Iowa UST compliance testing

Independent tank testing for Iowa operators regulated under 567 IAC 135, with regulator-ready documentation and no repair conflict.

Regulatory framework

567 IAC 135 is administered by the Iowa Dept. of Natural Resources. 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 Iowa 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 Iowa Dept. of Natural Resources review

Multi-state operators

If Iowa 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.
