Stormwater Discharge Outfall Monitoring Reports
Matcor Metal Fabrication- Year 2- Period I- January-June-2019
Welcome. North Carolina
Waters Edge Job No R l 1-47
Dear Mr. Edwards:
Waters Edge Environmental, LLC (Waters Edge) is pleased to provide two copies of the Year 2-
Period I- January -June 2019 forms for the semi-annual site inspections at the Matcor Metal
Fabrication facility located in Welcome, North Carolina (see Figures I and 2). The past permit
has expired in October 2017; however, it is our understanding that Matcor does not have to
petition to renew since they are under a General Permit NCGO300000 (Part III -Section B- Subpart
#1) and want merely to continue under the existing permit. We have completed the Discharge
Outfall Qualitative Monitoring Report. Waters Edge also performed the stormwater sampling and
have filled out the Stormwater Discharge Outfall Monitoring Report (both report included in
Appendix A)_ Laboratory analytical results are documented in Appendix B. Based on these
results, we have exceedances for the following:
+ Outfall001
1. Exceedance for copper which was detected at 0.0158 ntg/L versus a benchmark at
0.007 mg/L.
2. Exceedance for zinc which was detected at 0.474 mg/L versus a benchmark at
0.067 mgfL.
• Outfall 002
I. Exceedance for copper which was detected at 0.0228 mg/L versus a benchmark at
0.007 mg/L.
2. Exceedance for zinc which was detected at 0,752 mg/L versus a benchmark at
0.067 mg/L.
Based on the permit conditions, we will conduct a Tier 1 inspection of the facility. Any action
items which will be reviewed and potential deficiencies addressed. The Tier 1 response will be
recorded in the Stormwater Pollution Prevention Plan.
Again, as detailed in earlier reports, due to the lowered benchmark thresholds resulting in
benchmark exceedances. we previously sampled an upgradient surface water stream on the site
(upgradient Lake Drive) as well as two samples collected from the roof drains. Both roof drain

samples exceeded the zinc benchmark level at 0.067 mg/L (Roof- l at 1.9 mg/L, and Roof-2 at
0.23 mg/L). The background upgradient surface water samples were below the zinc benchmarks.
Based on these results, we would conclude the following:
Metals are present in the upgradient surface water sample at the facility. Even though they
are below the zinc benchmarks. this metal is still present and can potentially be a
constituting factor to the outfall values detected.
Copper and zinc contained in the building materials or downspouts are also contributing to
the zinc in the stormwater which would have nothing to do with the industrial activity at
the site.
While use understand that multiple exceedances from the same Outfall require a Tier II response,
we believe that the other contributing factors to the exceedances are mitigating factors; therefore,
we will continue with our normal sampling frequency. While we will continue to attempt to
improve the stormwater quality at the facility, we believe that these type of metals exceedances
are largely due to non -industrial sources and can be found in a wide variety of non -industrial
settings (e.g. residential or any structures with metal components).
If there are any questions, please contact us at Arahn(?watersed_ eenv_com.

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 fount in 40 CFR 469A2; 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 so certify, and the requirement for TTO monitoring
may be waived. The solvent management plan shall indude 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.'

Welcome, North Carolina RECEAVE®
Waters Edge Job No R 1 1-47
Dear Mr. Edwards: CEINITRAL FILES
DWR SECTION
Waters Edge Environmental. LLC (Waters Edge) is pleased to provide two copies of the Year 1-
Period 2- July-Decembcr 2018 forms for the semi-annual site inspections at the Matcor Metal
Fabrication facility located in Welcome, North Carolina (see Figures 1 and 2). The past permit
has expired in October 2017, however, it is our understanding that Matcor does not have to
petition to renew since they are under a General Permit NCG0300000 (Part II[ -Section B- Subpart
4 1) and want merely to continue under the existing permit. We have completed the Discharge
Outfall Qualitative Monitoring Report. Waters Edge also performed the stormwater sampling and
have filled out the Stormwater Discharge Outfall Monitoring Report (both report included in
Appendix A). Laboratory analytical results are documented in Appendix B. Based on these
results, we have exceedances for the following:
• Outfall001
. Exceedance for copper which was detected at 0.0286 mg/L versus a benchmark at
0.007 mg/L.
2. Exceedance for zinc which was detected at 0.442 mg/L versus a benchmark at
0.067 mg/L.
• Outfall002
1. Exceedance for copper which was detected at 0.0076 mg/L versus a benchmark at
0.007 mg/L.
2. Exceedance for zinc which was detected at 0,250 mg/L versus a benchmark at
0.067 mg/L.
Based on the permit conditions, we will conduct a Tier I inspection of the facility. Any action
items which will be reviewed and potential deficiencies addressed. The Tier I response will be
recorded in the Stormwater Pollution Prevention Plan.
Again, as detailed in earlier reports, due to the lowered benchmark thresholds resulting in
benchmark exceedances, we previously sampled an upgradient surface water stream on the site
(upgradient Lake Drive) as well as two samples collected from the roof drains. Both roof drain

