Re: Draft Permit NC0003573
To Whom It May Concern,
I appreciate the opportunity to comment on the renewal of the Discharge Permit for the
DuPont Chemical Works in Fayetteville. It is my firm belief that companies that profit
from the use of our most basic and valuable environmental infrastructure, our water and
our air should be accountable for high and responsible standards for this privilege. I also
believe that companies like DuPont should be paying for testing conducted by third
parties administered by North Carolina and they should be investing in technology to
limit and eliminate their need to use the water and air to carry away their waste products.
This technology and its effectiveness should be subject of a high level of public scrutiny.
From the simple to the extremely complex it does not appear that this permit holds
DuPont to high standards. The amount of sediment that is carried into the Cape Fear
River with the discharge water from the DuPont plant should be reduced and the testing
requirement for turbidity should be tightened. There is a growing number of North
Carolina residents who are interested in a healthy Cape Fear River to again support the
wild life in the River and along its banks. North Carolina should require DuPont to
become a partner in this effort by eliminating the sediment they are adding.
The down stream mixing zone of 4500 feet should be completely removed for turbidity
and all other testing. All testing should be done at the point where the discharge enters
the Cape Fear River. I am certain that this would be more reliable and would give both
DuPont and State and Federal regulators a clearer picture of the discharge and of efforts
to reduce dangerous waste product in the discharge water.
PFOA, C8 has been identified by the EPA as a likely cancer causing substance. The
Fayetteville plant is the only plant in the United States currently producing C8. The
permit should include standards and limits on PFOA, C8. The fact sheet that goes along
with this permit states that all the discharge from the PFOA plant is currently treated off
site. This should be a requirement of the discharge permit. There is currently nothing that
would stop DuPont from treating the PFOA discharge on site. If this is done there is no
requirement for DuPont to test for PFOA in their discharge water.
I have other concerns and I have heard concerns from other citizens in the Cape Fear
River watershed. I hope we all have the opportunity to voice our concerns and to learn
more about this discharge permit for one of the most complex and complicated chemical
production facilities in North Carolina through a public hearing. Pleas notify me about a
hearing when one is scheduled.

Thank you for the opportunity to comment on this draft permit. I am pleased that the
Division of Water Quality recognizes the vital role informed citizen involvement has in
developing sound and responsible public policies and decisions.
Sincerely yours,
