Dear Mr. Lee:
There were no qualifying rainfall events for the month of October 2022 as defined by General Permit No.
NCG030000.As a result,no monthly stormwater samples were collected for Stormwater Discharge Outfall
(SDO)#004 at the CIRCOR Pumps North America LLC—Monroe facility this month. According to rainfall
data' collected for the month, three rain events or group events occurred on October 1st,October 126,
and October 30th,producing 0.09 inches,0.05 inches,and 1.06 inches of rain, respectively. However,each
of these events took place after normal business hours, within 72 hours of the last rain event, or did not
produce enough rainfall to collect a sample. Shield will continue to monitor daily weather conditions and
attempt coordination of appropriate staff and resources to facilitate adequate sample collection. A
partially completed Discharge Monitoring Report form is attached to this cover letter for signature of the
appropriate authorized permittee and submittal to the State.
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(704)394-6913.
