The Republican state of Indiana shows its support of businesses and contempt for the environment. Michael Hawthorne reports in the Chicago Tribune:

The massive BP oil refinery in Whiting, Ind., is planning to dump significantly more ammonia and industrial sludge into Lake Michigan, running counter to years of efforts to clean up the Great Lakes.

Indiana regulators exempted BP from state environmental laws to clear the way for a $3.8 billion expansion that will allow the company to refine heavier Canadian crude oil. They justified the move in part by noting the project will create 80 new jobs.

Under BP’s new state water permit, the refinery — already one of the largest polluters along the Great Lakes — can release 54 percent more ammonia and 35 percent more sludge into Lake Michigan each day. Ammonia promotes algae blooms that can kill fish, while sludge is full of concentrated heavy metals.

The refinery will still meet federal water pollution guidelines. But federal and state officials acknowledge this marks the first time in years that a company has been allowed to dump more toxic waste into Lake Michigan.

BP, which aggressively markets itself as an environmentally friendly corporation, is investing heavily in Canadian crude oil to reduce its reliance on sources in the Middle East. Extracting petroleum from the thick goop is a dirtier process than conventional methods. It also requires more energy that could significantly increase greenhouse gases linked to global warming.

Environmental groups and dozens of neighbors pleaded with BP to install more effective pollution controls at the nation’s fourth-largest refinery, which rises above the lakeshore about 3 miles southeast of the Illinois-Indiana border.

“We’re not necessarily opposed to this project,” said Lee Botts, founder of the Alliance for the Great Lakes. “But if they are investing all of these billions, they surely can afford to spend some more to protect the lake.”

State and federal regulators, though, agreed last month with the London-based company that there isn’t enough room at the 1,400-acre site to upgrade the refinery’s water treatment plant.

The company will now be allowed to dump an average of 1,584 pounds of ammonia and 4,925 pounds of sludge into Lake Michigan every day. The additional sludge is the maximum allowed under federal guidelines…
