7 THE WITNESS: I do.
8 DIRECT (Eric Flaig)
9 BY MR. BLANK:
10 Q. For the record, sir, would you state your
11 name and address?
12 A. My name is Eric George Flaig. I live at
13 131 Eider Court, Royal Palm Beach, Florida.
14 Q. My name is Robert Blank. I am an attorney
15 for U.S. Sugar Corporation, the Florida Sugar Cane
16 League, and New Hope South and am taking your
17 deposition in the context of the SWIM plan
18 administrative challenge. If I ask you any questions
19 that you don't understand, would you please indicate
20 that to me, and I'll attempt to rephrase the
21 question.
22 A. Yes, sir.
23 Q. Okay. Where are you presently employed?
24 A. South Florida Water Management District.
25 Q. And what is your position with the
5
1 District?
2 A. I'm a senior civil engineer.
3 Q. Are you assigned to a particular
4 department?
5 A. I am in the Kissimmee and Okeechobee
6 Systems Research Division of the Research Department.
7 Q. And when you say Kissimmee and Okeechobee,
8 what geographic area does that include?
9 A. That geographic area includes the upper
10 east coast, the lower west coast, Kissimmee River
11 Valley and Lake Okeechobee.
12 Q. Does it include regions south of Lake
13 Okeechobee?
14 A. It does not include the EPA or the EAA or
15 those areas south of that. I believe it includes
16 some parts of the lower east coast, which are,
17 latitudewise, south of Okeechobee.
18 Q. I show you a document which we will mark as
19 Flaig Number 1.
20 (The document was marked
21 Flaig Exb. No. 1.)
22 BY MR. BLANK:
23 Q. Can you identify that document, sir?
24 A. That is my Curriculum Vitae.
25 Q. Is this the most recent Curriculum Vitae
6
1 that you have?
2 A. Yes, sir.
3 Q. Under the first item on that document
4 marked 1992, which I would assume means 1992 to
5 present; is that correct?
6 A. Yes.
7 Q. That's a reflection of your current
8 position with the District?
9 A. Yes.
10 Q. The first item there, Developed GIS data
11 base for dairy region --
12 A. Yes.
13 Q. -- can you tell me what you did in that
14 regard?
15 A. That is converting the design plans and the
16 site plans for the dairies and adjacent lands into a
17 digital data base to be used for analysis and
18 interpretation of water quality and data.
19 Q. What is a GIS data base?
20 A. GIS is Geographic Information System. A
21 way to relate spacial data with tabular information
22 for analysis and interpretation.
23 Q. And is that work complete?
24 A. At this time it is ongoing.
25 Q. When do you anticipate it will be complete?
7
1 A. The major components of it should be
2 complete by June. The remainder we would hope would
3 be complete by mid '94. However, with any geographic
4 information system, it is continually updated and
5 improved.
6 Q. And the next line item there, provide
7 direction for activities of several research and
8 planning contracts, does that item also refer to
9 matters involving the Lake Okeechobee and Kissimmee
10 basins?
11 A. Yes, sir.
12 Q. And what type of research and planning
13 contracts were you involved in?
14 A. Fate and transport of phosphorus and
15 regional analysis of best management practices.
16 Q. What sources of phosphorus were you
17 concerned with in that regard?
18 A. We are concerned with all imports of
19 phosphorus into the Okeechobee basin and particularly
20 those sources used for animal feed and fertilizer.
21 Q. This did not relate to sources of
22 phosphorus relating to sugar cane, farming or farming
23 south of Lake Okeechobee?
24 A. Not at this stage.
25 Q. What about sources of phosphorous with
8
1 regard to mineralization or oxidation of soils? Was
2 that involved in this project?
3 A. There was some work done in these projects
4 on mineralization.
5 Q. Can you describe that work?
6 A. Yes.
7 Q. Would you do so?
8 A. Yes. Ramesh Reddy of the University of
9 Florida is on contract with us to look at rates of
10 phosphorus absorption and participation, and as
11 necessary, ambient levels of mineralization firm
12 organic matter in streams and wetlands in the
13 Okeechobee basin. As such, he's looking at
14 mineralization; however, he is not looking at
15 mineralization of organic soils per se, as would be
16 found in the EAA under the contracts that I manage.
17 I believe he is doing so under other contracts that I
18 am not familiar with.
19 MR. COUSINS: Can I just interrupt one
20 second off the record?
21 (Discussion held off the record.)
22 BY MR. BLANK:
23 Q. You said that Dr. Ramesh Reddy was involved
24 in other contracts relating to mineralization of muck
25 soil similar to ones found in the EAA; is that
9
1 correct?
2 A. I believe so.
3 Q. Do you know who would be administering
4 those contracts?
5 A. I'm not sure.
6 Q. It would be somebody with the District,
7 though, that would be supervising that work?
8 A. Yes, sir.
9 Q. Who is your immediate supervisor? Let me
10 rephrase. Maybe you can just explain briefly the
11 hierarchy of your department. Who do you report to
12 and who reports to you?
13 A. Briefly, huh? Depending on the assignment,
14 I report to either engineering supervisor Dr. Todd
15 Tisdale, division director Nick Ammon, or department
16 director Tony Federico.
17 Q. Who reports to you?
18 A. Nobody.
19 Q. Do you have any other staff that work with
20 you on various projects that you're involved in?
21 A. Depending on the assignment and the nature
22 of the data I require to complete the work, I
23 interact with many people in many departments.
24 Q. Have you interacted with anybody, any
25 people involved with projects located in the EAA?
10
1 A. Currently I make every effort not to be
2 involved in Everglades issues.
3 Q. Have you been successful in that effort?
4 A. Not by my presence here today. For those
5 who may read this later, my activities in the basins
6 north of the lake are a full-time job plus.
7 Q. What have been your activities in the EAA?
8 What projects have you been involved in in the EAA?
9 A. From what point in time?
10 Q. From the start of your employment with the
11 District to date.
12 A. Okay. From approximately the time I was
13 employed with the District, I was assigned the
14 responsibility for managing what we refer to as the
15 EAA BMP contract with Forest Izuno and Del Botcher of
16 the University of Florida. I worked on that project
17 for approximately five years, ending one year short
18 of completion of that work effort. I worked on the
19 first draft of the Everglades SWIM Plan, which was
20 completed in 1989. Pursuant to that, I worked on
21 developing literature review on soil phosphorus
22 behavior and phosphorus budgets for the EAA.
23 As part of the EAA BMP contract I, worked
24 with the University of Florida on delineating
25 information relative to best management practices.
11
1 All of my work in the Everglades region has been
2 limited to the EAA.
3 Q. The last item you mentioned, work with the
4 University of Florida on a BMP contract -- did I get
5 that correctly?
6 A. Yes, sir.
7 Q. How does that differ from the first item
8 you mentioned, which was the EAA BMP analysis?
9 A. Only in the sense that there were two
10 things I did: One was the EAA BMP contract, and the
11 other was back-up information for the SWIM plan. And
12 under the heading of back-up information for the SWIM
13 plan, there were three activities; soil phosphorus,
14 phosphorus budgets, and best management practices.
15 So that is a subtitle underneath that. One is review
16 of BMPs and the other is contract management. And in
17 review of data sets.
18 Q. All right. I missed the third item you
19 mentioned. Soil phosphorus, phosphorus budget and --
20 A. Best management practices. BMPs.
21 So I believe your question is how does 1
22 differ from 2C, as it were?
23 Q. Yes.
24 A. 1 is contract management and review of data
25 sets, and 2C was review of BMPs as best available
12
1 information. And that all pertains only to the 1989
2 draft of the Everglades SWIM Plan.
3 Q. What was your involvement in the current
4 Everglades SWIM Plan, the 1992 SWIM plan?
5 A. I have had no direct involvement and I do
6 not know how much of materials I developed previously
7 were used. I have not read the '92 SWIM plan.
8 Q. Were you involved in the formulation of the
9 District BMP rule?
10 A. I believe I was.
11 Q. What was your involvement in that?
12 A. Beginning in June of 1991, I participated
13 in discussions with the Federal Government and the
14 District in defining what components ought to be
15 included in the -- what do we call it -- the BMP
16 rule.
17 Q. That's what I call it, yes.
18 A. Okay. I think it would work for the
19 District. The Everglades Rule. I'm not sure. Okay.
20 Either way.
21 My discussions at that point continued for
22 a couple of months with various individuals in
23 defining what kind of components ought to be in the
24 rule, what kind of policy instruments, and my
25 participation ended somewhere around October of '91.
13
1 However, the rule was completely adopted considerably
2 later, and I am not sure how much of the
3 communications I was involved in were directly used
4 in the rule, as opposed to developed from other
5 sources or modified after my discussions with the
6 feds.
7 Q. You said in discussions with the feds. Can
8 you identify who was involved in those discussions?
9 A. Yes.
10 Q. Who?
11 A. Myself, Dick Rogers, John Burt and Dan
12 Scheidt.
13 Q. Who is John Burt?
14 A. John Burt is a program administrator with
15 SCS USDA.
16 Q. And who is Dick Rogers?
17 A. Dick Rogers at the time was director of the
18 Planning Department.
19 Q. Of?
20 A. South Florida Water Management District.
21 Q. Is he still there?
22 A. He is still at the District.
23 Q. Why were discussions held with federal
24 employees concerning the components of the BMP rule?
25 A. I don't know.
14
1 Q. Who arranged for these discussions?
2 A. I don't know.
3 Q. What concerns were expressed by either Mr.
4 Burt or Mr. Scheidt concerning the necessary
5 components of the BMP rule?
6 MR. COUSINS: Object to the form.
7 Go ahead and answer it.
8 I guess when you say what concerns were
9 expressed, there is no record that any concerns
10 were necessarily expressed.
11 BY MR. BLANK:
12 Q. You understand the question?
13 A. I believe I do. I do not recall specific
14 concerns in the sense of a list of this, this, this
15 and this. The general concerns, of course, from Dan
16 Scheidt, who represented the Park, were protection of
17 the downstream system and long-term protection. The
18 concern of John Burt, in general, was, of course,
19 protection of the downstream environment, but also
20 protection of agricultural production systems in the
21 EAA. He did not wish to see a rule adopted that
22 would unnecessarily limit ag production.
23 Q. Did Mr. Scheidt share that concern, to your
24 knowledge?
25 A. I do not remember him expressing such a
15
1 concern.
2 Q. Did these discussions that you had result
3 in a definition or a delineation of the components to
4 be included in the BMP rule?
5 A. At that time we completed the meeting with
6 a list of policy instruments that ought to be
7 considered in the development of a successful rule.
8 Q. Can you tell me what those were?
9 MR. COUSINS: Can I just state, to the end
10 we are getting involved in any kind of
11 settlement negotiations or discussion, just a
12 general objection as to the relevancy of this
13 presently in this particular action. I am not
14 going to stop you from asking questions, but I
15 just want to make that note on the record.
16 MR. BLANK: All right. I would also like
17 to note for the record I don't think we are
18 talking about settlement discussions at this
19 point in time.
20 BY MR. BLANK:
21 Q. You can correct me if I am wrong, but these
22 discussions were not part of a general settlement
23 discussions with regard to the federal lawsuit, were
24 they?
25 A. I believe that was the intent of the
16
1 discussions.
2 Q. Oh, okay.
3 MR. ROSENBERG: I concur in the objection.
4 BY MR. BLANK:
5 Q. What components did you arrive at?
6 A. As I said, we came up with a list of
7 components that ought to be considered in the
8 development of a rule. What in the end was included
9 in the rule involves further discussions much later,
10 of which I was only partially involved.
11 The component that we discussed there --
12 and I don't remember all of the components, and I
13 have not had time to review the documents completely --
14 is we wanted to make sure there was education and
15 training of both ag managers and field staff, we
16 wanted monitoring of BMP implementation, on-site
17 water quality monitoring of some reliability, and, of
18 course, basin spill monitoring, essential for
19 determining inflows into the EPA. There should be
20 some form of staged incentives for quick development
21 of BMP technology. There should be some staged
22 penalties for significantly penalizing those who
23 would not participate to the best of their ability,
24 in development and implementation of a BMP program.
25 Q. These various components were directed at
17
1 reducing phosphorus loads from the EAA; is that
2 correct?
3 A. Yes, sir.
4 Q. Did you establish any goal with regard to
5 the amount of reduction that could be achieved by
6 implementing these components?
7 A. I don't remember that. There was
8 considerable mixed feelings as to how much phosphorus
9 load reduction could be achieved by BMPs, and the
10 numbers that various people considered had
11 considerable disagreement on what the load reductions
12 could be, so I don't believe we focused on what
13 phosphorus load or concentration reduction goals
14 ought to be considered in the rule.
15 Q. And you did not participate in drafting of
16 the final rule; is that correct?
17 A. I participated in some of the early drafts,
18 but I was not involved in the final drafts.
19 Q. Did any of the drafts that you participated
20 in have a phosphorus reduction goal?
21 A. I don't recall. My intent was to make sure
22 that a broad spectrum -- there were broad spectrums
23 of policies that would help encourage the
24 implementation of practices to reduce phosphorus
25 loads. I was not particularly concerned with the
18
1 target goals that the District or anyone else wanted
2 to see developed in the rule because that involved
3 targets set for EPA, targets set for the STAs, of
4 which I was not knowledgeable. So I could not
5 discuss the question of what load reductions were
6 necessary or required.
7 Q. When you say targets set for EPA, are you
8 referring to the Everglades Protection Area --
9 A. Yes, sir.
10 Q. -- when you say EPA?
11 A. Yes.
12 Q. Did you analyze the various components that
13 you have just described to determine what type of
14 reduction in phosphorus load would be achievable if
15 these components were implemented?
16 A. No.
17 Q. Did you ever reach any opinion concerning
18 the amount of phosphorus reduction that would be
19 possible if these components were implemented?
20 A. Yes.
21 Q. What was that?
22 A. I believe if all components of the rule
23 were developed to completion, we should see 60, 70
24 percent reduction in load, and I have stated that in
25 public forum to our Board.
19
1 Q. Can you give me a breakout of the various
2 components that would lead to that type of a
3 reduction?
4 A. Could you restate that?
5 Q. Yeah. What components of BMP, best
6 management practices, if implemented, would result in
7 that type of a reduction?
8 A. Can you re-read the question?
9 (Thereupon, a portion of the record
10 was read by the reporter.)
11 THE WITNESS: The components of BMPs and
12 how much load reduction they would achieve is,
13 of course, separate from implementation of these
14 various other policies, because BMP
15 implementation is only one of the policies that
16 were being considered at the time. Of the BMPs
17 that you could recommend for the Everglades
18 Agricultural Area, there are several BMPs that
19 have been recommended, which, depending on the
20 site and the soil and the crop type, could
21 achieve phosphorus load reductions. Primary
22 among these are more careful fertilization.
23 BY MR. BLANK:
24 Q. Let's take these one at a time because I
25 want to get into some detail with them.
20
1 When you say more careful fertilization,
2 can you describe that a little more specifically?
3 A. That's where I was going with it. Within
4 fertilization, first would be soil testing to
5 determine the appropriate fertilization rates that
6 are specific to the field that is being fertilized.
7 That's one component.
8 A second component is where --
9 Q. Hold on that just a minute. When you say
10 soil testing to determine the appropriate
11 fertilization rates --
12 A. Right.
13 Q. -- how would the soil testing tell you what
14 fertilization rates to utilize?
15 A. Soil testing would tell us about the
16 availability of the phosphorus already in the soil
17 and how much we expected was available for crop
18 uptake and for sufficient yield from that field to
19 meet production goals.
20 Q. Is phosphorus the only element that we are
21 concerned with when we talk about fertilization?
22 A. No.
23 Q. What other aspect, what other chemical
24 components of fertilizer, are we concerned with here?
25 A. All of them.
21
1 Q. Which are?
2 A. Depending on the crop and the soil, other
3 macro micronutrients and trace metals.
4 Q. Can you describe those?
5 A. Not in detail. Overall, nitrogen,
6 potassium phosphorus, your macronutrients, other
7 components of fertilization. They are concerned with
8 boron, copper, zinc, calcium silica, manganese in
9 some locations. I don't recall the full list from
10 there.
11 Q. Would there be any other components of
12 fertilizer other than phosphorus that would create a
13 concern to downstream ecosystems?
14 A. Yes.
15 Q. Which would those be?
16 A. I'm not really in a position to give you a
17 comprehensive list. The list goes in a couple
18 different directions. First of all, those components
19 of a standard fertilizer that affect phosphorus
20 uptake will affect the phosphorus loss and in
21 loadings downstream, and that's the most obvious.
22 I think your real question is, do the other
23 metals in the fertilizer affect downstream metal
24 loads to EPA? I'm not an expert in that area, so I
25 can't answer that.
22
1 Q. Do you know of anyone that has expressed a
2 concern with regard to those other metals and their
3 effect downstream?
4 A. I don't know of anybody who has expressed a
5 concern other than the general concern over mercury,
6 and I know of no analysis that has been done relative
7 to fertilizer imports on mercury fate.
8 MR. BLANK: Could you read back the last
9 part of his answer?
10 (Thereupon, a portion of the record
11 was read by the reporter.)
12 BY MR. BLANK:
13 Q. Is mercury normally a component of
14 fertilizer used in the EAA?
15 A. I would believe, as with most fertilizers,
16 it is at least a trace contaminant. On the more
17 obvious layman interpretation, I doubt that they
18 include mercury for fertilization.
19 Q. Why do you feel it would be a trace
20 contaminant in fertilizer?
21 A. Because most fertilizer materials come from
22 impure processing of mineral materials, of which it
23 is nearly impossible to remove trace metals; so
24 consequently, from the rock phosphate and other
25 materials going into it, there will be a trace of
23
1 other associated elements that it is not economical
2 to remove from the material.
3 Q. Are you aware of any studies that have
4 analyzed fertilizer used in the EAA to determine
5 mercury contents?
6 A. I'm not aware of any.
7 Q. All right. That was the first item you
8 mentioned; more careful fertilization as a BMP
9 practice.
10 A. That was part of that answer.
11 Q. Was there more to the answer?
12 A. Yes.
13 Q. What is that?
14 A. Briefly, application methodology and
15 handling of materials.
16 Q. What do you mean by application
17 methodology?
18 A. One instance of that would be band
19 fertilization of row crops versus -- particularly
20 vegetables -- versus broadcast application. And
21 other techniques may include, depending on crop and
22 soil type, immediate incorporation versus surface
23 application, liquid application versus solid
24 materials.
25 Q. Is this a BMP practice related primarily to
24
1 vegetable production?
2 A. The primary application would be
3 vegetables. It is possible that these techniques
4 could also be adapted for sugar cane. At what
5 expense, I'm not sure.
6 Q. All right. Are there any other components
7 to the category of more careful fertilization?
8 A. None that I can think of at this moment.
9 Q. When you say handling methodology, are you
10 referring there to prevention of spills?
11 A. Right. And wastage of materials and clean-
12 up of handling equipment, containment of spills.
13 Q. Do you have any opinion with regard to the
14 percentage of phosphorus reduction that may be
15 achievable by soil testing and the application of
16 fertilizer based on that testing?
17 MR. COUSINS: Are you asking him the
18 percentage of the 60 percent or --
19 MR. BLANK: Yes.
20 MR. COUSINS: Do you understand the
21 question?
22 THE WITNESS: Yes. It can range between 5
23 and 25 percent, depending on soil crop
24 combinations as well as what we believe is going
25 on regionally in the EAA.
25
1 BY MR. BLANK:
2 Q. What do you mean by what you believe is
3 going on regionally in the EAA?
4 A. Well, from a small sampling of observations
5 of handling of materials and the kinds of practices
6 we believe the growers are using, it is possible we
7 could get upwards of 15 percent reduction from these
8 BMPs. However, if we find that our observations
9 represent the poorest handling techniques, then the
10 reductions may only be as much as 5 percent.
11 Q. Well, the first category that we have kinds
12 of labeled soil testing would seem to be directed at
13 the prevention of overfertilization; is that correct?
14 A. Overfertilization plus spills and handling
15 errors associated with that additional unnecessary
16 phosphorus.
17 Q. Well, I have that under my category of
18 application methodology as distinguished from soil
19 testing --
20 A. Right.
21 Q. -- and what I was trying to get at you is
22 an opinion with regard to percentage of reduction via
23 soil testing and then via application methodology.
24 And you gave me a figure of five to 25 percent. Did
25 that encompass both categories?
26
1 A. I really don't feel comfortable giving a
2 percentage of reduction for each of the three
3 subcategories under fertilization methods.
4 Q. Are you aware of any testing that has been
5 done or research that has been done with regard to
6 these three categories and the possible phosphorus
7 reductions that could be achieved?
8 A. I believe the University of Florida
9 experiment station at Belle Glade has been looking at
10 the ramifications of each of these techniques. How
11 far they have gone in the analysis and
12 interpretation, I'm not sure.
13 Q. This work that you referred to by the
14 University of Florida at Belle Glade, was that work a
15 part of the EAA BMP contract that you administered
16 for five years?
17 A. Only one part of it was. And that was
18 considering comparing banding versus broadcasting of
19 fertilizer on cabbage.
20 Q. What individuals were responsible for that
21 research work from the University of Florida?
22 A. Del Botcher and Forest Izuno.
23 Q. All right. Is there anything else under
24 the general category of fertilization practices that
25 would result in a more -- let me restate the
27
1 question. Are there any other categories under the
2 more fertilization discussion that we have been
3 having that would be part of the BMP program?
4 A. I believe, in a general sense, that covers
5 it.
6 Q. All right. What other aspect of BMP
7 program were you concerned with?
8 A. Pump rate reductions.
9 Q. And what is involved in that category?
10 A. Reducing off site pumpage from the farms
11 into the primary canal system in response to
12 potential flooding. The intent was to come up with a
13 new point system for determining when the growers
14 pump to reduce pumping poor water quality into our
15 system.
16 Q. When you say "our" system, what do you
17 mean?
18 A. The District -- well, it is not the
19 District. The Corps of Engineers, I guess.
20 Q. Is this the same thing as not overdraining
21 and keeping the water table at an optimum level?
22 A. That's one component of the pumping. In a
23 sense, I guess that could be developed into a
24 separate category. That would then result in this --
25 the whole category would be improved water
28
1 management, of which there would be three categories.
2 One would be reduce off-site pumping, another --
3 Q. What do you mean by off-site pumping?
4 A. Well, that's what we were discussing about
5 pump rates. Pumping from the farm off site into the
6 primary canal system.
7 Q. As contrasted to pumping within the farm
8 system itself?
9 A. Right.
10 A second component of water management
11 would be improved on-farm pumping of water from
12 sensitive crops to areas not as drastically affected.
13 And then the third area would be water
14 table management/irrigation. And that could also
15 include, in a general sense, water conservation.
16 Q. What would be involved in determining an
17 opinion at the water table that would trigger pumping
18 off site?
19 A. I'm sorry; could you repeat the question?
20 Q. Yeah. You had previously indicated that
21 one of the goals here was to determine a point at
22 which -- or some method for the farmers to determine
23 when to pump and when not to pump --
24 A. Right.
25 Q. -- which, I assume, means the level of the
29
1 water table; is that a correct assumption?
2 A. That's a partially correct assumption?
3 Q. What else would be involved other than a
4 water table level?
5 A. Anticipated rainfall.
6 Q. That, in turn, would relate to the existing
7 water table, though, wouldn't it?
8 A. No.
9 Q. Why not?
10 A. If you were in the wet season and you get a
11 heavy rain at a given water table, you're much more
12 concerned with consequences of another significant
13 rain occurring on subsequent days; whereas if you're
14 in the dry season and you receive -- at a given water
15 table -- and you anticipate a given rainfall, you may
16 not have the expectation of additional severe weather
17 in the accompanying following days, and consequently
18 your concerns about off-site pumping are lower.
19 Depending on the season and the crop, you may or may
20 not be concerned about pumping at all.
21 Obviously, if the land is fallow, you
22 couldn't care, as long as it does not endanger your
23 equipment or your facilities. On the other hand, of
24 course, if you're in the middle of a very sensitive
25 cropping season, where you're in the water table, the
30
1 amount of rain you expect will significantly impact
2 your decision when you need to pump. So it is not
3 single factor. Soil type, crop type, season, water
4 level, as well as your drainage capacity on site all
5 affect off-site pumpage.
6 If one wants to go further, you're also
7 concerned about what your neighbors are doing,
8 because if everybody pumps at once, there is no
9 capacity in the system, and the water is going to end
10 up flowing back onto your property.
11 Q. Is seepage a concern here with regard to
12 pumping from your neighbors?
13 A. I don't know at what degree it is a
14 concern. I mean, if you're doing a mass balance on
15 water movement, it has to be considered in the
16 equation. How significant it is, I am not sure. And
17 again, it depends on where your property is in the
18 EAA, soil type, rock type and canal structuring.
19 Q. Has anyone, to your knowledge, developed a
20 set of guidelines that would be useful for farmers
21 within the EAA to determine when to pump and when not
22 to pump?
23 A. Yes.
24 Q. Who has done that?
25 A. The EAAEPD.
31
1 Q. What is the EAAEPD?
2 A. The Everglades Agricultural Area
3 Environmental Protection District.
4 Q. EPD?
5 A. EPD. Sorry.
6 Q. Okay. Have you reviewed those guidelines?
7 A. Yes.
8 Q. Did you agree with them?
9 A. I found at the time there was insufficient
10 information to agree or disagree with them.
11 Q. When was your review conducted?
12 A. In 1990 and '91.
13 Q. Do you know if anyone else has conducted a
14 review of those guidelines?
15 A. I believe several people have looked at
16 those guidelines.
17 Q. Who else has looked at them? I am
18 concerned here with the District or consultants
19 employed by the District.
20 A. Oh, in a broader sense?
21 Q. Yeah.
22 A. There were several individuals involved in
23 our review of those guidelines, and I believe that
24 they have been reviewed subsequent to our review as
25 applicable to the entire EAA, but I was not involved
32
1 in that activity, so I'm not sure who looked at them
2 then. As for specific individuals, I can't remember
3 names right now.
4 Q. Do you know if the District retained a
5 consultant to review these guidelines?
6 A. At the time I reviewed them, no, we had
7 not. Subsequent to that, I believe they have, but
8 I'm not sure who.
9 Q. Can you give me a range of phosphorus
10 reduction that might be achievable by pump practices,
11 pump rate reductions?
12 A. Yes.
13 Q. What do you think that range would be?
14 A. 10 to 40 percent.
15 Q. Does that range vary with crop type?
16 A. Yes.
17 Q. What type of crops do you think would
18 achieve the most reduction in phosphorus loading by
19 improved water management?
20 A. Sugar cane.
21 Q. Why is that?
22 A. Largest acreage involved.
23 Q. Can the sugar cane farms retain more water
24 without the possibility of crop damage than perhaps
25 other farming types?
33
1 MR. COUSINS: I object to the form of that
2 question. When you say other farming types, are
3 you talking about other crops?
4 MR. BLANK: Other types of crops, yes.
5 THE WITNESS: In general, yes. However,
6 when one reviews the pumpage rate BMP, it is not
7 simply a question of crop type, it is also
8 involves soils, cropping sequences, adjacent
9 fields, internal canal structure.
10 BY MR. BLANK:
11 Q. So could you explain each of those items a
12 little bit more specifically? How does it involve
13 soils?
14 A. Only in general terms, because the answer
15 becomes site specific, and since the analysis of site
16 specific information has not been done, to my
17 knowledge, to make general statements about which
18 crop would be more affected or where this pump BMP
19 would result in greatest load reductions, conclusions
20 cannot be drawn, or I cannot draw conclusions on that
21 at this time.
22 Soil type matters in terms of how deep the
23 soil is and what its water holding capacity is, so
24 that gives you information on how much storage
25 capacity there is on a given farm, and how much
34
1 flexibility the grower has in terms of how much he
2 can vary the water table. Obviously, crops grown on
3 very shallow or very thin organic matter are not
4 going to have the holding capacities or flexibilities
5 of management that those grown in a deep muck soil
6 will have.
7 Q. What types of different soil depths are we
8 dealing with in the EAA? What is the range of soil
9 depth?
10 A. I believe the range is from almost no muck
11 to four meters.
12 Q. What areas would have almost no muck?
13 A. The south end of the EAA.
14 Q. And what type of crops are grown in this
15 area?
16 A. I'm not sure what the current distribution
17 is. Historically, I believe there is a lot of
18 pasture and cane in the south end.
19 Q. And generally, as you get closer to the
20 lake, your muck depth increases?
21 A. Yes, sir.
22 Q. Is that correct?
23 You also mentioned that cropping was a
24 factor in terms of the ability to implement better
25 pumping practices.
35
1 A. Correct.
2 Q. Could you explain that a little bit?
3 A. In general, many vegetables are extremely
4 sensitive to variations in water table depth. Cane
5 crops generally are less sensitive in terms of yield,
6 but it depends also on what period in the -- what
7 stage of the crop growth the crop is in, and that
8 varies across the EAA, depending on planting time and
9 ratoon. And of course, at the farthest extreme, if
10 you're doing aquatic cropping, either aquatic crops
11 specifically, or rice, they are much less sensitive
12 to changes in the water table, particularly on the
13 getting wetter side, and that, in turn, of course,
14 affects the distribution of crops the farmer is
15 likely to select from; and that, in turn, affects the
16 markets that are being exploited.
17 Q. All right. Within this broad category of
18 improved water management, would you include within
19 that category retention of on-farm drainage?
20 A. Yes, sir.
21 Q. Could you explain a little bit what that
22 practice would involve?
23 A. It depends on how it is implemented, but
24 generally it means having a canal structure internal
25 pumping capacity to move water from sensitive crops --
36
1 which are likely to be vegetables, where you're
2 highly fertilizing -- to other areas of your farm
3 property with either less sensitive crops or fallow
4 areas, and hold the poor water quality on site. Poor
5 quality water on site.
6 Q. This practice would involve moving water
7 continuously from field to field within the farm,
8 would it not?
9 A. It depends.
10 Q. That would be one aspect of retaining
11 drainage. That would be one mechanism to retain
12 on-farm drainage.
13 A. I object to the "continuous". There will
14 be periods where you have to move the water on farm,
15 but I don't see it as a continuous process.
16 Q. Periodic?
17 A. Periodic. Thank you.
18 Q. Now, would these improved water management
19 techniques result in a reduced volume of water being
20 discharged from farms in the EAA?
21 A. Yes.
22 Q. Do you have any opinion with regard to the
23 amount of flow that would be reduced by implementing
24 improved water management techniques?
25 A. Yes.
37
1 Q. What is that?
2 A. It could be large or small, depending on
3 how implemented and what operation it was implemented
4 on.
5 Q. What type of range would we be talking
6 about?
7 A. I don't remember enough of the details.
8 Q. Are you aware of anyone that has done an
9 analysis on anticipated flow reductions by
10 implementation of BMPs?
11 A. I believe the EPD produced information in
12 their first report on the amount of flow reductions
13 that would occur to achieve the load reduction is
14 they were looking at, and I do not remember the
15 details.
16 Q. Do you know if anyone at the District has
17 calculated the amount of flow reduction likely to
18 result from BMPs?
19 A. I am unaware of any analysis.
20 MR. COUSINS: Just note for the record;
21 Mr. Flaig has been designated to testify on
22 phosphorus budget, and to the extent that any of
23 these questions that are being asked are
24 relating to that, that's fine, but I think it is
25 a little difficult for him to answer questions
38
1 at the realm of his designation because that's
2 all he's really prepared for.
3 BY MR. BLANK:
4 Q. As part of your BMP analysis, did you
5 consider utilization of on-farm retention ponds as a
6 BMP practice?
7 A. It was introduced as one method of
8 achieving the water conservation, but I have not
9 participated in any analysis of the impact of
10 implementing that practice.
11 Q. What about retention of vegetable field
12 drainage water and sugar cane or fallow lands? Was
13 that a BMP considered?
14 A. It was considered. No specific analysis
15 was done.
16 A. Again, much of the analysis there would be
17 site specific.
18 Q. Were there any other BMP practices that you
19 considered that we haven't discussed?
20 A. I don't recall any.
21 Q. We kind of got off base from your
22 Curriculum Vitae. I might go back to that a minute
23 and keep in some sequence here.
24 The next item under 1990 to '91, senior
25 civil engineer, do you see that item?
39
1 A. Yes, sir.
2 Q. Did this work involve the preparation of
3 the lake SWIM plan?
4 A. No.
5 Q. What was involved there?
6 A. Working on preparation of the update to the
7 SWIM plan.
8 Q. Again we are talking about the lake?
9 A. Lake Okeechobee Interim SWIM Plan.
10 Q. And who were the complex research contracts
11 with, mentioned under that item?
12 A. Well, one of them was this EAA BMP
13 contract, a second one was the soil phosphorus
14 contract for the areas north of the lake.
15 Q. Any others?
16 A. The Class I and III analysis for
17 tributaries draining to Lake Okeechobee, development
18 of the Lake Okeechobee Agricultural Decision Support
19 System.
20 Q. I'm sorry. You said Lake Okeechobee
21 Agricultural Support?
22 A. Decision Support System.
23 Q. What was that?
24 A. A GIS regional planning tool.
25 Q. And attended for what purpose?
40
1 A. Evaluate the impact of alternative
2 phosphorus management strategies for the basins
3 draining into Lake Okeechobee. In laymen's terms,
4 what would be the impact of implementing a specific
5 set of BMPs for given land uses or given basins or
6 other kinds of incentives for reductions of
7 phosphorus loads to the lake? Give the managers a
8 big picture view of the implementation strategies.
9 Q. When you say impact, what type of impact
10 are you referring to?
11 A. Phosphorus loads and economics.
12 Q. To your knowledge, has a similar system
13 been constructed for the BMP practices in the EAA?
14 A. No.
15 Q. Why not?
16 A. I don't know.
17 Q. The next item on your resume' under the
18 category '89 to '90, do you see that item?
19 A. Yes, sir.
20 Q. The last -- well, actually three sentences
21 of that item, first one, negotiated and managed
22 complex research contracts, are we referring to the
23 same contracts you have previously mentioned?
24 A. Yes.
25 Q. And the next item, performed water quality
41
1 data interpretation --
2 A. Yes?
3 Q. -- what did that involve?
4 A. Evaluating tributary water quality draining
5 to Lake Okeechobee.
6 Q. What water quality parameters were you
7 looking at?
8 A. Primarily phosphorus, but also nitrogen.
9 Q. And what type of interpretation did you
10 make of the data?
11 A. Statistical.
12 Q. Could you explain that a little bit
13 further, please?
14 A. The intent here was to evaluate the
15 geographic distribution of BMP implementation in the
16 basins draining to Lake Okeechobee and determine if
17 there was a statistically significant trend in
18 phosphorus load reduction. This is a problem because
19 of the high variability of hydrologic conditions and
20 considerable variability in distribution of
21 implementation.
22 Q. And what was the results of that work?
23 A. That BMPs are effective for reducing
24 phosphorus loads to Lake Okeechobee.
25 Q. You did find a decreasing trend?
42
1 A. A significantly decreasing trend.
2 Q. How significant?
3 A. Alpha less than point zero zero zero zero
4 one.
5 Q. That's very significant, is it not?
6 A. It is. Highly significant.
7 Q. What type of -- just in layman's terms,
8 what type of reductions were we talking about that
9 resulted from your interpretation of the data?
10 A. None.
11 Q. None?
12 A. No phosphorus load reductions occurred as
13 an effect of my interpretation of the data.
14 Q. No. But your interpretation of the data
15 revealed a reduction, did it not?
16 A. Yes. Sorry. A 20 percent load reduction.
17 Q. What types of just range of concentrations
18 of phosphorus are we dealing with in terms of water
19 draining into Lake Okeechobee?
20 A. It ranges from point 2 milligrams per liter
21 to slightly over one milligram per liter.
22 Q. Slightly over one point zero?
23 A. Yes.
24 Q. And what about phosphorus concentrations in
25 the lake water itself? What are the ranges that we
43
1 are looking at there?
2 A. Point zero five to point zero nine
3 milligrams per liter.
4 Q. Did you participate at all in what is
5 generally referred to as the Interim Action Plan and
6 the formulation of that plan?
7 A. No.
8 Q. The last item on that category on your
9 Curriculum Vitae says, "Develop strategy for field
10 standard operating procedures". Are we referring to
11 BMPs --
12 A. No.
13 Q. -- by that?
14 A. No, sir.
15 Q. What are you referring to there?
16 A. Sampling protocols for collecting water
17 quality and hydrologic data.
18 Q. And were you responsible for developing
19 those protocols?
20 A. No.
21 Q. Who was?
22 A. I don't believe anybody was specifically
23 assigned the task of developing those protocols.
24 Q. They were developed, were they not?
25 A. They have never been published as such.
44
1 Q. But were they developed?
2 A. Yes.
3 Q. Were they implemented?
4 A. Yes.
5 Q. Who participated in the development of the
6 protocols?
7 A. Many individuals of staff; of District
8 staff.
9 Q. Any outside consultants?
10 A. Not that I am aware of. The development of
11 the standard protocols is an ongoing effort that
12 depends on our monitoring strategy as well as
13 equipment. It also depends on what regional area and
14 what projects are included. There is generally a
15 project specific standard operating protocol, and I
16 was involved with those associated with monitoring
17 dairies and the basins north of Lake Okeechobee.
18 Q. Okay. The next item on your CV, '86 to
19 '89, perform water quality data interpretation, is
20 that the same item we just discussed?
21 A. Yes.
22 Q. And design and develop comprehensive water
23 quality monitoring program, what was that program?
24 A. That was the expansion of our monitoring
25 program in the basins north of Lake Okeechobee from
45
1 an ad hoc monitoring of ambient water quality to a
2 program designed to elucidate the impacts of
3 implementation of BMPs on dairies and beef pastures.
4 Q. And none of this work involved anything
5 south of Lake Okeechobee then?
6 A. No. I have not been involved in any
7 monitoring program designed south of the lake.
8 Q. Have you been involved in the
9 interpretation of any water quality data south of the
10 lake?
11 A. Only as it was directly related to the work
12 of Forest Izuno and Del Botcher.r. They had field
13 projects on four sites, and I looked at their data
14 fairly closely. But in terms of looking at ambient
15 measures throughout the basin, I did not interpret
16 work on interpreting that data in a general sense.
17 Q. When you say "in a general sense", that
18 leads me to believe that you did do something there.
19 Can you tell me what you did?
20 A. Yes.
21 Q. Please do so.
22 A. I did not do an analysis of water quality
23 on a basin scale, as I did north of the lake.
24 However, in development of the phosphorus budgets for
25 the EAA, I looked at the data to try to determine
46
1 concentrations and loads in the system from published
2 information. In short, I reviewed the data with a
3 very specific goal.
4 Q. Which was to develop a phosphorus budget
5 for the EAA?
6 A. Right.
7 Q. Did you actually prepare a phosphorus
8 budget for the EAA?
9 A. Yes.
10 Q. What was the purpose of that budget?
11 A. The intent of that budget stems from a
12 mandate given to us by Lake Okeechobee Technical
13 Advisory Committee to identify sources and source
14 areas of phosphorus draining to Lake Okeechobee. And
15 at that time, the northern half of the EAA was
16 considered part of the Okeechobee basin, and thus,
17 part of the Okeechobee SWIM planning effort, so the
18 intent of the budget was to identify probable sources
19 pursuant to identifying methods for reducing those
20 sources.
21 Q. Did the budget encompass the entire EAA or
22 only those portions draining to Lake Okeechobee?
23 A. We built the budget to incorporate the
24 entire basin because it was a basin scale analysis
25 and we lacked sufficient specific information to
47
1 construct budgets for specific sub-basins within the
2 EAA.
3 Q. So am I correct in assuming then that the
4 EAA budget that you prepared was not based on each
5 individual sub-basin?
6 A. Correct.
7 Q. It was just for the entirety of the EAA?
8 A. Yes, sir.
9 Q. And when did you prepare the budget, the
10 EAA budget?
11 A. Spring of 1989.
12 Q. Have you worked on it since that date?
13 A. Only minor work.
14 Q. When?
15 A. Periodically it becomes interesting, and
16 periodically I do additional analysis.
17 Q. At whose direction?
18 A. No specific direction. Various managers or
19 other people express interest in interpreting the
20 budget, and I do some additional work effort on
21 trying to specify certain parts of it in more detail;
22 however, it does not come as an assignment.
23 Q. Was the budget ever finalized; your EAA
24 budget? Did you ever finalize it?
25 A. No, I have not.
48
1 Q. What additional work needs to be done on
2 it?
3 A. I am not -- well, "finalized", to my
4 expectations, means producing a refereed journal
5 article publication describing the budget; and as
6 such, I want to reduce the uncertainty about some of
7 the estimates and do another review of available
8 information to ascertain that I have got the best
9 available information in the analysis.
