(Whiting, IN) - The area's largest oil refinery has been hit with a hefty fine.  BP has settled in U.S. District Court for violating a previous agreement to clean up its Whiting, Indiana facility. 

Activists say the company has failed to reduce and monitor dangerous emissions.  BP agreed to a penalty of over $512,450 and will test for pollutants at least every 6 months while properly maintaining pollution control equipment. 

The refinery, which covers 1400 acres along Lake Michigan in Northwest Indiana, processes about 440,000 barrels of crude oil a day.
