Proposed Regulations Available for Public Comment
6 NYCRR Part 360 & 363 Treatment and Disposal of Landfill Leachate
Notice of Proposed Rule Making
Notice is hereby given that the New York State Department of Environmental Conservation (DEC) published a Notice of Proposed Rule Making with the New York State Department of State on July 1, 2026, to amend 6 NYCRR Part 360 Series Solid Waste Management Facilities.
DEC is proposing to amend the solid waste regulations to include new requirements for the treatment of leachate generated at municipal solid waste landfills and at construction and demolition debris landfills that have leachate collection systems. Improved management of landfill leachate will address the potential environmental impacts posed by landfill contaminants. Landfill leachate has traditionally been sent for disposal at WRRFs. While this is a standard method for management of leachate nationwide, it allows contaminants in the leachate to leave the concentration point that the landfill represents and to be sent to treatment facilities that are not designed to treat those contaminants. The goal of this rulemaking is to minimize the re-introduction of those contaminants into the environment. The proposed revisions to Part 360 and Part 363 require leachate from currently active MSW landfills and currently active C&D debris landfills that have leachate collection systems to be treated to remove contaminants and ensure the proper disposal of those contaminants. The treatment must occur prior to delivery of any treated leachate stream to a WRRF or other authorized discharge location. The concentrated residual waste resulting from treatment must be properly disposed.
