LABORATORY NAME: Duke Power Company LLC d/b/a Duke Energy Carolinas - Dan
River
NPDES PERMIT #: NC0003468
ADDRESS: Dan River Combined Cycle
864 S. Edgewood Rd.
Eden, NC 27288-3659
CERTIFICATE #: 5153
DATE OF INSPECTION: April 18, 2017
TYPE OF INSPECTION: Field Industrial Maintenance
AUDITOR(S): Tonja Springer
LOCAL PERSON(S) CONTACTED: Dana Newcomb
INTRODUCTION:
This laboratory was inspected by a representative of the North Carolina Wastewater/Groundwater
Laboratory Certification (NC WW/GW LC) program to verify its compliance with the requirements
of 15A NCAC 2H .0800 for the analysis of environmental samples.
GENERAL COMMENTS:
The facility has all the equipment necessary to perform the analyses. The laboratory analyst was
very forthcoming and receptive to implementing the necessary changes in response to Findings
and Recommendations noted during the inspection.
All required Proficiency Testing (PT) samples for the 2017 PT calendar year have not yet been
analyzed. The laboratory is reminded that results must be received by this office directly from the
vendor by September 30, 2017.
Contracted analyses are performed by Pace Analytical Services, LLC — Huntersville, NC
(Certification #12) and Pace Analytical Services, LLC - Field Services NC (Certification #5342)
Current Quality Assurance Policies for Field Laboratories and Approved Procedure documents
for the analysis of the facility's currently certified Field Parameters were provided at the time of
the inspection.
III. FINDINGS, REQUIREMENTS, COMMENTS AND RECOMMENDATIONS:
Documentation
Comment: The vendor was not documented in the reagent logbook for pH buffers. NC WW/GW
LC Quality Assurance Policies for Field Laboratories states: All chemicals, reagents, standards
and consumables used by the laboratory must have the following information documented: Date
Received, Date Opened (in use), Vendor, Lot Number, and Expiration Date. Consumable
materials such as pH buffers and lots of pre -made standards are included in this requirement.

Acceptable corrective action (i.e., the logbook was updated to include the vendor) was performed
by the laboratory and approved by the auditor during the inspection. No further response is
necessary for this Finding.
Comment: The laboratory benchsheet was lacking pertinent data: facility name. The NC
WW/GW LC Approved Procedure for the Analysis of Temperature and NC WW/GW LC
Approved Procedure for the Analysis of pH documents state: The following must be documented
in indelible ink whenever sample analysis is performed: facility name. Acceptable corrective action
(i.e., updated the benchsheet to include facility name) was performed by the laboratory and
approved by the auditor during the inspection. No further response is necessary for this
Finding.
Comment: The pH laboratory benchsheet was lacking pertinent data: instrument identification.
The NC WW/GW LC Approved Procedure for the Analysis of pH document states: The following
must be documented in indelible ink whenever sample analysis is performed: instrument
identification. Acceptable corrective action (i.e., updated the laboratory benchsheet to include
instrument identification) was performed by the laboratory and approved by the auditor during the
inspection. No further response is necessary for this Finding.
Proficiency Testing
Comment: The laboratory was not documenting pH PT sample analyses in the same manner
as environmental samples. PT sample results were documented directly on the vendor report
form and not on the benchsheet. The Proficiency Testing Requirements, February 20, 2012,
Revision 1.2. document states: All PT sample analyses must be recorded in the daily analysis
records as for any environmental sample. This serves as the permanent laboratory record.
Notification of acceptable corrective action (i.e., a statement that beginning with the 2017 PT
study, PT samples will be analyzed and documented like the regular samples on the
benchsheet) was received by email on May 10, 2017. No further response is necessary for
this Finding.
IV. PAPER TRAIL INVESTIGATION:
The paper trail consisted of comparing original records (e.g., laboratory benchsheets, logbooks,
etc.) and contract lab reports to eDMRs submitted to the North Carolina Division of Water
Resources. Data were reviewed for Duke Power Company LLC d/b/a Duke Energy Carolinas —
Dan River (NPDES permit # NC0003468) for November and October 2016 and January 2017.
No transcription errors were detected. The facility appears to be doing a good job of accurately
transcribing data.
V. CONCLUSIONS:
All Findings noted during the inspection were adequately addressed prior to the completion of this
report. The inspector would like to thank the staff for its assistance during the inspection and data
review process. No response is required.
