Stormwater Sampling—February 2024
NPDES General Permit No. NCG030000/CoC No. NCG030293
Dear Mr.Lee,
CDG, Inc. (CDG) successfully collected stormwater samples for Stormwater
Discharge Outfalls SDO #004 and SDO #005 at the CIRCOR Pumps North
America LLC — Monroe facility for the month of February 2023. During the
February 23`d sampling event, CDG's field measurements of pH were 7.6 at
SDO #004 and 7.2 at SDO #005. The analytical results of the stormwater
samples collected during the qualifying storm events are attached to this cover
letter. In addition, the Qualitative Monitoring Reports (QMR) and the partially
completed Discharge Monitoring Report(DMR)are attached to this cover letter.
The QMRs should be kept onsite. Analytical results from the sampling event
show an exceedance of Copper at SDO #004.No exceedances were detected in
SDO #005.
CIRCOR remains in Tier Three for Copper at SDO #004. CDG 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].
Sincerely,
CDG,Inc.

All permits require qualitative monitoring to be performed during a"measurable storm event."
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 72 hours prior. The 72-hour storm
interval 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 obtains approval from the local DEMLR
Regional Office.
