ASTSWMO’s Emerging Fuels Task Force created the Corrosion Observations Tool for the purpose of submitting information on UST system corrosion observed during inspections and removals in the field. It is well known that some new fuel formulations are associated with accelerated corrosion, clogged filters, and other side effects; however, we do not have a complete understanding of how widespread these issues are, nor do we know if these issues are leading to increases in releases from UST systems. We encourage UST regulators, inspectors, contractors, and owners to use the Corrosion Observations Tool to report incidences of corrosion. Our goal is that assembling all this data will help identify trends, and especially we hope this toolkit will help identify potential problems before they become widespread.
