(a] A solid waste exhibits the characteristic of reactivity if a representative sample of the waste has any of the following properties: (1) It is normally unstable and readily undergoes violent change without detonating. (2) It reacts violently with water. (3) It forms potentially explosive mixtures with water. (4) When mixed with water, it generates toxic gases, vapors or fumes in a quantity sufficient to present a danger to human health or the environment (5) It is a cyanide or sulfide bearing waste which, when exposed to pH conditions between 2 and 12.5, can generate toxic gases, vapors or fumes in a quantity sufficient to present a danger to human health or the environment. (6) It is capable of detonation or explosive reaction if it is subjected to a strong initiating source or if heated under confinement. (7) It is readily capable of detonation or explosive decomposition or reaction at standard temperature and pressure. (8} It is a forbidden explosive as defined in 49 CFR 173.51, or a Class A explosive as defined in 49 CFR 173.53 or a Class B explosive as defined in 49 CFR 173.88. (b) A solid waste that exhibits the characteristic of reactivity, but is not listed as a hazardous waste in Subpart D, has the EPA Hazardous Waste Number of D003. 3 261.24 Characteristic of EP Toxicity. (a) A solid waste exhibits the characteristic of EP toxicity if, using the test methods described in Appendix II or equivalent methods approved by the Administrator under the procedures set forth in 260.20 and 260.21, the extract from a representative sample of the waste contains any of the contaminants listed in Table I at a concentration equal to or greater than the respective value given in that Table. Where the waste contains less than 0.5 percent filterable solids, the waste itselfr after filtering, is considered to be the extract for the purposes of this section. (b) A solid waste that exhibits the characteristic of EP toxicity, but is not listed as a hazardous waste in Subpart D, has the EPA Hazardous Waste Number specified in Table I which corresponds to the toxic contaminant causing it to be hazardous.

Samples collected using the sampling protocols listed below, for sampling waste with properties similar to the indicated materials, will be considered by the Agency to be representative of the waste. Extremely viscous liquid--ASTM Standard D140-70 Crushed or powdered material-- ASTM Standard D346-75 Soil or rock-like material--ASTM Standard D420-69 Soilllke material--ASTM Standard D1452-65 Fly Ash-like material--ASTM Standard 2234-76 [ASTM Standards are available from ASTM, 1916 Race St, Philadelphia, PA 19103] Containerized liquid wastes--"COLIWASA" described`in `T est Methods for the Evaluation of Solid Waste.

'These methods are also described in "Samplers and Sampling Procedures for Hazardous Wsate Streams.'' EPA 800/2-00-018. January I860. Appendix n -- EP Toxicity Test brought into contact with well mixed Procedure extraction fluid. A. Extraction Procedure (EP) 5. After the solid material and deionized water are placed in the 1. A representative sample of the waste to be tested [minimum size 100 grams] should be obtained using the methods specified in Appendix I or any other methods capable of yielding a representative sample within the meaning of Part 260. [For detailed guidance on conducting the various aspects-of the EP see 'Test Methods for the Evaluation of Solid Waste, Physical/ Chemical Methods," SW-846, U.S. Environmental Protection Agency Office of Solid Waste, Washington, D.C. 20460.'] 2. The sample should be separated into its component liquid and solid phases using the method described in "Separation Procedure" below. If the solid residue3obtained using this method totals less than 0.5% of the original weight of the waste, the residue can be discarded and the operator should treat the liquid phase as the extract and proceed immediately to Step 8. 3. The solid material obtained from the Separation Procedure should be evaluated for its particle size. If the solid material has a surface area per gram of material equal to, or greater than, 3.1 cm3or passes through a 9.5 mm (0.375 .inch) standard sieve, the operator should proceed to Step 4. If the surface extractor, the operator should begin agitation and measure the pH of the solution in the extractor. If the pH is greater than 5.0. the pH of the solution Bhould be decreased to 5.0 0.2 by adding 0.5 N acetic acid. If the pH is equal to or less than 5.0. no acetic acid should be added. The pH of the solution should be monitored, as described below, during the course of the extraction and if the pH rises above 5.2, 0.5N acetic acid should be added to bring the pH down to 5.0 0.2. However, in no event shall the aggregate amount of acid added to the solution exceed 4 ml of acid per gram of solid. The mixture should be agitated for 24 hours and maintained at 20a-40s C (68104* F) during this time. It is ----- recommended that the operator monitor and adjuBt the pH during the course of the extraction with a device such as the Type 45-A pH Controller manufactured by Chemtrix, Inc., Hillsboro, Oregon 07123 or its equivalent, in conjunction with a metering pump and reservoir of 0.5N acetic acid. If such a system is not available, the following manual procedure shall be employed: (a) A pH meter should be calibrated in accordance with the manufacturer's specifications. (b) The pH of the solution should be checked and, if necessary, 0.5N acetic acid area is smaller or the particle size larger ^ should be manually added to the extractor than specified above, the solid material 'u n til the pH reaches 5.0 0.2. The pH.of the should be prepared for extraction by crushing, cutting or grinding the material so that it passes through a 9.5 mm (0.375 inch) sieve or. if the material.is in a single piece, by subjecting the material to the "Structural Integrity Procedure" solution should be adjusted at 15,30 and 60 minute intervals, moving to the next longer Interval if the pH does not have to be adjusted more than 0.5N pH units. (c) The adjustment procedure should be continued for at least 6 hours. (d) If at the end of the 24-hour extraction described below. period, the pH of the solution is not below 5.2 4. The solid material obtained in Step 3 should be weighed and placed in an extractor with 16 times its weight of deionized water. Do not allow the material to dry prior to weighing. For and the maximum amount of acid (4 ml per gram of solids) has not been added, the pH should be adjusted to 5.0 0.2 and the extraction continued for an additional four hours, during which the pH should be adjusted at one hour intervals. purposes of this test, an acceptable extractor is one which will impart sufficient agitation to the mixture to not only prevent stratification of the sample and extraction fluid but also insure that all sample surfaces are continously 6. At the end of the 24 hour extraction period, deionized water should be added to the extractor in an amount determined by the following equation: V = (20)(W) --16fW) --A V = ml deionized water to be added 'Copie may be obtained from Solid Waste Information, U.S. Environmental Protection Agency, 2BW.
