Shelia,
Note that PFOS is not believed to be a present (I verified this with Connie) which is why I left it out of the sampling.

Shelia,
Below is my suggestion — I really should work on this for one or two more days and discuss with the permit writer
(Teresa Rodriguez). Also, we are doing a site visit next week and I will understand what is needed much better after the
site visit.
You said nine compounds, I assume you mean all nine PFECAs and PFOA and PFOS (see attached chart).
Chemours shall identify each specific manufacturing process and provide a chemical characterization of what is used in
each process that can result in a wastewater discharge. This shall be done for Chemoumtenants Kuraray America and
DuPont.
Chemours shall identify all sumps, quench baths, or storage tanks that discharge wastewaterstotheVVVVTPorOuda||
002. Chemours shall provide a chemical characterization of each discharge from each sump area. A separate chemical
characterization shall be performed on any wastewaters from quench bath overflows orstorage tank discharges that are
not included in the chemical characterization of each manufacturing process or sump area discharge.
Chemical characterizations from each manufacturing process at Chemours and the sumps (and quench baths and
storage tanks if necessary) shall include analysis for pH, TSS, C-8 (ammonium perfluorooctanoate), COD, TOC,
manufacturing operations -specific organics and metals, and all GenX compounds including the PFECAs discussed in the
report published byMeiSun etal.
Chemical characterization testing fnomeachtenantcanbeperfonmedatasindepointofdischargetodheVVVVTPifaU
wastewaters are combined prior to discharge to theVV\NTP. If several lines discharge from each tenant facility to the
VV\NTP,separate chemical characterization tests shall beperformed.
Aflow schematic of all internal process wastewater streams from all manufacturing units including the tenants shall be
developed and submitted along with the requested information above to DWR as an addendum to the permit renewal
application.
On days Chemours performs chemical characterization testing on its own facility's process wastewaters a similar sample
and test analysis for the parameters listed above shall be performed at internal Outfall 001 and the discharge Outfall
OOJ.
