Gov. Robert Bentley issued an executive order Thursday declaring a state of emergency in Alabama over concerns about fuel shortages in the wake of a gasoline pipeline spill that released about 250,000 gallons of gasoline south of Birmingham and shut down a major pipeline connecting refineries in Houston with the rest of the country.

Georgia Gov. Nathan Deal issued a similar executive order for his state on Tuesday.

The pipeline operator, Colonial Pipeline, released the following information Thursday afternoon:

"Based on current projections and consultations with industry partners, parts of Georgia, Alabama, Tennessee, North Carolina and South Carolina will be the first markets to be impacted by any potential disruption in supply."

"Colonial has briefed officials in these states and will continue to provide timely information to the public so that they can plan accordingly."

The executive orders will allow fuel delivery truck drivers in each state to work longer shifts and exceed maximum hour limits established by the U.S. Department of Transportation in order to prevent gasoline outages.

The orders apply only to trucks that are transporting fuel to areas served by the pipeline.

In addition, some suppliers have begun shipping refined gasoline by water to New York from Houston while the pipeline is shut down.

The pipeline has been shut down since Friday and normally transports 1.3 million barrels per day of refined gasoline and other petroleum products from refineries in Houston to the south and eastern seaboard. The pipeline terminates at New York Harbor.

Colonial Pipeline spokesman Bill Berry said the pipeline delivered the products to tank farms like the one in Pelham, which sometimes have shorter "stublines" to pump gas to third party distributors.

Berry said he could not disclose how much refined gasoline from the pipeline normally went to Alabama service stations because it was proprietary information.

Colonial operates a second pipeline, Line 2, parallel to the damaged line that typically carries jet fuel, diesel or other non-gasoline products like home heating oil. According to Colonial's response information site, Line 2 is now transporting gasoline from Houston as far as western Alabama to alleviate supply concerns there.

U.S. EPA personnel at the site of the spill in Shelby County say local residents are not in danger, and the spilled gasoline appears to be contained at the site and unlikely to enter the nearby Cahaba River, which is home to a number of endangered species and other sensitive wildlife.

Bentley concluded his executive order by reminding all Alabama residents "it is unlawful for any person within the State of Alabama to impose unconscionable prices for the sale of any commodity during the period of a declared State of Emergency."
