GARDEN CITY -- Gas prices continue to rise as damage from Hurricane Katrina has contributed to a shortage of fuel in Michigan.

The price of unleaded regular at a Marathon station in Garden City was at $3.92, but the owner told Local 4 that the station has been closed for three weeks. Motorists have been stopping to take pictures of the sign as evidence of rising prices across the metro Detroit area, Local 4 reported.

A price of $2.91 for regular unleaded at a station at Gratiot Avenue and Rochell in Detroit was beginning to look like a bargain compared to some other locations, the station reported.

At 12 Mile Road and Masonic in Roseville, prices have reached $3.29.

A BP station at 12 Mile and Southfield was at $3.05, while prices at a station across the street jumped to $3.44.

About 40 percent of Michigan's gasoline comes from the Gulf Coast, where Hurricane Katrina has caused shutdowns of oil platforms, refineries and pipelines. The impact of the storm drove energy prices sharply higher on Tuesday.

Plastic shopping bags covered some of the pumps at a BP station in Dearborn Heights.

The station was selling premium gasoline for $2.98, the price of their regular unleaded, which was empty.

Fouad El Jalal, the manager of the station, tried calling for a new shipment of gas, but supplies are apparently low, the station reported.

Gasoline distributors like Atlas Oil in Taylor say while crude oil is plentiful around the world, the gasoline that would normally be shipped to Michigan is not, the station reported. The refineries making much of the state's gas are underwater and won't get up and running for at least another week.

Gov. Jennifer Granholm said she's asked the Environmental Protection Agency to allow her to sell a more polluting brand of gasoline in metro Detroit, which is sold in other parts of the state and may help increase the supply. Granholm is also asking for drivers to help with the shortage problem.

"We think that if consumers act in a rational way, don't exacerbate the problem by rushing the gas stations or by topping off your gas when it's not necessary, that there may be a temporary spike," Granholm said.
