On March 7, 2017, EPA conditionally approved the Indiana Coal Combustion Residuals (CCR) Part 256 Solid Waste Management Plan (SWMP) Amendment. Indiana has indicated in their CCR Part 256 SWMP that it intends to update its CCR regulations to ensure consistency with the federal CCR regulations in title 40 of the Code of Federal Regulations (CFR) in Part 257 by December 2018. This approval is conditioned on Indiana completing a process to revise their CCR regulations to be consistent with the federal minimum CCR requirements. Until this process is completed, the State will use its existing laws, regulations, and permitting authority to implement the requirements governing the disposal of CCR in CCR landfills and will implement the federal CCR rule for surface impoundments by incorporating the federal requirements by reference under a temporary measure.
