Code of Massachusetts Regulations › 310 CMR - DEPARTMENT OF ENVIRONMENTAL PROTECTION › Title 310 CMR 30.000 - Hazardous waste › GENERAL PROVISIONS › Section 30.125 - Toxicity Characteristic (TC)

Current through Register 1525, July 5, 2024
(1) A waste
				exhibits the characteristic of toxicity if, using the Toxicity Characteristic
				Leaching Procedure incorporated by reference in
				310 CMR
				30.155 or an equivalent method, the extract
				from a representative sample of the waste contains any of the contaminants
				listed in 310 CMR 30.125: Table 1 at a concentration equal to or greater than
				the respective value given in that table. Where the waste contains less than
				0.5% filterable solids, the waste itself, after filtering using the methodology
				incorporated by reference in
				310 CMR
				30.155, is considered to be the extract for
				the purposes of 310 CMR 30.125.
(2)
				A waste that exhibits the characteristic of toxicity has the EPA Hazardous
				Waste Number specified in 310 CMR 30.125: Table 1 which corresponds to the
				toxic contaminant causing it to be hazardous.

Quantitation limit is greater than the calculated regulatory
				  level. The quantitation limit becomes the regulatory level.
4 If o-, m-, p-Cresol
				  concentration cannot be differentiated, the total cresol (D026) concentration
				  is used. The regulatory level of total cresol is 200 mg/l.
