Solid Waste Disposal - As enacted, makes various changes to law relative to solid waste disposal, including, but not limited to, declaring that it is the policy of this state to plan for sufficient landfill capacity to dispose of solid waste that is not recovered or recycled; requiring each solid waste region to develop a plan that includes a narrative identifying where waste will be disposed and managed for the next 10 years; and requiring each solid waste region to submit a new or revised plan by July 1, 2028. - Amends TCA Title 4; Title 5; Title 6; Title 7 and Title 68, Chapter 211.

HB 2516 reduces the timeframe for notifying appointing authorities about vacancies on Tennessee's underground storage tanks and solid waste disposal control board from 90 to 45 days. This procedural bill directly affects the board members and the government bodies that appoint them, requiring quicker communication when a position becomes vacant. The change amends specific sections of Tennessee law (TCA Titles 4, 5, 6, 7, and 68) related to solid waste management procedures. It does not alter waste disposal rules or environmental standards, only the administrative process for board vacancies.
