Notification Required

As required by ATCP 93, the Janesville Fire Department must be notified at least 5 days before an installation (including upgrades) or 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 days in advance, please call again 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.

Form processing

Certified installation or closure contractors are responsible for completing the required checklists and forms. We will not grant final approval until the contractors have submitted the checklists to the Janesville Fire Department for signature and filing with the Wisconsin Department of Agriculture, Trade, and Consumer Protection (DATCP).

A Tank Closure Application is available at the Janesville Fire Department or it can be downloaded by clicking the folder icon at the top of this webpage. Return this form with payment to the Janesville Fire Department in person, by mail, or by fax. You can obtain all other forms through the DATCP.

Plans for the installation or removal and the associated letter of conditional approval must be on-site always.


While on-site, the Janesville Fire Department may record site and worker safety violations and forward such violations to OSHA. The Department is not responsible for enforcement of safety requirements, but we will not overlook or permit situations that pose a severe fire or life safety threat.

Janesville Fire Department personnel will not jeopardize their personal safety to inspect the project. Do not expect the inspector to enter the excavation, jump to the top of the tank, or otherwise violate safety standards.


As required by the State of Wisconsin, tank system installation, removal, testing, relining, cleaning, and site assessments will be supervised by a person holding an appropriate certification. Inspection personnel will require proof of that certification.

Proof of certification must be submitted when requesting approval from Janesville Fire Department for tank system work.

Tank System Removal and Closure

Tank removal must comply with ATCP 93 and COJ General Ordinance 8.36.085. The ordinance requires approval for the closure, change-in-service or temporary closure of any tank system. "Tank system" includes aboveground and underground storage tanks more than 60 gallons and system components to include, but not limited to: tanks, piping, vents, leak detection, cathodic protection, and spill/overfill protection systems.

        1.    Required submittal.

Submit the City of Janesville Tank Closure Application, three copies of a site plot plan, three copies of the site assessment plan, and the required fee for approval to: Janesville Fire Department, Attn: Fire Marshal, 303 Milton Avenue, Janesville WI 53545.

        2.    Site Plot Plan Requirements.

The site plot plan must be drawn to scale and include the following:

    • property lines
    • all buildings or structures
    • all tanks and piping
    • adjacent streets
    • overhead and underground utilities
    • limits of the excavation
    • temporary location of excavated dirt and backfill

        3.   Fees.

You must submit all required fees with the closure application, as stated previously. Make checks payable to the City of Janesville. Click the folder icon at the top of this page for a listing of inspection fees.

        4.    Required Inspections.

A Janesville Fire Department certified tank Inspector must be on-site when the tank is being removed from the ground. The tank cannot be removed until an inspector verifies the purging or inerting (making the atmosphere within the tank nonexplosive) of the tank. The inspector will document the condition of the excavation after the tank has been removed.

Note: When scheduling inspection times, carefully estimate when the tank will be excavated and purged or inerted. When the inspector is waiting at another job site, they cannot be available to inspect your job site.

        5.    Monitoring Equipment.

A calibrated combustible gas and oxygen indicator must be on-site to monitor the tank atmosphere. An individual must be competent in the use of the equipment.

        6.    Condition of Approval.

We will grant approval to the certified individual or company submitting the application. This person or company will be responsible for the tank removal. All violations and/or required corrections will be addressed to the responsible party.
