Colfax/IMO Industries — Monroe, NC
Shield Project No. 1150109-02
Dear Ms. Baker:
Shield Engineering, Inc. (Shield) was unable to collect stormwater samples for Stormwater
Discharge Outfall (SDO) #004 at the Colfax - Monroe facility for the month of August 2016.
According to rainfall data collected for the month, qualifying storm events occurred on August
5`h, August 18`h, August 27`h, and August 31", measuring 0.30, 0.79, 0.40, and 0.10 inches
respectively. An additional 0.21 and 0.34 inches of rain were measured on August 7`h and
August I01h, respectively. These events took place after normal business hours or within 72
hours of the last qualifying storm event. As the seasonal type of storm event has now changed 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. Shield was able to collect a sample and perform a visual assessment during
the next qualifying storm event which occurred on September 2nd
Colfax - Monroe Facility remains in Tier Three of the NPDES General Permit No. NCG030000.
Shield greatly appreciates the opportunity to provide environmental services to Colfax. 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].

Colfax/IMO Industries — Monroe, NC
Shield Project No. 1150109-02
Dear Ms. Maxwell:
Shield Engineering, Inc. (Shield) successfully collected a monthly stormwater sample for
Stormwater Discharge Outfall (SDO) #004 at the Colfax — Monroe facility for the month of
September 2016. During the September 2, 2016 sampling event, Shield's field measurement of
pH was 8,6 at SDO #004. Total event precipitation was 0.56 inches. In addition to collection of
samples, Shield performed Qualitative Monitoring at SDO #004 (attached). Colfax — Monroe
facility should complete all relevant sections of the Stormwater Discharge Monitoring Report
(DMR) using the results of analyses from the commercial laboratory that the Colfax facility has
contracted with and the field pH value indicated above. The completed DMR form should then
be mailed along with the Qualitative Monitoring Report Form to the regulatory agency's Central
Files.
Shield will continue 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].

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 this signature, I certify that this report is accurate and complete to the best of my knowledge:

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.
'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
Page 1 of 3

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."

Shield Project No. 1150109-02
Dear Mr. Reichert:
RECEIVED
JUN: 16 2016
CENTRAL FILES
DWR SECTION
Shield Engineering, Inc. (Shield) successfully collected a monthly stormwater sample for
Stormwater Discharge Outfall (SDO) #004 at the Colfax — Monroe facility for the month of May.
During the May 17, 2016 sampling event, Shield's field measurement of pH was 7.4 at SDO
#004. Total event precipitation was 0.43 inches. In addition to collection of samples, Shield
performed Qualitative Monitoring at SDO #004 (attached). As discussed between Melinda M.
Greene of Shield and Krista Baker of Colfax on June 7, 2016, Colfax — Monroe facility should
complete all relevant sections of the Stormwater Discharge Monitoring Report (DMR) using the
results of analyses from the commercial laboratory that the Colfax facility has contracted with
and the field pH values indicated above. The completed DMR form should then be mailed along
with the Qualitative Monitoring Report Form to the regulatory agency's Central Files.
Shield will continue 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].
Respectfully,

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.
'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.
4 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

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
11
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.

Dear Mr. Reichert:
Shield Engineering, Inc. (Shield) successfully collected a monthly stormwater sample for
Stormwater Discharge Outfall (SDO) #004 at the Colfax — Monroe Facility for the month of
April. The analytical results of the stonnwater sample collected during a qualifying storm event
on April 1, 2016 are attached to this cover letter. In addition, a completed qualitative monitoring
report and partially completed DMR form are attached to this cover letter. Results from the April
1, 2016 sampling event shows that all of the parameters were below the corresponding
benchmarks.
Colfax - Monroe Facility remains in Tier Three of the NPDES General Permit No. NCG030000.
The person designated to act as the permittee by Colfax - Monroe Facility should complete all
"Red" sections of the attached Stormwater Discharge Monitoring Report (DMR). The completed
DMR form should then be mailed to the regulatory agency Central Files. Shield greatly
appreciates the opportunity to provide environmental services to Colfax. If you have any

Please verify whether Qualitative Monitoring must be performed during a "representative storm

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.

Subject: Monthly Stormwater Sampling— March 2016
Certificate of Coverage No. NCG030293
Colfax/IMO Industries — Monroe, NC
Shield Project No. 1150109-02
Dear Mr. Reichert:
Shield Engineering, Inc. (Shield) successfully collected a monthly storrlwater sample for
Stormwater Discharge Outfall (SDO) #004 at the Colfax — Monroe Facility for the month of
March. The analytical results of the Stormwater sample collected during a qualifying storm event
on March 28, 2016 are attached to this cover letter. In addition, a completed qualitative
monitoring report and partially completed DMR form are attached to this cover letter. Results
from the March 28, 2016 sampling event show an exceedance of the following parameter at or
above the corresponding benchmark:
• SDO #004 (02/03/16) —Copper — 0.0122 mg/L (Benchmark 0.007 mg/L)
Colfax - Monroe Facility remains in Tier Three of the NPDES General Permit No. NCG030000.
The person designated to act as the permittee by Coflax - Monroe Facility should complete all
"Red" sections of the attached Stormwater Discharge Monitoring Report (DMR). The completed
DMR form should then be mailed to the regulatory agency Central Files. Shield greatly
appreciates the opportunity to provide environmental services to Colfax. 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].

® Yes ❑ 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
j permitted site outfall. The previous measurable storm event must have been at least 7Z hours
prior. The 72-hour storm interval does not apply if the permittee is able to document that a shorter i
interval is representative for local storm events during the sampling period, and the permittee
obtains approval from the local DWQ Regional Office.
By this signature, 1 certify Nett this report is accurate and complete to the best of my knowledge:

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."

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 "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 hoes
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 this signature, I certify that.th report is accurate and complete to the best of my knowledge:
