The Industrial District is established as a district in which
the principal use of land is for industries which do not emit noise,
vibration, smoke, dust, odors, heat, glare, and other influences sufficient
to constitute an adverse influence and detract from adjacent residential
or commercial zoning districts.
In reviewing site plans for proposed development in the Industrial
District, the Planning Commission shall consider the degree to which
a proposed use may result in any effects that may create any dangerous,
injurious, noxious or otherwise objectionable element or condition
so as to adversely affect the surrounding area or adjoining premises;
provided, however, any use permitted in this chapter may be undertaken
and maintained if the site plan includes measures acceptable to the
Planning Commission to limit dangerous or objectionable effects on
adjoining properties, as established by the following performance
requirements:
A. Sound. The emission of noise measurable in decibels (dB) on a persistent
or frequently recurrent basis from the premises shall not exceed the
sound levels outlined in the table below, when measured at any property
line. These regulations do not apply to construction activities, maintenance
activities, noises of safety signals, warning devices, emergency pressure
relief valves, or special community events approved by Township Board.

B. Vibration. All machinery shall be so mounted and operated as to prevent
transmission of ground vibration exceeding a displacement of 0.003
inch measured at any lot line of its source. Vibration from sound
or noise at any lot line shall not be so intrusive as to interfere
with normal daily activities in adjoining land uses.
C. Odor. The emission of noxious, odorous matter in such quantities
as to be readily detectable at a point along any lot lines, when diluted
in the ratio of one volume of odorous air to four or more volumes
of clean air, so as to produce a public nuisance or hazard beyond
lot lines.
D. Toxic gases. The escape or emission of any gas, which is injurious
or destructive or explosive, shall be unlawful and shall be summarily
abated, as directed.
E. Glare and heat. Any operation producing intense glare or heat shall
be performed within an enclosure so as to completely obscure and shield
such operation from direct view from any point along the lot line,
except during the period of construction of the facilities to be used
and occupied.
F. Light. All lighting shall be arranged to reflect light away from adjacent parcels and must follow the standards outlined in §
380-12.12.
G. Electromagnetic radiation. The rules and regulations of the Federal
Communications Commission, as amended, with respect to the propagation
and dissemination of electromagnetic radiation must be followed and
are hereby made a part of this chapter.
H. Drifted and blown material. The drifting or airborne transmission
beyond the lot line of soot, particles, or debris from any stockpile
shall be unlawful and shall be summarily abated, as directed.
I. Smoke, dust, dirt, and fly ash. It shall be unlawful to discharge
into the atmosphere from any single source of emission whatsoever
any air contaminator, for a period or periods aggregating more than
three minutes in any 60 minutes, which is more than 40% opaque.
