IL HB3672

Establishes a coal refuse energy and reclamation tax credit under the Illinois Income Tax Act for taxable years beginning January 1, 2017 and later.

Provides a credit of $4 per ton of qualified coal refuse used to generate electricity at an eligible facility in Illinois during the previous taxable year.

Defines "eligible facility" as an electric generating facility placed in service before the act's effective date that combusts at least 75% qualified coal refuse by BTU energy value and uses circulating or pressurized fluidized bed combustion with limestone injection and fabric filter systems.

Requires eligible facilities to beneficially use at least 50% of ash produced in the prior calendar year to reclaim mining-affected sites.

Allows excess credits to be carried forward and applied to tax liability for up to 5 following taxable years, with the Department of Commerce and Economic Opportunity administering applications in consultation with the Illinois Environmental Protection Agency.
