Water, air, soil and noise self-monitoring

3Context and challenges3

Self-monitoring is based on the trust and responsibility given to the operator.
It implies the operator’s vigilance (data verification, in particular data clarity, data communication to the Inspectorate with explanatory notes if necessary etc.).
Its credibility depends on the instigation, within the company, of a solid chain of measures (sampling, conservation, analysis, exploitation).

Self-monitoring makes it possible to increase the number of analyses, thereby enhancing the administrative action of the Inspectorate, who would not otherwise be able to carry out these analyses.

The communication of measurement results, accompanied by appropriate comments, therefore enables the Inspectorate of classified installations to ensure that the industrial operator has implemented all appropriate measures necessary to run his installations with regard to their impact on the environment.

The trust placed in the industrial operator does not preclude monitoring. In order for the self-monitoring process to remain credible, unannounced monitorings are carried out on the initiative of the Inspectorate (paid for by the operator) by independent organisations contracted by the Inspectorate.


Stipulated by the order of 2 February 1998 for permit holding installations or by ministerial orders defining general operational requirements for the installations with a declaration obligation, it consists of the operator sampling or contracting an external company to sample, under their responsibility, wastewater or air pollutants, then analysing the samples to verify compliance with the limit values set by the prefectural permit order or ministerial order defining the general operational requirements applicable to the installations.

In terms of noise, the order of 23 January 1997 or technical instruction of 20 August 1985 stipulates the periodic renewal of the facility’s noise emission measurement (generally every 3 to 5 years).

The results must be made available to the Inspectorate of classified installations for at least 5 years and communicated upon a simple request.
