(Shield) was unable to collect stormwater samples for Stormwater Discharge Outfall (SDO)#001 at the Gastonia facility for the month of August 2016. According to rainfall data collected for the month, qualifying storm events occurred on August 2nd, August 8th, August 21st, and August 27th, measuring 0.56 inches, 0.21 inches, 0.87 inches, and 0.14 inches, respectively. However, each of these events took place on a weekend day, after normal business hours, or did not occur greater than 72 hours since the last qualifying storm event. As the seasonal type of storm event has now changed to high intensity, short duration events, usually commencing in late afternoon through early evening with little to no notice for preparation, Shield will continue to monitor daily weather conditions and attempt to continue coordination of appropriate staff and resources to facilitate adequate sample collection. Shield was able to collect a substitute sample and perform a visual assessment during the next qualifying storm event which occurred on September 2nd. A partially completed DMR form for the month of August is attached to this cover letter for your signature and submittal to the State. Daimler's Gastonia facility remains in Tier Three of the NPDES General Permit No. NCG030000 at SDO #001. Shield will continue to perform monthly sampling at SDO #001 per Tier 3 requirements until instructed to halt by Daimler. Shield greatly appreciates the opportunity to provide environmental services to Daimler Trucks of 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(704) 394-6913. Respectfully, SHIELD ENGINEERING,INC.

For purposes of this permit the definition of Total Toxic Organics is that definition contained in the EPA Effluent Guidelines for the facility subject to the requirement to sample (for metal finishing use the definition as found in 40 CFR 433.11;for semiconductor manufacture use the definition as found in 40 CFR 469.12;for electronic crystal manufacture use the definition as found in 40 CFR 469.22;and for cathode ray tube manufacture use the definition found in 40 CFR 469.31).

The solvent management plan shall include a list of the total toxic organic compounds used and the other elements listed in the General Permit. For those facilities electing to employ the TTO monitoring waiver,the discharger shall sign the following certification statement: "Based upon my inquiry of the person or persons directly responsible for managing compliance with the permit monitoring requirement for total toxic organics (TM), I certify that to the best of my knowledge and belief,no dumping of concentrated toxic organics into the stormwater or areas which are exposes to rarnfall or stormwater runoff has occurred since filing the last discharge monitoring report. I further certify that this facility is implementing the all the provisions of the solvent management plan included in the Stormwater Pollution Prevention Plan." lArolf Li/MC-5 Name(Print name) VU Titlerant ml e L___,, qi4 /(a (Signature) (Date) Note: Results must be reported in numerical format.
