A federal judge in New Orleans on Tuesday blocked a six-month moratorium on new deep-water drilling projects imposed in response to the massive Gulf oil spill.
The White House said the administration would appeal. It had halted approval of any new permits for deep-water drilling and suspended drilling at 33 exploratory wells in the Gulf.
Several companies that ferry people and supplies and provide other services to offshore drilling rigs asked U.S. District Judge Martin Feldman in New Orleans to overturn the moratorium, arguing it was arbitrarily imposed.
Feldman agreed, saying in his ruling that the Interior Department failed to provide adequate reasoning for the moratorium. He said it seemed to assume that because one rig failed, all companies and rigs doing deep-water drilling pose an imminent danger.
"An invalid agency decision to suspend drilling of wells in depths of over 500 feet simply cannot justify the immeasurable effect on the plaintiffs, the local economy, the Gulf region and the critical present-day aspect of the availability of domestic energy in this country," Feldman wrote.
The moratorium was imposed after the April 20 explosion on the Deepwater Horizon drilling rig that killed 11 workers and blew out the well that has spewed millions of gallons of oil into the Gulf.
The Interior Department said it imposed the moratorium so it could study the risks of deep-water drilling. But the lawsuit filed by Hornbeck Offshore Services of Covington, La., claimed there was no proof the other operations posed a threat.
The moratorium was declared May 6 and originally was to last only through the month. President Barack Obama announced May 27 that he was extending it for six months.
In Louisiana, Gov. Bobby Jindal and corporate leaders have opposed the moratorium, saying it will result in drilling rigs leaving the Gulf of Mexico for lucrative business in foreign waters. They say the loss of business will cost the area thousands of lucrative jobs, most paying more than $50,000 a year. The state's other major economic sector, tourism, is a largely low-wage industry.
In its response to the lawsuit, the Interior Department said the moratorium is necessary as attempts to stop the leak and clean the Gulf continue and new safety standards are developed.
"A second deep-water blowout could overwhelm the efforts to respond to the current disaster," the Interior Department said.
The government also challenged contentions the moratorium will lead to long-term economic harm. Although 33 deep-water drilling sites were affected, there are still 3,600 oil and natural gas production platforms in the Gulf, the government said.
