A person in the business of owning or operating a nuclear power plant or dry cask storage facility located in Minnesota, shall pay quarterly assessments to cover the cost of nuclear power plant emergency response programs necessary to deal with incidents resulting from either facility. An assessment of up to one quarter of the projected annual cost must be paid to the state director on July 1 of each year. An assessment must be billed by the state director based on actual costs for each quarter of the fiscal year starting with the first quarter ending September 30. The July 1 assessment must be deducted from the final quarterly billing for the fiscal year. The assessment collected must be credited to the nuclear safety preparedness account in the special revenue fund.
