Federal safety regulators, state oil and gas authorities, and the energy industry need to close regulatory gaps that contributed to the worst oil drilling accident in nearly a decade, a federal agency said in an unprecedented report.

One of Alaska's biggest oil producers—BP—has announced it is selling all of its Alaska operations to Hilcorp, a privately-owned company with a troubled safety and environmental track-record.

Under pressure from worker safety advocates, the U.S. Chemical Safety Board (CSB) has decided to return to a policy of including the names of deceased workers in its investigative reports. The CSB, an independent federal agency charged with investigating industrial chemical incidents, has included names of fatally injured workers in its reports since 2014. The agency changed its policy in June with the release of two reports on fatal incidents.

A fatal fall was among the OSHA enforcement cases finalized over the past few days – violations that show a persistent failure among some construction industry employers to address fall hazards.
