The sound during a blowdown can be as loud as an airplane engine and may last anywhere from a few minutes to multiple hours, depending on the amount of pipe being depressurized. As the flow of gas gradually slows down, the noise also lessens.
Residents living in close proximity to the planned blowdown location will receive notification of the blowdown prior to the work beginning.
For details, see the Blowdown Notification Fact Sheets.
