1 Monthly sampling (instead of semi-annual) must begin with the second consecutive benchmark exceedance for the same parameter at the same outfall.
Z For sampling periods with no discharge at any single outfall, you must still submit this discharge monitoring report with a checkmark here.
3The 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.
4 See General Permit, Table 3 identifying the especially sensitive receiving water classifications where the more protective benchmark applies.
5 Total Toxic Organics sampling is applicable only for those facilities which perform metal finishing operations, manufacture semiconductors, manufacture
electronic crystals, or manufacture cathode ray tubes. For purposes of this permit the definition of Total 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 crystal manufacture use the definition as found in 40 CFR 469.22; and for cathode ray
tube manufacture use the definition found in 40 CFR 469.31).

Facilitie3 that incorporate a solvent management plan into the Stormwater Pollution Prevention Plan may so certify, and the requirement for TTO monitoring
may be waived. The solvent management plan shall include a list of the total toxic organic compounds used and the other elements listed in the General
Permit. For those facilities electing to employ the TTO monitoring waiver, the discharger shall sign the following certification statement:
"Based upon my inquiry of the person or persons directly responsible for managing compliance with the permit monitoring requirement for total toxic organics
(TTO), I certify that to the best of my knowledge and belief, no dumping of concentrated toxic organics into the stormwater or areas which are exposed to rainfall or
stormwater runoff has occurred since filing the last discharge monitoring report. I further certify that this facility is implementing the all the provisions of the
solvent management plan included in the Stormwater Pollution Prevention Plan."

Subject:: Relief from Monthly Monitoring
Stormwater Permit # NCG030461
GEM Fabrication of North Carolina Inc.
Rowan County
Dear Mr. Smith:
ROY COOPER
Governor
MICHAEL S. REGAN
seere,ary
'I'RACY E. DAVIS
Director
We are in receipt of your July 17, 2017 letter requesting relief from monthly monitoring at the Ceveland facility. Based on the site
inspection May 4, 2017 and the information provided the facility is in compliance with the tiered response actions and other conditions of
the NCG030000 General Permit. Therefore, the Division is granting regulatory relief from the Tier responses. Upon receipt of this letter, the
subject facility may resume the permit specified semi-annual analytical monitoring for the remainder of the current permit term which
expires on October 31, 2017. This decision applies only to the copper and zinc benchmarks. A benchmark exceedance of any other
parameter listed in your permit will trigger the tiered responseactions as described in the general permit. When the new general permit is
issued you will need to review the new copper and zinc benchmarks and follow the applicable relief measures if required.
You must notify this office, in writing, within five business days if you become aware of any significant source of copper or zinc
at your facility that has the potential to be exposed to stormwater. The relief granted in this letter is contingent upon the current
industrial practices at GEM Fabrication of North Carolina Inc. If industrial practices change and copper or zinc does become a
significant stormwater exposure risk or significant zinc or copper values have been recorded during regular sampling events, then this
office reserves the right to withdraw this decision and reinstate the permit specified tiered response or other actions that may be
warranted by the new set of circumstances,
Please retain and append this letter to your Stormwater Pollution Prevention Plan (SPPP) or permit. If you have any
questions or comments concerning this letter, please contact me at 704-663-1699,
Sincerely,
30r_�J-ff_

' Monthly sampling (instead of semi-annual) must begin with the second consecutive benchmark exceedance for the same parameter at the same outfall.
2 For sampling periods with no discharge at any single outfall, you must still submit this discharge monitoring report with a checkmark here.
3The 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.
5 Total Toxic Organics sampling is applicable only for those facilities which perform metal finishing operations, manufacture semiconductors, manufacture
electronic crystals, or manufacture cathode ray tubes. For purposes of this permit the definition of Total 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 crystal manufacture use the definition as found in 40 CFR 469.22; and for cathode ray
tube manufacture use the definition found in 40 CFR 469.31).
Permit Date: 11/112012-10/31/2017 5WU-245, last revised 10/25/2012