10 Q. Was the EAA budget you prepared published
11 in any format?
12 A. No.
13 Q. To your knowledge, was it a part of the
14 1992 SWIM plan?
15 A. Not that I know of.
16 Q. Was it used, to your knowledge, in
17 fashioning any of the remedies contained in the SWIM
18 plan?
19 A. I do not know.
20 MR. BLANK: Maybe it would be appropriate
21 to take a five-minute break.
22 (Thereupon, a recess was taken.)
23 BY MR. BLANK:
24 Q. You indicated that there was some
25 additional work that you wanted to do with regard to
49
1 the phosphorus budgets regarding uncertainties about
2 some estimates. Can you identify which estimates you
3 are referring to there that are related to
4 uncertainties?
5 A. Well, in a general sense, I'd like to go
6 back and review all the data that had been used to
7 develop the budget and just do a recheck of all the
8 different data sets.
9 Q. And what data was used to develop the
10 budget?
11 A. Well, as you probably already know by
12 looking at the different materials on it, I used
13 information from many sources to develop the budget.
14 Q. Can you just in general describe those
15 sources?
16 A. Fertilizer sales records from TVA.
17 Q. From who?
18 A. Tennessee Valley Authority. The
19 International Fertilization Laboratory and Research
20 Center.
21 Q. These fertilizer sales records, did they
22 maintain records specifically related to farms within
23 the EAA?
24 A. No, sir.
25 Q. Why did you review those records?
50
1 A. Those records are based on sales of all
2 formulations of fertilizers sold by county within all
3 states. Of course, the stuff I was interested in
4 were the counties surrounding Lake Okeechobee. This
5 information was developed in response to developing
6 phosphorus budgets for the basins, for Lake
7 Okeechobee. As the EAA was a sub-set of those of
8 particular interest, and because we were stuck with
9 the quandary of how to separate out those portions of
10 the basins draining to the lake from the total EAA,
11 one of the concerns we had was to first build a
12 budget for the EAA. As we built the budget for the
13 EAA, it became its own analysis because there was the
14 interest in knowing what the budget was for; the EAA
15 specifically. And in the end, if I remember
16 correctly, we simply took an aerial fraction of that
17 for what goes back to Lake Okeechobee. And since the
18 analysis for Lake Okeechobee has focused on what is
19 going on north of the lake, we haven't gone back and
20 reviewed, trying to split out specific basins.
21 It would be an interesting analysis, but
22 first they have to complete development of the
23 geographic information data base that includes
24 wetlands use, historical patterns of cropping
25 rotation on sugar cane fertilization practices,
51
1 et cetera.
2 The data we used from TVA was for one year;
3 1987. I want to go back and look at least at the
4 last ten years of data to see what the trends in
5 usage of fertilizer are. I suspect that they have
6 not been constant. This is a farming area that has
7 varied considerably over time, and some major jumps
8 in programs occurred in the '60's and the '70's and
9 the '80's, so it is likely that the phosphorus budget
10 could be dynamic in nature.
11 Q. How did you take the sales records,
12 fertilizer sales records, and determine an amount of
13 fertilizer that was used within the EAA?
14 A. That's an involved process. I don't
15 remember the exact details. I'd have to read through
16 exactly how we did it, which is in there, in writing.
17 But generally, we went, we looked at the amount of
18 land use in specific crops, we looked at the
19 recommendations of fertilizer for those specific
20 crops, and estimated how much phosphorus fertilizer
21 was used, based on the cropping times, the number of
22 acres in that crop on the average, over a five-year
23 period for which it had taken SCS and the District to
24 accumulate land use information. We subtracted away
25 from the fertilizer purchases the amount of
52
1 fertilizer used for lawns, the amount of fertilizer
2 used in the agricultural areas not in the basin,
3 probably contribution of fertilizer purchases in
4 Hendry County and surrounding counties, and compared
5 that to the amount of fertilizer that was estimated
6 to be used based on cropping and recommendations, and
7 found a very close approximation between the two
8 different sets of data. And we used that for our
9 estimate.
10 Q. Did you obtain any information or records
11 from farmers within the EAA in terms of fertilizer
12 usage?
13 A. Not directly. We obtained indirect
14 information in terms of did they follow
15 recommendations, did they have their own set of
16 recommendations, did they do it like grandpappy and
17 pappy did before them, and checked to see if that
18 anecdotal information conflicted or confirmed our
19 previous interpretation of land use and cropping
20 practices and fertilizer usage, and we found it
21 pretty much went in the same line.
22 Q. All right. Are there any other estimates
23 contained in the budget that you think need
24 refinement?
25 A. Or at least verification. Refinement, I
53
1 don't expect that many of the numbers that we used
2 are going to change grossly. What we want to do is
3 when we verify the numbers, determine how certain
4 they are on the limited data that can be made
5 available and how variable the estimates are likely
6 to be through time. We don't expect that the gross
7 numbers will change. Another set of data that we
8 would like to verify is transport of phosphorus in
9 ash from both field burning of cane and from the
10 mills.
11 Q. Does your budget, right now, or the budget
12 you prepared, contain estimates for transport of
13 phosphorus in ash?
14 A. Yes.
15 Q. And how did you arrive at that number?
16 A. Those two numbers? The one from -- there
17 are two numbers. One is the composite of the mills
18 and refineries. It is my understanding that all of
19 the cane materials that arrive at the mills are
20 burned in the processing of sugar. At least raw
21 sugar. And of that, it is all converted to an ash.
22 And their system for ash recovery is required to
23 recover 95 percent of the ash; and, therefore, the
24 estimate of how much phosphorus leaves the mill would
25 be five percent of all the phosphorus that comes into
54
1 the mill.
2 Q. And that would leave the mill in ash; is
3 that what you're saying?
4 A. Yes, sir.
5 Q. In other words, it would be airborne?
6 A. Right.
7 Q. Did you do any studies or how did you
8 determine what happened to that airborne ash?
9 A. I cannot remember at this point how we
10 handled those numbers. I haven't had a chance to
11 review that analysis. I believe we assumed a certain
12 percent would be, and a small percent would be
13 dropped locally, but most of it would be carried out
14 of the EAA on whatever the local wind patterns were
15 that day either to the east coast or over Lake
16 Okeechobee or out to the EPA. I believe there exists
17 data that the farmers are required to collect to
18 determine the ash contents in the air for EPA
19 standards, but I have not seen those data sets.
20 Q. This would be data on the ash leaving the
21 mills or refineries?
22 A. Right. And it is my understanding that
23 there are a handful of EPA required sampling stations
24 in the EAA to evaluate the amount of ash that is
25 being distributed primarily for health reasons.
55
1 Q. You say EPA again. Did you mean --
2 A. Now I mean the Environmental Protection
3 Agency requirements.
4 Q. Okay. Have you reviewed any data from any
5 of the EPA stations?
6 A. No, I have not. Unfortunately, I have not
7 had the opportunity to hunt that data down. I have
8 only heard of rumors that it exists.
9 Q. Do you know where the stations are located?
10 A. No, sir. That information will be used in
11 a peripheral sense to confirm the distribution of ash
12 from the mills. It cannot directly confirm or deny
13 the generation of phosphorus and ash from the mills
14 because it is not likely that those sampling stations
15 will collect a representative amount of the ash that
16 falls or is produced from the mills. So it can only
17 define one category of ash fall-out.
18 Q. Would you, from that data, anticipate you
19 would be able to distinguish ash leaving the mill
20 from ash resulting from the burning of cane fields?
21 A. I'm not sure. The characteristics of the
22 ash should be different because the material in the
23 field will be differed from the material burned at
24 the mills, and the degree of completeness of
25 combustion should be different. It depends on the
56
1 construction of the sampling device and when it
2 samples and how. It is possible to separate it. I
3 don't know if the data will be good enough to do
4 that. It depends what parameters they measure from
5 the data from the samples collected.
6 Q. All right, sir. Are there other areas of
7 uncertainty that you can identify at this time?
8 A. Well, as I say, every one of the numbers
9 used in the analysis has an uncertainty associated
10 with it, and they all should be quantified.
11 Q. Let me show you a document that we will
12 mark as Number 2.
13 (The document was marked
14 Flaig Exb. No. 2.)
15 BY MR. BLANK:
16 Q. Can you identify this document?
17 A. This is a summary of the phosphorus budget
18 that I prepared for the 1989 Everglades SWIM Plan.
19 The intent was to produce a very brief analysis of
20 the fate of phosphorus.
21 Q. Now, on the first page of this document,
22 the last sentence that starts with, "The list of
23 exports attempts to account for marketable goods and
24 waster material", there is a paren; "ask Eric". Do
25 you know who actually wrote that sentence?
57
1 A. I believe these are edits that were made by
2 Dave Swift.
3 Q. What were you referring to or was
4 Mr. Swift, if you know, referring to in terms of
5 marketable goods? Is that the agricultural product
6 itself?
7 A. Yes.
8 Q. So that would be sugar or vegetables or
9 some commodity?
10 A. Or sod or furfural.
11 Q. And what about waster material? What would
12 that refer to?
13 A. Well, I suspect he meant to say waste.
14 Waste materials would be the ash, sludge from the
15 mills, poor quality water coming from other areas, as
16 well as for the vegetables. The trimmings before the
17 vegetable is sent to market, such as with carrots,
18 you are going to -- you may or may not cut off the
19 tops and, therefore, where does this pile of tops go?
20 And in the specific case of rice, the chafe from the
21 rice may or may not be a marketable good and it may
22 or may not be a waste product, depending on the
23 market. And, of course, all this material, it may or
24 may not leave the EAA once you account for the
25 phosphorus that's in it.
58
1 Q. So that is another area of uncertainty in
2 terms of what actually happens to that waste material
3 and whether it is exported from the EAA in some
4 fashion; is that correct?
5 A. That becomes a part of the uncertainty
6 involved in estimating exports.
7 Q. The next sentence, "The summation of
8 sources and sinks does not represent a mass balance,"
9 is that a correct statement?
10 A. Yes.
11 Q. Why doesn't it represent a mass balance?
12 A. Without being able to do a complete
13 tracking of imports of all transformations of
14 phosphorus, it is not clear that we have been able to
15 obtain all the measures. When one wants to claim a
16 mass balance, they have been able to track all
17 particles of phosphorus coming in and all particles
18 of phosphorus leaving and account for the storage.
19 In this analysis, we were able to track the
20 things that are commonly measurable and have been
21 reported in some form or another. We cannot take
22 account for the things that are unmeasurable or
23 processes we are unfamiliar with. And I believe
24 that's what it says in the following sentence.
25 Q. Would that primarily relate to the export
59
1 aspect of your budget or are there uncertainties also
2 with regard to the import?
3 A. Well, again, the definition of uncertainty
4 is a statistical definition of how well do we trust
5 any of our data? And in any global form of analysis,
6 there is going to be where you're taking sub-samples
7 to quantify those global mass transfers, there is
8 going to be uncertainty, just in the statistical
9 nature of the data, the distributions of the data.
10 We can speculate with each one of the sources that we
11 were looking at -- imports, exports, transport out of
12 waste materials -- that there are probable sources of
13 uncertainty, and these we don't know about, which are
14 the most important. We wouldn't know until we know a
15 total mass budget. And, of course, I'm not sure if
16 that's even possible; to completely know where the
17 mass has been.
18 There is some concern that the waste
19 products from the vegetables and where they are
20 deposited and where they enter either the flow stream
21 or the soil could represent a significant
22 uncertainty. On the other hand, we may find that
23 really there is very little phosphorus in those
24 materials. The amount of materials is small, it
25 remains in the field, and, therefore, it becomes part
60
1 of one of the other pools of stored phosphorus, and
2 it is very small, say, compared to mineralization
3 rates. So once again, when we go and we look for
4 sources and sinks, we start with no influence as to
5 the relative magnitude.
6 Q. Is there anyone with the District that is
7 attempting to answer some of these questions that you
8 have just outlined?
9 A. I don't know.
10 Q. All right. Under the category of sources,
11 the first sentence there has some strikethroughs
12 after saying that, "Fertilizer is the single greatest
13 import source of phosphorus to the EAA". Do you know
14 why that sentence -- or actually the next two
15 sentences -- were struck?
16 A. I have no idea why Dave Swift was editing
17 this in this fashion.
18 Q. The numbers that were contained in the
19 strikethrough sentences, do they represent correct
20 numbers, as far as you know?
21 A. Yes.
22 Q. Did you arrive at an estimate in terms of
23 preparing the budget of the amount of fertilizer
24 applied per acre for sugar cane fields?
25 A. Could you restate that question?
61
1 Q. Yeah. Well, let me -- the next sentence
2 after the strike-through says, "In Hendry County
3 approximately 525 Tons phosphorus were used on sugar
4 cane in the EAA" and then there is a strike-through
5 for what appears to be "60,000 acres at 17.5 pounds
6 per acre". What I am wondering is whether that
7 pounds per acre figure was derived also for other
8 areas than Hendry County.
9 A. Well, in the following sentence it shows
10 the same strike-through relative to Palm Beach
11 County.
12 Q. Yeah. With the same number in terms of
13 pounds per acre; is that correct?
14 A. Correct. So the question is did we do the
15 analysis from the perspective of pounds per acre
16 recommended?
17 Q. Yes.
18 A. That was one form by which we estimated how
19 much phosphorus was used.
20 Q. Did you attempt to verify that pounds per
21 acre figure with any of the farmers within the EAA?
22 A. Indirectly. Again, given the acreage of
23 sugar cane farmed in the EAA and the number of
24 individuals involved in farming and, of course, the
25 variations in their rotational characteristics and,
62
1 therefore, how much phosphorus they would use on the
2 planted crop versus the various ratoons and soil
3 type, et cetera, et cetera, individual anecdotal
4 information from specific farmers would neither --
5 would not be useful for confirming a basin average
6 value.
7 We did check with various principals and
8 various corporations, as well as knowledgeable
9 experts at the Belle Glade experiment station, as to
10 whether these were reasonable numbers to use, and at
11 the time they seemed reasonable and acceptable, but
12 there was a very large variation in what's actually
13 been done. Some people don't fertilize at all,
14 either by soil test or by instinct, some people
15 fertilize a lot, either by soil test or that's the
16 way it's done, and there is no specific rule. It
17 depends also on the cropping sequences. If they do
18 it after a certain vegetable crop, they will or they
19 won't.
20 So, although we made an effort to
21 confirm -- Do you put on 200? No. Do you put on
22 zero all the time? No. -- and then narrow it in
23 from there as to what was a reasonable estimate, it
24 would be useful to have specific fertilizer usage
25 data. There was some question as to whether even the
63
1 best growers had the specific year-to-year
2 information of what they specifically used on their
3 ownership.
4 Q. These numbers that are contained in this
5 paragraph are annual numbers, are they not? This is
6 an estimate of annual usage?
7 A. Correct.
8 Q. Did you specifically contact, for example,
9 U. S. Sugar Corporation and ask them if they had
10 records concerning fertilizer use?
11 A. No, we did not, because at the time it was
12 indicated that we would not get any sort of
13 reasonable response.
14 Q. Who indicated that to you?
15 A. Everyone we inquired that of. We talked to
16 people that were knowledgeable about what U. S. Sugar
17 does; in particular, the experts at the University of
18 Florida. And Carolyn Fonyo, who was on contract with
19 us, to help us develop the budgets for the whole Lake
20 Okeechobee basin, also inquired of the people that
21 she knew. But, at the time we were developing this
22 budget, it was considered fruitless to try to get
23 specific numbers. We did ask specifically of
24 representatives from the Florida Sugar Cane League if
25 we could get such numbers. They said, "Oh, yes, of
64
1 course", and we didn't receive any numbers.
2 Q. So if numbers that we have in here -- let
3 me see if I understand exactly how your numbers were
4 derived. Did you work backwards from a recommended
5 application rate per acre and multiply that number
6 times the entire acreage to get to your total of
7 fertilizer used in the EAA?
8 A. Yes.
9 Q. Okay. And then what did you do to attempt
10 to verify that total number?
11 A. Well, we compared that against actual
12 purchases to see if they were reasonable, and they
13 appeared to be in the same degree of uncertainty.
14 Q. And the data that you got on actual
15 purchases, was that on a per-farm basis?
16 A. No, sir. That was on a county basis. And
17 then we had to derive from that the probable usage
18 within the EAA.
19 Q. So you received a number of the total
20 pounds of phosphorus sold within a given county?
21 A. Broken out by fertilizer formulation.
22 There's something like 200 formulations used in this
23 county. Some of those are quite clearly used for
24 lawns, some are quite clearly used for various
25 vegetables crops, and there are some that are quite
65
1 clearly used for sugar cane.
2 Q. Okay. How did you know that fertilizer
3 sold within a particular county, let's say Palm Beach
4 County, was actually used within Palm Beach County?
5 A. There is no proof from looking at the
6 specific data. One has to look at the surrounding
7 county data in terms of looking at Broward County and
8 Hendry County and Martin County and Okeechobee
9 County. There is still the possibility that some
10 fertilizer mill in the Glades could be purchasing and
11 could be manufacturing and directly delivering to a
12 grower in Palm Beach County and we would not be able
13 to account for that. However, indirectly, by looking
14 at the usages in counties, and specifically that the
15 other surrounding counties do not have the crop types
16 that Palm Beach County and the eastern parts of
17 Hendry County have, it was fairly clear that those
18 fertilizer purchases were not ending up in the EAA;
19 that the fertilizer use in the EAA was primarily
20 restricted to purchases in Hendry County and Palm
21 Beach County. As such, though, it would be useful
22 and appropriate to go back through the whole list of
23 formulations, across a series of years, and compare
24 directly between the formulations and the acreage of
25 crops, and come up with a tighter correlation between
66
1 purchases and usages.
2 At one time it was possible to work with
3 fertilizer manufacturers and confirm with them where
4 the purchases from their various offices or mills was
5 being used, and at one point in 1988 International
6 Minerals Corporation, for instance, was quite happy
7 to sit down with us and talk to us about where the
8 purchases of fertilizer from their groups ended up.
9 Now, I don't know how specific that information would
10 have gotten, and we were unable to follow up on it,
11 so I'm not sure how much we would have gotten,
12 because in some sense this is proprietary
13 information, and I'm not sure how much of it would
14 have been shared with us in the end.
15 Q. What about the University of Florida people
16 you were working with; in particular, IFAS? Did they
17 have more accurate records in terms of actual usage
18 on a per-farm basis?
19 A. Well, that's where the primary information
20 we got came from. Carolyn Fonyo, again, was on
21 contract with us to develop the budget, and she
22 interviewed farmers, county extension agents, various
23 growers, as well as the research experts within the
24 University of Florida, both in Gainesville and at the
25 experiment stations. She confirmed, to the best of
67
1 her ability, what the usages were.
2 Q. Okay. So you feel fairly comfortable that
3 your 5600 tons of phosphorus per year was an accurate
4 number at the time you prepared your phosphorus
5 budget?
6 A. I believe two things of the data; best
7 available information, and within the order of
8 magnitude it's correct.
9 Q. Within what order of magnitude?
10 A. It could be, in a sense you know, 6,000.
11 It could be, in a sense, 5200; but I think 5600 is a
12 good number.
13 Q. So you think you're within 10 percent?
14 A. I believe so.
15 Q. The next paragraph, "Phosphorus found in
16 precipitation is an important import source". Do you
17 concur with that statement?
18 A. Yes.
19 Q. How did you measure phosphorus in
20 precipitation? How did you derive your numbers for
21 the budget?
22 A. With this I have to refer to work that was
23 completed by Jim Grimshaw at the District. There has
24 been considerable argument and discussion over what
25 are reasonable phosphorus concentrations in rainfall,
68
1 and I asked him to provide me with what he thought
2 was the best estimate, and I simply multiplied that
3 by the volume of rain that lands on the acreage of
4 the EAA to arrive at a loading. Specifically,
5 though, I did not investigate the various means by
6 which the precipitation were collected and analyzed.
7 Q. And you didn't do the analysis yourself?
8 A. No, sir.
9 Q. The next sentence reads, "Bulk
10 precipitation, both-dry fall and rainfall, has been
11 collected for a 14-year period for the EAA". Do you
12 know who collected that data?
13 A. I think it came from various sources. At
14 this point, I don't specifically remember.
15 Q. Would that be data actually collected by
16 the District?
17 A. I believe it would include District data,
18 University of Florida data, I think there is a NOAA
19 station involved. I don't remember.
20 Q. And what about USGS? Would they have --
21 A. They may have been involved at that stage.
22 Various players have been involved in that. Again, I
23 would have to defer to Jim.
