On February 15, 2007, EPA, Exygen and DuPont met to discuss the December data and the path forward 

proposal provided by Exygen. 

On March 05, 2007, EPA provided DuPont with a Path Forward request. From March 05, 2007 until 

May 1, 2007 DuPont, EPA and Exygen worked to resolve open issues. After resolving issues and 

agreeing on a path forward, Exygen developed a protocol and performed the additional experiments 

requested by EPA on March 05, 2007. 

The final Exygen Analytical Protocol was approved by DuPont May 11, 2007. A Draft Validation Report 

was provided by Exygen and received by DuPont on June 4, 2007. On June 8, 2007, DuPont requested 

raw data from Exygen. The raw data was provided to DuPont on June 8, 2007. After reviewing the data, 

DuPont and Exygen engaged in correspondences via email to resolve some quality issues before moving 

on to the Sample Protocol. Exygen and DuPont agreed on the Sample Protocol on June 19, 2007. The 

Draft report for the Sample Data was sent to DuPont on June 25, 2007. All protocol, correspondences, 

and data were submitted to EPA for review on June 26, 2007. DuPont is waiting for feedback and 

direction for a path forward from EPA. 

Deadlines: On March 23, 2007, a 6th request for extension for the date for which the parties much agree 

on a purification procedure was submitted by DuPont. On March 27, 2007, EPA accepted the DuPont 

request for extension (email correspondence, James Vinch EPA, 03.28.2007 08:52 AM). The new 

deadline to agree on a purification procedure is August 31, 2007.