Facilities that incorporate a solvent management plan into the Stormwater Pollution Prevention Plan may so certify, and the requirement for TTO monitoring
may be waived. The solvent management plan shall include a list of the total toxic organic compounds used and the other elements listed in the General
Permit. For those facilities electing to employ the TTO monitoring waiver, the discharger shall sign the following certification statement:
"Based upon my inquiry of the person or persons directly responsible for managing compliance with the permit monitoring requirement for total toxic organics
(TTO), I certify that to the best of my knowledge and belief, no dumping of concentrated toxic organics Into the stormwater or areas which are exposed to rainfall or
stormwater runoff has occurred since filing the last discharge monitoring report. I further certify that this facility is implementing the all the provisions of the
solvent management plan included in the Stormw Pollution Prevention Plan."

Mr. Moore,

I am writing this letter on behalf of Gem Fabrication, located in Cleveland, NC based off
of our meeting at the facility on May 0, 2017. Shamrock has been retained to help
maintain the storm water permit and aid in any way possible. Shamrock performed an
extensive storm water inspection at the beginning of our contract in October, 2015 and
found a few areas of concern that was soon corrected; however we continued to see
elevated Copper and Zinc levels_ Once it was determined that our areas of concern were
not the problem with our elevated levels we implemented barrier controls and carbon
booms at all storm water drains in hopes of reducing our Copper and Zinc levels; but to
no avail. Gem Fabrication has spent well over $50,000.00 dollars in an effort to be
compliant with our company mission statement and to be a good environmental steward.
We continue to exceed the benchmark standards, however; being relatively close to
compliance we are asking for help and possible return to the semi-annual sampling. We
are under the belief that we have a finished product (pipe) that has not been altered or
changed once received, therefore exempting us from the metal fabrication storm water
requirements.
We have noted the following:
• Tap water copper levels exceed our current benchmark requirements
• Added sand to try and help mitigate suspended solids
• Shamrock pressure washed all roof and appurtenances to help with any potential
runoff to outfall locations
• Built rainwater collection boxes to determine metal content
• Gem Fab has installed hay bales and carbon socks around drains to no avail
• Shamrock built a sediment basin to help settle any potential suspended solids
carry-over
• Shamrock installed floc logs specifically designed to remove Zinc and Copper
• Please find attached copies of inspections, analytical done in conjunction with
required sampling and countermeasures enacted
You will find attached a summary of sampling results beginning October, 2015.

i Monthly sampling (instead of semi-annual) must begin with the second consecutive benchmark exceedance for the same parameter at the same outfall.
Z For sampling periods with no discharge at any single outfall, you must still submit this discharge monitoring report with a checkmark here.
3The 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.
4 See General Permit, Table 3 identifying the especially sensitive receiving water classifications where the more protective benchmark applies.
5 Total Toxic Organics sampling is applicable only for those facilities which perform metal finishing operations, manufacture semiconductors, manufacture
electronic crystals, or manufacture cathode ray tubes. For purposes of this permit the definition of Total 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 crystal manufacture use the definition as found in 40 CFR 469.22; and for cathode ray
tube manufacture use the definition found in 40 CFR 469.31).
Permit Date: 11/1/2012-10/31/2017 SWU-245, last revised 10/25/2012

Facilities that incorporate a solvent management plan into the Stormwater Pollution Prevention Plan may so certify, and the requirement for TTO monitoring
may be waived. The solvent management plan shall include a list of the total toxic organic compounds used and the other elements listed in the General
Permit. For those facilities electing to employ the TTO monitoring waiver, the discharger shall sign the following certification statement:
"Based upon my inquiry of the person or persons directly responsible for managing compliance with the permit monitoring requirement for total toxic organics
(TTO), I certify that to the best of my knowledge and belief, no dumping of concentrated toxic organics into the Stormwater or areas which are exposed to rainfall or
stormwater runoff has occurred since filing the last discharge monitoring report. I further certify that this facility is implementing the all the provisions of the
solvent management plan included in the Stormwater Pollution evention Plan."

