Dear Mr. Johnson:
The Division is in the process of reviewing the Fayetteville Works Butacite
facility source test report that was received by this Division on July 27, 1999. The test
report was for the Scrubber Performance Test performed on May 3 and 28, 1999.
Please note that the test report infers that there was no major issues with the testing
procedure / methodology. Only on page 33 of the test report is there a brief explanation
that a pre -test matrix spike was not successful and that during a post-test matrix spike
(and only after repeated attempts) was it possible to achieve the desired 90% recovery.
Please note that this issue was discussed with Mr. Tom McKinney of our office
who was present for approximately 12 hours during the testing conducted on May 28,
1999. At that time, several different possibilities were discussed in efforts to explain
the difficulty in achieving the desired recovery during the pre- and post -audit procedure.
Mr. Ken Hausle, with KJH Environmental Services, agreed to Mr. McKinney's request
that the test report would address, in detail, the possible explanations for the
auditing problem, identify the most likely explanation for the problem, and justify
the use of the test data obtained on May 28, 1999 to establish compliance with the
National Emission Standard for the Printing and Publishing Industry (40 CFR
Part 63 Subpart KK). Please provide a written response to address these issues that
we can use as a supplement to the stack test report..
Please provide a written response within 30 days. If you have any questions,
please do not hesitate to contact Mr. Tom McKinney, Environmental Engineer, or me
at [phone].
Sincerely, ,
