Thank you very much for your consideration of this statement of some of the omissions, inconsistencies, and inaccuracies in the Binks SUP application. Respectfully Submitted, May 27, 2014 John G. Petranka 2531 Falls Drive Chapel Hill, NC 27514 919-383-7855 919-667-6112 (cell) john.petranka(a�qmail.com Appendix I Calculation of Noise Produced by a Group of Three Inverters. Assuming that each 1500 kW inverter group consists of three Advanced Energy Solaron 500 inverters, the noise level generated by adding all three can be calculated as shown below (source: The Engineering Toolbox: Adding Decibels. http://www.enqineerinqtoolbox.com/addinq-decibel-d 63.html ) The resulting sound pressure level when adding equal sound pressures is calculated by the formula: Lpt = Lps + 20 log (n), where: Lpt = total sound pressure level (dB) Lps = sound pressure level from each single source (= 68 dB at a distance of one meter for each inverter in the group of three) n = number of sources (= three 500 kW units per 1500 kW station) Substituting: Lpt= 68 dB + 20 x log (3) Lpt= 68 dB + 20 x (.47712) = 68dB + 9.54 dB So, Lpt = 77.54 dB at 1 meter Appendix II: Sound Level Measurements Background Sound Averaging ca. 32 dB. Periodic increases are attributable to songs of nearby birds. Location of Sound Measurement. Corner of Cascade Dr. (to Sally's right) and Falls Dr. (intersecting on the left). Proposed 20 acre development is property along Cascade Dr. behind zoning sign. John Petranka— My name is John Petranka, and I have been duly sworn. My wife and I have lived in the Falls of New Hope Neighborhood for almost 23 years. We live at 2531 Falls Drive, which is right on the corner of Falls and Cascade and directly across the street from the proposed development. We chose to live in our neighborhood intentionally.
