Rule 3745-525-01 | Scope and purpose, 40 C.F.R. 257.50.
(A) "Standards for the Disposal of Coal Combustion Residuals in Landfills and Surface Impoundments," 40 C.F.R. 257.60 to 257.107, 80 Fed. Reg. 21468 (April 17, 2015); as amended at 80 Fed. Reg. 37988 (July 2, 2015), 81 Fed. Reg. 51807 (August 5, 2016), 83 Fed. Reg. 36451 (July 30, 2018), 85 Fed. Reg. 53561 (August 8, 2020), 89 Fed. Reg. 39099 (May 8, 2024), and 89 Fed. Reg. 88653 (November 8, 2024) are hereby adopted by Ohio EPA and incorporated by reference herein, subject to the exceptions, revision, and additions in this chapter.
(B) This chapter applies to owners and operators of new and existing landfills and surface impoundments, including any lateral expansions of such units that dispose or otherwise engage in solid waste management of CCR generated from the combustion of coal at electric utilities and independent power producers. Unless otherwise provided in this chapter, these requirements also apply to disposal units located off-site of the electric utility or independent power producer. This chapter also applies to any practice that does not meet the definition of a beneficial use of CCR.
(C) This chapter also applies to inactive CCR surface impoundments at active electric utilities or independent power producers, regardless of how the electricity is currently being produced at the facility.
(D) This chapter does not apply to a CCR management unit or to a legacy CCR surface impoundment, as those terms are defined in 40 C.F.R. 257.53.
[Comment: CCR management units and legacy CCR surface impoundments are subject to 40 C.F.R. 257 administered by the United States environmental protection agency.]
(E) [Reserved.]
(F) This chapter does not apply to wastes, including fly ash, bottom ash, boiler slag, and flue gas desulfurization materials generated at facilities that are not part of an electric utility or independent power producer, such as manufacturing facilities, universities, and hospitals. This chapter also does not apply to fly ash, bottom ash, boiler slag, and flue gas desulfurization materials, generated primarily from the combustion of fuels (including other fossil fuels) other than coal, for the purpose of generating electricity unless the fuel burned consists of more than fifty per cent coal on a total heat input or mass input basis, whichever results in the greater mass feed rate of coal.
(G) This chapter does not apply to practices that meet the definition of a beneficial use of CCR.
(H) This chapter does not apply to CCR placement at active or abandoned underground or surface coal mines.
(I) This chapter does not apply to municipal solid waste landfills that receive CCR.
