SECTION
Hexion Specialty Chemicals, Inc. (Hexion) operates under NPDES Permit No.
NCS000332. As a part of this permit, Hexion is required to submit semiannual
Discharge Monitoring Reports (DMRs). The facility submitted the DMR for ammonia,
Chemical Oxygen Demand (COD) and pH for Period "1 testing (October 2018 to March
2019) on April 30, 2019. As noted in the DMR, the formaldehyde was tested outside of
the EPA specified holding time of 72 hours (method 8315) due to lab logistics, and was
therefore invalid.
The facility retested formaldehyde on May 20, 2019. This DMR serves to report results
for formaldehyde for Period "1 (October 2018 to March 2019). Please find enclosed the
completed DMIZ Form (Attachment]) and the analytical testing report (Attachment 2).
Also included is an additional copy of the form, as required by Permit NCS000332.
If you have any questions or require any additional information, please contact me at
