As part of PPL Corporation's commitment to protecting the health and safety of the public, the company will replace all of the emergency sirens located within the 10-mile radius around the Susquehanna nuclear power plant.

"The sirens are a vital part of our plant's comprehensive emergency plan that helps ensure our communities are well-prepared for any type of emergency," said Lou Ramos, community relations manager for the power plant. "The sirens allow our company and local emergency management agencies to quickly alert our neighbors to tune in to local television or radio stations for information."

PPL is scheduled to install the new sirens and poles close to the current ones between April and September.

"The upgrades will ensure we have reliable sirens well into the future," Ramos said. "Also, the new sirens will allow us to easily identify a false alarm quickly and make appropriate repairs."

The upgraded sirens have a new design and will rotate on their poles to ensure full broadcast coverage. Fewer of the upgraded models are required to cover the same area, although more may be added if testing reveals the need. Once tests prove the entire new system works successfully, PPL will remove the current sirens and poles.

"Ensuring the new system works well before removing the current system means our communities always have this essential function available," Ramos said. "We will restore affected property when the replacements are completed and do our best to minimize impact to property owners. We appreciate their patience while the upgrades are in progress."

PPL will maintain its current schedule of siren tests. If the installation process is unexpectedly delayed, PPL will conduct the full-scale siren test using the current system and then perform another full-scale siren test with the new system at a later date.

With the new system, PPL Susquehanna will perform the same routine tests throughout the year to ensure the sirens continue to work. Routine testing includes an annual full-scale test where sirens are actually sounded, quarterly growl tests where the motor is started and turned off before the siren sounds, and electronic, silent tests every two weeks.

The Susquehanna plant, located in Luzerne County about seven miles north of Berwick, is owned jointly by PPL Susquehanna LLC and Allegheny Electric Cooperative Inc. and is operated by PPL Susquehanna.
