===Primary Entry Point stations===
The National Public Warning System, also known as the '''Primary Entry Point''' ('''PEP''') stations, is a network of 77 radio stations that are, in coordination with FEMA, used to originate emergency alert and warning information to the public before, during, and after incidents and disasters. PEP stations are equipped with additional and backup communications equipment and power generators designed to enable them to continue broadcasting information to the public during and after an event.<ref name=":5" /><ref name=":6" /><ref name=":7" />

Beginning with [[WJR]] Detroit and [[WLW]] Cincinnati in 2016, FEMA began the process of constructing transportable studio shelters at the transmitters of 33 PEP stations, which feature broadcasting equipment, emergency provisions, a rest area, and an air filtration system. NPWS project manager Manny Centeno explained that these shelters were designed to "[expand] the survivability of these stations to include an all hazards platform, which means chemical, biological, radiological air protection and protection from electromagnetic pulse."<ref name=":5">{{cite web|url=https://www.radioworld.com/news-and-business/wlw-pep-station-to-test-new-studio-shelter|title=WLW PEP Station to Test New Studio Shelter|date=October 22, 2018|website=Radio World|language=en-US|access-date=July 30, 2019|archive-url=https://web.archive.org/web/20190401160113/https://www.radioworld.com/news-and-business/wlw-pep-station-to-test-new-studio-shelter|archive-date=April 1, 2019|url-status=live}}</ref><ref name=":6">{{cite web|url=https://radioink.com/2018/10/22/fema-upgrading-wlw/|title=FEMA Upgrading WLW|date=October 22, 2018|website=Radio Ink|language=en-US|access-date=July 30, 2019|archive-url=https://web.archive.org/web/20190730192226/https://radioink.com/2018/10/22/fema-upgrading-wlw/|archive-date=July 30, 2019|url-status=live}}</ref><ref name=":7">{{cite web|url=http://www.insideradio.com/free/in-hardening-eas-lynchpins-fema-puts-confidence-in-radio/article_890c20a4-d824-11e8-8a9f-d33e31890575.html|title=In Hardening EAS Lynchpins, FEMA Puts Confidence In Radio.|website=Insideradio.com|date=25 October 2018 |language=en|access-date=July 30, 2019|archive-url=https://web.archive.org/web/20190729071743/http://www.insideradio.com/free/in-hardening-eas-lynchpins-fema-puts-confidence-in-radio/article_890c20a4-d824-11e8-8a9f-d33e31890575.html|archive-date=July 29, 2019|url-status=live}}</ref>
