BP fined $5.2 million for tribal lands inaccuracies

NEW YORK (CNN) -- BP America Inc. has been fined nearly $5.2 million for submitting "false, inaccurate and misleading" reports on energy production on Southern Ute Indian tribal lands in southwestern Colorado, the Department of Interior said Wednesday.

The civil penalty was assessed by the department's Bureau of Ocean Energy Management, Regulation and Enforcement, and is unrelated to the oil disaster in the Gulf of Mexico.

Southern Ute tribal auditors and the management bureau found that BP reported "incorrect royalty rates and prices for royalty purposes," and incorrectly reported well production on leases, the Interior Department said in a news release.

Tribal auditors initially discovered the errors during an audit conducted as part of a cooperative agreement with the bureau's Minerals Revenue Management Program, and the tribe brought them to BP's attention in August 2007, the department said.

After receiving audit letters and an order, BP (BP) agreed with auditors' concerns and "repeatedly promised to correct the problems, which they attributed to errors in their automated files," the department said.

But when federal officials and tribal auditors examined later production reports, the same errors were found, according to the Ocean Energy Management bureau's director, Michael Bromwich, "leading us to conclude that BP's continued submission of erroneous reports was knowing or willful."

BP America did not immediately return a call seeking comment.

"It is simply unacceptable for companies to repeatedly misreport production, particularly when it interferes with the auditing process," Bromwich said in the news release. "We are committed to collecting every dollar due from energy production that occurs on federal and American Indian lands, and accurate reporting is crucial to that effort."

The company may challenge the penalty through a Department of Interior hearing, the department said.
