Maria - as I have veered into answering a question that includes drinking water - please wait for Jessica to weigh in—1
do not wish to misspeak !
2) This question mixes some topics and some program areas - so - I hope to straighten it out the issues!
There are established drinking water health advisories for the combined occurrence of PFOS and PFOA
(Safe Drinking Water Act program) (0.07 uu/U. There is no federal level established hzrGenX. As noted
previously, the U8 EPA (under the Safe drinking Water Act) isthe sole agency responsible for
establishing drinking water standards. I can't speak directly to the question of whether the US EPA will
take additional actions with respect to regulation of PFOS and PFOA in drinking water.
There is an established Interim Maximum Allowable Concentration (IMAC) for PFOA (2 ug/L) in
0ruundvvaters of the State. (ref: lSA NCA[ 02L). This is a health protective state regulation and dues not
have afederal counterpart. There are currently 58 |MA[s established under the OJLrule. These are
currently under review by the Department at this time. As directed by rule, where revised scientifically
peer reviewed information is available for consideration in modification of groundwater standard, that
information is used to advise the Environmental Management Commission on allowable concentrations
that may affect the use ufgroundwater asasource ofdrinking water.

Hi Marla,
Thanks for taking mycall amoment ago. Amlmentioned, lhad ucouple follow-up questions that lwasn't sure
about the answers on:
1) It sounded like GenX was not part of the previous permitting process for Chemours' FayettevilleoJant.Isthot
correct?
2)lknow the existing PF{)Astandard is only for groundwater,but vvediscussed ongoingrexievv for potential
tub/re standards. Are those reviews for standards for both ground vvn1er and drinking water? Or solely for
ground water?
Thanks for your help!
Adam
