To: cc: Subject: Robert F PinchoVDEV/AE/DuPont@DuPont Barbara S Larsen/AE/DuPont, Daryl P Cobranchi/ABDuPont@DuPont Re: Mulit Media Consent Order APFO data requirements Q Barbara Larsen, Daryl Cobranchi and I designed an experiment to get headspace concentrations (see your note below). Barbara has evaluated these systems for calibration standards, ordered the headspace laboratory ware, and is proceeding with the feasibility study.

I'd appreciate it if I had all the data in hand no later than December 10th. Of course, the earlier the better. I have the data for the item in Green (Thanks Debbie).

This order, as many of you know, will require us to submit a lot of data concerning AFPO and our emissions of APFO to the state agencies. To make sure that we all understand our role in getting these data put together and submitting it to the State in the time stated in the order, a lot of coordination needs to be in place. Though the final wording of the order isn't known yet, the following table outlines the requirements, responsibilities, and the tasks to be completed. All items except the Mary Kaiser's analytical work will need to be supplied to the State within 30 days of the effective date of the Consent Order.

Please get all the data to me and I will work with our legal representation to develop the communication package(s) that we send. 1will let you know when the effective date of the consent order as soon it is signed by all parties. If there are any questions, please do not hesitate to call. Thanks, Rob EID294984
