' 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.
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

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."

Note: Results must be reported in numerical format. Do not report Below Detection Limit, BDL, <PQL, Non -detect, ND, or other similar non -numerical
format. When results are below the applicable limits, they must be reported in the format, "<XX mg/L", where XX is the numerical value of the detection
limit, reporting limit, etc. in mg/L.
(Vote: if you report a sample value in excess of the benchmark, you must implement Tier 1, Tier2, or Tier responses. See General Permit text.

? 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 ?2 hours
prior. The 72-hour storm intervai 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
Lbtains approval from the local DEMLR Regional Office.

Shield Project No. 1150109-02
Dear Mr, Wallace:
O
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 December
2018. The pH at SDO #004 was measured at 8.7. Total event precipitation was 0.79 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 fie: above. ttached DMR should be
signed by CIRCOR's authorized representative and t n two signed copies of the DMR forpilhould be mailed to
the regulatory agency's Central Files.
During the December 14, 2018 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 and remains Tier One for pH. CIRCOR remains in 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 [phone].
Respectfully,
