FLAGS/NOTES AND DEFINITIONS
a The analyte was detected in the associated method blank.
D The sample was analyzed at dilution.
J The reported value is between the laboratory method detection limit (MDL) and the laboratory method
reporting limit (MRL), adjusted for actual sample preparation data and moisture content, where applicable.
U The analyte was analyzed for but not detected to the level shown, adjusted for actual sample preparation
data and moisture content, where applicable.
E The concentration indicated for this analyte is an estimated value above the calibration range of the
instrument. This value is considered an estimate.
MRL Method Reporting Limit. The MRL is roughly equivalent to the practical cluantitation limit (PQL) and is
based on the low point of the calibration curve, when applicable, sample preparation factor, dilution
factor, and, in the case of soil samples, moisture content.
PQL PQL. Practical Quantitation limit. The PQL presented is the laboratory MRL.
N The analysis indicates the presence of an analyte for which there is presumptive evidence (85% or greater
confidence) to make a "tentative identification".
P Greater than 25% concentration difference was observed between the primary and secondary GC column.
The lower concentration is reported.
[CALC] Calculated analyte - MDLJMRL reported to the highest reporting limit of the component analyses.
1-06 The associated laboratory control sample exhibited low bias; the reported result should be considered to
be a minimum estimate.
0-05 This sample was extracted outside of the EPA recommended holding time.
QM-07 The spike recovery was outside acceptance limits for the MS and/or MSD. The batch was accepted based
on acceptable LCS recovery.
QM-ii Precision between duplicate matrix spikes of the same sample was outside acceptance limits.
QS-03 Surrogate recovery outside acceptance limits
QV-01 The associated continuing calibration verification standard exhibited high bias; since the result is ND, there
is no impact.
QV-02 The associated continuing calibration verification standard exhibited low bias; the reported result should
be considered to be a minimum estimate.

Qualitative monitoring requirements vary. Most permits require qualitative monitoring to be
performed during a "representative storm event' or during a "measureable storm event" However,
some permits do not have this requirement. Please refer to these definitions, if applicable.
A "representative storm event" is a storm event that measures greater than 0.1 inches of rainfall
and that is preceded by at least 72 hours (3 days) in which no storm event measuring greater than
0.1 inches has occurred. A single storm event may contain up to 10 consecutive hours of no
precipitation.
A "measurable storm event" is a storm event that results in an actual discharge from the
permitted site outfall. The previous measurable storm event must have been at least 72 hours
prior. The 72-hour storm interval does not apply if the permittee is able to document that a shorter
interval is representative for local storm events during the sampling period, and the permittee
obtains approval from the local DWQ Regional Office.

FLAGS/NOTES AND DEFINITIONS
B The analyte was detected in the associated method blank.
D The sample was analyzed at dilution.
] The reported value is between the laboratory method detection limit (MDL) and the laboratory method
reporting limit (MRL), adjusted for actual sample preparation data and moisture content, where applicable.
U The analyte was analyzed for but not detected to the level shown, adjusted for actual sample preparation
data and moisture content, where applicable.
E The concentration indicated for this analyte is an estimated value above the calibration range of the
instrument. This value is considered an estimate.
MRL Method Reporting Limit. The MRL is roughly equivalent to the practical quantitadon limit (PQL) and is
based on the low point of the calibration curve, when applicable, sample preparation factor, dilution
factor, and, in the case of soil samples, moisture content.
PQL PQL: Practical Quantitation Limit. The PQL presented is the laboratory MRL.
N The analysis indicates the presence of an analyte for which there is presumptive evidence (850/c, or greater
confidence) to make a "tentative identification".
P Greater than 25% concentration difference was observed between the primary and secondary GC column.
The lower concentration is reported.
3-04 Result may be biased high. Associated calibration verification standard exceeded the upper
control limit.
3-06 The associated laboratory control sample exhibited low bias; the reported result should be
considered to be a minimum estimate.
QM-07 The spike recovery was outside acceptance limits for the MS and/or MSD. The batch was
accepted based on acceptable LC5 recovery.
QV-01 The associated continuing calibration verification standard exhibited high bias; since the result is
ND, there is no impact.
QV-02 The associated continuing calibration verification standard exhibited low bias; the reported
result should be considered to be a minimum estimate.

