GENERAL LAB
SOP EXPLANATION
1
Is the SOP reviewed at least every 2 years? What is the most recent review/revision date of the SOP? [Non-field: 15A NCAC 2H .0805 (a) (7)] [Field: 15A NCAC 2H .0805 (g) (4)] Date:

Quality assurance, quality control, and Standard Operating Procedure documentation shall indicate the effective date of the document and be reviewed every two years and updated if changes in procedures are made. Verify proper method reference. During review notate deviations from the approved method and SOP.
2
Are all review/revision dates and procedural edits tracked and documented? [Non-field: 15A NCAC 2H .0805 (a) (7)] [Field: 15A NCAC 2H .0805 (g) (4)]
Each laboratory shall have a formal process to track and document review dates and any revisions made in all quality assurance, quality control and SOP documents.
3
Has the laboratory developed and implemented a documented training program? [Non-field: 15A NCAC 2H .0805 (a) (7) (P)] [Field: 15A NCAC 2H .0805 (g) (5)]

Each laboratory shall develop and implement a documented training program that includes documentation that: (i) [or (A)] that staff have the education, training, experience, or demonstrated skills needed to generate quality control results within method-specified limits and that meet the requirements of these Rules; (ii) [or (B)] that staff have read the laboratory quality assurance manual or applicable Standard Operating Procedures; (iii) [or (C)] that staff have obtained acceptable results on Proficiency Testing samples pursuant to Rule .0803(1) of this Section or other demonstrations of proficiency (e.g., side-by-side comparison with a trained analyst,
acceptable results on a single-blind performance evaluation sample, an initial demonstration of capability study prescribed by the reference method).
4 Is there North Carolina data available for review?
5 Are ALL analytical records, including original observations maintained for 5 years? [Non-field: 15A NCAC 2H .0805 (a) (7) (E)] [Field:15A NCAC 2H .0805 (g) (1)]
6 Are all manual data and log entries written in indelible ink? [Non-field:15A NCAC 2H .0805 (a) (7) (E)] [Field:15A NCAC 2H .0805 (g) (1)]
7 Are error corrections performed properly? [Non-field:15A NCAC 2H .0805 (a) (7) (E)] [Field:15A NCAC 2H .0805 (g) (1)]
All documentation errors shall 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.

Revised: 3/8/2022
Wite-Out®, correction tape, or similar products designed to obliterate documentation shall not
to be used; instead, the correction shall be written adjacent to the error. The correction shall be initialed by the responsible individual and the date of change documented.
8 Are the following items documented with each analysis? [Non-field:15A NCAC 2H .0805 (a) (7) (F)] [Field:15A NCAC 2H .0805 (g) (2)]
The method or SOP reference
Laboratory identification
Instrument identification
Sample collector
Signature or initials of the analyst
Sample identification
Date of sample collection One date and time may be documented for sample collection and analysis if there is documentation showing that the analysis is performed in situ, or immediately on the sample site. When this "one time” option is used, state that the documentation is both collection and analysis time.
Time of sample collection
Date of sample analysis
Time of sample analysis
Proper units of measure
Final value to be reported
Unless greater precision is required by the permit or data receiving agency, it is recommended that all temperature reported for compliance monitoring, be reported in whole numbers as recommended by the DWR “Precision in Discharge Monitoring Reports” document.
Facility name or permit number [NC WW/GW LCB Approved Procedure for the Analysis of Temperature]

PRESERVATION and STORAGE LAB
SOP EXPLANATION
9 Is the sample analyzed within 15 minutes of collection? [40 CFR Part 136.3, Table II and footnote 2]
PROCEDURE – SAMPLE ANALYSIS LAB
SOP EXPLANATION
10 Is the temperature-measuring device immersed in the sample to the proper depth as specified by the manufacturer? [NC WW/GW LCB Approved Procedure for the Analysis of Temperature]
QUALITY ASSURANCE L A B
S O P EXPLANATION
11 Does the compliance temperature-measuring device have a valid (i.e., not expired) NIST certificate? [NC WW/GW LCB Approved Procedure for the Analysis of Temperature]
12
If the compliance temperature-measuring device does not have a valid NIST certificate, is the device checked against a Reference Temperature-Measuring Device initially before use? [NC WW/GW LCB Approved Procedure for the Analysis of Temperature]

This may be performed by a contract laboratory. Maintain comparison data and documentation of NIST traceable temperature-measuring device information listed below.
13
Are all compliance temperature-measuring devices checked against a Reference Temperature-Measuring Device every 12 months after first use or after certificate expiration, whichever comes first? [NC WW/GW LCB Approved Procedure for the Analysis of Temperature]

14
Is the Reference Temperature-Measuring Device, within its expiration date, only used to verify the calibration of other devices and have a stated accuracy of at least ± 0.5 °C? [NC WW/GW LCB Approved Procedure for the Analysis of Temperature]

15
Is the serial number, stated accuracy and expiration date of the Reference Temperature-Measuring Device used in the comparison documented? [NC WW/GW LCB Approved Procedure for the Analysis of Temperature] Reference Temperature-Measuring Device Serial #: __________________________ Stated accuracy: ___________________ Expiration date: ____________________

16
Is the compliance temperature-measuring device checked at two temperatures that bracket the range of compliance samples? [NC WW/GW LCB Approved Procedure for the Analysis of Temperature]

17
Is the date of the verification, the serial number of the compliance temperature measuring device and all four temperatures
documented? [NC WW/GW LCB Approved Procedure for the Analysis of Temperature] Date:___________________ Serial Number:___________ Temperatures: Compliance device Reference device ________ _______ ________ _______

18 Do the readings from both devices agree within 0.5°C? [NC WW/GW LCB Approved Procedure for the Analysis of Temperature]
19
If the compliance temperature-measuring device does not agree within ±0.5°C, is the device taken out of use for compliance temperature monitoring? [NC WW/GW LCB Approved Procedure for the Analysis of Temperature]

If the device reading differs by more than 0.5°C from the Reference Temperature-Measuring Device, it may not be used. No temperature correction factors are allowed for this parameter.
20 Is the verification documentation kept on file for 5 years? [NC WW/GW LCB Approved Procedure for the Analysis of Temperature]
