| Title | Sodium Hypochlorite in Excess of State Permit Limits |
| Event Description | At 1420 EDT on 7/1/17, Fermi 2 determined that the site was in violation of its National Pollutant Discharge Elimination System (NPDES) permit due to chemical addition pumps (for the cooling tower reservoir) being out of service for approximately seventeen hours. This resulted in sodium hypochlorite concentrations exceeding state limits. As of 0855 EDT [on] 7/1/17, the levels of sodium hypochlorite were restored to less than measureable values.
Reports will be made to the Michigan Department of Environmental Quality (MDEQ) and other local agencies. Since these reports are in the process of being made, this is considered a news release or notification to other government agencies, therefore this event is reportable under 10 CFR 50.72(b)(2)(xi). The NRC Resident Inspector has been notified. The licensee also notified Monroe County. |
