On September 5, 2024, Southern California Edison reported, as a proactive measure, detectable levels of tritium in onsite groundwater wells to offsite government agencies. The tritium levels do not exceed reporting thresholds in the [Nuclear Energy Institute's] NEI 07-07 communication protocol, the offsite dose calculation manual (ODCM), nor the NRC regulations in 10 CFR Part 20. Offsite ocean water samples have not identified the presence of tritium above detectable levels. An investigation is currently ongoing to determine the source of tritium and determine mitigative actions, if any.
