Wis. Stat. § 323.31
From the appropriations under s. 20.465(3) (b) and (s), the adjutant general shall make payments to retail electric cooperatives, as defined in s. 16.957(1) (t), to local governmental units, as defined in s. 19.42(7u), and to federally recognized American Indian tribes and bands in this state for the damages and costs incurred as the result of a disaster if federal disaster assistance is not available for that disaster because the governor's request that the president declare the disaster a major disaster under 42 USC 5170 has been denied or because the disaster, as determined by the department of military affairs, does not meet the statewide or countywide per capita impact indicator under the public assistance program that is issued by the federal emergency management agency. To be eligible for a payment under this section, the retail electric cooperative, local governmental unit, or tribe or band shall pay 30 percent of the amount of the damages and costs resulting from the disaster. The department of military affairs shall promulgate rules establishing the application process and the criteria for determining eligibility for payments under this section.
