SECONDARY CONTAINMENT BOUNDARY DOOR FOUND AJAR
"On 4/27/2015 at 0850 [EDT], Secondary Containment (Unit 1 Reactor Building) Boundary Door-721 was found ajar. The door was closed by operators. A status walkdown was performed and no other doors were found in this condition.
"Although, Secondary Containment differential pressure was maintained throughout the time period that the door was not fully closed and latched. The door serves as a Secondary Containment boundary and is required to be closed for Secondary Containment Operability.
"This event is being reported under 10 CFR 50.72(b)(3)(v) and per the guidance of NUREG 1022 Rev 3 section 3.2.7 as a loss of a Safety Function. There is no redundant Susquehanna Secondary Containment System."
This door is in the railroad bay and was posted as a containment boundary door. Investigation into why this door was not closed and latched is continuing.
The licensee notified the NRC Resident Inspector.

OFFSITE NOTIFICATION TO LOCAL AGENCY
Notification was made to the San Diego Regional Water Quality Control Board, and a message was left for exceeding the daily maximum parts per million (ppm) of oil and grease in the North Industrial Area Yard Drain Sump. Sump pumps are currently in "OFF" and the site is investigating. The oil in the drain sump did not reach "reportable quantities" and did not require notifying other Federal Agencies.
