18.53.020 Performance standards.

A. The following performance standards shall apply to all uses in this zone:

1. Noise.

a. At no point on the boundary of property having zoning other than I-2 shall the sound pressure level of any individual operation or plant, excluding operation of motor vehicles or other transportation facilities, exceed the decibel levels in the designated octave bands, as follows:

1.    Octave Band

    (Cycles Per Second)

2.    Maximum Sound Pressure Level in Decibels

    (0.002 Dynes Per CM2)








































b. Sound levels shall be measured with a sound level meter and associated octave band filter manufactured according to standards prescribed in the American Standards Association. Measurements shall be made using the flat network of the sound level meter.

c. Impulsive type noises shall be subject to the performance standards prescribed; provided, that such noises shall be capable of being accurately measured with such equipment.

(1) Noises capable of being so measured, for the purpose of this section, shall be those noises which cause rapid fluctuations of the needle of the sound level meter with a variation of no more than plus or minus two decibels.

(2) Noises incapable of being so measured, such as those of an irregular or intermittent nature, shall be controlled so as not to become a nuisance to adjacent uses.

2. Smoke.

a. No emission of smoke from any source shall be permitted to exceed a greater density than that density described as No. 1 on the Ringlemann Chart;

b. However, smoke may be emitted, which is equal to but not darker than No. 2 on the Ringlemann Chart, for not more than four minutes in any 30-minute period;

c. For the purpose of grading the density of smoke, the Ringlemann Chart, as published by the U.S. Bureau of Mines, shall be the standard.

3. Glare or Heat. Any activity producing intense glare or heat shall be performed in such manner as not to create a nuisance or hazard along lot lines.

4. Odors. No emission of odorous gases or other odorous matter shall be permitted in such quantities as to be offensive in such a manner as to create a nuisance or hazard beyond the property line.

5. Vibration. No vibration shall be permitted which is discernible beyond the lot line to the human sense of feeling for:

a. Three minutes’ or more duration in any one hour of the day between the hours of 7:00 a.m. and 7:00 p.m.; or

b. Thirty seconds’ or more duration in any one hour during the hours 7:00 p.m. to 7:00 a.m.

6. Fly Ash, Dust, Fumes, Vapors, Gases and Other Forms of Air Pollution. No emission shall be permitted which can cause any damage to health, to animals or vegetation, or other forms of property, or which can cause any excessive soiling;

7. Liquids and Solid Waste. No wastes shall be discharged in the streets, drainageways or any property which is dangerous to the public health and safety, and no waste shall be discharged in the public sewage system which endangers the normal operation of the public sewage system.
