Noise FAQS
What noise mitigation measures are being planned? If the developers are not proposing them, how will BSB protect people from nuisance noise levels? Businesses in the MCTEDD are located in the Ramsay Rural Industrial Zone – RM2. The zoning ordinance for noise for this zone states: “The use shall not create any noise measured on a neighboring residential or nonzoned property not under common ownership with the property on which the noise is generated which exceeds the following levels, measured in decibels on the "A" scale of a standard sound level meter having characteristics defined by the American National Standards Institute, Publication S1.4-1971 (db[A]):1.When the property on which the noise is measured is in a residential or nonzoned district, a maximum db permitted to occur on a ten-percent-of-the-time basis is an L 10 value of 60db(A). E.Earthborne Vibration Standards. No use, operation, or activity, shall cause or create earthborne vibrations in excess of the peak particle velocities prescribed below. 1.Vibration shall be measured at any RM-2 zone boundary line and such measurements shall not exceed a peak particle velocity of 0.2 inches per second. Where vibration is produced as discrete impulses, and such impulses do not exceed a frequency of one hundred per minute, then the peak particle velocity shall not exceed 0.4 inches per second. The instrument used for these measurements shall be a three component measuring system capable of simultaneous measurement of vibration in three mutually perpendicular directions. The maximum particle velocity shall be the vector sum of the three individual components recorded. 2.The maximum vibration is given as particle velocity, which may be measured directly with suitable instrumentation or computed on the basis of displacement and frequency. When computed, the following formula shall be used: a.P.V. = 6.28 F × D b.P.V. = Particle velocity, inches per second c.F = Vibration frequency, cycles per second d.D = Single amplitude displacement of the vibration, inches 3.The following sources of vibration are exempt: a.Transportation vehicles not under the control of the industrial use. b.Temporary construction activity between 7:00 a.m. and 7:00 p.m.
