(b) A description of the proposed action, and alternative actions considered by the public utility, to reduce sulfur dioxide emissions to levels required by the Clean Air Act at each affected unit;
(c) A description of the proposed action, and alternative actions considered by the public utility, to comply with nitrogen oxide emission rates required by the Clean Air Act at each affected unit;

The commission shall by order approve or disapprove plans to implement compliance submitted by public utilities within 8 months after the date of filing. Approval of a plan submitted by a public utility shall establish that the utility’s plan to implement compliance is prudent and the commission shall retain jurisdiction to determine in a subsequent proceeding that the actual costs of implementing the compliance plan are reasonable; provided, however, that nothing in this section shall be construed to interfere with the authority of the Department of Environmental Protection to determine whether a public utility is in compliance with ss. 403.087 and 403.0872 or the State Air Implementation Plan for the Clean Air Act.
