7.1 3 <br /> APPENDIX II <br /> EP TOXICITY TEST <br /> Procedure <br /> 1 . A representative sample of the waste to be tested <br /> (minimum size 100 grams) should be obtained using the <br /> methods specified in Appendix I of 40 CFR 261 or any <br /> other method capable of yielding a representative sample <br /> within the meaning of 40 CFR 260 . <br /> 2. The sample should be separated into its component <br /> liquid and solid phases using the method described in <br /> "Separation Procedure" below. If the dry weight of <br /> the solid residue* obtained using this method totals <br /> less than 0 .5% of the original wet weight of the waste, <br /> the residue can be discarded and the operator should <br /> treat the liquid phase as the extract and proceed immedi- <br /> ately to Step 8 . <br /> 3 . The solid material obtained from the Separation <br /> Procedure should be evaluated for its particle size . If <br /> the solid material has a surface area per gram of material <br /> equal to , or greater than, 3 .1 cm2 or passes through a <br /> 9 .5 mm (0.375 inch) standard sieve, the operator should <br /> proceed to Step 4 . If the surface area is smaller or the <br /> *The percent solids is determined by drying the filter pad at <br /> 80°C until it reaches constant weight and then calculating <br /> the percent solids using the following equation: <br /> (weight of pad + solid) - ( tare weight of pad) X 100 % solids <br /> initial wet weight of sample <br />
