RE: Request for Waiver ol."Site Plan Review
Dear Mr. Scott;
Shoo,shanian Process Fligineering and, Coristructilon ("SPEC ), the building contracto�r, for
Pharm-Eco, Laboratories, has applied, for as bUilding permit to coml a partial second
floor in Unit 2 at 70 Flagship Drive,. Anothler plt!rmill currently exists and consinlivtion is
umder,way fior a first floor pro-ject at that location.
Upon. review of our Plans lbr the partial second floot- by the Building Department,
Pliarm- `co was irifi.xilmed that the gI-ON% ,,,,ec()nd Iloor area was more than 2000 square feet:
and would need as Plamaing Board site than review, taking approximately 45-610 days,
However, we do not believe that the regulations of the Zoning Bylaw Tlxequire such as site
114111 reView,,
We believe that th.e issue here is simply the interpretation of"gro."; 11olor arca5, as that
term is used in the Dylaw regulations. T-TI.ider Section 8.3.2l.a.ii, the actual "gross fluor
area" of the ccond level is, 1993 s,q. ft., as sliown on SPEC.' Dnawhig:0725.ME,revA.
4/6t99,,, which, is attached and reflects (lie inost recent square footage calculations.
I-IoNvever,the Building Departments of"" ross 11mm- area" seems to to
intol account the 111axinium theoretical for area achievable between the, Perimeter %valls,
As our plans, indicate, the flil arca to I)c built is, less,than 2000 square feet because a
substantial portion of the second Oocw area will he walled off by an existing, separate
structure for which there is no, ingrts's till' egi-ess on, the secund floor and there will be a
sinal ler additional area that will necessarily be left open.R)r rigging purposes an:d not
floored. Also, (he vertical electrical and mechanical chases have not been considered as,
floor area- We believe that these fiactors are different in nature froin the "hal lways, stairs,
closets", etc. that define"`net floor area", 4's rellbi-red to in Section 2.38.2, and should be
i it)i co uri tcd in the coni putation of" rosy floor area" as as hal I way or c I ose I wou I d,be.
Farthermcl,we, even if we differ on the calculation of floor area, T w(,)Uld subl-flit. that under
Section 83.2.c., a waiver of review is appropriate as, the alteration of the existing structure
will not have a significant inipad within the site or in relation to adjacent properties, the
environ.ment or any of the other factors ref"orenceld in Section 83.2.c.i. 'I'llis, will only be
an expansion, of our normal. business that is con-ently c(:,)tliduc[ed every day at this facility.

...........................
....... ... ......................
There will be no .new process,es not nornially associated with the exisLing use and
therefore nothing that would, result in any the ini.pacts referenced in. Section 8.3.2.a.fii.
Being located on the edge of an industrial area, we are keenly awire ofneighborhood
concerns and have proactively wurked with al I groups to promote han-nony and to,
ininimizetbe potential for any activity that could he of concern to our reside ntial
neighbors. For emaniple, a particular neighborhood concern is noise and in the past we
Ina ve ,worked.with the town., DEP, OSHA and local residents to deinonstrate our rtsolve
to be a good neighbor, even though sorne of our industrial neighbors,don't always share
our "going the extra mile" approac]i., We have chosen to, install roof oli sound-dt-4,deniilg
sercens, around our rooftop iiiachinery even after extensive outside coritracted sound
inortitoring ('do,eun.ients enclosed) indicaed to (Ile satisfaction of all regulatory groulps
that none was required. However, knowing that noise:is a s,ensihve issae for anyone
living in the area, we, ounitnitted as part of our current building peri-nit to again ec"MIduct
before and after sound surveys and to screen tvs necessary to, avoidincreasing sound
levels for our residential neighbors.
I raise this,issue (o enipbasi7e that ive take our responsibility of being a good neighbor
.wriously and will continue to do Y), regardless of the Board's decision on this issue.
Our (nily objection to submitting our plans, for a Planning Boardsile plan review is ti°le
tinie involved. The expansion area will be used to procluce additional pharrnaQeutical
i ngred itnts for h urn Lin c I i i i ica I tri a I s, and del ay ing co nst.rn:uct ion for several. weeks i n order
to appear before a regular rviecting of the Board will delay the conduct of those trials,,
which will have a cost that can't he nieasured in dollars and ce➢nts. We respectfully
re(ILr�st the Board to grant us, a waiver offull site plan review',
Sincerely,

