Dear Mr. Mirecki:
Shield Engineering, Inc. (Shield) successfully collected a monthly storrnwater sample for Stormwater
Discharge Outfall (SDO) #004 at the CIRCOR Pumps North America LLC — Monroe facility on September
21, 2021. The pH was measured at 6.4 at SDO #004 and the total event precipitation was 0.12 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 September 215` event show that CIRCOR has an exceedance of Copper at
Outfall #004.
CIRCOR remains in Tier Three for Copper and Zinc at SDO 4004. 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,
