§ 11.1 - Purpose.

This part contains rules and regulations providing for an Emergency Alert System (EAS). The EAS provides the President with the capability to provide immediate communications and information to the general public at the National, State and Local Area levels during periods of national emergency. The rules in this part describe the required technical standards and operational procedures of the EAS for analog AM, FM, and TV broadcast stations, digital broadcast stations, analog cable systems, digital cable systems, wireline video systems, wireless cable systems, Direct Broadcast Satellite (DBS) services, Satellite Digital Audio Radio Service (SDARS), and other participating entities. The EAS may be used to provide the heads of State and local government, or their designated representatives, with a means of emergency communication with the public in their State or Local Area.

[72 FR 62132, Nov. 2, 2007]
§ 11.2 - Definitions.

The definitions of terms used in part 11 are:

(a) National Emergency Message (EAN). The National Emergency Message (formerly called the Emergency Action Notification or Presidential alert message) is the notice to all EAS Participants and to the general public that the EAS has been activated for a national emergency. EAN messages that are formatted in the EAS Protocol (specified in § 11.31) are sent from a government origination point to broadcast stations and other entities participating in the National Public Warning System, and are subsequently disseminated via EAS Participants. Dissemination arrangements for EAN messages that are formatted in the EAS Protocol (specified in § 11.31) at the State and local levels are specified in the State and Local Area plans (defined at § 11.21). A national activation of the EAS for a Presidential National Emergency Message with the Event code EAN as specified in § 11.31 must take priority over any other message and preempt it if it is in progress.

(b) EAS Participants. Entities required under the Commission's rules to comply with EAS rules, e.g., analog radio and television stations, and wired and wireless cable television systems, DBS, DTV, SDARS, digital cable and DAB, and wireline video systems.

(c) Wireline Video System. The system of a wireline common carrier used to provide video programming service.

(d) Intermediary Device. An intermediary device is a stand-alone device that carries out the functions of monitoring for, receiving and/or acquiring, and decoding EAS messages formatted in the Common Alerting Protocol (CAP) in accordance with § 11.56, and converting such messages into a format that can be inputted into a separate EAS decoder, EAS encoder, or unit combining such decoder and encoder functions, so that the EAS message outputted by such separate EAS decoder, EAS encoder, or unit combining such decoder and encoder functions, and all other functions attendant to processing such EAS message, comply with the requirements in this part.

[59 FR 67092, Dec. 28, 1994, as amended at 67 FR 18508, Apr. 16, 2002; 87 FR 67823, Nov. 10, 2022]
§ 11.18 - EAS Designations.

(a) A Primary Entry Point (PEP) is a private or commercial radio broadcast station that cooperatively participates with FEMA to provide EAS alerts to the public. PEPs are the primary source of initial broadcast for a Presidential Alert. A PEP is equipped with back-up communications equipment and power generators designed to enable it to continue broadcasting information to the public during and after disasters of national significance. The National Public Warning System (formerly called the Primary Entry Point System) is a nationwide network of broadcast stations and satellite operators used to distribute EAS alerts formatted in the EAS Protocol. FEMA is responsible for designating broadcast stations as PEPs.

(b) A National Primary (NP) is an entity tasked with the primary responsibility of receiving the National Emergency Message from a PEP and delivering it to an individual state or portion of a state. In states without a PEP, the NP is responsible for receiving the National Emergency Message from an out-of-state PEP and transmitting it to the public and other EAS Participants in the state. Multiple entities may be charged with primary responsibility for delivering the National Emergency Message.

(c) A State Primary (SP) is an entity tasked with initiating the delivery of EAS alerts other than the National Emergency Message.

(d) A State Relay (SR) is an entity not otherwise designated that is charged with retransmitting EAS alerts for the purpose of being monitored by a Local Primary or Participating National. SRs must monitor or deliver EAS alerts as required by the State EAS Plan.

(e) A State Relay Network (SRN) is a network composed of State Relay (SR) sources, leased common carrier communications facilities, or any other available communication facilities. The network distributes State EAS messages originated by the Governor or designated official. In addition to EAS monitoring, satellites, microwave, FM subcarrier, or any other communications technology may be used to distribute State emergency messages.

(f) A Local Primary (LP) is an entity that serves as a monitoring assignment for other EAS Participants within the state. LP sources may be assigned numbers (e.g., LP-1, 2, 3) and are relied on as monitoring sources by other EAS Participants in the Local Area. An LP may monitor any other station, including another LP, as set forth in the State EAS Plan, so long as doing so avoids creating a single point of failure in the alert distribution hierarchy.

(g) A Participating National (PN) is an EAS Participant that transmits national, state, or Local Area EAS messages, and is not otherwise designated within the State EAS Plan. PNs monitor LPs or other sources as set forth in the State EAS Plan.

[87 FR 67823, Nov. 10, 2022]
§ 11.20 - [Reserved]
§ 11.21 - State and Local Area plans and FCC Mapbook.

