Shield Project No.1150109-17
Dear Mr. Mirecki:
There were no qualifying rainfall events for the month of April 2021 as defined by General Permit No.
NCG030000. As a result, no monthly stormwater samples were collected for Stormwater Discharge Outfall #004
at the CIRCOR Pumps North America LLC — Monroe facility in April. According to rainfall datat collected for
the month, three rain events or group events occurred on April 10', April 161, and April 22nd' producing 0.06
inches, 0.04 inches and 3.03 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. CIRCOR — Monroe facility should complete all relevant
sections on the Stormwater Discharge Monitoring Report (I)MR). The completed DMR form should then be
mailed to the regulatory agency regional office at Mooresville, NC.
Shield will continue to attempt to perform monthly sampling per Tier Two requirements until instructed to halt
by CIRCOR. Shield greatly appreciates the opportunity to provide environmental services to the CIRCOR
Pumps North America LLC. If you have any questions in reference to this document or require further
information, please feel free to contact either of the undersigned at [phone].
