What must be done with abandoned underground tanks according to regulations in Maine?

In Maine, regulations stipulate that abandoned underground tanks must be properly closed and removed to ensure public safety and environmental protection. This is crucial because improper closure can lead to leaks and contamination of soil and groundwater, which poses significant health risks and ecological damage.

The process typically involves either emptying the tank, cleaning it thoroughly, and then filling it with an inert material or removing it entirely from the site. This approach aligns with best practices in waste management and environmental stewardship, aiming to eliminate potential hazards associated with unused or neglected tanks.

Leaving tanks in place or allowing them to be reused for different purposes could introduce unacceptable risks, such as potential leaks or structural failures. Additionally, not regulating abandoned tanks could result in long-term environmental and health issues, making it imperative for states like Maine to have clear regulations in place.
