10. Analysis and Supporting Documents Used to Determine the Effect on Small Business or in Preparation of an Economic Impact Report: The proposed rule will affect four electric utility companies that are CCR landfill owners and operators. There are approximately 18 existing and new CCR landfill units under federal regulation, which when combined represent six solid waste landfill facilities under Wisconsin regulation. None of the electric utility companies meet the definition of a small business under s. 227.114(1), Wis. Stats.
11. Effect on Small Business (initial regulatory flexibility analysis):
The rule is not likely to have an impact on small businesses. CCR landfills are operated by electric utilities that do not meet the definition of a small business under s. 227.114(1), Wis. Stats. The proposed rule would modify Wisconsin regulations to incorporate requirements of the federal rule into Wisconsin’s existing rules to allow Wisconsin to apply for a CCR state permit program. Most of the changes in the proposed rule have already been implemented by the federal government and facilities have already complied with the federal rule. Any additional requirements as a result of the proposed rule are procedural requirements for initial permitting or related to the consolidation of state and federal requirements. Any additional cost as a result of this proposed rule will be related to a facility’s plan preparation for initial permitting and department review of plans or annual reports.
