Two weeks after removing 3M striping tape from its Approved Products List, WisDOT is issuing updated guidance, giving contractors several options.
For projects let prior to September 2025, contractors can:
- Continue to use previously approved permanent 3M tape if they can provide documentation (including batch numbers) showing the permanent tape was manufactured to match the contract’s APL
- File a change order for marking line grooved wet reflective epoxy and use that instead of tape
- Consider a change order if contractor has unapproved new formula 3M tape and is charged a restocking fee (must provide documentation)
- Similar rules apply for temporary removable tape
You can read and print the entire updated guidance HERE.
Background
3M sent the Department an email on June 27, 2025 stating that 3M reformulated its tape products to remove intentionally added PFAS. This change affects all of 3M’s permanent tapes and some removable tapes.
This is in violation of the WisDOT APL requirements due to no National Transportation Product Evaluation Program testing being completed.
Therefore, all permanent and removable 3M tapes are being removed from WisDOT’s APL. This is effective with any tape having a manufacture date after July 1, 2025.
For projects beginning with the October 2025 letting, grooved wet reflective epoxy will be used instead of grooved permanent tape.
