Notes:
1. Upstream monitoring shall be at the Permittee s ape Fear Rive Water Intake; downstream shall be at the
boat ramp approximately 4500 feet downstream at Prospect Hall Landing.
As a participant in the Middle Cape Fear River Basin Association, the instream monitoring requirements for
conventional parameters (DO, temperature, and conductivity) as stated above are waived. Should your
membership in the agreement be terminated, you shall notify the Division immediately and the instream
monitoring requirements specified in your permit shall be reinstated.
Influent — influent to the Old Outfall 002 Wastewater Treatment System. Note the Outfall 003 concentration
limitations do not apply to the influent. Influent sampling is required to calculate the HFPO-DA and
PFMOAA percent removal.
Effluent — Outfall 003 (effluent from the Old Outfall 002 Wastewater Treatment System).
2. The temperature of the effluent shall be such as not to cause an increase in the temperature of the receiving
stream of more than 2.8°C and in no case cause the ambient water temperature to exceed 32°C.
3. The existing PQL for Silver is 1.0 µg/L. Therefore, the Division shall consider all effluent Silver values reported
below 1.0 µg/L to be in compliance with the Monthly Average Silver limit.
4. The Permittee shall remove indicator parameters HFPO-DA and PFMOAA at an efficiency of 99% as required
by the Consent Order in order to maximally reduce PFAS loading to the Cape Fear River. The effluent limits
listed above are Technology Based Effluent Limits ("TBELs") calculated to ensure a minimum of 99% removal
efficiency. In addition to complying with these effluent limits the Permittee must demonstrate compliance with
the 99% removal efficiency requirement by calculating monthly removal efficiency for HFPO-DA and
PFMOAA pursuant to condition A. (6.). If the influent HFPO-DA or PFMOAA concentrations to the water
treatment system are equal to or less than 200 ng/L and 500 ng/L, respectively then water treatment system
effluent concentrations of less than the reporting limits (2 ng/L and 5 ng/L respectively) shall be considered as
achieving 99% removal. The Permittee may request revision of the 99% removal efficiency requirement upon
a demonstration that influent concentrations of PFAS have been reduced to such a level that 99% removal is no
longer technically feasible. However, notwithstanding any such revision, Chemours shall continue to operate
the Treatment System at optimal efficiency.
5. Chronic Toxicity (Ceriodaphnia) P/F @ 12.5%; quarterly during February, May, August, November; see
condition A. (2.) of this permit.
6. This is an Annual Average limit, based on a calendar year.
Page 4 of 12
Permit NCO089915
7. After 12 months of sampling the facility can apply for a reduction in sampling if all the sampling results
demonstrate concentrations below detections level. The facility shall be employing the sufficiently sensitive
test methods.
THERE SHALL BE NO DISCHARGE OF FLOATING SOLIDS OR VISIBLE FOAM IN OTHER THAN TRACE AMOUNTS.
The facility shall develop a Dam (collection system) Operation and Maintenance Plan (Plan) to ensure
maximum dry weather flow (— 610 gpm) in the channel is consistently captured and treated. Similar efforts
should be applied at the sumps/dams or other devices that will be used to capture water from the seeps.
The Plan should be provided to the DEQ within 30 days of the permit issuance for review and approval.
Upon approval, the Plan becomes an integral part of the permit.
The facility shall complete and submit EPA Form 2C for this Outfall within 180 days of commencement of
the discharge.
Upon the implementation of the Old Outfall 002 treatment system pursuant to Consent Order
Paragraph 12(e), Chemours shall commence pumping of groundwater from the seven existing Black
Creek Aquifer monitoring wells and conveyance of such groundwater by piping to the Old Outfall
002 treatment system for treatment and discharge. The facility shall notify the DEQ in writing 15
day prior to the commencement of the pumping operation.
A. (2.) CHRONIC TOXICITY PERMIT LIMIT P/F (QUARTERLY) — OUTFALL 003
[15ANCAC 02B.0200]
The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant mortality to
Ceriodaphnia dubia at an effluent concentration of 12.5%.
