This chapter permits specific uses in specific
districts, and these performance standards are designed to limit,
restrict, and prohibit the effects of those uses outside their premises
or district. All structures, lands, air, and waters shall hereafter,
in addition to their use, site, and sanitary regulations, comply with
the following performance standards.
No person or activity shall emit any fly ash,
dust, fumes, vapors, mists, or gases in such quantities so as to substantially
contribute to exceeding established state or federal air pollution
standards.
All activities involving the manufacturing,
utilization, processing, or storage of flammable and explosive materials
shall be provided with adequate safety devices against the hazard
of fire and explosion and with adequate fire-fighting and fire-suppression
equipment and devices that are standard in the industry. All materials
that range from active to intense burning shall be manufactured, utilized,
processed and stored only in completely enclosed buildings which have
incombustible exterior walls and an automatic fire extinguishing system.
The above-ground storage capacity of materials that produce flammable
or explosive vapors shall not exceed the following:
|
Closed Cup Flash Point
|
Gallons
|
---|
|
Over 187º F.
|
400,000
|
|
105º F. to 187º F.
|

|
|
Below 105º F.
|
100,000

No activity shall emit glare or heat that is
visible or measurable outside its premises except activities which
may emit direct or sky-reflected glare which shall not be visible
outside their district. All operations producing intense glare or
heat shall be conducted within a completely enclosed building. Exposed
sources of light shall be shielded so as not to be visible outside
their premises.

A. Sound limitation.
(1) The maximum allowable hourly average sound level emitted from any stationary sound source shall not exceed the limits set forth in
Table 1 when measured at the nearest lot line of premises from which sound complaints are received.

(2) "Average sound level" means a sound level typical of the sound levels
observed at a certain place during a given period of time averaged
by the general rule of combination for sound levels, such general
rule being set forth in ANSI specifications for sound level meters.
"Average sound level" is also called "equivalent continuous sound
level (Leq)."
(a)
Correction for ambient conditions.
[1]
Where the ambient sound level influences a measurement at a
property boundary, such sound will be accounted for by applying the
following correction factors:
|
---|
If the ambient sound level is less than the sound source by:
|
Add the following to the sound limit:
|
---|
0 to 1 dBA
|
3 dBA
|
2 to 3 dBA
|
2 dBA
|
4 to 9 dBA
|
1 dBA
|
[2]
If the ambient sound level is greater than the sound limit,
the sound source shall not be allowed to exceed the ambient level.
[3]
"Ambient sound level" means the sound pressure level of all-encompassing
sounds associated with a given environment, being a composite of many
sounds. For the purposes of this chapter, such term is the sound pressure
level exceeded 90% of the time, based upon a measurement of not less
than 10 minutes and excluding the alleged offensive sounds.
(3) Exemptions. The provisions of this section shall not apply to:
(a)
Any sounds allowed under other provisions of the City of Burlington Code of Municipal Ordinances. This shall expressly include, but not be limited to, sounds allowed under §
219-3 and/or this Chapter
315 of the Code of Municipal Ordinances (such as, but not limited to, a variance and/or a conditional use permit).
(b)
Any sounds generated in a manufacturing, business, and/or quarrying/extractive
district that do not comply with the sound levels of this chapter,
but which are nonetheless still approved by the City of Burlington
Common Council, because the noncompliant sound is, as determined by
the Common Council, in its sole and absolute discretion, (i) necessary
for the conducting of the lawful activities otherwise allowed on the
site in question, but (ii) such noncompliant sound is not reasonably
capable of being made compliant for technical and/or economic reasons,
and (iii) such noncompliant sound is not contrary to the public safety,
health, and welfare of the community. The approval of the Common Council
of the noncompliant sound may be subject to such conditions and/or
limitations as the Common Council may determine.
B. Method of measurement.
(1) Equipment. Sound measurement shall be made with a sound level meter
manufactured according to the specifications of the American National
Standards Institute, USA Standard Specifications for General Purpose
Sound Level Meters and Preferred Center Frequencies for Acoustical
Measurements, or any subsequent nationally adopted standards superseding
the above standards.
(2) Location and interpretation. Sound measurement shall be made at the
nearest lot line of premises from which sound complaints are received
and shall be made at a height of at least three feet above the ground
and at least three feet away from walls, barriers, obstructions or
sound reflective surfaces. Where the nature of the sound level permits,
the slow response setting shall be used to obtain the sound level
on the sound level meter.
C. Application for exemption stays prosecution. If a person or entity
is given a citation in the City of Burlington Municipal Court system
for a violation of this chapter, and if that person/entity so cited
applies for an exemption from the said sound violation under above
Subsection A(2)(b) of this ordinance within 15 calendar days after
the date of the issued citation, the action in the Municipal Court
shall be stayed until the Common Council makes its determination under
above Subsection A(2)(b). If the Common Council approves the application
filed under Subsection A(2)(b) for the allowance of the noncompliant
sound (whether with or without conditions or limitations), the legal
proceeding in the Municipal Court shall then be dismissed.
[Amended 7-5-1994 by Ord. No. 1477(6)]
No activity shall emit any odorous matter of
such nature or quantity as to be offensive, obnoxious, or unhealthful
outside its premises. The guide for determining odor measurement and
control shall be § NR 429.03, Wis. Admin. Code, and amendments
thereto.
No activity shall emit radioactivity or electrical
disturbances outside its premises that are dangerous or adversely
affect the use of neighboring premises.
No activity in any district shall emit vibrations
which are discernible without instruments outside its premises. No
activity shall emit vibrations which exceed the following displacement
measured with a three-component measuring system:
