15.460.005 Purpose

The purpose of this chapter is to establish general limits on noise, glare, and other forms of pollution, which are hazardous and/or disruptive to the citizens of the City of SeaTac. (Ord. 15-1018 § 1)

15.460.010 Authority and Application

The following performance standards specifically govern industrial, manufacturing, processing, assembly and similar type uses typically found within industrial zones. These standards may also apply to other uses and activities in other zones, which are not otherwise governed by other regulations of this code. (Ord. 15-1018 § 1)

15.460.020 Noise

A.    The noise emanating from the premises of industrial activities shall be muffled so as not to contribute to existing background noise, or become objectionable to adjacent residential property owners due to intermittent beat, frequency or shrillness, and shall not exceed those standards as determined by the Washington Administrative Code as amended.

B.    Unusual noises, aside from the normal associated noises of the SeaTac Airport related to aircraft operations, emanating from the premises of residential or commercial use shall be muffled so as not to contribute to existing background noise, or become objectionable due to intermittent beat, frequency or shrillness, and shall not exceed those standards as determined by the Washington Administrative Code as amended.

C.    Due to the proximity of the airport facilities, residential construction shall have sound attenuated or limited as consistent with adopted Port of Seattle/FAA noise remedy programs within significant LDN contours. (Ord. 15-1018 § 1)

15.460.030 Glare

Exterior lighting shall not be used in such a manner that it produces glare on public streets and neighboring property. This restriction also applies to any other nonresidential zone or use adjacent to single-family zones. Arc welding, acetylene torch cutting or similar processes shall be performed so as to be shielded from any adjacent properties or public roads. The glare of the torch shall not extend beyond the property line of the use (residential, commercial or industrial) creating the glare. (Ord. 15-1018 § 1)

15.460.040 Storage and Handling of Flammable Materials

In terms of fire and safety hazards, the storage and handling of flammable liquids, combustible liquids, liquefied petroleum gases and explosives shall comply with rules and regulations falling under the jurisdiction of the City of SeaTac, State of Washington and Federal agencies.

Any of the above-referenced tanks shall be located no closer to the property line than the greatest dimension (diameter, length or height) of the tank. (Ord. 15-1018 § 1)

15.460.050 Electrical Interference

Provisions must be made for necessary shielding or other preventive measures against the interference occasioned by mechanical, electrical or nuclear equipment uses or processes with electrical apparatus in nearby buildings or land uses. (Ord. 15-1018 § 1)

15.460.060 Odorous Gases and Matter

The emission of odorous gases or matter in such quantities as to be readily detectable without special instruments is prohibited at any point beyond the property line of the use creating the odor. (Ord. 15-1018 § 1)

15.460.070 Smoke and Particulate Matter Emissions

No emissions shall exceed the allowances set forth by the Environmental Protection Agency, the Washington State Department of Ecology and/or the Puget Sound Air Pollution Control Agency. (Ord. 15-1018 § 1)

15.460.080 Dust, Dirt, Flyaway Ash, or Airborne Solids

No observable fugitive dust, dirt, flyaway ash or other airborne solids shall be emitted from completed development, without adequate mitigation measures to prevent such situations. (Ord. 15-1018 § 1)

15.460.090 Commercial Storage

Storage of animal or vegetable wastes which attract insects or rodents creates a health hazard, and shall be prohibited. No waste products shall be exposed to view, from eye level, beyond the property line of the use storing the waste. (Ord. 15-1018 § 1)

15.460.100 Toxic Gases and Matter

No emissions of toxic gases or matter shall be permitted. (Ord. 15-1018 § 1)
