| The U.S. EPA estimates that approximately 65,450 releases of petroleum or hazardous substances from federally regulated underground storage tanks (USTs) had not yet reached the "cleanup completed" milestone as of September 2018. The Association of State and Territorial Solid Waste Management Officials (ASTSWMO) estimates that in 2017, alone, state cleanup funds collectively spent approximately $1.113 billion in cleaning up UST releases. Use of green remediation best management practices (BMPs) can help minimize the environmental footprint of cleanup activities at UST-contaminated sites and improve overall outcomes of the corrective actions. In accordance with the EPA Principles for Greener Cleanups, BMPs outlined in the updated "Green Remediation Best Management Practices: Sites with Leaking Underground Storage Tanks" fact sheet are intended to complement federal requirements for corrective actions at UST-contaminated sites and may enhance state-administered UST program requirements. |
