Dear Mr.Pennington:
Shield Engineering, Inc. (Shield) successfully collected monthly stormwater samples and completed the
qualitative assessment for Stormwater Discharge Outfall (SDO) #001 at the Gastonia facility for the
month of December. The Qualitative Monitonng Report for SDO #001 and a partially completed
Discharge Monitoring Report form are attached to this cover letter. In addition, the analytical results for
the stormwater sample collected during the qualifying storm event on December 6 2016 are attached to
this cover letter. Results from the December 6th sampling event show an exceedance of the following
} parameters at or above the corresponding benchmarks:
SDO#00 (10/07/16)—Copper—0.0121 in
g/I,()3enchmark 0,007 mg/L)
Daimler's Gastonia facility remains in Tier Three of the NPDES General Permit No.NCG030000 at SDO
#001 for Copper and Tier 2 for pH at SDO #001. 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.
Respectfully,

' Monthly sampling(instead of semi-annual) must begin with the second consecutive benchmark exceedance for the same parameter at the same outfall.
2 For sampling periods with no discharge at any single outfall,you must still submit this discharge monitoring report with a checkmark here.
3The total precipitation must be recorded using data from an on-site rain gauge. Unattended sites may be eligible for a waiver of the rain gauge requirement.
`See General Permit,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).

Facilities that incorporate a solvent management plan into the Stormwater Pollution Prevention Plan may so certify,and the requirement for TTO monitoring
may be waived. 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
(TTO), I certify that to the best of my knowledge and belief,no dumping of concentrated toxic organics into the storrnwater 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."

Note: Results must be reported in numerical format. Do not report Below Detection Limit, BDL,<PQL, Non-detect, ND,or other similar non-numerical
format. When results are below the applicable limits,they must be reported in the format, "<XX mg/L",where XX is the numerical value of the detection
limit, reporting limit, etc. in mg/L.
Note: If you report a sample value in excess of the benchmark,you must implement Tier 1, Tier 2,or Tier 3 responses. See General Permit text.
