Process Safety Initiatives Implemented in 2022:
Enhanced Incident Investigations – Performing
quality incident investigations has been a
priority for many years. This has resulted in a very
strong process that ensures quality corrective actions
to prevent a recurrence. In 2022, Valero issued a new
incident investigation policy that included a suite
of tools to improve the way we capture information,
evaluate human factors, engage with subject matter
experts and the workforce, and share lessons learned
throughout the Valero system.

Shared Learning – To leverage the benefits of
our enhanced incident investigation process,
Valero continues to introduce new and innovative ways
to effectively share incident investigation learnings
more broadly using various multimedia tools, including
webcasts and animated videos.