samples exceeded the zinc benchmark level at 0.067 mg/L (Roof I at 1.9 mg/L. and Roof-2 at
0.23 mglL). The background upgradient surface water samples were below the zinc benchmarks.
Based on these results, we would conclude the following:
• Metals arc present in the upgradient surface water sample at the facility. Even though they
are below the zinc benchmarks, this metal is still present and can potentially be a
constitutim, factor to the outfall values detected.
• Copper and zinc contained in the building materials or downspouts are also contributing to
the zinc in the stormwater which would have nothing to do with the industrial activity at
the site.
While we will continue to attempt to improve the stormwater quality at the facility, we believe
that these type of metals exceedances are largely due to non -industrial sources and can be found
in a wide variety of non -industrial settings (e.g. residential or any structures with metal
components).
If there are any questions, please contact us at prahnOwwatersedgeenv.com.

Reference: Stormwater Discharge Outfall Qualitative Monitoring Report and
Stormwater Discharge Outfall Monitoring Reports
Matcor Metal Fabrication- Year 5- Period 2- July -December 2017
Welcome, North Carolina
Waters Edge Job No R11-47
Dear Mr. Edwards:
Waters Edge Environmental, LLC (Waters Edge) is pleased to provide two copies of the Year 5-
Period 2- July -December 2017 forms for the semi-annual site inspections at the Matcor Metal
Fabrication facility located in Welcome. North Carolina (see Figures 1 and 2). We have
completed the Discharge Outfall Qualitative Monitoring Report. Waters Edge also performed the
stormwater sampling and have filled out the Stormwater Discharge Outfall Monitoring Report
(both report included in Appendix A). Laboratory analytical results are documented in Appendix
B. Based on these results, we have exceedances for the following:
Outfall 001
1. Exceedance for zinc which was detected at 0.734 mull, versus a benchmark at
0.067 mg/L.
Outfa11002
1. Exceedance for zinc which was detected at 0.943 mg/L versus a benchmark at
0.067 mg/L.
Based on the permit conditions, we will conduct a Tier 1 inspection of the facility. Any action
items which will be reviewed and potential deficiencies addressed. The Tier 1 response will be
recorded in the Stormwater Pollution Prevention Plan.
Again, as detailed in earlier reports, due to the lowered benchmark thresholds resulting in
benchmark exceedances, we previously sampled an upgradient surface water stream on the site
(upgradient Lake Drive) as well as two samples collected from the roof drains. Both roof drain
samples exceeded the zinc benchmark level at 0.067 mg/L (Roof-1 at 1.9 mg/L, and Roof-2 at
0.23 mg/L). The background upgradient surface water samples were below the zinc benchmarks.
Based on these results, we would conclude the following:
Metals are present in the upgradient surface water sample at the facility. Even though they
are below the zinc benchmarks, this metal is still present and can potentially be a

• Zinc contained in the building materials or downspouts are also contributing to the zinc in
the stormwater which would have nothing to do with the industrial activity at the site.
While we will continue to attempt to improve the Stormwater quality at the facility, we believe
that these type of metals exceedances are largely due to non -industrial sources and can be found
in a wide variety of non -industrial settings (e.g. residential or any structures with metal
components).
Waters Edge appreciates this opportunity to work with Matcor Metal Fabrication. If you have
any questions or require any additional information, please contact me at 919.8599987 or at

x 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.
'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 forthe 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 so certify, and the requirement for I TO 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."

