Dear Mr. Helms:
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 16,
2022. The pH was measured at 6.1 at SDO #004 and the total event precipitation was 0.34 inches. In
addition to the collection of samples, Shield performed Qualitative Monitoring at SDO #004. 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 sampling results from the March 16" event show that SDO #004 has met benchmark values for this
sampling event.
CIRCOR remains in Tier Three for Copper at SDO #004. 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 the undersigned at [phone].
Respectfully,
SHIELD ENGINEERING, INC.
