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.
Web-Based Risk Based Corrective Action (RBCA) Application
The Iowa DNR UST Section web-based application will be used for new and revised Tier 2 Site Cleanup Reports, and Site Monitoring Reports.This does not apply to non-granular bedrock and granular bedrock sites. Please review the FAQ document posted below prior to using the new application for RBCA purposes.

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.

The 2024 Annual Tank Management Renewal of Underground Storage Tanks will be December 1, 2023 - January 15, 2024.
Every year all owners with active and temporarily closed regulated underground storage tanks greater than 1,100 gallons must complete the annual renewal process. This includes sites in delivery prohibition status.
You will be able to login, complete and submit your renewal online through DNR’s UST Online Renewal System beginning December 1. To pay by mail, complete the current renewal online as normal, print your completed form, sign/date it, attach a check to it and mail it to the address at the bottom of the form. Checks received without a form will be returned to the sender. If you chose to pay online the payment portion will show you that there will be a $1.50 fee. Credit card and debit card users will have the $1.50 fee and an additional 2.5% fee. Debit cards are allowed to be used but only if the card has a Visa, Mastercard or another acceptable logo on it. The screen will show you all of the credit card types allowed. Please note, you are allowed to choose to pay using E-check, credit card or debit card for your renewal(s) ‘once’ which avoids creating a separate payment method storage account. The payment storage account would require a separate username and password. We anticipate these options will continue to be available in future renewal seasons, allowing the ‘once’ option to be used each renewal season.
The annual tank management fee of $65 per tank compartment is due by January 15.
Begin Online Renewal
A late fee of $250 per tank compartment will be applied after March 1, 2024.
The DNR is in the process of adopting state regulations in response to changes in federal UST requirements. A number of significant changes will be made, including these new requirements:
The EPA has indicated the first cycle of the three-year testing must be completed by October 13, 2021, for those facilities subject to testing, regardless of when the proposed state rules become effective. The DNR is not currently requiring this testing for existing systems, but we are providing this notice so owners can plan for testing once state regulations are finalized. Please check the DNR UST/LUST Regulations tab on our webpage for draft rule documents and further updates.

At this time, a small portion of all LUST files and several UST files are available for public viewing, but more will become available as this project progresses.
The goal of our Electronic Records Project is to index and digitize all records related to LUST and UST facilities and make these available through this web site. However, given there are site files stored in various forms (film, microfiche, paper, electronic), it is expected the project will take some time to complete.
If you cannot find records for a LUST or UST site property, please submit a Request or contact DNR Records Center at firstname.lastname@example.org.
