Alabama Administrative Code › Title 335 - ALABAMA DEPARTMENT OF ENVIRONMENTAL MANAGEMENT › LAND DIVISION - HAZARDOUS WASTE PROGRAM › Chapter 335-14-6 - INTERIM STATUS STANDARDS FOR OWNERS AND OPERATORS OF HAZARDOUS WASTE TREATMENT, STORAGE, AND DISPOSAL FACILITIES › Appendix V - Examples Of Potentially Incompatible Waste

Current through Register Vol. 42, No. 9, June 28, 2024
Many hazardous wastes, when mixed with other waste or
				  materials at a hazardous waste facility, can produce effects which are harmful
				  to human or animal health or 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
				(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.
