5 DIRECT EXAMINATION
6 QUESTIONS BY MR. BRADLEY *
7 Q. Would you please state your name.
8 A. John H. Craddock. o Q. And would you spell your lastname?
10 A. C-r-a-d-d-o-c-k.
11 Q. Dr. Craddock, you're here today as a person
12 designated by Monsanto Company to give testimony in the
13 case of Nevada Power Company versus Monsanto, General
14 Electric, and Westinghouse, as the corporate designee, to
15 discuss those topics contained in Attachment A, subject to
16 a time limitation, as I understand it, and I have had
17 marked for identification as Deposition Exhibit 1 the
18 notice, along with the attachment, that has the topic for
19 today's deposition. 20 You're here today represented by Scott Bauer;
21 is that correct?
22 A. Yes.
23 MR. BRADLEYr Mr. Bauer, will you indicate for
24 the record what areas the witness is being tendered on and
25 for what time periods.

1 MR. BAUER: Attachment A for the time period
2 from the beginning of 1976 essentially through the present, 3 although I believe Dr. Craddock's official retirement date
4 is in January of 1993.
5 MR. BRADLEYi It is my understanding that Mr.
6 Papageorge just testified to 1976 , not through 1976. Am I
7 incorrect in that?
8 MR * BAUER: Yes, I think so. Sometime in
9 January or February of 1976 -- Mr. Papageorge's testimony
10 is whatever it was. Sometime in that time period he left
11 his responsibility as being directly responsible for PCB
12 matters, and it's our intention to have Dr. Craddock to
13 pick up from that time period. Whether it's January or
14 February of ' 76, it's that basic time period.
15 Q. (by Mr. Bradley) Dr. Craddock, you received
1C your doctorate in 1961 from Vanderbilt University; is that
17 correct?
18 A. That's correct.
19 Q. And did you receive your doctorate in inor
20 ganic chemistry?
21 A. Yes.
22 Q. Is inorganic chemistrychemistry primarily of
23 mostly noncarbon atoms?
24 A. Yes.
25 Q. And following completion of your doctorate

1 degree, you worked for M.W. Kellogg Company in New York
2 City; is that correct?
3 A. That's correct.
4 Q. You worked there from1961 to1965?
5 A Yes
6 Q. And while you were there you worked in their
7 corporate research department as a research chemist,
8 research specialist; is that correct?
9 A. Right. Varioustitles atthat time.
10 Q. While at M.W. Kellogg Company you were study
11 ing exploratory chemistry of precious metals as a liquid-
12 based catalyst for petrochemical reactions?
13 A. That's correct.
14 MR. BAUER: Excuse me, Mr. Bradley. Mr.
15 Fapageorge was designated with a cutoff date. As we
16 discussed, there is an opening issue about whether he was
17 also covering health hazards to humans during that time
18 period. He was originally designated and then withdrawn,
19 and Dr. Craddock is picking up at that time period,
S\. '
20 covering human health hazards as well as environmental
21 matters. Do you understand what Is saying?
22 MR. BRADLEY: 1 understand what Dr. Craddock's
23 testimony covers on Attachment A,

5 Q. (by Hr. Bradley) And the work you did at the
6 Kellogg Company did not involve any products containing
7 polychlorinated biphenyls?
8 A. No, it did not,
9 Q, And you began your work with Monsanto Company
10 in 1965?

25 research specialist, you used a fume hood; is that correct?
-7-
CONCANNON & JAEGER
WATER PCB-00049979
COMPUTER AIDED TRANSCRIPTION
1 A. That's correct.
2 Q, What is a fume hood?
3 A. It's a standard piece of laboratory apparatus
4 that's like a cover that you can close the doors or
5 restrict the access. It has negative pressure so that any
6 fumes from reactions to vapors would be kept within the
7 fume cover. So if you do any type of reactions that
8 involve volatile chemicals, they will not get into the
9 whole laboratory or office part of the facility. They're
10 vented separately from the building.
11 Q. Did the fume hood when you used it in the lab
12 prevent the vapors from the chemicals from entering your
13 system?
14 A. Yes.
15 Q, Is the purpose of a fume hood -- Was the
16 purpose of the fume hood to protect you from breathing the
17 vapors and to prevent the vapors from entering the work
18 place?
19 A. Yes. it's a standard piece of operating
20 equipment in a lab,
*> '
21 Q. You then began working as a senior chemist,
22 research -- Excuse me. In your career at central research
23 you were a senior chemist research specialist and a
24 research group leader? is that correct?

