Oct. 23 (Bloomberg) -- Puerto Rico has enough fuel to supply the island for almost a month after explosions and fire at a refinery and tank farm near San Juan in Bayamon.

The power authority has fuel to supply the island for about 24 days after 14 of the 40 tanks at Caribbean Petroleum Corp.’s farm were on fire today, Governor Luis Fortuno said in comments in a PR Newswire statement. The Federal Bureau of Investigation, U.S. Environmental Protection Agency, U.S. Coast Guard and others are coordinating efforts, Fortuno said.

“We will coordinate with wholesalers to ensure adequate fuel is supplied to all citizens,” he said. “There is no problem in terms of supply.”

A pair of explosions rocked the Bayamon facility at about 12:30 a.m. local time. Bayamon can process 48,000 barrels of crude oil a day, according to the company Web site.

The sour-crude refinery isn’t operating, according to undated information on the Web site. The facility also houses a tank farm and oil-product import terminal.

Calls to the company seeking comment went unanswered.

Diesel, gasoline, No. 6 heavy fuel oil and jet fuel are all stored at the tank farm, Ricardo Castrodad, a spokesman for the U.S. Coast Guard, said in a telephone interview. Puerto Rican authorities have requested assistance from hazardous materials specialists in the U.S., he said.

Caribbean Petroleum markets the Gulf brand on the island.

Safety Zone Approval

Vessels must receive special approval to travel in a mile- long safety zone established by local authorities from the Punta Catano to the Puerto Nuevo Intership facility, Castrodad said.

More than 300 residents have been evacuated from nearby homes, said Ana Santos, a spokeswoman for the state emergency management agency. More than 100 people are working to extinguish the fire, she said.

There is concern of spillage from the facility, Fortuno said in the CNN broadcast. The U.S. Environmental Protection Agency has yet to find any fuel that has spilled, he said.

The U.S. Chemical Safety & Hazard Investigation Board is sending a six-person team to investigate the explosion, said Daniel Horowitz, a spokesman. The board is an independent U.S. federal agency that investigates industrial chemical accidents. The cause of the explosion remains unknown.

“We don’t have a lot of information at this time,” Horowitz said in a telephone interview. “We’re coordinating with the other agencies involved.”
