requiring permit applications for new landfills to contain a detailed plan for leachate management.

HB 566 requires new landfill permit applicants to submit a detailed plan for managing leachate - the liquid waste that seeps from landfills. This directly affects landfill developers and operators seeking permits for new facilities. The key provision mandates specific technical documentation outlining how leachate will be collected, treated, and prevented from contaminating soil or water. The bill became law on July 22, 2025, and takes effect September 13, 2025.
