What's the status of the testing -- what's been done so far? What's coming up this week and later?
When might we expect results? And, can you tell me, specifically, when CFPUA's ASR well is
being tested?
Sent the sampling schedule press release.
Can DEQ confirm that Chemours has, in fact, been operating the process that results in GenX as
a byproduct throughout the testing period? We've had a number of questions from folks
wondering about this since the company said it was an intermittent process and it would be great
to put that to bed.
Chemours has indicated. the process (the vinyl ether process) that results in GenX as a byproduct
,,) rd
has been ongoing throughout the testing — -1 jsampling process. On Friday, June , DEQ requested.
operating information to show when the process had been in production so we can compare that
information to date to when sampling occurred.
Has DEQ confirmed definitively that Chemours has ceased discharging GenX into the Cape
Fear? When did that actually occur? Does it include the other "novel" compounds? How is
Chemours keeping the wastewater from being discharged? Mike Johnson mentioned something
about needing three tanker trucks a day to handle it. Is that what they're doing? Is that being
hauled off for incineration? If so, where? If not trucks, what is the process? Also, has DEQ
visited to plant to inspect this process?
Chemours has told us it has stopped discharging what's known as GenX into the Cape Fear as of
June 21, 210 17. Our samples, which have been sent to the EPA lab the same one Dr. Knappe
used in his study %N;ill be analyzed for other compounds included in the study report.
Chemours has indicated it is keeping the wastewater from being discharged by usiiw temporary
storage tanks to hold the waste as they are working on final out- of state disposal options.
Chemours made one shipment to an Arkansas commercial incinerator Thursday, June 22'd for a
trial burn.
DEQ has been to the facility to collect wastewater discharge samples but not to conduct an in
depth site inspection. DEQ is working with EPA Toxic Substance Control Act (TSCA) staff to
ualn access to information submitted to EPA that will help the state evaluate all manufacturing
processes and potential chemicals that need to be included in the NPDES permit renewal before
the upcoming site visit.
