Definitions. As used in this subsection, the following terms shall have the meanings indicated:
ADVERSE SOUND CHARACTER
Sound that causes building rattle, is impulsive, tonal, or has low-frequency bass rumble.
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.
PASQUILL STABILITY CLASS
Reference, wikipedia.org "Outline of air pollution dispersion."
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.
SCADA (SUPERVISORY CONTROL AND DATA ACQUISITION)
A computer system that monitors and controls WECS units.
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.
WIND ENERGY CONVERSION SYSTEM (WECS) TESTING FACILITY
A structure and equipment such as a meteorological tower for the collection of wind data and other meteorological data and transmission to a collection source, shall not be deemed to be a communication tower.
