Abstract
On August 20, 1997, Illinois submitted a variance to allow Marathon Oil to emit particulate matter in increased quantities from June 14, 1996, to September 5, 1996, to allow the company to defer repairs of its control equipment until a scheduled system shutdown. The submittal included modeling to indicate that the temporary emissions increase would not be expected to cause a violation of air quality standards. USEPA is approving this variance because air quality standards continue to be protected.
