To Whom It May Concern:
Attached please find the Stormwater Discharge Monitoring Report (DMR) and analytical
report for the sampling conducted at the above -referenced site. Stormwater samples
were collected from Outfalls A and B on May 13, 2019 and analyzed for total suspended
solids (TSS), pH, total recoverable lead, oil and grease and ethylene glycol. As indicated
on the attached DMR, all parameters were reported below or within their respective
benchmark values. If you have any questions or need additional information, please
contact me at 919-250-9918.

Note: If you report a sampled value in excess of the benchmark value, or outside the benchmark range for pH, you must implement Tier 1 or Tier 2 responses in the General
Permit,
1See If pH values outside this range are recorded in sampled stormwater discharges, but ambient precipitation pH levels are lower, then the lower threshold of this benchmark
range is the pH of the precipitation (within instrument accuracy)instead of 6 S.U. Readings from an on -site or local rain gauge (or local precipitation data) must be documented
to demonstrate background concentrations were below the benchmark pH range of 6-9.
2See General Permit text to identify whether the more protective benchmark applies for especially sensitive receiving waters.
3For purposes of this permit the definition of Total Toxic Organics is that list as stated in Appendix 0, Table II of Chapter 44 Code of Federal Regulations (CFR) Part 122.

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. 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".
Greater than 25% concentration difference was observed between the primary and secondary GC column,
The lower concentration is reported.
[CALC] Calculated analyte - MDL/MRL reported to the highest reporting limit of the component analyses.
QL-02 The associated laboratory control sample exhibited high bias; since the result is ND, there is no impact.
QR-06 The RPD value for the LCS/LCSD was outside of QC acceptance limits.
QS-03 Surrogate recovery outside acceptance limits

Note: If you report a sampled value in excess of the benchmark value, or outside the benchmark range for pH, you must implement Tier 1 or Tier 2 responses in the General
Permit.
1See If pH values outside this range are recorded in sampled stormwater discharges, but ambient precipitation pH levels are lower, then the lower threshold of this benchmark
range is the pH of the precipitation (within instrument accuracy)instead of 6 S.U. Readings from an on -site or local rain gauge (or local precipitation data) must be documented
to demonstrate background concentrations were below the benchmark pH range of 6-9.
2See General Permit text to identify whether the more protective benchmark applies for especially sensitive receiving waters.
3For purposes of this permit the definition of Total Toxic Organics is that list as stated in Appendix D, Table It of Chapter 40 Code of Federal Regulations (CFR) Part 122,

To Whom It May Concern:
Attached please find the Stormwater Discharge Monitoring Report (DMR) and analytical
report for the sampling conducted at the above -referenced site. Stormwater samples
were collected from Outfalls A and B on May 17, 2018 and analyzed for total suspended
solids (TSS), pH, total recoverable lead, oil and grease and ethylene glycol. As indicated
on the attached DMR, all parameters were reported below or within their respective
benchmark values, with the exception of ethylene glycol. Based on these results, a Tier
One Response has been implemented at the facility and the results documented in the
facility's Stormwater Pollution Prevention Plan (SPPP). If you have any questions or need
additional information, please contact me at 919-250-9918.

Note: If you report a sampled value in excess of the benchmark value, or outside the benchmark range for pH, you must implement Tier 1 or Tier 2 responses in the General
Permit.
1See If pH values outside this range are recorded in sampled stormwater discharges, but ambient precipitation pH levels are lower, then the lower threshold of this benchmark
range is the PH of the precipitation (within instrument accuracy)instead of 6 S.U. Readings from an on -site or local rain gauge (or local precipitation data) must be documented
to demonstrate background concentrations were below the benchmark pH range of 6-9.
25ee General Permit text to identify whether the more protective benchmark applies for especially sensitive receiving waters.
3For purposes of this permit the definition of Total Toxic Organics is that list as stated in Appendix D, Table II of Chapter 40 Code of Federal Regulations (CFR) Part 122.

STORMWATER DISCHARGE OUTFALL (SDO)
MONITORING REPORT
Facilities that incorporate a solvent management plan into the Stormwater Pollution Prevention Plan may request that DWQ waive monitoring of total toxic organics. The solvent
management plan shall include a list of the total toxic organic compounds used and the other elements listed in the General Permit. For those facilities allowed such a waiver, the
discharger shall sign the following certification statement:
Solvent Management Plan 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 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 (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. 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".
Greater than 25% concentration difference was observed between the primary and secondary GC column.
The lower concentration is reported.

To Whom It May Concern:
Attached please find the Stormwater Discharge Monitoring Report (DMR) and analytical
report for the sampling conducted at the above -referenced site. Stormwater samples
were collected from Outfalls A and B on April 6, 2017 and analyzed for total suspended
solids (TSS), pH, oil and grease, ethylene glycol and total recoverable lead. As indicated
on the attached DMR, all parameters were reported below or within their respective
benchmark values, with the exception of oil and grease at Outfall A. Based on the results
of this sampling event, a Tier One Response has been implemented at the facility. If you
have any questions or need additional information, please contact me at 919-250-9918.