24 Q. The next sentence, "The average of the
25 annual phosphorus load is 102 tons per year for the
69
1 532,000 acres of permitted agricultural land"; was
2 that a figure that was derived by Mr. Grimshaw?
3 A. Which figure?
4 Q. The 102 tons per year.
5 A. No.
6 Q. Is that your number?
7 A. Yes.
8 Q. How did you calculate that number?
9 A. The average rainfall times the average
10 amount of land times the average concentration.
11 Q. Okay. And what did you mean by "permitted
12 agricultural lands"?
13 A. We use the acreage of land that has water
14 use permits with the District for agricultural
15 activity.
16 Q. And that is the difference between that and
17 the next number, the number in the next sentence, the
18 632,000 acres just described as total muck lands.
19 A. Right. I don't remember specifically, but
20 I believe it also includes the Holey Land the
21 Rotenberger tract and other areas that are not
22 permitted for agricultural use. Areas around the
23 various towns, various out-acreages that were not
24 being farmed.
25 Q. Can you tell me why the average annual
70
1 phosphorus load would increase as the area increased?
2 A. I believe that's simply a function of as
3 you increase area, you increase the amount of
4 precipitation that has occurred within.
5 Q. Okay. So it is just a straight calculation
6 based upon an average --
7 A. Right.
8 Q. -- number times acres?
9 A. Right. There is no other relationship.
10 Q. Do you have any idea of how many sampling
11 stations were located within the EAA to measure
12 rainfall and analyze the phosphorus contents of it?
13 A. I don't recall.
14 Q. And there is, at the end of that, the last
15 sentence of that paragraph, there are two words; "per
16 acre", with a question mark. Do you know what that
17 refers to?
18 A. Well, again, Dave Swift was editing this
19 section to match with the editorial style of the rest
20 of the SWIM plan, and the only thing I can guess is
21 he wanted certain things on a per-acre basis, as
22 opposed to a general basis. Since this data, the
23 primary data used in this was average for the basin,
24 it is really not proper to report it as per acre.
25 Q. Okay. Do you recall what the average
71
1 concentration of phosphorus and rainfall was that was
2 utilized for these calculations?
3 A. No, I don't. It is in a different
4 document.
5 Q. The next paragraph refers to, "Water
6 withdrawn from Lake Okeechobee for irrigation
7 contains phosphorus load". Did you make any estimate
8 on the total load that would be imported into the EAA
9 based upon withdrawals from Lake Okeechobee?
10 A. Yes.
11 Q. Is that the 32 ton figure that's contained
12 in that paragraph?
13 A. Yes. Let me correctly define that. The
14 load estimate is for the structures on Lake
15 Okeechobee for the EAA. The loadings are calculated
16 by a different group. I accepted their numbers.
17 Q. Okay. What group made those calculations?
18 A. That would be on your data management or
19 water quality analysis group.
20 Q. Who would be in charge of those groups?
21 A. Currently?
22 Q. Uh-huh.
23 A. Dr. Leslie Wedderburn.
24 Q. Do you know who within those groups
25 actually provided you with the information?
72
1 A. Personnel have changed quite a bit. I'm
2 not sure exactly who was responsible for the
3 calculations. These were data that were being
4 prepared for the '89 SWIM plan, and as the data
5 became available, I simply adopted the commonly
6 accepted data for consistency.
7 Q. Do you recall whether your budget was
8 contained in the '89 plan?
9 A. I don't remember. I don't believe it was.
10 Q. With regard to withdrawals or water from
11 Lake Okeechobee entering the EAA, did the 32 ton
12 number relate exclusively to irrigation withdrawals
13 as contrasted to pass-throughs from Lake Okeechobee?
14 A. To best answer that question, I would want
15 to back up and mention that I believe the actual
16 numbers we were working with is -- there were 52 tons
17 leaving the lake going south each year, and there
18 were, over that 14-year period, an average of 20 tons
19 being back-pumped to the lake for flood control.
20 Now, we know the 20 tons going back to the lake was
21 for flood control, but, of the 52 that came south at
22 that time, there was not a clear analysis of how much
23 was used for irritation versus pass-through to the
24 areas south. And in that light, I'm not sure if I
25 would want to directly subtract the 20 off of the 52
73
1 and then say well, 32 should be the ones analyzed for
2 going south versus internal consumption. I realize
3 that's not a direct answer to your question.
4 Q. No. I am just wondering whether there is a
5 way to get a better handle on the number that is
6 actually used for irrigation versus what was
7 pass-through water.
8 A. Right. Well, there is, and it is my
9 understanding that some attempt at that analysis has
10 been made since I prepared this. One can look at the
11 distributions of releases from the lake relative to
12 pumping on the south end of the EAA. Since all water
13 leaving the EAA has to be pumped out, one could do an
14 analysis to show when it was released versus when it
15 was pumped and fairly accurately define how much was
16 passed through, as opposed to internal use.
17 Q. All right. And your tonnage figure for
18 phosphorus coming from the lake, was that based upon
19 the volume of water times average concentration of
20 phosphorus?
21 A. I do not remember the exact formulation of
22 the calculations, but I have believe that the way
23 they were calculated is they took the biweekly or
24 monthly sampling. Actually, I should say I don't
25 know. I speculate that we have autosamplers at each
74
1 of the pumps, as well as doing monthly or biweekly
2 sampling, and those data were used to estimate loads
3 based on pumping rates over those short periods of
4 time to estimate the loads coming there. So it was
5 using the specific data, as opposed to average
6 values. One could pose that they used average lake
7 concentrations and total pumpage and estimated the
8 loads. They did not do that. They used more
9 specific data. The actual formulation of those load
10 calculations I am unfamiliar with.
11 Q. Do you know what period of record was used
12 for the calculation on the load from Lake Okeechobee?
13 A. I believe it was the same 14-year period
14 that was used as the base period for the SWIM plan.
15 Q. Did the District have autosamplers back in
16 1973?
17 A. I don't know.
18 Q. When you say "autosampler", can you
19 describe what that is?
20 A. An automated water sampling device of
21 several configurations basically set to take samples
22 either based on a time increment or on a pumpage
23 increment, and I cannot say that I have a record, I
24 am knowledgeable about what protocols were used at
25 those pump stations.
75
1 Q. Is this also what is commonly referred to
2 as a composite sample?
3 A. They would be composite samples.
4 Q. As contrasted to a grab sample?
5 A. Correct.
6 Q. You said that the autosamplers were
7 designed to sample based upon either a time increment
8 or a flow increment.
9 A. That's generally how they are configured.
10 Q. Do you know, with regard to the ones
11 measuring water out of Lake Okeechobee, whether those
12 were based upon a time interval or a flow interval?
13 A. I don't have personal knowledge of how they
14 have been configured over the period of record.
15 Q. Well, if they were based on a volume of
16 flow, how often would you obtain a sample from the
17 autosampler?
18 A. Still, again, depends on how they were
19 configured. Several ways they could be configured;
20 depending on the amount of water they were willing to
21 capture and the device they were using. Better off
22 to talk to the person who is responsible for that.
23 Q. Yeah. Well, he's not here right now. What
24 I am wondering about is how frequently would a sample
25 be taken? Daily, weekly?
76
1 A. I'm not sure. I would assume it would be --
2 MR. COUSINS: Don't assume. If you're not
3 sure --
4 THE WITNESS: I don't know.
5 BY MR. BLANK:
6 Q. Okay. What about in the instance of grab
7 samples? Do you know how frequently they were taken?
8 A. Our general pattern is either biweekly or
9 monthly, but I don't know the schedule for those
10 stations.
11 Q. Do you have any idea how, if you had
12 bimonthly samples -- let's say two samples a month on
13 water flowing from Lake Okeechobee and those samples
14 contained different concentrations, let's say one was
15 at 100 and the other one was at 150 -- am I correct
16 that you also had daily flow records --
17 A. Yes.
18 Q. -- Okay.-- how would one have made an
19 interpretation of daily flow records, versus
20 bimonthly water quality calculations, to determine
21 total load for the month?
22 A. Again, I do not know how it was
23 specifically calculated for that. And that's been
24 published in other areas. I simply accepted the data
25 that they had developed.
77
1 Q. Okay. Were there other sources of
2 phosphorus as a part of your budget that aren't
3 contained in this summary? We went through Lake
4 Okeechobee precipitation and fertilizer.
5 A. I don't believe so.
6 Q. What about seepage?
7 A. It was not included.
8 Q. Is there a reason why it wasn't included?
9 A. We had no quantifiable numbers.
10 Q. Do you know of anyone that has measured the
11 amount of seepage entering the EAA?
12 A. No, I have no one who has measured seepage.
13 Q. And the next category, "Internal sources",
14 this relates to oxidation of muck soil; is that
15 correct?
16 A. Yes.
17 Q. And there is a number there which says what
18 60 pounds of phosphorus per acre per year?
19 A. Yes, sir.
20 Q. How was that number derived?
21 A. I have not reviewed the direct
22 calculations, but I believe that's an average value
23 for oxidation for the entire EAA.
24 Q. Who performed those calculations?
25 A. Well, there's two parts: The last part in
78
1 terms of -- those are estimates that were derived
2 from research conducted by the University of Florida,
3 where they estimated the rate, the average rate, of
4 oxidation, times the amount of phosphorus that
5 occurred in a given volume of soil to estimate what
6 the average release of phosphorus would be on a per
7 acre basis.
8 Q. Were these actual field experiments that
9 were conducted in terms of oxidation rates?
10 A. They were field measurements taken. I
11 don't recall if specific long-term experiments were
12 conducted to specifically define local oxidation
13 rates.
14 Q. Do you know if the measurements were taken
15 on fertilized versus unfertilized fields?
16 A. No.
17 Q. You do not know?
18 A. I do not know.
19 Q. Now, how does oxidation of muck soil differ
20 from mineralization of the muck?
21 A. It depends on your definition. Oxidation
22 generally refers to the overall subsidence, which
23 would include a physical component as well as a
24 mineralization component. The oxidation is just the
25 decrease in volume of the muck, whereas
79
1 mineralization is more specifically defined toward
2 the behavior of phosphorus within the muck.
3 Q. Are we talking about two different rates of
4 phosphorus release or source here; one for oxidation
5 and a different one for mineralization?
6 A. No. We are -- oxidation is primarily a
7 description of the change of the muck soil itself,
8 and mineralization is the more specific change of
9 phosphorus within that muck.
