Dear Mr. Frydenlund:
In a February 17, 2010 Letter, DUSA proposed a change to the DUSA QAP. In the proposal,
DUSA requested that: "Table 1 ofthe QAP be amended to require that the analytical procedure
to be used by the Mill's contract analytical laboratory for the analysis of THF method SW8260B
or SW8260C." No other sections of the DUSA QAP were requested to be changed.
On February 22, 2010 DUSA provided (by e-mail) a redline/strikeout of the DUSA QAP showing
the proposed change in Table 1 of the DUSA QAP. DUSA also submitted a clean copy of the
February 22, 2010 DUSA QAP (Rev. 5).
This letter serves as the Executive Secretary approval of the February 22, 2010 DUSA QAP (Rev.
5). Tetrahydrofuran (THF) can now be analyzed by either EPA method SW8260B or SW8260C.
If you have any questions regarding this letter, please contact Phil Goble at [phone].
