LLNL Emergency Management Plan (EPlan) <br />Rev 27 <br />January 2022 <br /> <br /> 14 <br />Site 300: (approximate figures – November 2021) <br />• 214 Active Facilities <br />152 Buildings <br />8 Trailers <br />54 Utilities or Other structures <br />• 19 Shutdown Standby Facilities <br />• » 376,000 gross square feet <br />1.4.1.1 Facility Descriptions <br />Site 200 <br />Site 200 has six facilities or grouping of facilities as determined by EPHAs that could experience <br />events causing the declaration of an Operational Emergency based on the nature of the hazardous <br />materials present. <br />Site 300 <br />Site 300 conducts tests associated with the non-nuclear explosive component of a nuclear <br />weapon. Some facilities at Site 300 store hazardous materials of sufficient quantity that could <br />cause declaration of an Operational Emergency if an incident occurred. However, while there are <br />various locations where hazardous material accidents could occur, the entire site is treated as a <br />single hazardous facility during the hazards assessment process. <br />1.4.1.2 All-Hazards Survey and Hazardous Material Assessment <br />The actual and authorized hazardous material inventories of the Livermore Site 200 and Site 300 <br />facilities are compared with the evaluation criteria screening thresholds prescribed by DOE <br />Order 151.1D to determine the need for further quantitative assessment. Facilities with an <br />inventory of a particular hazardous material in excess of criteria-based values require further <br />evaluation and documentation in the form of a facility-specific EPHA. The EPHAs are updated <br />periodically (every three years) or whenever there are significant changes to operations <br />(e.g., new operations not previously considered or new hazardous material inventories). <br />The LLNL All-Hazards Survey is developed in accordance with local plans/procedures for <br />preparing an all-hazards survey. Most of the facilities listed in the All-Hazards Survey do not <br />require a facility-specific quantitative EPHA. Hazards existing at LLNL include small amounts <br />of chemical hazards such as hydrogen chloride, chlorine, and sodium hydroxide. Radiological <br />hazards include plutonium, uranium, tritium, and transuranic wastes. The results of this <br />evaluation survey are summarized in the current version of the All-Hazards Survey. The latest <br />Emergency Readiness Assurance Plan (ERAP) contains annually updated information on the All- <br />Hazards Survey, EPHAs, and tabulated information related to significant radiological, chemical, <br />and biological hazards authorized in LLNL buildings and facilities.
