To whom it may concern:
Please find the enclosed August Stormwater Discharge Outfall (SDO) #001 and #002 forms for
the Daimler Trucks NA, LLC - Mount Holly Truck Manufacturing Plant JMP). The August
stormwater samples were not collected during this month. According to rainfall data collected
for the month, there was no qualifying rain event (as defined by General Permit No.
NCG030000). Shield was successful in September at collecting an adequate sample.
Daimler remains in Tier 3 at SDO #001 and SDO #002 for Zinc and Copper. Shield will continue
to perform monthly sampling per Tier 2 requirements until instructed to decrease sampling
frequency by Daimler.
Should you have any questions, please contact me at 704-822-7034 or

Dear Mr. Quarry:
There were no qualifying rainfall events for the month of August 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 in August. According to rainfall
data' collected for the month, five rain events or group events occurred on August 3', August b�', August
10', August 25', and August 3111, producing 0.28 inches, 0.04 inches, 2.35 inches, 0.32 inches and 0.60
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 4001 and SDO #002 for Zinc, Copper and TSS. Shield will continue to
perform monthly sampling per Tier 2 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 tccl free to contact either of the undersigned at [phone].
