EPA monetized both on-site and off-site damages. EPA estimated total average annual on-site damages of $265.8 million. The largest monetized average annual on-site damage was on-site property damage, which resulted in average annual damage of approximately $205.5 million. The next largest impact was on-site fatalities ($49.8 million) and injuries ($10.5 million).
EPA estimated total average annual offsite damages of $8.9 million. The largest monetized average annual offsite damage was:
- sheltering in place ($4.1 million),
- medical treatment ($1.5 million),
- property damage ($1.1 million),
- fatalities ($0.9 million),
- evacuations ($0.7 million), and
- hospitalizations ($0.7 million)
In total, EPA estimated monetized damages from RMP facility accidents of $275 million per year. However, the monetized impacts omit many important categories of accident impacts including
- lost productivity,
- the costs of emergency response,
- transaction costs,
- property value impacts in the surrounding community (that overlap with other benefit categories), and
- environmental impacts.
