Code of Maryland Regulations › Title 26 - DEPARTMENT OF ENVIRONMENT › Part 3 - SUBTITLES 13-18 › Subtitle 13 - DISPOSAL OF CONTROLLED HAZARDOUS SUBSTANCES › Chapter 26.13.02 - Identification and Listing of Hazardous Waste › Section 26.13.02.19 - Discarded Commercial Chemical Products, Off-Specification Species, Containers, and Spill Residues of These

Current through Register Vol. 51, No. 14, July 12, 2024
The following materials or items are hazardous wastes if
					 and when they are discarded or intended to be discarded as described in
					 Regulation .02A(2)(a) of this chapter, when they are mixed with waste oil or
					 used oil or other material and applied to the land for dust suppression or road
					 treatment, when they are otherwise applied to the land instead of their
					 original intended use or when they are contained in products that are applied
					 to the land instead of their original intended use or when, instead of their
					 original intended use, they are produced for use as (or as a component of) a
					 fuel, distributed for use as a fuel, or burned as a fuel:
A. Any commercial chemical product, or
				  manufacturing chemical intermediate, having the generic name listed in §E, F,
				  G, or H of this regulation.
B. Any
				  off-specification commercial chemical product or manufacturing chemical
				  intermediate which, if it met specifications, would have the generic name
				  listed in §E, F, G, or H of this regulation.
C. Any residue remaining in a container or
				  inner liner removed from a container that has been used to hold any commercial
				  chemical product or manufacturing chemical intermediate having the generic name
				  listed in §E, F, G, or H of this regulation unless the container or inner liner
				  is empty as defined in Regulation .07B of this chapter.
D. Any residue or contaminated soil, water,
				  or other debris resulting from the cleanup of a spill, into or on any land or
				  water, of any commercial chemical product or manufacturing chemical product or
				  manufacturing chemical intermediate having the generic name listed in §E or G
				  or mixtures containing polychlorinated biphenyls (PCBs) at concentrations
				  greater than 50 ppm. The hazardous waste number for these mixtures is MX
				  01.
E. The commercial chemical
				  products, or manufacturing chemical intermediates, or off-specification
				  commercial chemical products or manufacturing chemical intermediates referred
				  to in §§A-D of this regulation are identified as acute hazardous wastes (H) and
				  are subject to the small quantity exclusion defined in Regulation .05C of this
				  chapter. These wastes and their corresponding EPA Hazardous Waste Numbers are:
