Subject: Galvan Industries draft permit NCS000597
Good afternoon,
I am following up on our meeting concerning the draft permit NCS000597 for Galvan Industries. After speaking with
other DEMLR staff, an individual permit is required as the general permit does not have the scope of monitoring needed
for the site. The proposed individual permit has monitoring for monthly oil usage as well as special conditions for zinc
management and metal removing SCMs. The NCG03 general permit does not have this monitoring or conditions
required.
The Mooresville Regional Office will be in charge of determining whether representative outfall status can be granted
for SW002. That is an independent process from the issuance of this permit, so the permit will not be held for that
decision. If you have any further comments on this permit, please submit them by April 27, 2022. 1 will then give the
permit to my supervisor for final review and approval.
Thank you,

April 16, 2021
NCDEMLR Stormwater Program responses to Galvan Industries' comments on Draft
Permit NCS000597 received April 9, 2021:
1. Galvan acknowledges and accepts the requirement to collect analytical and qualitative
monitoring samples during "measurable storm events," indicating that actual discharge has
occurred, as defined in Part J of the draft permit. Related to this requirement, in Section D-3,
outfall monitoring shall begin at least 48 hours after the previous measurable storm event
(sub -parts (a) and (d)), however, the definition states 72-hours. Galvan asks that NCDEQ
clarify the required minimum frequency between measurable storm events.
The 48-hour requirement in Section D-3 was an error. The requirement is 72 hours. This will be
corrected in the draft permit before it is sent to public notice.
2. Galvan acknowledges that Section B-10 (Conditions for Zinc Management) and Section B-11
(Metal Removing SCMs) are new requirements for this site and will result in an updated
SWPPP from the current version.
This is acknowledged. Please be sure to read through the requirements and pay particular
attention to the required timelines.
3. Galvan has noted the following changes to quantitative monitoring:
• The previous version of NCG030000 contained the requirement for analysis of O&G
using EPA Method 1664 (SGT-HEM) with a benchmark of 15 mg/L. Galvan will review
average monthly oil usage onsite and implement analysis of O&G/TPH only if average
usage exceeds 55 gallons per month.
• The draft permit now requires analysis for chemical oxygen demand (COD).
• The copper parameter code for reporting has changed from 01119 to C0665 and the
benchmark has changed from 0.010mg/L to 0.2 mg/L.
• The zinc parameter code for reporting has changed from 01094 to 01092, but the
benchmark has not changed.
• Total toxic organics (TTO) testing will no longer be required under the draft permit.
When initially discussed with Zahid Khan in 2019, Galvan understood that an advantage of
operating under an Individual Permit is that NCDEQ can establish site -specific benchmark
criteria that consider operations at the site; however, the benchmark for the most commonly
used parameter onsite (zinc) has not changed in the draft permit. Was consideration given to
zinc use onsite prior to setting the zinc benchmark in the draft IP?
Consideration was given to zinc use onsite prior to drafting the individual permit, which is the
reason for the Conditions for Zinc Management and Metal Removing SCMs. However, all general
and individual permits have the same benchmarks. The rationale for the zinc benchmark is that
it is % of the Final Acute Value (FAV), which is the EPA's National Recommended Water Quality
Criteria (Acute) for dissolved zinc, calculated with assumed 25 mg/I hardness, and then
converted to total with EPA partition translator based on assumed 10 mg/I TSS. The benchmark

April 16, 2021
can't be changed, but the permittee is encouraged to work with the Regional Office to seek Tier
Relief, if applicable. Additionally, the copper benchmark was incorrectly written as 2 mg/L; it will
be corrected to 0.010 mg/L prior to public notice. I apologize for the confusion.
4. Can NCDEQ please clarify the requirements for submittal of DMRs under this permit? Per
Table 5, it appears that DMRs for sampling conducted between January 1, 2021 and March 30,
2021 have a submittal deadline of January 31, 2022?
Table 5 will be clarified to show that all DMRs are due 30 days after receiving all results,
regardless of whether paper DMRs or electronic DMRs are submitted. This table was a holdover
from a template that has since been updated. Please note that the registration deadline in
eDMR for individual permits was January 1, 2021. The permittee will be expected to register in
eDMR as soon as possible according to the instructions on the DEMLR Stormwater Program's
website here: deg.nc.gov/SW-eDMR.
Additional Questions:
1. May Galvan utilize historical / previous analytical monitoring data to meet Section D-1
(Required Baseline Sampling) or does NCDEQ request a new dataset to commence with this
permit?
No. Galvan will need to conduct quarterly monitoring according to the individual permit starting
on its effective date.
2. Prior to construction of the high-speed rail line in 2016, Galvan petitioned for and was
awarded representative outfall status for Outfall #2 on the site. During construction, Galvan
was concerned that earthwork and relocation of Outfall #2 approximately 50 feet east of its
former location would have a negative impact on stormwater quality at the outfall, and thus,
has sampled other outfalls onsite. Galvan would appreciate the opportunity to discuss with
NCDEQ the potential to move back to representative outfall status at Outfall #2.
James Moore with the Mooresville Regional Office will take on this topic.

