John and I plan to assemble all Isotherm data we have, plot out the isotherms on excel graphs, and then forward the compiled data/charts to Rob. Also. the conditions under which the tests were run will be included (ie. starting concentrations, temperature, test type-shaker flasks.etc, duration, analytical technique). Below is the outline of a brief activated carbon isotherm report John Wilkens and I developed. We will send this info to Rob soon. APFO Isotherm Report Format 1. Objective: to present APFO isotherm data and the methods by which it was generated 2. Materials analyzed (sorptive materials and waters treated) 3. Laboratory methods, including analytical 4. Results (descriptive text, graphs, spreadsheets of data) Thanks again. ....Ron Roger J Zipfel Roger J Zipfel 11/05/2001 03:45 PM To: cc: Subject Ron J Buchanan/AE/DuPont@DuPorrt Mulit Media Consent Order APPO data requirements Ron, I have adsorption data for C-8 on "trade" carbon done by Calgon carbon. It gave a isotherm at 0.224. This led Calgon to give an estimated adsorption efficiency of 0.15 in practical application. Results to date seem to give an adsorption coefficient in the field in the range of 0.15-0.2. This latter range is only an estimate done by myself on very rough data to see if I was close to design carbon useage levels. I have not done more definitive data, and probably will not, as need is not there from my point of view.

This order, as many of you know, will require us to submit a tot of data concerning APPO and our emissions of APPO to the state agencies. To make sure that we all understand our role in getting these data put together and submitting It to Ihe State in the time slated in the order, a lot of coordination needs to be in place. Though the final wording of the order isnt 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. Summary Requirement Building dimension parameters that have a significant impact on air dispersion Permitted allowable emission rates, aortal emissions 2000. stack parameters Phase of APFO at Stack Conditons Particle Characterization Tasks Confirm existing data are complete and accurate Confirm existing data are complete and accurate Determine mass fraction particles and mass fraction vapor for each stack emitting APFO Determine appropriate particle size classes for modeling based on experimental data collected by Zipfel in 1996 Particle Scavaging Coefficient Vapor Scavaging Coefficient Phase Diagram of APFO Estimate particle density Develop technically sound basis for the use of the scavaging coefficients in the ISC users Guidance which are based on particle size.

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 JAW003656 EID595785
