In accordance with your completed Air h Permit ication for minor modification of a Title V
permit received on May 20,2011 we are foot�rd' erewith Quality Permit No. 03735T37 to E.I. du Pont de
Nemours and Company, Duart Township, B1aCounty, North Carolina authorizing the construction and
operation of the emission source(s) and associateir pollution control device(s) specified herein. Additionally,
any emissions activities determined from Air Quality Permit Application as being insignificant per 15A North
Carolina Administrative Code 2Q .0503 hav been listed for informational purposes. Please note the requirements
for the annual compliance certificationii�.conhed in General Condition P in Section 3. The current owner is
responsible for submittipg a compliance ce�"ication for the entire year regardless of who owned the facility
during the year. ^
As the designates sponsible official it is your responsibility to review, understand, and abide by all of
the terms and conditionT of the attached permit. It is also your responsibility to ensure that any person who
operates annmission so d associated air pollution control device subject to any term or condition of the
attach rmit reviews, un rstands, and abides by the condition(s) of the attached permit that are applicable to
that cula emission sorce.
