A bill for an act relating to the discharge of toxic pollutants associated with coal ash into water sources.

HF 2313 prohibits coal-fired power plants and coal ash landfills from discharging toxic pollutants - including mercury, arsenic, and cadmium - from specific wastewater streams (like flue gas desulfurization water and ash transport water) into water sources. It directly affects existing coal power facilities operating before July 1, 2026, requiring them to comply by December 31, 2029, while new facilities must comply before starting operations. The bill mandates that the environmental department create implementing rules and aims to protect drinking water, groundwater, and communities from avoidable coal ash pollution linked to serious health risks. The law focuses on preventing toxic discharges using existing technology, with clear compliance deadlines for different facility types.
