Safety, health and environment

Safety is fundamental at the Billings Refinery, where we have a simple goal: “Nobody gets hurt.”

The refinery has a commitment to safe operations for our employees, contractors, neighbors and community. As part of the New Source Review (NSR) Consent Decree, the refinery has completed several large-scale, multimillion-dollar environmental projects that have significantly reduced emissions. Since 2002, SO2 emissions at the Billings Refinery have decreased by 90 percent.

In 2002, the refinery received certification on 110 acres of undeveloped wildlife area. The refinery was recertified by the international Wildlife Habitat Council in 2005, 2008, 2011 and 2014 for outstanding habitat management and environmental education.