2 merit unti 1 roughly the 1971 time frame?
3 A. That's correct.
4 Q. And during that period of time you were either
5 managing or doing exploratory research?
6 A. That's true.
7 0. And the research you were doing related to
8 precious metals catalysts?
9 A. Yes. That's correct.
10 Q. In 1971 you became a supervisor of commercial
11 development?
12 A. Yes.
13 Q. And in that job are yourfunctions to transfer
14 successful research projects to one of the operating units
15 of the Monsanto Company?
16 A. That1scorrect.
17 Q. And none of thoseresearchprojects involved
18 products containing PCB's?
19 A. That's true.
20 Q. You then transferred to the Monsanto
21 Industrial Chemicals Company as a manager of commercial
22 development, in the food and fine chemicals division,
23 primarily dealing with food preservatives; is that correct?
24 A. That's true.
25 Q. And that occurred in roughly the '74 time

2 A. That's true.
3 Q. And in that job you were not working with
4 products that contained PCB's?
5 A. That's correct

7 operations, which was a newly-formed operations department
8 of the Monsanto Industrial Chemicals Company; is that
9 correct?
10 A. That's correct.
11 Q. And in that job you did have contact with
12 Monsanto products containing PCB's?
13 A. Yes.
14 0. in that job were you responsible with com
15 pliance with regulations which were promulgated under the
16 Toxic Substances Control Act?
17 A. Yes. Those regulations came into affect from
18 '78 forward.
19 Q, During the time that you had that job did all
20 of Monsanto's plant operations have large amounts of
21 electrical equipment which primarily contained PCB's as a
22 dielectric fluid component of the electric power distribu
23 tion system?
24 A. Yes.
25 0. And you had that jobuntil 1980?

1 A. Yes.
2 Q. In 1980 did you become the corporate focal 3 point for PCB issues at Monsanto where you answered PCB
4 questions, monitored PCB regulations# provided corporate
S responses to regulatory agencies# including questions in
6 the Federal Register# and answered customer questions and
7 calls and so forth?
8 A. Yes.
9 Q. And you had that job until your retirement in
10 January of 1993?
11 A. That's correct.
12 Q. And the job that you had between 1980 and 1983
13 did not exist before you got that job in 1980?
14 A. Not in that form, no. 15 Q. And the title of the job you had in 1980 was

18 Q. Did you review any documents in preparation
19 for today's deposition? 20 A. Yes.
sf '
21 Q. What documents did you review?
22 A. I reviewed some of the health effects studies,
23 roughly the time frame, some of the same material that I
24 viewed prior, for my prior deposition, just to refresh my
25 memory on the chronology of when papers were published, and
- 11 -

so forth.
Q, So you reviewed the prior depositions you have
3 given in this lawsuit?
4 A. Or the material that was used in those deposi
5 tions , yes. Not the depositions, per ae? but the material
6 that was used in preparation.
7 Q, Did you review the depositions? as well?
8 though? in addition to the materials?
9 A. No.
10 Q. In March of 1976 did you have any responsi
11 bility for any Monsanto products containing PCB'o?
12 A. No,
13 Q. Your first responsibility for working with any
14 products containing PCB's began in 1977?
15 A. That's correct.
16 Q, Okay. During your employment at Monsanto, did
17 you ever review any compilation of studies, reports, and
18 other similar kinds of information? that cataloged? as of
19 March of 1976? the dates and substance of Monsanto's *. *
20 acquisition of notice and/or knowledge concerning any and
21 all alleged potential or actual hazards of RGB's or mono-
22 chlorinated biphenyls?
23 A. No.
24 Q. Do you know whether in March of 1976 such a
25 compilation of studies or reports existed?
- 12 -
CONCANNON & JAEGER
WATER PCB-00049984
COMPUTER AIDED TRANSCRIPTION
1 A. It did not/ to my knowledge.
2 Q, Are you able to tell us what information or 3 studies regarding any and all alleged potential or actual
4 hazards of PCB's or monochlorinated biphenyls Monsanto
5 learned between March of 1976 and 19777
6 A. I can recall the landmark papers and review
7 studies/ I think/ that have been published/ that I read/
8 that were available.,
9 Q. As I understand your testimony, some studies
10 became available during that time and you are able to talk
11 about the studies that you know of that were published
12 between March of 1976 and 1977; is that correct?
13 A. Well/ I can recall/ as I saidf the landmark
14 studies/ and I can probably tell you the gist of some of
15 the information without having the paper in front of me,
16 but I can't discuss the complete study in detail.
17 Q. All right. And it wasn't until 1980, was it,
13 that you made an effort to collect information which sum
19 marized Monsanto's known information about PCB's and PCB
20 issues?
f-K ' '
21 A. That's correct
22 Q. Why did you collect information in 1980 which
23 summarized Monsanto's known Information about PCB'e and PCB
24 issues?
25 MR. BAUER: Object to the form of the ques-

