Underground Storage Tanks

While there have been significant advancements in equipment, operation, and maintenance, underground storage tanks (USTs) continue to pose risks to the environment and public health.

USTs are commonly used for storing fuel at gas stations, marinas, and other fueling facilities. Leaking underground storage tanks (LUSTs) have a history of contaminating soil, groundwater, and drinking water wells. Cleaning up contaminated sites can require specialized technology and methods, and it is often an expensive undertaking. For more than thirty years, NEIWPCC has taken a lead role in working with state, tribal, territorial, and federal regulators to reduce the number of UST releases and minimize the impacts of LUSTs to the environment and public health.

Training and Information Exchange

NEIWPCC works to develop and implement training and exchange information for those working in the UST field. Most of NEIWPCC’s training is geared toward two key audiences:

NEIWPCC has also hosted the National Tanks Conference & Exposition for over a decade. This event brings together hundreds of UST/LUST professionals, including tank inspectors; cleanup specialists; state, tribal, and territorial regulators; federal regulators; and industry representatives to network and learn about emerging issues, policy, and many other topics. Since 1985, NEIWPCC has published L.U.S.T.Line, a national bulletin covering UST programs in the states, tribes, and territories as well as emerging technologies, case studies, and other topics. L.U.S.T.Line is published twice each year.

UST/LUST Workgroup

NEIWPCC’s UST/LUST Workgroup is comprised of staff from our member states, EPA regional offices, and EPA’s Office of Underground Storage Tanks (OUST). We meet throughout the year to discuss challenges and share success stories related to UST inspections; LUST cleanup; state cleanup funds; and working with UST owners, operators, and contractors within the states.


This website aims to serve as an information clearinghouse for those working or interested in the UST/LUST field. For more information on the UST/LUST program, please contact Drew Youngs.

2015 Federal UST Reg

The 2015 revisions to the UST regulation are effective as of October 13, 2018. Visit U.S. EPA’s website at www.epa.gov/ust to learn more. Additional information on the UST regulation is also available in NEIWPCC’s archives for L.U.S.T.Line, UST and LUST webinars, and the National Tanks Conference.