I Monthly sampling (instead of semi-annual) must begin with the second consecutive benchmark exceedance for the same parameter at the same outfall.
2 For sampling periods with no discharge at any single outfall, you must still submit this discharge monitoring report with a checkmark here.
a 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.
4 See General Permit, Table 3 identifying the especially sensitive receiving water classifications where the more protective benchmark applies.
5 Total Toxic Organics sampling is applicable only for those facilities which perform metal finishing operations, manufacture semiconductors, manufacture
electronic crystals, or manufacture cathode ray tubes. For purposes of this permit the definition of Total 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 crystal manufacture use the definition as found in 40 CFR 469.22; and for cathode ray
tube manufacture use the definition found in 40 CFR 469.31).
Permit Date:11/1/2012-10/31/2017 SWU-245, last revised 10/25/2012

Facilities that incorporate a solvent management plan into the Stormwater Pollution Prevention Plan may so certify, and the requirement for TTO monitoring
may be waived. The solvent management plan shall include a list of the total toxic organic compounds used and the other elements listed in the General
Permit. For those facilities electing to employ the TTO monitoring waiver, the discharger shall sign the following certification statement:
"Based upon my inquiry of the person or persons directly responsible for managing compliance with the permit monitoring requirement for total toxic organics
(Tro), I certify that to the best of my knowledge and belief, no dumping of concentrated toxic organics Into the stormwater or areas which are exposed to rainfall or
stormwater runoff has occurred since filing the last discharge monitoring report. I further certify that this facility is implementing the all the provisions of the
solvent management plan included In the Stormwater Pollution Prevention Plan."

' Monthly sampling (instead of semi-annual) must begin with the second conTeMe i chri _C excjedance for the same parameter at the same outfali.
2 For sampling periods with no discharge at any single outfall, you must still submit this discharge monitoring report with a checkmark here.
3The 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.
4 See General Permit, Table 3 identifying the especially sensitive receiving water classifications where the more protective benchmark applies.
5 Total Toxic Organics sampling is applicable only for those facilities which perform metal finishing operations, manufacture semiconductors, manufacture
electronic crystals, or manufacture cathode ray tubes. For purposes of this permit the definition of Total 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 crystal manufacture use the definition as found in 40 CFR 469.22; and for cathode ray
tube manufacture use the definition found in 40 CFR 469.31).

Permit. I -?those facilities electing to employ the TTO monitoring waiver, the discharger shall sign the following certification statement:
"Based upon my inquiry of the person or persons directly responsible for managing compliance with the permit monitoring requirement for total toxic organics
(7170),1 certify that to the best of my knowledge and belief, no dumping of concentrated toxic organics into the stormwater or areas which are exposed to rainfall or
stormwater runoff has occurred since riling the last discharge monitoring report. I further certify that this facility is implementing the all the provisions of the

Re: Sediment Basin/Filter System Construction
Cleveland, NC
Shamrock Proposal Number 16-GREM-18379
Dear Mr. Smith --

Shamrock Environmental Corporation (Shamrock) is pleased to provide Gem Fabrication of North
Carolina (Gem Fab) with this proposal for the above -referenced services. This proposal is based upon
information provided by Gem Fab and a recent site visit by Shamrock_
Shamrock understands that Gem Fab requires a sediment basin/filter system to remove residue/suspended
solids that may contain zinc and copper. Water sample outfall readings have exceeded regulated
parameters.
In order to meet Gem Fab's project objectives, Shamrock proposes the following services:
• Provide a two -man crew equipped with a mini -excavator and skid steer loader,
• Excavate two sediment basins. One on the east side measuring approximately 10'x6'x2' and one
on the west side measuring approximately 19'x20'x2' deep.
• Each sediment basin will have a rip rap berm with a fiber log/washed stone face to filter storm
water prior to leaving the site.
• Utilize the existing rip rap on site in the west outfall for the rip rap berms.
• Collect a water sample and send it to the manufacturer of the floc lock logs. Supply a floc lock
log specifically designed for the removal of the zinc and copper in the storm water.
• Place eleven cubic yards of wood mulch along the west side existing rip rap Swale to filter storm
water and to prevent erosion on the bare area between the building and the rip rap swale.
• Transfer excess soils from the sediment basin construction to an onsite location identified by Gem
Fab.

