Subject: RE. Update
Good morning Aana,
It was good to finally meet you yesterday after many emails; I hope you had time to look around while you were in
Welcome it's a nice little town. Thanks for the letter it takes a lot off my shoulders with management, sometimes they don't
understand all the work we go through trying to keep compliant and the environment clean as possible. Thanks for
explaining some of the details about gathering and sending stormwater samples to the lab without using other services,
that's going to be a great cost savings that I can use to improve our facility.
If you're ever in Welcome again doing any inspections let me know and we will try to do lunch.
Thanks again for your help
Joe

Certificate of Coverage NCG030613
MATCOR Metal Fabrication
Davidson County
Dear Mr. Edwards:
Aana Taylor -Smith of the Winston-Salem Regional Office of the NC Division of Energy, Mineral, and Land
Resources (DEMLR) conducted a compliance evaluation inspection at the subject facility on 30 December 2013.
Your assistance and cooperation during the inspection were greatly appreciated. An inspection checklist is
attached for your records and the inspection findings are summarized below.
This facility is located at 835 Salem Road in Welcome, Davidson County, North Carolina. Stormwater related to
industrial activity is discharged from the site to Swearing Creek, which is currently classified as Class C Waters, in
the Yadkin -Pee Dee River Basin.
Documentation & Monitoring Review
The facility's Stormwater Pollution Prevention Plan (SPPP) contains all of the required elements and is up to date
and fully implemented. Both qualitative and analytical monitoring have been completed as required. The facility
has two Stormwater Discharge Outfalls (SDOs) that discharge stormwater related to industrial activity. A tiered
response has been instituted for both SDOs at this time.
Sample results from Outfalls 001 and 002 exceeded benchmarks for copper and zinc results to trigger a tiered
response. In all cases, MATCOR Metal Fabrication has complied with permit requirements to increase sampling,
identify potential sources of pollution, and attempt to eliminate them. The facility is in compliance at this time.
Site Review
The facility is clean and well -maintained. No vehicle maintenance takes place on site. Both outfalls were inspected
and found to be in good order. No evidence of erosion or instability at the SDOs was observed and the receiving
stream was free of pollution indicators.

Tiered Response Re uirements
Currently, monthly monitoring is required in response -to consecutive exceedences of the benchmark values or
range for any specific parameter at a specific SDO. MATCOR Metal Fabrication has completed monthly monitoring
for all outfalls as well as conducting extensive studies to identify and eliminate potential sources of
contamination. Exceedences of copper and zinc benchmarks have continued at both.outfalls despite the facility's
proactive attempts to identify and eliminate any source of pollutants.
At this time, the Division concurs that more frequent monitoring at this site would be ineffective. The Division
relieves you of the additional monitoring frequencies required in the Tiered Response section of this permit for
the parameters specified. 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 copper and zinc parameters at Outfalls
001 and 002. 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 requirements for the
specified parameters. Should you have any questions regarding the NCG030000 permit or this inspection, please
do not hesitate to contact Ms. Taylor -Smith or me at [phone].

Welcome, NC 27374
Dear Permittee:
NCDENR
Department of Environment and Natural Resources
Division of Water Quality
Charles Wakild, P. E.
Director
December 4, 2012
Dee Freeman
Secretary
Subject: NPDES Stormwater Permit Coverage Renewal
Matcor Metal Fabrication
CDC Number NCG030613
Davidson County
In response to your renewal application for continued coverage under stormwater General Permit NCG030000
the Division of Water Quality (DWQ) is forwarding herewith the reissued General Permit. This permit is
reissued pursuant to the requirements of North Carolina General Statute 143-215.1 and the Memorandum of
Agreement between the state of North Carolina and the U.S. Environmental Protection Agency, dated October
15, 2007 (or as subsequently amended).
The following information is included with your permit package:
• A new Certificate of Coverage (CDC)
• A copy of General Permit NCG030000
• A copy of the Technical Bulletin for the General Permit
• Two copies of the Discharge Monitoring Report (DMR) Form
• Two copies of the Qualitative Monitoring Report Form
The General Permit authorizes discharges of stormwater, and it specifies your obligations for discharge
controls, management, monitoring, and record keeping. Please review the new permit to familiarize yourself
with all the changes in the reissued permit. Your facility has six (6) months from the time of receipt of the
permit to update your current SPPP to reflect all new permit requirements.
The first sample period of your permit begins January 1, 2013. Your facility must sample a "measureable
storm event" beginning during the periods beginning January 1 and July 1 of every year (or, if applicable,
report "No Flow," as outlined in Part III, Section E). Also, please note that Tier 3 Actions in Part II of your
permit are triggered by benchmark exceedances on four occasions beginning on the effective date of this
permit and do not count prior exceedances.
The more significant changes in the General Permit since your last CDC was issued are noted either in the
Draft Permit Fact Sheet that accompanied the public notice (http://portal.ncdenr.org/web/wct/ws/su/current-
notices), or in the Response to Comments / Summary of Changes and Technical Bulletin documents that are
posted on the Stormwater Permitting Unit's website with the new General Permit. Please visit
http://portal.ncdenr.org/web/wq/ws/su/npdessw (click on 'General Permits' tab) to review that information
for your specific General Permit carefully.