EAS plans contain guidelines which must be followed by EAS Participants' personnel, emergency officials, and National Weather Service (NWS) personnel to activate the EAS. The plans include the EAS header codes and messages that will be transmitted by key EAS sources (NP, LP, SP and SR). State and local plans contain unique methods of EAS message distribution such as the use of the Radio Broadcast Data System (RBDS). The plans also include information on actions taken by EAS Participants, in coordination with state and local governments, to ensure timely access to EAS alert content by non-English speaking populations. The plans must be reviewed and approved by the Chief, Public Safety and Homeland Security Bureau (Bureau), prior to implementation to ensure that they are consistent with national plans, FCC regulations, and EAS operation. The plans are administered by State Emergency Communications Committees (SECC). The Commission encourages the chief executive of each State to establish an SECC if their State does not have an SECC, and if the State has an SECC, to review the composition and governance of the SECC. The Bureau will review and approve plans, including annual updated plans, within 60 days of receipt, provided that no defects are found requiring the plan to be returned to the SECC for correction and resubmission. If a plan submitted for approval is found defective, the SECC will be notified of the required corrections, and the corrected plan may be resubmitted for approval, thus starting the 60-day review and approval period anew. The approval dates of State EAS Plans will be listed on the Commission's website.

(a) State EAS Plans contain guidelines that must be followed by EAS Participants' personnel, emergency officials, and National Weather Service (NWS) personnel to activate the EAS. The Plans include information on actions taken by EAS Participants, in coordination with state and local governments, to ensure timely access to EAS alert content by non-English speaking populations. State EAS Plans must be updated on an annual basis. State EAS Plans must include the following elements:

(1) A list of the EAS header codes and messages that will be transmitted by key EAS sources (NP, LP, SP, and SR);

(2) Procedures for state emergency management officials, the National Weather Service, and EAS Participant personnel to transmit emergency information to the public during an emergency via the EAS, including the extent to which the state's dissemination strategy for state and local emergency alerts differs from its strategy for the National Emergency Message;

(3) Procedures for state and local activations of the EAS, including a list of all authorized entities participating in the State or Local Area EAS;

(4) A monitoring assignment matrix, in computer readable form, clearly showing monitoring assignments and the specific primary and backup path for the National Emergency Message (EAN) from the NPWS to all key EAS sources (using the uniform designations specified in § 11.18) and to each station in the plan, organized by operational areas within the state. If a state's emergency alert system is capable of initiating EAS messages formatted in the Common Alerting Protocol (CAP), its EAS State Plan must include specific and detailed information describing how such messages will be aggregated and distributed to EAS Participants within the state, including the monitoring requirements associated with distributing such messages;

(5) State procedures for conducting special EAS tests and Required Monthly Tests (RMTs);

(6) A list of satellite-based communications resources that are used as alternate monitoring assignments and present a reliable source of EAS messages; and

(7) The SECC governance structure utilized by the state in order to organize state and local resources to ensure the efficient and effective delivery of a National Emergency Message, including the duties of the SECC, the membership selection process utilized by the SECC, and the administrative structure of the SECC.

(8) Certification by the SECC Chairperson or Vice-Chairperson that the SECC met (in person, via teleconference, or via other methods of conducting virtual meetings) at least once in the twelve months prior to submitting the annual updated plan to review and update the plan.

(b) The Local Area plan contains procedures for local officials or the NWS to transmit emergency information to the public during a local emergency using the EAS. Local plans may be a part of the State plan. A Local Area is a geographical area of contiguous communities or counties that may include more than one state.

(c) The FCC Mapbook is based on the consolidation of the monitoring assignment matrices required in each State EAS Plan with the identifying data contained in the ETRS. The Mapbook organizes all EAS Participants according to their State, EAS Local Area, and EAS designation. EAS Participant monitoring assignments and EAS operations must be implemented in a manner consistent with guidelines established in a State EAS Plan submitted to the Commission in order for the Mapbook to accurately reflect actual alert distribution.

(d) EAS Participants are required to provide the following information to their respective State Emergency Communications Committees (SECC) within one year from the publication in the Federal Register of a notice announcing the approval by the Office of Management and Budget of the modified information collection requirements under the Paperwork Reduction Act of 1995 and an effective date of the rule amendment:

(1) A description of any actions taken by the EAS Participant (acting individually, in conjunction with other EAS Participants in the geographic area, and/or in consultation with state and local emergency authorities), to make EAS alert content available in languages other than English to its non-English speaking audience(s),

(2) A description of any future actions planned by the EAS Participant, in consultation with state and local emergency authorities, to provide EAS alert content available in languages other than English to its non-English speaking audience(s), along with an explanation for the Participant's decision to plan or not plan such actions, and

(3) Any other relevant information that the EAS Participant may wish to provide, including state-specific demographics on languages other than English spoken within the state, and identification of resources used or necessary to originate current or proposed multilingual EAS alert content.

(e) Within six months of the expiration of the one-year period referred to in subsection (d) of this section, SECCs shall, as determined by the Commission's Public Safety and Homeland Security Bureau, provide a summary of such information as an amendment to or as otherwise included as part of the State EAS Plan filed by the SECC pursuant to this section 11.21.

(f) EAS Participants shall, within 60 days of any material change to the information they have reported pursuant to paragraphs (d)(1) and (2) of this section, submit letters describing such change to both their respective SECCs and the Chief, Public Safety and Homeland Security Bureau. SECCs shall incorporate the information in such letters as amendments to the State EAS Plans on file with the Bureau under this section 11.21.
