  § 8.07. Performance Standards for Flex and Industrial Uses.  

Latest version.

  • The following standards shall be met unless there are greater standards required by the United States Environmental Protection Agency or the Nebraska Department of Environmental Quality.

    8.07.01

    Physical Appearance. All operations shall be carried on within an enclosed building except that new materials or equipment in operable condition may be displayed or stored in the open, if the applicable zoning district permits. Normal daily wastes of an inorganic nature may be stored in containers not in a building when such containers are not readily visible from a street. The provisions of this paragraph shall not be construed to prohibit the display of merchandise or vehicles for sale or the outdoor storage of vehicles, boats, farm machinery, trailers, mobile homes, or similar equipment when in operable condition. Outdoor storage shall be visually screened from public roadways and residential properties.

    8.07.02

    Fire hazard. No operation shall involve the use of highly flammable gasses, acid, liquids, grinding processes, or other inherent fire hazards. This provision shall not be construed to prohibit the use of normal heating fuels, motor fuels and welding gasses when handled in accordance with other regulations of the City of Bellevue.

    8.07.03

    Noise. No operation shall be carried on which involves noise in excess of the normal traffic noise of the adjacent street at the time of the daily peak hour of traffic volume or in excess of eighty (80) decibels, whichever is greater. Noise shall be measured at the property line and when the level of such noise cannot be determined by observation with the natural senses, a suitable instrument may be used and measurement may include breakdowns into a reasonable number of frequency ranges.

    8.07.04

    Exterior Lighting. Exterior lighting, when used, shall enhance the building design and the adjoining landscape. Building fixtures shall be of a design and size compatible with the building and adjacent areas. Lighting shall be restrained in design and excessive brightness avoided. Lighting shall be designed to a standard that does not impact adjoining properties, especially residential areas and public right-of-ways.

    8.07.05

    Sewage and Liquid Wastes. No operation shall be carried on which involves the discharge of waste into a storm sewer, water course, or the ground; nor should any liquid waste of any radioactive or poisonous nature or chemical waste which are detrimental to normal sewage plant operation or corrosive and damaging to sewer pipes and installations be dumped into wastewater sewerage.

    8.07.06

    Air Contaminants.

    1.

    Air Contaminants and smoke shall be less dark than designated Number One on the Ringleman Chart as published by the United States Bureau of Mines, except that smoke of a density designated as Number One shall be permitted for one four minute period in each one-half hour. Light colored contaminants of such an capacity as to obscure an observer's view to a degree equal to or greater than the aforesaid shall not be permitted.

    2.

    Particulate matter of dust as measured at the point of emission by any generally accepted method shall not be emitted in excess of two tenths (0.2) grains per cubic foot as corrected to a temperature of 500 degrees Fahrenheit, except for a period of four minutes in any one-half hour, at which time it may equal but not exceed six tenths (0.6) grains per cubic foot as corrected to a temperature of 500 degrees Fahrenheit.

    3.

    Due to the fact that the possibilities of air contamination cannot reasonably be comprehensively covered in this section, there shall be applied the general rule that there shall not be discharged from any sources whatsoever such quantities of air contaminants or other material in such quantity as to cause injury, detriment, nuisance, or annoyance to any considerable number of persons or to the public in general; or to endanger the comfort, repose, health, or safety of any such considerable number of persons or to the public in general, or to cause, or have a natural tendency to cause injury or damage to business, vegetation, or property.

    4.

    Odor. The emission of odors that are generally agreed to be obnoxious to any considerable numbers of persons, shall be prohibited. Observations of odor shall be made at the property line of the establishment causing the odor. As a guide to classification of odor it shall be deemed that strong odors of putrefaction and fermentation tend to be obnoxious and that such odors as associated with baking or the roasting of nuts and coffee shall not normally be considered obnoxious within the meaning of this ordinances.

    5.

    Gasses. The gasses sulphur dioxide and hydrogen sulphide shall not exceed five parts per million, carbon monoxide shall not exceed five parts per million. All measurements shall be taken at the zoning lot line.

    6.

    Vibration. All machines including punch presses and stamping machines shall be so mounted as to minimize vibration and in no case shall such vibration exceed a displacement of three thousands (0.003) of an inch measured at the zoning lot line. The use of steam or broad hammers shall not be permitted in this zone.

    7.

    Glare and heat. All glare, such as welding arcs and open furnaces shall be shielded so that they shall not be visible from the zoning lot line. No heat from furnaces or processing equipment shall be sensed at the zoning lot line to the extent of raising the temperature of air or materials more than five degrees Fahrenheit.
