Roll-out of the system and

corrective action plans used

for non-conformities These environmental audits have identified

positive actions taken on the worksites,

but also environmental non-conformities

that need to be dealt with quickly to avoid

any risk of incident and to ensure that

the commitments undertaken for this major

project are met. In view of the increasing pace

of work on the Grand Paris Express, Société

du Grand Paris has undertaken to develop

and implement a new process for monitoring

the correct resolution of all environmental

non-conformities identified during audits or

by any other source. The first results reveal

contractors have responded enthusiastically

and are actively supporting the process.

Specific audits for managers

of disposal sites In 2020, specific audits were carried out

at intermediate treatment sites and final

disposal sites. These audits are used to check

compliance with the commitments described

in the partnership agreements and the

best practice charter signed between

the managers of these sites and Société

du Grand Paris. These include commitments

such as the use of the digital traceability tool

for spoil developed by Société du Grand Paris,

the installation of weighing equipment at

the entrance to their sites, and the regulatory

compliance of their facilities.

ENVIRONMENTAL AUDITS IN 2020

Audit and control policy for the implementation of environmental requirements during

construction

Société du Grand Paris relies on its project managers to oversee the environmental monitoring

of its worksites. Project managers have various tools at their disposal for inspecting and

monitoring compliance with environmental requirements, both regulatory and contractual,

designed by Société du Grand Paris to ensure that the works and the project are executed in an

exemplary way.

In addition to this extensive monitoring, Société du Grand Paris set up its environmental audit

system to provide a second, independent and factual assessment of progress made at its

worksites. These audits, which are scheduled every six months, are part of an overall approach

to improving the environmental quality of worksites and provide the programme manager with

the opportunity to request that corrective actions be implemented if the environmental

requirements are not fully met.

Three types of entity are audited: construction companies, project managers and managers

of final disposal or intermediate spoil management sites.

In some cases, measurements, samples and analyses (water quality, air quality, noise, etc.) may

be taken during these audits to verify compliance with the thresholds applicable to the worksites

programme managed by Société du Grand Paris and to quantify the level of any nuisance.
