RE: . Town of Ramseur WWTP NCDEQ/DWR/NpDtS
NPDES Permit Renewal-Chemical Addendum
Permit#0026565
Dear Mr.Montebello:
As a supplement to the Ramseur Wastewater Treatment Plant NPDES Application Package that is currently under review,the
Town of Ramseur is submitting additional information per Session Law 2018-5,Senate Bill 99,Section 13.1(r). At the
request of the Division of Environmental Quality(DEQ),the Town conducted additional WWTP influent sampling in July,
August,and September 2019 for 1,4-Dioxane.The analysis was done in accordance with EPA Method 624.1,which is a
certified method in 40 CFR Part 136.Accordingly,the Town is providing a Chemical Addendum to the NPDES Application
for the 1,4 Dioxane influent sampling results.
Additionally,at the request of DEQ,the Town performed WWTP influent sampling for a series of PFOA/PFAS analytes in
July,August,and September 2019.This sampling is not certified by the Town as there is not a 40 CFR Part 136 certified
analysis method for the analytes.This data was previously provided to DEQ following the three sampling events in 2019.
Although this data is not being certified by the Town and was already provided to DEQ,we are providing a summary of the
results as an attachment to this for clarity.
The following attachments are being provided as a supplement to the Ramseur WWTP NPDES Permit Application.
Attachment 1: Chemical Addendum to NPDES Application
Attachment 2: Lab Reports from 1,4 Dioxane Sampling Results
Attachment 3: Uncertified Emerging Compound Sampling Data Summary
Please let us know if you have any questions on the information provided.

Enthalpy Analytical Narrative Summary
Company Suez Water Ramseur
Job# 0919-708 PFAS—Legacy 24+Gen-X
Client Project# n/a
Custody Hunter Allen of Enthalpy Analytical Wilmington received the sample on
09/08/19 on ice at 2.6°C.Braidy May of Enthalpy Analytical Wilmington
observed the samples were in good condition on 09/09/19.
Prior to,during,and after analysis,the sample was stored in the laboratory
with access only by authorized personnel of Enthalpy Analytical, LLC.
Analysis The sample was analyzed by isotope dilution method for PFAS using
Waters Acquity UPLC equipped with Xevo TQ MS (LC/MS/MS"Kili").
For aqueous samples, 250mL aliquot was weighed and spiked with
Extraction Standard (ES). The sample was then mixed well and
centrifuged.
Cleanup procedures were performed on the supernatant and then
extracted via SPE. Each final sample extract was transferred to an
autosampler vial and spiked with 4004 of Injection Standard(IS),prior
to analysis.
Calibration The analytes and labeled standards in the initial calibration exhibited
RSDs less than 50%with exception of the following:
M8FOSA and d3-N-MeFOSAA
All analytes passed the R2 coefficient correlation criteria. Per DoD QSM
5.3 Table B-15, the ICAL is acceptable for all analytes since R2 met
criteria. All analytes will be reported.
The ICV and continuing calibration (concal) injections met the ±30%
recovery criteria and ±50% ES recovery criteria for all analytes of
interest.
QC Notes The QC injections of the initial extraction did not meet method criteria
requiring re-extraction of samples. The QC of re-extracted samples met
the +50% criteria for ES recoveries with the exception of analyte
M2PFTeDA, which fell below the lower limit in the method blank.
However, this compound was recovered within limits for the OPR for
both native and labeled criteria. Therefore, the data are considered
acceptable and no impact on sample data.
No analytes were detected above the LOD (MDL) in the method blank.
The samples were extracted within the 14-day from collection holding
time (initial extraction—Sept 17 and re-extraction—Sept 20). Extracts

Enthalpy Analytical Narrative Summary
(continued)
QC Notes were analyzed within the 28-days from extraction to analysis holding time
(continued) required by the method.
Reporting Notes Results from the re-extraction are included in this report.
Analyte PFPeA had elevated values that were not consistent with past
patterns. After investigation, it was concluded the values were valid and
are reported.
Some analytes in the samples fell outside the limits for ES recoveries.
Although the cause was undetermined, it is theorized to be matrix effects.
Based on the native results in the OPR meeting criteria,the out-of-range
ES recoveries have no impact on the accuracy of the target analyte
(native)compounds. Therefore,the data are considered acceptable.
These analyses met the requirements of the TNI Standard. Any
deviations from the requirements of the reference method or TNI
Standard have been stated above.
The results presented in this report are representative of the samples as
provided to the laboratory.
The samples, calibrations and standards for the data presented in this
report were analyzed at 2714 Exchange Drive, Wilmington,NC 28405.
