Hawaii HB2245 mandates denitrification capacity for new or modified individual wastewater systems near shorelines.

Hawaii HB2245 amends the Revised Statutes to require new or modified individual wastewater systems within 200 feet of a shoreline to include denitrification capacity, defined as a minimum 50% reduction in nitrogen. This applies to systems installed or modified after July 1, 2027. The bill also mandates denitrification capacity for systems within 1,200 feet of a shoreline in areas with highly porous soils. The Department of Health will reduce leach field requirements for systems with denitrification capacity.
