Guaracara River Clean-up Completed

On Christmas Eve, Petrotrin completed the clean-up of oily water that escaped into the
Guaracara River earlier this week.

Due to an upset condition on one of the process units in the Pointe-a-Pierre refinery on Sunday
2014 December 21, 15 barrels of oil were discharged from the Desalter Unit. This was initially
retained within the catchment facilities however, on Monday about two (2) barrels spilled out
into the Guaracara River. Changing tides caused some patches of oil to move resulting in some
smearing along the river bank.

Upon discovery of the leak, Petrotrin employees have been in the community conducting
continuous monitoring for volatile organic compounds (VOC’s) and other emissions. These tests
have returned results of zero or well below discomfort levels.

Mindful of any possible discomfort to our Marabella community, our team worked industriously
to complete the clean-up exercise. As of yesterday, the leaked oil has been recovered however
general debris continues to litter the surface of the river and our team is monitoring the area to
treat with any residual cleaning required.

Petrotrin continues to implement a number of preventive strategies including new designs and
improved maintenance that require the collaboration of all stakeholders as we treat with our aged
Asset Integrity issues.

The support and understanding of our stakeholders is appreciated, as we work towards ensuring
the sustainability and viability of Petrotrin for the thousands who depend on us.