Please verify whether Qualitative Monitoring must be performed during a "representative storm
event" or "measureable storm event" (requirements vary, depending on the permit).
Qualitative monitoring requirements vary. Most permits require qualitative monitoring to be
performed during a "representative storm event" or during a "measureable storm event." However,
some permits do not have this requirement. Please refer to these definitions, if applicable.
A "representative storm event" is a storm event that measures greater than 0.1 inches of rainfall
and that is preceded by at least 72 hours (3 days) in which no storm event measuring greater than
0.1 inches has occurred. A single storm event may contain up to 10 consecutive hours of no
precipitation.
A "measurable storm event" is a storm event that results in an actual discharge from the
permitted site outfall. The previous measurable storm event must have been at least 72 hours
prior. The 72-hour storm interval does not apply if the permittee is able to document that a shorter
interval is representative for local storm events during the sampling period, and the permittee
obtains approval from the local DWQ Regional Office.

Please verify whether Qualitative Monitoring must be performed during a "representative storm
event" or "measureable storm event" (requirements vary, depending on the permit).
Qualitative monitoring requirements vary. Most permits require qualitative monitoring to be
performed during a "representative storm event" or during a "measureable storm event" However,
some permits do not have this requirement. Please refer to these definitions, if applicable.
A "representative storm event" is a storm event that measures�greater than 0.1 inches of rainfall
and that is preceded by at least 72 hours (3 days) in which no storm event measuring greater than
0.1 inches has occurred. A single storm event may contain up to 10 consecutive hours of no
precipitation.
A "measurable storm event" is a storm event that results in an actual discharge from the
permitted site outfall. The previous measurable storm event must have been at least 72 hours
prior, The 72-hour storm interval does not apply if the permittee is able to document that a shorter
interval is representative for local storm events during the sampling period, and the permittee
obtains approval from the local DWQ Regional Office.
By thiVignature, I certi hat this report is accurate and complete to the best of my knowledge:

FLAGS/NOTES AND DEFINITIONS
B The analyte was detected in the associated method blank.
D The sample was analyzed at dilution.
] The reported value is between the laboratory method detection limit (MDQ and the laboratory method
reporting limit (MRL), adjusted for actual sample preparation data and moisture content, where applicable.
U The analyte was analyzed for but not detected to the level shown, adjusted for actual sample preparation
data and moisture content, where applicable.
E The concentration indicated for this analyte is an estimated value above the calibration range of the
instrument. This value is considered an estimate.
MRL Method Reporting Limit. The MRL is roughly equivalent to the practical quantitation limit (PQL) and is
based on the low point of the calibration curve, when applicable, sample preparation factor, dilution
factor, and, in the case of soil samples, moisture content.
PQL PQL: Practical Quantitation Limit.
N The analysis indicates the presence of an analyte for which there is presumptive evidence (85% or greater
confidence) to make a "tentative identification".
P Greater than 25% concentration difference was observed between the primary and secondary GC column.
The lower concentration is reported.

R' Yes ❑ No
Please verify whether Quolitative Monitoring must be performed during a "representative storm
event" or "measureable storm event" (requirements vary, depending on the permit).
Qualitative monitoring requirements vary. Most permits require qualitative monitoring to be
performed during a "representative storm event" or during a "measureable storm event." However,
some permits do not have this requirement. Please refer to these definitions, if applicable.
A "representative storm event" is a storm event that measures greater than 0.1 inches of rainfall
and that is preceded by at least 72 hours (3 days) in which no storm event measuring greater than
0.1 inches has occurred. A single storm event may contain up to 10 consecutive hours of no
precipitation.
A "measurable storm event" is a storm event that results in an actual discharge from the
permitted site outfall. The previous measurable storm event must have been at least 72 hours
prior. The 72-hour storm interval does not apply if the permittee is able to document that a shorter
interval is representative for local storm events during the sampling period, and the permittee
obtains approval from the local DWQ Regional Office.

