The state of Michigan has hit a roadblock in its efforts to cut down on air pollution in Wayne County.

U.S. Steel is suing the state over a rule that requires the company to submit a plan for meeting sulfur dioxide standards at its Great Lakes Works plant in Ecorse.

Michigan has been trying get the Pittsburgh-based company and several others in the Detroit-area to scale back emissions since 2010, when a federal review found that levels were above standards.

Detroit’s Marathon refinery will have to cut emissions, under new permits issued this week by the Michigan Department of Environmental Quality.

Marathon needs to meet new federal requirements for low-sulfur gasoline.

Because it needed to remove that sulfur, Marathon initially asked to increase its sulfur dioxide emissions, in a heavily-industrial area already considered the state’s most polluted ZIP code.

But after a fierce public backlash, Marathon and the Michigan Department of Environmental Quality found ways for the company to actually reduce those emissions.

Michigan’s US Senators want the Environmental Protection Agency to step in if the state doesn’t act on a plan to curb Wayne County air pollution soon.

In a letter to EPA head Gina McCarthy Friday, Debbie Stabenow and Gary Peters urged “swift completion” of that plan.

In 2013, part the county was found to be in “non-attainment” with new National Ambient Air Quality Standards for sulfur dioxide emissions.

The Michigan Department of Environmental Quality was supposed to submit a plan to fix that to the EPA in April 2015. But to date, MDEQ still hasn’t done that.

The Michigan Department of Environmental Quality is moving forward on a new rule to cut air pollution in part of Wayne County.

The rule will limit sulfur dioxide emissions from two US Steel facilities. They’re in southwest Detroit and two downriver suburbs deemed in “non-attainment” of National Ambient Air Quality Standards (NAAQS).

Barb Rosenbaum is with the Michigan Department of Environmental Quality’s Air Quality division.

She says the agency is still working on a larger sulfur dioxide attainment plan for that area, after getting feedback on an initial draft.

The Michigan Department of Environmental Quality has a plan to curb sulfur dioxide pollution in Wayne County, and it has plenty of critics.

In 2013, an area of Wayne County that includes part of Detroit and some downriver communities failed to meet new federal ambient air quality standards for sulfur dioxide.