Gem Fabrication of North Carolina
Proposal 16-GREM-18379
May 4, 2016
Page 2 of 2
Shamrock's proposed pricing is as follows:
Mobilization
Construction of sediment basins as outlined above
Total cost
Shamrock's proposal is conditioned by the following clarifications:
$1,580.00
13 791.00
$15, 3 71. 00
• Work will be performed on consecutive weekdays, 10 hours per day.
• Gem Fab will be responsible for locating underground fire and water lines next to the west outfall
as well as any other private underground utilities in the work zone.
• Location and size of the sediment basins may be modified depending upon location of any
underground utilities.
• Gem Fab will need to monitor the sediment basins and will need to periodically clean the basins
when they become half full of silt or more often as needed.
• A water source is available near the work area.
• Mobilization is not subject to Shamrock's energy surcharge.
Thank you for considering Shamrock Environmental Corporation for the completion of this project. If
you wish to accept this proposal, you may do so by signing below, subject to the attached Terms and
Conditions, and returning a signed copy to us via email. If you have any questions or additional needs,
please contact us at [phone].

' Monthly sampling (instead of semi-annual) must begin with the second consecutive benchmark exceedance for the same parameter at the same outfall.
2 For sampling periods with no discharge at any single outfall, you must still submit this discharge monitoring report with a checkmark here.
3The 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.
S Total Toxic Organics sampling is applicable only for those facilities which perform metal finishing operations, manufacture semiconductors, manufacture
electronic crystals, or manufacture cathode ray tubes. For purposes of this permit the definition of Total 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 crystal manufacture use the definition as found in 40 CFR 469.22; and for cathode ray
tube manufacture use the definition found in 40 CFR 469.31).
Permit Date: 11/l/2012-10/31/2017 SWU-245, last revised 10/25/2012
Page 1 of 3

Facilities that incorporate a solvent management plan into the stormwater Pollution Prevention Plan may so certify, and the requirement for TTO monitoring
may tie waived. The solvent management plan shall include a list of the total toxic organic compounds used and the other elements listed in the General
Permit. For those facilities electing to employ the TTO monitoring waiver, the discharger shall sign the following certification statement:
"Based upon my inquiry of the person or persons directly responsible for managing compliance with the permit monitoring requirement for total toxic organics
(TTO), I certify that to the best of my knowledge and belief, no dumping of concentrated toxic organics into the stormwater or areas which are exposed to rainfall or
stormwater runoff has occurred since filing the last discharge monitoring report. I further certify that this facility is implementing the all the provisions of the
solvent management plan included in the Stormwater Pollution Prevention Plan."

1 Monthly sampling (instead of semi-annual) must begin with the second consecutive benchmark exceedance for the same parameter at the same outfall.
a For sampling periods with no discharge at any single outfall, you must still submit this discharge monitoring report with a checkmark here.
3The 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.
4 See General Permit, Table 3 identifying the especially sensitive receiving water classifications where the more protective benchmark applies.
5 Total Toxic Organics sampling is applicable only for those facilities which perform metal finishing operations, manufacture semiconductors, manufacture
electronic crystals, or manufacture cathode ray tubes. For purposes of this permit the definition of Total 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 crystal manufacture use the definition as found in 40 CFR 469,22; and for cathode ray
tube manufacture use the definition found in 40 CFR 469.31).
Permit Date:11/1/2012-10/31/2017 SWU-245, last revised 10/25/2012

}
facilities that incorporate a solvent management plan into the Stormwater Pollution Prevention Plan may so certify, and the requirement for TTO monitoring
may be waived. The solvent management plan shall include a list of the total toxic organic compounds used and the other elements listed in the General
Permit. For those facilities electing to employ the TTO monitoring waiver, the discharger shall sign the following certification statement:
"Based upon my Inquiry of the person or persons directly responsible for managing compliance with the permit monitoring requirement for total toxic organics
(TTO), I certify that to the best of my knowledge and belief, no dumping of concentrated toxic organics into the stormwater or areas which are exposed to rainfall or
stormwater runoff has occurred since filing the last discharge monitoring report. I further certify that this facility is implementing the all the provisions of the
solvent management plan included in the Stormwater Pollution Prevention Plan."

