Please find the enclosed July Stormwater Discharge Outfall (SDO) #001 and #002 forms for the
Daimler Trucks NA, LLC - Mount Holly Truck Manufacturing Plant (TMP). The June 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
continues to monitor in August for an adequate sample.
Daimler remains in Tier 2 at SDO #001 for C.O.D. Shield will continue to perform monthly
sampling at SDO #001 per Tier 2 requirements, and quarterly sampling at SDO #002 until
instructed to decrease sampling frequency by Daimler.
Should you have any questions, please contact me at 704-822-7034 or

Dear Mr. Kedenburg:
There were no qualifying rainfall events for the month of July 2022 as defined by General Permit No.
NCG030000. As a result, no stormwater samples were collected for Stormwater Discharge Outfall (SDO)
#001 at the Daimler Truck— Mount Holly Facility during this month. According to rainfall data' collected
for the month, three rain events or group events occurred on July V, July 1314, and July 25th, producing
1.13 inches, 1.05 inches, and 3.57 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.
The Daimler Truck — Mount Holly Facility remains in Tier 2 for C.O.D at SDO #001. Shield will continue to
perform monthly sampling at SDO #001 per Tier 2 requirements, and quarterly sampling at SDO #002 until
instructed to decrease sampling frequency by Daimler. Shield greatly appreciates the opportunity to
provide environmental services to Daimler Truck 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
