SUBJECT: 2009 Performance Evaluation (PE) Study Requirements and Timetables
In accordance with the provisions of the North Carolina Administrative Code 15A NCAC 2H .0805 (g)
(7), all field parameter certified laboratories are required to participate in a Performance Evaluation (PE)
study at least annually to maintain certification. Field parameter laboratories must also analyze follow-
up PE samples for any parameters graded unacceptable. Failure to complete the required PE studies
and/or follow-up PE results within the allotted time frames may result in enforcement action in
accordance with 15A NCAC 02H .0805 (g) (8).
The following information is provided to enable your facility to complete the North Carolina
Wastewater/Groundwater Laboratory Certification (NC WW/GW LC) performance evaluation for the
year 2009 in the required timeframe.
PE (also known as Proficiency Testing or PT) Schedule
The 2009 calendar year PE schedule for the NC WW/GW LC program will end on October 31, 2009.
NOTE: We must receive the graded resultsfrom the vendor in this office by the October 31, 2009
deadline. Be cautioned against using the October studies because the results may not be in our
office before the October 31, 2009 deadline. If not performing a quick turnaround type sample,
September studies will likely be the latest monthly study that will meet the deadline.
PE Study Guidance
Attached is a list of parameters with the corresponding method codes and technologies. It is the
facility's responsibility to verify that a PE sample, for all certified parameters where available, is
analyzed during the time frame outlined. There are no PE samples available for dissolved oxygen (DO)
and temperature. Late results cannot be used for certification purposes. A PE sample must be
analyzed by each technology for a particular parameter for which your laboratory holds certification.
Example: total residual chlorine by colorimetric (DPD) has five different method codes included for the
colorimetric technology; only one result is required for colorimetric analysis. Double-check the method
codes listed for each analysis; the entire method reference should be listed to ensure proper credit.
The PE samples that you order must be "blind" or "unknown" values, and the results must be submitted
to an accredited vendor for grading purposes. Graded results must be sent directly to NC WW/GW LC
by the accredited vendor. PE samples received from vendors providing "sealed envelopes" with the
correct results enclosed (often called "Corrective Action", "QA" or "QC" samples) may not to be used for
certification purposes. The NC WW/GW LC program will accept quick turn -around type PE samples.
Accredited vendors can be found at the following website: http://h2o.enr.state.nc.us/lab/cert.htm or you
may `go directly to the A2LA website at http://www.a2la.orq/pt/ProficiencyTestinq.cfm. The list of
accredited vendors may change and should be checked each time performance evaluation samples are
ordered.

2009 PE Study Requirements and Timetables
Any' PE sample results analyzed outside the DMR-QA package must be reported by the accredited
vendor to the NC WW/GW LC Program on or before October 31, 2009. Many vendors run concurrent
DMRQA/WPCHEM studies each year. Follow US EPA and vendor instructions for DMR-QA Study 29
PE sample results deadlines. Failure to report the required PE studies by October 31, 2009 or by
the DMR-QA Study 29 deadline will be considered as a first unacceptable result for certification
purposes.
The NC WW/GW LC address is 1623 Mail Service Center, Raleigh, NC 27699-1623. When completing
the reporting forms, please ensure that the correct address is clearly identified for results to be reported
to this office. The laboratory's EPA Lab Code and the State ID number (this may be the lab certification
number) must also be included to ensure proper credit.
Additional parameter -specific PE requirements:
For colorimetric (DPD) procedures, Total Residual Chlorine (TRC) PE samples must be analyzed on
the same spectrophotometric program (i.e., the same wavelength) using the same procedure that is
used for sample analysis. There are two options for achieving this:
1. If a regular level TRC performance evaluation sample is analyzed, it must be diluted to
the verified range of the low level curve. The reported result must then be calculated
using the dilution factor and the TRC value obtained.
2. Since the dilution factor in option 1 may introduce error, it is recommended that a low
level TRC sample be analyzed. This sample should be within the range of your verified
curve on the low level program.
Some vendors include a low-level TRC PE in a Water Pollution (WP) study that can be used for the
DMR-QA study.
DMR-QA Corrective Actions
US EPA's DMRQA Study 29 for selected NPDES permittees is anticipated to begin May 1, 2009 with
ungraded data packets due in before August 28, 2009. Follow the instructions you received in the US
EPA DMRQA Study 29 instruction package for participating NPDES permit holders. Corrective action
plans for DMR-QA studies are to be submitted to the NC WW/GW LC Program State Coordinator, Mr.
Pat Donnelly, by the date indicated by the US EPA DMR-QA 29 instructions (probably December 4,
2009). Selected DMRQA study 29 NPDES permittees should receive packages from EPA in May.
Follow-up PE samples to unacceptable results
NC WW/GW LC will allow the facilities 60. DAYS from the date the results are issued by the
accredited vendors to complete and have vendors submit to NC WW/GW LC all follow-up PE results
for any unacceptable results.
Unacceptable results are defined by 15A NCAC 2H .0803 (15) as follows:
"Unacceptable results" means those results on performance evaluation samples that exceed the
specified acceptable range as indicated by a US EPA accredited vendor.
We hope that this will answer many questions that you may have regarding North Carolina's program
requirements. If you have additional questions or concerns, we may be reached at [phone] or
you may contact your auditor per the information in the table below. Thank you for your continued
cooperation and participation in the WW/GW Laboratory Certification Program of the State of North
Carolina.