1 Monthly sampling (instead of semi-annual) must begin with the second consecutive benchmark exceedance for the same parameter at the same outfall.
z For sampling periods with no discharge at any single outfall, you must still submit this discharge monitoring report with a checkmark here.
3The 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.
5 Total Toxic Organics sampling is applicable only for those facilities which perform metal finishing operations, manufacture semiconductors, manufacture
electronic crystals, or manufacture cathode ray tubes. For purposes of this permit the definition of Total 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 crystal manufacture use the definition as found in 40 CFR 469.22; and for cathode ray
tube manufacture use the definition found in 40 CFR 469.31).
Permit Date: 11/1/2012-10/31/2017 SWU-245, last revised 10/25/2012
Page 1 of 3

Facilities that incorporate a solvent management plan into the Stormwater Pollution Prevention Plan may so certify, and the requirement for TTO monitoring
may be waived. The solvent management plan shall include a list of the total toxic organic compounds used and the other elements listed in the General
Permit. For.,those facilities electing to employ the TTO monitoring waiver, the discharger shall sign the following certification statement:
"Based upon my inquiry of the person or persons directly responsible for managing compliance with the permit monitoring requirement for total toxic organics
(TTO), I certify that to the best of my knowledge and belief, no dumping of concentrated toxic organics into the stormwater or areas which are exposed to rainfall or
stormwater runoff has occurred since filing the last discharge monitoring report. I further certify that this facility is implementing the all the provisions of the
solvent management plan included in the Stormwater Pollution P vention Plan."

Note: Results must be reported in numerical format. Do not report Below Detection Limit, BDL, <PQL, Non -detect, ND, or other similar non -numerical
format. When results are below the applicable limits, they, must be reported in the format, "<XX mRIL", where XX is the numerical value of the detection
limit, reporting limit, etc. in mg/L.
Note: If you report a sample value in excess of the benchmark, you must implement Tier 1, Tier 2, or Tier 3 responses. See General Permit text.
Part B: Vehicle Maintenance Area Monitoring Results: only for facilities averaging > 55 gal of new oil per month.

Re: Semi -Annual Stormwater Sampling and Analysis
Gem Fabrication, 10230 Statesville Boulevard, Cleveland, NC
Pyramid Project #2014-047
Dear Mr. Smith.
As requested by Gem Fabrication of North Carolina, Inc., Pyramid Environmental and
Engineering, PC., conducted the bi-annual stormwater sampling and analysis at the
above -referenced facility. The scope of services included, mobilization of personnel and
equipment to the site, stormwater sampling and laboratory analysis for the parameters
specified in North Carolina General Permit No. NCG030000. The Certificate of Coverage
for the current permit was issued to Gem Fabrication on December 4, 2012 and is
effective until October 31, 2017.
The subject site is located in Cleveland, North Carolina, in the western portion of Rowan
County. Figure I shows the location of the site on the Cleveland, NC USGS topographic
map. According to the USGS map, stormwater from the subject property flows into
unnamed tributaries to Withrow Creek to the east (Outfall #01) and Beaverdam Creek
(Outfall #02) to the west.
On March 3, 2013, stormwater samples were collected during a representative rain event
from Outfalls #01 and #02 and one roof drain by Brett Higgins of Pyramid. The
stormwater sample locations are shown on Figure 2. The stormwater samples were
collected in laboratory containers, placed on ice and transported to Pace Analytical
Services, Inc., in Huntersville, N.C.
The stormwater samples were analyzed for oil and grease, total suspended solids (TSS),
total recoverable copper, total recoverable lead and total recoverable zinc as required by
the new permit. The roof sample was only analyzed for total recoverable copper, lead and
zinc. The pH for each outfall was recorded in the field during sampling using a calibrated
pH meter. A summary of the laboratory results, with the benchmark concentrations listed
in General Permit NCG030000, are presented in the attached table.

