Carolina Shield Project No. 1140109-08 Dear Mr. Quarry: Shield Engineering, Inc. (Shield) successfully collected monthly stormwater samples for Stormwater Discharge OutfalIs (SDO) 4001 and 4002 at the Mount Holly facility for the month of February 2021. During the February 11 ' sampling event, Shield's field measurements of pl-I were 7.4 for both SDO 8001 and SDO #002. In addition to collection of samples, Shield performed Qualitative Monitoring at SDO #001 and #002. The QMR for SDO #002 shows that during the inspection, a light oil sheen was observed in the stormwater discharge. Shield recommends that the facility inspects the areas that drain into SDO #002 in order to determine the source(s) of oil. A partially completed discharge monitoring report (DMR) is attached, as well as the analytical results and Qualitative Monitoring Report Forms. The person designated to act as the permittee by Daimler Trucks — Mount Holly facility should sign pages 1 and 2 of the DMR_ The signed DMR form should then be mailed to the regulatory agency regional office at Mooresville, NC. Results from the February 111 sampling event show an cxcccdance for Zinc at SDO #001 and #002 and an exceedance for Copper at SDO #002. Daimler remains in Tier 3 at SDO #001 and SDO #002 for Zinc, Copper and TSS. Shicld will continue to perform monthly sampling per Tier 2 requirements until instructed to decrease sampling frequcncy by Daimler.