FLAGS/NOTES AND DEFINITIONS
B The analyte was detected in the associated method blank.
D The sample was analyzed at dilution.
] The reported value is between the laboratory method detection limit (MDL) and the laboratory method
reporting limit (MRL), adjusted for actual sample preparation data and moisture content, where applicable.
U The analyte was analyzed for but not detected to the level shown, adjusted for actual sample preparation
data and moisture content, where applicable.
E The concentration indicated for this analyte is an estimated value above the calibration range of the
instrument. This value is considered an estimate.
MRL Method Reporting Limit. The MRL is roughly equivalent to the practical quantitation limit (PQQ and is
based on the low point of the calibration curve, when applicable, sample preparation factor, dilution
factor, and, in the case of soil samples, moisture content.
N The analysis indicates the presence of an analyte for which there is presumptive evidence (85% or greater
confidence) to make a "tentative identification".
P Greater than 2511/o concentration difference was observed between the primary and secondary GC column.
The lower concentration is reported.
3-04 Result may be biased high. Associated calibration verification standard exceeded the upper
control limit.
QM-07 The spike recovery was outside acceptance limits for the MS and/or MSD. The batch was
accepted based on acceptable LCS recovery.
QM-11 Precision between duplicate matrix spikes of the same sample was outside acceptance limits.
QV-01 The associated continuing calibration verification standard exhibited high bias; since the result is
ND, there is no impact.
FINAL. This report relates only to the sample as received by the laboratory, and may only be reproduced in full. Page 21 of 23

Tier Three -- Copper/Zinc
To Whom It may Concern,
In regards to our COC Number NCG030447, it has become apparent that we are now in Tier III
due to sample results that show our copper levels are above benchmark for the fourth time during
the term of this permit. On February 241" of 2016 Caterpillar Sanford and Clayton EHS staff
contacted Ken Pickle to discuss previous actions, future plans and to seek guidance for both zinc
and copper.
Since the discovery of benchmark exceedances in copper and zinc we have had many discussions
with a range of Caterpillar staff, including upper management, and Divisional EHS staff. Both
internal and external housekeeping efforts have been improved, products that contain both
constituents have been tracked, and stormdrain filters and socks have been strategically deployed
to slow the exposure of metals. One staff member also attended the recent NCMA Annual Water
Quality Compliance Workshop.
We have been, and continue to, perform monthly sampling due to our previous Tier Two status.
Unfortunately there are not enough data points from samples to satisfy a conclusion of
improvement or solution from these efforts. Any assistance would be appreciated. To date we
have had the last two month's samples come back under benchmark for copper and zinc. Our
plan, if the March sample comes back under benchmark, is to return to biannual sampling. We
would sample in June and then again in the September -November timeframe.
As we discussed with Ken we will be diligent in preventing and controlling this exposure via
process and/or engineering improvements that are within technical and financial means.
If you have any questions, please do not hesitate to call me.

To Whom It may Concern,
December 19, 2016
Please find attached (COC Number NCG030447) our Semi -Annual Stormwater Discharge
Monitoring Report for Caterpillar located at 5000 Womack Rd., Sanford, NC. Upon reviewing
the report you will notice that our outfall location is above the benchmark range for copper and
zinc which requires us to perform a "Tier One" according to the permit.
We have conducted a stormwater inspection of our facility since the sampling period and have
potentially identified some possible causes of the exceedance of the established benchmark. We
will implement some operational control measures for the parameter's of concern, with the
anticipation of bringing the concentration's within regulatory limit.
If you have any questions, please do not hesitate to call me.

❑'Xes ❑ No
Please verify whether Qualitative Monitoring must be performed during a "representative storm
event" or "measureable storm event" (requirements vary, depending on the permit).
Qualitative monitoring requirements vary. Most permits require qualitative monitoring to be
performed during a "representative storm event" or during a "measureable storm event." However,
some permits do not have this requirement. Please refer to these definitions, if applicable.
A "representative storm event" is a storm event that measures greater than 0.1 inches of rainfall
and that is preceded by at least 72 hours (3 days) in which no storm event measuring greater than
0.1 inches has occurred. A single storm event may contain up to 10 consecutive hours of no
precipitation.
A "measurable storm event" is a storm event that results in an actual discharge from the
permitted site outfall. The previous measurable storm event must have been at least 72 hours
prior. The 72-hour storm interval does not apply if the permittee is able to document that a shorter
interval is representative for local storm events during the sampling period, and the permittee
obtains approval from the local DWQ Regional Office.

FLAGS/NOTES AND DEFINITIONS
B The analyte was detected in the associated method blank.
D The sample was analyzed at dilution.
] The reported value is between the laboratory method detection limit (MDQ and the laboratory method
reporting limit (MRL), adjusted for actual sample preparation data and moisture content, where applicable.
U The analyte was analyzed for but not detected to the level shown, adjusted for actual sample preparation
data and moisture content, where applicable.
E The concentration indicated for this analyte is an estimated value above the calibration range of the
instrument. This value is considered an estimate.
MRL Method Reporting Limit. The MRL is roughly equivalent to the practical quantitation limit (PQQ and is
based on the low point of the calibration curve, when applicable, sample preparation factor, dilution
factor, and, in the case of soil samples, moisture content.
N The analysis indicates the presence of an analyte for which there is presumptive evidence (85% or greater
confidence) to make a "tentative identification".
P Greater than 25% concentration difference was observed between the primary and secondary GC column.
The lower concentration is reported.
QL-02 The associated laboratory control sample exhibited high bias; since the result is ND, there is no
impact.
QM-07 The spike recovery was outside acceptance limits for the MS and/or MSD. The batch was
accepted based on acceptable LCS recovery.
QM-11 Precision between duplicate matrix spikes of the same sample was outside acceptance limits.
QR-02 The RPD result exceeded the QC control limits; however, both percent recoveries were
acceptable. Sample results for the QC batch were accepted based on percent recoveries and
completeness of QC data.

FLAGS/NOTES AND DEFINITIONS
B The analyte was detected in the associated method blank.
D The sample was analyzed at dilution.
I The reported value is between the laboratory method detection limit (MDL) and the laboratory method
reporting limit (MRL), adjusted for actual sample preparation data and moisture content, where applicable.
U The analyte was analyzed for but not detected to the level shown, adjusted for actual sample preparation
data and moisture content, where applicable.
E The concentration indicated for this analyte is an estimated value above the calibration range of the
instrument. This value is considered an estimate.
MRL Method Reporting Limit. The MRL is roughly equivalent to the practical quantitation limit (PQL) and is
based on the low point of the calibration curve, when applicable, sample preparation factor, dilution
factor, and, in the case of soil samples, moisture content.
N The analysis indicates the presence of an analyte for which there is presumptive evidence (85% or greater
confidence) to make a "tentative identification".
Greater than 25% concentration difference was observed between the primary and secondary GC column.
The lower concentration is reported.
3-04 Result estimated, calibration verification standard failed with high bias.
QM-07 The spike recovery was outside acceptance limits for the MS and/or MSD. The batch was
accepted based on acceptable LC5 recovery.
QM-11 Precision between duplicate matrix spikes of the same sample was outside acceptance limits.
QV-01 The associated continuing calibration verification standard exhibited high bias; since the result is
MD, the impact on data quality is minimal.

Please find attached (COC Number NCG030447) our monthly Stormwater Discharge
Monitoring Report for Caterpillar located at 5000 Womack Rd., Sanford, NC. We are currently
performing monthly sampling due to our Tier Two status with our Copper readings.
Attached are the November and December stormwater discharge results. You will notice that our
November results came back below the benchmarks for both Copper and Zinc. However, our
December results show elevated readings for both Copper and Zinc when compared to the
benchmarks. As a result, we continue to be Tier One for Zinc and Tier Two for Copper. We
will continue to perform a "Tier One" monitoring for Zinc according to the permit and "Tier
Two' monitoring for Copper according to the permit.
Tier One -- Zinc
We have conducted a stormwater inspection of our facility recently and continue to be confident
that we know the cause of the zinc exceedance of the established benchmark. We continue to
implement operational and procedural changes and have installed engineered controls for the
parameter of concern (zinc), with the anticipation of bringing the concentration within regulatory
limit.
Tier Two - Copper
We have conducted a stormwater walk with the Plant Manager of our facility since the sampling
period and are confident that we know the sources of the copper benchmark exceedance. We
have implemented monthly sample monitoring. We have recently installed metal filtering socks
and filters around select storm drains. We have updated procedures to reduce external exposure
from any shot blast media or waste. These actions have been implemented with the anticipation
of bringing the concentration within regulatory limit.

