Dear Sir or Madam:
Attached is the Second Semi-Annual Stormwater Discharge Monitoring Report for 2016 for Dave Steel
Company, Inc. (DSCO).
Methods
Samples were collected on November 29, 2016, during a"measureable storm event" from the facility
stormwater outfalls labeled SDO 001 and SDO 002 (see Figure 1). SDO 001 and SDO 002 are the
locations where previous samples have been collected. Samples were collected from the approximate
center of the discharge streams and transferred to laboratory-supplied containers. Samples were
collected using good sampling practices in pre-cleaned- and in some cases preserved- containers
supplied by Pace Analytical Laboratories (Pace). The containers were placed in a cooler on ice and
delivered to Pace in Asheville,North Carolina, for laboratory analyses. pH was measured in the field by
placing a probe within the flow of the respective outfall, and the pH was recorded following
stabilization. The pH meter was calibrated before testing with two buffer solutions that bracketed the
expected pH range. The pH measurement was taken within 15 minutes of collection as required by the
North Carolina Department of Environmental Quality (NCDEQ).
A Dave Steel staff representative also conducted a Stormwater Discharge Outfall (SDO) Qualitative
Monitoring event for SDO 001 and SDO 002 during the stormwater analytical sampling event. This
monitoring report is attached for reference. ,
The total precipitation was 1 inch for the 24-hour period. Samples were collected by 7:55am on
sampling day. Precipitation amounts are based on an on-site rain gauge and the National Oceanic
Atmosphere Administration records of rainfall at the Asheville Regional Airport. There was no
measureable storm event for at least the preceding 72 hours before the sampled storm event.
Calculations of the maximum total flow through the outfall on November 29, 2016, are attached.

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.
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
'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"