CONCANNON & JAEGER
WATER PCB-00049985
COMPUTER AIDED TRANSCRIPTION
1 tion. Vague,
2 Q. (by Mr. Bradley) You can go ahead and answer
3 now,
4 A. I was newly appointed to a new position# and
5 one of the first tasks that I deemed that was important to
6 do was to review all of the information that I could find
7 from the published literature# from Monsanto files# from
8 anywhere# to learn about PCB's*
9 Q, And did you present that information in a
10 summary report that was provided to Senator Ekhart's
11 committee?
12 A. I did not do that. That information was put
13 together -- I think that testimony was probably presented
14 to the Ekhart Committee in 179# but that was the -- the
15 body of information that bad been assembled was one of the
16 files of information that was at my disposal to review the
17 history of PCB health effects and the history of Monsanto's
18 activities with PCB,
19 Q. I want you to be as specific as you can be in
20 recounting for me where within Monsanto you turned to
21 gather information which summarized Monsanto's known
22 information about PCB's and PCB issues,
23 A, The first thing I did was# I went to the
24 Monsanto library and did a chemical abstract search for
25 published reviews and surveys and summaries of PCB
** 14 -
CONCANNON & JAEGER
WATER PCB-00049986
COMPUTER AIDED TRANSCRIPTION
1 articles.
2 Q. is the Monsanto library different from the
3 library in Monsanto's medical department?
4 A. Well, Monsanto medical library is part of the
5 Monsanto's library system. Sometimes they call it the
6 Monsanto Library System, sometimes they call it the
7 Monsanto Information System; but it1s all one library, just
8 different parts are located in different buildings.
9 Q, When you did the chemical abstract search, was
10 that in Monsanto*s Information Center or Monsanto's medical
11 department library? 12 A. This was done at the Information Center, which
13 is the master library, has the master catalogues.
14 Q, what did you receive as a result of your
15 access to the chemical abstract search?
16 A. A couple of the major documents that I recall, 17 which are the standards, one is the very recent 1979 mono
18 graphed by the National Academy of Sciences, entitled
19 "Polychlorinated Biphenyls,* which detailed the significant
f-0 *
20 published environmental health effects in animal testing up
21 until its publication. Another document that turned up was
22 a document called -- I think it was called the "Report of
23 the Interagency Task Force on PCB's, which was published
24 in May of 1972. This was the earliest summary of history,
25 usee, known health effects and environmental effects and so
- 15 -
CONCAMNON & JAEGER
WATER PCB-00049987
COMPUTER AIDED TRANSCRIPTION
1 forth of PCB's. Those were the two major documents that
2 turned up at that time.
3
In addition, I was able to
through reading
4 just some of the files and information, I learned of the
5 Bkhart Committee submission and was able to get a copy of
6 that, which was available.
7 Q. 1 am not familiar with the chemical abstract
8 search system, is that a system that allows you to make
9 entries on a computer systems by topic?
10 A, It is today, yes. You can -- It's a very
11 sophisticated search. You can put together chemicals, 12 words in a title, authors, dates and so forth.
13 Q, And how did it function when you used it in
14 1980?
15 A, In 1980 it was a computerized data base,
16 Q. And did you punch in, then, the topic,
17 "PCB's"?
18 A. I did not do that; I had this done. I called
19 the information center. We have information specialists,
20 and you sort of give them a summary of what you're looking
21 for, articles on PCB's related to health effects, and so
22 forth. Primarily summaries and review articles is what I 23 asked for rather than dozens and dozens of individual
24 articles, I was looking for surveys, and particularly the
2 5 moot current surveys that had the latest information and
- 16 -
CONCANNON & JAEGER
WATER PCB-00049988
COMPUTER AIDED TRANSCRIPTION
1 covered the broadest period of time, up to the latest*
2 Q. In response to your request to the Information
3 Center, did you receive the two reports that you mentioned,
4 the National Academy of Science's report and the Inter
5 agency Task Force report, or did you receive a printout
6 that listed different documents, or did you receive some
7 thing entirely different?
8 A* I don't recall specifically, but many times
9 this comes back as a printout, and then you can circle
10 articles that you want, and if they have them in the stacks
11 or in the reference books, they will provide you with
12 copies of articles, or else you can have them ordered. So
13 I probably used some of all of the techniques above to
14 obtain the information.
15 Q. And you indicated that you also went into the
16 files and other information to learn about the Ekhart
17 Committee submission. Which files did you locate that
18 submission in?
19 A. 1 don't recall how that turned up, whether it
20 turned up on the list or whether it was a -- it was a pub
21 lished document. There were a lot of government documents
22 and public domain documents that turned up. For instance,
23 another major document that turned up was a document known
24 as the Versar Study, which was -- Versar was a contract
25 research organization which had been commissioned by EPA to
- 17 -
CONCANNON & JAEGER
WATER PCB-00049989
COMPUTER AIDED TRANSCRIPTION
1 essentially do a total history of what is known about
2 PCB's, everything from uses to health effects and
3 environmental effects and so forth.
4 Q. Including information regarding imports and
5 exports?
6 A I don * t know what they had about imports or
7 exports, but Monsanto contributed to the Versar document,
8 For instance# Monsanto made available its production and
9 sales figures. Those numbers in the Versar study come
10 directly from Monsanto. If you compare that with the
11 Ekhart thing, you might not get the curves and graphs and
12 such, but that was available.
13 0. Did you request any information from
14 Monsanto's medical department in your effort to collect
15 information which summarized Monsanto known information
16 about PCB`s and PCB issues?
17 A. Not at that stage# no. I was looking for
18 published information# reviews# summaries of PCB informa
19 tion.
20 Q. Did you ever request that 'anyone within the
21 medical department of Monsanto provide to you information
22 which summarized Monsanto 1 a known information about PC31s
23 and PCB issues?
24 MR. BAUER: Objection. Vague as to the use of
25 the term "information which summarizes information."
- 18 -
CONCANNON & JAEGER
WATER PCB-00049990
COMPUTER AIDED TRANSCRIPTION
1 But you can answer.
2 A. I don't recall specifically. Some of this
3 information that you are talking about was summarized in
4 the Ekhart Report. There was a summary document in the
5 Ekhart Report that Monsanto subsequently published. It was
6 referred to as the white paper, because it was a white,
7 sort of plastic-covered, booklet with black letters, of
8 Monsanto * s PCB uses, I've forgotten the exact title. This
9 document, which was an overview summary to the Eckart
10 report had this information summarized $ What tests had
11 been done, what types of feeding tests had been done by
12 Monsanto, what significant tests had been published in the
13 literature. And I guess probably the publications went
14 from about '77 or '78. At this time it included what was
15 known about scientific studies that were in progress but
16 not yet published, and so on and so forth. This informa
17 tion was already summarized. I guess it had been done for
18 the Ekhart thing.
19 Q. (by Mr. Bradley) I appreciate the depth of
20 your response. I am not certain, though, that I got an
21 answer to my specific question, which was intended to be,
22 between 1980, when you began collecting information, and
23 your retirement, did you ever request anyone within
24 Monsanto's corporate medical department to provide you with
25 any information regarding Monsanto`s knowledge about PCB1s
- 19 -
CONCANNON & JAEGER
WATER PCB-00049991
COMPUTER AIDED TRANSCRIPTION
1 and FCB issues?
2 A. I guess I don11 understand the question,
3 still. I thought you asked me if anybody had --- if I had
4 asked anybody to provide a summary of information. I asked
5 for specific information from time to time, yes, but I
6 didn't ask for any summary of all information
7 Q. All right. Then between 1980 and your retire
8 ment you did not request a summary from the medical depart
9 ment of the information that was known to Monsanto about
10 the actual or alleged or potential hazards of PCB's?
11 A. Again/ I guess I don't understand the ques 12 tion. There were specific things that I asked fori and
13 when l would ask for information, then they would provide,
14 or answer the questions.
15 Q. Well, then let me try to make the question a 16 little clearer to you.
17 A. Break it down or something.
18 Q. In 1980 you collected information which sum
19 marized Monsanto * s known information about PCB's and PCB
20 issues, correct?
'
21 A. Yes, along with everybody else's.
22 Q. As part of that effort did you request that
23 Monsanto * s corporate medical department provide you with 24 summaries about what was known about the potential or
25 alleged hazards of PCB's and PCB issues?
- 20 -
CONCANNON & JAEGER
WATER PCB-00049992
COMPUTER AIDED TRANSCRIPTION
1 A. In 1980 I did not.
2 Q. Did you request that information ever from 3 Monsanto's corporate medical department? The summary, I'm
4 talking about.
5 MR. BAUER* I think it's still vague. I mean,
6 I don't understand the use of the word "summary in this
7 context.
8 THE WITNESSi Can I say something.
9 MR. BAUERj No. Because any --
10 Well, is this like a bibliography, a purported

