Wis. Admin. Code § PSC 104.05 – Commission procedure.

(1) When a notification of an accident is received, the commission may make an investigation or request a report from the utility.
(2) If notice of an accident is received from a source other than a utility the commission may direct that an investigation be made or request the utility to investigate and report.
(3) If the commission requests a report from a utility, such report shall contain information usually gathered in the case of accident investigations plus any special information requested. Such report shall be transmitted within 6 days after the date the request is made, unless the time therefor shall be extended by the commission. The receipt of a report from a utility does not preclude the commission from making its own investigation.
(4) Every utility shall furnish a report in any specific case not covered by the above, when requested by the public service commission.
