HB379

Hawaii HB379 mandates denitrification capacity for new or modified individual wastewater systems near shorelines or likely to pollute groundwater.

Hawaii HB379 requires newly installed or modified individual wastewater systems near shorelines or likely to pollute groundwater to include denitrification capacity. This applies to systems within 200 feet of a shoreline or below 1,500 feet above sea level with specific soil conditions. Denitrification capacity means certification to meet NSF and ANSI standards. The bill aims to protect nearshore waters, supporting ecosystem resilience and public health, especially coral reefs.
