Preventing impacts 3.3.2.4.1 The prevention of impacts is based on an “in-depth defence” approach. The following protection methods are in place at all industrial sites, specifically: maintaining the integrity of means of protection to provide a barrier between ■ circuits containing or carrying radioactive or chemical substances and the environment; control of operations, management of effluents, their transfer and storage prior ■ to release; maintaining and inspecting ultimate structures such as sumps, retention systems, ■ unloading areas and pipes; ensuring that the soil surface remains free from radiological and/or chemical ■ contamination at industrial sites; monitoring the physico-chemical and/or radiological properties of groundwater ■ directly beneath sites; building retention tanks at storage sites for products and materials that could ■ pollute the soil; reinforcing safeguards when transporting and storing fuel (double-walled ■ containers) or waste (suitable containers); ensuring the availability of emergency kits in the event of spillages and carrying ■ out the corresponding drills; developing operational procedures and high levels of awareness among ■ operators and service providers through suitable training. These preventive measures are based on facilities hazard studies and are enriched at the time of periodic reviews. The Sustainable Development Policy adopted at Group level stipulates that for each activity presenting a risk of pollution, a soil and groundwater management approach including pollution prevention must be launched before 2019 Optimising soil use 3.3.2.4.2 The Group’s industrial activities may entail some localised soil pollution. Action plans are in place to control these situations across all of the Group’s sites. They consist of four stages: site surveys; identification of those that are potentially polluted; soil analysis on potentially polluted sites (sensitive areas first); introduction of a monitoring system for sources of pollution and drawing up a management plan and considering possible remediation depending on future use and regulatory requirements. In 2018, several baseline reports were prepared in response to the European IED Directive: thermal sites of Brennilis, Dirinon, Arrighi, Gennevilliers, Vaires sur Marne, Montereau, Martigues, Blénod, Bouchain, Le Havre and Cordemais as well as the production units of EDF Luminus (Seraing and Angleur) and the island electricity systems. They did not reveal significant contamination. The soil management plans are awaiting approval from the authorities for the sites of Chinon, Blayais and work is in progress on the sites of Flamanville and Hinkley Point, on the sites managed by Dalkia and the sites of the thermal fleet in France and of IES being decommissioned. To reduce the probability of pollution, the Group uses its considerable synergies to replace hazardous products with products that are less harmful to the environment and public health, where this is technically feasible. With this in mind, EDF, Enedis (3) and ÉS are continuing with their programmes to decontaminate equipment containing PCBs (4) and PCTs (5) of more than 50 ppm. These action plans continued in 2018 are on target. The 31 December 2019 target of eliminating 50% of the original fleet was already achieved during the year. Complete disposal is set for the end of 2025. The target of eliminating 50% of the original fleet by the end of 2019 was met before the deadline. EDF R&D, EDF IES, EDF PEI, SOCODEI, Dalkia and the thermal and nuclear generation sites no longer have any equipment exceeding the threshold.

This expertise is provided to the scientific community and local authorities in the form of innovative solutions; for example in 2018: the city of Villiers-sur-Marne decided to set up a global benchmark demonstrator ■ of indoor and outdoor air quality. For its deployment, it will rely on EDF's scientific expertise (1) . The challenge to be met in the context of building the new Marne-Europe district is to allow as many people as possible to breathe good quality air, at a controlled cost. The innovative character of the demonstrator is based on its global “from the street to the living room” approach, with, in both cases, the desire to use digital modelling (2) to create a tool to help with the dimensioning and visualisation of the optimal plan for air circulation. The work carried out as part of the research programme will be used to deploy air treatment services in urban and peri-urban areas; in Paris, Lille and the department of Haute Savoie, Enedis' vehicles are equipped ■ with a network of air quality sensors called Pollutrack. This is the first company fleet to contribute to improving air quality by detecting and measuring pollution caused by the finest particles which are the most dangerous for health; Citelum is implementing its know-how in terms of smart lighting and connected ■ services to support Airparif in its policy of improving air quality in Ile-de-France. Thus, as part of the creation of AIRLAB, Airparif's laboratory of innovative air quality solutions, Citelum is testing a prototype of connected street furniture to measure mobility flows in real time. Corrective actions and changes in infrastructure and behaviour can be implemented when coupled with Airparif's air quality monitoring data. In future, this system based on urban infrastructure could be an additional connected service for a “smart city”; in addition, EDF contributes to preventive and research initiatives on the health ■ impact of air pollution through the Association for Prevention of Air Pollution (APPA) and the Inter-professional Technical Centre for Studies on Air Pollution (CITEPA). In 2018, sharing its good practices, EDF contributed to the National Clean Air Day, organised by the Ministry of Ecological and Solidarity Transition. Soil 3.3.2.4

EDF materiality matrix identifies soil pollution as one of its material issues (issue no. 22 Management of milieux: soil and water pollution). This refers to the management of pollution and contamination risks that are likely to cause biological, physical and chemical changes in land and aquatic milieux, and to their effects on health. As part of its industrial and tertiary activities, the Group owns, or uses under concession, large land assets. This is why the environmental policies of the various Group entities aim to optimise the use of land and protect soil and groundwater against any impacts. Soil use is monitored as part of the actions related to biodiversity (see section 3.2.6 “Committed to biodiversity”)
