Wisconsin UST compliance testing

Independent tank testing for Wisconsin operators regulated under ATCP 93, with regulator-ready documentation and no repair conflict.

Regulatory framework

ATCP 93 is administered by the WI Dept. of Agriculture, Trade and Consumer Protection. It establishes technical standards for tank systems including leak detection, periodic testing, release reporting and closure requirements.

40 CFR 280 applies in parallel as the federal floor. USTEX protocols satisfy the state overlay and the federal standard in a single engagement, so one test produces one document that answers both.

What Wisconsin operators typically need

• Annual line leak detector functional testing at 3.0 gph, 10 psi
• Periodic tank tightness at the 0.1 gph threshold
• Spill prevention and overfill operability verification
• Documentation formatted for WI Dept. of Agriculture, Trade and Consumer Protection review

Multi-state operators

If Wisconsin is one of several states in your footprint, the program runs on one schedule and one documentation standard across all of them. USTEX is active in twelve states, so a portfolio does not need a different vendor per jurisdiction.
