Dear Mr. Quarry:
There were no qualifying rainfall events for the month of October 2021 as defined by General Permit No.
NCG030000. As a result, no monthly stormwater samples were collected for Stormwater Discharge Outfalls
(SDO) #001 and SDO #002 at the Daimler Trucks — Mount Holly Facility during this month. According to
rainfall data' collected for the month, three rain events or group events occurred on October 41, October
251 and October 281, producing 0.33 inches, 0.01 inches, and 0.80 inches of rain, respectively. However,
each of these events took place after normal business hours, within 72 hours of the rain event, or did not
produce enough rainfall to collect a sample. Shield will continue to monitor daily weather conditions and
attempt coordination of appropriate staff and resources to facilitate adequate sample collection. A partially
completed Discharge Monitoring Report form is attached to this cover letter for signature of the appropriate
authorized permittee and submittal to the State.
Daimler remains in Tier 3 at SDO #001 and SDO #002 for Zinc and at SDO # 002 for Copper. The Facility
remains in Tier 1 for C.O.D. Shield will continue to perform monthly sampling per Tier 3 requirements
until instructed to decrease sampling frequency by Daimler. Shield greatly appreciates the opportunity to
provide environmental services to Daimler Trucks, North America. If you have any questions in reference
to this document or require further information, please feel free to contact either of the undersigned at (704)
