Who it's for
Gas station and fuel facility operators who keep routine walkthrough records for underground storage tanks.
Key features
- Facility and Tank MasterRegister each facility and its tanks so every walkthrough is tied to the right site.
- 30-Day Walkthrough RecordLog a walkthrough with an editable checklist template covering common items such as spill buckets and release detection equipment. Mark each item OK, NG, or N/A, and attach a note and photo. The next walkthrough due date is calculated automatically as your last completed walkthrough plus 30 days, with a due-date badge on every facility.
- Delivery-Time ExceptionFor facilities on an irregular delivery schedule, switch to a delivery-time walkthrough mode that logs the check at time of fuel delivery instead of on a fixed monthly cadence, and still tracks a rolling one-year record retention view.
- Annual ItemsLog a separate set of annual items using its own editable template, independent of the 30-day checklist.
- Corrective Action TrackingAny item marked NG stays flagged on the facility until you log a corrective action record — there is no way to clear a failed item without one.
- Reports for InspectorsGenerate a period PDF suitable to hand an inspector, plus CSV export of every table.
Checklist items are written in general, editable terms and are not copied from any regulation or standard. This app does not certify compliance with any federal, state, or local requirement, does not claim nationwide or universal compliance, and does not replace tank monitoring equipment. Confirm your facility's actual obligations with the implementing agency for your jurisdiction — items specific to your agency can be added as your own template fields.
