It is the intent to use performance standards for the regulation
of all uses to facilitate a more objective and equitable basis for
control and to ensure the community is adequately protected from potentially
hazardous and nuisance-like effects. The performance standards shall
apply to all zoning districts. Determinations necessary for the administration
and enforcement of these standards range from those which can be made
by a reasonable person using normal senses and no mechanical equipment
to those requiring substantial technical competence and complex equipment.
It is the intent of this chapter that the methods to be used in determining
compliance shall be the responsibility of the Community and Economic
Development Director or designee. Whenever the Community and Economic
Development Director or designee has reason to believe the standards
of this chapter have been violated, they shall initiate enforcement
as authorized by this chapter.

(3)
All noise shall be so muffled or otherwise controlled as not
to become objectionable due to intermittence, duration, beat frequency,
impulse character, periodic character, or shrillness.
B.
Vibration.
(1)
No operation or activity shall transmit any physical vibration
perception threshold of an individual at or beyond the property line
of the source. "Vibration perception threshold" means the minimum
ground or structure-borne vibrational motion necessary to cause a
normal person to be aware of the vibration by such direct means as,
but not limited to, sensation by touch or visual observation of moving
objects.
(2)
Vibrations not directly under the control of the property user
and vibrations from temporary construction or maintenance activities
shall be exempt from the above standard.
C.
External lighting. No operation or activity shall produce any intense glare or lighting. Reference: Part 320-600, Article III, Lighting.
D.
Odor. No operation or activity shall emit any substance or combination
of substances in such quantities that create an objectionable odor
as defined in Chapter NR 429.03, Wis. Adm. Code.
E.
Particulate emissions. No operation or activity shall emit into the
ambient air from any direct or portable source any matter that will
affect visibility in excess of the limitations established in Chapter
NR 415, Wis. Adm. Code.
F.
Visible emissions. No operation of activity shall emit into the ambient
air from any direct or portable source any matter that will affect
visibility in excess of the limitations established in Chapter NR
431, Wis. Adm. Code.
G.
Hazardous pollutants. No operation or activity shall emit any hazardous
substances in such a quantity, concentration or duration as to be
injurious to human health or property, and all emissions of hazardous
substances shall not exceed the limitations established in Ch. NR
445, Wis. Adm. Code.