12 a particular paper, all of which would fit easily within
13 the definition of the word "summary."

15 pared to define "summary." I am entitled to know whether
16 he views himself as requesting a summary, and then, if he
17 did, I'll ask about it. But I appreciate your effort to
18 narrow any confusion, or eliminate any confusion about my

1 asked for. I can tell you I asked for specific summaries
2 of specific information at various times, but I didn't ask
3 for summaries for all information at all times,
4 Q. (by Mr* Bradley) All right. So you did make
5 a request for summaries of some information from Monsanto's
6 corporate medical department in I960 until the time you
7 retired?
8 A. Yes1 testified to that previously.
9 0. On what topics did you request summaries from
10 Monsanto's corporate medical department between 1980 and
11 the time of your retirement? 12 A. The first summary that 1 asked for was probab
13 ly in the fall of 1980, about that time frame. After I had
14 been in the job a few months, I asked Dr. Gaffey, who was
15 the director of our epidemiology department, to provide me
16 with a summary of all of the known human health effect
17 studies that, had been published.
18 Q. Did you request summaries on any other topics
19 from Monsanto's corporate medical department?
20 A. Yes. In 1981, I asked the director of our
21 toxicology department to provide me with summaries of our
22 chronic animal-feeding studies that had been performed at
23 IBT Laboratories, a summary of the data, and a summary of
24 information related to other animals' feeding studies -
25 PCB's.

