NPDES PERMIT #: NC0083089 ADDRESS: P. O. Box 4009 Emerald Isle, NC 28594 CERTIFICATE #: 5635 DATE OF INSPECTION: October 23, 2014 TYPE OF INSPECTION: Field Initial AUDITOR(S): Todd Crawford LOCAL PERSON(S) CONTACTED: Seola Hill, Buck Browder and Shaun Toms I. 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: This was the laboratory’s first inspection. The facility has all the equipment necessary to perform the analyses. The system for traceability of standards and reagents is effective, thorough and easy to follow. Proficiency Testing (PT) samples have been analyzed for all certified parameters for the 2014 proficiency testing calendar year and the graded results were 100% acceptable. Contracted analyses are performed by Environment 1, Inc. (Certification #10). Current quality assurance policies for Field Laboratories and approved procedures for the analysis of the facility’s currently certified parameters were provided at the time of the inspection. III. FINDINGS, REQUIREMENTS, COMMENTS AND RECOMMENDATIONS: Documentation A. Finding: Error corrections are not performed properly. Requirement: 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. Ref: Quality Assurance Policies for Field Laboratories.

Finding: The laboratory benchsheet was lacking pertinent data: Instrument identification. Requirement: The following must be documented in indelible ink whenever sample analysis is performed: Instrument Identification. Ref: NC WW/GW LC Approved Procedure for the Analysis of pH, NC WW/GW LC Approved Procedure for the Analysis of Specific Conductance (Conductivity), NC WW/GW LC Approved Procedure for the Analysis of Temperature, NC WW/GW LC Approved Procedure for the Analysis of Dissolved Oxygen. C. Finding: The analyst is not signing or initialing laboratory benchsheets. Requirement: 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 analytes. Ref: 15A NCAC 2H .0805 (g) (1). pH – Standard Methods, 4500 H+ B-2000 D. Finding: Values were reported that exceed the method specified accuracy of 0.1 units. Requirement: 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. Ref: Standard Methods, 4500 H+ B-2000, (6). Dissolved Oxygen – HACH 10360-2011 Rev. 1.2 (LDO) E. Finding: The laboratory benchsheet was lacking pertinent data: Calibration and calibration time. Requirement: The following must be documented in indelible ink whenever sample analysis is performed: Meter calibration and meter calibration time(s). Ref: NC WW/GW LC Approved Procedure for the Analysis of Dissolved Oxygen. Comment: Proper verification of the Luminescence Dissolved Oxygen (LDO) probe was being performed but was not being documented. The meter reading and time of reading, while in saturated air, must be documented and compared to the Dissolved Oxygen Meter Calibration Verification table and found to be within ± 0.5 mg/L to be considered acceptable. Conductivity – Standard Methods, 2510 B-1997 F. Finding: The laboratory benchsheet was lacking pertinent data: True value of calibration standards. Requirement: The following must be documented in indelible ink whenever sample analysis is performed: True value of the standard used for calibration. Ref: NC WW/GW LC Approved Procedure for the Analysis of Specific Conductance (Conductivity). Page 3 #5635 Bogue Banks Water Corp. G. Finding: The laboratory benchsheet was lacking pertinent data: True value of the calibration verification check standard. Requirement: The following must be documented in indelible ink whenever sample analysis is performed: True value of the calibration verification check standard. Ref: NC WW/GW LC Approved Procedure for the Analysis of Specific Conductance (Conductivity). H. Finding: The Automatic Temperature Compensator (ATC) has not been verified within the last 12 months. Requirement: The ATC must be verified annually (i.e., every twelve months) and the process documented. The ATC must be verified by analyzing a standard at 25 °C (the temperature that conductivity values are compensated to) and a temperature(s) that brackets the temperature ranges of the samples to be analyzed. This may require the analysis of a third temperature reading that is > 25 °C. Ref: North Carolina Wastewater/Groundwater Laboratory Certification Approved Procedure for the Analysis of Specific Conductance (Conductivity). Comment: The last ATC check was performed on 01/29/2013. IV. PAPER TRAIL INVESTIGATION: The paper trail consisted of comparing field testing records and contract lab reports to Discharge Monitoring Reports (DMRs) submitted to the North Carolina Division of Water Resources. Data were reviewed for July, August and September, 2014. 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 lab 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.
