Dear Sir or Madam:
Attached is the Second Semi -Annual Stormwater Discharge Monitoring Report for 2019 for Dave Steel
Company, Inc. (DSCO).
Methods
Samples were collected on November 23, 2019, during a `measurable 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 preserved when appropriate - 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 pl-I range. The pl-I 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 stormwatcr analytical sampling event. This
monitoring report is attached for reference.
The total precipitation was 0.26 inches for the storm event that resulted in an actual discharge from the
permitted site outfalls. The previous measurable storm event with actual discharge was at ]cast 72 hours
prior to the sampling. Samples were collected by 10:50 am on sampling day. Precipitation amounts are

Analytical Results
� The laboratory analytical results are summarized in the Discharge Monitoring Report (attached) and
discussed below.
SDO 001
The results for SDO 001 indicate that the samples contained concentrations less than or within the range
of the specified benchmark value concentrations for the following parameters measured on -site or at the
laboratory: Total Suspended Solids (TSS), pH, copper, lead, zinc, and Non -Polar Oil & Grease/Total
Petroleum Hydrocarbons. Therefore; there were no exceedances at SDO 001 for this monitoring period.
SDO 002
The results for SDO 002 indicate that the samples contained concentrations less than or within the range
of the specified benchmark value concentrations for all of the parameters measured on -site or at the
laboratory: TSS, pl-I, copper, lead, zinc, and Non -Polar Oil & Grease/Total Petroleum Hydrocarbons.
Therefore, there were no cxceedances at SDO 002 for this monitoring period.
The laboratory analytical report and chain -of -custody form are attached to this document.
Qualitative 12esults
The SDO Qualitative Monitoring Reports did not warrant further investigation. No foam, oil sheen, or
erosion/deposition was observed at stonnwater outfalls SDO 001 and SDO 002, and the discharges had
moderate to good clarity with low to moderate levels of floating and suspended solids. No other
deficiencies were observed at SDO 001 and SDO 002 during the Qualitative Monitoring event, and no
other potential indicators of stormwater pollution were observed. The system was operating as designed
and was in good order with no obvious evidence of pollutant discharges. Please sec the attached
qualitative reports for more information.

Conclusions
"there were no exceedances of benchmark values or obvious indicators of stormwater pollution at either
SDO 001 or SDO 002 during this monitoring event. DSCO will conduct their next semi-annual
monitoring event sometime between January I and June 30, 2020.
Please contact me with operational or compliance issues.

Monthly sampling (instead of semi-annual) must begin with the second consecutive benchmark exceedance for the same parameter at the same outran.
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 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."

Was this a "Representative Storm Event' or "Measureable Storm Event" as defined by the permit?
(See information below.)
® Yes ❑ No
Please verify whether Qualitative Monitoring must he performed during a "representative storm
event" or "measureahle storm event" (requirements vary, depending on the permit).
Qualitative monitoring requirements vary. Most permits require qualitative monitoring to be
performed during a "representative storm event' or during a "measureable storm event." However,
some permits do not have this requirement. Please refer to these definitions, if applicable.
A "representative storm event" is a storm event that measures greater than 0.1 inches of rainfall
and that is preceded by at least 72 hours (3 days) in which no storm event measuring greater than
0.1 inches has occurred. A single storm event may contain up to 10 consecutive hours of no
precipitation.
A "measurable storm event' is a storm event that results in an actual discharge from the
permitted site outfall. The previous measurable storm event must have been at least 72 hours
prior. The 72-hour storm interval does not apply if the permittee is able to document that a shorter
interval is representative for local storm events during the sampling period, and the permittee
obtains approval from the local DWQ Regional Office.
