Union members are still off the job at the Marathon Petroleum refinery in Southwest Detroit. More than 250 members of Teamsters Local 283 have been on the picket line for seven weeks as they seek a fair contract.

With the strike ongoing, the Marathon refinery is using out-of-state workers to operate. Despite that, Michigan regulators just approved the facility to increase production. 

Gina Jones is a lab technician at the refinery. She says temp workers might not fully understand how to operate the plant.

“Yeah, you can bring scabs in,” says Jones, “but each refinery has its own little quirks. Unless you’ve been around for a while – and you know how to work with those quirks – somebody who comes in fresh, they’re not going to know.”

As a result, nearby residents and striking workers, like Jones, have safety concerns.

“(Refinery) startup is one of the most dangerous times,” Jones said. “Whenever you shut down or start up a refinery, that’s when accidents can happen.”

Workers are looking for stronger union protections, such as requiring new hires to join the Teamsters. They’re also asking for pay increases that outpace inflation.

However, union members say there have been no negotiations in weeks. That’s despite the presence of a federal mediator.

“They came to us saying, ‘we’ll give you a 2% increase,’” says Jones of prior negotiations. “And that’s laughable.”

Marathon Petroleum is set put out it’s third-quarter earnings in early November.

In the second quarter of this year, the oil giant made $1.52 billion.

After this story published, a Marathon Petroleum spokesperson wanted to reiterate:

• All employees in operations roles at the refinery have demonstrated competency specific to their assigned job tasks, including passing all required tests.
• The Marathon employees currently running the refinery and supporting the turnaround have a combined average of more than 15 years of experience each, which is more than the average experience of the employees currently on strike.

The Michigan Department of Environment, Great Lakes, and Energy (EGLE) has approved new air permits for Marathon Petroleum’s Detroit refinery after a public comment period earlier this year.

The permit changes will allow Marathon to operate the refinery — located at 1001 South Oakwood — at “full capacity,” and set new pollutant emission caps for the facility. Previously, the refinery was limited to producing an average of 140,000 barrels a day.

Andy Drury, an environmental engineer with EGLE, says the department will require Marathon to continue air quality monitoring through at least 2030.

“One of the bigger things is Marathon has been doing ambient air monitoring at their facility, and they have agreed based on the comments to continue for at least six more years,” Drury said.

Key updates to the permit include the removal of outdated regulatory references, an extension of the air monitoring program, and increasing the height of a refinery stack to 35 feet.

Jeff Tricoff, a relief operator at Marathon’s Detroit refinery and a member of  Teamsters Local 283, was among several residents who expressed concerns about increased capacity at the facility at a public hearing hosted by EGLE in May.

“As workers, we know that operating everything at 100% has to be done effectively and efficiently and done by experienced people,” Tricoff said at the meeting. “Right now we are in a labor dispute with our current contract having expired on Feb. 1, and Marathon is preparing to bring in temporary workers to take our position.”

Just last week, refinery workers represented by the union voted overwhelmingly to authorize a strike. The new permits were approved on Sept. 10.

Marathon also operates an asphalt terminal at 301 S. Fort St., and a light products terminal at 12700 Toronto St., both in Southwest Detroit.
