Modifies provisions relating to solid waste disposal area permits

This bill updates the rules for obtaining permits to build or operate solid waste disposal areas and processing facilities in Missouri. It requires operators to secure specific construction and operating permits from the state department, while also establishing a process for public notification and community involvement sessions before new sites are approved. The legislation mandates detailed geological and hydrologic investigations, requires proof of financial responsibility to cover future cleanup costs, and restricts permits for landfills located in flood-prone areas. Additionally, it clarifies that existing facilities authorized before 1995 are considered permitted and exempts certain water treatment facilities from needing new solid waste permits if they already hold valid water quality permits.
