EN Revision Text: STOLEN TROXLER GAUGE
On July 14, 2021, a technician left a job site unknowingly leaving a Troxler gauge on the tailgate, which subsequently fell off. The project supervisor was informed of the incident at approximately 1445 EDT. A local business has still images of an individual in a truck picking up the gauge on the side of the road and driving off. Local law enforcement was called, and an investigation is underway. The Troxler gauge, model number 35/40, 25423, contained 8 mCi of Cs-137 (serial number 75-8257) and 40 mCi of Am-241:BE (serial number 47-21754). The Transport Index is 0.6.
THIS MATERIAL EVENT CONTAINS A 'Less than Cat 3' LEVEL OF RADIOACTIVE MATERIAL
Sources that are "Less than IAEA Category 3 sources," are either sources that are very unlikely to cause permanent injury to individuals or contain a very small amount of radioactive material that would not cause any permanent injury. Some of these sources, such as moisture density gauges or thickness gauges that are Category 4, the amount of unshielded radioactive material, if not safely managed or securely protected, could possibly - although it is unlikely - temporarily injure someone who handled it or were otherwise in contact with it, or who were close to it for a period of many weeks.

EN Revision Text: OFFSITE NOTIFICATION DUE TO EXCEEDING NPDES LIMIT
"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.

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.

EN Revision Text: AGREEMENT STATE REPORT - FIXED NUCLEAR GAUGE STUCK SHUTTER
The following information was received via E-mail:
"At 1400 CDT on July 16, 2021, the State was contacted by a representative of the licensee to report a radiation event that had been identified at 1530 CDT on July 15. The licensee was performing routine checks on a fixed gauge device. As part of the checks, they ensure that the shutter is able to be opened and closed. The individual servicing the gauge identified that the shutter was unable to be closed. All indicators are functioning as required to alert that the gauge is open. Staff who work in the area have been instructed that the device is unable to be closed, and to avoid working around the gauge even when it is not being utilized.
"The device is a Mahlo Model 11-200933, SN: 11-011988-ah-4868. It contains an Eckert and Ziegler Pm-147 source, SN: AH-4968. It has an assay date of 4/15/16, 1000 mCi. It currently contains approximately 250 mCi.
"No exposures of any individuals are suspected. The manufacturer was notified and is currently coordinating with the licensee to get a service engineer on site. The department will continue to follow-up with the licensee as arrangements are made."