Some of the changes include:
Part ll:
• Section A: The Stormwater Pollution Prevention Plan (SPPP) section, if applicable, has been updated
to the most current language of our permits. Additional conditions for specific industry sectors have
been added to the SPPP requirements in some cases.
• Sections B, C: Failure to perform analytical stormwater monitoring may result in the Division requiring
that the permittee begin a monthly sampling scheme.
• Sections B, C: A lower TSS benchmark of 50 mg/I for HQW, ORW, PNA and Tr Waters applies to these
more sensitive waters.
• Sections B, C. The monitoring parameter Oil & Grease (O&G) has been replaced by the parameter
Total Petroleum Hydrocarbons (TPH) for vehicle maintenance areas, and in some cases, other
analytical monitoring requirements.
• Sections B, C, D: Inability to sample due to adverse weather must be recorded in the SPPP, or in
separate on -site records if your General Permit does not require an SPPP. Adverse weather is defined
in the "Definitions" section of the permit.
• Sections 8, C: The term "Representative Storm Event" has been replaced by "Measurable Storm
Event." A measurable storm event is defined in the permit.
• Section D: If the permittee fails to respond effectively to problems identified by qualitative
monitoring, DWQ may require the permittee to perform corrective action.
Please review Parts III and IV to understand the Standard Conditions of your new NPDES General Permit,
including Compliance and Liability, Reporting, Monitoring and Records requirements; Operation and
Maintenance obligations; and Definitions. Please note that all samples analyzed in accordance with the terms
of this permit must be submitted to the Division on Discharge Monitoring Report (DMR) forms available on
the Stormwater Permitting Unit's website above. DMR forms must be delivered to the Division no later than
30 days from the date the facility receives the sampling results from the laboratory. Also note that existing
permittees do not need to submit a renewal request prior to expiration unless directed by the Division.
Your coverage under the General Permit is transferable only through the specific action of DWQ. This permit
does not affect the legal requirements to obtain other permits which may be required by DENR, nor does it
relieve the permittee from responsibility for compliance with any other applicable federal, state, or local law,
rule, standard, ordinance, order, judgment, or decree. if you have any questions regarding this permit
package, please contact the Division's Stormwater Permitting Unit at [phone].

Dear Mr. Edwards:
Dee Freeman
Secretary
A Compliance Evaluation Inspection was performed at MATCOR Metal Fabrication in Welcome, North
Carolina on November 12012 by Jenifer Carter of the Winston-Salem Regional Office. You were present for the
inspection. The purpose of the inspections was to review compliance with the National Pollutant Discharge
Elimination System (NPDES) General Stormwater Permit. The following are the findings from the subject
inspection:
+ MATCOR was first issued the subject permit on October 21, 2011. The cover letter, nor the permit cover page
sent to MATCOR, listed an expiration date. Understandingly, this led you to assume that the 5-year permit
expired 5 years from the date issued. In actuality, the permit expired on October 31, 2012, as all general
stormwater permits of this type expire at the same time.
You were provided a renewal application form after the inspection. Please submit the application as soon as
possible. If for some reason your new renewed permit also fails to list an expiration date, please call our office
to find out what it is. For future reference, renewal applications must be submitted at least 180 days prior to the
permit's expiration.
+ A Stormwater Pollution Prevention Plan (SPPP) has been properly developed and implemented as written.
• Qualitative monitoring has been conducted as required and recorded as required.
The Division greatly appreciates your efforts to maintain compliance. Should you have any questions, please
contact Jenifer Carter at [phone].

