| Title | Offsite Notification - Sodium Hypochlorite Spill and Release |
| Event Description | On 01/24/2011, at 0900 EST, Peach Bottom Atomic Power Station had a spill and release of Sodium Hypochlorite from our water treatment plant's Sodium Hypochlorite tank. The quantity [rate] of release has been estimated at approximately 1 gpm to the surrounding soil area. The leak was into a moat surrounding the tank but it appears it has subsequently leaked from the moat. The leak was identified on 01/24/11 and was quantified as reportable at approximately 0900 EST. The leak is currently in progress with actions being taken to mitigate and control leakage to the area storm drain. This is a release of CERCLA (Comprehensive Environmental Response Compensation and Liability Act) reportable quantity of substance.
The release impacted or potentially impacted the Susquehanna River due to release through a storm drain and additional impact to the surrounding soil. Additional measures being taken include installing additional barriers to release. Lewis Environmental Hazard Mat team has been contacted and is responding to the site. In addition a truck has been dispatched to the site to pump out the moat. This report is being submitted pursuant to 10CFR 50.72(b)(2)(xi) as a result of a notification of other government agencies. The licensee has notified the NRC Resident Inspector, and state and local government agencies.
As of 2200 [EST] last night, the leaking tank and moat area have been drained, and all standing liquid has been removed. Hourly water samples were collected from the discharge canal and tested. These samples confirmed that no release in excess of the station's NPDES [National Pollutant Discharge Elimination System] permit occurred. Notified the R1DO (Newport). |