3 Q. Yes,
4 A. Those are the two major topics that come to
5 mind.
6 Q. Between i960 and until the time of your
7 retirement did Monsanto's corporate medical department
8 Include the industrial hygiene section?
9 A. Yes, it did.
10 Q. Between 1980 and the time of your retirement 11 did Monsanto's medical department include a toxicology
12 section or department?
13 A, Yes.
14 Q. Who was the head of toxicology within
15 Monsanto *s medical department in 1981?
16 A. I believe it was Dr. George Levinskas,
17 Q. Did Dr. Gaffey provide you with a summary of 18 all of the known human health affect studies that had been
19 published?
20 A. What Dr. Gaffey provided me with was a sum21 mary of the significant literature of human epidemiological
22 studies and some clinical studies which had been published
23 primarily in the Peer Review Journal, and he prepared this
24 in a format suitable for a presentation in a Peer Review

12 any other information from Monsanto * s corporate medical
13 department regarding any and all alleged potential or
14 actual hazards of PCB's or roonochlorinated biphenyls? 15 A. Again, I guess the breadth of the question

19 requests to the corporate medical department for informa-
20 tion on that topic.

5 form in 1980 indicate known toxicologicalinformation
6 regarding PCB1s?
7 A. Yes, they did.
8 MR. BRADLEYi Okay. Would you now go back
9 about three questions. I want to hear the question to
10 which he responded, "In 1980, I published the generic
11 material safety data sheet... 12 (Thereupon, the reporter read back the question and

20 in the Peer Review literature that was 'identified in our
21 search. I would have the head of the particular department
22 that had a particular expertise look at these documents in
23 particular and give me their opinion as to what they 24 thought about the document, what it said, since I'm a lay

3 Q. Anything else?
4 A, No. That's roughly it. That's about as broad
5 as 1 can make it.
6 Q. All right. And did you make those requests to
7 Monsanto1s corporate medical department regarding those 8 Peer Review Journal articles -- were your requests made in
9 writing?
10 A. Sometimes they may have been; sometimes it may
11 have been as casual as a phone call. 12 Q, And were the responses of the corporate
13 medical department to your requests for reviews of journal
14 articles given to you in written form? 15 A. Sometimes they may have been, and sometimes it
16 would be a phone call back, or whatever, 17 Q. In March of 1976, or at any time later, did
18 Monsanto gain knowledge that exposure to PCB*s on one's
19 skin could lead to the PCB's being absorbed into one's *
20 body?
21 A. In what time period?
22 Q, From March of 1976 to today's date. 23 A. We certainly knew that in 1976, yes.

3 answer that question.
4 MR. BAUERi His question was, "acquired."
5 Listen to the question, and you've got to answer the
6 question as it's posed.
7 Q. (by Mr. Bradley) And 1 am going to refer to
8 that time period either as "the date, or "during that
9 period of time," or something similar.
10 During that period of time, did Monsanto know
11 that if PCB's enter the skin, it could cause a condition
12 known as chloracne?
13 A. Under certainconditions, yes.
14 Q, And during that period of time, did Monsanto
15 know that if PCB's entered the body through the skin in
16 sufficient quantities to cause chloracne, that it could be
17 a sign of more systemic poisoning?
18 A. I guess I don't know what you mean by the term
19 "systemic poisoning."
20 Q. Did Monsanto know that during that time that,
21 if PCB's entered the body through the skin and chloracne
22 was formed, that it could be an indication of damage to
23 one's liver, or to --
24 A. Yes.

1 that any of its PCB products contained polychlorinated
2 dibenzofurans?
3 A Did it learn during this time period? We
4 certainly knew during the time period, whether we had
5 learned it during that time period -- I will say yes
6 0 So in March of 1976 Monsanto knew that some of
7 its PCB products contained polychlorinated dibenzofurans,
8 correct?
9 MR. BAUERi Object to the form. I think what
10 he just testified to was that it knew it during the time
11 period -- Monsanto knew that during this time period, but
12 he wasn't sure when it learn it. So I don't know how he
13 could answer the next question, when did it know it in
14 1976, when he has testified he didn't know when it learned
15 it.
16 But go ahead, if you can answer. 17 0. (by Mr. Bradley) As I understand your answer,
18 you don't know the specific date that Monsanto learned that
19 some of its PCB products contained polychlorinated dibenzo20 furans, but it knew that information by at least March of
21 1976; is that correct? 22 A. I believe that is correct 23 Q. During this time period, did Monsanto learn 24 anything about the alleged or potential or actual hazards
2 5 of the polychlorinated dibenzofurans which were part of the

