Ohio Administrative Code › Title 3745 - Ohio Environmental Protection Agency › Chapter 3745-66 - Closure and Post-Closure Under Interim Standards › Section 3745-66-99 - Special requirements for incompatible wastes

Current through all regulations passed and filed through July 1, 2024
(A) Incompatible wastes, or incompatible
			 wastes and materials (see the Appendix of this rule for examples), shall not be
			 placed in the same tank system, unless paragraph (B) of rule
			 3745-65-17
			 of the Administrative Code is complied with.
(B) Hazardous waste shall not be placed in a
			 tank system that has not been decontaminated and that previously held in
			 incompatible waste or material, unless paragraph (B) of rule
			 3745-65-17
			 of the Administrative Code is complied with.

Examples of Potentially Incompatible Waste
Many hazardous wastes, when mixed with other waste or materials
				at a hazardous waste facility, can produce effects which are harmful to human
				health and the environment, such as: heat or pressure; fire or explosion;
				violent reaction, toxic dusts, mists, fumes, or gases; or flammable fumes or
				gases.
Below are examples of potentially incompatible wastes, waste
				components, and materials, along with the harmful consequences which result
				from mixing materials in one group with materials in another group. The list is
				intended as a guide to owners or operators of treatment, storage, and disposal
				facilities, and to enforcement and permit granting officials, to indicate the
				need for special precautions when managing these potentially incompatible waste
				materials or components.
This list is not intended to be exhaustive. An owner or
				operator must, as the regulations require, adequately analyze his wastes so
				that he can avoid creating uncontrolled substances or reactions of the type
				listed below, whether they are listed below or not.
It is possible for potentially incompatible wastes to be mixed
				in a way that precludes a reaction (e.g., adding acid to water rather than
				water to acid) or that neutralizes them (e.g., a strong acid mixed with a
				strong base), or that controls substances produced (e.g., by generating
				flammable gases in a closed tank equipped so that ignition cannot occur, and
				burning the gases in an incinerator).
In the lists below, the mixing of a group A material with a
				group B material may have the potential consequence as noted. Group 1-A
Acetylene sludge
Alkaline caustic liquids
Alkaline cleaner
Alkaline corrosive liquids
Alkaline corrosive battery fluid