10 Q. And can you tell me how the figure of
11 19,500 tons of phosphorus per year was derived at
12 relative to mineralization?
13 A. Again, it is the amount of phosphorus
14 released through oxidation times the number of acres
15 affected.
16 Q. Through oxidation?
17 A. Right. Oxidation is the process of change
18 of the muck soil, and mineralization would be the
19 release of phosphorus during oxidation.
20 Q. Okay. And the next sentence, "However, the
21 mineralized phosphorus is likely to be absorbed to
22 the soil or immobilized by soil microbes," what was
23 the basis of that statement?
24 A. A general understanding of soil processes.
25 Q. Is that a statement that you wrote?
80
1 A. Correct.
2 Q. Okay. And can you describe that soil
3 process that would result in immobilization or
4 absorption?
5 A. Yes.
6 Q. Please do so.
7 A. The mineralization process would be the
8 breakdown of the organic matter in the soil, and it
9 is presumed that the primary product would be a
10 single phosphorus molecule as it mineralizes and
11 breaks down. However, the whole 19,000 tons of
12 phosphorus does not occur as phosphorus molecules
13 available for transport because the oxidation process
14 is primarily microbially mediated release of
15 phosphorus and the phosphorus is incorporated into
16 the microbes, as they eat the soil, as it were. So a
17 large portion of the phosphorus is just converted
18 into microbial biomass, and as the microbes die, it
19 is released to the soil as an organic form, which
20 either can absorb physically to the particles or
21 simply exist in the soils as an organic phosphorus
22 molecule. The phosphorus that's released by the
23 microbes, but not incorporated, will absorb to the
24 soil particles directly. In either case, a majority
25 of the phosphorus simply combines in soil particles
81
1 in a different form, but remains in the soil profile.
2 There is some evidence from specific field
3 studies that during oxidation, under fertilized and
4 unfertilized fields, the phosphorus, as determined by
5 fractionation procedures in laboratories, converts
6 from an organic form to an inorganic form through
7 subsidence and mineralization, and reaccumulates in
8 the soil profile. So as the depths of the soil
9 decreases with oxidation, the phosphorus converts
10 from an organic form to an inorganic form, and it may
11 move in the profile -- the profile of the soil simply
12 being the depth of the soil -- it may move from an
13 upper to a lower strata, but simply remains in the
14 soil. And that's a general view of the processes
15 involved.
16 Q. In its inorganic form, is it available for
17 uptake by vegetation?
18 A. It may be or it may not be, because in the
19 mineral form, it may form a precipitate that's
20 unavailable, just like rock phosphate, or it may be
21 simply absorbed in the soil particles, in which it is
22 highly labile.
23 Q. You mentioned some actual field experiments
24 or studies that were conducted with regard to this
25 phenomenon. Who was it that conducted those studies?
82
1 A. Various researchers had conducted them. I
2 don't remember whether I have cited any in this
3 paper. Well, one individual who did some
4 tractionation was Ian Nicholson, which is cited in
5 the back of this write-up. I don't remember other
6 names directly.
7 Q. What about Reddy; did he do any? Ramesh
8 Reddy.
9 A. I don't remember reviewing any of his work
10 specific to this area at the time.
11 Q. I am just looking at your references, and
12 about halfway down on the first page there is a --
13 A. Two Rameshes.
14 Q. Yeah. One of them dealing with soluble
15 phosphorus released from organic soils.
16 A. I believe those are more generic
17 discussions.
18 Q. Okay.
19 A. And they are not based on specific data
20 from the EAA.
21 Q. And were you able to come up with any
22 accurate estimate of the amount of phosphorus due to
23 oxidation or mineralization that was actually
24 released to surface waters?
25 A. Could you restate the question?
83
1 (Thereupon, a portion of the record
2 was read by the reporter.)
3 THE WITNESS: I developed an estimate of
4 phosphorus released to surface waters; however,
5 there is no detailed experimental data, or I
6 reviewed no detailed experimental data that
7 showed that it resulted directly from oxidation
8 or mineralization.
9 BY MR. BLANK:
10 Q. How did you arrive at your estimate?
11 A. My estimates were based on field data
12 collected by CH2MHill in their 1977, 1978 work. I
13 don't recall if I used other information or not, but
14 I specifically remember theirs.
15 Q. Do you recall what that number was?
16 A. The number that sticks in my mind right now
17 is 600 tons.
18 Q. And this figure would be for the entire
19 EAA?
20 A. Yes, sir.
21 Q. And is this a number that would relate to
22 fertilized as well as unfertilized fields?
23 A. It would be a combination of all fields.
24 Q. Is the last sentence of that paragraph,
25 "Accurate estimates of the contribution of oxidation
84
1 to phosphorus loss are not available" still a correct
2 statement?
3 A. Well, I think I prefer the word "good"
4 estimate. The question of accurate simply infers an
5 acceptable, yet unidentified, level of uncertainty.
6 Everything is accurate within a measure of some
7 measure of uncertainty. But in the sense that there
8 are estimates available now that are more accurate
9 than the ones I used, I believe other data have been
10 developed since then, but I have not seen the data
11 sets.
12 Q. Are you aware of any data that has been
13 developed concerning phosphorus losses due to
14 oxidation from fertilized fields versus unfertilized
15 fields?
16 A. I'm not aware of any specific data sets.
17 It would be embarrassing to the scientific community
18 if such data sets had not been developed in the last
19 few years.
20 Q. All right. Are there any other internal
21 sources that you are aware of that we haven't
22 discussed?
23 A. Yes, there are.
24 Q. And what would they be?
25 A. They are not presented here in such a way,
85
1 but the mill water and residues from the mill would,
2 in a sense, represent an internal source, although
3 they could also be interpreted as the final outcome
4 of an import.
5 Q. Is that covered under the category of
6 exports? I see a heading there under cane mills.
7 A. Yeah. Perhaps that's included there. It
8 is a definition of what internal sources are. I
9 guess the only internal source would be the soil
10 itself and the others are represented under exports.
11 Although, if one was tracking individual particles of
12 phosphorus, there could be a mix. Anyway, they are
13 included under exports.
14 Q. All right. Under the export category there
15 is the distinction made between point sources and
16 non-point sources; is that correct?
17 A. Correct.
18 Q. Let's see. The third sentence of that
19 paragraph says, "Phosphorus losses from each field
20 consist of crop exports, leaching losses, and surface
21 runoff". Do you see that sentence?
22 A. Yes, sir.
23 Q. Okay. When you refer to crop exports,
24 you're talking about actually harvesting of the crop
25 and exporting the crop from the field or the EAA; is
86
1 that correct?
2 A. From the field.
3 Q. Okay. And what are you referring to by
4 "leaching"; the term "leaching losses"?
5 A. Those would be losses that would result in
6 sub-surface transport of phosphorus that would
7 probably not be measurable in local field ditches.
8 As you track the water, you can either measure it
9 coming off in the surface water either at the edge of
10 the field or the edge of the farm, but leaching
11 losses would be those that would be recovered
12 elsewhere; deep seepage that might show up at our
13 pump station in a large canal, but would not be
14 measurable as surface runoff.
15 Q. Do you have any estimate of the amount of
16 phosphorus that would be exported through leaching
17 losses?
18 A. Not specifically.
19 Q. When you say "not specifically", that
20 would, to me, indicate you do have some feel there,
21 but can you tell me what that would be?
22 A. The reason why I say "not specifically" is
23 the statement here about phosphorus losses from each
24 field is meant to be a general statement about mass
25 balances, and in trying to quantify a budget, what
87
1 kind of numbers you want to be able to elucidate, we
2 have some numbers for looking at large movements of
3 phosphorus and we have some specific field data that
4 shows leaching losses from that specific field, but
5 we do not have experimental data or field
6 observations that track the leaching losses from the
7 field and out from the EAA, so we have parts of the
8 picture, but not something that directly links.
9 Q. So you haven't been able to come up with
10 any sort of a good or accurate estimate of the amount
11 of phosphorus that would be exported through the
12 leaching mechanism?
13 A. Not specifically.
14 Q. Are we talking here about leaching losses,
15 are we talking about ground water movement?
16 A. That would be the end result. Right. It
17 wouldn't be ground water leaching, but in the end, it
18 would be the ground water transport of the
19 phosphorus.
20 Q. Which could potentially be collected by one
21 of the District canals, but be flowing below the
22 field drainage canal?
23 A. Exactly. Probably collected by our primary
24 canals. So in a sense, it will still be quantified
25 as the complete loss from the basin, but trying to
88
1 identify those losses relative to a specific field
2 would be difficult.
3 Q. Do you have any idea of -- assuming that we
4 are losing phosphorus through this leaching mechanism
5 and there is a percentage of it that's traveling
6 through ground water, would that movement through
7 ground water have an effect on the phosphorus content
8 of the water? Would it reduce the amount of
9 phosphorus from the point of time it left the field
10 until it entered a District canal?
11 A. It should.
12 Q. By virtue of the fact that it is traveling
13 through lime rock?
14 A. Calcareous rock with a potential sorptive
15 capacity for phosphorus.
16 Q. On the next page under the heading "sugar
17 cane", the second sentence says, "Approximately 60
18 tons per acre --
19 A. Correct.
20 Q. -- "total annual biomass are grown, and
21 34.2 tons cane per acre per year are processed".
22 Where was that information derived?
23 A. From those two data sources.
24 Q. From the Sugar Cane League and Gasho and
25 Shih?
89
1 A. Yes.
2 Q. Who are -- who is Gasho?
3 A. A graduate student, I expect, but it could
4 be -- I'm not sure.
5 Q. This is one of the reference items
6 contained --
7 A. Yes, sir.
8 Q. -- in the back of your report?
9 A. Yes, sir.
10 Q. And the next sentence, "Phosphorus uptake
11 is estimated at 16 to 22," what does "lbsp" mean?
12 A. It means a typo.
13 Q. Oh.
14 A. "Pounds phosphorus per acre" is what the
15 whole thing says, but the P has kind of wandered over
16 from the H.
17 Q. And this uptake that you are referring to
18 is phosphorus that is assimilated into the plan
19 itself as part of the growth cycle?
20 A. Correct.
21 Q. And further down there is a statement,
22 "Approximately 5 tons of ash per acre are released
23 into the atmosphere." Do you see that statement?
24 A. Yes.
25 Q. Where did that number come from?
90