2 MR* BAUERi Objection* Vague as to whether
3 you are talking about knowledge of furans, generally; in
4 any dose, or knowledge in the dosage that they were being
5 found in the Arodors.
6 MR* BRADLEYi Read the question back*
7 (Thereupon, the reporter propounded the previous
8 question.)
9 A. Yes.
10 Q. (by Mr* Bradley) When did it learn that
11 information?
12 A. I don't think that there is a specific date.
13 During that time period they knew that information.
14 0* Did Monsanto -- Do you know whether Monsanto
15 knew that information -- and by "that information," I'm
16 talking about the alleged or real hazard of the poly
17 chlorinated dibenzofurans -- before March of 1976?
18 MR. BAUER: Same objection. Vague as to
19 whether we're talking about any dose versus, for instance,
20 the dose in the Aroclors.
'
21 A. What Monsanto knew was that the testing result
22 of the Aroclor polychlorinated biphenyls gave a certain re
23 sult, whether that result was based on the testing of these
24 materials as manufactured, as they came from the plant, as
25 they were shipped, as they were used. So whatever the re
- 29 -
CONCANNON & JAEGER

1 salt was was the result of the commercial material with
2 whatever it contained, so the test results that were
3 obtained would show no chronic effects, had no chronic
4 effects, or the PCB, ae they had no effects. So what they
5 knew is that the material, ae tested, gave whatever result
6 it gave, and whatever it contained contributed to that or
7 did not contribute to that So that is what they knew.
8 Q. Did Monsanto learn anything during this time o period about any specific health effects associated with
10 polychlorinated dibenzofurans of the type that were found
11 in Monsanto's PCB products?
12 A. I guess I don't know bow to answer that ques
13 tion, either. It's very broad and vague. I'm not sure
14 what you're looking for.
15 Q. Well, I'm less interested in you're knowing
16 what I'm looking for than in your answering my question.
17 But if they go hand in hand, then I can make an effort to
18 make my question better understood. I'm interested in
19 knowing whether, during this time period, Monsanto learned
20 any distinct information regarding the ''health hazards of
21 polychlorinated dibenzofurans of the type that were found
22 in Monsanto's PCB products.
23 A. To my knowledge, there has been no direct 24 testing of PCDP, per se, to determine health effects of
25 animals or humans or anything else, So I would say the

1 answer is no. I don * t know of any direct testing of PCB's
2 at any time.
3 Q. Are you aware of any papers that have dis
4 cussed the relative toxicity of polychlorinated dibenzo-
5 furans, comparing their toxicity to the toxicity, for
6 example, of PCB's?
7 A. Yes.
8 Q. When did Monsanto learn that information?
9 MR. BADERt object to the form, it's beyond
10 the scope in terms of time frame.
11 But you can answer to the extent that you know
12 the answer.
13 A. The relative comparisons of toxicities was
14 first discussed in the scientific literature in about the
15 1982-*83 time frame.
16 Q* (by Mr. Bradley) So is that roughly the
17 period, then, when Monsanto learned the information?
18 A. About the relative toxicities?
19 Q. Yes
20 A. Or -- I'd say it's when Monsanto learned that
21 there were relative comparisons of toxicities being made.
22 This is without testing data This is based on other --
23 Q. So Monsanto learned of the information about
24 the time that the comparisons were made in the published

7 MR, BRADLEYi That's fine.
8 Not pseudoscience, that you referred to in the

4 that over one million pounds of PCB's which were produced
5 by Monsanto between 1929 and 1979 were released to the
6 environment and are still present out in the environment?
7 A. Monsanto is aware that PCB' have been
8 released to the environment I don't know what level of
9 PCB`e or what poundages are in the environment. I don't
10 think we have any data on that; but PCB's have been

11 industry consensus group? 12 A, This was a meeting of the industry consensus
13 group with EPA staff members, convened by Lee Thomas, the
14 administrator of the EPA, and it was prior to the new spill
15 cleanup rule. We were developing the final standards in
16 1987, so this note was probably written within six months
17 of that meeting where we developed the final standards for
18 the regulations.
19 0. 20 of 1987?
So it was probably written within six months ^
21 A. whatever time it took for the rule to go in
22 and come out
23 Q, Did Monsanto learn during the period of time
24 we have been discussing, referring again to March, '76 to
25 July 21, 1993, whether dibenzofurans in Aroclors manu-

