Dear Mr Walker
John E Skvarla, III
Secretary
This letter is a follow-up to the letter dated 8 May 2014 sent after the Technical Assistance inspection conducted by Aana
Taylor Smith of the NC Division of Energy, Mineral, and Land Resources (DEMLR) on 7 May 2014 In that inspection, it was
decided that Columbiana Hi Tech would conduct a monthly sampling event for May 2014 If copper and zinc benchmarks
were exceeded at that event, Tier III would be triggered and DEMLR would assess options moving forward
All tiered response actions have been completed as required Columbiana Hi Tech has conducted extensive walkthroughs,
assessments of practices, and studies to determine potential sources of contaminants Samples of roof runoff were taken
and results were found to contain zinc at levels several times higher than the zinc benchmark for NCG030000 No other
clear sources of copper or zinc could be distinguished on the property However, there is significant potential for
contamination from off -site and upstream sources, particularly neighboring industries with connections to the Stormwater
system that drains from Columbiana Hi Tech's site
Based on recent analytical monitoring results and the tiered response actions completed by Columbiana Hi Tech, the
Division relieves you of the additional monitoring frequencies required in the Tiered Response section of this permit for
copper and zinc at Qutfalls 1 and 2 You must continue to monitor semi annually as required by the permit, but you will not
be required to institute monthly monitoring for any future exceedences of the copper and zinc parameters at Outfalls 1 and
2 Tiered response requirements still apply for all other parameters
We appreciate your efforts to comply with the stormwater permit and the proactive steps taken to identify and eliminate
potential sources of pollution No additional response to this letter is required, but please append this letter to your SPPP
to document that your facility has been relieved of monthly monitoring for the specified parameters If you have any
questions regarding the NCG030000 permit, please do not hesitate to contact Ms Taylor -Smith or me at [phone]

Dear Ms I aylor-Smith
Columbiana Hi Tech (CH I) has completed the Storm�,ti ater Run Of f sarnpltiig for the Month of
May as required by our Stotmwater Permit, Tiei II rc,qLill c,ments Samples From outfall I and 2
exceeded the Benchmaik (see attached Table 1 for iesults) This is the fourth consecutive sample
taken that has exceeded the Bench hark Limits fot Zinc and Copper (three required and one
extra) which retakes it also reportable under CHI's Tier III requirements
CHT took five exti a samples catching run off fiotn building 1 (2 samples), 2 3, and 4 All of
these samples contamcd zinc, and copper (sec, attached table for results) and ate believed to be
due to the galvanized roofing
The attached Table shows five consecutive samples taken over the period of 10/7/13 through
5/15/1 4 for outfall I and 2 and the additional samples taken from (lie roof down Spouts with all
showing high concentrations of Copper and Zinc. The samples on 10/7/13 were poor to CHI
receiving the Slormwatei Permit but are included for historical data
CHT has completed walk downs including one with Aana Tavloi-Smith of the Winston-Salem
Regional Office of the NC Division of Energy, Mineral and Land Resourc.e.s (DEMLR) and
could not identify a cause of the high leading other than possibly the i oof surfaces It is not
believed that the contaminates ate from below ground as soils samples were taken by AREVA
pi tot to purchase of CHT and the results wete acceptable at that tune No new processing that
would affect the samples has been implemented Sevetal improvement items have been
completed that would etthet have no affect of improve the quality of the Stormwatei Samples
The samples from the toot down spouts showed levels Of 71nc and copper which are a potential
cause of exceeding the benchmaiks
Based on CII I's diligence doling this process, CI IT is requesting relief trom the icquired "I lei II
response of monthly samples and is if sponding to the Tiei III requirements for exceeding the

