La Pampilla refinery

The construction of the refinery was put out to tender in 1964 and inaugurated in 1967,^[2] built by Temach Co. In 1996, the refinery became part of Repsol^[3] for around 180 million dollars, as part of the privatisation process carried out by former president Alberto Fujimori.

In 2014, the modernisation of the refinery began, estimated at US$740 million.^[4] It was expected that modernization would reduce the oil's sulfur content to 50 ppm by 2016 as well as the improvement of other fuels by 2018.^[5]

On January 15, 2022, while crude oil was being unloaded at the refinery, an oil spill of an estimated 6,000 barrels occurred on the Mar de Grau. It significantly affected flora and fauna and was considered the largest ecological disaster to occur on the Peruvian coast.^{[citation needed]}

The refinery and its owner, Repsol, have been harshly criticised for the cleaning and decontamination work carried out after the spill,^[6][7] reflecting the lack of a contingency plan for possible disasters.^[8]

The government responded by stopping activities in terminal No. 2 of the refinery^[9] and imposing a fine of 33.4 million dollars.^[10]