1 factured by it were as high as ten parts per million?
2 A. Did we learn from *76 to --
3 Q. Between March of 676 and today's date, that
4 the highest values seen for polychlorinated dibenzofurans
5 in Aroclore manufactured by Monsanto was ten parts per
6 million.
7 A. The highest number that I have seen was the
8 number published in the National Academy of Science Report,
9 and it was less than that. The report said that it was in
10 the order of two, the highest number reported.
11 That was a hypothetical number that Dr.
12 Silvergeid was using. We were calculating to see what a
13 suitable cleanup level would be. And she assumed that --
14 She just picked a number and assumed, if it were as high as
15 that number, it would be inconsequential, because, if PCB'e
16 were fifty parts per million and polychlorinated dibenzo-
17 furans were as high as ten, then the concentration left in
18 the residuals of the leaky electrical piece of apparatus
19 would be less than a half a part per trillion, which was
20 significantly less than the regulatory ^cutoff level, and
21 that it would be toxicologlcally insignificant.
22 0. Do you know whether, by the reference to
23 dibenzofurans in this exhibit, Dr. Silvergeld --
24 A. That's her statement. She said she saw that
25 level. I didn't see that level.

CONCANNON & JAEGER

1 Q. I understand that, but by the term "dibenzo-
2 furans," did you understand that to be chlorinated dibenzo-
3 furans?
4 A. PCDP`8, yes That was what the discussion was
5 about.
6 Q. I am now going to she you what has been marked
7 for identification as Plaintiff's Exhibit 2916 and ask you
8 if you have seen that document before?
9 A. I don't know if I have or not.
10 Q. All right, I am now going to show you Plain-
11 tiff's Exhibit 2915 and ask if you have seen that document
12 before.
13 A. 1 don't think I have seen this document be-

15 Q. I am now going to show you Plaintiff's Exhibit
16 3066 and ask if you have seen that document before.
17 A. I don't think I ever saw this. I wish I had.
18 0 Do you know whether Dr. Throdahl is still
19 living?
20 A. I believe he is still alive. 21 o. Is he retired?

2 Q. Do you recall the name Dr. Louis Fernandez? 3 A, Yes.
4 Q. What position if any did Dr, Fernandez have at
5 Monsanto?
6 A At one point in time he was as high as chair
7 man of Monsanto, .president, CEO, and that may have been
8 about that time frame.
9 Q. On Exhibit 3066 do you see the section that
10 says reference, colon, LF/MCT 12/13/79?
11 A. Yes. 12 Q. Does that mean anything to you?
13 A. It's the initials of the two gentlemen the
14 memo is about, and the date, and I don't know what else it
15 means.
16 Q. Who is the memo about, the two gentlemen?
17 A. Well, the memo is to Dr. Louis Fernandez, L.
18 F., and it's from M,C, Throdahl, and those are the ini
19 tials . 20 Q.
* What was EPS at Monsanto in 1979?
21 A. EPS was the Environmental Policy Staff. That
22 was the beginning of the environmental organization that I
23 mentioned when I became involved. The Environmental Policy
24 Staff was corporate, and they provided the general direc
25 tion of each operating company who had people at lower

6 0 * Yes*
7 A. No. in '79 I was MIC.
8 Q. in '80 were you part of the corporate function
9 Of EPS?
10 A. In June of 1980 I assumed part of the cor
11 porate portion of EPS and assumed the job similar to what 12 is described there.
13 Q. And in -- Were there other corporate members
14 of EPS that included members of Monsanto's board of direc
15 tors?
16 A. The Environmental Policy Staff was primarily a
17 working group that didn't include the board of directors.
18 Mr. Throdahl was the vice-president of environmental
19 affairs, and he was also simultaneously a board member,, /* '
20 an internal board member, an EPS board member. Other
21 members of the EPS were lower-level working staff, if
22 that's clear.
23 Q. When you began your job in June of 1980 with 24 EPS -- First of all, am I correct that you began a job in
25 June of '80 with EPS?

1 A. I guess I might have misspoke I began my job
2 in 1980 as the corporate focal point for PCB, and that
3 remained in the industrial chemical company for a period of
4 time, and at some point in time that moved over to the cor
5 porate staff department, which is EPS# but my initial
6 assignment was to keep up with what was done within the
7 operating company The environmental staff in the operat
8 ing company# as an ad hoc member of the BPS# it was not
9 corporate* It was more or less a bookkeeping type of
10 thing,

1 was told that a better phrase would be PCB's blended by
2 Monsanto. 3
MR. BAUERs Be said dielectric fluids blended,
4 not PCB*b blended.
5 Q. (by Mr. Bradley) Well, whatever he said.
6 Did Monsanto ever, during the period of time
7 that you have been designated as a witness for today's 8 deposition, learn that any form of dioxin, including
9 chlorinated dibenzodioxin, were found in any PCB dielectric
10 fluid blends manufactured by Monsanto?
11 A. As manufactured and sold by Monsanto? Is that
12 what you mean?
13 Q. (by Mr. Bradley) Yes.
14 A. The answer is no. Dioxins have not been found
15 in any PCB'b or PCB blende used as dielectrics sold by
16 Monsanto, to my knowledge. 17 Q. In 1980 when you became the focal point for
18 responding to PCB issues at Monsanto, was there a potential
19 unresolved issue involving contaminated hot spots, example, f^ '
20 at the Hudson River in Waukegan Harbor?'
21 A. Yes.
22 Q. Was there a potential unresolved issueregard
23 ing poly -- possible chlorinated dibenzofurans in aged or

