Oil giant BP PLC could face more than $384,000 in fines over workplace safety violations at its refinery along Lake Michigan even as the company says it is making "solid progress" to correct those problems, the Associated Press reports. Scott Dean, a BP spokesman in Warrenville, Ill., said BP has so far fixed more than half of the 14 violations and is working to address the remaining ones at its Whiting refinery. Inspectors with the Indiana Occupational Safety and Health Administration cited BP Nov. 15 for eight "serious" violations, including failing to test equipment such as fire hydrants at the Whiting refinery based on inspections this year. BP also was cited five times for "knowing" safety violations, which the state deems more serious, for violations such as failing to correct problems with piping and relief-valve systems at the plant. Tim Grogg, special assistant commissioner of IOSHA, said agency inspectors visited BP''s Whiting plant in April 2005 after learning of the explosion at a BP refinery in Texas City, Texas, that killed 15 people and wounded 170 others.
