There’s a big difference between 5,000-gallon tanks and the 110-gallon variety.

A proposed rule change would formally clear that fact up when it comes to regulating large above ground storage tanks.

Monday, the Wisconsin Department of Agriculture, Trade and Consumer Protection (DATCP) released a draft rule that requires the agency to regulate ASTs that are 5,000 gallons or larger, while also adopting fire and other safety standards.

Owners would need a certified inspector to install and inspect such tanks to license them.

DATCP’s current rule technically requires a certified inspector for tanks 110 gallons or larger, but the agency hasn’t enforced it since 2019.

The change would also bring the rule into sync with state statute, which already set the standard at 5,000 gallons.

DATCP will hold a public hearing on the matter Wednesday, May 8. It would need approval from the governor and legislature to go into effect.