Stormwater Discharge Outfall Monitoring Reports
Matcor Metal Fabrication- Year 5- Period I - January -June 2017
Welcome, North Carolina
Waters Edge Job No R 1 l -47 n1 C U 0 3 O to /_3
Dear Mr. Edwards:
Waters Edge Environmental, LLC (Waters Edge) is pleased to provide two copies of the Year 5-
Period 1- January -June 2017 forms for the semi-annual site inspections at the Matcor Metal
Fabrication facility located in Welcome, North Carolina (see Figures 1 and 2). We have
completed the Discharge Outfall Qualitative Monitoring Report. Waters Edge also performed the
stormwater sampling and have filled out the Stormwater Discharge Outfall Monitoring Report
(both report included in Appendix A). Laboratory analytical results are documented in Appendix
B. Based on these results, we have exceedances for the following:
• Outfal1001
1. Exceedance for copper which was detected at 0.0 12 1 mg/L versus a benchmark at
0.007 mg/L.
2. Exceedance for zinc which was detected at 0.659 mg/L versus a benchmark at
0.067 mg/L.
• Outfall002
1. Exceedance for zinc which was detected at 0.819 mg/L versus a benchmark at
0.067 mg/L.
Based on the permit conditions, we will conduct a Tier 1 inspection of the facility. Any action
items which will be reviewed and potential deficiencies addressed. The Tier 1 response will be
recorded in the Stormwater Pollution Prevention Plan.
Again, as detailed in earlier reports, due to the lowered benchmark thresholds resulting in
benchmark exceedances; we previously sampled an upgradient surface water stream on the site
(upgradient Lake Drive) as well as two samples collected from the roof drains. While there were
no exceedances for copper, both roof drain samples exceeded the zinc benchmark level at 0.067
mg/L (Roof- I at 1.9 mg/L, and Roof-2 at 0.23 mg/L). The background upgradient surface water
samples were below both the copper and zinc benchmarks. Based on these results, we would
conclude the following:

Stormwater Discharge Monitoring Report and Tier 1 Response
Year 5- Period 1- January -June 2017
Matcor Metal Fabrication
Welcome, NC
Page 2 of 2
April21, 2017
• Metals are present in the upgradient surface water sample at the facility. Even though they
are below the copper and zinc benchmarks, these metals are still present and can
potentially be a constituting factor to the outfall values detected.
• Zinc contained in the building materials or downspouts are also contributing to the zinc in
the stormwater which would have nothing to do with the industrial activity at the site.
While we will continue to attempt to improve the stormwater quality at the facility, we believe
that these type of metals exceedances are largely due to non -industrial sources and can be found
in a wide variety of non -industrial settings (e.g. residential or any structures with metal
components).
Waters Edge appreciates this opportunity to work with Matcor Metal Fabrication. If you have
any questions or require any additional information, please contact me at 919.859.9987 or at

' 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).

Facilities that incorporate a solvent management plan into the 5tormwater 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 TTQ 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
(70), 1 certify that to the best of my knowledge and belief, no clumping of concentrated toxic organics into the stormwater or'areas which are exposed to rainfall or
5tormwater 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 5tormwater Pollution Prevention Plan."

x 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).

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 arganic compounds used and the other elements listed in the General
Permit. For those facilities electing to employ the T O 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
(70), 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 5tormwrater Pollution Prevention Plan."

