Background

In 2016, the Florida Legislature identified 30 Outstanding Florida Springs that require additional protections to ensure their conservation and restoration for future generations. For impaired springs, these protections are outlined in restoration plans, known as Basin Management Action Plans (BMAPs). These plans are focused on reducing nitrogen pollution sources that may impact the water quality of the springs, including onsite sewage treatment and disposal systems (OSTDS). They include OSTDS remediation plans, with requirements to install enhanced nutrient-reducing OSTDS (ENR-OSTDS, or “nitrogen-reducing systems”). These requirements are in addition to the statutory requirements for ENR-OSTDS established in House Bill (HB)1379, Chapter 2023-169, Laws of Florida.

Where do these requirements apply?

See Springs BMAP Requirements for New and Existing OSTDS (Septic Systems) for an interactive map showing BMAP requirements. For a summary of all ENR-OSTDS requirements for both new and existing systems, including BMAP and statutory requirements, see: Enhanced Nutrient-Reducing Onsite Sewage Treatment and Disposal Systems Requirements.

What approved nitrogen-reducing systems (ENR-OSTDS) can be used to meet these requirements?

In-ground nitrogen-reducing biofilters (INRBs), Florida-approved nitrogen-reducing (NSF 245-certified) aerobic treatment units, and Florida-approved nitrogen-reducing Performance-Based Treatment Systems can be used to meet the ENR-OSTDS standard. 

How can I learn more about these requirements?
