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.
'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.
See General Permit, Section B, Table 1 to identify 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 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 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.
2 For sampling periods with no discharge at any single outfall, you must still submit this discharge monitoring report with a checkmark here.
3 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.
" 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
Pagel 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 Prevention Plan."

1 Monthly sampling (instead of semi-annual) must begin with the second consecutive benchmark exceedance far 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.
'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 small 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."

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

GREENSBORO, NORTH CAROLINA
TIER I PERMIT COMPLIANCE INSPECTION
As required by General Stormwater Permit No. NCG030661, a compliance evaluation
was conducted on 5I12/17 in response to stormwater analytical parameter exceedence.
Present during the inspection were:
Paul Spangenberg Consultant (Environmental Compliance Manager)
Tait Williams Plant Manager
1) Areas where industrial activities are exposed to stormwater.
a) Scrap metal storage west of main building. Scrap metal was observed to
be oil free. No obvious signs were found of an impact to stormwater from
the storage of scrap metal.
b) Used equipment. No evidence was found that an impact to stormwater has
occurred in this area.
c) Solid Waste Dumpster Area: The waste was confined to the closed top
dumpster. No evidence was seen of any impacts to stormwater in this
area.
d) Compressor Area: The area was clean with no staining. No evidence was
seen of any impacts to stormwater in this area.
e) Loading Dock Area: "the area was clean with no staining. No evidence
was seen of any impacts to stormwater in this area.
Summary: Except for some oil leakage from the yard crane, the following
were not found during the inspection:
a) leaks or spills from equipment, drums, barrels, or containers
b) off site tracking of industrial materials
c) tracking or blowing of raw, final, or waste materials
d) evidence or, or the potential for, pollutants entering the drainage system.
2) Analytical monitoring results from sampling conducted on September 25, 2015
indicated the following exceedance.

No sources were found to elevate the zinc to exceed the range was found during
the inspection.
3) There are no structural BMP's present at the facility. No retention ponds or
collection basins are present. The facility captures compressor condensate and
discharges it back to the city. None structural BMP's include the minimization of
outdoor storage, the frequent disposal of accumulated wastes, and the elimination
of any oily wastes. These non-structural BMP's appear to be adequate.
4) The stormwater discharge outfall was inspected. No evidence was seen of any
non-stormwater impacts at the outfall.
RECOMMENDATIONS
l) Continue to BPM's in accordance with the permit.
2) Remove the stormwater exposed galvanized scrap metal stored outside the
building near the loading dock.
3) No evidence was found that the current SWPPP has any deficiencies. No changes
to the SWPPP are recommended now. All current initiatives appear adequate to
meet the goals of the SWPPP. Note that the SWPPP was implemented on -
4/21 /2017, prior to the date that the inspection was conducted.
CERTIFICATION
This inspection did not reveal any violations of the permit. No areas of non-compliance
with the SWPPP were noted.

1) Areas where industrial activities are exposed to stormwater. CENTRAL FILES
DWR SECTION
a) Scrap metal storage areas. Scrap metal was observed to be oil free. No
obvious signs were found of an impact to stormwater from the storage of
scrap metal.
b) Used equipment storage areas. No evidence was found that an impact to
stormwater has occurred in this area.
c) Solid Waste Dumpster Areas: No evidence was seen of any impacts to
stormwater in this area.
d) Compressor Areas: Some minor staining was present. A separator is being
implemented for the condensation.
e) Loading Dock Areas: The area was clean with no staining. No evidence
was seen ol'any impacts to stormwater in this area.
f) There was erosion occurring in and around the outfall and at several point
in the stormwater drainage systems throughout the property.
Summary: With the exception of some oil leakage from the yard crane, the
following were not found during the inspection:
a) leaks or spills from equipment, drums, barrels, or containers
b) off site tracking of industrial materials
c) tracking or blowing of raw, final, or waste materials
d) evidence or, or the potential for, pollutants entering the drainage system.

