Dear Mr. Kedenburg:
There were no qualifying rainfall events for the month of March 2022 as defined by General Permit No.
NCG030000. As a result, no monthly 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, four rain events or group events occurred on March 71h, March 16th, March 23 rd,
and March 31", producing 3.50 inches, 0.99 inches, 0.34 inches, and 0.56 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
