Definitions. As used in this subsection, the following terms shall
have the meanings indicated:
AMBIENT
The sound pressure level exceeded 90% of the time over a
ninety-six-hour measurement period with daytime/nighttime division.
ANSI
The American National Standards Institute.
AUDIBLE
The varying degrees of sound perception as reported by affidavit,
including, but not limited to, just perceptible, audible, clearly
audible, and objectionable.
dBA
The A-weighted sound level.
dBC
The C-weighted sound level.
DECIBEL (dB)
The practical unit of measurement for sound pressure level;
the number of decibels of a measured sound is equal to 20 times the
logarithm to the base 10 of the ratio of the sound pressure of the
measured sound to the sound pressure of a standard sound (20 micropascals);
abbreviated "dB."
EMERGENCY WORK
Any work or action necessary to deliver essential services
in an emergency situation, including, but not limited to, repairing
water, gas, electricity, telephone and sewer facilities and public
transportation, removing fallen trees on public rights-of-way, and
abating life-threatening conditions.
EQUIVALENT SOUND LEVEL (or Leq)
The sound level measured in decibels with an integrating
sound level meter and averaged on an energy basis over a specific
duration.
EXCESSIVE NOISE
Sound that is determined by ordinance to be too loud or unnecessary
or creates a noise disturbance.
GIS
Geographic information system and is comparable to GPS (global
positioning system) coordinates.
L10
The noise level exceeded for 10% of the time of the measurement
duration. This is often used to give an indication of the upper limit
of fluctuating noise, such as that from road traffic.
L90
The noise level exceeded for 90% of the time of the measurement
duration and is commonly used to determine ambient or background noise
level.
NOISE
A sound, especially one that is loud or unpleasant or that
causes disturbance. Any airborne sounds of such level and duration
as to be or tend to be injurious to human health or welfare (well-being)
or that would unreasonably interfere with activities or the enjoyment
of life or property.
NONPARTICIPATING LANDOWNER
A landowner who has not signed a contract or any legal document
with the WECS applicant and has not given up rights to their owned
land to the WECS applicant.
PARTICIPATING LANDOWNER
A landowner who has leased land to the WECS applicant, received
financial remuneration from the WECS applicant, recorded with the
Van Buren County Register of Deeds said agreement, and has a contract
with the WECS applicant. A participating landowner may also be called
a "WECS contract leaseholder." A participating landowner may or may
not have turbines or infrastructure located on their property.
QUIET RURAL OR RESIDENTIAL PROPERTY
Any property where there is an inherent expectation of quiet,
including, but not limited to, all residential, business, or agricultural-zoned
properties, single-family homes, and retirement homes.
SOUND LEVEL METER
An instrument for the measurement of sound levels that meets
the ANSI requirements of S1.4-1983 (or later revision) for Type 1
or 2 instruments. For frequency analysis, octave and 1/3 octave filters
shall conform to ANSI S1.11-1986 (or later revision).
SURVIVAL WIND SPEED
The maximum wind speed, as designated by the WECS manufacturer,
at which a WECS in unattended operation (not necessarily producing
power) is designed to survive without damage to any structural equipment
or loss of the ability to function normally.
TIP HEIGHT
The height of the turbine with a blade at the highest vertical
point.
WECS APPLICANT
The person, firm, corporation, company, limited liability
corporation or other entity, as well as the applicant's successors,
assigns and/or transferees, which applies for Township approval (permit)
to construct a WECS and WECS testing facility. An applicant must have
the legal authority to represent and bind the participating landowner,
or lessee, who will construct, own, and operate the WECS or testing
facility. The duties and obligations regarding a zoning approval for
any approved WECS or testing facility shall be with the WECS or testing
facility owner, and jointly and severally with the owner, operator,
and lessee of the WECS or testing facility if different than the WECS
owner.
