§ 103I.685 — Abandonment of Underground Storage Project

Plain-Language Summary

An underground storage project that has received a permit from the Commissioner of Natural Resources cannot be abandoned without the commissioner's written approval. Any openings that connect the underground storage area to the surface — such as wells or tunnels — cannot be filled, sealed, or otherwise closed to inspection unless the commissioner approves and any conditions are met.

Practical Notes
Abandoning an underground gas or liquid storage project requires formal state approval, not just stopping operations. This ensures the state can verify that the site is properly decommissioned and that openings are sealed in a way that protects groundwater. Without this approval, the permit holder remains legally responsible for the site.
