The performance evaluation (PE) results submitted by your laboratory from the NSI Performance Evaluation
Study, WP-104 have been received and evaluated. The attached table represents the status for each of your
certified parameters and methods to date. A blank in the "PE complete" column indicates no PE yet recorded
for this calendar year. A "Pass" entry indicates your lab has satisfied the annual performance evaluation
requirement. Other information in this column indicates vendor -and Study identification. A "Fail" entry requires a
follow up sample to be analyzed and reported to this office within 60 days. An N/A entry'represents parameter
exemption from the performance evaluation requirement. A date entered beside the "Fail" entry represents the
completion deadline for this PE follow up.
To date the PE requirement has not been satisfied for all of your certified parameters and methods. You
are reminded that an acceptable performance evaluation (PE) result must be obtained for .all certified parameters
which are available from the accredited vendors. Failure to submit a passing PE result by December 31, 2005. will
be considered a first miss. Failure to analyze and submit an acceptable follow up sample result within 60 days or
producing a second successive unacceptable result will result in decertification for that parameter.
