## Abstract

The Environmental Protection Agency (EPA) is notifying the public that we have received from Indiana requests for withdrawals of the previously approved state plans and notification of negative declarations for Commercial and Industrial Solid Waste Incineration (CISWI) units and Sewage Sludge Incineration (SSI) units. The Indiana Department of Environmental Management (IDEM) submitted its CISWI withdrawal and negative declaration by letter dated July 31, 2017 and its SSI withdrawal and negative declaration by letter dated July 31, 2017. IDEM notified EPA in its negative declaration letters that there are no CISWI or SSI units subject to the requirements of the Clean Air Act (Act) currently operating in Indiana. On October 3, 2018, EPA published a notice of proposed rulemaking for these negative declarations.
