Re: Renewal Application
NPDES Permit NC0000752
WestRock Kraft Paper— Roanoke Rapids Mill
Halifax/Northampton County
Dear Ms.Thetford,
The purpose of this correspondence is to request renewal of NPDES Permit NC0000752 for WestRock
Kraft Paper— Roanoke Rapids Mill located in Roanoke Rapids, NC. Enclosed you will find one original
and two copies of our renewal application and all supporting documentation.
During our 2016 renewal we discussed with your agency the possibility of changing the requirement for
sampling Upstream and Downstream locations at a frequency of three times per week during the months
of June through September to once weekly as we do for the other times of the year. We were informed
that the draft permit was already out for notice and any changes would require the process to start over.
We were asked to submit this request at the next permit renewal. We would like to formally request
consideration by the agency to change this requirement to once weekly sampling throughout the year.
Statistical analysis of the Upstream and Downstream data show no significant differences in the data as a
result of gathering three weekly data points versus gathering only one weekly data point.
There have been no significant changes to the wastewater treatment system since our last renewal.
A Transfer of Ownership/Permit Modification was issued on October 25, 2019 to reflect the change in
ownership of the facility from KapStone Kraft Paper, LLC to WestRock Kraft Paper, LLC.
If there are any questions or if there is a need for additional information please contact Chris Williams at
252-533-6237 or by email at chris.m.williams(a)westrock.com.

PROJECT NARRATIVE
Date: August 19, 2021
Client: AECOM(UR002)
Project: Roanoke Rapids-NPDES
Lab ID: CE10551
Overview
Environmental Conservation Laboratories, Inc. (ENCO)analyzed all submitted samples in accordance with the methods
referenced in the laboratory report. Any particular difficulties encountered during sample handling by ENCO are discussed in
the QC Remarks section below.
Quality Control Samples
The 624.1 LCS exhibited a low bias for Acrolein; however this analyte was detected in the CRL standard, verifying instrument
sensitivity. The LCS exhibited a high bias for 1,1,1-Trichloroethane, 1,2-Dichloroethane, Bromodichloromethane, Carbon
tetrachloride, and Chloroform; however,these analytes were not detected in the associated samples. The spike recoveries
for 1,1,1-Trichloroethane, 1,2-Dichloroethane,Acrolein, Bromodichloromethane, Carbon tetrachloride, Chloroform, and
trans-1,2-Dichloroethene were outside control limits for the MS and MSD samples; however, these analytes were not
detected in the associated sample.
The 625.1 Continuing Calibration Verification (CCV)exhibited a high bias for Benzidine, Benzo(g,h,i)perylene,
Dibenzo(a,h)anthracene, Hexachlorobutadiene, and Indeno(1,2,3-cd)pyrene; however,these analytes were not detected in
the associated sample. The CCV exhibited a high bias for Benzo(g,h,i)perylene and Dibenzo(a,h)anthracene, any reported
result should be considered estimated.The CCV exhibited a low bias for Bis(2-chloroisopropyl)ether, any reported result
should be considered a minimum estimate. The LCS exhibited a low bias for Benzidine and Bis(2-chloroisopropyl)ether; any
reported result should be considered a minimum estimate.
The 608.3 spike recovery for Endrin aldehyde was outside control limits for the MS and MSD samples.The QC batches were
approved based on acceptable LCS recovery of this analyte.
The spike recoveries for Iron and Uranium were outside control limits for the MS and MSD samples.The QC batches were
approved based on acceptable LCS recovery of these elements.
The spike recoveries for Ammonia, Cyanide, Fluoride, Nitrate, Phosphorus, Sulfate, and Sulfide were outside control limits for
the MS and/or MSD samples, the precision between duplicate spikes of Ammonia and Fluoride exceeded acceptance
criteria. The QC batches were approved based on acceptable LCS recovery of these analytes.
Quality Control Remarks
The 624.1 surrogate spike recovery of 4-Bromofluorobenzene was outside of acceptance criteria. The samples were
approved based on the recoveries of other surrogate standards.
