Environmental Protection Department Operations and Regulatory Affairs Division Contingency Plan for Site 300 Waste Accumulation Area(s)

Abstract

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