The proposed rules would establish eligibilities; prerequisites for grant-in-aid; project priorities; procedures for obtaining grants; maximum grant amounts; grant percentages; requirements for planning, design, and construction; procurement; and responsibilities of the parties to grant agreements. Most construction grants would be a subsidy to the project sponsor’s State Revolving Fund loan repayments, or some other suitable funding mechanism. The loan repayment subsidy for construction activities would be based on a formula that would incorporate the project sponsor’s affordability index and a weighted average of its priority factors. The affordability index is an empirical number that is generated by a computer program developed for the Department by Florida State University and is based on a statistical analysis of the project sponsor’s median household income, poverty and unemployment census statistics from the most recent decennial census. Allowances would be eliminated. All elements included in a State Revolving Fund loan repayment would be eligible for grant funding at the grant percentage.