Other Comments
The analytical data presented in this report are consistent with the methods as referenced in the analytical report. Any
exceptions or deviations are noted in the QC remarks section of this narrative or in the Flags/Notes and Definitions section of
the report.

FLAGS/NOTES AND DEFINITIONS
B The analyte was detected in the associated method blank.
D The sample was analyzed at dilution.
] The reported value is between the laboratory method detection limit(MDL)and the laboratory method
reporting limit(MRL),adjusted for actual sample preparation data and moisture content,where applicable.
U The analyte was analyzed for but not detected to the level shown,adjusted for actual sample preparation
data and moisture content,where applicable.
E The concentration indicated for this analyte is an estimated value above the calibration range of the
instrument.This value is considered an estimate.
MRL Method Reporting Limit.The MRL is roughly equivalent to the practical quantitation limit(PQL)and is
based on the low point of the calibration curve,when applicable,sample preparation factor,dilution
factor,and, in the case of soil samples, moisture content.
PQL PQL: Practical Quantitation Limit. The PQL presented is the laboratory MRL.
N The analysis indicates the presence of an analyte for which there is presumptive evidence(85%or greater
confidence)to make a"tentative identification".
P Greater than 25%concentration difference was observed between the primary and secondary GC column.
The lower concentration is reported.
[CALC] Calculated analyte- MDL/MRL reported to the highest reporting limit of the component analyses.
A-07 Analyte biased low in LCS but detected in the reporting limit standard.Since the analyte in the associated
sample was not detected,there is no impact on data quality.
J-04 Result may be biased high. Associated calibration verification standard exceeded the upper control limit.
3-05 Result may be biased low. Associated calibration verification standard did not meet the minimum control
limit.
J-06 The associated laboratory control sample exhibited low bias;the reported result should be considered to
be a minimum estimate.
QL-02 The associated laboratory control sample exhibited high bias; since the result is ND,there is no impact.
QM-07 The spike recovery was outside acceptance limits for the MS and/or MSD. The batch was accepted based
on acceptable LCS recovery.
QM-11 Precision between duplicate matrix spikes of the same sample was outside acceptance limits.
QM-16 Matrix spike recovery could not be calculated due to high concentration of analyte in source sample.
QS-03 Surrogate recovery outside acceptance limits
QV-01 The associated continuing calibration verification standard exhibited high bias;since the result is ND,there
is no impact.

Client: Enco Laboratories Laboratory Job ID:410-48227-1
Project/Site: CE10551
Analytical test results meet all requirements of the associated regulatory program (e.g., NELAC (TNI), DoD,
and ISO 17025) unless otherwise noted under the individual analysis. Data qualifiers are applied to note
exceptions. Noncompliant quality control (QC) is further explained in narrative comments.
• QC results that exceed the upper limits and are associated with non-detect samples are qualified but further
narration is not required since the bias is high and does not change a non-detect result. Further narration is
also not required with QC blank detection when the associated sample concentration is non-detect or more
than ten times the level in the blank.
• Matrix QC may not be reported if insufficient sample or site-specific QC samples were not submitted. In these
situations, to demonstrate precision and accuracy at a batch level, a LCS/LCSD is performed, unless otherwise
specified in the method.
Surrogate and/or isotope dilution analyte recoveries (if applicable)which are outside of the QC window are
confirmed unless attributed to a dilution or otherwise noted in the narrative.
Regulated compliance samples (e.g. SDWA, NPDES) must comply with the associated agency
requirements/permits.
Measurement uncertainty values, as applicable, are available upon request.
Test results relate only to the sample tested. Clients should be aware that a critical step in a chemical or
microbiological analysis is the collection of the sample. Unless the sample analyzed is truly representative of
the bulk of material involved, the test results will be meaningless. If you have questions regarding the proper
techniques of collecting samples, please contact us. We cannot be held responsible for sample integrity,
however, unless sampling has been performed by a member of our staff. Times are local to the area of activity.
Parameters listed in the 40 CFR Part 136 Table II as"analyze immediately"and tested in the laboratory are not
performed within 15 minutes of collection.
