DRUMORE TOWNSHIP, Pa. – A warning system to be used in the event of an emergency at Exelon Power’s Muddy Run Pumped Storage Facility in Lancaster County will be tested next Thursday.

During the test, scheduled for approximately 10 a.m. on Oct. 13, a brief tone will sound, followed by the words “This is a Test, This is a Test.”  The test will last approximately two minutes. No action is necessary.

The system, designed to warn the owners and residents of cottages along a stretch of Conowingo Pond in the event of an emergency at Muddy Run, consists of six sets of loudspeakers mounted atop poles both upstream and downstream of the facility. These poles were installed in Drumore Township, Lancaster County, and Lower Chanceford and Peach Bottom townships in York County. Installation of the system, training of Exelon employees and quiet testing of the system was performed in 2003 and 2004.

Although not required by the Federal Energy Regulatory Commission (FERC), the agency that oversees the facility, Exelon Power installed the system as an additional method of warning the public, specifically cottage owners along the Susquehanna River.

As part of Muddy Run’s comprehensive emergency preparedness plans, the system will be tested every three months, on the second Thursday of January, April, July and October of each year at approximately 10 a.m.

Before each quarterly test, Exelon Power will send notifications to area authorities informing them of the test. These notifications will be sent to each township and county along the Lower Susquehanna River between the Norman Wood Bridge (Route 372) and the Peach Bottom Atomic Power Station, as well as to area newspapers.

In the event of a real emergency, a tone will sound, followed by the words, “This is an Emergency, Please Move to Higher Ground, This is an Emergency, Please Move to Higher Ground.”

Muddy Run Pumped Storage Facility is an electric generating station operated by Exelon Power. Exelon Power also operates the Conowingo Hydroelectric Generating Station further downstream on the Susquehanna River. Muddy Run, which was built in 1968, includes the 1,000-acre, 250 foot deep Upper (or Power) Reservoir.  This reservoir, located in Martic and Drumore townships, Lancaster County, was created by the construction of a 4,800-foot-long, 250-foot-high, rock-filled dam. The dam is inspected regularly, is equipped with extensive instrumentation to monitor its condition, and undergoes regular maintenance. The dam has been maintained in excellent condition and continues to perform well.
