Subject. April 2015 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 March 5. 2014 at the above -referenced site (Site). The monitoring was
performed in general accordance with NPDES General Permit (GP) # NCG030000 (effective
November 1, 2012 through October 31, 2017). A summary of field observations and laboratory
results are presented below. Copies of Stormwater Discharge Qualitative Monitoring Reports
(QMRs) completed during the March 5, 2015 qualitative monitoring event and a copy of the
Stormwater Discharge Monitoring Report (DMR) completed following quantitative analysis of a
sample collected from representative Outfall # 2 are attached for your use.
On March 5"', 2015, HDR Engineering, Inc. of the Carolinas (HDR) mobilized to the Site to conduct
monthly monitoring of Outfalls # 1 through 4.
Outfall # 1 is located on the northeast corner of the Site and Millbrook Road. Flowing water in this
outfall was clear and odorless. It was without noticeable floating or suspended solids, foam, or oil
sheen. No evidence of erosion or deposition was present.
Outfall # 2 is located on the south side of the Site adjacent to the rail line. Flowing water in this
outfall was clear and odorless. Water in the outfall was without noticeable floating or suspended
solids, foam, or oil sheen. Ponded water below the outfall contained suspended solids showing
evidence of erosion in or preceding the outfall.
Outfall # 3 is located on the southwest corner of the Site. At the time of sampling, this outfall was
not flowing.
Outfall # 4 is located on the northwest corner of the Site. Flowing water in this outfall was brown
and odorless. Water in the outfall was without noticeable floating solids, foam, or oil sheen The
water below the outfail contained suspended solids showing evidence of past erosion in or
preceding the outfall-
Subsequent to qualitative observations, HDR collected one stormwater sample from representative
Outfall # 2 for quantitative laboratory analyses consisting of the following tests:
• Total suspended solids (TSS) using SM 2540D
• pH using EPA 9040

• Copper, lead, and zinc using EPA 200.7
• Non -polar oil and grease/total petroleum hydrocarbons (O&G/TPH) using EPA 16646
• Total Toxic Organics using EPA 3510, EPA 625, and EPA 624
Samples were collected in certified clean sample containers provided by Pace Analytical Services,
Inc. (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:
• TSS: 261 mg1L (Benchmark: 100 mg/L)
• Copper: 0.0839 mg/L (Benchmark: 0.007 mg1L)
• Lead: 0.0376 mg/L (Benchmark: 0.03 mg/L)
• Zinc: 50.6 mg/L (Benchmark: 0.067 mg/L)
It is noted that Outfail # 2, recently installed by CSX Transportation, has replaced a previously
decommissioned Outfall # 2. The March 2015 sampling event was the first in which newly
constructed Outfall # 2 was used to collect a representative sample. It is possible the elevated
values listed above are due, in part, to sampling of the new location.
Outfall # 2 was within the benchmark range for the following criteria:
• pH
• Non -polar oil and grease/total petroleum hydrocarbons
• Total toxic organics
In accordance with the GP, the Site is currently 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 or within 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).
If, during the duration of the GP, exceedances occur for anyspecific parameter on-four•occasions,
Galvan must contact the DWQ Regional Supervisor w' h n 30 days of receipt of the fourth result`
SubsequeriNoq i;ements may include a change in monitoring re ppl+e
Cindividual permit, in?;ation of stormwater controls, additional monitoring locations, or
odifications to the Si in order to qualify for a No Exposure Exclusion.

` 1y7onthiy 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.
3 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, Table 3 identifying the especially sensitive receiving water classifications where the more protective benchmark applies.
' Total Toxic Organics sampling is applicable only for those facilities which perform rnetaf finishing operations, manufacture semiconductors, manufacture
electronic crystals, or manufacture cathode ray tubes. For purposes of this permit the definition of Totai 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 crystai manufacture use the definition as found in 40 CFR 469.22; and for cathode ray

may be waived. The solvent management plan ;hall include a list of the total toxic organic compounds used and the other elements listed in the Genera!
Permit. For those facilities electing to employ the 77O monitoring waiver, the discharger shall sign the following certification statement:
"cased upon my inquiry of the person or persons •dlrectly responsible for managing compliance with the permit monitoring requirement for total toxic organics
(70), i certify that to the best of my'rtnowledge and belief, no dumping of concentrated toxic organics into the stormwateror areas which are exposed to rainfall or
5tormwater runoff has occurred since filing the last discharge monitoring report. 1 further certify that this facility is implementing the all the provisions of the
solvent management plan included in the Stormwater Pollution Prevention Plan."

FROM: Ed Watson via Andrew Pitner AHA
DATE: August 27, 2018
SUBJECT: Galvan Stormwater Permit NCG030099 and DWR Incident #7186
Background: Galvan Industries, Inc. submitted a Corrective Action Plan (CAP) that was approved by DWR
on April 8, 2013, to address impacts to waters of the State associated with their known groundwater
contamination. In 2013, regulatory oversight of the groundwater issue and their storm water permit
was provided by DWR, subsequent departmental reorganization has shifted storm water permitting
oversight to DEMLR.
The CAP, which has only been partially implemented to date, contains activities for source area
treatment via soil blending as well as significant storm water control conditions that are summarized
below:
1. Existing storm water catch basins upgrades near MW13 and MW14. The catch basins are
designed to reduce the rate of flow of storm water entering the site from properties along Hwy.
49 and to control storm water entering the Railroad ROW at the south end of the property.
These drains are linked together. The CAP requires these basins to be lined with limestone
boulders. Currently (Aug 2018), these basins contain igneous rip rap boulders.
2. Check dams are to be installed along the south end of the Galvan property to reduce the rate of
storm water flow from the southern boundary of the Galvan property into the railroad ROW.
One check dam is currently in place. Additional check dams may be necessary.
3. The CAP stipulated a total of 49,000 sq. ft. of Limestone gravel to be installed to the south and
immediately west of the galvanizing building. Currently, —75% of the limestone gravel has been
installed.
Outfall #2 was moved by the NCRR during the project that added an additional rail line along this stretch
of tracks in 2015. This project did result in some upgraded storm water controls along Galvan's
southern property lire.
The DWR-WQROS believes that an individual storm water permit, rather than a general permit, is more
appropriate for this facility based on the nature of the fabrication process and housekeeping employed
at the Galvan facility as well as the required implementation of specific storm water controls outlined in
the CAP.
Previous groundwater analytical data indicates elevated zinc and copper, iron, lead, sulfates, nickel,
manganese, chloride, cadmium and TDS present in groundwater samples. Similar constituents have also
been detected during storm water and surface water sampling events.