This report shall not be reproduced except in full, without the written approval of the laboratory.
WARRANTY AND LIMITS OF LIABILITY- In accepting analytical work, we warrant the accuracy of test results
for the sample as submitted. The foregoing express warranty is exclusive and is given in lieu of all other
warranties, expressed or implied, except as otherwise agreed. We disclaim any other warranties, expressed or
implied, including a warranty of fitness for particular purpose and warranty of merchantability. In no event shall
Eurofins Lancaster Laboratories Environmental, LLC be liable for indirect, special, consequential, or incidental
damages including, but not limited to, damages for loss of profit or goodwill regardless of(A)the negligence
(either sole or concurrent) of Eurofins Lancaster Laboratories Environmental and (B)whether Eurofins
Lancaster Laboratories Environmental has been informed of the possibility of such damages. We accept no
legal responsibility for the purposes for which the client uses the test results. Except as otherwise agreed, no
purchase order or other order for work shall be accepted by Eurofins Lancaster Laboratories Environmental
which includes any conditions that vary from the Standard Terms and Conditions, and Eurofins Lancaster
Laboratories Environmental hereby objects to any conflicting terms contained in any acceptance or order
submitted by client.

PROJECT NARRATIVE
Date: August 19, 2021
Client: AECOM (UR002)
Project: Roanoke Rapids-NPDES
Lab ID: CE10905
Overview
Environmental Conservation Laboratories, Inc. (ENCO)analyzed all submitted samples in accordance with the methods
referenced in the laboratory report. Any particular difficulties encountered during sample handling by ENCO are discussed in
the QC Remarks section below.
Quality Control Samples
The 624.1 LCS exhibited a low bias for Acrolein; however this analyte was detected in the CRL standard,verifying instrument
sensitivity. The spike recovery for Acrolein was outside control limits for the MS and MSD samples; however, this analyte was
not detected in the associated sample.
The 625.1 Continuing Calibration Verification (CCV)exhibited a high bias for Benzidine, Benzo(g,h,i)perylene,
Dibenzo(a,h)anthracene, Hexachlorobutadiene, and Indeno(1,2,3-cd)pyrene; however,these analytes were not detected in
the associated sample. The CCV exhibited a high bias for Benzo(g,h,i)perylene and Dibenzo(a,h)anthracene, any reported
result should be considered estimated. The CCV exhibited a low bias for Bis(2-chloroisopropyl)ether, any reported result
should be considered a minimum estimate.The LCS exhibited a low bias for Benzidine and Bis(2-chloroisopropyl)ether; any
reported result should be considered a minimum estimate.
The 608.3 spike recovery for Endrin aldehyde was outside control limits for the MS and MSD samples. The QC batches were
approved based on acceptable LCS recovery of this analyte.
The spike recoveries for Iron and Uranium were outside control limits for the MS and MSD samples. The QC batches were
approved based on acceptable LCS recovery of these elements.
The spike recoveries for Ammonia, Cyanide, Fluoride, Nitrate, Phosphorus, Sulfate, and Sulfide were outside control limits for
the MS and/or MSD samples, the precision between duplicate spikes of Ammonia and Fluoride exceeded acceptance
criteria. The QC batches were approved based on acceptable LCS recovery of these analytes.

FLAGS/NOTES AND DEFINITIONS
B The analyte was detected in the associated method blank.
D The sample was analyzed at dilution.
] The reported value is between the laboratory method detection limit(MDL)and the laboratory method
reporting limit(MRL),adjusted for actual sample preparation data and moisture content,where applicable.
U The analyte was analyzed for but not detected to the level shown,adjusted for actual sample preparation
data and moisture content,where applicable.
E The concentration indicated for this analyte is an estimated value above the calibration range of the
instrument.This value is considered an estimate.
MRL Method Reporting Limit.The MRL is roughly equivalent to the practical quantitation limit(PQL)and is
based on the low point of the calibration curve,when applicable,sample preparation factor,dilution
factor,and,in the case of soil samples, moisture content.
