Re: DuPont Kinston NPDES Permit Renewal Application Addendum
NPDES Permit No. NC0003760
Dear Mr.Dowden,
The DuPont Kinston Site currently operates under National Pollutant Discharge Elimination
System(NPDES)Permit No.NC0003760 issued by the Division of Water Resources(DWR)on
December 12,2018 and expiring on March 31,2022. Pursuant to Title 15A, Subchapter 02H of
the North Carolina Administrative Code, applications for permit renewals should be submitted at
least 180 days prior to expiration of a permit. DuPont Kinston submitted the initial NPDES
permit application package on October 1, 2021.DuPont Kinston is submitting this application
addendum to provide sample results for Outfalls 002, 005, and 006. Please find enclosed a
revised Form 2C. DuPont Kinston will submit sample results for Outfalls 008, 009, 010, 011, and
012 in a second application addendum by the end of March 2022.
If there any questions,please feel free to contact me at(252) 559-7043 or Shelby Arellano at

Section 6.2—Schedule of Compliance
The current NPDES permit includes future numerical metals limits for Outfalls 002 and 003 with
an effective date of April 1, 2022. DuPont Kinston developed a Corrective Action Plan(CAP)
that summarizes actions to be taken to achieve compliance for the new total zinc and total lead
limits at Outfall 002 and the new total copper,total lead,total silver,and total zinc limits at
Outfall 003.
Outfall 002
DuPont Kinston is requesting to move the currently permitted Outfall 002 and to add 2 new
outfalls, Outfalls 011 and 012. The new outfalls will capture stormwater runoff and groundwater
discharges from the C&D and Ash landfills. The revised outfall designations will provide more
representative sample data. Additional time is required to further investigate metals
concentrations from the discharges of impacted groundwater. Due to drought conditions,the Site
has been unable to sample at Outfalls 011 and 012.
Additional considerations need to be given to the CAP and the schedule of compliance for
Outfall 002 based on the revised outfall designations and discharge information. As such,
DuPont Kinston is requesting a two-year extension to the effective date of the new metal limits
to Outfall 002.A revised CAP will be submitted in a second application addendum by the end of
March 2022 with the sample results for Outfalls 011 and 012.
Outfall 003
DuPont initially proposed relocating the monitoring point for Outfall 003 as part of the CAP.
However,D&R activities from 2017 to 2021 have completely removed the sources of
stormwater from industrial activity. In addition to the D&R work, all steam condensate lines
have been removed or rerouted. The only remaining discharges from Outfall 003 are stormwater
runoff from an administrative building and the accompanying parking lot,uncontaminated air
conditioning condensate, and stormwater runoff from D&R areas where significant materials no
longer remain.Although Outfall 003 is currently subject to a compliance schedule,the
substantial alterations associated with discharges to this outfall justify removal of this outfall
from the permit. Sample data results clearly demonstrate the decrease in metal concentrations.
DuPont Kinston has showed continued compliance with the new metal limits over the past two
years.

Section 7.1 — Requested Waivers
1. DuPont is requesting that DWR waive composite sampling requirements for the wastewater
outfalls composed of only stormwater runoff and impacted groundwater(Outfalls 005, 006,
008, 009, 010, 011, and 012). The use of an automatic sampler is impractical as sampling
locations are in heavily wooded areas without access to electricity. Per guidance provided on
page 2C-6 of Form 2C Instructions, DuPont Kinston collected 4 grab samples for Outfalls
005 and 006, and the samples were composited in the lab. Sample data provided in the
application for the revised Outfall 002 location was collected as constant time/constant
volume samples per the requirements for Outfall 002 in the current permit.
2. DuPont is requesting that DWR waive the requirement to test for flow rate for the wastewater
outfalls composed of only stormwater runoff and impacted groundwater(Outfalls 005, 006,
008, 009, 010, 011, and 012). Discharges from these outfalls are intermittent and heavily
dependent on rain events. Although these outfalls are permitted as wastewater outfalls,
sampling of these outfalls will need to be managed similarly to stormwater sampling. Flow is
not a required monitoring parameter for the stormwater outfalls in the Site's current NPDES
permit.
3. DuPont Kinston is requesting that DWR waive the requirement to test for summer
q g q
temperatures. Temperature is not a required monitoring parameter in the current permit for
Outfalls 005 and 006, and Outfall 002 is at a revised location that has not been monitored for
temperature in recent years. Winter temperatures are the only available temperature data at
this time for Outfalls 002, 005, 006, 008, 009, 010, 011, and 012.
Additional Information
The outfalls discharging impacted groundwater are being analyzed in accordance with Form 2C
for potential constituents of concern identified in the RCRA investigations. In addition to the
sample results provided in Form 2C, Table 1 provides sample results for 1,4-dioxane at Outfalls
002, 005, and 006.
