Subject: Chemours Fayetteville Works CMS request
Joe,
As described in the CMS work plan, the project team for the Chemours Fayetteville Works site recently collected
sampling data from monitoring well LTW-05. This sample was collected to confirm an earlier concentration of 11
pg/L of PFPeA (C-5) that was detected in the well in 2015. Chemours has received the results of this sampling, and
the results indicated a concentration of 2.9 pg/L of PFPeA in the well (the duplicate sample = 3.8 pg/L). The
Parsons field team then returned to the site on Thursday, June 15th to collect several additional samples to confirm -
the earlier results. The team collected samples from monitoring wells LTW-04 and LTW-05, along with an effluent
sample from the site's outfall (we have not received these results as of the time of this note).
A Fayetteville Works site chemist believes that PFPeA (C-5) was potentially discharged in the site's final effluent until
2013 when a process change was installed, and the June 15th sampling will confirm the C-5 compound is no longer
present in the final effluent.
Due to this re -sampling effort, along with the sampling for additional compounds that you requested last week (in an
email to the plant Environmental Manager, Michael Johnson), we are requesting a delay in the completion of the
CMS and associated report as we collect more data. The current schedule (as presented in the work plan) calls for
the submittal of the CMS Report three months after receipt of the final analytical data from the initial sampling. The
project team would like to also include the re-sampling/additional sampling data in the CMS evaluation. Once the
additional sampling has been completed and all of the final analytical data has been received, Chemours will work
with NCDEQ to develop an appropriate revised schedule for completion of the CMS/CMS Report.
Please let me know if you have any questions about our proposed path forward.
Respectfully submitted,
Kevin