www.rrvramidenvirQnmental.com

As indicated in the table, the detected concentrations of oil and grease, TSS, and total
recoverable lead in Outfalls #01 and #02 do not exceed the benchmark concentrations
specified in permit NCG030000. Also the pH levels recorded in the field for Outfalls #01
and #02 are within the benchmark range specified in NCG030000.
The detected concentration of total recoverable copper in the sample collected from
Outfall #01 exceeds the benchmark concentrations specified in NCG030000 and is
consistent with the copper concentrations detected at Outfall #01 in the past two sampling
events.
The detected concentrations of total recoverable zinc in the samples collected from
OutfalI #01 and #02 and the roof drain exceed the benchmark concentrations specified in
NCG030000. The concentration of total recoverable zinc at the roof drain indicates that
the roof of the building is most likely the source of the elevated zinc levels that have been
detected in Outfall #01 and #02 since sampling for zinc has been required as part of
permit NCG030000.
As indicated in NCG030000, exceedances of benchmark values require the permittee to
increase monitoring, increase management actions, increase record keeping and/or install
stormwater Best Management Practices (BMPs). The exceedances from the March 3,
2014 sampling event require Tier Two responses (see Part H, page 7 of NCG030000).
According to page 7, the permittee shall:
l . Repeat all the required actions outlined in Tier One (see permit).
2. Immediately institute monthly monitoring for all parameters. Conduct monthly
monitoring at every outfall where a sampling result exceeded the benchmark
value for two consecutive samples. Monthly (analytical and qualitative)
monitoring shall continue until three consecutive results are below the benchmark
value or within benchmark range.
3. Submit a monthly monitoring report indicating "No Flow" if no discharge occurs
during the sampling period.
4. Benchmark exceedances for a different parameter separately trigger a tiered
response.
5. Maintain a record of the Tier Two responses and monitoring results in the SPPP.
Please contact Pyramid if you need assistance with the implementation of the required
Tier One response actions.
The storm event characteristics and laboratory analytical results are presented on the
attached NCG030000 monitoring report. A copy of the original laboratory report and
chain of custody form is also attached for your records. Pyramid also completed
stormwater discharge outfall qualitative monitoring reports for each outfall as required in
your Stormwater Pollution Prevention Plan (SPPP). Copies of the qualitative monitoring
reports are included and should be added to the SPPP.

Pyramid Project No. 2014-047 1 03/12/14

You are required to sign pages 2 and 3 of the monitoring report, and mail the original and
one copy to the address shown on page 3 of the force. We recommend that you also
include copies of the laboratory report.
Based on the effective date of the current certificate of coverage your permit is valid until
midnight on October 31, 2017. Pyramid will attempt to conduct the next stormwater
sampling event in April 2014. If you have any questions regarding this report, please
contact us at 1-336-335-3174 at your convenience.

The laboratory results for total recoverable copper, lead and zinc are reported by
Pace Laboratories in micrograms per liter (µg/L) and were converted to mg/L in
the table above to compare to the benchmark values listed in NCG030000.
As indicated in the table, the detected concentrations of oil and grease, TSS, and total
recoverable lead in outfalls #01 and #02 do not exceed the benchmark concentrations
specified in permit NCG030000. Also the pH levels recorded in the field for outfalls #01
and #02 are within the benchmark range specified in NCG030000.

{ A
The detected concentration of total recoverable copper in the sample collected from
Outfall #01 exceeds the benchmark concentrations specified in NCG030000 and is
consistent with the copper concentrations detected at Outfall #01 in the past two sampling
events.
The detected concentrations of total recoverable zinc in the samples collected from
Outfall #01 and #02 and the roof drain exceed the benchmark concentrations specified in
NCG030000. The detected concentration of total recoverable zinc detected at the roof
drain on 3/3/14 indicates that the roof is most likely the source of,the elevated zinc levels
that have been detected in Outfall #01 and #02 since sampling for zinc has been required
as part of permit NCG030000.

