North Dakota Administrative Code › Title 33.1 - Department of Environmental Quality › Article 33.1-24 - Hazardous Waste Management › Chapter 33.1-24-05 - Standards for Treatment, Storage, and Disposal Facilities and for the Management of Specific Hazardous Wastes and Specific Types of Hazardous Waste Management Facilities › STANDARDS FOR FACILITIES OPERATING UNDER A STANDARDIZED PERMIT › Appendix III - Examples of Potentially Incompatible Waste

Current through Supplement No. 393, July, 2024
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 (1) heat or pressure, (2) fire or
					 explosion, (3) violent reaction, (4) toxic dusts, mists, fumes, or gases, or
					 (5) 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 (for example, adding acid to water
					 rather than water to acid) or that neutralizes them (for example, a strong acid
					 mixed with a strong base), or that controls substances produced (for example,
					 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.
