The Oklahoma Environmental, Health and Safety Audit Privilege Act is now effective as of November 1, 2019, and available to manufacturers and industrial businesses  in Oklahoma that undertake voluntary environmental audits, such as those companies involved in aircraft manufacturing, chemicals, oil and gas processing, plastics, cement, food and meat processing, and paper products .  Oklahoma is the 30th state, by EPA’s count, to enact an audit program, providing privilege and enforcement benefits to parties that voluntarily undertake an environmental audit, disclose the findings and conduct corrective actions.
