LLNL-AM-428479 <br /> 1 . INTRODUCTION <br /> This Contingency Plan identifies personnel responsibilities, emergency equipment, and <br /> required actions necessary to mitigate potential incidents at the Waste Accumulation <br /> Areas (WAAs) located at the Lawrence Livermore National Laboratory (LLNL) <br /> Experimental Test Site 300 (Site 300) in San Joaquin County as shown in Figure 1. <br /> This Plan is designed to prepare personnel to minimize hazards to human health and <br /> the environment from fires and explosions, or any sudden or non-sudden releases of <br /> hazardous, radioactive, or mixed waste constituents to the air, ground surface, or water <br /> from waste stored in the WAA. <br /> Site 300 currently has one WAA. The location of the WAA is shown in Figure 2 and <br /> identified in Table 1. As programmatic needs change, it may become necessary to <br /> establish additional WAAs at Site 300. The WAA is a small, regularly-monitored storage <br /> area where waste can be accumulated and stored temporarily. Hazardous and mixed <br /> waste can be stored or accumulated in a WAA for up to 90-days, after which it must be <br /> transferred to a Department of Toxic Substances Control (DTSC) authorized onsite <br /> treatment or storage facility or an authorized offsite treatment, storage, or disposal <br /> facility (TSDF). <br /> Hazardous, radioactive, or mixed waste is referred to as "waste" in this document. <br /> Radioactive waste has been included in this Plan as a "Best Management Practice" to <br /> aid in response, where appropriate. However, radioactive waste is not regulated by <br /> DTSC under this Plan. <br /> This Contingency Plan is divided into two parts: <br /> 1. The first part, referred to as the "General Plan," is general information that is <br /> applicable to the existing and any subsequent WAAs. The General Plan includes <br /> Sections 1-7 and Appendices A—C. <br /> 2. The second part, referred to as the "Site-specific Plan," contains site-specific <br /> information for the existing and any subsequent WAAs. Site-specific Plans are <br /> included in Appendix D. <br /> A copy of the Contingency Plan (including the Site-specific Plan) will be distributed to <br /> regulatory agencies and to public service organizations, such as local fire departments and <br /> hospitals that may be called upon to provide emergency services. A copy of the General <br /> Plan with the appropriate Site-specific Plan will be located at each WAA, so it can be used <br /> in case of an emergency. <br /> S300 WAA Contingency Plan 2 September2018 <br />
