Maine UST Directory

Maine faces ongoing environmental considerations related to underground storage tanks (USTs). The state has 6,041 registered UST facilities, and a significant 3,107 documented LUST (leaking underground storage tank) release sites highlight a history of contamination incidents. Currently, 8 of these releases are classified as "Open," indicating active cleanup requirements. With 2,173 active USTs and 14,072 closed tanks, continuous UST monitoring and diligent environmental due diligence are essential to mitigate risks and prevent future contamination.

The potential for soil and groundwater contamination from USTs underscores the importance of robust protection measures. Cities with high concentrations of UST facilities and associated releases include Portland (221 facilities, 183 releases), Bangor (177 facilities, 94 releases), Augusta (148 facilities, 63 releases), Auburn (119 facilities, 77 releases), and Lewiston (118 facilities, 81 releases). Protecting vital groundwater resources is paramount, and comprehensive UST data, such as that sourced from the EPA UST Finder program, is crucial for effective environmental management and public health.
