On April 24, 2025, the EPA contacted the SSC to notify NOAA about a 50-gallon diesel spill on Blewett Pass in WA. The spill occurred several months ago (sometime between December 2024 and February 2025). EPA was just made aware of the spill. There does not appear to be an NRC notification associated with this release. The spill entered Tronsen Creek (which feeds into Peshastin Creek and ultimately the Wenatchee and Columbia Rivers). WAECY is planning on conducting a site visit next week. SSC notified NMFS. No further support has been requested.

USFWS notified the SSC on 4/22/2024 regarding the M/V Maunalei, en route to the Anchorage and Kodiak, AK. The vessel is leaking Environmentally Acceptable Lubricant (synthetic oil/ester oil) from the hub area around the pitch propeller. The EAL dissipates before reaching the surface. (Estimated to be 1 L per hour). QI reported to ADEC they plan to deploy boom containment around the vessel upon arrival in Anchorage (ETA 4/26/2025) and in Kodiak, AK as a precautionary measure. SSC forwarded the email to USCG Sector Western Alaska and US Arctic. No requests for support.

On April 31, 2025 an Apache Corporation Platform approximately 25 miles southeast of Grand Isle in West Delta released 20-50bbl of crude oil into the Gulf. NOAA provided initial trajectory.

On April 21, 2022, a Florida Marine Transportation Barge 3112 allided with a bridge in Melville, LA at mm30 of the Atchafalaya River along the left descending bank. The barge was carrying a total of 14k bbl (approx 600,000 gallons) of ethanol distributed between 4 tanks. One of the tanks is damaged and discharging ethanol into the river. The USCG requested NOAA support. Ethanol Fact Sheets were provided to USCG.

On April 18, 2025, USCG Sector New York notified the NOAA SSC that as a result of a fire at the Levchak Oil Company, located in North Arlington, NJ, an estimated 20,000 gallons of cooking oil was released into a marsh adjacent to the Hackensack River. SSC provided USCG with information about product spilled, response recommendations and potential environmental impacts.

On April 14, 2025, a NESDIS Marine Pollution Surveillance Report (MPSR) documented sheen adjacent to Texas Petroleum Investment Company (TPIC) Main Pass 81 B South Platform. Southern SeaPlane conducted an overflight at 2pm in this immediate area and reported sheen and provided low resolution photographs to TPIC. On April 15, USCG contacted TPIC after review of the MPSR. TPIC provided 2 of the low resolution photographs and reported that no sheen was present at the platform. USCG and NOAA SSC will continue to monitor reports in this area. **This report is not related to the TPIC Main Pass 81 Wellhead #36 Oil Spill report from last week.**

On April 14, 2025, USCG Sector Jacksonville notified the SSC that a 50 foot, steel hulled fishing vessel broke anchor and came ashore at Flagler Beach south of St Augustine, Florida yesterday. Vessel has 300 gallons of diesel aboard. No damage to the vessel or pollution has been reported at this time. Owner will attempt to refloat the vessel later today during high tide. Case pends.

On April 10, a NESDIS Marine Pollution Surveillance Report (MPSR) identified a potential oil spill east of the delta. On April 11, the U.S. Coast Guard's investigation revealed that a pin hole leak in a 4-inch flow line, leading to a Texas Petroleum Investment Company (TPIC) wellhead in Main Pass block JK North, resulted in an approximately 10-gallon crude oil spill into the Gulf. National Response Center Report #1428336 Source is secured and repairs underway. No recoverable oil identified. USFWS notified.

On April 10, 2025, a NESDIS Marine Pollution Surveillance Report (MPSR) identified a potential oil spill east of the delta. On 11 APR: USCG investigation revealed that a pin hole leak in a 4-inch flow line leading to Texas Petroleum Investment Company (TPIC) Wellhead 36 resulted in an approximately 20-gallon crude oil spill into the Gulf. Source is secured and repairs underway. No recoverable oil identified.

At approximately 0630 on 11APR2025 the F/V EILEEN RITA ran aground near Green Island outside of Boston Harbor. Diesel fuel is leaking from the vessel.

On April 2, 2025, the local NWS Weather Forecast Office staff contacted their NOAA SSC to relay a report from Contra Costa Fire Department of an ongoing spill being investigated in Carquinez Strait in Crockett, CA. A Cal OES report (No. 25-1666) was generated at 1719 hrs (local) describing “a large sheen forming in the waters of Carquinez Straights” ” and concurrent observations indicated a petroleum smell and a sheen, but no black oil. SSC contacted USCG, which had not yet heard of the incident, but would investigate. A USCG helicopter overflight observed bright white silver streaks/streamers in the waters of Carquinez Strait and local news later reported an unknown odor being investigated by local FD.

On April 1, 2025, a TPIC facility was reportedly spraying condensate and oil in the vicinity of Southwest Pass. The resulting sheen was spotted as far as 2 miles south in Cockler Bay. The reported quantity released is 5bbl. TPIC OSRO en route. USCG will be onsite 2 APR and requested SSC support.

USCG contacted the SSC regarding a discharge reported at the King Salmon oil & gas production platform in Cook Inlet. The discharge was originally reported as five gallons of a mixture of produced water and crude oil. but the USCG followed up with the SSC to report that the product discharged was not crude oil but a 'corrosion inhibitor.'

On March 29, 2025, the NMFS PRD Oil Spill team contacted the SSC regarding a discharge reported by Alaska Wildlife Troopers between Cape Pankof and Sand Point, Alaska. The vessel released the diesel fuel through its tank vents while it was moving -- over approximately 100 miles. There is no recoverable product.

On March 28, 2025, the NOAA NESDIS satellite surveillance program reported a mystery sheen in Main Pass 24 in the Gulf of America. The reported sheen was as long as 11nm. On 29 MAR, a USCG overflight confirmed the presence of oil on water. Oil producers in the vicinity of the sheen did not report any spills or malfunctioning equipment.

On March 27, 2025, the USCG MSD Sitka contacted the SSC regarding a unknown blue product found in Eliason Harbor, Sitka, AK. The product was a neon-blue with a strong diesel order, but more viscous than diesel. USCG requested assistance with identifying the product.

NMFS Protected Resources Division contacted the SSC regarding a NRC report for some heavy equipment that broke through the ice on the Susitna River on March 25, 2025. The RP reported a potential discharge of diesel fuel and lubricants - but no sheen was reported. The river is important habitat for the endangered Cook Inlet population of Beluga Whale.
