Dear Mr. Smith,
S&ME Inc. (S&ME) is submitting the attached Tier Two Stormwater Discharge Outfall
(SDO) Monitoring Report on behalf of TT&E Iron and Metal, Inc. (TT&E). TT&E is
currently permitted to discharge stormwater consistent with General Permit No.
NCG030000 and Certificate of Coverage No. NCG030013. The stormwater discharge
outfall (SDO) monitoring report for the stormwater samples collected at SDO-1 and SDO-2
during the March 24, 2013 rain event is attached.
Results of the March 2013 analyses indicate that the results for total copper and total zinc
exceeded the respective benchmark values for the samples collected from SDO-1 and
SDO-2 during the Tier II sampling event.
For the March 2013 sampling event, TT&E also collected an "Upstream" stormwater
sample from a ditch located on the upgradient side of the TT&E property that flows
through the site and ultimately discharges through stormwater outfall SDO-1. The
concentrations of zinc and copper for the "Upstream" sample were 0.13 and 0.018 mg/L,
respectively. These concentrations for zinc and copper reported in the upstream sample are
above the NPDES established benchmark values for these metals prior to even coming in
contact with on -site materials or stormwater runoff at TT&E.

Tier Two Stormwater Discharge Outfall Monitoring — March 2013 S&ME Project No. 1054-06-493G
TT&E Iron and Metal Inc, Garner, Wake County, NC April 30, 2013
TT&E has also been collecting a stormwater sample from a culvert that runs from the
"Upstream" sample, collects stormwater runoff from catch basins in the southern part of
the facility, and then discharges on the north side of the parking lot. The "parking lot"
sample is collected at a location upgradient of TT&E's internal water system (IWS), which
is upstream of stormwater outfall SDO-1. The concentrations of copper, lead, and zinc
reported for this "parking lot" stormwater sample were 0.15 mg/L, 0.029 mg/L and 0.15
mg/L, respectively. The copper, lead and zinc results for SDO-1, after stormwater flowed
through the IWS system, were 0.033 mg/L, 0.012 mg/L and 0.18 mg/L, respectively. The
0.007 mg/L benchmark value for copper was exceeded, but the concentration of copper was
reduced after IWS treatment. The 0.03 mg/1 benchmark value for lead was met at both the
"Parking lot" and SDO-1 Iocations though the value was reduced after treatment. The
concentrations for zinc at both locations were similar and were above the permit zinc
benchmark value of 0.067 mg/L.
Based on data collected on -site by S&ME, it appears that there may be a correlation
between total suspended solids (TSS) and heavy metals. The AIpha & Omega Group
designed a BMP system that they believe will lower TSS, which may in turn lower the
concentrations of heavy metals in stormwater. The Alpha & Omega Group proposed an
internal water system (IWS) that allows sufficient surface storage to meet detention
requirements while reducing TSS. The IWS is similar in nature to the approved design in
the State DWQ manual. TT&E has installed the IWS on the southern pond and is
monitoring the results prior to implementing the design on the northern pond. The IWS
system has been constructed.
In summary:
o The concentrations of lead continue to be below the benchmark values at both
SDO-1 and SDO-2.
m The concentrations of copper and zinc were above the benchmark values at both
SDO-I and SDO-2.
o The concentration of copper in the Parking Lot sample is approximately one order
of magnitude greater than the Upstream sample.
o For this sampling event, stormwater flowing onto TT&E's from an upstream
location may be contributing to the total concentration of zinc at outfall SDO-1.
In response to these results, TT&E continues to implement the Tier Two response in
accordance with Part II Section B of General Permit No. NCG030000. Besides TT&E
conducting regular inspections of the existing retention basins and sand filters between
storm events, they are also performing regular housekeeping of the site and the retention
basins.
TT&E has also obtaining proposals from specialty contractors for the possible design and
installation of a structural stormwater retention/water reuse system for outfall SDO-2
should another type of system be required.
Results of the March 2013 analyses and the corresponding Tier Two response will be
documented in TT&E's Stormwater Pollution Prevention Plan.

To Whom It May Concern:
S&ME Inc. (S&ME) is submitting the attached Tier Two Stormwater Discharge Outfall
(SDO) Monitoring Report on behalf of TT&E Iron and Metal, Inc. (TT&E). TT&E is
currently permitted to discharge stormwater consistent with General Permit No.
NCG030000 and Certificate of Coverage No. NCG030013. The stormwater discharge

Results of the February 2013 analyses indicate that the results for total copper and total
zinc exceeded the respective benchmark values for the samples collected from SDO-1 and
SDO-2 during the Tier lI sampling event.
In response to these results, S&ME has been working with TT&E to implement the Tier
Two response in accordance with Part II Section B of General Permit No. NCG030000.
Besides TT&E conducting regular inspections of the existing retention basins and sand
filters between storm events, they are also performing regular housekeeping of the site and
the retention basins. In addition, TT&E contracted the services of the Alpha Omega
Group to assist them in the design of a best management practices (BMP) system to assist
in the reduction of the metals in the stormwater at SDO-1.
There are two technical matters at the TT&E site. One is that of water quality in regards to
the heavy metals concentrations in the stormwater runoff. The second is that of stormwater
detention. The challenge at TT&E is to find a solution that addresses the quality issue
while maintaining compliance with the Town of Garner. Due to spatial constraints with
existing site grades, improving Stormwater runoff quality while maintaining the detention
requirements is challenging.
