LLNL Emergency Management Plan (EPlan) <br />Rev 27 <br />January 2022 <br /> <br /> 77 <br />LEDO. EMD has established a specific email account (EOC@llnl.gov) that is provided to DOE <br />HQ for notification by email messages. This email address is set-up to forward any email <br />received at the ACRECC email account (which is an ACFD email domain) to all EMDOs and all <br />ORDOs. Due to the important nature of these messages, the on-duty EMDO will contact <br />ACRECC to verify that they have acknowledged the message with DOE HQ and that they have <br />passed the message information to the LEDO. <br />6.2 Communications <br />Emergency communications is defined as the ability of emergency responders to exchange <br />information via data, voice, and video as authorized, to complete their missions. Emergency <br />responders at all levels must have interoperable and seamless communications to manage <br />emergency response, establish command and control, maintain situational awareness, and <br />function under a common operating picture for a broad scale of incidents. <br />Emergency communications consists of three primary elements: <br />1. Operability – The ability of emergency responders to establish and sustain <br />communications in support of mission operations. <br />2. Interoperability – The ability of emergency responders to communicate among <br />jurisdictions, disciplines, and various levels, using a variety of frequency bands, as <br />needed and as authorized. System operability is required for system interoperability. <br />3. Continuity of Communications – The ability of emergency response agencies to <br />maintain communications in the event of damage to or destruction of the primary <br />infrastructure. <br />6.2.1 Secure Communications <br />LLNL has the capability for secure communications using a secure telephone unit and secure <br />facsimile for connectivity to DOE/NNSA HQ Operations Center. NNSA’s ECN/VTC equipment <br />is located in buildings at LLNL and would be available if required by the ERO during an <br />emergency. <br />6.2.2 Communications with Offsite Agencies <br />The primary communications system for official initial offsite notification is AtHoc. This is a <br />web-based digital communications system. Once the EOC is operational, telefax is the primary <br />means of offsite notification and AtHoc becomes the back-up. <br />The National Warning System (NAWAS) is the special purpose telephone system that provides <br />the capability for selective dissemination of warnings and emergency information nationwide, <br />within FEMA Regional areas, within National Weather Service regional forecast areas, and <br />within state-wide areas. The primary National Warning Center is the FEMA Operations Center <br />located at the Mt. Weather Emergency Assistance Center in Berryville, Virginia.
