On August 22, 2023, NASSCO Security was notified of a spill to San Diego Bay from the USNS Earl Warren (T-AO 3) at Berth 2. Approximately 1 gallon of oily storm water overflowed into the Bay from the flight deck TAO-3 mid ship. Due to the storm prediction for Hurricane Hillary, the vessel was not accessible causing storm water to overflow from the vessel deck. The incident resulted in a visible sheen approximately 20 x 40 feet in size. |
NASSCO employees immediately secured the source and pumped remaining storm water from the deck once vessel access was restored. Water Front Services (WFS) contained the spill within an oil boom. NASSCO followed all best management practices, however, the spill was not recoverable.
NASSCO notified the following agencies: National Response Center (NRC #1376900), Office of Emergency Services (OES #23-5362), U.S. Coast Guard, and the Regional Water Quality Control Board (RWQCB) (voicemail & notification letter). |

On March 9, 2021 at approx. 1920 hrs., NASSCO Security was notified of a hydraulic oil spill to San Diego Bay from a Terex RT Crane located at the head of NASSCO¿s Pier 12. The crane at the pier accidentally rolled on its side causing ~0.8 gallons of oil to spill onto the deck of the pier from a hydraulic hose that ruptured during the crane incident*
To safely recover the crane, NASSCO personnel disconnected a hydraulic hose in order to relieve the hydraulic oil pressure to the crane¿s boom cylinder, it was during this time at approx. 20:30 hrs,. that ~7-8 gallons of hydraulic oil was released onto the pier deck and ~1 gallon released to the San Diego Bay. NASSCO Fire, Environmental, and General Services responded and immediately started cleanup activities on the pier; however, in-water oil recovery operations could not be initiated due to low lighting. On March 10, 2021 during the follow investigation, a mixture oil and rain water was identified on the pier, a thin film oil sheen covering an area ~75ft x 120ft was also identified on the surface of the water in the San Diego Bay under and around the head of NASSCO¿s Pier 12. |
The affected area on the pier was immediately isolated to prevent traffic, NASSCO¿s General Services was dispatched to vacuum the oil/rain water mixture from the pier. US Ecology (NASSCO¿s oil spill response contractor) was dispatched to evaluate the oil on the surface of the water for recovery determination. US Ecology tested the absorbency of the oil and due to its weathering it was determined the oil could not be recovered. |

On January 12, 2021, an unknown amount of back flow of water from the launch washed onto F-Lane (between F-12 and F-14) and drained back into the Bay possibly taking NASSCO containments (industrial activity dust and particulates) with it into the bay. A light gray dust sheen was observed on surface waters, however, the dust could not be recovered as it dissipated quickly and due to the ongoing launch evolution activities. NASSCO Environmental, Facilities and General Services immediately dispatched the pump truck and began pumping the excess flood water at the F-Lane into the pump truck holding tank to prevent further discharge.
The incident is a prohibited discharge under NASSCO's NPDES permit. However, the discharge did not exceed a Reportable Quantity (RQ) and did not endanger health or the environment.
The spill was a result of the back flow from the T-AO 1 launch at WAYS 3. The flood water backwash extended beyond the expected WAYS 3 flooding areas extending to the F-Lane laydown areas that were not cleaned which resulted dust sheen. All the areas beyond WAYS 3 (adjacent laydown areas) that had the potential to flood and backwash could not be identified earlier as this was a new hull class (new ship type).
|
Based on the results of the T-AO 1 launch, a BMP plan will be developed to address the adjacent laydown areas to prevent a discharge from further launches of this class of vessel. |

December 2, 2020 at 0816 hrs. NASSCO Security was notified of an abrasive blast media discharge to the San Diego Bay from a subcontractor¿s (IMIA) abrasive blasting operation at Berth 4.
IMIA failed to install screens on their vacuum lines prior to using the vacuums to remove spent blast media from their work area. This caused trash and debris to be vacuumed into the vacuum bottle and partially obstructing the valve. IMIA employees failed to secure the valve while attempting to remove the obstruction allowing spent blast media to spill into and overflowing the secondary containment onto the pier and into San Diego Bay causing approximately a 100 ft. x 180 ft. surface dust layer. IMIA employees cleaned up the spent blast media from the pier, however; the spent blast media in the Bay could not be recovered. |
A NASSCO Corrective Action Request was issued to IMIA to prevent reoccurrence, IMIA is tasked to ensure screens are installed on their vacuum lines and instructed to cease blasting operations when faulty equipment is identified. IMIA has reviewed the incident and conducted training with all its blasting employees. |
