Below are the emails I sent to Shelia on Thurs. identifying what information and sampling information I would request;
however, | read the EPA report by Mark Styar(sp?) yesterday and | think we should ask for all the ['1 through [-14?
chemical compounds he found in the Cape Fear from the Chemours manufacturing line, outfall 001 and outfall 002.

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.
irl
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 [hemours
tenants Kuraray America and DuPont.
[hemouru shall identify all sumps, quench baths, orstorage tanks that discharge wastewaters to the
WVVTP or Outfall 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 or storage 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 by Mei Sun et al.

Chemical characterization testing from each tenant can be performed at a single point of discharge to
theVVVVTP if all wastewaters are combined prior to discharge tothe \NVVTP. If several lines discharge
from each tenant facility tothe VVVVTP, separate chemical characterization tests shall be performed.
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 tothe 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
OU1and the discharge Outfa||OO2.
