cannot be demonstrated to the satisfaction of the City Council or where reasonable doubt exists, the City Council may require the owner or operator to have investigations or tests made by an independent testing organization. Costs of such investigations or tests shall be paid by the owner or operator. In all cases the tests must comply with requirements of federal and state regulations.
(N) Tests; city. The procedure above stated shall not preclude the city from making any tests and investigations it finds appropriate to determine compliance with these performance standards.
