Here are the responses to Brandon's questions. Are you ok with them? Don't know about the last question.
In reference to The Chemours Company — Fayetteville Works permit renewal application (NCO003573) — I'm wondering if

Also, do you have an expected date of when testing of the sampling done in the Cape Fear River will be available?
We are hoping to have the sampling analysis completed by .....
