1153113 02/09/2026 Surface Water Approximately 20-gallons of marine diesel spilled onto the main deck of the USNS Sojourner Truth from a pressurized 4" line. A small portion of the fuel sprayed over the port side of the vessel and reached the Bay and pier below. Spilled fuel also discharged to the Bay through a nearby deck drain. Environmental Engineering reported the incident to NRC (#1454476), OES (26-0651), and left a voicemail to the RWQCB (Ella Knight). Violation N eSMR National Steel & Shipbuilding Co (NASSCO) 459091 R9-2023-0012 N
1150652 10/03/2025 Surface Water On October 3, 2025, at approximately 1615 hours, NASSCO Security received a report of 55 gallons of oil spilled on the flight deck of the USNS Sojourner Truth (TAO-6). NASSCO's Fire Department (NFD) responded to the incident and found approximately 50 gallons of hydraulic oil on the flight deck of the TAO-6, which had spilled due to an overfilled 55-gallon drum. The source of the spill was secured, and NFD began containing the spill using rags and absorbent pads. Violation N eSMR National Steel & Shipbuilding Co (NASSCO) 459091 R9-2023-0012 N
1150651 11/21/2025 Surface Water On November 21, 2025, at approximately 1130 hours, an estimated 500 gallons of stormwater from the Pier 12 Storm Water Diversion System (SWDS) discharged into San Diego Bay. The pier coordinator alerted NASSCO Maintenance and Environmental Engineering about a pipe that had disconnected from a pier scupper. Maintenance teams promptly responded, secured the pipe, and stopped the discharge. Environmental Engineering personnel arrived on site to find Maintenance actively working on the pipe and pumping the collected stormwater to the Waste Water Treatment Facility (WWTF). Due to safety concerns regarding the pipe's location on the waterside of the pier wall, Environmental Engineering was unable to collect a sample. However, visual observations revealed no evidence of suspended or floating materials, oil or grease, discoloration, turbidity, odors, trash, debris, or any other pollutants.

1148439 08/11/2025 Surface Water On August 11, 2025 at 0913 hrs, NASSCO Security received a report of a sheen in San Diego Bay adjacent to Berth 6 of approximately 800' x 100'. Security notified NASSCO Fire Department (NFD) and NASSCO Environmental Engineering (EE) to respond to the incident. At the time of the incident, two NASSCO departments were operating vessel systems that had the potential to discharge fuel. EE made regulatory notifications to the Office of Emergency Services (#25-3980), National Response Center (#143-9509), and Regional Water Quality Control Board (voicemail). An oil boom was around the vessel that contained the sheen and NASSCO Waterfront Services (NWF) placed a secondary boom around the sheen to prevent migration. NFD, EE, and WFS conducted an investigation to identify a source of the discharge. NFD nor EE identify any source or evidence of a spill onboard the vessel, NWF used a skiff and diver but did not identify a source within the water or under the vessel. NASSCO continued to monitor the incident, the sheen was not recoverable and dissipated over time. Violation N eSMR National Steel & Shipbuilding Co (NASSCO) 459091 R9-2023-0012 N