Permit: NCG030613 Owner - Facility: Matcor Metal Fabrication
Inspection Date: 11/06/2012 Inspection Type: Compliance Evaluation Reason for Visit: Routine
Inspection Summary:
Matcor was first issued this permit on October 21, 2011. The cover letter, nor the permit cover page sent to him, listed an
expiration date, so Mr. Edwards assumed that the permit was good for 5 years from issuance. Because of the lack of
information from DWQ, a renewal application was not submitted prior to the October 31, 2012 expiration. A renewal
application form was provided to Mr. Edwards the day of the inspection,.and he will submit it as soon as possible. There
have been no significant changes since the permit was first issued.
The SPPP was complete and implemented fully and properly. TTO Certification statements were available for review, as
they are required for the Town of Lexington's pretreatment program. They had a Toxic Organic Management Plan
(TOMP), which is the pretreatment program's equivalent of a Sludge Ma nag ement/S pill Plan.
Qualitative montioring has been done as required, sith no problems noted.
The site would not qualify for No Exposure due to the uncovered storage of pallets and finished product outside.

Please go ahead and issue the permit. I have been working with them on the creation of their SPPP, and have dealt with
them in the pretreatment realm as they have a pretreatment permit with the city. They seem to want to do what they
need to do to be in compliance.
Thanks!

I'm assuming you mean a Spill Control Plan. If so, that would serve as a component of the SPPP, as it relates to chemical
inventory and BMPs for controlling spills. You would still need to address the other aspects of the plan -not related to
that, like staff training and monitoring.

Joe,
I've attached a pdf file with photocopies of various business cards. Many of these have been gathered from folks doing
stream restorations, but many of them also do create SPPPs.
That being said, I think they sometimes overcharge for what they do, often just cutting and pasting from other plans.
have seen some decent plans done by students from environmental programs, so that is another way to go. I would be
happy to review what you end up with, if that helps.

Good luck!

Joe,
First, you are right that all streams are 303(d) listed for Mercury. I always forget that.
And you are also correct.., the site drains to an unnamed tributary (UT) to Swearing Creek, so it takes on Swearing
Creek's classification (Class C) and listing.
In addition to being listed for Mercury, it is 303(d) listed for Ecological/biological Integrity (fish communities). There is a
statewide TMDL for the mercury listing, but no TMDL has been developed for the Ecological/biological Integrity listing.
Hope that helps. Let me know if you have any other questions.

Actually, not all streams are 303(d) listed. If you let me know which named stream the site drains to, I can look it up for
you, including TMDL info, if necessary. If you don't know which stream, give me the site address and I'll look at our
USGS maps and figure it out.
I'm headed out of the office for the morning, but can respond after lunch.

Pamela,
I'm sorry you had to go through so many people to get to me. I wish I could say that was unusual.
Here is a link to General Stormwater Permit Info:
http://Portal.ncdenr.org/web/``wq/_ws/`­
_su/npdessw
Once on the site, click on the blue `General Permits' tab near the top, which will pull up a list of permits and related
documents.

Scroll down to NCG030000. That is the one you will be dealing with. To the right of that, you will see links to the permit
text, the NOI (application), and a technical bulletin (two page summary of the permit requirements).
Just follow the instructions on the NOI, and let me know if you need any help filling it out. When you get the permit, I
will also receive notice from the central office in Raleigh. I am the one imposing the 6 months deadline for creating the
SPPP, not Raleigh, so their letter won't say anything about that. Just know that you have 6 months from the date your
application is approved.
This is a general permit, meaning that everyone manufacturing metal products has the same exact permit, though you
will be assigned a unique number called the Certificate of Coverage (NCG03XXXX). This permit expires every 5 years,
with the current permit cycle expiring on October 31, 2012. Look at Part III Page 3 for renewal information. The Raleigh
office has always been good about sending reminders, but just know that you have to request renewal at least 180 days
prior to the expiration date.
Do not hesitate to contact me with any and all questions.

