Footnotes to Table UTS
1 | CAS means Chemical Abstract Services. When the waste code and/or regulated constituents are described as a combination of a chemical with it's salts and/or esters, the CAS number is given for the parent compound only. |
2 | Concentration standards for wastewaters are expressed in mg/l and are based on analysis of composite samples. |
3 | Except for Metals (EP or TCLP) and Cyanides (Total and Amenable) the nonwastewater treatment standards expressed as a concentration were established, inpart, based upon incineration in units operated in accordance with the technical requirements of 40 CFR part 264, subpart O or 40 CFR part 265, subpart O, or based upon combustion in fuel substitution units operating in accordance with applicable technical requirements. A facility may comply with these treatment standards according to provisions in 40 CFR 268.40(d) . All concentration standards for nonwastewaters are based on analysis of grab samples. |
4 | Both Cyanides (Total) and Cyanides (Amenable) for nonwastewaters are to be analyzed using Method 9010C or 9012B, found in "Test Methods for Evaluating Solid Waste, Physical/Chemical Methods," EPA Publication SW-846, as incorporated by reference in 40 CFR 260.11 , with a sample size of 10 grams and a distillation time of one hour and 15 minutes. |
5 | These constituents are not "underlying hazardous constituents" in characteristic wastes, according to the definition at § 268.2(i) . |
6 | [Reserved] |
7 | This constituent is not an underlying hazardous constituent as defined at § 268.2(i) of this Part because its UTS level is greater than its TC level, thus a treatment selenium waste would always be characteristically hazardous, unless it is treated to below its characteristic level. |
8 | This standard is temporarily deferred for soil exhibiting a hazardous characteristic due to D004-D011 only. |