Dear Mr Walker
John E Skvarla, III
Secretary
Aana Taylor -Smith of the Winston-Salem Regional Office of the NC Division of Energy, Mineral, and Land
Resources (DEMLR) met with you to discuss tiered response requirements for the NCG030000 permit for metal
fabricators at the subject facility on 7 May 2014 Your assistance and cooperation, as well as that of Mr Matt
Willett, were greatly appreciated An inspection checklist is attached for your records and the findings are
summarized below
This facility is located at 1802 Fairfax Road in Greensboro, Guilford County, North Carolina Stormwater related to
industrial activity is discharged from that site to South Buffalo Creek, this segment of which is currently classified
as Class WS-IV, Nutrient Sensitive Waters, in the Cape Fear River Basin
Documentation & Monitorine Review
This meeting was held to assess compliance with NPDES General Stormwater Permit NCG030000 and to evaluate
drainage to the facility's two Stormwater Discharge Outfalls (SDOs) Monthly monitoring has been triggered by
consecutive exceedances of the copper and zinc benchmarks at both Outfalls 1 and 2 Please keep in mind that
benchmark exceedances are not limit violations or violations of permit conditions, however you are obligated to
follow the tiered response actions outlined in your permit Columbiana Hi Tech has been following the tiered
response actions and is therefore in compliance with the permit Both qualitative and analytical monitoring have
been completed as required The facility's Stormwater Pollution Prevention Plan (SPPP) contained all of the
required elements and is up to date and fully implemented
Site Review
The site was found to be orderly and well maintained Secondary containment is implemented as required, with
the exception of one kerosene tank, which will be removed next week by Safety-Kleen This facility has the
potential for off -site influences to affect runoff from the site Neighboring industries and streets have connections
to the stormwater system that drains from Columbiana Hi Tech's site Those connections are located upstream
from the outfalls and mix with stormwater from the site before being discharged at the outfalls

Tiered Response Requirements
Currently, monthly monitoring is required in response to two consecutive exceedances of the benchmark values
or range for any specific parameter at a specific SDO Columbiana Hi Tech has completed four sampling events
during which copper and zinc benchmarks were exceeded at both outfalls However, one of those sampling events
occurred on 7 October 2013, before the certificate of coverage under NCG030000 was issued on 15 October 2013
Columbiana Hi Tech will conduct a monthly sampling event for May 2014 If copper and zinc benchmarks are
exceeded at that event, Tier III will be triggered and DEMLR will assess options moving forward
Columbiana Hi Tech has completed tiered response actions as required by NCG030000 including walkthroughs,
assessments of practices, and studies to determine potential sources of stormwater contaminants Additional
testing is planned, which may include taking samples of water from roof surfaces during ram events Soil samples
have already been taken as part of the facility's due diligence program
Please notify this office in writing within 30 business days of receipt of sampling results if benchmark values are
exceeded for any outfall on four occasions, as required by NCG030000 Part If Section B
We appreciate your efforts to comply with the stormwater permit and the proactive steps taken to identify and
eliminate potential sources of pollution No additional response to this letter is required at this time Should you
have any questions regarding the NCG030000 permit or this letter, please do not hesitate to contact Ms Taylor -

Subject Unpermitted facilities in GSO
Hey Debbie,
Here's an update on the facilities you asked me to look into at the end of last month
Columbiana Hi -Tech this company submitted one application for No Exposure and one application for a NCG03
(metal fab) permit for its two locations in Greensboro Neither has been issued yet, but I will keep you in the
loop when they are The contact for both locations is Larry Walker, [phone] See below for details
a NCGNE0963 Facility name is Columbiana Hi Tech LLC, located at 204 S Westgate Dr Suite D
b NCG030639 Facility name is Columbiana Hi Tech LLC 2, located at 1802 Fairfax Rd
Box Board @ 8313 Triad Dr I Just got off the phone with the EHS guy, Jim Adams He was very interested in
getting a permit, and is currently reviewing whether the facility would qualify for No Exposure His phone
number is [phone] x1068 and email address is tadams@boxboardproducts com Their SIC code (2653)
qualifies them for an NCG05 permit for printing, etc , but they will apply for No Exposure if possible
PBM @ 415 Westcliff Rd This facility does digital commercial printing services They are most likely going to
qualify for an NCG05 as well The EHS guy there, Johnny, is currently reviewing their processes for me to
determine their SIC code I suspect it's 2759 If that's the case, I'll have them apply for NCG05 The phone
number at the Greensboro location is [phone]
Thanks again for the heads -up, and I will pass along updates as they become available I will probably go review
Columbiana's No Exposure next week, if you want to come with? O

Subject RE Heads Up
Gotcha
So, speaking of places that probably don't have a permit but might should here are three in question that have come
up one way or another for us Maybe they don't need permits, but they seems a little suspect for various reasons
Columbiana Hi Tech, 1802 Fairfax Road, http //www chtnuclear com/
I went on a call here via a request by Corey and a complaint to the state Turns out it was nothing, and they seem to be
in pretty good shape in general I asked Mike about whether it should be permitted, and I'm not where that left off
Box Board, 8313 Triad Drive, http //www boxboa rd products com/
I inspect their BMPs, and it never occurred to me that maybe they should be permitted until my contact there asked me
if they had a permit number I couldn't quite figure out where they fit in the mix, so I gave him Mike's info so he could
contact the state I'm not sure if he ever did that but am thinking no
PBM Graphics, 415 Westchff Rd , http //pbmgraphics com/
saw this while out in the field ---towers and such behind the building This website notes only a Durham location, and
looking at the aerial in GIS I'm guessing this is a relatively new location
Sorry to give you more work to do If you find out anything about these in the future, let me know
And thanks for the birthday wishes I love getting a year younger every year (-)

Subject RE Heads Up
Excellent' I think they're lust applying for an NE certification right off the bat We don't have them listed under any
general or individual SW permit Sometimes that does happen they must have had some kind of internal EHS audit or
something and found out they should've had one I will definitely forward you any additional info I get when they
receive their No Exposure Certification
By the way — happy birthday 10

2 0 .INTRODUCTION
The Water Quality Act of 1987 (Section 402(p)) requires that operators of
certain facilities which discharge stormwater associated with industrial
activity apply for a permit to conduct such activities Columbiana Hi
Tech, LLC (CHT) is covered under North Carolina General Permit No
NCG030000 The facility applied for a Certificate of Coverage in March
2013 The North Carolina Department of Environment and Natural
Resources (DENR) has therefore been delegated authority to unplement
and manage North Carolina's stormwater grogram Part II, Section A of
the permit requires that the permittee shall develop a Stormwater
Pollution Prevention Plan (SPPP) in an effort to reduce pollutant
discharge to surface waters
27 FACILFTYLOCAT70N

23 FACILITY OPERATIONS
I'he Greensboro facility employs apprommately 84 full-time employees
CHT operates two shifts Monday through I'hursday, but frequently
includes a Friday shift to complete production requirements
CHI' is a metal fabricator for specialty products used in the transport and
storage of nuclear fuel rods Stainless steel, carbon steel, and alummum
compose the majority of raw metal stock used in the production process
Fabrication processes include saw cutting, drilling, machining and
bending the metal Some products are sent to CRT's off -site locations for
additional fabrication and assembly Welding takes place using assorted
tecluuques, including metal inert gas (MIG), tungsten inert gas (TIG),
submerged arc, spot, and plasma
Additional operations include media blasting and painting Media
blasting takes place on -site inside Building 4 within a self-contained booth
using either silica glass (about 10% of the total blasting effort - silica glass
beads are used exclusively on stainless steel) or garnet beads (about 90%
of the total blasting effort-- used on carbon steel and aluminum) Painting
is conducted in a paint booth at the western portion of Building 3 New
paint (that is either a two-part or three-part epoxy) is stored in a srnall
detached trailer located adjacent to the north side of Building 3
Ancillary activities at the site include quality control testing of products
using penetrants, egwpinent maintenance, and administrative functions
The facility's industrial operations are classified under NAICS Code
332999, All Other Miscellaneous Fabrtcated Metal Products and SIC 3499,
Fabricated Metal Products, Not Othenij se Classified
24 FACILITY DRAINAGE
The property slopes from east to west, with elevations ranging from
approximately 870 feet above mean sea level (AMSL) to 850 feet AMSL A
tributary of South Buffalo Creek is located approximately 780 feet west-
northwest of the western property boundary The property drains west
towaids South Buffalo Creek Several stormwater catch basins, or drop
i-ets, axe located around the buildings, which are connected to
underground piping that discharge to two outfalls west of the fence line
All industrial storrnwater at the facility drains via these two outfalls
designated as Outfall 1 and Outfall 2 Outfall 1 is located at the northwest
property fence line OutfalI 2 is located at the southwest property line,

Figure 1 of Appendix A demonsirates the location of the Columbiana Hi
Tech facility on a USGS quadrangle map
3 1 1 1 Iota[ Maximum Daily Load (TMDL)
According to North Carolina's 303(d) List, South Buffalo Creek is
considered unpaired water for ecological/biological integrity at station 16-
11-14-2a In addition, total maximum daily loads (TMDLs) have been
established by North Carolina Division of Water Quality for South Buffalo
Creek for fluoride, cyanide, and seleruum At this time, the facility is not
required to perform additional actions in regards to the established
TMDI s for South Buffalo Creek because the facility does not have
fluoride, cyanide, or selennuin readily exposed to slornnwater and
therefore does not have reasonable potential to contribute these
contaminants to stormwater
312 Description of Storage, Loading, Dust Generating, and Waste Disposal
Practices [Part II, Section A 1 b j

containers) are received via tractor trailer at Btuldmg I Loading and
unloading activities are monitored by a qualified CHT employee
Loading and receiving areas are shown on Figure 2 of Appendix A
3 1 2 3 Dust or Particulate Gepieration
A dust collector is used to control dust (particulate matter) from the blast
booth located in Building 4 Since the dust collection system vents back
inside Building 4, dust is not expected to be exposed to storm water CHT
inspects the area around the dust collector for visible signs of dust:
3 1 2 4 Waste Disposal Practices
All waste generated at the facility is segregated into groups General trash
is collected in a closed metal dumpster located at the northwest comer of
the property and an open dumpster located near the eastern property line
Three open -top metal shavings dumpsters are located at the northwest
corner of the property SIudge from the water let and spent shot blast are
stored in a dumpster located under a canopy south of Building 1 Special
wastes, including oily rags are collected inside in closed drums and sent

315 Non-Storniwater Discharge Certification [Part H, Section A 7 e 3
A non-stormwater certification foi m is presented uz Appendix E The
stormwater certification is required to be completed and re -certified on an
annual basis As part of the cei tification process, a knowledgeable CHT
employee must walk the property and inspect all stormwater
conveyances, catch basins, drop inlets, and the two outfalls for the
presence, or evidence of, non-stormwater discharges Typically, these
"non-stormwater" discharges can include items such as boiler blowdolAM,
oil/water separator overflow, wash waters, water let discharges, air
compressor condensate, etc
32 STORMWATERMANAGEMENTPLAN[PARTH,SEC-BONA 21
This plan has been developed to minimize the possibility of an unplanned
sudden or non -sudden release of oil or other substance into surface water
that could threaten human health, and/or the environment The plan
includes a prediction of the direction, late of flow, and total quantity of
material released which could result from an equipment failure, tank
overflow, rapture, leak or spill, fire or explosion
Spills inside the building would generally be contained withuz the
building Spills outside of the builduigs or spills that could leave any of
the buildings are addressed below Spill kits have been placed in these
areas to enable facility personnel to contain the spill before it leaves the
facility property
If a spill or leak were to occur in any outside area, the material would
remain in the general area of the spill CIean up of the released material
would be accomplished using sorbent materials When spent, these
sorbent materials would be disposed of in accordance with appiopriate
regulations
3 2 1 Feasibihhj Study [Part IT, Section A 2 al
Due to the size, the nature of the operations, and the manufacturing
processes at the CHT facility, it is technically ir►feasible and cost
prohibitive to eliminate stormwater exposure to all process materials Tide
facility will investigate the feasibility of
• providing secondary containment for the outside ASTs (kerosene and
diesel fuel)
• Covering the open -top metal shavings dumpsters,
E{iM NC. INC 3-4 1lr�7i

• reducing the amount of materials stored outside
the facility will review the feasibility of diverting the stormwater run-on
from areas of potential contamination and methods of operations/storage
practices to reduce exposure of materials to stormwater on an annual
basis 11us review is documented on the Annual Review form in
Appendix B
322 Secondary Containment Schedule [Part 11, Section A 2 b]

containment A 200-gallon diesel above ground storage tank, mounted on
a portable trailer is typically stationed south of Building 3 Me diesel tank
is not equipped with secondary containment. The facility will investigate
the feasibility of providing secondary containment for these storage tanks
and will develop an appropriate schedule for completion
The facility does not store and SARA 313 water priority cheirucals outside
323 BMP Summary [Part 11, Section A 2 c]
The facility has provided structural and non-structural measures or
practices to reduce the amount of pollution entering surface waters
Structural best management practices employed at the CHI facility
include providing canopies over the sludge dumpster and the drums
containing methyl ethyl ketone and denatui ed alcohol Catch basins are
provided to improve stormwater flow throughout the facility Non-
structural best management practices include providing rip iap at both
stormwater outfalls to reduce erosion, semi-annual stormwater
inspections, monitoring loading/ unloading operations, and good
housekeeping procedures
It is recommended that the facility investigate the feasibility of covering
all dumpsters and providing secondary containment for the above ground
storage tanks (see Sections 3 21 and 3 2 2)
Best management practices are reviewed on an annual bases

certification process, a knowledgeable CHT employee must walk
the property and inspect all storrnwatei conveyances, catch basins,
drop inlets, and the two outfalls for the presence, or evidence of,
non-stormwater discharges Typically, these "non-stormwater"
discharges can include items such as boiler blowdown, oil/water
separator overflow, wash waters, water let discharges, air
compressor condensate, etc The results of the inspection and the
subsequent certification should be recorded and maintained within
this Plan This monitonng report meets requirements contained in
Part Il, Section A 8
The SPPP shall be reviewed and updated on an annual basis, and
