Md. Code Regs. 26.13.02.14 - Toxicity Characteristic
A. A
solid waste, except manufactured gas plant waste, exhibits the characteristic
of toxicity if, using the Toxicity Characteristic Leaching Procedure, Test
Method 1311 in "Test Methods for Evaluating Solid Waste, Physical/Chemical
Methods", EPA Publication SW-846, which is incorporated by reference in COMAR
26.13.01.05 o A(4), the extract
from a representative sample of the waste contains any of the contaminants
listed in Table 1 at the concentration equal to or greater than the respective
value given in that table. When the waste contains less than 0.5 percent
filterable solids, the waste itself, after filtering using the methodology
outlined in Test Method 1311, is considered to be the extract for the purpose
of this section.
B. A solid waste
that exhibits the characteristic of toxicity has the EPA hazardous waste number
specified in the following Table 1, which corresponds to the toxic contaminant
causing it to be hazardous:

1 Hazardous waste number.
2 Chemical Abstracts Service number.
3 Quantitation limit is greater than the calculated regulatory level. The quantitation limit, therefore, becomes the regulatory level.
4 If o-, m-, and p-cresol concentrations cannot be differentiated, the total cresol (D026) concentration is used. The regulatory level of total cresol is 200 milligrams per liter.
C. Clarification
Concerning Manufactured Gas Plant Waste. Manufactured gas plant waste that
would exhibit the characteristic of toxicity in the absence of the exception
provided in §A of this regulation may not be managed in a landfill that is
permitted, licensed, or registered to manage municipal solid waste.