Draft NPDES Stormwater Permit
Permit No. NCS000597
Galvan Industries
7315 Galvan Way, Cabarrus County, Harrisburg, NC
Dear Ms. Gamble,
On behalf of Galvan Industries, Inc. (Galvan), HDR Engineering, Inc. of the Carolinas
respectfully submits the following comments and questions for clarification to the draft
NPDES Stormwater Permit No. NCS000597 issued to Galvan on March 11, 2021. Based
upon our review of the draft permit, Galvan offers the following:
1. You are required to collect analytical and qualitative monitoring samples during
"measurable storm events" as defined in Part J. This term is different from the
"representative storm event" in earlier permits.
Galvan acknowledges and accepts the requirement to collect analytical and qualitative
monitoring samples during "measurable storm events," indicating that actual discharge
has occurred, as defined in Part J of the draft permit. Related to this requirement, in
Section D-3, outfall monitoring shall begin at least 48 hours after the previous
measurable storm event (sub -parts (a) and (d)), however, the definition states 72-
hours. Galvan asks that NCDEQ clarify the required minimum frequency between
measurable storm events.
2. Requirements for the Stormwater Pollution Prevention Plan (SWPPP) have been
updated in Part B.
Galvan acknowledges that Section B-10 (Conditions for Zinc Management) and
Section B-11 (Metal Removing SCMs) are new requirements for this site and will result
in an updated SWPPP from the current version.

3. Changes have been made to monitoring parameters and benchmarks for those
parameters. Stormwater benchmarks are not permit limits, but rather guidelines
for implementing the SWPPP. A benchmark exceedance is not a permit violation;
however, the permittee must respond to exceedances as directed in Part D.
Oil & Grease monitoring parameters have been revised as follows:
o Non -Polar Oil & Grease [EPA Method 1664 (SGT-HEM)] replaces Oil &
Grease/TPH. The benchmark for Non -polar Oil & Grease using this method is
15 mg/L. This requirement appears in all individual stormwater permits;
however, it only appliesto drainage areas where industrial activities use >55
gallons of oil, on average, per month. If the facility has any drainage areas in
which >55 gallons of oil are used during the permit cycle, the requirements
shall apply.
Galvan has noted the following changes to quantitative monitoring:
• The previous version of NCG030000 contained the requirement for analysis of
O&G using EPA Method 1664 (SGT-HEM) with a benchmark of 15 mg/L. Galvan
will review average monthly oil usage onsite and implement analysis of O&G/TPH
only if average usage exceeds 55 gallons per month.
• The draft permit now requires analysis for chemical oxygen demand (COD).
• The copper parameter code for reporting has changed from 01119 to C0665 and
the benchmark has changed from 0.010mg/L to 0.2 mg/L.
• The zinc parameter code for reporting has changed from 01094 to 01092, but the
benchmark has not changed.
• Total toxic organics (TTO) testing will no longer be required under the draft permit.
When initially discussed with Zahid Khan in 2019, Galvan understood that an
advantage of operating under an Individual Permit is that NCDEQ can establish site -
specific benchmark criteria that consider operations at the site; however, the
benchmark for the most commonly used parameter onsite (zinc) has not changed in
the draft permit. Was consideration given to zinc use onsite prior to setting the zinc
benchmark in the draft IP?
4. New requirements on reporting have been added in Part E to comply with federal
regulations requiring electronic submittal of discharge monitoring reports.
Additionally, this permit contains requirements forfuture reporting via eDMR
when the forthcoming eDMR internet application is finalized.