The permit holder shall perform at a minimum, quarterly monitoring using test procedures outlined in the "North
Carolina Ceriodaphnia Chronic Effluent Bioassay Procedure," (Revised December 2010, or subsequent versions)
or "North Carolina Phase II Chronic Whole Effluent Toxicity Test Procedure" (Revised December 2010, or
subsequent versions). The tests will be performed during the months of February, May, August, and
November. These months signify the first month of each three-month toxicity testing quarter assigned to the
facility. Effluent sampling for this testing must be obtained during representative effluent discharge and shall be
performed at the NPDES permitted final effluent discharge below all treatment processes.
If the test procedure performed as the first test of any single quarter results in a failure or ChV below the
permit limit, then multiple -concentration testing shall be performed at a minimum, in each of the two
following months as described in "North Carolina Phase II Chronic Whole Effluent Toxicity Test
Procedure" (Revised -December 2010, or subsequent versions).
All toxicity testing results required as part of this permit condition will be entered electronically using the
Division's eDMR system for the months in which tests were performed, using the parameter code TGP3B for the
pass/fail results and THP3B for the Chronic Value. Additionally, DWR Form AT-3 (original) is to be sent to the
following address:
North Carolina Division of Water Resources
Water Sciences Section/Aquatic Toxicology Branch
1621 Mail Service Center
Raleigh, NC 27699-1621
Page 5 of 12
Permit NCO089915
Or, results can be sent to the email, ATForms.ATBkncdenr.gov.
Completed Aquatic Toxicity Test Forms shall be filed with the Water Sciences Section no later than 30 days after
the end of the reporting period for which the report is made.
Test data shall be complete, accurate, include all supporting chemical/physical measurements and all
concentration/response data, and be certified by laboratory supervisor and ORC or approved designate signature.
Total residual chlorine of the effluent toxicity sample must be measured and reported if chlorine is employed for
disinfection of the waste stream.
Should there be no discharge of flow from the facility during a month in which toxicity monitoring is required,
the permittee will complete the information located at the top of the aquatic toxicity (AT) test form indicating the
facility name, permit number, pipe number, county, and the month/year of the report with the notation of "No
Flow" in the comment area of the form. The report shall be submitted to the Water Sciences Section at the address
cited above.
Should the permittee fail to monitor during a month in which toxicity monito is required, monitoring will be
required during the following month. Assessment of toxicity compliance is base on the toxicity testing quarter,
which is the three-month time interval that begins on the first day of the month in whi toxicity testing is
required by this permit and continues until the final day of the third month.
Should any test data from this monitoring requirement or tests performed by the North Carolina Division of Water
Resources indicate potential impacts to the receiving s cam, this p t may be re -opened and modified to
include alternate monitoring requirements or limits.
NOTE: Failure to achieve test conditions as sped led in the cite documen , such as minimum control organism
survival, minimum control organism reproduction, and appropriate environmental controls, shall constitute an
invalid test and will require immediate follow-up testing to be completed no later than the last day of the month
following the month of the mitia monitorin .

A. (6.) CALCULATION OF HFPO-DA & PFMOAA REMOVAL/LOADS
a. The Permittee shall calculate monthly removal efficienc for HFPO-DA and PFMOAA as follows:
%Removal =
Inf luent-Ef f luen
Influent
Where:
Influent = monthly average influent concentration
Effluent = monthly average effluent concentration
b. The Permittee shall calculate monthly load for HFPO-DA and PFMOAA as follows:
Monthly Load = C x TMF x 8.34
Where:
C = monthly average concentration for each compound (mg/L)
TMF = Total Monthly Flow of wastewater discharged during the month (MG/month)
8.34 = conversion factor from (mg/L x MG) to pounds
lqmmw
Annual C Load = Sum of the 12 Monthly Loads for each compound for the calendar year
c. The Permittee shall report monthly HFPO-DA and PFMOAA results [% removal (ng/L), and Loading
(pounds/month)] in the discharge monitoring report for each month and shall report each calendar year's
Annual Load (pounds/year) with the December report for that year. Percent removal shall be listed in the
comment section of the eDMR since it has no parameter code.
In addition, calculations shall be submitted electronically with all PFAS data to NPDES Permitting via
email at svc_dec-npdes-ecgncdenr.gov, with the Facility permit number and name in the Subject
heading.