If you have any questions, please do not hesitate to call me.

FLAGS/NOTES AND DEFINITIONS
B The analyte was detected in the associated method blank.
D The sample was analyzed at dilution.
J The reported value is between the laboratory method detection limit (MDL) and the laboratory method
reporting limit (MRL), adjusted for actual sample preparation data and moisture content, where applicable.
U The analyte was analyzed for but not detected to the level shown, adjusted for actual sample preparation
data and moisture content, where applicable.
E The concentration indicated for this analyte is an estimated value above the calibration range of the
instrument. This value is considered an estimate.
MRL Method Reporting Limit. The MRL is roughly equivalent to the practical quantitation limit (PQL) and is
based on the low point of the calibration curve, when applicable, sample preparation factor, dilution
factor, and, in the case of soil samples, moisture content.
N The analysis indicates the presence of an analyte for which there is presumptive evidence (85% or greater
confidence) to make a "tentative identification".
Greater than 25% concentration difference was observed between the primary and secondary GC column.
The lower concentration is reported.
QL-02 The associated laboratory control sample exhibited high bias; since the result is ND, the impact
on data quality is minimal.
QM-07 The spike recovery was outside acceptance limits for the MS and/or MSD. The batch was
accepted based on acceptable LCS recovery.
QM-11 Precision between duplicate matrix spikes of the same sample was outside acceptance limits.
QM-12 Precision between duplicate samples was outside acceptance limits.

FLAGS/NOTES AND DEFINITIONS
B The analyte was detected in the associated method blank.
D The sample was analyzed at dilution.
] The reported value is between the laboratory method detection limit (MDQ and the laboratory method
reporting limit (MRL), adjusted for actual sample preparation data and moisture content, where applicable.
U The analyte was analyzed for but not detected to the level shown, adjusted for actual sample preparation
data and moisture content, where applicable.
E The concentration indicated for this analyte is an estimated value above the calibration range of the
instrument. This value is considered an estimate.
MRL Method Reporting Limit. The MRL is roughly equivalent to the practical quantitation limit (PQQ and is
based on the low point of the calibration curve, when applicable, sample preparation factor, dilution
factor, and, in the case of soil samples, moisture content.
N The analysis indicates the presence of an analyte for which there is presumptive evidence (85% or greater
confidence) to make a "tentative identification".
Greater than 25% concentration difference was observed between the primary and secondary GC column.
The lower concentration is reported.
3-04 Result estimated, calibration verification standard failed with high bias.
QM-07 The spike recovery was outside acceptance limits for the MS and/or MSD. The batch was
accepted based on acceptable Li recovery.
QM-11 Precision between duplicate matrix spikes of the same sample was outside acceptance limits.
QV-01 The associated continuing calibration verification standard exhibited high bias; since the result is
ND, the impact on data quality is minimal.

1 Monthly sampling (instead of semi-annual) must begin with the second consecutive benchmark exceedance for the same parameter at the same outfall.
'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.
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: 11/1/2012-10/31/2017 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."

Tier One — Zinc Tier 'fwo - Copper
To Whom It may Concern,
November 24, 2015
Please find attached (COC Number NCG030447) our Semi -Annual Stormwater Discharge
Monitoring Report for Caterpillar located at 5000 Womack Rd., Sanford, NC. I received official
lab results on November 12, 2015. Upon reviewing the report you will notice that our outfall
location is slightly above the benchmark range for zinc which requires us to perform a "Tier
One" according to the permit. You will also notice that our outfall location is above the
benchmark range for copper for the second consecutive which requires us to perform "Tier Two'
according to the permit.
Tier One — Zinc
We have conducted a stormwater inspection of our facility since the sampling period and are
confident that we know the cause of the zinc exceedance of the established benchmark. We will
implement some operational and procedural changes and install engineered controls for the
parameter of concern (zinc), with the anticipation of bringing the concentration within regulatory
limit.
Tier Two - Copper
We have conducted a stormwater walk with the Plant Manager of our facility since the sampling
period and are more confident that we know the sources of the copper benchmark exceedance.
We have implemented monthly sample monitoring. We are also in the process of ordering metal
filtering socks and filters for select storm drains. We are updating procedures to reduce external
exposure from any shot blast media or waste. These actions are being implemented with the
anticipation of bringing the concentration within regulatory limit.

