Reasonable Assurance Plans (RAPs): Category 4b Assessments and Documentation
EPA regulations allow states to place certain impaired water bodies into Category 4b of the Integrated Report Categories instead of Category 5 – Impaired and needs a TMDL. The Florida Watershed Restoration Act (Section 403.067(4), F.S.) explicitly allows DEP to not list impaired waters under Category 5 if they already have control programs in place that will ensure water quality standards will be restored. These types of waterbodies – impaired, but with control programs already being implemented to reduce pollutant loadings – are placed in assessment Category 4b for Clean Water Act section 303(d) reporting purposes.To assist stakeholders in developing approvable Reasonable Assurance Plans, the department created aGuidance on Developing Restoration Plans as Alternatives to TMDLs – Assessment Category 4b and 4e Plans.
