Pollution Is Called a Byproduct of a ‘Clean’ Fuel

After residents of the Riverbend Farms subdivision noticed that an oily, fetid substance had begun fouling the Black Warrior River, which runs through their backyards, Mark Storey, a retired petroleum plant worker, hopped into his boat to follow it upstream to its source.
Oil and grease from a biodiesel plant had been released.
It turned out to be an old chemical factory that had been converted into Alabama’s first biodiesel plant, a refinery that intended to turn soybean oil into earth-friendly fuel.
“I’m all for the plant,” Mr. Storey said. “But I was really amazed that a plant like that would produce anything that could get into the river without taking the necessary precautions.”
But the oily sheen on the water returned again and again, and a laboratory analysis of a sample taken in March 2007 revealed that the ribbon of oil and grease being released by the plant — it resembled Italian salad dressing — was 450 times higher than permit levels typically allow, and that it had drifted at least two miles downstream.