If you have any questions, please do not hesitate to call me.

FLAGS/NOTES AND DEFINITIONS
B The analyte was detected in the associated method blank.
D The sample was analyzed at dilution.
] The reported value is between the laboratory method detection limit (MDL) and the laboratory method
reporting limit (MRL), adjusted for actual sample preparation data and moisture content, where applicable.
U The analyte was analyzed for but not detected to the level shown, adjusted for actual sample preparation
data and moisture content, where applicable.
E The concentration indicated for this analyte is an estimated value above the calibration range of the
instrument. This value is considered an estimate.
MRL Method Reporting Limit, The MRL is roughly equivalent to the practical quantitation limit (PQQ and is
based on the low point of the calibration curve, when applicable, sample preparation factor, dilution
factor, and, in the case of soil samples, moisture content.
N The analysis indicates the presence of an analyte for which there is presumptive evidence (85% or greater
confidence) to make a "tentative identification"
Greater than 25% concentration difference was observed between the primary and secondary GC column.
The lower concentration is reported.
3-02 Result is estimated due to bias in the associated laboratory control sample (LCS).
QL-02 The associated laboratory control sample exhibited high bias; since the result is ND, the impact
on data quality is minimal.
QM-07 The spike recovery was outside acceptance limits for the MS and/or MSD. The batch was
accepted based on acceptable LCS recovery.
QM-li Precision between duplicate matrix spikes of the same sample was outside acceptance limits.

z 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/l/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 orareas 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."

Please find attached (COC Number NCG030447) our Semi -Annual Stormwater Discharge
Monitoring Report for Caterpillar located at 5000 Womack Rd., Sanford, NC. Upon reviewing
the report you will notice that our outfall location is slightly above the benchmark range for
copper which requires us to perform a "Tier One" according to the permit.
We have conducted a stormwater inspection of our facility since the sampling period and have
potentially identified some possible causes of the exceedance of the established benchmark. We
will implement some operational control measures immediately for the parameter of concern,
with the anticipation of bringing the concentration within regulatory limit.
If you have any questions, please do not hesitate to call me.

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).
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 fast 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."

FLAGS/NOTES AND DEFINITIONS
B The analyte was detected in the associated method blank.
D The sample was analyzed at dilution.
] The reported value is between the laboratory method detection limit (MDL) and the laboratory method
reporting limit (MRL), adjusted for actual sample preparation data and moisture content, where applicable.
U The analyte was analyzed for but not detected to the level shown, adjusted for actual sample preparation
data and moisture content, where applicable.
E The concentration indicated for this analyte is an estimated value above the calibration range of the
instrument. This value is considered an estimate.
MRL Method Reporting Limit. The MRL is roughly equivalent to the practical quantitation limit (PQL) and is
based on the low point of the calibration curve, when applicable, sample preparation factor, dilution
factor, and, in the case of soil samples, moisture content.
N The analysis indicates the presence of an analyte for which there is presumptive evidence (85% or greater
confidence) to make a "tentative identification".
Greater than 25% concentration difference was observed between the primary and secondary GC column.
The lower concentration is reported.
1-02 Result is estimated due to bias in the associated laboratory control sample (LCS).
3-04 Result estimated, calibration verification standard failed with high bias.
QL-02 The associated laboratory control sample exhibited high bias; since the result is ND, the impact
on data quality is minimal.
QM-07 The spike recovery was outside acceptance limits for the MS and/or MSD. The batch was
accepted based on acceptable LCS recovery.
QM-11 Precision between duplicate matrix spikes of the same sample was outside acceptance limits.
QR-02 The RPD result exceeded the QC control limits; however, both percent recoveries were
acceptable. Sample results for the QC batch were accepted based on percent recoveries and
completeness of QC data.
QV-01 The associated continuing calibration verification standard exhibited high bias; since the result is
ND, the impact on data quality is minimal.
FINAL This report relates only to the sample as received by the laboratory, and may only be reproduced in full. Page 21 of 22
