Shield Project No. 1140099-07
Dear Mr. Pennington:
Shield Engineering, Inc. (Shield) was unable to collect monthly stormwater samples for Stormwater Discharge
Outfall 4001 at the Daimler Trucks Gastonia facility for the month of May 2019. According to rainfall data
collected for the month, the only rain event (as defined by General Permit No. NCG030000) of the month began
on May 4 h and extended through May 1 16. This event began on the weekend producing a total of 2.48 inches
of rain over 6 days during that period. As the seasonal type of storm event is moving towards a high intensity,
short duration event, 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. 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's Gastonia facility remains in Tier Three of the NPDES General Permit No. NCG030000 at SDO 9001
for Copper and pH. Shield will continue to perform monthly sampling at SDO 4001 per Tier Two 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 [phone].
Respectfully,
SHIELD ENGINEERING, INC.

rvioiuniy sampling Imsieaci or semi-annuap must begin with the second consecutive benchmark exceedance for the same parameter at the same outfall.
'For sampling periods with no discharge at any single outfall, you must still submit this discharge monitoring report with a checkmark here.
'The 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.
s 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).
Permit Date: 11/1/2012-10/31/2017 SWU-245, last revised 10/25/2012

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 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."

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 me/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.