Re: Semi -Annual Stormwater Sampling and Analysis
Gem Fabrication,10230 Statesville Boulevard, Cleveland, NC
Pyramid Project #2009-206
Dear Mr. Comand:
As requested by Gem Fabrication, Pyramid Environmental and Engineering, P.C.,
conducted the annual stormwater sampling and analysis for two outfalls at the above -
referenced site. The scope of services included, mobilization of personnel and equipment
to the site, stormwater sampling and laboratory analysis for the parameters specified in
North Carolina General Permit No. NCG030000.
The subject site is located in Cleveland, North Carolina, in the western portion of Rowan
County. Figure 1 shows the location of the site on the Cleveland, NC USGS topographic
reap. According to the USGS map, stormwater from the subject property flows into
unnamed tributaries to Withrow Creek and Beaverdam Creek. Figure 2 shows the
locations of the two stormwater outfalls at the facility.
On October 12, 2009, stormwater samples were collected during a representative rain
event from OutfalIs #01 and #02 by Brett Higgins of Pyramid. The stormwater samples
were collected in laboratory containers, placed on ice and transported to Prism
Laboratories, in Charlotte, N.C. The samples were analyzed for oil and grease, TSS, pH,
and total lead as required by the permit. The pH for each outfall was also recorded in the
field during sampling using a calibrated pH meter. A summary of the laboratory results,
with the benchmark concentrations listed. in General Permit NCG030000, are presented in
the attached table.
As indicated in the table, none of the laboratory results for the targeted parameters
exceeded the benchmark concentrations specified in NCG030000. The pH readings
recorded in the field did not exceed the benchmark range specified in NCG030000.

The storrn event characteristics and laboratory analytical results are presented on the
attached NCG030000 monitoring report. A copy of the original laboratory report and
chairs of custody form is also attached for your records.
Pyramid also completed stormwater discharge outfall qualitative monitoring reports for
each outfall as required in your Stormwater Pollution Prevention Plan (SPPP). Copies of
the qualitative monitoring reports are included and should be added to the SPPP.
You are required to sign the second page of the monitoring report, and mail the original
and one copy to the address shown on the first page of the form. We recommend that you
also include copies of the laboratory report.
Based on the effective date of the current certificate of coverage your permit is valid until
midr>ight on October 31, 2012. All facilities covered under general permit NCG030000
are now required to collect samples semi-annually, once between January and June and
once between July and December. Pyramid will attempt to conduct the next stormwater
sampling event between January 1, and June 29, 2010. If you have any questions
regarding this report, please contact us at 1-336-335-3174 at your convenience.

Total Toxic Organics sampling is applicable only for those facilities which perform metal finishing operations, manufacture semiconductors, manufacture electronic crystals, or
manufacture cathode ray tubes. For purposes of this permit the definition of "Total '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 crystal manufacture use the definition as found in 40 CFR 469.22; and for cathode ray tube manufacture use the definition found in 40 CFR 469.31).
Facilities that incorporate a solvent management plan into the Stormwater Pollution Prevention Plan may request that DWQ waive monitoring of total toxic organics. The solvent
management plan shall include a list of the total toxic organic compounds used and the other elements listed in the General Permit. For those facilities allowed such a waiver, the
discharger shall sign the following certification statement:
"Based upon my inquiry of the person or persons directly responsible for managing compliance with the permit monitoring requirement for total toxic organics (TTO), 1
certify that to the best of my knowledge and belief, no dumping of concentrated toxic organics into the stormwater or areas which are exposed to rainfall or stormwater
runoff has occurred since filing the last discharge monitoring report. I further certify that this facility is implementing; the all the provisions of the solvent management
plan included in the Stormwater Pollution Prevention Plan."
