The bill H.425 mandates the Secretary of Natural Resources to develop and submit a proposed regional long-term management plan for the safe and cost-effective disposal of septage, sludge, and biosolids by January 15, 2025. The plan aims to mitigate environmental and public health risks associated with these materials. It includes provisions for establishing multimunicipality districts for regional management, identifying existing wastewater treatment facilities as acceptance sites, addressing administrative and operational barriers, and facilitating intermunicipal agreements for shared costs. Additionally, the plan will assess options for managing outputs from these facilities, including the handling of contaminants like PFAS.

Key definitions are introduced in the bill, including terms such as "biosolids," "septage," "sludge," and "PFAS," which clarify the scope of the management plan. The Secretary is also required to provide public notice and allow for a 30-day comment period before submitting the final plan to the General Assembly. The act is set to take effect on July 1, 2025.