Matcor Metal Fabrication- Year 4- Period 2- July -December 2016
Welcome, North Carolina
Waters Edge Job No R11-47
Dear Mr. Edwards:
Waters Edge Environmental, LLC (Waters Edge) is pleased to provide two copies of the Year 4-
Period 2 (July -December 2015) 2015 forms for the semi-annual site inspections at the Matcor
Metal Fabrication facility located in Welcome, North Carolina (see Figures 1 and 2). We have
completed the Discharge Outfali Qualitative Monitoring Report. Waters Edge also performed the
stormwater sampling and have filled out the Stormwater Discharge Outfall Monitoring Report
(both report included in Appendix A). Laboratory analytical results are documented in Appendix
B. Based on these results, we have exceedances for the following:
Outfall 001
1. Exceedance for copper which was detected at 0.0472 mg/L versus a benchmark at
0.007 mg/L.
2. Exceedance for zinc which was detected at 0.622 mg/L versus a benchmark at
0.067 mg/L.
Outfall 002
1. Exceedance for copper which was detected at 0.0104 mg/L versus a benchmark at
0.007 mg/L.
2. Exceedance for zinc which was detected at 0.545 mg/L versus a benchmark at
0.067 mg/L.
Based on the permit conditions, we will conduct a Tier 1 inspection of the facility. Any action
items which will be reviewed and potential deficiencies addressed. The Tier 1. response will be
recorded in the Stormwater Pollution Prevention Plan.
Again, as detailed in earlier reports, due to the lowered benchmark thresholds resulting in
benchmark exceedances, we previously sampled an upgradient surface water stream on the site
(upgradient Lake Drive) as well as two samples collected from the roof drains. While there were
no exceedances for copper, both roof drain samples exceeded the zinc benchmark level at 0.067
mg/L (Roof-1 at 1.9 mg/L, and Roof-2 at 0.23 mg/L). The background upgradient surface water

samples were below both the copper and zinc benchmarks. Based on these results, we would
conclude the following:
• Metals are present in the upgradient surface water sample at the facility. Even though they
are below the copper and zinc benchmarks; these metals are still present and can
potentially be a constituting factor to the outfall values detected.
• Zinc contained in the building materials or downspouts are also contributing to the zinc in
the stormwater which would have nothing to do with the industrial activity at the site.
While we will continue to attempt to improve the stormwater quality at the facility, we believe
that these type of metals exceedances are largely due to non -industrial sources and can be found
in a wide variety of non -industrial settings (e.g. residential or any structures with metal
components). Nonetheless, we do understand that this exceedance will result in a Tier 2 response
requiring monthly sampling for both Outfalls.
Waters Edge appreciates this opportunity to work with Matcor Metal Fabrication. If you have
any questions or require any additional information, please contact me at 919.859.9987 or at

Mr. Joe Edwards, EHS Officer
Matcor Metal Fabrication
835 Salem Road
Welcome, North Carolina 27374
Reference: Stormwater Discharge Outfall Qualitative Monitoring Report and
Stormwater Discharge Outfall Monitoring Reports
Matcor Metal Fabrication- Year 3- Period 2- July -December 2015
Welcome, North Carolina
Waters Edge Job No R11-47
Dear Mr. Edwards:
Waters Edge Environmental, LLC (Waters Edge) is pleased to provide two copies of the Year 3-
Period 2 (July -December 2015) 2015 forms for the semi-annual site inspections at the Matcor
Metal Fabrication facility located in Welcome, North Carolina (see Figures I and 2). We have
completed the Discharge Outfall Qualitative Monitoring Report. Waters Edge also performed the
stormwater sampling and have filled out the Stormwater Discharge Outfall Monitoring Report
(both report included in Appendix A). Laboratory analytical results are documented in Appendix
B. Based on these results, we have exceedances for the following:
0 Outfall00i
1. Exceedance for copper which was detected at 0.0084 mg/L versus a benchmark at
0.007 mg/L.
2. Exceedance for zinc which was detected at 0.171 mg/L versus a benchmark at
0.067 mg/L.
Outfal1 002
1. Exceedance for zinc which was detected at 0.507 mg/L versus a benchmark at
0.067 mg/L.
Based on the permit conditions, we will conduct a Tier 1 inspection of the facility. Any action
items which will be reviewed and potential deficiencies addressed. The Tier 1 response will be
recorded in the Stormwater Pollution Prevention Plan.
Again, as detailed in earlier reports, due to the lowered benchmark thresholds resulting in
benchmark exceedances, we previously sampled an upgradient surface water stream on the site
(upgradient Lake Drive) as well as two samples collected from the roof drains. While there were
no exceedances for copper, both roof drain samples exceeded the zinc benchmark level at 0.067
mg/L (Roof-1 at 1.9 mg/L, and Roof-2 at 0.23 mg/L). The background upgradient surface water
samples were below both the copper and zinc benchmarks. Based on these results, we would
conclude the following:

Stormwater Discharge Monitoring Report and Tier I Response
Year 3- Period 2- July -December 2015
Matcor Metal Fabrication
Welcome, NC
Page 2 of 2
December 23, 2015
• Metals are present in the upgradient surface water sample at the facility. Even though they
are below the copper and zinc benchmarks, these metals are still present and can
potentially be a constituting factor to the outfall values detected.
• Zinc contained in the building materials or downspouts are also contributing to the zinc in
the stormwater which would have nothing to do with the industrial activity at the site.
While we will continue to attempt to improve the stormwater quality at the facility, we believe
that these type of metals exceedances are largely due to non -industrial sources and can be found
in a wide variety of non -industrial settings (e.g. residential or any structures with metal
components). Nonetheless, we do understand that this exceedance will result in a Tier 2 response
requiring monthly sampling for both Outfalls.
Waters Edge appreciates this opportunity to work with Matcor Metal Fabrication. If you have
any questions or require any additional information, please contact me at 919.859.9987 or at
[e-mail].

1 Monthly sampling (instead of serni-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

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. 1 further certify that this facility is implementing the all the provisions of the
solvent management plan included in the Stormwater Pollution Prevention Plan."

Welcome, North Carolina
Waters Edge Job No R 1 1-47
Dear Mr. Edwards:
Waters Edge Environmental, LLC (Waters Edge) is pleased to provide two copies of the Year32-
Period I (January -June 2015) 2014 forms for the semi-annual site inspections at the Matcor Metal
Fabrication facility located in Welcome, North Carolina (see Figures 1 and 2). We have
completed the Discharge Outfall Qualitative Monitoring Report. Waters Edge also performed the
stormwater sampling and have filled out the Stormwater Discharge Outfall Monitoring Report
(both report included in Appendix A). Laboratory analytical results are documented in Appendix
B. Due to a sampling error, we did have to do the TPH samples on a second event on June 19,
2015 but it was still within the sampling period. Based on these results, we have exceedances for
the following:
• Outfall001
1. Exceedance for copper which was detected at 0.0122 mg/L versus a benchmark at
0.007 mg/L.
2. Exceedance for zinc which was detected at 0.709 mg/L versus a benchmark at
0.067 mg/L.
• Outfall 002
1. Exceedance for zinc which was detected at 0.307 mg/L versus a benchmark at
0.067 mg/L.
Based on the permit conditions. we will conduct a Tier 1 inspection of the facility. Any action
items which will be reviewed and potential deficiencies addressed. The Tier I response will be
recorded in the Stormwater Pollution Prevention Plan.
Again, as detailed in earlier reports, due to the lowered benchmark thresholds resulting in
benchmark exceedances, we previously sampled an upgradient surface water stream on the site
(upgradicnt lake drive) as well as two samples collected from the roof drains. While there were
no exceedances for copper, both roof drain samples exceeded the zinc benchmark level at 0.067
mg/L (Roof-1 at 1.9 mg/L.. and Roof-2 at 0.23 mg/L). The background upgradient surface water

samples were below both the copper and zinc benchmarks. Based on these results, we would
conclude the following:
• Metals are present in the upgradient surface water sample at the facility. Even though they
are below the copper and zinc benchmarks, these metals are still present and can
potentially be a constituting factor to the outfall values detected.
• Zinc contained in the building materials or downspouts are also contributing to the zinc in
the stormwater which would have nothing to do with the industrial activity at the site.
While we will continue to attempt to improve the Stormwater quality at the facility, we believe
that these type of metals exceedances are largely due to non -industrial sources and can be found
in a wide variety of non -industrial settings (e.g. residential or any structures with metal
components). Nonetheless, we do understand that this exceedance will result in a Tier 2 response
requiring monthly sampling for both Outfalls.

any questions or require any additional information, please contact me at 919.859.9987 or at

' 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 tunes. 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 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), 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 fling the last discharge monitoring report. 1 further certify that this facility is implementing the all the provisions of the

