A fire that destroyed 21 fuel storage tanks at a Caribbean Petroleum facility near San Juan, Puerto Rico, was extinguished on 25 October.
Vapours from an overflowing fuel tank caused the blast shortly after midnight on 23 October razing over half of the depot's 40 fuel storage tanks. More than 1,500 people were evacuated out of fears of contamination, but there were no reported fatalities.
Immediately before the blast, a tanker ship had released nearly 28,000 gallons of fuel into the tanks, and an undetermined amount spilled into a drainage ditch that is capable of handling a 10% overflow.
US President Barack Obama had declared the incident a national disaster and had made necessary federal resources available to the five Puerto Rico municipalities affected by the emergency.
The US Environmental Protection Agency (EPA) has begun to inspect the impact area, along with the Puerto Rico Police Department, in order to determine the agency's role in the investigation and clean-up of the zone.
Air and water quality continues to be monitored. Fears over a fuel shortage have been quickly quashed, as there are more than 47.29 million gallons of regular petrol, 16.56 million gallons of premium and 13.4 million gallons of diesel available.
The FBI has since said there is no evidence of sabotage. More than 240 investigators analysed the explosion and did not find evidence it was intentional.
