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.
II. GENERAL COMMENTS:
Mr. Stogner's records were filed in an orderly manner and easy to retrieve. He was very
forthcoming and very receptive to all necessary changes in response to the small number of items
discovered at the inspection.
All required Proficiency Testing (PT) samples have been analyzed for the 2016 PT calendar year
and the graded results were 100% acceptable.
Contracted analyses are performed by K & W Laboratories (Certification # 559).
Current Quality Assurance Policies for Field Laboratories and Approved Procedure documents
for the analysis of the facility's currently certified methods were provided at the time of the
inspection.
III. FINDINGS REQUIREMENTS COMMENTS AND RECOMMENDATIONS:
Documentation
Comment: Not all traceability information was being retained. The pH buffers are aliquots of a
larger bottle given to the facility by their contract lab. The bottles contain the vendor name, buffer
concentration, lot number and expiration date. The lot number and expiration date of the pH
buffers were documented on the calibration benchsheet. However, the date the aliquot was
received and put into use was not recorded, and the vendor information was lost upon discarding
the bottle. The Quality Assurance Policies for Field Laboratories document 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.

Page 2
#5295 Leonard E. Stogner
This information as well as the vendor and/or manufacturer, lot number, and expiration date must
be retained for chemicals, reagents, standards and consumables used for a period of five years.
Consumable materials such as pH buffers and lots of pre -made standards are included in this
requirement. Notification of acceptable corrective action (i.e., the certificates of analysis for the
current buffers and a statement that all certificates from this point forward will be obtained and
labeled with the date the aliquot was received) was received by email on 6/14/2016. No further
response is necessary for this Finding.
Comment: Error corrections were not properly performed. The Quality Assurance Policies for
Field Laboratories document states: All documentation errors must be corrected by drawing a
single line through the error so that the original entry remains legible. Entries shall not be
obliterated by erasures or markings. Wite-Out®, correction tape or similar products designed to
obliterate documentation are not to be used. Write the correction adjacent to the error. The
correction must be initialed by the responsible individual and the date of change documented.
Notification of acceptable corrective action (i.e., a statement that the practice of error correction
with a single line, date and initials would be implemented on 6/15/2016) was received by email on
6/17/2016. No further response is necessary for this Finding.
Comment: The laboratory is not documenting Proficiency Testing (PT) sample analyses in the
same manner as environmental samples. The Proficiency Testing Requirements 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 the pH PT sample will be documented on the pH
calibration log in the same space as for effluent samples, but with a designation of the PT study
number to distinguish it from the effluent, with implementation beginning with the 2017 PT
sample) was received by email on 6/14/2016. No further response is necessary for this
Finding.
pH — Standard Methods, 4500 H+ B-2000 (Aqueous)
Dissolved Oxygen — Standard Methods, 4500 O G-2001 (Aqueous)
Temperature — Standard Methods, 2550 B-2000 (Aqueous)
Comment: The laboratory benchsheets were lacking pertinent data: Instrument identification.
The NC WW/GW LC Approved Procedure for the Analysis of Dissolved Oxygen, NC WW/GW
LC Approved Procedure for the Analysis of pH and NC WW/GW LC Approved Procedure for
the Analysis of Temperature documents state: The following must be documented in indelible
ink whenever sample analysis is performed: Instrument Identification. Notification of acceptable
corrective action (i.e., updated benchsheets including instrument identification with an
implementation date of 6/14/2016) was received by email on 6/14/2016. No further response is
necessary for this Finding.
Dissolved Oxygen — Standard Methods, 4500 O G-2001 (Aqueous)
Temperature — Standard Methods, 2550 B-2000 (Aqueous)
Comment: Sample analysis time was not clearly documented. There was only one time
documented on the benchsheet, with no statement that the sample was analyzed in situ or on site.
The NC WW/GW LC Approved Procedure for the Analysis of Temperature document states:
The following must be documented in indelible ink whenever sample analysis is performed:
Date and time of sample collection; Date and time of sample analysis - Alternatively, since EPA
requires samples to be analyzed immediately, one time may be documented for collection and
analysis with the notation that samples are measured in situ or immediately at the sampling site
(i.e., immediately following collection at a location as near to the collection point as possible).
When this `one time' option is used, state that the documented time is both collection and

Page 3

analysis time. The NC WW/GW LC Approved Procedure for the Analysis of Dissolved Oxygen
document states: The following must be documented in indelible ink whenever sample analysis
is performed: Date and time of sample collection; Date and time of sample analysis to verify the
15 minute holding time is met. Alternatively, one time may be documented for collection and
analysis with the notation that samples are measured in situ or immediately at the sample site.
Notification of acceptable corrective action (i.e., updated benchsheets including a statement
that "all samples are in stream and instantaneous" with an implementation date of 6/14/2016)
was received by email on 6/14/2016. No further response is necessary for this Finding.
pH — Standard Methods, 4500 H+ B-2000 (Aqueous)
Comment: Values were reported that exceed the method specified accuracy of 0.1 units.
Standard Methods, 4500 H+ B-2000. (6) states: By careful use of a laboratory pH meter with
good electrodes, a precision of ±0.02 unit and an accuracy of ±0.05 unit can be achieved.
However, ± 0.1 pH unit represents the limit of accuracy under normal conditions, especially for
measurement of water and poorly buffered solutions. For this reason, report pH values to the
nearest 0.1 pH unit. Notification of acceptable corrective action (i.e., a statement that rounding
the pH result and reporting it to the nearest 0.1 units will be implemented on the June 2016 DMR,
or the month including the next flow) was received by email on 6/14/2016. No further response
is necessary for this Finding.
Temperature — Standard Methods, 2550 B-2000 (Aqueous)
Comment: Documentation was not available to verify that the NIST thermometer used for
Temperature sensor verification is accurate within ± 0.5 °C. The facility has the temperature
measuring devices verified annually by their contract lab. The verification process documents the
NIST thermometer's serial number, but does not include documentation of the accuracy of that
thermometer. The NC WW/GW LC Approved Procedure for the Analysis of Temperature
document states: NIST traceable temperature measuring devices used for this verification must
have a stated accuracy of at least± 0.5 °C. Document the verification data and keep on file.
Notification of acceptable corrective action (i.e., submitted documentation showing the NIST
thermometer used for verification in 2016 has accuracy within ± 0.5 °C in the range of sample
temperatures and a statement this documentation will be obtained for all future annual
verifications) was received by email on 6/14/2016. No further response is necessary for this
Finding.
Comment: As the auditor stated on the day of the inspection, due to the new Approved
Procedure for the Analysis of Temperature, corrections are no longer applied to Temperature data
used for compliance reporting.
IV. PAPER TRAIL INVESTIGATION:
The paper trail consisted of comparing original records (e.g., laboratory benchsheets, logbooks,
etc.) and contract lab reports to Discharge Monitoring Reports (DMRs) submitted to the North
Carolina Division of Water Resources. Data were reviewed for Norfolk Southern Railway
Company- Linwood Yard (NPDES permit #NC0029246) for April and August 2015 and February
2016. No transcription errors were detected. The facility appears to be doing a good job of
accurately transcribing data.
