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 [hemoun
tenants Kuraray America and DuPont.
Chemours shall identify all sumps, quench baths, or storage 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 orsump 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, TS5, [-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 to the \NVVTP. If several lines discharge
from each tenant facility tothe WVVTP, 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
OO1and the discharge OutfaUOOZ
