1 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 mg/l.
2 Quantitation limit is greater than the calculated regulatory level. The quantitation limit therefore becomes the regulatory level.

a STLC and TTLC values are calculated on the concentrations of the elements, not the compounds.
b In the case of asbestos and elemental metals, the specified concentration limits apply only if the substances are in a friable, powdered or finely divided state. Asbestos includes chrysotile, amosite, crocidolite, tremolite, anthophyllite, and actinolite.
c Excluding barium sulfate.
d If the soluble chromium, as determined by the TCLP set forth in Appendix I of chapter 18 of this division, is less than 5 mg/l, and the soluble chromium, as determined by the procedures set forth in Appendix II of chapter 11, equals or exceeds 560 mg/l and the waste is not otherwise identified as a RCRA hazardous waste pursuant to section 66261.100, then the waste is a non-RCRA hazardous waste.
e Excluding molybdenum disulfide.

where C (in parts per million) is the concentration of material A in head space vapor, Q (in milligrams) is the quantity of material A in sampling syringe and MW (in milligrams per millimole) is the molecular weight of material A. Where an acute inhalation LC50 is not available, an LC50 measured for another time (t) may be converted to an eight-hour value with the following equation:
Eight-hour LC50 = (t/8) x (t-hour LC50).

where % Ax is the weight percent of each component in the waste mixture and TAx is the acute oral or dermal LD50 or the acute oral LDLO of each component.
