1 DR. GRASSLE: That's why the caveat, that the larvae have to 



2 normally prefer the deposition sites. That's where the higher organics 



3 will be. 



4 DR. TEAL: The deposition is always very low in the whole place. 



5 DR. GRASSLE: I was just saying that when they settle, they are 



6 settling in a place that at that moment is depositional . 



7 DR. AURAND: When you talk about high organics, are you talking 



8 about- - 



9 DR. GRASSLE: No, I'm not talking about high organics. I'm 



10 talking about something that affects the larval behavior in the 



11 settlement. I'm talking about concentrations that can be lower than 



12 those that would cause toxicity. It could be narrow. I'm not talking 



13 something that usually you worry about in the sense of an effect on-- 



14 DR. AURAND: Most of the drilling muds and cuttings are clays. 



15 DR. GRASSLE: There is an oil component. It is different from the 



16 normal stuff that is going in there. It is certainly measurable that 



17 there is some organic component that is somewhat different from the 



18 natural sedimentation. 



19 DR. TEAL: The drill muds on the surface would taste different 



20 than they would normally, yes. 



21 DR. GRASSLE: Yes. 



22 DR. RAY: Most of your organic compound is lignin sulfanates. 



23 That's the primary organic compound of the drilling fluids. 



24 DR. GRASSLE: It's those lignin type things. I guess that's the 



25 highest concentration, but there is a concern about concentrations that 



26 could have an effect on behavior of larvae, even though they are ^ery 



27 low toxicity. 



28 DR. AURAND: Are we ready to move on to the produced water? 



29 DR. TEAL: I do not think we need to worry about the sewage; let's 



30 talk about the produced water. 



31 DR. AURAND: Do you want to avoid any comments on it at all, or 



32 just say they are minor problems? 



33 DR. TEAL: Well, they are minor in relation to these others.
