(1) Air Quality. No visible or invisible noxious, toxic, or corrosive fumes or gases or particulate emissions, or suspended particles or fugitive dust emissions, shall be discharged into the atmosphere except such as are common to the normal operation of a heating plant or gasoline or diesel engines in cars, trucks, or railroad engines. Where such emissions could be produced as a result of accident or equipment malfunction, adequate safeguards standard for safe operation in the industry involved shall be taken. This shall not be construed to prohibit spraying of pesticides or herbicides on public or private property. Equipment or vents that generate air emissions shall be located on the opposite side of the building from adjoining residentially designated properties.

(2) Vibrations. Every use shall be so operated that any air or ground vibration generated from equipment other than vehicles is not perceptible without instruments at any point on or beyond the property boundaries.

(3) Waste Storage and Disposal. The storage or disposal of industrial waste shall be subject to the regulations of the State Health Department and shall comply with the requirements of the Washington Pollution Control Commission.

(4) Electrical Interference. Provisions must be made for necessary shielding or other preventive measures against interference caused by mechanical, electrical, or nuclear equipment uses or processes with electrical apparatus in nearby buildings or use areas.

(5) Noise. The noise resulting from any activity other than noise produced by vehicles and other transportation facilities and construction and maintenance of buildings and grounds shall not be audible at any point on or beyond the property boundaries. Equipment or vents that generate noise shall be located on the opposite side of the building from any adjoining residentially designated properties.

(6) Fire and Explosive Hazards. The manufacture, use, processing or storage of flammable liquids or materials, liquids or gases which produce flammable or explosive vapors or gases shall be permitted in accordance with the regulations of the uniform building and fire codes, SMC Title 14.

(7) Steam. Any use producing humidity in the form of steam or moist air shall be carried on in such a manner that humidity is not perceptible at or beyond property boundaries.

(8) Heat. Any use producing heat shall be carried on in such a manner that heat is not perceptible at or beyond property boundaries.

(9) Odors. To promote the health, safety and welfare of the community and to maintain compatibility of surrounding land uses, any use producing odors shall be carried on in such a manner that offensive or obnoxious odor shall not be perceptible by a minimum of five people with ordinary sensitivity without instruments, at or beyond the property boundaries. Facilities shall comply with the “no detectable odor emission” standard, which means: systems shall be designed to remove offensive odors and sized to handle worst-case operating conditions when combinations of meteorological conditions, such as inversions and stagnant air, coincide with peak odor releases from treatment processes. This is not intended to prevent a single odor emission released as a direct result of necessary facility maintenance.

(10) Glare. Artificial lighting shall be hooded or shaded so that direct light of high intensity lamps will not result in glare when viewed from surrounding areas. Lighting fixtures that conflict with the readability of traffic control devices, rotate or flash are prohibited.

(11) Ground Contamination. Materials used or produced in any manufacturing process shall be handled in such a manner as to prevent ground or soil pollution that destroys or endangers natural and environmental resources as noted in SMC 17.50.030.

(12) The following uses are prohibited:
