The Qualitative Monitoring Report for SDOs #001, #002, and #003 and a partially completed Discharge Monitoring Report form are attached to this cover letter. In addition, the analytical results for the stormwater samples collected during the qualifying storm event on September 2, 2016 are attached to this covet' letter. Results from the September 2" sampling event show an exceedance of the following parameters at or above the corresponding benchmarks: • SDO#001 (09/02/16)—Copper—0.0141 mg/L(Benchmark 0.007 mg/L) • SDO#001 (09/02/16)—pH—9.1 S.U. (Benchmark 6.0-9.0 S.U.) • SDO#003 (09/02/16)—Copper—0.0131 mg/L(Benchmark 0 007 mg/L) Daimler's Gastonia facility remains in Tier Three of the NPDES General Permit No.NCG030000 at SDO #001 for Copper. Shield will continue to perform monthly sampling at SDO #001 per Tier Two requirements until instructed to halt by either Daimler or the State. 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.

Unattendedsitesmay be eligible for a waiver of the rain gauge requirement. 4 See General Permits Table 3 identifying the especially sensitive receiving,water classifications where the more protective benchmark applies. 5 Total Toxic Organics sampling is applicable only for those facilities which perform metal finishing,operations,manufacture semiconductors,manufacture electronic crystals,or manufacture cathode ray tubes. 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 rnanal:ng compliance with the permit monitoring requirement for total toxic organics (TT0),I certify that to the best of my knowledge and belief, no dumping of concentrated toxic organics into the stormwater or areas which are exposed to rainfall 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." <,..)
