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. W e will send this info to Rob soon. APFO Isotherm Report Format 1. Objective: to present APFO isotherm data and the methods by whiGh 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 ! F T Roger J Zipfel i J 11/05/2001 03:45 PM \ To: Ron J Buchanan/AE/DuPont@DuPont cc: Subject Mulit Media Consent Order APFO 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 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 3D days of the effective date of the Consent Order. Summary Requirement Tasks Building dimension Confirm existing data are parameters that have a complete and accurate significant impact on air dispersion Permitted allowable Confirm existing data are emission rates, acutal complete and accurate emissions 2000, stack parameters Phase of APFO at Stack Determine mass fraction Conditons particles and mass fraction vapor for each stack emitting APFO Particle Characterization Determine appropriate particle size classes for modeling based on experimental data collected by Zipfel in 1936 Lead Responsibility Mulrooney Mulrooney Zipfel Mulrooney Mulrooney Estimate particle density Particle Scavaging Coefficient Develop technically sound basis for the use of the scavaging coefficients in the ISC users Guidance which are based on particle size. Vapor Scavaging Develop technically Coefficient sound estimate (and document methodology) for the vapor scavaging coefficient of APFO as a function of droplet size Phase Diagram of APFO Develop phase diagram for the range of operating conditions, include critical properties, and phase transition temperature ranges Grise Grise Grise Other Responsibility Shoop, Fu, Zipfel Shoop, F u , Zipfel Grise, Fu, Mulrooney Zipfel Zipfel Mulrooney, Zarzecki Others in DuET JAW003655 EID595784  * iiiss a .v ii APFO in water information Report, with references, the soluability and Kraffl Point of APFO in aqueous solutions and measured pK value.

Please get all the data to me and I will work with our legal representation to develop the communication package(s) that we send. I will 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 JW0O3656 EXD595785
