Evonik Corporation located at 2401 Doyle Street, Greensboro, Guilford County, North Carolina in accordance with National
Pollution Discharge Elimination System (NPDES) permit number NCS000010 is submitting a copy of our March 2020 Discharge
Monitoring Report (DMR).
This DMR represents a semi-annual monitoring event for the pollutants as required by the storm water permit. The March
analyses indicate that Total Iron was above the benchmark monitoring value (BMV) at the site's storm water discharge outfalls
1, 2 and 4, Total Zinc was above the BMV at outfalls 1 and 4,. and Total Suspended Solids was above at outfall 1. All other analyses
were below the benchmark. Per a letter dated April 7, 2017 from NCDEQ, Evonik has been granted a waiver to tiered response
monitoring for Iron and Zinc, therefore no tiered response is required for these exceedances. This is the first exceedance of Total
Suspended Solids.
Evonik will continue to collect outfall samples, as appropriate, as qualifying rain events allow under semi-annual monitoring. If
you have any questions or concerns, please feel free to contact me at [phone], or our environmental consultant, Tony
Rossano of Antea Group at [phone].
Sincerely,
dva�l

All permits require qualitative monitoring to be performed during a "measurable storm event."
A "measurable storm event" is a storm event that results in an actual discharge from the permitted site
outfall. The previous measurable storm event must have been at least 72 hours prior. The 72-hour storm
interval does not apply if the permittee is able to document that a shorter interval is representative for
local storm events during the sampling period, and the permittee obtains approval from the local DEMLR
Regional Office.
