SCE&G to test emergency sirens at Lake Murray and V.C. Summer

Cayce, SC – SCE&G, a subsidiary of Dominion Energy, will conduct two separate tests of siren warning systems Tuesday, Jan. 8, in two separate Midlands locations.

At noon, SCE&G will activate the siren warning system along the Lower Saluda River as part of the Lake Murray Dam emergency action plan. A full, three-minute sounding of the sirens is conducted on the second Tuesday of January each year. One-minute functional tests are conducted at noon on the second Tuesday of each month during the remainder of the year. In the unlikely event of a potential failure of the Lake Murray Dam and the backup dam, the sirens would alert the public to tune in to local radio or television stations for information.

At approximately 1 p.m., SCE&G will sound the 109 sirens located within a 10-mile radius of V.C. Summer Nuclear Station in Fairfield County near Jenkinsville. As part of its regular testing program, SCE&G sounds its sirens in Fairfield, Newberry, Richland and Lexington counties each year for three minutes and each quarter for less than a minute.

Area residents are reminded that the sounding of sirens during this time period is only a test. In the unlikely event of an actual emergency at the plant, the sirens would sound with no prior notice and would alert area residents to tune to an Emergency Alert System radio or television station for further instructions.

SCE&G and other companies that operate U.S. nuclear facilities maintain robust emergency preparedness plans to protect the health and safety of the public. SCE&G conducts multiple emergency response drills each year to validate its emergency response plan, which is independently evaluated every two years by the Nuclear Regulatory Commission and the Federal Emergency Management Agency. Information about siren tests, nuclear generation and emergency planning is mailed to residents within 10 miles of V.C. Summer Nuclear Station in the annual emergency preparedness calendar.
