A.

The performance standards that are included within this chapter are to be considered maximum standards and shall apply to all home occupations, commercial, and industrial development in all zones and in certain zoning districts as noted.

B.

Performance of these uses will be of such a nature that they do not inflict upon the surrounding residential, commercial, and industrial areas and uses smoke, dirt, glare, odors, vibration, noise, excessive hazards or air and water pollution detrimental to the public health, safety, and welfare and causing injury to human, animal, or plant life and property. After appropriate measurements have been taken and found that the results exceed these maximum standards, the violation shall be considered a nuisance, declared in violation of the standards, and ordered abated by the city.

(Ord. 490 § 12.01(part), 1979)

A.

Sound shall be muffled so as not to become objectionable due to intermittence, beat frequency, or shrillness. The measurement of sound shall be as noted in the following table and shall be measured in decibels with a sound level meter and associated octave band filter, manufactured according to standards prescribed by the American Standards Association. Measurements for alleged violations shall be made on at least three nonconsecutive days. Maximum permissible sound pressure levels shall comply with the following:

Table 1

Pre-1960 Octave Band Method

B.

Octave band analyzers manufactured after 1960 and calibrated in the Preferred Frequencies (American Standards Association 51.6-1960, Preferred Frequencies for Acoustical Measurements) shall be used according to the following table:

Table 2

C.

Impact noise shall be measured using the fast response of the sound level meter. Measurements are to be made at any point along district boundaries as indicated in Tables 1 and 2. Impact noises are intermittent sounds such as from a punch press or drop forge hammer.

(Ord. 490 § 12.02(1), 1979)

(Ord. 490 § 12.03 (part), 1979)

Smoke shall not be emitted from any source in a greater density of grey than that described as No. 1 on the Ringlemann Chart, except that visible grey smoke of a shade not darker than that described as No. 2 on the Ringlemann Chart may be emitted for not more than four minutes in any thirty minutes. The provisions applicable to visible grey smoke shall also apply to visible smoke of different color, but with an equivalent apparent opacity.

(Ord. 490 § 12.03(1), 1979)

The emission of dust, particulates, and any airborne solids shall be governed by Washington State and Southwest Air Pollution Control Authority standards and regulations. Particulate matter emission from materials or products subject to becoming windborne shall be kept to a minimum by paving, oiling, wetting, covering or other means, such as to render the surface wind resistant. Such sources include vacant lots, unpaved roads, yards and storage piles of bulk material such as coal, sand, cinders, slag, sulfur, etc.

(Ord. 490 § 12.03(2), 1979)

Odors from gases or other odorous matter shall not be in such quantities as to be detectable beyond the exterior property lines of the lot or site.

(Ord. 490 § 12.03(3), 1979)

No visible or invisible noxious gases and fumes shall be discharged into the atmosphere from any continuous or intermittent operation except as is common to the normal operation of a heating plant or motor vehicle, railroad, and aircraft engines.

(Ord. 490 § 12.03(4), 1979)

No use shall discharge into the air, storm drains, sewer systems, or across lot boundaries any toxic or noxious gases or matters in any concentrations as to be detrimental to or endanger the public health, safety or welfare, or cause injury or damage to animals, vegetation, property, or adjacent and nearby businesses. The disposal of industrial wastes shall be governed by the regulations and standards of applicable state and federal agencies.

(Ord. 490 § 12.04, 1979)