PQL PQL: Practical Quantitation Limit. The PQL presented is the laboratory MRL.
N The analysis indicates the presence of an analyte for which there is presumptive evidence(85%or greater
confidence)to make a"tentative identification".
P Greater than 25%concentration difference was observed between the primary and secondary GC column.
The lower concentration is reported.
[CALC] Calculated analyte-MDL/MRL reported to the highest reporting limit of the component analyses.
A-07 Analyte biased low in LCS but detected in the reporting limit standard.Since the analyte in the associated
sample was not detected,there is no impact on data quality.
3-04 Result may be biased high. Associated calibration verification standard exceeded the upper control limit.
3-05 Result may be biased low. Associated calibration verification standard did not meet the minimum control
limit.
3-06 The associated laboratory control sample exhibited low bias;the reported result should be considered to
be a minimum estimate.
QM-07 The spike recovery was outside acceptance limits for the MS and/or MSD. The batch was accepted based
on acceptable LCS recovery.
QM-11 Precision between duplicate matrix spikes of the same sample was outside acceptance limits.
QM-16 Matrix spike recovery could not be calculated due to high concentration of analyte in source sample.
QV-01 The associated continuing calibration verification standard exhibited high bias;since the result is ND,there
is no impact.

Project/Site:CE10905
Analytical test results meet all requirements of the associated regulatory program (e.g., NELAC (TNI), DoD,
and ISO 17025) unless otherwise noted under the individual analysis. Data qualifiers are applied to note
exceptions. Noncompliant quality control (QC) is further explained in narrative comments.
• QC results that exceed the upper limits and are associated with non-detect samples are qualified but further
narration is not required since the bias is high and does not change a non-detect result. Further narration is
also not required with QC blank detection when the associated sample concentration is non-detect or more
than ten times the level in the blank.
• Matrix QC may not be reported if insufficient sample or site-specific QC samples were not submitted. In these
situations, to demonstrate precision and accuracy at a batch level, a LCS/LCSD is performed, unless otherwise
specified in the method.
• Surrogate and/or isotope dilution analyte recoveries (if applicable)which are outside of the QC window are
confirmed unless attributed to a dilution or otherwise noted in the narrative.
Regulated compliance samples (e.g. SDWA, NPDES) must comply with the associated agency
requirements/permits.
Measurement uncertainty values, as applicable, are available upon request.
Test results relate only to the sample tested. Clients should be aware that a critical step in a chemical or
microbiological analysis is the collection of the sample. Unless the sample analyzed is truly representative of
the bulk of material involved, the test results will be meaningless. If you have questions regarding the proper
techniques of collecting samples, please contact us. We cannot be held responsible for sample integrity,
however, unless sampling has been performed by a member of our staff. Times are local to the area of activity.
Parameters listed in the 40 CFR Part 136 Table II as "analyze immediately" and tested in the laboratory are not
performed within 15 minutes of collection.
This report shall not be reproduced except in full, without the written approval of the laboratory.
WARRANTY AND LIMITS OF LIABILITY- In accepting analytical work, we warrant the accuracy of test results
for the sample as submitted. The foregoing express warranty is exclusive and is given in lieu of all other
warranties, expressed or implied, except as otherwise agreed. We disclaim any other warranties, expressed or
implied, including a warranty of fitness for particular purpose and warranty of merchantability. In no event shall
Eurofins Lancaster Laboratories Environmental, LLC be liable for indirect, special, consequential, or incidental
damages including, but not limited to, damages for loss of profit or goodwill regardless of(A) the negligence
(either sole or concurrent) of Eurofins Lancaster Laboratories Environmental and (B)whether Eurofins
Lancaster Laboratories Environmental has been informed of the possibility of such damages. We accept no
legal responsibility for the purposes for which the client uses the test results. Except as otherwise agreed, no
purchase order or other order for work shall be accepted by Eurofins Lancaster Laboratories Environmental
which includes any conditions that vary from the Standard Terms and Conditions, and Eurofins Lancaster
Laboratories Environmental hereby objects to any conflicting terms contained in any acceptance or order
