Attached is the First Semiannual Stormwater Discharge Monitoring Report for 2020 for Dave Steel
Company, Inc. (DSCO).
Methods
Samples were collected on February 5, 2020, 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 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 1.57 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 least 72
hours prior to the sampling. Samples were collected by 12:00 pm on the sampling day. Precipitation
amounts are based on the National Oceanic Atmosphere Administration records of rainfall at the
Asheville Regional Airport and a nearby rain gauge. Calculations of the maximum total flow through the
outfalls on February 5 2020, are included as Attachment i.

Findings
Analytical Results
The laboratory analytical results are summarized in the Discharge Monitoring Report (Attachment ll)
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, lead, and Non -Polar Oil & Grease/Total
Petroleum Hydrocarbons. However, copper and zinc exceeded their respective benchmark values this
monitoring period. Monitoring relief was granted for zinc in 2014, so a tiered response will not be
required for this exceedance. Copper will be considered to have a Tier I status.
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, pH, copper, lead, zinc, and Non -Polar Oil & Grease/Total Petroleum
Hydrocarbons. Therefore, there were no exceedances at SDO 002 for this monitoring period.
The laboratory analytical report and chain -of -custody form are included as Attachment III to this
document.
Qualitative Results
The SDO Qualitative Monitoring Reports did warrant further investigation regarding SDO 001. No
foam, oil sheen, or erosion/deposition was observed at stormwater outfalls SDO 001 and SDO 002.
The SDO 001 discharge did not have many floating solids, but clarity was low and suspended solids
were high. The SDO 002 discharge had moderate clarity with low and moderate levels of floating and
suspended solids, respectively. 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 see the qualitative reports included as Attachment IV for more
information.
Conclusions
SDO 001 had two exceedances for copper and zinc, however only copper will have a Tier I status.
There were no exceedances of benchmark values or obvious indicators of stormwater pollution at SDO
002 during this monitoring event. DSCO will implement the following Tier I response for SDO 001:
1. Conduct a stormwater management inspection of the facility within two weeks of receiving
sampling results.
2. Identify and evaluate possible causes of the benchmark value exceedance.
3. identify potential, and select the specific feasible: source controls, operational controls, or
physical improvements to reduce concentrations of the parameters of concern, and/or to bring
concentrations within the benchmark range.
4. Implement the selected feasible actions within two months of the inspection.
5. Record each instance of a Tier I response in the Stormwater Pollution Prevention Plan. Include
the date and value of the benchmark exceedance, the inspection date, the personnel
conducting the inspection, the selected actions, and the date the selected actions were
implemented.

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

® Yes ❑ No
Please verify whether Qualitative Monitoring must be performed duriny a "representative storrrr
event" or "measurable storm event" (requirements vary, depending on the perinit)-
Qualitative monitoring requirements vary. Most permits require qualitative monitoring to be
performed during a "representative storm event" or during a "measurable Sturm 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 clays) 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 uutfall. 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.
By this sienature, I certify that this report is accurate and complete to the best of my knowledge:
