Subject: April 2020 NPDES Monitoring Report
Galvan Industries, Inc.
Dear Mr. Londhe,
The purpose of this report is to provide the results of qualitative and quantitative stormwater
monitoring conducted on April 20, 2020 at the above -referenced site (Site). The monitoring was
performed in general accordance with NPDES General Permit (GP) # NCG030000 (effective
November 1, 2018 through May 31, 2021).
Qualitative Monitoring
On April 20, 2020, HDR Engineering, Inc. of the Carolinas (HDR) mobilized to the Site to conduct
monthly qualitative monitoring of Outfalls (OF #1, #3 through #5) and Top of Hill (TOH-1) leading
down to the rail right of way (ROW).
OF #1 is located on the northeast corner of the Site and Galvan Way. Flowing water in this outfall
was light tan in color and odorless. There were trace amounts of suspended solids and trace
floating solids. No oil sheen was visible. No evidence of erosion or deposition was present. No foam
was present during the sampling event. A filter sock was present upgrade of OF #1 and care was
taken to ensure that the sample was taken downstream of the filter sock.
OF #3 is located on the southwest corner of the Site. Flowing water in this outfall was light tan and
odorless. There were trace amount of suspended solids. No floating solids or oil sheen were visible.
Slight erosion was present with no evidence of deposition observed. No foam was present during
the sampling event.
OF #4 is located on the northwest comer of the Site. Flowing water in this outfall was clear and
odorless. There were no visible suspended solids or floating solids. No oil sheen was visible at this
outfall. No evidence of erosion or deposition was present. No foam was present during the
sampling event.
OF #5 is located in the middle of the Site. Waterflows from the Blast Building eastward to the
outfall. It should be noted that water also flows into this outfall from the adjacent Highway 49. Water
in the outfall was light tan in color and odorless. Minor suspended solids were observed in the
flowing water at this outfall. It was without noticeable floating solids and foam. No evidence of
erosion or deposition was present. A filter sock was present upgrade of OF #5 and care was taken
to ensure that the sample was taken downstream of the filter sock.

The TOH-1 location is down -gradient of the galvanizing building. The NCDEQ requested that
Galvan collect a sample of surface water runoff from this location to further evaluate the site -
specific contribution to stormwater quality. Originally, TOH-1 was located at the top of the recent
earthwork. It has subsequently been moved west to the rip rap drainage feature and is adjacent to
the former groundwater treatment system. Stormwater runoff was tan to brown in color and
odorless. It was without noticeable suspended solids. Minor floating solids were observed. No
evidence of erosion, deposition, or foam was visible. A filter sock was present upgrade of TOH-1
and care was taken to ensure that the sample was taken downstream of the filter sock.
Quantitative Monitoring
Subsequent to qualitative observations, HDR collected three stormwater samples for quantitative
analysis as follows:
OF #1 was analyzed for:
• Total Suspended Solids (TSS) using SM 2540D
• pH using EPA 9040
• Copper, lead, and zinc using EPA200.7
• Non -polar Oil and Grease/Total Petroleum Hydrocarbons (O&G/TPH) using EPA 1664B
• Total Toxic Organics using EPA608 (pesticides and PCBs), EPA625 (semi -volatile
organics), and EPA 624.1 (volatile organics)
OF #5 and the TOH-1 location were analyzed for:
• TSS using SM 2540D
• Copper, lead, and zinc using EPA200.7
Samples were collected in certified clean sample containers provided by Pace Analytical Services,
LLC (Pace) and transported under chain -of -custody to Pace for analysis. The results of analyses
indicate that benchmark values identified in the GP were exceeded, as follows:
• OF #1
o TSS: 131 mg/L (Benchmark: 100 mg/L)
o Copper: 0.1920 mg/L (Benchmark: 0.007 mg/L)
o Zinc: 6.09 mg/L (Benchmark: 0.067 mg/L)
• OF #5
o Copper: 0.0253 (Benchmark: 0.007 mg/L)
o Zinc: 3.70 mg/L (Benchmark: 0.067 mg/L)
• TOH-1
o TSS: 154 mg/L (Benchmark: 100 mg/L)
o Copper: 0.1370 mg/L (Benchmark: 0.007 mg/L)
o Lead: 0.1110 mg/L (Benchmark: 0.03 mg/L)
o Zinc: 34.5 mg/L (Benchmark: 0.067 mg/L)
It is noted that OF #2, installed by NCDOT, is not currently being sampled. During construction, OF
#2 was not representative of Site conditions due to ongoing earthwork and surface water drainage
re-routing. Subsequent to completion of construction, OF #2 appears stable and may be
reconsidered as a representative outfall for the Galvan site.

