Wisconsin UST testing preparation checklist
What to send before a Wisconsin UST testing visit: facility details, previous reports, equipment information, access and delivery schedule.
Send the notice and facility information
If an inspector has requested testing, send the full notice, including the listed items and due date. If the work is routine, send the previous reports. Include the site address and DATCP facility ID so the records can be matched to the right facility.
Tell us who can provide access and who should receive the report. For multiple sites, list each facility separately with its own address, ID and deadline.
Gather the existing testing records
Start with the most recent reports for the work being requested. Wisconsin publishes separate forms for different tests. These are useful identifiers when you are looking through a facility file.
| Record | DATCP form |
|---|---|
| Annual underground tank system functionality verification | TR-WM-139 |
| Line leak detector functionality test | TR-WM-123 |
| Tank precision tightness test | TR-WM-152 |
| Line precision tightness test | TR-WM-125 |
| Pre-operational tank tightness test | TR-WM-155 |
These records cover different work. An annual functionality report does not stand in for every precision test or containment test. Compare tank tightness, line tightness and detector testing.
Identify the equipment
Send what you have. Tank and line information helps establish the scope and equipment needed for the visit. If a detail is unknown, mark it as unknown.
- Tank numbers, products and capacities.
- Which dispensers each product line serves.
- Automatic tank gauge make and model.
- Mechanical or electronic line leak detectors, if known.
- Number of spill buckets, tank sumps and dispenser sumps.
- Recent equipment changes or repairs.
Arrange access and operating time
Testing may require access to the tank field, pump equipment, dispensers and monitoring console. Confirm who has the keys and when they will be at the site. Let us know about vehicle traffic, locked areas or other contractors working in the same area.
Fuel level and delivery timing can affect a tank test. Send the planned delivery times and your normal operating hours. We will confirm the operating restrictions and test conditions for the selected method before the visit. Avoid arranging a fuel delivery or changing the tank level just to prepare for a test until that plan has been discussed.
Flag conditions that need attention before the visit
Tell us about current alarms, slow flow, water or fuel in containment, damaged covers and any operating restriction. Include the console messages and the time they appeared. This helps distinguish routine testing from an unresolved problem that needs a different scope.
If you are working under an inspection notice, keep that due date visible when scheduling. The testing appointment and any agency deadline are separate dates.
Keep the report with the facility records
After testing, file the signed report and its supporting records under the correct facility and equipment. Review any failed result, limitation or follow-up item with the person responsible for the site. Where a report needs to be submitted, confirm who is handling that submission.
The facility's testing schedule depends on the installed equipment, release detection method and applicable Wisconsin requirements. We confirm the work being ordered from those details; this preparation checklist does not assign a single testing interval to every site.
Request testing
Send the facility address, ID, previous reports and the requested scope. Doug Metzker will discuss the equipment and schedule with you. Request UST testing or call (414) 301-3645.
