ENVIRONMENTAL, SOCIAL AND GOVERNANCE REPORT • 41 Safety is our foundation for success . Valero is dedicated to safety. We strive to make sure our employees and contractors go home safely and to meet our fence-line communities' expectations. A decrease in the number of employee and process safety events reduces unplanned shutdowns and increases the operational reliability of our plants. This, in turn, translates into a safer workplace with fewer environmental incidents and stronger community relations. We strive to improve safety and reliability performance by making it an integral part of our culture and offering year-round training for our employees and contractors . To bolster our safety performance, we conduct safety audits, quality assurance visits and comprehensive risk assessments at our facilities. 2021 set new records for safety performance. Our efforts to make continuous improvements resulted in 2021 being our best year ever for safety performance . Refinery employee annual total recordable incident rate (TRIR) was a record low of 0.21 incidents per 200,000 working hours, while the refinery Tier 1 process safety event rate was its lowest ever at 0.05 events per 200,000 working hours. In 2021, we spent approximately $1.8 billion in capital to grow and sustain our operations as part of our commitment to investments in safety, preventive equipment maintenance, environmental mitigation and reliability.
