1 MS. HUGHES: Or small accidental spills. 



2 DR. AURAND: We will let the editors do that later on. That takes 



3 care of operational discharges. 



4 Accidental discharges: We have two, oil spills, gas and gas 



5 condensate blow-outs. Why do we have produced waters in accidental 



6 discharges? 



7 MR. LANE: That comes out with the rest. 



8 DR. AURAND: You meant produced water as a component of either oil 



9 spills or blow-outs. 



10 MR. LANE: Is it useful to define a spill? 



11 DR. AURAND: This is a game I've been playing in Florida for the 



12 last 6 months. I'm not interested in defining it. 



13 DR. TEAL: I don't yet know why we want to define a spill. 



14 DR. AURAND: I think one place to start is to differentiate 



15 between surface and benthic impact. 



16 DR. KRAEUTER: Do we want to differentiate between spill and blow- 



17 out? 



18 DR. AURAND: If you accept what we heard yesterday, by and large, 



19 the ultimate impacts seem to be the same because this stuff goes to the 



20 top. 



21 DR. KRAEUTER: I'm not willing to accept that. 



22 DR. AURAND: You didn't like it when they said that, but you just 



23 kept quiet because it was getting late; is that it? 



24 DR. KRAEUTER: They didn't provide very much evidence to suggest 



25 that their model was correct. 



26 DR. AURAND: Well, that's what you guys were supposed to evaluate. 



27 DR. RAY: What was the issue here, John? 



28 DR. KRAEUTER: If you spill oil on the surface, that is 



29 substantially different than oil riding through the water column in 



30 terms of the potential mixing of the toxic fractions into the water. A 



31 lot more can be mixed with water as opposed to that which is spread on 



32 the surface and then it's got to go down by mixing with surface waves or 



33 something, so for the toxic fractions, you have a lot more of it in the 



34 water.
