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 October 2019 Discharge
Monitoring Report (DMR).
This DMR represents a semi-annual monitoring event for the pollutants as required by the storm water permit. The October
analyses indicate that Total Iron was above the benchmark monitoring value (BMV) at the site's storm water discharge outfalls 2
and 4, and Total Zinc was above the BMV at outfalls 3 and 4. 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.
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,
Ken Meyer

A `Representative Storm Event" is a storm event that measures greater than 0.1 inches of rainfall and that
is preceded by at least 72 hours (3 days) in which no storm event measuring greater than 0.1 inches has
occurred. A single storm event may contain up to 10 consecutives hours of no precipitation.