SUBJECT: Environmental Sound Ms;es5menl
Dear Mr. Saulnier,
At your rcquest, Cavanaugh Tocei Associates, Inc. has pek-formed enviromiental sound
measurements in the vicinity of the Pharm-Eco Laboralories [ne. facility in North Andover, MA,
'l"he purpose of these studies was to &35ess compliance of plait Sound emissions with respect to
the Evla&%achusetts apartment of Env irojimental Protection (MDEP) Comrr unity Sourid 1.eve 1
Criteria. The, foIlowing is a discussion of appIIcable Criterla, sou kid measur'emcnts, concIuSicrxs
zmd recommmdations.
Criteria
The Mass achusetIs Department of Envimnmental Protection (MDEP) has been giveil the
>re5pc»sihiIity of es(a bi ishin g and cnfai-cir)g Tegula Ions which Iimit sound in. the envir•Canme-nt.
This agency has developed Community Sound Level Criteria that are g►aidehnee, IOr limiting
so kind at property lines and nearest affected R-esidrnces. These guidelines are as i6Ilows:

A .saw-cc uJsour?d ivilf be considered to be violating the Depaf• mew s• noise regulat ion (310-
CAIR 7,10) if the source;
I. Increases the broadband sound level by mare than 10 dB(A) above an?brer?t,
or`
2. Prodmce.s, 'pure tone" condo on - when any octave band center frequency
.somidpr•essur•e level exceeds fh,(? [wo adjacew center -equency so and pressure
fcirc{ls- by 3 decibels err• inor-c-
These criteria are measured both at the property Brie and at (fie nearest inhabite€f residence-
Ambient is defined as the background A-weighted sound level (fiat is exceeded 90% of die dine
(Lg()) measured during equipment op(-,rating hours. The ambient may also be established by other
means with the consent of the Department.
Sound Memurenient
On January 31, 1997 we performed ound measurements on the roof oftlie fac il ity and at the
sowli property line (residential properties that abut Marion Way). Figure I presents 1.90 octave
band spectra of measured background 5onnd levels at the south propefty I i n e Ioeatio?i du?-ing the
following two conditiOns:
1. All facility rooftop mi�chaniuc d equipment op-erating.
2. All facility rooftop merhanical turned off.
These data include that facility sound ern 1r,sIorn only in�r-ease background so kind leveIs by I (IBA
�froni 49 d B A to 50 dBA), In addition both spectra are void of any 1)ure tone condiiions-
Page 3
February 21, 1997
C:canclwgi ins
On the basis of these measurements we can conclude that environrticntal sounds produced by the
Pharrn-Feu facility comply with the MDEP Community Sound Laic] Criteria. Facility operatiort�
do not in-crease broadband background sound levels by 10 dBA, and the facility does not produce-
a pure lujxe coFidi#ion.
r:cornmendations
AIthongh facility sound emissions conipIy with the M D F P g€sidelines we observed that two
rooftop sound sources are audible. These sources were,
1. The compressor for the roi)ftop chiller (operates intermittently).
2. The dryer room exhaust FaB,
We boliovc that the, souxids produced by these soup ces can be significantly reduced.
To c:oritrol chiller sounds we reconimend tlxe use oIa sound barrier systeni. The barrier walls
should cover the sGuth, west and partially the east side of the chi[ler, The, barrier shOUld extend
fro in the base of tN- support frame to at toast 2 ft, above the top oFthe chiller. The barmier
materia] should have a sound absorptive face (NRC 0.95) that is oriented toward the chiller, and
a minimum sound transmission class rifting ofS`)C 30. Fat: hairier panels we recommend George
Koch Sons, Inc, 4" thiiA acQus-lic panels (available from SVA. 508/891-4009). t
To control sound prodLkeed by the dryer room exhaust Can we recorn mend the use of a larger fait
wheeI with a tower rotalion speed. This will maintain airflow but will reduce fail sound levels.
AIternativeIy, a baTier system, or an cneIosure for the fan c:an be developed,

Dear s- Colwell:
Thank you for speaking with me today, The landloi:d informed me of your call to hint
reiterating a neighbor's concern over apparent noise, possibly emanating from rnachinery located
oR trip of the huildilag at 70 Flagship Drive. We are the primary tenant in that building and as
a result of receiving this information I have initiated an investigation to address any concert.
s a first step, we have contacted the manufacturer of the, 11'VAC equipment located all tlic roof
and asked them to eo= to the site and retake reccx=eBdadons of possible ways to lower the,
normal noise oatput. Alfhough, we have lacers located at this site for several gears and e have.
not known that the Normal operating sound of building systems machinery could carry as far as
our residential n6glibors,
Th2nk you for relaying this iflforma#ior�. I will keep you informed of our irivesugati ns and of
any r,-medial action we may he ahie to take in the spirit of being a good neighbor.
Sincerely,

