The '.['own of Nantucket is requesting a. variance pursuant to Nantucket Zoning Bylaw Section
1.39-32 (variances} from the height re~iuirements in Section 139-17 (height restrictions} for a
commercial ~%ind Energy Conversion System (~VECS} per section ~ 139-~ 1; Section I3(4). The
Height ofthe proposed ~VECS tower is 7lmeters (23?.9"}, with an overall height from base to
top of rotor estimated to be 99rn (32~.~'}.
The 'T'own of Nantucket is also recluestrng Special hermit relief pursuant to Nantucket Zoning
Bylaw Section t39-30 (spacial permits} to allow for acoustic levels greater than 45 c1B for
said commercial ~~Vind Energy Conversion System (WECS}. `Cho lna~imul~z noise level at the
closest abutting property line (Land Bank} is projected to be SGcll:3, occurring when the, turbine is
operating at l ? meters/second.

ADDENDUM TO ACOUSTIC ANAYLSIS
MADAKET WIND TUBRINE PROJECT
NANTUCKET, MA
October 6, 2011
~._ ~,
The Town of Nantucket (the Client) is proposing to construct a wind turbine on the Nantucket
Landfill property located at 188 Madaket Road in Nantucket, Massachusetts. The proposed
location of the turbine is shown in Figure 1. The turbine is currently proposed to be a
PowerWind PW56 machine, with a power output of 900 kW, a hub height of 71 meters (233
feet), and a 56 meter (184 foot) rotor diameter (i.e. 28 meter blade lengths) with an overall height
of 99 meters (325 feet).
On behalf of the client, Atlantic Design Engineers, LLC has completed an addendum to the
original acoustic analysis prepared for the Madaket Wind Turbine Project, dated February 25,
2011 in order to assess noise effects from the initial two turbine project at various property lines
near abutting residential properties. This addendum has been completed in order to assess a
single turbine project with a location change for the remaining turbine (see Figure 1 for the
revised location). The new study results were evaluated for compliance with The Commonwealth
of Massachusetts Department of Environmental Protection (MA DEP) Noise Control Regulation
310 CMR 7.10, and the Code of the Town of Nantucket, Chapter 101, which addresses general noise
regulations.
Atlantic had previously conducted on-site ambient noise measurements to establish the current
sound pressure levels (in decibels), at four (4) locations on the project property. The information
gathered from these measurements was used in concert with data provided from the wind turbine
manufacturer, wind speed data obtained from an on-site location, and the software program
WindPRO Version 2.7.473 to determine the projected sound levels that will be produced at the
designated locations (see Figure 2) once the turbine is in operation. The data collected at each
location was examined in order to determine a correlation between wind speeds and noise levels,
as typically ambient noise levels increase when wind speed increases. For each location, this
correlation was used by WindPRO to determine the projected noise levels at different wind
speeds. If no correlation could be established due to a lack of varying wind speeds during
measurement periods, then a conservative approach was used that assumes there is no increase in
noise levels as wind speeds increase.
The projected sound values were reviewed for compliance with both the state and town bylaws
and regulations. The results of the calculations are summarized in Tables 1 & 2 (below), which
show the maximum projected sound levels at the chosen locations.

The proposed Madaket Wind Turbine Project complies with noise requirements set forth
in the Code of the Town of Nantucket bylaw on noise by limiting proposed noise levels
to less than 45 dBA at the nearest residences. The noise levels (turbine generated) at
nearby residences are calculated to be a maximum of 41 dBA (Shown in Figure 4). This
is below the 45 dBA sound threshold established by the Town of Nantucket noise bylaw.
• The proposed Madaket Wind Turbine Project complies with the Massachusetts
Department of Environmental Protection Noise Policy by not increasing noise levels at
nearby residential properties by more than 10 decibels. The turbine is expected to
increase the ambient L90 sound level by a range of 0 dBA to 7 dBA at nearby residential
properties (shown in Figure 5), below the DEP allowable. In addition, the PowerWind
PW56 wind turbine is not anticipated to produce any audible "pure tones", as sound
emissions from modern wind turbines are mostly comprised of broadband tones.
The proposed Madaket Wind Turbine Project is projected to have turbine generated noise
levels in excess of 45 dBA at the Town Landfill's property line south of the proposed
turbine. The noise levels (turbine generated) at the nearest property line are calculated to
have a maximum level of 56 dBA. This level is above the 45 dBA nighttime sound
threshold established by the Town of Nantucket noise bylaw. However, the abutting
properties to the project property lines where the 45 dBA is exceeded are all undeveloped
conservation land where present and future development is restricted, and in
conversations with the Nantucket Island Land Bank, owners of the properties in question,
they have indicated they would have no objection to the exceedance of the noise standard
at their property line from the proposed project. See Figure 6 for the projected turbine
generated sound level contours for the proposed project.
