A Notice of Violation/Intent to Issue Civil Penalty is being issued for the noted violation of North Carolina General
Statute (G.S.) 143-215.1 and the facility's NPDES WW Permit. Pursuant to G.S. 143-215.6A, a civil penalty of
not more than twenty-five thousand dollars ($25,000.00) may be assessed against any person who violates or
fails to act in accordance with the terms, conditions, or requirements of any permit issued pursuant to G.S.
143-215.1.

If you wish to provide additional information regarding the noted violation, request technical assistance, or
discuss overall compliance please respond in writing within ten (10) business days after receipt of this Notice. A
review of your response will be considered along with any information provided on the submitted Monitoring
Report(s). You will then be notified of any civil penalties that may be assessed regarding the violations. If no
response is received in this Office within the 10-day period, a civil penalty assessment may be
prepared.
Remedial actions should have already been taken to correct this problem and prevent further occurrences in the
future. The Division of Water Resources may pursue enforcement action for this and any additional violations of
State law. If the violations are of a continuing nature, not related to operation and/or maintenance problems,
and you anticipate remedial construction activities, then you may wish to consider applying for a Special Order by
Consent.
Reminder: Pursuant to Permit Condition 6 in Section E, the Permittee is required to verbally notify the Regional
Office as soon as possible, not to exceed 24 hours, from first knowledge of any non-compliance at
the facility including limit violations, bypasses of, or failure of a treatment unit. A written report may
be required within 5 days if directed by Division staff. Prior notice should be given for anticipated or
potential problems due to planned maintenance activities, taking units off-line, etc.
If you have any questions concerning this matter or to apply for an SOC, please contact Cheng Zhang of the
Raleigh Regional Office at 919-791-4200.
Sincerely,

Wednesday, December 26, 2018.
Unless otherwise noted in an attached project narrative, all samples were received in
acceptable condition and processed in accordance with the referenced methods/procedures.
Results for these procedures apply only to the samples as submitted.
RECEIVEDI ENRUl!'
The analytical results contained in this report are in compliance with NELAC standards, except
as noted in the project narrative if applicable. This report shall not be reproduced except in
full, without the written approval of the Laboratory.
This report contains only those analyses performed by Environmental Conservation
Laboratories. Unless otherwise noted, all analyses were performed at ENCO Cary. Data from

Overview
This report is an amendment to the original report dated 09 January 2019 for this work order. This report was revised, at the
client's request, to verify the reported concentration of Nickel.
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
No Comments
Quality Control Remarks

Other Comments
At the client's request, the sample was reprepped and reanalyzed for Nickel. The result of the reanalysis is ND, and it was
determined that the original result may have been high biased due to possible carry-over from the sample analyzed
immediately prior to this sample. Both results are included in this report.
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.
7 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.
7-01 Result may be biased high due to positive results in the associated method blank.
QM-07 The spike recovery was outside acceptance limits for the MS and/or MSD. The batch was accepted based
on acceptable LCS recovery.
QR-04 Duplicate precision outside acceptance limits due to low analyte concentration.
