The main sources of noise from our activities are compressor stations, usually located in rural areas along the gas pipeline network, pressure reduction stations, which connect distribution and transportation gas pipelines at different operating pressures, and the LNG regasification plant.
In order to contain the acoustic impact of our installations, we first pursue a policy of prevention. This consists of correctly sizing the installations during the design phase, and drawing up an acoustic impact forecast. Measures taken consist of installing soundproof cabinets, acoustic flues, low-noise valves, mufflers on operating vents and burying the pipes.
During 2009, the Company also continued specific measurement campaigns to verify the level of sound emitted by our installations, conducted both by specialised internal personnel and by outside companies qualified to provide this service.
