Since 1997, mainly as a result of mergers and acquisitions, six companies have exceeded the legal limit of 246,080 acres in lease holdings on public lands in states other than Alaska. But the Bureau of Land Management (news - web sites), in charge of enforcing the 1920 law, has chosen to extend compliance deadlines for years.
In fact, an Associated Press computer analysis found the Interior Department agency permitted companies it knew were in violation of the law in Wyoming to continue to acquire thousands of acres of new oil and gas leases in that state. The bureau has given the companies additional years to comply.
"They should not be purchasing leases," said Tom Lonnie, the bureau's assistant director for minerals, realty and resource protection. Before acquiring a lease, a company must certify that its holdings do not exceed the legal limit.

The lax enforcement coincides with the Bush administration's push to open new public lands for oil and gas development. In March, bureau records showed 40 million acres of federal lands were under lease in the continental United States. That is 5.3 million more acres than when President Bush (news - web sites) took office.
