To Whom IL May Concern:
Hexion Specialty Chemicals, Inc. (Hexion) operates under NPDES Permit No.
NCS000156. As apart of this permit, Hexion is required to submit Discharge Monitoring
Reports (DMRs) for periodic stormwater analytical sampling. Currently, the facility is in
Tier Three status, as outlined in Part II, Section B of the permit, which requires monthly
sampling. In addition, the facility is required to complete Annual Acute Toxicity Testing
at each of the outfalls. Note that there was no measurable discharge for the month of
March.
Please find enclosed the completed DMR Form for the March 2020 sampling event,
which includes analytical sampling results, as well as the annual acute toxicity test.

Regional Environmental Leader, Jeff Hamilton at [phone]

Sincerely,
