Bill,

Attached is data concerning NOx emissions from the DuPont Beaumont nitric
acid plant. It is a small, single-pressure plant with NSCR control.

Please note that the CEM NOx data for this plant, and that submitted
yesterday for Pascagoula, contain data associated with periodic CEM QA/QC
activities such as calibrations.

Please let me know if you have any questions or comments.

Regards,
Rick
