* Regional staff have GPS coordinates for sampling locations. Will send an email with those from the Wilmington area. Mark
please send those for the Fayetteville area.
• Mark Brantley knows we also want a sample from the City of Fayetteville water intake on Monday. Mark appreciate you
making arrangements inadvance.
* Chemours production staff will be onsite Monday July 3rd and production processes will be active, but some of the other
staff will not be at the plant. Arrangements are being made for Mark to get access to outfall 002 for sampling. Test America
will not be open July 4th. Due to their requirement to ice the samples, the samples from July 3rd will be held at the
Fayetteville Regional Office in the lab refrigerator until Weds. July 5th at which time they will be shipped to Test America in
ice. We will include that description in the QAPP and note on the Chain of Custody.
• The sampling process at Chemours outfall 002 does involve using a dipper to collect the sample and then pour it into a
containerduototheaccesspointbeing6'obovothooutfaU.Thedipperis^rinsed^inoutfa||OOIeMluentpriortosamp|ing.
We will include that description inthe DAPP.
* Chemours will pay for the trip blank, high spike and low spike analysis at Test America. Michael Aucoin, Chernours'AECOM
consultant coordinating sampling for Chernours and the analysis for all the samples going to Test America, is talking with
Test America about the subject EPA sample containers containing nitric acid. The sample kits DEQ received from Test
America were not prepped with nitric acid. We will forward the response upon receipt.
* Test America isonly reporting results for GenX HFPOdimeracid.
� Chris Johnson brought up the concept of getting production samples from the site. Michael Johnson will ask his
management. We let Michael know we were going to take the upriver sample and Chris indicated that sample will help us
know what they may be bringing into the plant and help understand the effluent leaving the plant. Chris indicated having
the production samples will help verify we are analyzing for the correct chemicals. Becky know you were going tusee if
the EPA TSCA inspectors could/would take production process samplings. Wanted to give you a heads up about our
conversation.
* 1 will get refinement on DEQ and DHHS contacts for collaboration on future sampling/analysis concepts during our Weds
morning call with DE[l&DHHS.Look forward tothose planning discussions.
* Jamie Kritzer, DEQ Public Affairs, is getting a Communications team meeting set with DEQ/DHHS/EPA contacts.
