Maintenance Inspection
Dear Mr. Rich:
Enclosed is a report for the inspection performed on June 21, 2012 by Chet Whiting. Since the
finding(s) cited during the inspection were all corrected prior to the completion of the enclosed
report, a response is not required. The staff is commended for taking the initiative in correcting
the findings in such a timely manner. For certification maintenance, your laboratory must
continue to carry out the requirements set forth in 15A NCAC 2H .0800.
Copies of the checklists completed during the inspection may be requested from this office.
Thank you for your cooperation during the inspection. If you wish to obtain an electronic copy of
this report by electronic mail, or if you have questions or need additional information please
contact me at 828-296-4677.
Sincerely,
Gary Francies

This laboratory was inspected to verify its compliance with the requirements of 15A NCAC 2H .0800 for
the analysis of environmental samples.
II. GENERAL COMMENTS:
The laboratory is neat and well organized and has all the equipment necessary to perform the analyses.
The laboratory had implemented traceability documentation prior to the inspection.
The sample collection and analysis times were documented but it was recommended that the laboratory
clearly identify on the benchsheet which samples are measured insitu and which samples are returned to
the laboratory for analysis. This was done and submitted to this office by fax on July 6, 2012
All of the findings referenced in the comments below were new policies implemented since the last
inspection with the exception of documenting units.
III. FINDINGS, REQUIREMENTS, COMMENTS AND RECOMMENDATIONS:
Documentation
Comment: No instances were observed, however the laboratory was not aware that any data that
does not meet all quality control requirements is required to be qualified on the Discharge Monitoring
Report, including contract laboratory data. The Quality Assurance Policies for Field Laboratories
document states: When quality control (QC) failures occur, the laboratory must attempt to determine
the source of the problem and must apply corrective action. Part of the corrective action is notification
to the end user. If data qualifiers are used to qualify samples not meeting QC requirements, the data
may not be useable for the intended purposes. It is the responsibility of the laboratory to provide the
client or end -user of the data with sufficient information to determine the usability of the qualified data.
Where applicable, a notation must be made on the Discharge Monitoring Report (DMR) form, in the
comment section or on a separate sheet attached to the DMR form, when any required sample quality
control does not meet specified criteria and another sample cannot be obtained.

Comment: Error corrections were not made properly. 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. All data and log entries must be written in
indelible ink. Pencil entries are not acceptable. Notification of acceptable corrective action (i.e., a
statement that the Quality Assurance Policies for Field Laboratories had been reviewed and that error
correction would be performed as required) was received by e-mail on July 6, 2012. No further
response is necessary for this finding.
Comment: The laboratory was not documenting Proficiency Testing (PT) sample analyses in the same
manner as environmental samples (i.e., on a 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 PT sample analyses will be
documented in the same manner as environmental samples) was received by email on July 6, 2012.
No further response is necessary for this finding.
Comment: The laboratory was not documenting the preparation of PT samples. The Proficiency Testing
Requirements, February 20, 2012, Revision 1.2 document states: PT samples received as ampules
must be diluted according to the PT provider's instructions. The preparation of PT samples must be
documented in a traceable log or other traceable format. The diluted PT sample becomes a routine
environmental sample and is added to a routine sample batch for analysis. Notification of acceptable
corrective action (i.e., PT sample preparation will be documented) was received by email on July 6,
2012. No further response is necessary for this finding.
pH — Standard Methods, 18'h Edition, 4500 H+ B
Temperature — Standard Methods, 18t" Edition, 2550 B
Comment: The laboratory was not documenting units for pH and Temperature. The North Carolina
Administrative Code, 15A NCAC 2H .0805 (g) (1) states: Data pertinent to each analysis must be
maintained for five years. Certified Data must consist of date collected, time collected, sample site,
sample collector, and sample analysis time. The field benchsheets must provide a space for the
signature or initials of the analyst, and proper units of measure for all analyses. Notification of
acceptable corrective action (i.e., an updated benchsheet with proper units of measure) was received
by fax on July 6, 2012. No further response is necessary for this finding.
Total Residual Chlorine — Standard Methods, 18th Edition, 4500 CI G
Comment: The 150 pg/L standard for the curve verification fell outside the ± 10% acceptance criterion.
The Technical Assistance for Field Analysis of Total Residual Chlorine (Option 1) states in part: The
curve verification must check 5 concentrations (not counting the blank) that bracket the range of the
samples to be analyzed. This type of curve verification must be performed at least every 12 months. The
values obtained must not vary by more than 10% of the known value for standard concentrations greater
than or equal to 50 uq/L and must not vary by more than 25% of the known value for standard
concentrations less than 50 µg/L. The overall correlation coefficient of the curve must be >_0.995.
Notification of acceptable corrective action (i.e., a new acceptable curve verification) was received by
email on July 2, 2012. No further response is necessary for this finding.
Comment: The acceptable range for a 150 µg/L standard is 135 — 165 µg/L. The previous verified
standard value was 130 µg/L.

Dissolved Oxygen — Standard Methods, 18t" Edition, 4500 O G
Comment: The time the meter was turned on was documented; the calibration time was not
documented. The Technical 'Assistance for Field Analysis of Dissolved Oxygen states in part: The
following criteria must be documented whenever sample analysis is performed. 5. Meter calibration and
time(s) of calibration. Notification of acceptable corrective action (i.e., a statement that the calibration
time is now documented on the benchsheet) was received by email on July 6, 2012. No further
response is necessary for this finding.
IV. PAPER TRAIL INVESTIGATION:
The paper trail consisted of comparing field testing records to the Self Report Form. Data were reviewed
(NPDES Permit # NCO049867 for March, April and May 2012. 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.
