McGraw-Edison switches
--PCBs to Edisol
COLUMBIA (AP) - A company that produces high-voltage power capaci tor* for electric utilities
tald today it wtu stop Uflng PCB insulating fluid Nov. I, and will convert to' a more environmentally ale fluid named Edisol.
Officials of the McOrawEdison Co. made the an
nouncement at simultane ous news conferences In
Columbia and at company
headquarters in Pitts burgh, Pa. The company
has a South Carolina plant in Greenwood.
R.H. Keith, general
manager of the Greenwood plant, said in Columbia that Edisol, developed by
the Dow Chemical Co., costs about 29 per cent more than PCBs (polychlo rinated biphenyls), but has a longer life and is less hazardous to the envi
ronment. Cost of conver
sion will be "several hund reds of thousands of dol lars,'* he said. "We are
firmly convinced Edisol
can do a better Job than PCBs"
Some are in use now, he
said.
There have been reports in South Carolina. Georgia and other areas or high levels of PCBs in water ways. There have been warnings from health offi cials that eating fish taken from Lake Hartwell, lo cated on the South Carolina-Georgia line, may be hazardous to the health of humans.
Keith said PCBs began to be seriously suspected of having undesirable cha racteristics in 1970, lead ing to research into safer
fluids.
Some persons who have been exposed to PCBs
have developed a skin rash, but more than that, there is some concern they may cause birth defects and cancer, he said.
McGraw-Edison's cus tomers are utility compa nies such as Duke Power Co., based In charlotte. N.C., but serving a large
portion of upper South Ca
rolina, and South Carolina Electric and Gas Co.
Earlier this month a SI billion suit was filed
against the Monsanto _Co7
of St. Louis, Mo,, and the
Swttamq. Electric Cp. of
Pickens oh behalf of Lake
Hartwell property owners
In Georgia and South Ca
rolina.
Monsanto was accused
in the suit of negligence
and "strict liability" in Its
production of PCBs, ac
cording to Ronnie Cole, a
member of an Anderson
law firm which filed the
complaint.
.
Cole said Monsanto pro
duces PCBs used by Sang-
amo In its manufacture of
electrical
capacitors.
Sangamo has been identi
fied as a source of PCBs
found in Lake Hartwell.
The suit says the PCB
contamination has caused a lowering of property
values and a loss in profits
to businesses along the
lake.

Keith said the Initial
reaction to Edisol among
McGraw-Edison's utility
company customers has
been good, but there is
still wide use of PCBs.
Also, he said. Jhe fed
eral EnvironmentAL^Pro
tection Agency seems to
like the new insulating
fluid. He said the EPA
does not have the authority
to approve Edisol's pro
duction, but could ban its
use if U were deemed
harmful.
Keith said the EPA
regulates the amount of
PCBs that may be dischar
ged by electric plants. He
said the Greenwood plant
has never been accused of
discharging
harmful
amounts of PCBs.
Keith said there are
some economic risks invol
ved in the changeover if
Customers continue to ask
for PCB power capacitors,
which also are manufac
tured by Sangamo, Gen
eral Electric and Westing-
house.
The motivation for the
change "was the recogni
tion in 1970 that this
(PCBs) would become an
increasing
problem--
which it has," Keith said.
Rather stringent meas
ures were taken to mini
mize the discharge of
PCBs when the GrecnwoiKl
plant was built in 1973.
