WisDOT’s policy is that no asbestos-containing material should be used in the construction or maintenance of a bridge facility.
All buildings that are to be demolished or sold and moved are required to be inspected for asbestos prior to demolition or removal. These inspections are typically done during the Real Estate process.
Requesting Inspections - Bridges
To request a bridge inspection, fill out the
asbestos worksheet and email it, along with a location map, and photos of the structure (if available) to
DOT Hazmat Unit.
As of April 2005, all bridge asbestos inspections for any project that will be administered by WisDOT, including local road bridges, projects designed by consultants under contract to WisDOT, and projects designed in-house by WisDOT will be conducted through a contract administered by the Bureau of Technical Services, Environmental services section.
Scheduling of the inspections will be prioritized by environmental document date, and PS&E date. The inspections are grouped to reduce overall costs and mobilization charges.
Requesting Inspections - Buildings
To request a pre-demolition or pre-move building inspection fill out the
building inspection worksheet, and email it, along with a location map and photos of the structure (if available) to
DOT Hazmat Unit.
There are several different special provisions for asbestos, which one you use will depend on the findings of the inspection. The STSP index includes guidance on when to use each of the STSPs:

Q. I thought it was illegal to use asbestos?
A. Asbestos mining ended in the U.S. in 2002, however the US still imports over a thousand tons of asbestos every year for use in roofing, coatings and various other materials.
Q. Where is asbestos commonly found on bridges?
A. The three most common locations are in the gaskets or grout in the expansion joints in parapet walls, in the grout under railing bolt plates, and in the tar-like material used to seal the tops of wooden posts in the wing walls.
Q. Can you tell if a material is asbestos containing just by looking at it?
A. No. The fibers are so small they cannot be detected without a microscope. This is why we have to sample the material to determine if it contains asbestos.
Q. Do I submit culverts for inspection as well?
A. No. The inspections are currently limited to those structures meeting the federal definition of bridges. (Those that currently have a B- or P- number in the Highway Structures Information System (HSIS).
The exception is a culvert which has a suspect material on it (e.g. caulk, gasket, patching material).
Section NR 725.05 Wis. Admin. Code requires notification of appropriate units of government when a site closure request is being made with residual soil or groundwater contamination or certain continuing obligations within a right-of-way.
Use DNR form 4400-286 available on the DNR website for notification.
For state trunk, interstate and U.S. highways, all notifications of contamination in highway rights-of-way should be directed to the
DOT Hazmat Unit via email or by U.S. mail or certified mail to:
DOT BTS-ESS Hazmat Unit
P.O. Box 7965
ROOM 5 South

See FDM 21-35-25 for applicability:
Having completed a Phase 1 investigation for the improvement under consideration, the region has determined that further investigation of sites is merited. Those investigations are in the process of being scheduled. The WDNR and possibly affected parties will be notified of the results. The region will work with all concerned to insure that the disposition of any petroleum contamination is resolved to the satisfaction of the WDNR, WisDOT, and FHWA before acquisition of any questionable site, and before advertising the project for letting.
Non-petroleum sites will be handled on a case-by-case basis with detailed documentation and coordination with FHWA as needed.