In accordance with the GP, Gahran had previously been required to comply with Tier Two
requirements. These include (in addition to those requirements outlined in Tier One) monthly
sampling of permitted outfalls (continued until three consecutive sample results fall below orwithin
the appropriate benchmark or benchmark range), submittal of "no flow" reports if sufficient
discharge does not occur in any given month, and maintenance of a record of all Tier Two reports in
the Stormwater Pollution Prevention Plan (SPPP).
Galvan is currently required to comply with Tier Three requirements. The Tier Three requirements
state that, if, during the duration of the GP, exceedances occur for any specific parameter on four
occasions, Galvan must contact the DWQ Regional Supervisor within 30 days of receipt of the
fourth result. This is the twenty-first sampling event since March of 2015 with a TSS exceedance,
the twenty-second event with a copper exceedance, the twentieth event with a lead exceedance,
and the twenty-second event with a zinc exceedance. As such, Galvan should notify NCDEQ in
accordance with the GP. Note that per NCDEQ requirements, Galvan applied for a NPDES
Stormwater Individual Permit on March 15, 2019. To date, NCDEQ has not responded to that
permit application, thus, Galvan continues to operate under the GP.
Please do not hesitate to contact the undersigned at 704.338.6787 if you have questions or
comments regarding this report. We appreciate the opportunity to continue to assist Galvan on this
project.
Sincerely,
HDR Engineering, Inc. of the Carolinas

All permits require qualitative monitoring to be performed during a "measurable storm event."
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 DEMLR
Regional Office.

QUALIFIERS
Project: GALVAN STORMWATER
Pace Project No.: 92474369
DEFINITIONS
DF - Dilution Factor, if reported, represents the factor applied to the reported data due to dilution of the sample aliquot.
ND - Not Detected at or above adjusted reporting limit.
TNTC - Too Numerous To Count
J - Estimated concentration above the adjusted method detection limit and below the adjusted reporting limit.
MDL -Adjusted Method Detection Limit.
PQL - Practical Quantitation Limit.
RL - Reporting Limit - The lowest concentration value that meets project requirements for quantitative data with known precision and
bias for a specific analyte in a specific matrix.
S - Surrogate
1,2-Diphenylhydrazine decomposes to and cannot be separated from Azobenzene using Method 8270. The result for each analyte is
a combined concentration.
Consistent with EPA guidelines, unrounded data are displayed and have been used to calculate % recovery and RPD values.
LCS(D) - Laboratory Control Sample (Duplicate)
MS(D) - Matrix Spike (Duplicate)
DUP - Sample Duplicate
RPD - Relative Percent Difference
NC - Not Calculable.
SG - Silica Gel - Clean -Up
U - Indicates the compound was analyzed for, but not detected.
Acid preservation may not be appropriate for 2 Chloroethylvinyl ether.
A separate vial preserved to a pH of 4-5 is recommended in SW846 Chapter 4 for the analysis of Acrolein and Acrylonitrile by EPA
Method 8260.
N-Nitrosodiphenylamine decomposes and cannot be separated from Diphenylamine using Method 8270. The result reported for
each analyte is a combined concentration.
Pace Analytical is TNI accredited. Contact your Pace PM for the current list of accredited analytes.
TNI - The NELAC Institute.
ANALYTE QUALIFIERS
H3 Sample was received or analysis requested beyond the recognized method holding time.
L1 Analyte recovery in the laboratory control sample (LCS) was above QC limits. Results for this analyte in associated
samples may be biased high.
M1 Matrix spike recovery exceeded QC limits. Batch accepted based on laboratory control sample (LCS) recovery.
P5 The EPA or method required sample preservation degrades this compound, therefore acceptable recoveries may not be
achieved in sample matrix spikes.
c3 Analysis of 2-chloroethyl vinyl ether was performed from a sample that was field preserved to pH < 2 with HCI. Acid
preservation is not allowed for this parameter by the test method or for NPDES compliance per 40CFR Part 136.
