LABORATORY NAME: Smithfield -Clinton Plant WWTP Laboratory
NC GENERAL PERMIT#: NCG060000
ADDRESS: 424 East Railroad Street
Clinton, NC 28328
CERTIFICATE #: 5655
DATE OF INSPECTION: May 31, 2017
TYPE OF INSPECTION: Field Industrial Maintenance
AUDITOR(S): Tonja Springer
LOCAL PERSON(S) CONTACTED: George Yankay and Rick Bowen
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.
II. 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 the
Findings and Recommendations made 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 Environmental Chemists, Inc. (Envirochem) (Certification
#94).
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
A. Finding: The laboratory needs to increase the traceability documentation of pH buffers.
Requirement: All consumables used by the laboratory must have the following
information documented: Date Received, Date Opened (in use), Vendor, Lot Number,
and Expiration Date. 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. Ref: Quality Assurance Policies for Field Laboratories.
Requirement: Data pertinent to each analysis must be maintained for five years. Ref:
15A NCAC 2H .0805 (g) (1).
Comment: Date received and opened were written on the pH buffer bottles. While this
can provide a traceability link to analyses by looking at the dates that the chemicals were
in use, that link is lost once the bottles are discarded.
Proficiency Testing
B. Finding: The laboratory is not documenting pH PT sample analyses in the same
manner as environmental samples.
Requirement: All PT sample analyses must be recorded in the daily analysis records
as for any environmental sample. This serves as the permanent laboratory record. Ref:
The Proficiency Testing Requirements, February 20, 2012, Revision 1.2.
Comment: The analysis of PT samples is designed to evaluate the entire process used
to routinely report environmental analytical results; therefore, PT samples must be
analyzed and the process documented in the same manner as environmental samples.
Comment: The laboratory is documenting PT sample results directly on the vendor
report form and not on the benchsheet.
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 Town of
Clinton. Data were reviewed for Smithfield — Clinton Plant WWTP Laboratory (NC General
Permit # NCG060000) for April and May 2017. No transcription errors were detected. The
facility appears to be doing a good job of accurately transcribing data.
V. CONCLUSIONS:
Correcting the above cited Findings will help this laboratory to produce quality data and meet
Certification requirements. The inspector would like to thank the staff for its assistance during the
inspection and data review process. Please respond to all Findings and include supporting
documentation and implementation dates for each corrective action.
