III. Inspection Findings
According to the facility PCB Annual Reports, and based on in
spection of the plant, there were four PCS trans formers, and an unknown
number of mineral oil transforrrers in service at Aerovox Industries, Inc.
There were also three PCB capacitors stored for reuse. The facility has
purchased millions of pounds of PCB Arcclor from yonsanto in the past (See Attachments 1 and 2) . The NPDES water discharges, the former PCB
impregnation tanks, and the capacitor casing degreasing operation were all
irr.-r.-.- .1- • "ra < 7 \irir.'-; the iiv-;-----icn.
All four of the PCB transformers, and five mineral oil transformers
were observed by the inspectors and are cercribed in Table 1. The facility
is in the process of reclassifying three of its PCB transformers by
refilling the transformers with KTBrp fluid and filtering the fluid for
residual PCBs, using an EPAC filter system. The two General Electric PCB
trans formers, which have been using the EPAC filtering system since
2/15/81, do not have the ML PCB labels affixed to them. These
transformers have not been tested for PCB concentration since the EPAC
system cttimenced operation. The third transformer which is using the EPAC
filter system, is a Westinghouse trans former, and it has an ML PCB label
affixed. According to the most recent PCB Annual Report for the facility, " •
the fourth PCB transformer, is located in the backyard substation (See *i.
Figure ] / . The nameplate of this ?i -svated transformer could not be read to ?
verify whether it was a PCB transformer, and the unit was not rrarked with ^
the ML PCB label (See Table 1 and Attachment No. 4). vj>
There were three Cornell-Dubilier large, high-voltage PCB capacitors
in the machine shop on the third floor of the main manufacturing building.
Mr. Butterworth stated that these units are stored for reuse in electrical
equipment. All three were marked with ML PCB labels and were not
leaking. According to Mr. Butterworth, there are no PCB capacitors
remaining at this facility from the previous PCB capacitor manufacturing
operations. Aerovox discontinued the manufacture of PCB capacitors in
October 1978.
Aerovox Industries, Inc. is using dioctyl phthalate (DOP) as a
substitute for Askarel in many of their new capacitors. An oil sample was
collected from Impregnation Tank No. 3, from which capacitors were
currently being filled with DCP. Sb PCB contamination was detected (See
Table 2). In the past, capacitors were filled with Askarel that was stored
in this same impregnation tank. No PCB testing results could be furnished
by Mr. Butterwcrth regarding the PCB ccr.cor.traticn of the fluids in the
impregnation tanks, or bulk DOP storage tanks, since tine PCB fluid was
removed from the system.
Aerovox Industries, Inc. had previously purchased millions of pounds

PCBs have been discharged chrcuch the two LCPCSS outfalls (C01 and 002) into
the Acoshnet River. Aerovox Industries, Inc. has installed a water
recirculation system at their plant, and now rarely discharge effluent, and
vAien, only through Outfall C01. Acushnet Ccrcany leases property frcm
Aerovox Industries, Inc., and currently contributes almost all of the
effluent water which leaves the Acushnet facility through Outfall 002.
Oil-impregnated soil was observed in the culverts leading to and at both
outfalls (See Photographs in Attachment B). Five soil samples were
collected associated with Outfalls 001 and 002. Locations are sho-. n in
Figure 1 ^nd -che PCB analytical results are reported in Table 2. PC3
analytical results of these five sampling points range from 40 ppm to
23,000 ppm PCB Aroclor 1242.
A soil sample was collected frrTn a stained area in the backyard power
substation (See Photograph tfo. 5). A concentration of 24,000 ppm PCBs was
found in this sample (See Table 2). According to Mr. Oakum of the U.S.
EPA, this area was used for drum storage within the last month.
Aerovox Industries, Inc., had a capacitor casing degreasing operation
utilizing trichloroethylene (TCE) as the degreasing solvent. Degreasing
residues (still bottoms) from this process are stored in 55-gallon drums in
an undiked room which has a concrete floor. Three full 55-gallon drums
with black on red hazardous \.aste labels, but no t^ PCB labels, were
observed in this storage area. An oil sample collected from one of these
drums revealed a PCB concentration of'170 ppm (Table 2) . According to Mr.
Butterworth,-the facility generates approximately one drum per weak, and
disposes of the drums through Recycling Industries. Mr. Butterworth also
stated that Aerovox Industries, Inc. occasionally collects composite
samples frcm these drums, and tests them for PCBs. PCB concentrations in
excess of 50 ppm have been found. Mr. Butterworth did not furnish the
inspectors with prior sample analyses for PCB testing from this degreasing
process.
The waste oil storage area was located in the basement of the Main
Manufacturing Euilding at Aorcvox Industries, Inc. (See Figure 1).
