20D.95.30 Performance Standards.

20D.95.30-010 Vibration.

Recurrently generated ground vibrations shall not be perceptible by a person of ordinary sensitivity, without instruments, at any point of any boundary line of the property on which a use or structure is located. Vibrations from temporary construction activities and vehicles that leave the property (such as trucks, trains, airplanes and helicopters) are excluded. (Ord. 2006)

20D.95.30-020 Glare and Heat.

Any operation producing intense glare or heat shall be conducted within an enclosed building or with other effective screening in such a manner as to make such glare or heat completely imperceptible from any point along the property line. (Ord. 2006)

20D.95.30-030 Light.

Exterior lighting, except for overhead street lighting and warning, emergency, or traffic signals, shall be installed in such a manner that the light source will be sufficiently obscured to prevent glare on public streets and walkways or into any residential zone. The installation or erection of any lighting that may be confused with warning signals, emergency signals, or traffic signals shall be prohibited. (Ord. 2006)

20D.95.30-040 Smoke Emissions.

(1)    No air contaminant that is of such a shade or density as to obscure an observer’s vision to a degree in excess of 20 percent opacity shall be emitted into the atmosphere from any source.

(2)    Exceptions.

(a)    No air contaminant shall be emitted into the atmosphere from any pilot plant or experimental operation for a period or periods aggregating more than three minutes in any 60 consecutive minutes which is of such a shade or density as to obscure an observer’s vision to a degree in excess of 40 percent opacity. This emission standard for pilot plants and experimental operations shall be in effect for a period not to exceed 180 operating days, cumulative total, from the date such operations commence; thereafter, the 20 percent opacity limitations provided in subsection (1) of this section shall apply to emissions from pilot plants and experimental operations.

(b)    Emissions from fireplaces used for noncommercial or recreational purposes shall be exempt from subsection (1) of this section.

(c)    Subsection (1) of this section shall not apply to emissions during the buildup of a new fire, cleaning of fires, soot blowing, start-up, any process modification or adjustment or occasional cleaning of control equipment, the shade or appearance of which is not darker than an equivalent opacity so as to obscure an observer’s view to a degree not greater than 40 percent for a period or periods aggregating no more than three minutes in any one hour.

(d)    Subsection (1) of this section shall not apply to fugitive dust. (Ord. 2006)

20D.95.30-050 Odor Emissions.

(1)    This section shall only apply to uses established after December 24, 1998, or buildings constructed after December 24, 1998.

(2)    Recurrently generated offensive odors shall not be perceptible by a person of ordinary sensitivity, without instruments, at any point of any boundary line of the lot or lots on which the use or structure is located. Odors from temporary construction activities and vehicles that leave the lot (such as trucks, trains, airplanes and helicopters) are excluded. (Ord. 2006)

20D.95.30-060 Radioactivity.

The emission of radioactive material shall comply with the latest requirements of the State of Washington and U.S. Government pertaining to radiation control and radioactive materials. (Ord. 2006)

20D.95.30-070 Electromagnetic Interference.

Electric fields and magnetic fields shall not be created that adversely affect the public health, safety, and welfare including, but not limited to, interference with the normal operation of equipment or instruments or normal radio, telephone, or television reception from off the premises where the activity is conducted. This section does not apply to telecommunication facilities which are regulated by the Federal Communications Commission under the Federal Telecommunication Act of 1996 or its successor. (Ord. 2006)

20D.95.30-080 Loading Operations.

(1)    This section shall only apply to uses established after December 24, 1998, or buildings constructed after December 24, 1998.

(2)    Truck or railroad loading or unloading operations located within 200 feet of a residential zone shall not be conducted between the hours of 10:00 p.m. and 6:00 a.m. unless conducted entirely within an enclosed structure. (Ord. 2006)

20D.95.30-090 Hazardous Materials.

Uses that use and/or store hazardous materials (including hazardous wastes) on site shall comply with all fire and building codes applicable to structures containing hazardous materials and with all State and federal requirements. Adequate precautions shall be taken to protect against negative off-site impacts from a hazardous materials release by the using best available technology. (Ord. 2006)
