It shall be unlawful to carry on or permit any activity or operation or use of land, building or equipment within the I-1, I-2, C-1 and C-2 Districts that produces irritants to the sensory perceptions greater than the measures herein established that are hereby determined to be the maximum permissible hazards to humans or human activities.
(A) Sound. The emission of measurable noises from the premises shall not exceed 65 decibels as measured at the boundary property lines; except that, where normal street traffic noises exceed such level, the measurable noise emanating from the premises may equal, but not exceed such traffic noise. Within industrial districts, sound levels not exceeding 70 decibels may be permitted. In addition, objectionable sounds of any intermittent nature, or characterized by high frequencies even if falling below the aforementioned decibel reading shall be controlled so as not to create a nuisance or hazard to adjacent properties. Above decibel rates shall refer to the commonly called A-scale.
(B) Vibration. All machinery shall be so mounted and operated as to prevent transmission of ground vibration exceeding a displacement of three-thousandths of one inch measured at any lot line of its source.
(C) Odor. The emission of noxious, odorous matter in such quantities as to be readily detectable at any point along lot lines, when diluted in the ratio of one volume of odorous air to four or more volumes of clear air or as to produce a public nuisance or hazard beyond lot lines, is prohibited.
(D) Toxic gases. The escape of, or emission of any gas that is injurious or destructive or explosive shall be unlawful and may be summarily caused to be abated.
(E) Glare and heat. Any operation producing intense glare or heat shall be performed within an enclosure so as to completely obscure and shield such operation from direct view from any point along the lot line, except during the period of construction of the facilities to be used and occupied.
(F) Light. All lighting shall be arranged to reflect light away from adjoining residential zones or uses.
(G) Radioactive materials. Radioactive materials shall not be emitted so as to be unsafe to human health or life.
(H) Electromagnetic radiation. The rules and regulations of the Federal Communications Commission, as amended with respect to the propagation and dissemination of electromagnetic radiation must be followed and are hereby made a part of this chapter.
(I) Drifted and blown material. The drifting or airborne transmission beyond the lot line of soot, particles or debris from any stockpile shall be unlawful and may be summarily caused to be abated.
(J) Smoke, dust, dirt and fly ash.
(1) It shall be unlawful to discharge into the atmosphere from any single source of emission whatsoever any air contaminator for a period or periods aggregating more than two minutes in any one-half hour that is:
(a) As dark or darker in shade as that designated as No. 2 on the Ringelmann Chart as published by the United States Bureau of Mines and that is hereby made a part of this chapter. The Umbrascope readings of smoke densities, however, may be used when correlated with the Ringelmann Chart; and
(b) Of such opacity as to obscure an observer’s view to a degree equal to or greater than the smoke described in division (J)(1)(a) above, except when the emission consists of only water vapor.
(2) The quantity of gas-borne or air-borne solids shall not exceed two-tenths grains per cubic foot of the carrying medium at a temperature of 500°F.
(K) Liquid wastes. No discharge shall be permitted at any point into any private sewage disposal system, or street, or into the ground of any materials in such a way or of such nature or temperature as can contaminate any water supply or otherwise cause the emission of dangerous or objectionable elements, except when in accord with water quality standards of the state’s Water Resources Commission, adopted by state legislature and administered by the state’s Department of Natural Resources; and with the standards of such other state commissions having jurisdiction thereof.