Reference: Stormwater Discharge Outfall Qualitative Monitoring Report and
Stormwater Discharge Outfall Monitoring Reports
Matcor Metal Fabrication- Year 2- Period 1- Jan -June 2014
Welcome. North Carolina
Waters Edge Job No Rl 1-47
Dear Mr. Edwards:
Waters Edge Environmental, LLC (Waters Edge) is pleased to provide two copies of the Year 2-
Period 1 (Jan- June 2014) 2014 forms for the semi-annual site inspections at the Matcor Metal
Fabrication facility located in Welcome, North Carolina (see Figures 1 and 2). We have
completed the Discharge Outfall Qualitative Monitoring Report. Waters Edge also performed the
stormwater sampling and have filled out the Stormwater Discharge Outfall Monitoring Report
(both report included in Appendix A). Laboratory analytical results are documented in Appendix
B. Based on these results, we have exceedances for the following:
• Outfall001
i . Exceedance for total suspended solids (TSS) which was detected at 167 mg/L
versus a benchmark at 100 mg/L.
2. Exceedance for copper which was detected at 0.0104 mg/L versus a benchmark at
0.007 mg/L.
3. Exceedance for zinc which was detected at 0.212 mg/L versus a benchmark at
0.067 mg/L.
• Outfall002
1. Exceedance for total suspended solids (TSS) which was detected at 181 mg/L
versus a benchmark at 100 mg/L.
2. Exceedance for copper which was detected at 0.0115 mg/L versus a benchmark at
0.007 mg/L.
3. Exceedance for zinc which was detected at 0.233 mg/L versus a benchmark at
0.067 mg/L.
Based on the permit conditions, we will conduct a Tier 1 inspection of the facility. Any action
items which will be reviewed and potential deficiencies addressed. The Tier 1 response will be
recorded in the Stormwater Pollution Prevention Plan.
Due to the lowered benchmark thresholds resulting in benchmark exceedances, we previously
sampled an upgradient surface water stream on the site (upgradient lake drive) as well as two

Welcome, _'VC

samples collected from the roof drains. While there were no exceedances for copper, both roof
drain samples exceeded the zinc benchmark level at 0.067 mg/L (Roof-1 at 1.9 mg/L, and Roof-2
at 0.23 mg/L). The background upgradient surface water samples were below both the copper
and zinc benchmarks. Based on these results, we would conclude the following:
* Metals are present in the upgradient surface water sample at the facility. Even though they
are below the copper and zinc benchmarks, these metals are still present and can
potentially be a constituting factor to the outfall values detected.
• Zinc contained in the building; materials or downspouts are also contributing to the zinc in
the stormwater which would have nothing to do with the industrial activity at the site.
While we will continue to attempt to improve the stormwater quality at the facility, we believe
that these type of metals exceedances are largely due to non -industrial sources and can be found
in a wide variety of non -industrial settings (e.g. residential or any structures with metal
components). Nonetheless; we do understand that this exceedance will result in a Tier 2 response
requiring monthly sampling for both Outfalls.
Waters Edge appreciates this opportunity to work with Matcor Metal Fabrication. If you have
any questions or require any additional information, please contact me at 919.859.9987 or at

' 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.
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 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 Stormwater Pollution Prevention Plan."

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 maybe 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 forthe 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).

_ Dear Mr. Edwards:
Waters Edge Environmental, LLC (Waters Edge) is pleased to provide two copies of the Fall 2011 forms for
the semi-annual site inspections at the Matcor Metal Fabrication facility located in Welcome, North Carolina.
We have completed the Discharge Outfall Qualitative Monitoring Report. Waters Edge also performed the
stormwater sampling and have filled out the Stormwater Discharge Outfall Monitoring Report (both report
included in Appendix A). Laboratory analytical results are documented in Appendix B. Based on the TSS
exceedances above the benchmark value in your permit, you are required to submit a stormwater management
inspection within two weeks to identify potential causes of the exceedances and then implement corrections
within two months which is all recorded on your Stormwater PPP.
Waters Edge appreciates this opportunity to work with Matcor Metal Fabrication. If you have any questions or
