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 26.13.02.14 - Toxicity Characteristic

Current through Register Vol. 51, No. 14, July 12, 2024
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:

					 becomes the regulatory level.
4 If o-, m-, and p-cresol

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.
