Shield Project No. 1140109-06
Dear Mr. Quarry:
Shield Engineering, Inc. (Shield) successfully collected monthly stormwater samples for Stormwater Discharge
Outfalls (SDO) #001 and #002 at the Mount Holly facility for the month of January 2020. During the January
2"d sampling event, Shield's field measurements of pH were 7.01 and 6.90,respectively,at SDO#001 and SDO
#002. In addition to collection of samples, Shield performed Qualitative Monitoring at SDO#001 and #002. A
partially completed discharge monitoring report (DMR) is attached, as well as the analytical results and
Qualitative Monitoring Report forms. The person designated to act as the permittee by Daimler Trucks—Mount
Holly facility should sign all "Red" sections of the DMR. The signed DMR form should then be mailed to the
regulatory agency Central Files. Results from the January 2nd sampling event show no exceedances.
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

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.
'See General Permit, Section B,Table 1 to identify 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 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."

Annual Update Summary—2019
Prepared by Shield Engineering, Inc.
It will be the responsibility of Daimler Trucks North America, LLC to amend the Stormwater
Pollution Prevention Plan (SPPP) whenever there is a change in design, construction, operation,
site drainage, maintenance, or configuration of the physical features which may have a
significant effect on potential for the discharge of pollutants to surface waters. All aspects of
the SPPP shall be reviewed and updated as needed on an annual basis.
The current SPPP was reviewed and referenced in the preparation of this SPPP update. The
following reviews were made to this SPPP for Daimler Trucks North America, LLC—Mt. Holly
Truck Plant:
• The Site Map has been updated to reflect current operations without affecting the
narrative description of the SPPP.
• The NCDEQ Integrated Reports (2018) have been reviewed for changes to
impairment listing for the Catawba River. No new TMDLs have been developed.
• Daimler has updated the list of spills and leaks(for the previous 3 years).
• Shield along with Daimler evaluated the stormwater outfalls and a re-certification
for the presence of non-stormwater discharges is attached.
• The effectiveness of on-site stormwater best management practices was evaluated
during a site visit.
• Employee Training records were reviewed and indicate annual training
requirements were met.
• An updated compliance tracking worksheet has been attached, along with the
Annual Summary Data Monitoring Report Form for 2019.
