Dear Mr. Mirecki:
Shield Engineering, Inc. (Shield) successfully collected a monthly stormwater sample for Stormwater Discharge
Outfall (SDO) #004 at the CIRCOR Pumps North America LLC — Monroe facility on March 31, 2021. The pH
was measured at 6.3 at SDO 4004. Total event precipitation was 0.03 inches. In addition to the 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
person designated to act as the permittee by CIRCOR Pumping Technologies — Monroe facility should sign page
1 of the DMR. The signed DMR form should then be mailed to the regulatory agency regional office at
Mooresville, NC.
The sampling results from the March 3 1 " event show that CIRCOR has an exceedance of Copper at outfall #004.
CIRCOR remains in Tier Three for Copper and Zinc at SDO #004. Shield will continue to perform monthly
sampling for SDO #004 per Tier Two requirements until instructed to malt 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
