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.

INDUSTRIES, INC. New Bedford, /.'.cos. 02741

617-994-S661

September 29, 1975

Mr. Jeffrey Miller.Director, Enforcement DivisionEnvironmental Protection AgencyJohn F. Kennedy Federal Buildingboston, Massachusetts 02203

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).
