Allegheny County residents are no longer required to fill their cars with a special blend of gasoline in the summer, the Environmental Protection Agency announced on Friday.

The rule was first introduced in 1995 in order to reduce the formation of ground-level ozone, a pollutant that has been linked to negative health outcomes such as asthma and chronic obstructive pulmonary disorder.

A damaged pipeline has prompted the Environmental Protection Agency to temporarily waive a requirement for a special, cleaner blend of gasoline in Allegheny County during summer months.

Labor Day weekend marks the end of the summer driving season, and soon, gasoline prices are expected to drop after spending most of the summer above $3 per gallon.

“Across the country, we switch over to winter blend gasoline, demand drops off, and you start seeing some relief at the pump,” said Jim Garrity, a spokesperson for AAA East-Central, which serves Pennsylvania, Ohio, West Virginia, New York and Kentucky.

The devastation from Tropical Storm Harvey along the Gulf Coast is starting to have a ripple effect on gasoline prices across the country.

The storm has taken about 14 percent the nation’s refining capacity offline. The national average price of gasoline has started to rise, as major refineries in the Houston area have shut down.

Patrick DeHaan, senior petroleum analyst with the online price-tracking firm GasBuddy, said Pennsylvania’s average of $2.55 per gallon will probably go up by about 10 to 15 cents.

More than 112,000 vehicles run on compressed natural gas (CNG) in the United States, the majority of which are commercial fleets, according to the Department of Energy, and those motorists now have one more place to fill up in Pennsylvania.

Pennsylvania Turnpike Commission officials Thursday unveiled three CNG fueling stations at the New Stanton Plaza in Westmoreland County. It is the first of the turnpike’s 17 plazas to offer the alternative fuel and is only accessible for westbound travelers.
