Decommissioning and Removing Petroleum Storage Tanks: Understanding State and Federal Requirements After Replacement or Disuse

Navigating petroleum storage tank decommissioning regulations for aboveground storage tanks (AST) and underground storage tanks (UST) requires attention to distinct processes.

Both AST and UST decommissioning necessitate residual fuel removal and thorough tank cleaning. However, UST decommissioning typically involves mandatory physical removal of the tank from the ground, rendering it unusable, and comprehensive environmental sampling and reporting to ensure no leaks occurred. Although UST in-place waivers are possible, cost savings are not a justification. AST decommissioning offers more flexibility, allowing the tank to remain on-site if clearly labeled as “not in service.”
