On July 25, 2024, the Philippine-flagged industrial fuel tanker MT Terranova[a] (IMO number: 9092666) capsized and sank in Manila Bay, off the east coast of Lamao Point, Limay, Bataan, causing an ongoing oil spill.

The Philippines was struck by heavy rainfall and strong winds caused by the southwest monsoon enhanced by Typhoon Gaemi (locally called Carina) in late July 2024.

[3] On July 27, the motor tanker MTKR Jason Bradley, carrying 5,500 liters of diesel fuel (although it was initially believed that this had already been emptied) sank in 9-meter-deep (30 ft) waters 600 yards off the coast of Barangay Cabcaben in the neighboring municipality of Mariveles.

PCG spokesperson Armando Balilo stated that the oil spill had a significant risk of impacting the livelihoods of local fishermen by damaging the marine environment of Manila Bay.

[21][22] On July 30, Bataan Governor Joet Garcia imposed a no-fishing zone on Limay,[23] later adding that about 14,000 people working in the province's fishing industry would be affected by the oil spill.

[25][26] On July 31, a state of calamity was declared in the municipalities of Kawit, Noveleta, Rosario, Tanza, Naic, Maragondon, and Ternate and the city of Bacoor in Cavite by Governor Jonvic Remulla.

[27] A ban on catching shellfish was also declared in Cavite, while the Bureau of Fisheries and Aquatic Resources (BFAR) said that fish samples taken from parts of the province before the appearance of oil slicks had already tested positive for petrochemicals.

[34] Environment secretary Toni Yulo-Loyzaga deployed the survey vessel BRP Hydrographer Presbitero to conduct ecosystems mapping of areas affected by the oil spill.

[44] The Department of Environment and Natural Resources (DENR) estimated that around 4,700 hectares of critical ecosystems and 44 sites linked to the Asian Waterbird Census could be affected within a 30-kilometer radius of where the Terranova sank.

[46] On August 1, the PCG also announced the postponement of oil siphoning from the Terranova for about two weeks, citing the need to replace the initial capping bags on the valves of the vessel with metal ones to prevent more discharges during the actual removal.

[57] On September 12, the contracted salvor, Harbor Star, reported they recovered 1,415,954 liters of oil and an additional 17,725 kilograms of solid oily waste as part of the variance volume representing a recovery rate of 97.43%.

The remaining 37,867 liters, accounting for 2.57% of the total oil cargo, were lost due to various factors such as biodegradation, dissipation, absorption by sorbent booms, and unpumpable sludge left in the tanks.

[62] Records from the Bureau of Customs also showed that the Jason Bradley was the subject of a seizure and detention warrant in 2022 for failing fuel marking tests and inability to provide evidence of payment of duties and taxes.
