AI Summary
This bill, effective July 1, 3000, mandates that starting July 1, 2027, any new or modified individual wastewater systems, which are private systems for treating sewage from a single home or building, must include "denitrification capacity" if they are located within 200 feet of the shoreline, or within 1,200 feet of the shoreline in specific counties with highly porous soils (defined as soil with over 75% porosity). Denitrification capacity means the system is certified to reduce nitrogen by at least 50%, meeting specific national standards. In recognition of this enhanced treatment, the Department of Health is required to lessen the requirements for disposal systems connected to these advanced wastewater systems, aiming to protect nearshore waters and coral reefs from harmful nitrogen pollution.
