Improved Operational Risk
Management Programs – We
developed and implemented
new risk assessment standards
and tools designed to improve
the consistency and ef昀椀ciency
of existing programs. New
electronic systems were
introduced that leverage
technology to provide more
immediate operating data and
system information for analysis,
trending and corrective
actions.
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 2023, Valero
issued new tools and training
focused on the identi昀椀cation
of human and organizational
performance opportunities for
improvement.
Shared Learning – To leverage
the bene昀椀ts 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.