Can NCDEQ please clarify the requirements for submittal of DMRs under this permit?
Per Table 5, it appears that DMRs for sampling conducted between January 1, 2021
and March 30, 2021 have a submittal deadline of January 31, 2022?
Additional Questions:
May Galvan utilize historical / previous analytical monitoring data to meet Section D-1
(Required Baseline Sampling) or does NCDEQ request a new dataset to commence
with this permit?
2. Prior to construction of the high-speed rail line in 2016, Galvan petitioned forand was

Review for Permit Renewal — NCS000597
Galvan Industries - Harrisburg
Harrisburg, NC
Facility Activities and Process:
• SIC Code: 3479 — Coating, Engraving, and Allied Services, Not Elsewhere Classified
• According to the permit application, Galvan Industries, Inc. has operated a hot -dip galvanizing
facility since 1958 at this location. In 2005, a copper plating operation started at this facility as
well.
• The facility has three general operating areas: a galvanizing area, a blasting area, and a copper
plating area.
• Galvan stores raw steel on the western portion of the site, which is unpaved or gravel. Finished
product is temporarily stored east of the galvanizing building on concrete/asphalt.
• The facility generates iron sulfate/zinc sulfate heptahydrate crystal, which is packaged in super
sacks and stored under a roof to reduce potential for contact with stormwater.
• According to the permit application, Galvan has implemented BMPs to reduce stormwater
impacts, including scheduled product pickup to reduce dust migration, periodic street sweeping,
filter socks around stormwater outfa lls/in lets, and paving the area near the blast building.
o Galvan also removed 1,000 tons of loose dirt and replaced it with geotextile fabric re-
covered with limestone. There was a note in the inspection conducted 08-28-2018 by
James Moore that this limestone "cap" may increase TSS. Additionally, limestone check
dams and cobbles were installed to reduce sheet flow to SDO 2.
• The site is currently covered under NCG030099 but was required to apply for NPDES Individual
Industrial Stormwater Permit coverage because "the Director has determined that discharge
from [the] facility is a significant contributor of pollutants to surface waters" based on "site
inspections and a review of available discharge monitoring results," according to a letter dated
11-26-2018.
Monitoring Information:
• The facility appears to have kept consistent monitoring data. However, the facility frequently
reports 'No Discharge.' There was apparently no discharge from April 2019 to December 2020.
• The facility has been performing monthly monitoring in accordance with the Tier Response. The
facility is in Tier III. In April 2019 (the most recent DMR with a discharge reported), the facility
exceeded for TSS, Cu, and Zn.
There have been several exceedances of zinc and copper. The facility sent a letter to DEQ in
October 2014, regarding the zinc exceedances. The facility is in Tier III due to exceedances.
Surface Water Information:
• The receiving water, Back Creek (Index No. 13-17-7) is listed as impaired; exceeding criteria for
benthos (Fair; Nar, AL, FW).
• No TMDL could be found.

Threatened and Endangered Species:
• Carolina Creekshell Villosa vaughaniana (bivalve), State endangered;
• Tall larkspur Delphinium exaltatum (vascular plant), State endangered
Discussions with the Facility:
• Contact was made with the facility over phone on 01-26-2021.
Regional Office Information:
• Aana Gamble discussed the need for a zinc management plan and SCMs for metals (similar to
NCS000596 Wire -Bond) with James Moore from MRO in November 2020.

XII. NATURE OF BUSINESS (provide a brief description)
Since 1958, Galvan Industries, Inc. (Galvan) has operated a hot -dip galvanizing facility, and since 2005, a
copper plating facility at this location. Discharge of stormwater to an unnamed tributary of Back Creek is
regulated under NPDES General Permit No. NCG030000. The facility has three general operating areas: a
galvanizing area, a blasting area, and a copper plating area. An approximately 100-foot wide wooded area creates
a buffer between the western portion of the operating areas and offsite properties. Two of the four (Outfalls #
3 and 4) permitted stormwater discharge outfalls (SDOs) are located within the buffer area. The third SDO
(Outfall # 1) is located in the northeast corner of the site along Galvan Way (formerly Millbrock Road). A
fourth SDO (Outfall #2) is located within the Norfolk Southern railroad right-of-way south of the operating
arean Outfalln #5 and #6 are located in the central portion of the property and represent inlet junction boxes.

At approximately 6:30 AM on August 9, 2018, a surface spill of 8s sulfuric acid occurred in the acid recycling room of the main
galvanizing building. Approximately 832 pounds of sulfuric acid migrated east/northeast from the galvanizing building and was
intercepted by absorbent booms prior to discharge into any stormwater structures. The release occurred and migrated primarily
over impervious surfaces, with the exception of a small unpaved area (approximately 4 sq. ft.), which was subsequently
remediated by removal and disposal of impacted soil. On October 19, 2018, Galvan received a RCRA Inspection Report from the
CDEQ Division of Waste Management, Hazardous waste Section that summarized the spill and acknowledged that the response actions
were adequate and that no additional action was recommended.
