Daimler Trucks of North America LLC - Mount Holly, North Carolina
Shield Project No. 1140109-06
Dear Mr. Quarry:
According to rainfall data collected for the month of February 2020, there were no qualifying rainfall events (as
defined by General Permit No. NCG030000). As a result, no monthly stormwater samples were collected for
Stormwater Discharge Outfalls 9001 and #002 at the Daimler Trucks Mount Holly facility for the month of
February. Shield Engineering, Inc. (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 remains in Tier 3 at SDO #001 and SDO #002 for Zinc and Copper. Shield will continue to perform
monthly sampling per Tier 2 requirements until instructed to decrease sampling frequency by Daimler. Shield
greatly appreciates the opportunity to provide environmental services to Daimler Trucks, 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,

' Monthly sampling (instead of semi-annual) must begin with the second consecutive benchmark exceedance for the same parameter at the same outfali.
2 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.
4 See General Permit, Section B, Table 1 to identify 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).

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 Tf0 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
MO), 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."