2 question.)
3 MR. BAUERi object to the form. Vague about
4 what a "possible unresolved" --* Vague as to what a poten
5 tial unresolved issue about something possible means.
6 But you can answer if you are able.
7 Q. (by Mr. Bradley) I meant when you became the
8 focal point.
9 A. There was an unresolved issue# yes.
10 Q. What was that potential unresolved issue?
11 A. There was a question as to whether PCDP's were
12 generated during incineration of PCB's in an EPA-approved
13 type incinerator. The question of -- EPA was looking for
14 incinerators with .999999# or bo, so the measurement of
15 this was very -- That is one potential problem.
16 Q. When you began your work as the focal point
17 for PCB's at Monsanto was there a potential unresolved
18 issue regarding reduction of body levels of PCB's by
19 absorbent drugs?
20 A. Yes.
'
21 Q, What was that unresolved issue?
22 A. There had been published literature to the
23 effect that you could treat persons who had high body bur
24 dens of PCB's in their adipose tissue or blood serum with
25 certain compounds which were designated drugs# not necesfln ^ Q

2 remove these PCE'b from the human body
3 Q. When you began your work as the focal point of
4 Monsanto, was there a potential unresolved issue regarding
5 PCB's being possible carcinogens?
6 A fes
7 Q. Was that issue ever resolved for Monsanto?
8 A it's still ongoing
9 Q. Does Monsanto take the position that PCB's are
10 possible carcinogens?
11 A. Monsanto takes the position that PCB's lower
12 than sixty percent chlorination are not carcinogenic in
13 animal studies, and Monsanto takes the position that PCB's,
14 per se, have not been shown to be human carcinogens.
15 Q Does Monsanto take the position that pcb*s
16 with chlorination of sixty percent or greater are possible
17 carcinogens?
18 A. Monsanto takes the position that PCB1s with
19 sixty percent chlorine or greater could be possible car-
fa f 20 cinogens in certain animal species at certain doses,
21 rodents, for example.
22 Q. But not in humans
23 A. Correct. Not in humans.

COMPUTER AIDED TRANSCRIPTION
1 A. NO.
2 Q. In 1980 when you were the focal point for
3 Monsanto on issues involving PCB's, was there a potential
4 unresolved issue of PCB'e in the food chain including
5 mothers* milk?
6 A Yes.
7 Q. What was thatpotential unresolved issue?
8 A. The potential unresolved issue was, is there
9 sufficient PCB in the food change to provide a dose level
10 sufficient that it will cause human health effects.
11
Q.
And does Monsantotake theposition that
there
12 is a level of PCB's in the food chain including mothers'
13 milk which would cause adverse health effects?
14 MR. BAUERi Object to the form. What do you
15 mean, "would?"
16 Q. (by Mr. Bradley) Let me rephrase it, then.
17 Does Monsanto take the position that there is a dose level
18 of PCB's in the food chain including mothers' milk which
19 results in adverse human health effects?
20 MR. BAUERi I still object to the form. I
21 understand dose level*, I understand food chain, but you put
22 the two together and 1 think the question is vague.
23 But you can answer
24 Q. (by Mr. Bradley) I'll try one more time.
25 Does Monsanto take the position that there is any level of
CONCANNON & JAEGER
WATER PCB-00050044
COMPUTER AIDED TRANSCRIPTION
1 PCB's in the food chain including human mothers' milk, which
2 could cause adverse health effects? 3 A, Monsanto takes the position that the dose
4 level is critical in determining human health effects, not
5 absolute concentration So you would have to know the
6 dose, which is the consumption per unit of tine per kilo
7 gram of human body weight. 8 0, is there a dose level in which PCB's in the
9 food chain including human mothers' milk could cause
10 adverse human health effects?
11 MR. BAUER r Object to the form of the ques 12 tion. He just explained -- Are you asking whether we know
13 that there is a dose level in some particular species?
14 That if someone -- 1 mean# a concentration, 1 think, is the
15 problem. Never mind. I am not going to argue. Asked and
16 answered. Object to the form, and asked and answered. 17 You can answer the question.
18 A. I am not sure I can answer the question. I
19 guess I'm not sure what the question is now.
20 Monsanto has not taken the position that we
21 know that there is a level of PCB's that causes an adverse
22 human health affect.
23 Q, (by Mr * Bradley) in 1980 when you became the
2 4 focal point for Monsanto's PCB questions and problems and
