| Title | Offsite Notification of a Spill of Acidic Water |
| Event Description | The licensee made an offsite notification to the Maryland Department of the Environment based on the release of approximately 705 gallons of very acidic demineralized water (Ph of 1) to a storm drain. The drain is connected to a system that leads to the Chesapeake Bay. The acidic water is coming from a non-isolable leak from the 11 Waste Neutralizing Tank. The leakage is onto a gravel base below the tank which is about 5 feet from the storm drain. The leak rate is at a rate of about 1 GPM. The licensee has set up a system to divert some of the leakage from the storm drain and capture it in waste barrels but some of the water is still being spilled onto the ground. The long term remediation of this problem is to neutralize the tank with a caustic solution and then discharge the tank.
The licensee has also notified Calvert County and the NRC Resident Inspector.
