Md. Code Regs. 26.13.02.19 - Discarded Commercial Chemical Products, Off-Specification Species, Containers, and Spill Residues of These

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:
