To Whom It May Concern:
„Circor has recently undergone a personnel change within its EHS department. Upon review of our records, it is unclear if
the stormwater discharge monitoring reports (DMRs) from January -July 2019 were received by Central
Files. Therefore, we have included copies of those DMRs along with the submittal of our August 2019 DMR.

DWR SECTION
Shield Engineering, Inc. (Shield) successfully collected a monthly stormwaler sample for Stormwater Discharge
Outfall (SDO) #004 at the CIRCOR Pumps North America LLC — Monroe facility for the month of January
2019. The pl-I at SDO #004 was measured at 8.5. Total event precipitation was 0.1 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.
i
During the January 29, 2019 sampling event, the laboratory measurements of Total Recoverable Copper and
Total Recoverable Zinc indicated concentrations within the benchmark values. CIRCOR remains in Tier Three
for Copper and 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].

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 m and the perlttee
obtains approval from, the local DEMLR Regional Office.

Rich Wallace, Senior Manager, EH&S
CIRCOR Pumps North America LLC
1710 Airport Road
Monroe, North Carolina 28110
Subject: Monthly Stormwater Sampling —February 2019
Certificate of Coverage No. NCG030293
CIRCOR Pumping Technologies — Monroe, NC
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 February
2019. According to rainfall data collected for the month, there were no qualifying rainfall events as defined by
General Permit No. NCG030000. The first rainfall event of the month began on February 10h and extended
through February 12`h, producing a total of 0.7.2 inches of rain. Rain began again on February 16'h and extended
through the end of February, February 28'h. This rain event totaled 5.14 inches of rain. Both 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 to collect a sample. Shield will continue to monitor daily weather conditions and
attempt to continue coordination of appropriate staff and resources to facilitate adequate sample collection.
Shield was able to collect a sample for the month of March. 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

Certificate of Coverage No. NCG030293
CIRCOR Pumping Technologies — Monroe, NC
Shield Project No. 1150109-02
Dear Mr. Wallace:
Shield Engineering, Inc. (Shield) successfully collected a monthly stormwaler sample for Stormwater Discharge
Outfall (SDO) 4004 at the CIRCOR Pumps North America LLC — Monroe facility for the month of March 2019.
The pl I at SDO #004 was measured at 8.5. Total event precipitation was 0.5 inches. In addition to collection of
samples, Shield performed Qualitative Monitoring at SDO 9004 (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 March 8, 2019 sampling event, the laboratory measurement of Total Recoverable Zinc and Total
Recoverable Copper indicated concentrations within the benchmark values. CIRCOR remains in Tier Three for
Copper and 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].

A "measurable storm event' is a storm event that results in an actual discharge from the
permitted site outfall. 'rhe previous measurahle storm event must have been at least 72 hours
prior. The 72-11ourr 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 DGMLR Regional Office.

Subject: Monthly Stormwater Sampling — April 2019
Certificate of Coverage No. NCG030293
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 April 2019.
The pH at SDO #004 was measured at 8.2. Total event precipitation was 0.1 inches. In addition to collection of
samples, Shield performed Qualitative Monitoring at SDO 9004 (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 April 2"d event show that CIRCOR has exceeded the benchmark concentration for
Total Recoverable Copper. CIRCOR remains in Tier Three for Copper and 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 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].

s Total Toxic Organics sampling is applicable only for those facilities which perform metal finishing operations, manufacture semiconductors, manufacture
electronic crystals, or manufacture cathode ray tubes. For purposes of this permit the definition of Total Toxic Organics is that definition contained in the EPA
Effluent Guidelines for the facility subject to the requirement to sample (for metal finishing use the definition as found in 40 CFR 433.11; for semiconductor
manufacture use the definition as found in 40 CFR 469.12; for electronic crystal manufacture use the definition as found in 40 CFR 469.22; and for cathode ray
tube manufacture use the definition found in 40 CFR 469.31).

Facilities that incorporate a solvent management plan into the Stormwater Pollution Prevention Plan may so certify, and the requirement for TTO monitoring
may be waived. The solvent management plan shall include a list of the total toxic organic compounds used and the other elements listed in the General
Permit. For those facilities electing to employ the TTO monitoring waiver, the discharger shall sign the following certification statement:
"Based upon my inquiry of the person or persons directly responsible for managing compliance with the permit monitoring requirement for total toxic organics
(TTO), 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."

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.

CIRCOR Pumping Technologies — Monroe, NC
Shield Project No. 1150109-02
Dear Mr. Wallace:
Shield Engineering, Inc. (Shield) was unable to collect a monthly slormwater sample for Stormwater Discharge
Outfall (SDO) 4004 at the CIRCOR Pumps North America LLC — Monroe facility for the month of May 2019.
According to rainfall data collected for the month, there were no qualifying rainfall events as defined by General
Permit No. NCG030000. The only rainfall event of the month began on May 4" and extended May 11'h,
producing a total of 2.48 inches of rain. This rain event began on the weekend or after normal business hours.
Shield will continue to monitor daily weather conditions and attempt to continue coordination of appropriate
staff and resources to facilitate adequate sample collection. Shield was able to collect a sample for the month of
June. 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 Files.
Shield will continue to attempt 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
Pumps North America LLC. 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].

Dear Mr. Wallace:
Shield Engineering, Inc. (Shield) successfully collected a monthly stormwater sample for Stormwater Discharge
Outfall (SDO) 4004 at the CIRCOR Pumps North America LLC — Monroe facility for the month of June 2019.
The pl-I at SDO 9004 was measured at 8.9. Total event precipitation was 1.12 inches. In addition to collection
of samples, Shield performed Qualitative Monitoring at SDO 9004 (attached). During the Qualitative
Monitoring, an oil sheen and odor was observed at SDO #004. An Industrial Facility Inspection was
immediately conducted and a source of the sheen and odor was not found. 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 June 7th event show that CIRCOR has exceeded the benchmark concentration for
Total Recoverable Copper and Non -Polar Oil and Grease. CIRCOR remains in Tier Three for Copper and 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 CIRCOR. if you have
any questions in reference to this document or require further information, please feel free to contact either of the

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."

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.

Dear Mr. Wallace:
Shield Engineering, Inc. (Shield) was unable to collect a monthly stormwater sample for Stormwater Discharge
Outfall (SDO) 4004 at the CIRCOR Pumps North America LLC — Monroe facility for the month of July 2019.
According to rainfall data collected for the month; there were no qualifying rainfall events as defined by General
Permit No. NCG030000. The rainfall events for the month began on July I I", July 19" and July 31", producing
a total of 2.17 inches, 2.28 inches, and 0.20 inches of rain, respectively. Each of these rain events began on the
weekend or after normal business hours. Shield will continue to monitor daily weather conditions and attempt to
continue coordination of appropriate staff and resources to facilitate adequate sample collection. 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 Files.
Shield will continue to attempt 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
Pumps North America LLC. 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].
