| Title | Licensee-Identified Violation |
| Description | 10 CFR 20.1302(a) requires, in part, that the licensee make or cause to be made surveys of radioactive materials in effluents released to unrestricted and controlled areas to demonstrate compliance with the dose limits for individual members of the public in 10 CFR 20.1301. Upon discovery of abnormal effluent releases from the Storm Drain Stabilization Pond (SDSP) in May 2007 (i.e. seepage from the unlined pond to the surrounding marsh), which had been occurring for an indeterminate period of time, the licensee determined they had not evaluated all of the liquid effluent dose pathways to members of the public from SDSP releases. In addition, the licensee determined that the dose to the public resultant from gaseous effluent releases (i.e. evaporation of tritiated water) from the SDSP had not been evaluated. At the time of the June 2007 inspection, the licensee had performed a preliminary evaluation of offsite public dose from the marsh area. At the time of the March 2008 inspection, the licensee had completed an initial evaluation of the public dose resulting from evaporation of tritiated water from the SDSP. The preliminary dose assessments determined that both the seepage (tidal marsh) and the evaporation pathways from the SDSP contributed an incremental dose to the public comparable in magnitude to previously assessed liquid and gaseous effluent pathways. The preliminary dose assessments were sufficient to demonstrate compliance with the requirement to maintain doses to members of the public from radioactive effluents ALARA as specified in Appendix I to 10 CFR 50 and to demonstrate that the effluent concentration limits in Appendix B to 10 CFR 20 were not exceeded. The licensees dose assessments will be finalized and included in the 2007 Radioactive Effluent Release Report. This event is documented in the licensees CAP as NCRs 233865 and 233857. The violation was evaluated using the Public Radiation Safety Significance Determination Process and was determined to be of very low safety significance (Green) because this finding in the effluent release program was neither a failure to implement the effluent program nor an occurrence of public dose exceeding the 10 CFR 50 Appendix I criterion or 10 CFR 20.1301 limit |
