Solid waste matters.

Establishes the central Indiana waste diversion pilot project (pilot project). Requires the department of environmental management to: (1) develop pilot project application forms; (2) make the forms available on or before July 1, 2022; (3) accept applications through October 1, 2022; and (4) provide recommendations to the Indiana recycling market development board (board) on or before December 1, 2022. Requires the board to award not more than $4,000,000 in total to applicants chosen to participate in the pilot project. Limits the pilot project to Marion County. Amends the definition of "solid waste"to exclude materials that are used in creating a product and that meet other conditions. Provides that: (1) a transfer station or treatment, storage, or disposal facility that holds a permit to handle hazardous waste may also handle solid waste; (2) solid waste that is managed at a transfer station or a treatment, storage, or disposal facility shall not be allowed to come into direct contact with hazardous waste, and any solid waste that does come into direct contact with hazardous waste shall then be managed as hazardous waste; and (3) the environmental rules board (rules board) shall amend 329 IAC 11 to conform to these provisions. Requires the rules board to expeditiously adopt by rule all waste regulation exemptions or exclusions as that are adopted by the United States Environmental Protection Agency (EPA) and set forth in the federal rule on the identification and listing of hazardous waste. Provides that until certain federal rule amendments that were adopted by the EPA on May 30, 2018, are adopted by the rules board, those amendments apply to the identification and listing of hazardous waste in Indiana just as if the amendments were already incorporated by reference into the rules of the rule board on the identification and listing of hazardous waste. Provides that: (1) the disposal of non-hazardous coal mining waste and coal combustion residuals at a surface coal mining facility; and (2) the use of coal combustion residuals as raw material for manufacturing another product or for eight other particular uses; are not subject to regulation under the solid waste rules. Makes corresponding changes.