Note: if you report a sampled value in excess of the benchmark value, or outside the benchmark range for pH, you must implement Tier 1 or Tier 2 responses in the General
Permit.
ISee If pH values outside this range are recorded in sampled stormwater discharges, but ambient precipitation pH levels are lower, then the lower threshold of this benchmark
range is the pH of the precipitation (within instrument accuracy)instead of 6 S.U. Readings from an on -site or local rain gauge (or local precipitation data) must be documented
to demonstrate background concentrations were below the benchmark pH range of 6-9.
2See General Permit text to identify whether the more protective benchmark applies for especially sensitive receiving waters.
3For purposes of this permit the definition of Total Toxic Organics is that list as stated in Appendix D, Table 11 of Chapter 40 Code of Federal Regulations (CFR) Part 122.

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 (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.
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.
QM-12 Precision between duplicate samples was outside acceptance limits.

Note: If you report a sampled value in excess of the benchmark value, or outside the benchmark range for pH, you must implement Tier 1 or Tier 2 responses in the General
Permit.
ISee If pH values outside this range are recorded in sampled stormwater discharges, but ambient precipitation pH levels are lower, then the lower threshold of this benchmark
range is the pH of the precipitation (within instrument accuracy) instead of 6 S.U. Readings from an on -site or local rain gauge (or local precipitation data) must be documented
to demonstrate background concentrations were below the benchmark pH range of 6-9.
2See General Permit text to identify whether the more protective benchmark applies for especially sensitive receiving waters.
3For purposes of this permit the definition of Total Toxic Organics is that list as stated in Appendix D, Table Il of Chapter 40 Code of Federal Regulations (CFR) Part 122.

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.
QM-07 The spike recovery was outside acceptance limits for the MS and/or MSD. The batch was
accepted based on acceptable LCS recovery.

Attached please find the Stormwater Discharge Monitoring Report (DMR) and analytical
report for the sampling conducted at the above -referenced site. Stormwater samples
were collected from Outfails A and B on November 29, 2016 and analyzed for total
suspended solids (TSS), pH, oil and grease and ethylene glycol (please note that the
samples were not analyzed in the laboratory for total recoverable lead for the current
sampling event). As indicated on the attached DMR, all parameters were reported below
or within their respective benchmark values, with the exception of TSS at Outfall A and Oil
and Grease at Outfall B. Based on these results, a Tier One Response has been
implemented at the facility. Samples will be collected from each outfall during the January
-June 2017 monitoring period and analyzed for TSS, pH, oil and grease, ethylene glycol
and total recoverable lead. If you have any questions or need additional information,
please contact me at 919-250-9918.

Note: If you report a sampled value in excess of the benchmark value, or outside the benchmark range for pH, you must implement Tier 1 or Tier 2 responses in the General
Permit.
1See If pH values outside this range are recorded in sampled stormwater discharges, but ambient precipitation pH levels are lower, then the lower threshold of this benchmark
range is the pH of the precipitation (within instrument accuracy) instead of 6 S.U. Readings from an on -site or local rain gauge (or local precipitation data) must be documented
to demonstrate background concentrations were below the benchmark pH range of 6-9.

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 (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.
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 250/c concentration difference was observed between the primary and secondary GC column.
The lower concentration is reported.
QM-07 The spike recovery was outside acceptance limits for the MS and/or MSD. The batch was
accepted based on acceptable LCS recovery.

Attached please find the Stormwater Discharge Monitoring Report (DMR) and analytical
report for the sampling conducted at the above -referenced site. Stormwater samples
were collected from Outfalls A and B on April 7, 2014 and analyzed for total suspended
solids (TSS), pH, total recoverable lead, oil and grease and ethylene glycol. As indicated
on the attached DMR, all parameters were reported below or within their respective
benchmark values. If you have any questions or need additional information, please

Note: If you report a sampled value in excess of the benchmark value, or outside the benchmark range for pH, you must implement Tier 1 or Tier 2 responses in the General
Permit.
1See If pH values outside this range are recorded in sampled stormwater discharges, but ambient precipitation pH levels are lower, then the lower threshold of this benchmark
range is the pH of the precipitation (within instrument accuracy) instead of 6 S.U. Readings from an on -site or local rain gauge (or local precipitation data) must be documented
to demonstrate background concentrations were below the benchmark pH range of 6-9-
2 See General Permit text to identify whether the more protective benchmark applies for especially sensitive receiving waters.
3For purposes of this permit the definition of Total Toxic Organics is that list as stated in Appendix D, Table 11 of Chapter 40 Code of Federal Regulations (CFR) Part 122.

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 (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".
QM-07 The spike recovery was outside acceptance limits for the MS and/or MSD. The batch was
accepted based on acceptable LCS recovery.

Note: If you report a sampled value in excess of the benchmark value, or outside the benchmark range for pH, you must implement Tier 1 or Tier 2 responses in the General
Permit.
1See If pH values outside this range are recorded in sampled stormwater discharges, but ambient precipitation pH levels are lower, then the lower threshold of this benchmark
range is the pH of the precipitation (within instrument accuracy) instead of 6 S.U. Readings from an on -site or local rain gauge (or local precipitation data) must be documented
to demonstrate background concentrations were below the benchmark pH range of 6-9.
2See General Permit text to identify whether the more protective benchmark applies for especially sensitive receiving waters.
3For purposes of this permit the definition of Total Toxic Organics is that list as stated in Appendix D, Table 11 of Chapter 40 Code of Federal Regulations (CFR) Part 122.

management plan shall include a list of the total toxic organic compounds used and the other elements listed in the General Permit. For those facilities allowed such a waiver, the
discharger shall sign the following certification statement:
Solvent Management Plan 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),
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 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.
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"
P Greater than 25% concentration difference was observed between the primary and secondary GC column.
The lower concentration is reported.
