The Eau Claire Fire Prevention Division is responsible for the inspection of all Underground and Aboveground Storage Tanks (UST/AST) used for petroleum storage.  The department is contracted by the State of Wisconsin to conduct such service within the city of Eau Claire.


Notification Required

As required by SPS 310, the Eau Claire Fire Department must be notified at least 5 days before an installation (including upgrades) and 15 days before a system closure. When scheduling an inspection with this office, please include the time you expect to need an inspector at the site. If the exact time is not available when calling 5 or 15 days in advance, please call at least 24 hours in advance to request an inspector at a given time. The Fire Department can provide timely service if you schedule the inspection in advance.
