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.

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. __________________________________________________________________________________
