12 PMP 3150 PCP. 100 APPENDIX B MIXED WASTE PROGRAM 1.0 ~Pur oee 1.1 This program .is designed to establish guidelines and procedural requirements which will provide adequate assurance that the plant is in compliance with current restrictions on the burial of low-level radioactive waste mixed with hazardous materials. These requirements are applicable to all radioactive wastes packaged for burial.
- 2. 0 ~Polio 2.1 All chemicals used within the controlled area of the plant will be utilized in accordance with PMI-2160, which includes restrictions on their disposal.
3.0 Definitions F 1 Mixed Waste - Mixed low-level radioactive and hazardous waste (mixed waste) is waste that satisfies .the definition of low-level radioactive waste .(LLW) in the Low-Level Radioactive Waste Policy Amendments Act of 1985 (LLRWPAA) and contains hazardous waste that either (1) is listed as a hazardous waste in Subpart D of 40 CFR Part 261 or (2) causes the LLW to exhibit any of the hazardous waste characteristics identified in Subpart C of 40 CFR Part 261.
3.2 Hazardous Characteristics The four characteristics that a waste may exhibit that result in classified as a hazardous waste are:
it being ignitability (Part 263,.21); corrosivity (Part 261.22); reactivity (Part 261.23); and EP toxicity (Part 261.24).
4.0 Identification of Mixed Waste 4.1 Determine which waste streams have the =potential for containing mixed waste. This determination should be done by applying knowledge of the hazard characteristic of the waste in light of the materials or the processes used.
Page 1'f 2 Revision 3
12 PMP 3150 PCP.100 APPENDIX B 4.2 Determine whether the radioactive waste contains any hazardous wastes specifically listed in Subpart D of 40 CFR Part 261, from PMI-2160, Chemical Permits.
4.3 Determine whether the radioactive waste contains hazardous waste that causes the waste to exhibit any of the hazardous waste characteristics identified in Subpart C of 40 CFR 261 by collecting representative samples for testing.
4.4 Samples shall be processed into their normal form for transportation and burial. For example, sludges are solidified for burial so the sample should be solidified prior to testing. The parameters used to solidify the sample should be the same as would be used for full scale processing.
4.5 Have the final waste form samples analyzed for a particular hazardous chemical if one has been identified in 4.3, or for the hazardous characteristics of 4.4.
4.6 If the analysis classified as a results in the waste not being mixed waste it may be disposed under normal plant procedures.
4 ' If the analysis results in the waste being classified as a mixed waste it should be held on site until such time that an appropriate disposal facility is available, unless approved per Section 6.0.
5.0 Sam lin Fre uenc 5.1 As a minimum, samples of radwaste resin, evaporator concentrates and sludges, if available, should be collected annually and sent offsite for RCRA Waste Characterization.
tions 6.1 The Barnwell burial site (licensee: Chem. Nuclear) may receive waste that has been treated by acceptable methods to render it non-hazardous and therefore not subject to the jurisdiction of the Resources Conservation and Recovery Act (RCRA). Waste which may contain discreet quantities of hazardous or toxic materials may be evaluated for disposal by Chem-Nuclear and such evaluations provided to the South Carolina Department of Health and Environmental Control (DHEC) for consideration of approval.
Page 2 of 2 Revision 3
12 PMP 3150 PCP. 100 APPENDIX C PARAMETERS FOR THE OPERATION OF THE WASTE EVAPORATOR SYSTEM The limit of volume reduction for the Waste Evaporator System is dependent on the concentration of various chemical and radiochemical parameters.
The boron concentration should be kept within the limits listed in Table 1, to prevent crystallization of boron in the evaporator package. If the boron concentration increases above this limit, sodium hydroxide should be added to maintain an acceptable pH and to convert the boric acid to a more soluble form.
The concentration of chlorides should be kept below the limit listed in Table 1. Chlorides must be controlled to prevent corrosion of the evaporator's internal components.
The gross By activity of the evaporator bottoms should be kept below the limit listed in Table 1. The activity is maintained, to insure that the evaporator bottoms may be solidified and shipped in compliance with applicable regulations.
Samples will he taken periodically by the Chemistry Section during waste evaporator operation to monitor these chemical and radiochemical parameters.
Prior to attempting solidification of waste evaporator bottoms, the bottoms should be sampled and found to be within the limits listed in Table 2.
TABLE 1 Boron Concentration 25,000 ppm pH 7.4 9.2 Gross Sy Total 0. 2 pCi/cc Chlorides 10, 000 ppm TABLE '2 Boron Concentration 0 40,000 ppm pH 7.4 9.2 or > 11.5
