Dear Mr. Mirecki:
Shield Engineering, Inc. (Shield) successfully collected a monthly stormwater sample for Stormwater
Discharge Outfall (SDO) #004 and a quarterly stonnwater sample for Stormwater Discharge Outfall (SDO)
#005 at the CIRCOR Pumps North America LLC — Monroe facility on October 8, 2021. The pH was
measured at 6.3 and 6.8 at SDO #004 and SDO #005, respectively, and the total event precipitation was
0.71 inches. In addition to the collection of samples, Shield performed Qualitative Monitoring at SDO
4004 and SDO #005. The Qualitative Monitoring Report for SDO #005 notes that the pipe has collapsed,
and stormwater is flowing around the pipe. This has caused a small amount of erosion around the left side
of the pipe. Furthermore, TSS values have increased during the last three sampling events at SDO #005,
and the benchmark could be exceeded if no corrective actions are taken. 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
October 8' event show that there were no exceedances at either outfall.
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,
