The purpose of this section is to protect the public health, safety and general welfare by applying environmental regulations to all industrial uses and utilities, and manufacturing planning districts in the City. These environmental regulations are also intended to protect natural areas from the adverse effects of industrial development. It is intended that the following standards provide statutory authority for the enforcement of regulations relating to noise, vibration, air quality, odors, heat, glare and lighting, storage and stored materials, liquid and solid waste materials, and dangerous substances.

The regulations of this Chapter apply to:

(1)

All industrial uses and utilities, regardless of the Planning District in which they are located, and

(2)

All Manufacturing Planning Districts, regardless of the use category.

All uses and development must comply with the Oregon State Department of Environmental Quality standards relating to noise and the City of Tualatin noise ordinance in, TMC 6-14.

(1)

Restrictions. All uses and development must not cause or permit ground vibration into the property of another person that exceeds the limits set forth below in this section.

(a)

Ground vibration as measured at the boundary of a residential planning district and an industrial planning district must not exceed 0.01 inches per second (0.00025 meters per second) RMS velocity.

(b)

Ground vibration as measured at a common property boundary of any two properties within any industrial planning district must not exceed 0.1 inches per second (0.0025 meters per second) RMS velocity.

(2)

Method of Measurement. Vibration measurement procedures must conform to the methods described in this section and to procedures approved by the Oregon Department of Environmental Quality.

(a)

Instrumentation must be capable of measuring RMS value of the vibration velocity over the frequency range of ten to 1,000 hertz.

(b)

Measurement values must be recorded for a sufficient period of observation to provide a representative sample.

(c)

Attachment of the vibration transducer to the ground must be by magnetic or screw attachment to a steel bar of a minimum of nine inches (22.9 cm.) in length, driven flush with the ground surface.

(3)

Exemptions.The requirements of TDC 63.052(1) do not apply to:

(a)

Vibration resulting from the operation of any equipment or facility of a surface carrier engaged in interstate commerce by railroad;

(b)

Vibration resulting from the operation of any road vehicle;

(c)

Vibration resulting from construction activities and use of construction equipment; and

(d)

Vibration resulting from roadway maintenance and repair equipment.

(1)

Restrictions. All uses and development must comply with the most recent air quality standards adopted by the Oregon Department of Environmental Quality. Plans of construction and operations must comply with the recommendations and regulations of the State Department of Environmental Quality.

(2)

Method of Measurement. All measurements of air pollution must be by the procedures and with equipment approved by the State Department of Environmental Quality or equivalent and acceptable methods or measurement approved by the City. Upon request of the City, persons responsible for a suspected source of air pollution must provide quantitative and qualitative information regarding the discharge that will adequately and accurately describe operation conditions.

All uses and development must not emit odors in such quantities as to create a nuisance condition at any point beyond the subject property line of the emitting use.

(1)

All uses and development must conduct all operations producing heat or glare entirely within an enclosed building.

(2)

All uses and development may utilize exterior lighting, but the exterior lighting must be screened, baffled or directed away from residential planning districts.

(1)

All uses and development must store all materials, including wastes, in a manner that will not attract or aid the propagation of insects or rodents, or in any other way create a health or safety hazard.

(2)

All uses and development that utilize open storage that would otherwise be visible at the property line must conceal it from view at the abutting property line by a sight obscuring fence not less than six feet high and not accessible to the general public to protect public safety.

All uses and development are prohibited from disposing waste onto the site or into adjacent drainage ditches, creeks or other natural waterways in violation of State of Oregon DEQ standards, Clean Water Services Standards, City Standards, or in a manner that causes harm to wildlife.

All uses and development are prohibited from the storage, transfer, or processing of hazardous, toxic, or radioactive waste.
