1 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.
'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,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 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 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.

Shield Project No. 1140109-04
Dear Ms. Carter and Ms. Teofilak:
Shield Engineering, Inc. (Shield) was unable to collect stormwater samples for Stormwater
Discharge Outfall (SDO) #001 and SDO #002 at the Mount Holly facility for the month of
August 2016. According to rainfall data collected for the month, qualifying storm events
occurred on August 5th, August 1561, August 21S1, and August 28th, measuring 0.37 inches, 0.11
inches, 0.29 inches, and 0.36 inches, respectively. An additional 0.45 inches and 0.19 inches of
1 rain were measured on August 7th and August 8th, respectively. Each of these events took place
after normal business hours or within 72 hours of the last qualifying storm event. As the
seasonal type of storm event has now changed to high intensity, short duration events, 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. Shield was able to
collect a sample and perform a visual assessment during the next qualifying storm event on
September 21'. The Qualitative Monitoring Report Form and pH data for that event will be
forthcoming.
Daimler's Mount Holly facility remains in Tier Three of the NPDES General Permit No.
NCG030000. 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,