RE-- North Andaver Pilot Plant Environ in en tat Noise Survey
Dear Mr, Wade;
In response to your request, on November 10, 1995, an environmental noise rnonitoring survay was
cond act ed at the Phann-Eco pilot plant facility, located at 70 Flag Scup Drive in North Andover, MA.
The purpose of the survey was to determine if two of the }slant's recently inslalled roof-top screw
compressors were grncrating ambient noise levels which may constitute a noise nVisanoe issue within
the surrounding comtntrttity. BaOzgroiand information, site observations and noise- sure"y data
acquired during the North Andover visit follows.
I3atlkground Inrortmation
The Phaxm-Eco North Andover phi irmareuticsl pilot plant is situated in a smell indusOal park in
North Andover MA. its principal product consists of the manufacture of various bulls ar anio
pharmaceutical, low molecular weight compounds that use used by private, commercial and federal
medical laboratories, in the pursuit of new drug product res ch_ The plant occupies 11,100 square
feet of work space within a wilding shared by 4 other businesses, The North Andover site employs
19 staff members, conslstirkg of managers, chemists and technical personnel. The plant started
operations approximately 23 niGnths ago, and has keen fully operational since My of this year. In
July, 1995, two screw typo Trarte 114, aEr rel`rigeration compressors were niminted on the roof of thle
building. When the compressors came on line hitermittenEly, there was &erne question about of the
emiount of noise these units could generate during continuous operation. Maragcmtnt deterrriitied
when both compressor units were operating at peak, ;in environmerital noise sury + of the
equipment's noise oistput and surrounding properties, should be undertaken.

Site Observations
The Pharm-Rco pilot plaint as mentioned, is located within a small industrial park, allotted near sirl,&
family privatto dwellingg, which are located on Rn adjacent roidcntial street. The closest ra~ idential
homy is located approximately 300 yardg ftom the rear of the building in question. There is a wooded
boundary wW ch separates the commercial and resi dent W houses. At the tune of tht noiso 6urvey, the
trees and busies within the boundwy were barren of leaves. Thai day was clear, the outside
ternpcm(ure was at 41 OF, end the wind dirocticn wa i;from the northwest at approximately 5 Mph.
Survey Mtthodalogy
The noise survaty was conducted using aCOL-254, type 2 Sound Levi Dieter(SLM), wNch hind Won
pre-calibrated (and later post calibrated) using n CEL482 acoustical calibrator. An open cell wind
screen filter was used on the SLM microphone in order to reduce wind noise influence. Noise
measurements were to k-en vn "fix and " " weighted atvcWe sound levels, using the slow rmaponw
mode where noise is Tnearsu red in dwsbels(4R), cithet dBA or dB ,
The W ac.ale more accurately represents human noise perccptlov4 as this scale is prejudi #award
the higher frequency levels ( 00 to S,000 Hertz). The H x stale mewlaremetats on the other band, are
prejudiced toward the lower frcqu cy levels{50 to 500 Hertz). Noigo is considered to be"unwanted
sound", and is ai mixture of both low and Ngh Frequencies. In the work crivironrncm, high noise levels
ere consides'ed to be an occupational hazard,
Tht US. Department of Labor, Occupational Health and Safety Administration (OSHA), rrgulaW
work environment noise cxposures and considers =ployees who.are exposed to noise In excess of 85
(dBA), in an 8-hour work period as a having a potential for hearing lou, In the gmral (outdoor)
environment, noise generated by motor vehicles, planes, wind, insects, etc., all conlribute to overall
noise levels. It is slot that unusual to have noise levels within cerwa Sections of a busy city to easily
exc od QSIWa work environment exposure limit of SS decibels in an 9-hour period,
The Federal EnviroMp-,ntal Pratcction Agency (EPA) considers continuous sontrd energy of 574
decibels over a 24-hour period, (outdoor environfrk rat) as a potential for hearing loss. The ag-ency
also considers an outdoor noise la:vels (nighttime) of!05 decibels S-hours in duration, m a nuisance_

Noise survey locations and mcssurerneuts that were aquired accompany this report,
Rdcnrrrrnen�alionE
The two roof-top air reffigeration compressors generated noise which was in tho Wg nr &equency
ranges. High frequency noise lends to he linear in its travel, and is easier to control than those of the
iowef ftequcncY variety. It nsay be possible to instsfl a closed cell foam blanket in front orthcsa two
Imits which could further reduce their imvirorfinent$L noise output by several decibels_
