Minnesota UST Directory

Minnesota manages a substantial number of underground storage tanks (USTs), with 14,133 registered UST facilities across the state. A significant environmental concern stems from leaking underground storage tanks (LUSTs), which have resulted in 11,477 documented release sites. Currently, 407 of these releases are classified as "Open," indicating ongoing cleanup requirements. The state oversees 10,638 active USTs, in addition to 34,457 closed tanks. This comprehensive data is sourced from the EPA UST Finder program.

The prevalence of USTs and associated releases is particularly notable in urban areas. Minneapolis records 735 facilities and 797 releases, while Saint Paul has 607 facilities and 624 releases. Other cities, including Duluth (334 facilities, 379 releases), Rochester (245 facilities, 205 releases), and Bloomington (182 facilities, 146 releases), also show significant numbers. These figures highlight the critical importance of continuous UST monitoring, diligent environmental due diligence, and robust measures to protect Minnesota's groundwater resources from potential contamination.
