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.
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."

Total Event Precipitation (inches):
All permits require qualitative monitoring to be performed during a "measurable storm event."
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 DEMLR Regional Office.
By this signature, -I certify that this ryport is accurate and complete to the best of my knowledge:

CIRCOR Pumping Technologies — Monroe, NC
Shield Project No. 1150109-02
Dear Mr. Wallace:
Shield Engineering, Inc. (Shield) successfully collected a monthly stormwater sample for Stormwater
Discharge Outfall (SDO) 9004 at the CIRCOR Pumps North America LLC — Monroe facility for the
month of November 2018. The rainfall pH was measured at 73. Total event precipitation was 1.69
inches. In addition to collection of samples, Shield performed Qualitative Monitoring at SDO #004
(attached). Shield has prepared the Stormwater Discharge Monitoring Report (DMR) using the results of
analyses from the commercial laboratory that the CIRCOR facility has contracted with and the field
values indicated above. The attached DMR should be signed by CIRCOR's authorized representative and
then two signed copies of the DMR form should be mailed to the regulatory agency's Central Files.
During the November 12, 2018 sampling event, the laboratory measurements of Total Recoverable
Copper and Total Recoverable Zinc exceeded the benchmarks with values of 0.0248 mg/L and 0.133
mg/L respectively. Approximately 87% of samples analyzed for Copper since February 2016 have shown
benchmark exceedances. However, the percent exceedance for Copper began a downward trend in April
of 2017 though spiked in February of 2018. March of 2018 showed a decreased concentration of Copper
closer to the benchmark value, but Copper concentration has been on an upward trend to present day.
Zinc concentrations have exceeded the benchmark approximately 47% since February 2016. In February
2017 the Zinc benchmark was exceeded with a concentration of 0.0863 mg/L and bordered above and
below the benchmark until February of 2018 with an exceeding concentration of 0.198 mg/L. March and
April of 2018 showed decreasing concentrations with a slight upwards spike in November 2018. It is
important to note that there were no qualifying events from the months of May through October of 2018
and samples could not be collected. Also, effective November 1, 2018, the benchmarks for copper and
zinc increased to 0.01 mg/L and 0.126 mg/L respectively. The attached compliance tracking spreadsheet
summarizes the analytical results. Please note that Shield began stormwater sampling at the facility in
February 2016. Once the facility experiences a rain event that allows Shield to conduct Tier 3 sampling
beginning early in the day, Shield will have additional data to evaluate and make recommendations for
improvements.in reaching and maintaining benchmark values. Good housekeeping should continue to be
routinely emphasized in addition to any further recommendations that Shield will be making following
the Tier 3 evaluation.

CIRCOR remains in Tier Three for Copper and Zinc and remains Tier One for pH. CIRCOR has dropped
from Tier Two to Tier One for Total Suspended Solids. Shield will continue to perform monthly
sampling per Tier Two requirements until instructed to halt by CIRCOR. Shield greatly appreciates the
opportunity to provide environmental services to the CIRCOR. If you have any questions in reference to
this document or require further information, please feel free to contact either of the undersigned at (704)

Shield Project No. 1150109-02
Dear Mr. Wallace:
Shield Engineering, Inc. (Shield) was unable to collect a monthly stormwater sample for Stormwater Discharge
Outfall (SDO) #004 at the CIRCOR Pumps North America LLC — Monroe facility for the month of August
2018. Measurable rainfall events during the month of August 2018 began on August 1 ", August 18`h, and
August 27'h, measuring 0.96 inches, 0.81 inches, and 0.06 inches, respectively. An additional 0.79 inches, 0.29
inches, 0.1.1 inches, 0.22 inches,. 0.20 inches,. 0.16;inches,.0.01 inches, 0.01 inches, 0.46 inches, 0.49-inches, and
1.16 inches. of rainfall weremeasured on August 2"d, August 3d, August 6d', August 7', August 8"', August 10',
August T Ph, August.21 ", August 28d', August 3Od% August 31 ".respectively. Each of these events took place on
the weekend, after normal business hours, within 72 hours of the last qualifying storm event, or did not produce
enough rainfall for discharge. As the seasonal type of storm event is now a high intensity, short duration event,
usually commencing in late afternoon through early evening with little to no notice for preparation, Shield will
continue to monitor daily weather conditions and attempt to continue coordination of appropriate staff and
resources to facilitate adequate sample collection. Per Section 2, Part IV of General Permit No. NCG030000
Shield will attempt to collect a substitute sample and perform a visual assessment during the next qualifying
storm event. CIRCOR — Monroe facility should complete all relevant sections on the Stormwater Discharge
Monitoring Report (DMR)_ The completed DMR form should then be mailed to the regulatory agency's Central

Subject: Monthly Storrwater Sampling -- March 2018
Certificate of Coverage No. NCG030293
CIRCOR — Monroe, NC

Dear Mr. Nixon:
REC1!:
APR 3 p 2018
CEN7-itf.L Ft:
D4��R "1 CT/ON
Shield Engineering, Inc. (Shield) successfully collected a monthly stormwater sample for Stormwater Discharge
Outfall (SDO) #004 at the CIRCOR — Monroe facility for the month of March 2018. During the March 6, 2018
sampling event, Shield's field measurement of pH was 7.9 at SDO #004. Total event precipitation was 0.63
inches. In addition to collection of samples, Shield performed Qualitative Monitoring at SDO 4004 (attached).
Shield has prepared the Stormwater Discharge Monitoring Report (DMR) using the results of analyses from the
commercial laboratory that the CIRCOR facility has contracted with and the field values indicated above. The
attached DMR should be signed by CIRCOR's authorized representative and then two signed copies of the DMR
form should be mailed to the regulatory agency's Central Files.
The sampling results from the March 6th event show that CIRCOR has exceeded benchmark concentrations for
Total Recoverable Copper and Total Recoverable Zinc. CIRCOR remains in Tier Three for Copper and Zinc
and remains in Tier Two for Total Suspended Solids. Shield will continue to perform monthly sampling per
Tier Two requirements until instructed to halt by CIRCOR. Shield greatly appreciates the opportunity to provide
environmental services to the CIRCOR. If you have any questions in reference to this document or require
further information, please feel free to contact either of the undersigned at [phone].
Respectfully,

Shield Project No. 1150109-02 U WR S�CTI�ES
Dear Ms. Israel:
Shield Engineering, Inc. (Shield) successfully collected a monthly stormwater sample for Stormwater Discharge
Outfall (SDO) #004 at the CIRCOR -- Monroe facility for the month of February 2018. During the February 7,
2018 sampling event, Shield's field measurement of pH was 8.9 at SDO 4004. Total event precipitation was
0.56 inches. In addition to collection of samples, Shield performed Qualitative Monitoring at SDO #004
(attached). Shield has prepared the Stormwater Discharge Monitoring Report (DMR) using the results of
analyses from the commercial laboratory that the CIRCOR facility has contracted with and the field values
indicated above. The attached DMR should be signed by CIRCOR's authorized representative and then two
signed copies of the DMR form should be mailed to the regulatory agency's Central Files,
Please note that the analysis for Total Toxic Organics (625 MSSV) was extracted out of holding time. This was
due to the lab diluting the original sample to a point that caused a non -detect result to be over the benchmark due
to the increased reporting limit. The lab re -analyzed the sample at Shield's request and extracted and reported at
a dilution factor which allowed the non -detect results to meet a reporting limit that was within the benchmark
value.
The sampling results from the February 70' event show that CIRCOR has exceeded benchmark concentrations for
Total Recoverable Copper, Total Suspended Solids and Total Recoverable Zinc. CIRCOR remains in Tier Three
for Copper and has re-entered Tier Three for Zinc and remains in Tier Two for Total Suspended Solids. Shield
will continue to perform monthly sampling per Tier Two requirements until instructed to halt by CIRCOR.
Shield greatly appreciates the opportunity to provide environmental services to the CIRCOR. If you have any
questions in reference to this document or require further information, please feel free to contact either of the
undersigned at [phone].

