Dear Mr. Quart':
There were no qualifying rainfall events for the month of December 2021 as defined by General Permit No.
NCG030000. As a result, no monthly stormwater samples were collected for Stormwater Discharge Outfalls
(SDO) #00I and SDO 4002 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 December 8', December
I V and December 20, producing 0.81 inches, 0.52 inches, and 0.19 inches of rain, respectively. Ilowever,
each of these events took place after rermal business hours, within 72 hours of the rain event, or did not
produce enough rainfall to collect a sample. According to www.drou<,ht.go, Gaston County is in D2 —
Severe Drought category. The U.S. Drought Monitor (USDM) shows the location and intensity of drought
across the country using a five -category system, from Abnormally Dry (DO) to Exceptional Drought (D4).
The USDM is a joint effort of the National Drought Mitigation Center, USDA, and NOAA. Shield will
continue to monitor daily weather conditions and attempt coordination of appropriate stafl'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 4002 for zinc and at SDO # 002 for Copper. The Facility
remains in Tier 2 for C.O.D. Shield will continue to perform monthly sampling per Tier 3 requirements
