Title	Offsite Notification Due to Exceeding NPDES Limit
Event Description	While preparing for the June 2021 Discharge Monitoring Report (DMR), Environmental was entering data per the lab results that were sent from Pace Analytical for the June DMRs. On June 1, 2021, a National Pollutant Discharge Eliminating System (NPDES) sample was collected at outfall 001A to test for copper, there is a NPDES permit condition to monitor for copper on a quarterly basis. The lab report was returned to Fermi Environmental on June 15, 2021. The results came back at 41.2 micrograms/liter. Fermi's NPDES permit maximum limit is 40 micrograms/liter for outfall 001A. Due to the June 1, 2021 sample exceeding the permit limit, a second sample was collected on June 21, 2021 as a verification sample and the copper results came back July 13, 2021. Those results came back at 5.9 micrograms/liter which is within the permit limit. Environmental was aware of the June 1, 2021 copper exceedance limit but failed to recognize the reporting requirement at the time of the discovery because it was thought that the exceedance would be reported through the DMR submittal. The June DMRs are due on July 20, 2021. At approximately 1740 EDT on July 15, 2021, a Fermi environmental engineer was preparing and reviewing the Discharge Monitoring Report and identified that a recent sample result for outfall 001A was outside of the NPDES permit limit for Copper. The Copper sample result was 41.2 micrograms/liter with a limit of 40 micrograms/liter. Subsequent discussions with Environmental personnel determined that this issue should be reported to the state of Michigan Department of Environment, Great Lakes and Energy (EGLE). A discussion is planned with EGLE on July 16, 2021. This notification is being made pursuant to 10 CFR 50.72(b)(2)(xi) based on the planned notification to EGLE. The licensee notified the NRC Resident Inspector. * * UPDATE ON 07/22/2021 AT 2141 FROM MARGARET OFFERLE TO OSSY FONT * * * The licensee initially reported the lab report was returned to Fermi Environmental on June 15, 2021. The date of receipt was June 16, 2021. The licensee will notify the NRC Resident Inspector. Notified R3DO (Pelke).
