The Detroit refinery proudly supports Michigan Governor Whitmer’s Pollution Prevention Week by highlighting our commitment to reduce emissions and improve air quality across the state.
We’ve invested $350 million in environmental and safety improvements over the past decade to enable us to produce cleaner fuels and products with less environmental impact than ever before. As illustrated in the “Detroit Refinery Criteria Air Pollutant Emissions” chart, the Detroit refinery has operated at more than 40% below its yearly permitted emission levels for the past 15 years; and it has reduced its emissions by 80% over the past 20 years.
Other examples of improvements at the Detroit refinery include:
- As part of a consent decree, we partnered with the U.S. Environmental Protection Agency to implement several measures to lower emissions. The refinery installed a flare-gas recovery system that minimizes emissions by recovering gases and returning them to process equipment. The EPA considered the solution a model practice and shared Marathon’s advancements with refining companies nationwide, improving air quality at refineries across the country.
- Installed a state-of-the-art wastewater treatment plant in 2015 that allows for full treatment of industrial water before further processing at the Great Lakes Water Authority, and reduces industrial waste traveling through the local sewer system.
- Implemented a program that reuses our refinery discharge water onsite, reducing both our discharge and overall water consumption.
- Continue to help improve Michigan’s air quality by producing gasoline and diesel fuel that beats the strictest EPA standards for ultra-low sulfur fuels, resulting in lower vehicle emissions. The Detroit refinery produces approximately 25% of the transportation fuel used in Michigan, so the impact on reduced emissions and improved air quality across the state is considerable.
Marathon Petroleum’s Detroit refinery is one of 24 businesses engaged in heavy industry in this part of Southwest Detroit. And as a business leader in the region, we accept the responsibility to manage our impact on the environment, in every aspect. This commitment has driven our success in dramatically reducing emissions from our both our production processes and the use of our products.
We’re proud to call Southwest Detroit our home. We’ve been part of this community for 60 years, and we’re just getting started.
