Inspection Summary:
Facility Description:
Gerdau Ameristeel US Inc. is a steel manufacturer that is located at 6601 Lakeview Road on approximately 106 acres.
Compliance History:
A review of Charlotte -Mecklenburg Storm Water Services (CMSWS) files was conducted. A Notice of Violation was issued
by CMSWS for a diesel spill that occurred on July 30, 2012.
Industrial Operations/City of Charlotte Stormwater Ordinance Review:
Aboveground Storage Tanks (ASTs) —
A double -walled, diesel aboveground storage tank (AST) is located near the scrap yard. Several fuel ASTs and ASTs holding
lubricants were observed near the slag sorting area. No stormwater issues were noted at the time of the inspection.
Outdoor material storage area(s) —
Large scrap metal piles, piles of scaling material and large piles of slag are located outdoors and exposed to stormwater.
Oil/water separator and/or Pretreatment -
The facility has an oil/water separator near the AST in the scrap yard. No stormwater issues were observed.
Additional Observations
Dry weather Flows —
Water is sprinkled over hot slag, and the water is allowed to discharge to the west pond. A review of the permit indicates
DWQ is aware of the slag quench water that is discharged to the west pond. It was noted the water from the west pond can
be pumped to the south pond, and from there it can be pumped to the north pond. The slag quench water is ultimately
discharged from the west and south ponds.
During the inspection a dry weather flow (DWF) was observed in the stormwater ditch near the south pond. A discussion
between the inspector and accompanying facility personnel indicated that stormwater from the capped, inactive hazardous
waste landfill takes several days to drain, and that the landfill cap is checked annually. A second source of the DWF, as
discussed with the accompanying facility personnel, may have been treated leachate water that is pumped from a leachate
tank to the stormwater ditch. It was noted that water discharging to the stormwater ditch was being pH adjusted. The
stormwater ditch is one of the permittee's stormwater outfall sampling locations.
A review of the permittee's most recent application under NCS000304 does not note any discharges from the capped landfill
on site as possible discharges to the stormwater system. DWQ would like more information regarding possible stormwater
and leachate discharges from the landfill (including any treatment) to determine if permit coverage is needed for these
discharges.

Comment: The permittee should update the list of significant spills to include the diesel spill that occurred on
July 30, 2012.
Qualitative Monitoring
Yes No NA NE
Has the facility conducted its Qualitative Monitoring semi-annually? 0 1:11:11:1
Comment:
Analytical Monitoring Yes No NA NE
Has the facility conducted its Analytical monitoring? 0 1:11:11:1
# Has the facility conducted its Analytical monitoring from Vehicle Maintenance areas? ❑ ❑ 0 ❑
Comment: A review of the analytical monitoring data showed the facility is conducting monthly monitoring
due to the permittee's outfalls being in Tier 2 status. The permittee contacted the Mooresville
Regional Office in 2010 and 2011 regarding the benchmark exceedances.

# Is a copy of the Permit and the Certificate of Coverage available at the site?
# Were all outfalls observed during the inspection?
# If the facility has representative outfall status, is it properly documented by the Division?
# Has the facility evaluated all illicit (non stormwater) discharges?
Yes No NA NE
Comment: The stormwater system consists of drop inlets and ditches that drain to three ponds, and a
stormwater ditch located near the south Dond: no deficiencies with the system were observed.