Matcor Metal Fabrication
Semi-annual Stormwater Discharge Project
J. Edwards EHS Coordinator 10-30-2013
Introduction
North Carolina Department of Environment and Natural Resources (NCDENR) require Matcor
Metal Fabrication to have a Stormwater Permit. Within the permit it specifies our obligations for
discharge controls, management, monitoring, and record keeping. Part of our compliance
requires a semi-annual Discharge Outfall Qualitative Monitoring Report,
O Waters Edge Environmental, LLC provided Matcor this service for Period two of 2013
(July- Dec.). Based on the these results, we have exceedances for the following:
• Outfall001
O Exceedance for copper which was detected at 0.021 rng/L verses a
benchmark at 0.007mg/L.
O Exceedance for zinc which was detected at 0.42 mg/L verses a benchmark
at 0.067mg/L
• Outfall002
O Exceedance for zinc which was detected at 0.38 mg/L verses a benchmark
at 0.067mg/L
These exceedances have placed Matcor in the Tier 2 range of a 3 Tiered program according to
the guidelines of the Stormwater Permit. If zinc and copper are not brought down to the excepted
benchmark with the next stonmwater sampling the severity will graduate to Tier 3. These Tiers
can be referenced in the Stormwater Permit package.
Actions
Step 1. Review SPPP and conduct a walk through to see if we are following measures laid out in
the plan.
Step 2. Create and complete an inspection worksheet and record the observations for possible
zinc and copper contaminations that could keep these out of our stormwater discharge.
Step 3. Implement action items that are created during review and inspections.
Step 4. Make revisions to the SPPP required by the stormwater permit.
Step 5. Schedule Waters Edge Environmental to collect grab samples after a measurable
storm event to again measure the zinc and copper levels in our stormwater discharge

5. Spill prevention measures (such as covered areas over exposed materials, operations indoors
where suitable)
Observations of spill measures in place: All fabricating operations are performed inside. Empt
steel drums that are stored outside are covered. All other containers taken outside are orieinal
lids. Most of the customer containers/bins stored outside are stored upside down so they will not
collect water.
New observation for October 2013:
o Increased amount of customer shipping containers from the July 2013
inspection
6. Chain -link fence
a. Material
b. Length
c. Location within facility or on perimeter, over vegetation or over pavement

the copper limit in the stormwater.
5. Check with pallet supplier for wood preservatives or pesticides used to treat pallets or
containers on site. Pallet Resources supplies our pallets, they stated that no chemicals of any kind
are used to treat pallets. PRNIC uses the approved heat treat method which is safe to the
employees and to the environment.

Stormwater Inspection Roof Pictures
Exhaust Vent Enclosures - These range from having very little rust to some have a great deal.
These could be a source of the zinc. Painting the ones in question
may help.
(Partition and Ridge Caps - Same as above
Paint on the roof - Parts of the roof has been painted in the past or metal was painted when
purchased Some of the white roof paint has zinc oxide in it. of course we
don't know about this paint When the paint gets old it starts to oxidize,
the bottom of our shoes were white with transfer when we were conducting
our inspection. Not knowing if the paint had zinc oxide in it to begin
with, it may not be a good idea to repaint because of the cost.
We should try the more economical solutions first. Ultratech makes a catch
basin insert that traps zinc and copper along with other metals that get
released into the stormwater
Galvanized roof material - 2 additional samples were taken from 2 gutter downspouts in October
the results were, roof 1 sample at 1.9mg/L Zinc, roof 2 sample at 0.23 mg/L Zinc. The benchmark
is 0 067mg/L.

Stormwater Inspection Parking Lot Pictures
The inspection shows that just about every parking spot has some amount of oil/fluid buildup.
Over time dust builds up in these areas then the rain and washes the dust and material that it
has absorbed into the stormwater. Waters Edge Environmental representative stated that he
didn't think our exceedances were coming from the parking lot.

This picture was taken from the BBQ
restaurant property looking towards our
plant. Looks like some erosion has
occurred coming onto our property but
the BBQ restaurant don't have much of
a paved parking lot.

Inspection
• 1 am in the process of talking with NC DENR/ DEACS and they are reviewing the
infonnation about our exceedances.
+ I am double checking all the different departments here to make sure we are
following the SPPP.
• We have a finished hydraulic/fuel tank area that performs a leak test on the tanks
for Caterpillar. This tank consists of only water that the fabricated tanks are
dipped into under air pressure to insure that they are no leaks. When it's time for
these tanks to be dumped and fresh water added it is routed outside. I have
notified maintenance to have this water re-routed to our pre-treatment tanks and
then sent to Lexington City sewer along with our other wastewater for a
preventative measure. (Completed on I 1-06-13)
At the recommendation of DEACS I'm going inspect the property on our west
side to see if we're getting any run off from those properties which consist of a
Barbecue Restaurant and Veterinarian Clinic, both of which have large paved
parking lots which may contribute to our Copper. (Completed and sent to
DEACS)
Also at the recommendation of DEACS send waters samples to a different
certified lab to see if the same results are found. Our current lab is Pace
Analytical; I am in contact with Prism Laboratories for pricing. I am also trying to
find out what steps need to taken for us to collect the samples ourselves and send
them in to see it is more cost effective.
