SOP#NMS-ANA-SOP-SWDC REV#1.1 Title:Solid Wst.Disposal Characterization Effective Date 10/11/2012 <br /> 11. CALCULATIONS FOR WEIGHING WET SAMPLES <br /> 11.1. Calculation of the solid weight fraction (S): <br /> S = e A=mass after drying <br /> B=original mass <br /> 11.2. Calculation of amount of as-received waste (M): <br /> a_00 <br /> M = — <br /> s <br /> 11.3. Calculation of dry test sample weight M(d): <br /> M(d) = MxS <br /> 11.4. Calculation of mass of water in sample M(w): <br /> M(w) = M —M(d) <br /> 11.5. Calculation of mass of extraction fluid (Me): <br /> M(e) = 2014(d) —M(w) <br /> 12. DATA ASSESMENT AND QUALITY CONTROL MEASURES <br /> 12.1. This procedure depends upon a precise leach time. Step (10.6) must be performed <br /> according to specifications. <br /> 12.2. Analytical results may be affected by the type of filter used. Always filter according <br /> to (10.8). <br /> 12.3. Assessment of data: Following analysis of solution generated in this procedure, <br /> results are compared to Table 1 which lists the limits from 40 CFR part 268.48 <br /> with respect to Universal Treatment Standards for land disposal and RCRA limits <br /> for hazardous/non-hazardous determination. <br /> 12.3.1.Table 1 <br /> Analyte UTS limits (m /L) RCRA limits (mg/L) <br /> Arsenic 5.0 5.0 <br /> Barium 21 100 <br /> Cadmium 0.11 1 <br /> Chromium 0.60 5 <br /> Lead 0.75 5 <br /> Plato Malozemoff Technical Facility I Newmont Metallurgical Services <br /> The information contained in this report is confidential and proprietary. 5 <br />
