The Underground Storage Tanks (UST) Section is responsible for the regulation of underground storage tank systems used for the storage of regulated substances, primarily petroleum products. Staff in the section work with the owners of sites on the detection, prevention and correction of releases of products from underground tanks.
The section also reviews whether owners and operators can meet financial responsibility requirements to ensure they are able to clean up releases of product. New tank systems must meet minimum design and construction standards and older tank systems must be upgraded to meet these new standards. Investigation and remediation of contamination are based on Iowa’s risk-based corrective action rules and model. All regulated tank systems must be registered with the state.

Storage Tanks Database Web Application
This application is a joint venture between the Iowa Department of Natural Resources (DNR) and the Public Safety State Fire Marshal Office (SFM). It presents in one application all the storage tanks in Iowa containing regulated substances, primarily petroleum products. These consist of Underground Storage Tanks (UST), Leaking Underground Storage Tanks (LUST), and Aboveground Storage Tanks (AST). This site is for public viewing and does not require a login.
The UST are the underground storage of regulated substances, primarily petroleum products. The LUST indicates the report or cleanup of a release of petroleum product. The AST are primarily the aboveground storage of combustible or flammable products.
The database provides information about the UST site location, the site owners, tanks, Risk-Based Corrective Action (RBCA), site classification and remediation. View the current status of underground storage tank and leaking underground storage tank sites.
Storage Tanks Database Web Application Help Document will assist in the navigation of the database.

Delivery Prohibition to UST Sites that Have Not Been Issued Annual Tank Management Tags Memo
Annual tank tags may not have been issued due to non-payment of the tank management fee, temporary closure, lack of current pollution liability insurance, no trained Class A/B operator or an outstanding violation. Red tags are attached to the fill port to prohibit fuel delivery due to outstanding violations.
Please read the above letter and review the fuel prohibition site list. Remember, if you deliver to an underground storage tank that does not have a current yearly tag or is red tagged, you are subject to enforcement action and fines.
Check the delivery prohibition list often as it will change as sites come into compliance. Be sure to remind your drivers to check for a current tags or a red fuel delivery prohibition tag. Do not deliver fuel simply because they are a regular customer, claim they have the tag or that the red tag was lifted even though the site is still on the fuel prohibition list.

After accessing the web site, a User’s Guide is available to assist with navigation.
At this time, only a small portion of all LUST files are available for public viewing, but more will become available as this project progresses. If you cannot find records for a LUST site property, please contact DNR Records Center at 515-725-8480 or DNR.Records@dnr.iowa.gov
The goal of our Electronic Records Project is to index and digitize all records related to LUST facilities and make these available through this web site. However, given there are nearly 6,600 LUST site files stored in various forms (film, microfiche, paper, electronic), it is expected the project will take some time to complete. Files associated with LUST sites that have met regulatory closure are first in line to be digitized and uploaded. This project will help us organize and maintain permanent documents, make records readily available to the public, and free up storage space currently held by paper and filmed records at the DNR Records Center.
