§ 66261.30 BARCLO CALIFORNIA CODE OF REGULATIO* Title 22
<br />(5) it has an acute inhalation LC30 less than 10,000 parts per million
<br />as a gas or vapor-,
<br />(6) it has an acute aquatic 96 -hour LC50 less than 500 milligrams per
<br />liter when measured in soft water (total hardness 40 to 48 milligrams per
<br />liter of calcium carbonate) with fathead minnows (Pimephales prome-
<br />las), rainbow trout (Salmo gairdnen) or golden shiners (Notemigonus
<br />crysoleucas) according to procedures described in Part 800 of the "Stan-
<br />dard Methods for the Examination of Water and Wastewater (16th Edi-
<br />tion)," American Public Health Association, 1985 and "Static Acute
<br />Bioassay Procedures for Hazardous Waste Samples," California Depart-
<br />ment of Fish and Game, Water Pollution Control Laboratory, revised No-
<br />vember 1988 (incorporated by reference, see section 66260.11), or by
<br />other test methods or test fish approved by the Department, using test
<br />samples prepared or meeting the conditions for testing as prescribed in
<br />subdivisions (c) and (d) of Appendix II of this chapter, and solubilized,
<br />suspended, dispersed or emulsified by the cited procedures or by other
<br />methods approved by the Department;
<br />it contains any of the following substances at a single or combined
<br />concentration equal to or exceeding 0.001 percent by weight:
<br />(A) 2 -Acetylaminofluorene (2 -AAF);
<br />(B) Acrylonitrile;
<br />(C) 4-Aminodiphenyl;
<br />(D) Benzidine and its salts;
<br />(E) his (Chloromethyl) ether (BCME);
<br />(F) Methyl chloromethyl ether;
<br />(G) 1,2-Dibromo-3-chloropropane (DBCP);
<br />(H) 3,31-Dichlorobenzidine and its salts (DCB);
<br />(I) 4 -Dimethylaminoazobenzene (DAB);
<br />(J) Ethyleneimine (EL);
<br />(K) alpha -Naphthylamine (1 -NA);
<br />(L) beta -Naphthylamine (2 -NA);
<br />(M) 4-Nitrobiphenyl (4 -NBP);
<br />(N) N-Nitrosodimethylamine (DMN);
<br />(0) beta -Propiolactone (BPL);
<br />(P) Vinyl chloride (VCM);
<br />(8) it has been shown through experience or testing to pose a hazard
<br />to human health or environment because of its carcinogenicity, acute tox-
<br />icity, chronic toxicity, bioaccumulative properties or persistence in the
<br />environment.
<br />(b) A waste containing one or more materials which exhibit the charac-
<br />teristic of toxicity because the materials have the property specified in
<br />subsection (a)(5) of this section may be classified as nonhazardous pur-
<br />suant to section 66260.200 if the waste does not exhibit any other charac-
<br />teristic of this article and is not listed in article 4 of this chapter and its
<br />head space vapor contains no such toxic materials in concentrations ex-
<br />ceeding their respective acute inhalation LC50 or their LCLO. The head
<br />space vapor of a waste shall be prepared, and two milliliters of it shall be
<br />sampled using a five milliliter gas-tight syringe, according to Method
<br />5020 in "Test Methods for Evaluating Solid Waste, Physical/Chemical
<br />Methods," SW -846, 2nd edition, U.S. Environmental Protection
<br />Agency, 1982 (incorporated by reference, see section 66260.11). The
<br />quantity in milligrams of each material, which exhibits the characteristic
<br />of toxicity because it has the property specified in subsection (a)(5) of
<br />this section, in the sampling syringe shall be determined by comparison
<br />to liquid standard solutions according to the appropriate gas chromato-
<br />graphic procedures in Method 8010, 8015, 8020, 8030 or 8240 in "Test
<br />Methods for Evaluating Solid Waste, Physical/Chemical Methods,"
<br />SW -846, 3rd edition, U.S. Environmental Protection Agency, 1986 (in-
<br />corporated by reference, see section 66260.11). The concentration of
<br />each material in the head space vapor shall be calculated using the fol-
<br />lowing equation:
<br />QA 29.8ml I
<br />CA = x x
<br />MW mmole 2 x 10-6M3
<br />where C (in parts per million) is the concentration of material A in head
<br />space vapor, Q (in milligrams) is the quantity of material A in sampling
<br />syringe and MW (in milligrams per millimole) is the molecular weight
<br />of material A. Where an acute inhalation LC50 is not available, an LC50
<br />measured for another time (t) may be converted to an eight-hour value
<br />with the following equation:
<br />Eight-hour LC50 = (t/8) x (t -hour LC50).
<br />(c) A waste containing one or more materials which exhibit the charac-
<br />teristic of toxicity because the materials have either of the properties spe-
<br />cified in subsection (a)(3) or (a)(4) of this section may be classified as
<br />nonhazardous pursuant to section 66260.200 if the waste does not exhibit
<br />any other characteristic of this article and is not listed in article 4 of this
<br />chapter and the calculated oral LD50 of the waste mixture is greater than
<br />5,000 milligrams per kilogram and the calculated dermal LD50 is greater
<br />than 4,300 milligrams per kilogram by the following equation:
<br />Calculated oral or dermal LD50 = 100
<br />Ax n %
<br />E
<br />x = 1 TAx
<br />where %Ax is the weight percent of each component in the waste mixture
<br />and TAX is the acute oral or dermal LD50 or the acute oral LDLO of each
<br />component.

<br />Article 4. Lists of RCRA Hazardous Wastes
<br />§ 66261.30. General.
<br />(a) A waste is a RCRA hazardous waste if it is listed in this article, un-
<br />less it has been excluded from this list pursuant to 40 CFR sections
<br />260.20 and 260.22 or is categorized as a non-RCRA hazardous waste
<br />pursuant to section 66261.101. Wastes shall only be listed in this article
<br />if they are listed in 40 CFR Part 261 Subpart D.
<br />(b) The Department will indicate the USEPA Administrator's basis for
<br />listing the classes or types of wastes listed in this article by employing one
<br />or more of the following Hazard Codes:
<br />Ignitable Waste (I)
<br />Corrosive Waste (C)
<br />Reactive Waste (R)
<br />Acute Hazardous Waste (H)
<br />Toxic Waste (T)
<br />Appendix VII of this chapter identifies the constituent which caused
<br />the USEPA Administrator to list the waste as a Toxic Waste (T) as in-
<br />cluded in sections 66261.31 and 66261.32.
<br />(c) Each RCRA hazardous waste listed in this article is assigned an
<br />EPA Hazardous Waste Number which precedes the name of the waste.
<br />This number shall be used in complying with the notification require-
<br />ments of Health and Safety Code section 25153.6 and certain record-
<br />keeping and reporting requirements under chapters 12 through 15, 18,
<br />and 20 of this division.
