To Whom It May Concem:
Attached please find the Stormwater Discharge Monitoring Report (DMR) and analytical
report for the sampling conducted at the above -referenced site. A stormwater sample was
collected from Outfall 001 on December 12, 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. 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 D, Table II of Chapter 40 Code of Federal Regulations (CFR) Part 122.

Attached please find the Stormwater Discharge Monitoring Report (DMR) and analytical
report for the sampling conducted at the above -referenced site. A stormwater sample was
collected from Outfall 001 on April 24, 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. 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 5-9.
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 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."

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. headings 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 II of Chapter 40 Code of Federal Regulations (CFR) Part 122.

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.
15ee 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 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.
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.
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 i &o 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.

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

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."

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 II of Chapter 40 Code of Federal Regulations (CFR) Part 122.

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."

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 II of Chapter 40 Code of Federal Regulations (CFR) Part 122.

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),
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."