Outfall (SDO) #004 at the CIRCOR — Monroe facility for the month of December 2017. During the December
20, 2017 sampling event, Shield's field measurement of pH was 8.3 at SDO #004. Total event precipitation was
1.27 inches. In addition to collection of samples, Shield performed Qualitative Monitoring at SDO 4004
(attached). Shield has prepared the Stormwater Discharge Monitoring Report (DMR) using the results of
analyses from the commercial laboratory that the CIRCOR facility has contracted with and the field values
indicated above. The attached DMR should be signed by CIRCOR's authorized representative and then two
signed copies of the DMR form should be mailed to the regulatory agency's Central Files.
The sampling results from the December 20'h event show that CIRCOR has exceeded benchmark concentrations
for Total Recoverable Copper. CIRCOR remains in Tier Three for Copper and Tier Two for Total Suspended
Solids; however, since the last three consecutive samples for Zinc have been above the benchmarks, CIRCOR is
no longer in Tier Two for Zinc. Shield will continue to perform monthly sampling per Tier Two requirements
until instructed to halt by CIRCOR. Shield greatly appreciates the opportunity to provide environmental services
to the CIRCOR. If you have any questions in reference to this document or require further information, please
feel free to contact either of the undersigned at [phone].

2For 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).

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 taxic 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."

All permits require qualitative monitoring to be performed during a "measurable storm event."
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 DEMLR 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.
I certify thattghis report is accurate and complete to the best of my knowledge:

"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."

Subject: Monthly Stormwater Sampling — August 2017
Certificate of Coverage No: NCG030293�
Colfax/IMO Industries — Monroe, NC
Shield Project No. 1150109-02
Dear Ms. Israel:
Shield Engineering, Inc. (Shield) was unable to collect a -monthly stormwater sample for Stormwater Discharge
Outfall (SDO) #004 at the Colfax — Monroe facility for the month of August 2017. Shield did mobilize towards
the facility and attempt to collect a sample on August 31; however, the rain did not produce a discharge from
the facility during business hours. Shield was able to collect a sample for September. The September sampling
results and reports will be submitted under separate cover once results are received from the laboratory.
Measurable rainfall events during the month of August 2017 began on August 7`h, August 22'd, and August 29h,
each measuring 0.68 inches, 0.17 inches, and 0.01 inches, respectively on those days. An additional 0.10 inches,
0.31 inches, 0.95 inches, 0.12 inches, 0.66 inches, 0.12 inches, 0.05 inches, 0.14 inches, 0.15 inches, 0.11 inches,
and 1.25 inches of rain were measured on August 8`h, August I Ith, August 120', August 13`h, August 10, August
15`h, August 171h, August 18`h, August 23`d, August 24`h, and August 31", respectively. Each of these events
took place on the weekend, after normal business hours, or within 72 hours of the last qualifying storm event.
As the seasonal type of storm event is now expected to change to high intensity, short duration events, usually
commencing in late afternoon through early evening with little to no notice for preparation, Shield will continue
to monitor daily weather conditions and attempt to continue coordination of appropriate staff and resources to
facilitate adequate sample collection. Per Section 2, Part IV of General Permit No. NCG030000 Shield will
attempt to collect a substitute sample and perform a visual assessment during the next qualifying storm event.
Colfax — Monroe facility should complete all relevant sections on the Stormwater Discharge Monitoring Report
(DMR). The completed DMR form should then be mailed to the regulatory agency's Central Files.
Shield will continue to attempt to perform monthly sampling per Tier Two requirements until instructed to halt
by Colfax. Shield greatly appreciates the opportunity to provide environmental services to the Colfax/IMO
Industries. If you have any questions in reference to this document or require further information, please feel free
to contact either of the undersigned at [phone].
