Title 22 En =ental Health Standards—Hazardous
<br />§ 66261.22. Characteristic of Corrosivity.
<br />(a) A waste exhibits the characteristic of corrosivity if representative
<br />samples of the waste have any of the following properties:
<br />(1) it is aqueous and has a pH less than or equal to 2 or greater than or
<br />equal to 12.5, as determined by a pH meter using either the EPA test
<br />method for pH or an equivalent test method approved by the Department
<br />pursuant to section 66260.21. The EPA test method for pH is specified
<br />as Method 9040 in "Test Methods for Evaluating Solid Waste, Physical/
<br />Chemical Methods," SW -846, 3rd edition and updates (incorporated by
<br />reference, see section 66260.11);
<br />(2) it is a liquid and corrodes steel (SAE 1020) at a rate greater than
<br />6.35 mm (0.250 inch) per year at a test temperature of 550C (1 300F) as
<br />determined by the test method specified in NACE Standard TM -01-69
<br />as standardized in "Test Methods for Evaluating Solid Waste, Physical/
<br />Chemical Methods," SW -846, 3rd edition and updates (incorporated by
<br />reference, see section 66260.11) or an equivalent test method approved
<br />by the Department pursuant to section 66260.21;
<br />(3) it is not aqueous and, when mixed with an equivalent weight of wa-
<br />ter, produces a solution having a pH less than or equal to 2 or greater than
<br />or equal to 12.5, as determined by a pH meter using either Method 9040
<br />in "Test Methods for Evaluating Solid Waste, Physical/Chemical Meth-
<br />ods," SW -846, 3rd edition and updates (incorporated by reference, see
<br />section 66260.11) or an equivalent test method approved by the Depart-
<br />ment pursuant to 66260.21;
<br />(4) it is not a liquid and, when mixed with an equivalent weight of wa-
<br />ter, produces a liquid that corrodes steel (SAE 1020) at a rate greater than
<br />6.35 mm (0.250 inch) per year at a test temperature of 550C (130°F) as
<br />determined by the test method specified in NACE Standard TM -01-69
<br />as standardized in "Test Methods for Evaluating Solid Waste, Physical/
<br />Chemical Methods," SW -846, 3rd edition and updates (incorporated by
<br />reference, see section 66260.11) or an equivalent test method approved
<br />by the Department pursuant to 66260.21.
<br />(b) A waste that exhibits the characteristic of corrosivity specified in
<br />subsection (a)(1) or (a)(2) of this section has the EPA Hazardous Waste
<br />Number of D002.
<br />NOTE: Authority cited: Sections 25141, 25159, 58004 and 58012, Health and

<br />Health and Safety Code and 40 CFR Section 261.22.

<br />§ 66261.23. Characteristic of Reactivity.
<br />§ 66261.24
<br />(a) A waste exhibits the characteristic of reactivity if representative
<br />samples of the waste have any of the following properties:
<br />(1) it is normally unstable and readily undergoes violent change with-
<br />out detonating;
<br />(2) it reacts violently with water;
<br />(3) it forms potentially explosive mixtures with water;
<br />(4) when mixed with water, it generates toxic gases, vapors or fumes
<br />in a quantity sufficient to present a danger to human health or the environ-
<br />ment;
<br />(5) it is a cyanide or sulfide bearing waste which, when exposed to pH
<br />conditions between 2 and 12.5, can generate toxic gases, vapors or fumes
<br />in a quantity sufficient to present a danger to human health or the environ-
<br />ment;
<br />(6) it is capable of detonation or explosive reaction if it is subjected to
<br />a strong initiating source or if heated under confinement;
<br />(7) it is readily capable of detonation or explosive decomposition or
<br />reaction at standard temperature and pressure;
<br />(8) it is a forbidden explosive as defined in 49 CFR section 173.51 (as
<br />amended April 20, 1987), or a Class A explosive as defined in 49 CFR
<br />section 173.53 (as amended April 5, 1967) or a Class B explosive as de-
<br />fined in 49 CFR section 173.88 (as amended May 19, 1980).
<br />(b) A waste that exhibits the characteristic of reactivity has the EPA
<br />Hazardous Waste Number of D003.
<br />NOTE: Authority cited: Sections 208, 25141 and 25159, Health and Safety Code.
<br />Reference: Sections 25117, 25120.2, 25141, 25159 and 25159.5, Health and Safe-
<br />ty Code and 40 CFR Section 261.23.

<br />§ 66261.24. Characteristic of Toxicity.
<br />(a) A waste exhibits the characteristic of toxicity if representative sam-
<br />ples of the waste have any of the following properties:
<br />(1) when using the Toxicity Characteristic Leaching Procedure
<br />(TCLP), test Method 1311 in "Test Methods for Evaluating Solid Waste,
<br />Physical/Chemical Methods," EPA Publication SW -846, third edition
<br />and Updates (incorporated by reference in section 66260.11 of this divi-
<br />sion), the extracts from representative samples of the waste contain any
<br />of the contaminants listed in Table I of this section at a concentration
<br />equal to or greater than the respective value given in that table unless the
<br />waste is excluded from classification as a solid waste or hazardous waste
<br />or is exempted from regulation pursuant to 40 CFR section 261.4. Where
<br />the waste contains less than 0.5 percent filterable solids, the waste itself,
