17.60.000 Purpose.
The purpose of this chapter is to impose reasonable limits on the amount of noise, dust, vibration and other similar emissions produced by a use which are evident at the exterior boundaries of the site of the use.
17.60.010 Standards.
A. Noise. Noise emanating from any use shall be muffled so as to not become objectionable due to intermittent beat, frequency or shrillness, and where a use is within or adjoins a residential district, the noise loudness measured at the boundary line shall not exceed 45 decibels between the hours of 11:30 p.m. and 6:00 a.m., and 60 decibels at other hours.
B. Lighting. Lighting shall not be used in such a manner that produces glare on public streets, highways and neighboring property. Arc welding, acetylene torch cutting or similar processes shall be performed so as not to be seen from any point beyond the outside of the property.
C. Fire Hazards. In terms of fire and safety hazards, the storage and handling of flammable liquids, liquefied petroleum, gases and explosives shall comply with rules and regulations falling under the jurisdiction of the city fire chief, the laws of the state and other local ordinances.
D. Electrical Interference. Provisions must be made for necessary shielding or other preventive measures against interferences occasioned by mechanical, electrical, electronic and nuclear equipment, uses or processes with electrical apparatus in nearby buildings or land uses.
E. Odors, Gases. The emission of obnoxious odors of any kind shall not be permitted nor the emission of any toxic or corrosive fumes or gases. Dust created by a use shall not be exhausted or wasted directly into the atmosphere.
F. Particulate Matter.
1. The emission of smoke or particulate matter of a density equal to or greater than number three on the Ringlemann Chart as currently established and used by the U.S. Bureau of Mines, is prohibited at all times.
2. Dust and other types of air pollution borne by the wind from such sources as storage areas and roads, shall be minimized by landscaping, paving, oiling or other acceptable means. Emission of particulate matter in excess of 0.2 grain per cubic foot of conveying gas or air measured at any property line, is prohibited.
3. Smoke Emission Rates. The rate of emission of particulate matter from all sources on any property shall not exceed a net weight of one pound per acre of property during any one hour.
G. Waste Disposal. Liquid and solid waste, storage of animal or vegetable waste which attract insects or rodents or otherwise create a health hazard shall be prohibited. No waste products shall be exposed to view from eye level from any property line.
H. Open Storage.
1. All storage shall be located more than 20 feet from the street right-of-way line and shall be enclosed with a heavy wire fence, hedge, board fence, or similar screening device at least six feet high, measured from the adjacent street level.
2. In case of the open storage of lumber, coal or other combustible material, a roadway shall be provided, graded, surfaced and maintained from the street to the rear of the storage area to permit free access of fire trucks at any time.
I. Vibration. Vibration shall not exceed three thousandths of one inch displacement applied to the frequency range of zero to 5,000 cycles per second, as measured at any point on the boundary of the property from which the vibration is produced.
17.60.020 Proof of compliance.
If the city has a reasonable doubt that a business or use is, or can be, conducted within the limits of the above performance standards, it may require that the user or proposed user retain, at his expense, an independent, qualified, testing laboratory to make an analysis of the use to determine its compliance with the standards and to make the results of such analysis available to the city. In the event the analysis discloses existing or impending non-compliances, the city shall require the user or proposed user to either institute remedial measures to bring the use into compliance or to cease operation.
17.60.030 Applicability.
The standards of this chapter apply to all uses. However, they do not apply to unusual and isolated incidents, as determined by the community development director.
