New Tank Systems (Wis. Admin. Code §​ ATCP 93.100)

  • Installation Plans are to be submitted to the Department of Agriculture, Trade and Consumer Protection (DATCP)​ for approval on form TR-WM-126. With the installation of a new tank system, estimated cost of a plan review for alternative fuels will vary dependent on if other tank systems are being installed at the same time. Fee amounts are determined by Wis. Admin. Code § ATCP 93.1605 and can be found on TR-WM-126 and other forms.

  • Specific to an alternative ​fuels tank system installation, Part I of the TR-WM-132 Alternative Fuels form available on our forms page shall also be submitted with the installation plans. This form requires the tank system installer or a professional engineer to verify that the tank system materials are compatible with the fuel being stored.

  • All tank systems, whether alternative fuel or not, shall be installed by a Wisconsin-certified installation company or under the direction of a professional engineer.
