HOUSTON (AP) - The Environmental Protection Agency says the Texas City refinery where 15 people died in an explosion last year is also the nation's worst polluting plant.
The plant is operated by energy giant BP.
According to numbers obtained by the Houston Chronicle, the plant produced three times as much toxic pollution in 2004 as it did the previous year.
The dramatic increase has raised questions about whether BP under-reported its pollution in the past.
But BP says the figures from 2004 -- some 10 (M) million pounds of pollution -- may be incorrect because of a recent change in how the plant calculates emissions.
More federal fines could be levied against BP if the company finds it was under-reporting pollution.
After the deadly explosion last March, BP was fined more than $21 million for safety and health violations.
