Designing and building a plant in a sustainable way means also knowing how to better identify and manage every single change. For this reason, since the early phases of construction, Ital Gas Storage is committed, to a careful and accurate monitoring of noise, dust and vibration.

Acustic monitoring

The noise impact assessment of the activities carried out during the different construction phases of the storage site is one of the monitoring operations carried out by Ital Gas Storage, and will continue even when the storage is operational.

The monitoring is carried out in coordination with ARPA, the Regional Agency for Environmental Protection, at the detection points established by the same agency and located in close proximity to the Central Area and the two clusters (A and B), in order to confirm compliance with the current regulations.

Before beginning construction, the so-called "white noise" (the background noise under normal conditions) was measured, both during the day and at night.

Dust monitoring

The dust monitoring activity is carried out in close cooperation and coordination with the competent authorities, and in particular with ARPA Lombardia, which oversees the company in detection of air quality. The monitoring began at the beginning of 2015 through a detection unit of the PM10 levels in the vicinity of the Central Area – Cluster A, with sampling procedures prescribed by ARPA.

Vibration monitoring

The issue of security has always represented a pillar of the project for Ital Gas Storage.

For this reason, the company has, on a voluntary basis, always adhered to the seismic activity monitoring initiative promoted by the Ministry of Economic Development (MISE) through the UNMIG regulations (General Direction for the MISE Mining and Energy Resources) "Directives and guidelines for the monitoring of seismic activity, soil deformation and pore pressures in the context of human activities", even though the Cornegliano Laudense gas storage site is not included among the cases identified by MISE.

The objective of seismic monitoring activity is to measure the micro-seismicity in a radius of several kilometers from the storage site with a high degree of detail and sensitivity. The monitoring network consists of nine new stations located in different municipalities – including Cornegliano Laudense, Lodi, Lodi Vecchio, Massalengo and Pieve Fissiraga – in addition to those already present in the reference area.

These stations are equipped with technologically advanced seismological instruments and remote data transmission equipment that continuously transmits data to the collection and processing center, managed by OGS (National Institute of Oceanography and Experimental Geophysics), a public research body with an international and independent vocation.