It has been determined that the rain fall was acidic causing the elevated level
copper and the lower level of pH. "There was no possible source copper. it is
suspected of a possible cross contamination during sampling procedures. There
was erosion occurring at the outfall discharge point and in the stormwater
drainage systems throughout the property.
3) 'There are no structural BMP's present at the facility. No retention ponds or
collection basins are present. The facility captures compressor condensate and
discharges it back to the city. None structural BMP's include the minimization of
outdoor storage, the frequent disposal of accumulated wastes, and the elimination
of any oily wastes. These non-structural BMP's appear to be adequate.
4) The stormwater discharge outfall was inspected. No evidence was seen of any
non-stormwater impacts at the outfall.
RE -COMMENDATIONS
1) Continue to BPM's in accordance with the permit.
2) Implement erosion control measures (Rip Rap) in the areas of the outfall
discharge and the stormwater drainage systems where needed throughout the
property.
3) No evidence was found that the current SWPPP has any deficiencies. No changes
to the SWPPP are recommended at this time. All current initiatives appear
adequate to meet the goals of the SWPPP. Note that the SWPPP was
implemented on 4/19/2017, prior to the date that the inspection was conducted.
ChRTIFICATION
This inspection did not reveal any violations of the permit. No areas of non-compliance
with the SWPPP were noted.

1 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 mere.
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."

z For sampling periods with no discharge at any single outfall, you must still submit this discharge monitoring report with a checkroark 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.
° 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 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. Fo,%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 durnping 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."

TIER II PERMIT COMPLIANCE INSPECTION
RECOVED
AUG 15 Z016
CENTRAL FILES
DIVR SECTION
As required by General Stonnwater Permit No. NCG030661, a compliance evaluation
was conducted on 6/29/16 in response to stormwater analytical parameter exceedence.
Present during the inspection were:
Paul Spangenberg Consultant (Environmental Compliance Manager)
Press Brower VP of Engineering
Tait Williams Plant Manager
1) Areas where industrial activities are exposed to stormwater.
a) Scrap metal storage west of main building. Scrap metal was observed to
be oil free. No obvious signs were found of an impact to stormwater from
the storage of scrap metal.
b) Used equipment. No evidence was found that an impact to stormwater has
occurred in this area.
c) Solid Waste Dumpster Area: No evidence was seen of any impacts to
stormwater in this area.
d) Compressor Area: Some minor staining was present due to a
malfunctioning separator. The area was being clean.
e) Loading Dock Area: The area was clean with no staining. No evidence
was seen of any impacts to stormwater in this area.
Summary: With the exception of some oil leakage from the yard crane, the
following were not found during the inspection:
a) leaks or spills from equipment, drums, barrels, or containers
b) off site tracking of industrial materials
c) tracking or blowing of raw, final, or waste materials
d) evidence or, or the potential for, pollutants entering the drainage system.
2) Analytical monitoring results from sampling conducted on June 15, 2016
indicated the following; exceedance.

It has been determined that the rain fall was acidic causing the elevated level zinc.
A possible source may be runoff from the corrugated galvanized steel
manufacturing building, galvanized scrap metal stored outside, or the
decomposing galvanized fencing. No other sources were found to elevate the zinc
to exceed the range was found during the inspection.
3) There are no structural BMP's present at the facility. No retention ponds or
collection basins are present. The facility captures compressor condensate and
discharges it back to the city. None structural BMP's include the minimization of
outdoor storage, the frequent disposal of accumulated wastes, and the elimination
of any oily wastes. These non-structural BMP's appear to be adequate.
4) The stormwater discharge outfall was inspected. No evidence was seen of any
non-stormwater impacts at the outfall.
RECOMMENDATIONS
1) Continue to BPM's in accordance with the permit.
2) Remove the stormwater exposed galvanized scrap metal stored outside the
building near the loading dock.
3) No evidence was found that the current SWPPP has any deficiencies. No changes
to the SWPPP are recommended at this time. All current initiatives appear
adequate to meet the goals of the SWPPP. Note that the SWPPP was updated on -
4/15/2016, prior to the date that the inspection was conducted.
CERTIFICATION
This inspection did not reveal any violations of the permit. No areas of non-compliance
with the SWPPP were noted.

' 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).

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."