Approximately tv.-enry 55-gallon drums cf ncn-reclalTable COP and compressor coils are stored for disposal ~-> -Billets -hr-,*« a cr*r-!+- floor. All c the
<J:-~_ • .- > •_'• N . o'. ... 1 .. „ . ,vC_< . l.ij area is
not diked, and there are no M^ PCB labels on the dru.r.s. A sample frcrn >•.
one of the drur s, which contained non-rcciai:r.3ble r:CP , was collected and
showed no PCB contamination (Table 2).
The facility has a 14 x 14 foot PCB storage area, with a six- inch
concrete curb containment wall, and a concrete floor. No PCB articles were
in the storage area at the time of the inspection. Ihe storage area was
narked with the ML PCB label. Most of the PCB articles previously in
storage at Aerovox Industries, Inc., have been hauled to Recycling
Industries, Inc., in Braintree, Massachusetts, where they are being stored
and are awaiting disposal at an approved site. A disposal invoice for
Aerovox Industries, Inc. is shown in Attachment No. 5. The previous
disposal of a PCB transformer on 12/28/79, and the separate disposal of its
1750 kgs of PCB fluid, are explained on Page 2 of Attachment No. 4,
Aerovox Industries, Inc. had PCB annual documents for the 7/1/78 to
7/1/79, and 7/1/79 to 7/1/80 reporting years (See Attachments 3 and 4) .
These annual documents pertain only to electrical equipment and are not
summarized on a standard calendar year basis.
According to Mr. Butterworth, there were no hydraulic systems which
contain more than one quart of hydraulic fluid at Aercvox Industries, Inc.
and that press machines • ;re electric-powered at this facility.
IV. Facility Description
Aercvox Industries, Inc., is a capacitor manufacturer, which produces
paper, paper oil, electrolytic and mica capacitors. The facility manu
factured PCB capacitors from 1947 to 1978. The plant employs approximately
850 people, and is in operation 24 hours a day, seven days a week.
Presently, Aerovox Industries, Inc. leases some of their property to
Acushnet Company for their own capacitor manufacturing operation.
The site of the present plant was formerly a terctile mill since 1921 .
In 1938, Aercvox Corporation bought the plant and moved its capacitor
operations from New York City to New Bedford. On January 1, 1973, the
facility was sold to Belleville Industries, Inc., which subsequently
changed its name to Aerovox Industries, Inc. This facility is a subsidiary A
of FTE Corporation of Waukesha, Wisconsin.
V. Inspection Surtrary
The inspectors arrived at the facility accompanied by the EPA
personnel on the iteming of June 18, 1981, and met MX. Tut tie, and Mr.
Butterworth. Mr. Tuttle was presented with the inspectors' credentials, a
"Notice of Inspection" and a "Notice of Confidentiality." Mr. Tuttle
signed both notices and returned them to the inspectors. The EPA personnel
seeing that the inspectors had no problem with entry* left the facility.
The inspectors cartnenced their visual inspection of Aerovox
Industries, Inc. at the capacitor fluid-filling operation, where they
collected an oil sample from Impregnation Tank >XD, 3. The inspection team
next stepped outside where they sampled and photographed NPDES Outfalls
001 and 002, as well as culvert 002. The inspectors proceeded to inspect
the PCB transformers at the facility and documented their findings in Table
1 of this report. The inspection team moved to the TCE still betters drum
storage area, where they collected an oil sample from one of the drums.
The inspectors again stepped outside and proceeded to collect two soil
samples fron culvert 001. Finally, the waste oil storage area and the PCB
storage area were inspected and documented.
The inspectors returned to Mr. Butterworth's office and presented him
with a "Receipt for Samples and Documents." He signed the receipt and
returned it to the inspectors. The inspectors requested copies of PCB
sampling analyses for the TCE degreasing operation, and the former PCB
filling operation. Mr. Butterworth said he would try to obtain copies of
these analyses and mail them to the inspectors. To date this information
has not been received.

Dear Mr. Miller:
As requested in Mr. Legro's letter of August 16, 1975, we haveanswered the questions to the best of our ability. In addition, thefollowing information about our company and its use of PolychlorinatedBiphenyl (PCB) may provide useful background and perspective.
Aerovox Corporation (now AVX Corporation)was a manufacturer ofcapacitors for approximately 50 years. In 1938 that company movedfrom New York City to New Bedford and housed its operation in aformer textile mill on the shore of the Acushnet River, which is atidal estuary at this point. The New Bedford operation manufacturedseveral categories of capacitors including Paper, Paper Oil, Electrolytic and Mica Capacitors. In 1947 it commenced using Aroclor (whichcontains PCB's) as an impregnating fluid for paper oil capacitors because of the exception stability of this material and insurance company and building code requirements that flammable fluids are notallowed in capacitors used in building. These same qualities arestill required to produce a dependable, safe and low cost capacitor.The early Aroclor compounds were not readily biodegradable, whilesubsequent compositions (including Aroclor 1016 which is currentlyused) are considerably more benign in this respect.
On January 1, 1973, Aerovox Corporation sold its New Bedfordfacility to a new group which was, for a brief period of time, known.as Belleville Industries, Inc., and subsequently as /Acrovox Industries,Inc. The new owners have shown a keen awareness of their environmentalresponsibilities and have instituted Aroclor containment and incineration procedures. A copy of' this Aroclor Handling Procedure is enclosedfor your information (See Exhibit A).
All Aroclor utilised ovox r i~r. is purchase .1 from the
usage hus averaged in excess of 1,000,000 pounds per year, pro.Vxv.i-nantly of the Aroclor 1016 compos it. ior.. In addition, relatively srrallamounts of Aroclor 1254 are used, primarily in the impregnation ofcapaci Lore.- for the Zicurvhr.jt Capacitor Ccr.-.pany and for the manufactureof D.C. capacitors used primarily by the U.S. military. 7s.rcclor 1242was used during 1971 before the more biodegradable 1016 became available.
The bulk of the Aroclor purchased leaves the plant in sealedmetal cans in the form of finished capacitors being shipped to customers. These cans and covers are generally made of .015" steel althougha small number are made of aluminum. The cans and covers are roll-sealed together with a cover-sealing compound material, and then impregnated with Aroclor through a small fill-hole. This fill-hole isthen sealed with a silicone bung insert, or by soldering. Thesefinished assemblies are subjected to high temperature tests to identify, cull out and reseal any leaking units. As a result, capacitorsshipped into the field very seldom leak.
All Aroclor which drips off the units, the impregnation basketsand the degreasing baskets during the manufacturing cycle is caughtin drip pans and stored in steel drums and accumulated for incineration. When a quantity in the order of 40,000 pounds is accumulated,it is shipped out by tank-truck to an incineration facility approvedby the State of New Jersey. In the past three years, Aerovox sentout an average of more than 100,000 pounds of Aroclor per year forincineration. Prior to this time nc Aroclor was sent out from thisfacility for incineration.
s:Sealed units that are rejected for various reasons are disposed oin an approved sanitary landfill site in New Bedford by a disposal contractor.
Aroclor also leaves this plant by the discharging (in suspensionwith cooling and sewage liquids) of extremely small quantities intothe Acushnet River and the New Bedford sewer system. These small discharge amounts are unavoidably included in our cooling and sanitaryliquid discharges and are in the low parts per billion level whencombined with other liquid discharges. Based on analyses of both continuous and grab samples of our cooling water discharge, the amount ofPCB's reaching either the Acushnet River or the city sewer system isso small as to be difficult to measure. This is due to the in-plantcontrols instituted under the enclosed Aroclor Handling Procedure andthe increased concern of the new owners and management. All of ouranalytical work has been done by laboratories either at Monsanto, orat a Monsanto approved independent laboratory (Woodson-Tene it) in
I'cmphir;, Tennessee. In several cases identical samples were analyzedby both laboratories and the partr, per bill Jon (PP~;) findings ve^-ecompatible.
The specific answers to your questions are as follows:
1. Not applicable
2. a) Aerovox Industries sole product is capacitors which areused in a wide variety of electrical applications rangingfrom ballasts used in fluorescent light circuits to atomicenergy research. Each capacitor is a closed system thathas no inherent means of dispersing impregnating fluidsinto the environment.
The physical size of the product ranges from units ofapproximately 1 cubic inch to units of 5,000 cubic inches.There are also wide variations in capacitance; and voltageratings of the units.
b) The following table shows the estimated total amounts ofAroclor 1242, 1016 and 1254 which have been incorporatedinto our product for the years 1971, 1972, 1973, 1974 andfor the first 6 months of 1975. This table was compiledfrom records of Aroclor purchases, capacitor productionand the incineration of scrap Aroclor. Because numerousrecordkeeping changes preceded and followed the advent ofAerovox Industries on January 1, 1973, it has been necessary to some- degree to interpolate and extrapolate fromthe documents available, making every effort to maintainarithmetic integrity in the process.
SOURCE DERIVATION FOR 2D TABLE
1) Aroclor Purchases - obtained from Purchasing records.
2) Inventory adjustments are based on physical inventories at, orclosest to, end of each period. (See attached Exhibit B ).
3) Scrapped unit Aroclor weight is based on reject test data for 1973,1974 and 1975; csti:.u'ted for years 1973 and 1972. Number of unitsscrapped is extended by the Aroclor content of representative unitin each size category. Aroclor contort is obtained from bill-of-material specifications. (See attached Exhibit C illustratinghow 1973 figures were obtained).
