Dear Administrator Pruitt:
North Carolina residents need immediate help and long-term certainty about the safety of the water
they drink. I write seeking your urgent action to get us answers and solutions.
When we turn on the tap to get a drink, cook a meal for our family, or run a bath for our children, we
count on that water to be safe. North Carolina must have your help to make sure the water is safe for
millions of our families.
At my direction, the NC Department of Environmental Quality (DEQ) along with the NC Department of
Health and Human Services (DHHS) launched an investigation June 14 into the presence of the
unregulated chemical GenX in the [ape Fear River, the primary source ofdrinking water for Brunswick,
Bladen, New Hanover and Pender counties in North Carolina. This compound entered the river as
wastewater discharge at a Chemours manufacturing facility near Fayetteville. Following requests fnom
my administration, local leaders and area residents, Chemours stopped discharging GenXvvhi|e the state
investigation isunderway.
The good news is that initial results from ongoing rigorous water sampling being conducted by state
scientists shows that levels of GenX in the water supply have decreased dramatically since we succeeded
at getting Chemours to cease its discharge. However, many questions remain about potential health
effects caused by exposure to this and other emerging contaminants, and we know that only your
agency can give regulatory certainty about this contaminant.
The troubling problem ofunregulated, relatively unknown chemicals inthe public water supply b
nationwide and cannot be solved by our state alone. I appreciate the assistance the EPA has provided
thus far to scientists with DEQ and DHHS working on our GenX investigation, but we need the EPA to
move more quickly to finalize its health assessment of GenX and set a maximum contaminant level for it.
These are critical steps that must take place in order for North Carolina to be able to require Chemours
to limit or eliminate discharge ofGenX.
The EPA already has an order in place to control some GenX emissions that should be expanded to hold
Chemoursaccountable for any discharge ofGenX.Aayou may know, EPA concerns that 6enXcould be
toxic led the agency to seek a 2009 consent order limiting Chemours' emissions from GenX production.
However, Chemours has stated publicly that it does not believe this order governs discharge of the same
chemical when it is a byproduct of other chemical processes. I ask that the EPA revisit this consent order
North Carolina and its people rely on the EPA to ensure chemicals are manufactured in a way that
protects our air, our water and our health. Under the U.S. Toxic Substances Control Act (TSCA), the EPA
bears the sole responsibility for regulating the introduction of new chemicals. I urge you to use EPA

authority under the TSCA to evaluate byproducts from other Chemours production lines, including
wastewater discharge.
I also ask that you require companies to submit not just one but multiple health studies covering several
exposure methods when registering chemicals under TSCA. This will increase the public's understanding
of chemical compounds introduced into our waterways. These safeguards are more important than
ever as North Carolina and other states confront the presence of unregulated, emerging contaminants
in our water.
The water, health and welfare of the people of North Carolina require your protection now from
unregulated emerging contaminants like GenX, and I look forward to working with your agency on this
and avariety ofwater quality issues.
I thank you for the support that your agency is providing to North Carolina, and look forward to your
