5.2.2 WATER AND SOIL POLLUTION

Petroleum products released into water (in kg) checks have been performed confirming the absence of pollutants. In the loading/unloading zones of the storage sites for tank trucks , the retention platforms are purpose-designed for each type of product, and, as a general rule, connected to oil-water separators linked to treatment plants or buffer basins. Water is tested at discharge points at least every half-year, and monthly at the outflows from treatment plants. Weekly or monthly checks are carried out on nearly all sites to verify that there is no floating pollution in the groundwater monitoring wells downstream of facilities. Support and services activity For vessel chartering , Rubis Énergie calls on the services of a specialist company that vets the vessel in question. This specialist company collects information relating to the vessel’s condition (construction date, maintenance, etc.), as well as the operator’s Support and services activity (refining) could also give rise to water and soil pollution in the event of accidental spillage or leaks, as well as through the use of wastewater (desalination water, stripping treatments), bulk tank drain water and ballast waste water. Discharges of suspended solids and petroleum products into water declared by the Rubis Énergie refinery in 2017 were up 8.7% and down 37.8% respectively compared with 2016. Excess discharge of suspended solids was associated with the loss of performance of a lamella clarifier, which will be replaced by more powerful equipment in 2018. The reduction in volumes of petroleum products released into water was due to more reliable units (reduction in quantities of process water to be treated) and an increased abatement in physico-chemical treatment. 2017 2016 260 218 230 350

2017 immediately detect any loss of product due to faulty equipment and/or improper practises or fraud. Rainwater liable to have been polluted through contac t with roadways is increasingly being treated before discharge into the environment; stations are equipped with systems for the collection and treatment of rainwater whenever road repair work is planned. Storage activity Tanks containing hazardous products , and associated pipework, undergo systematic inspections at storage sites in accordance with international standards during regular mandatory on-site visits. Moreover, to prevent groundwater and soil pollution in the event of accidental spillage, nearly all storage tanks are installed in watertight retention basins (lined with concrete or clay compounds). These basins are kept shut. They are only opened manually after The petroleum products distribution ac tivit y (gas stations and tanks on customers’ premises) is essentially only concerned by water and soil pollution from the risk of accidental fuel spills or leaks in the pipeworks or tanks. In the storage activity , in 2017, the change in the level of suspended solids at Rubis Terminal sites was not significant compared with 2016. The increase in the rate of petroleum products released into water was due to increased operations at a site in Rouen, including draining lines in preparation for the commencement of works, without, however, exceeding regulatory thresholds. Storage activity at Rubis Terminal and Rubis Énergie may generate soil pollution, especially as a result of bulk tank overflows, spillage, bulk tank and/or pipe leaks. 1,743 3,854

The risks of contamination of water and soil related to the Group’s operations can result from accidental spillages of stored and/ or transported products (see chapter 4, section 4.1). Some of the pollution identified to date results from operations prior to the Group’s presence on the site in question; for such pollution, a program to ensure compliance with the Group’s standards is being implemented. Broadly speaking, the Group invests significantly and gradually on sites to improve the safety of its facilities and to eliminate the risk of pollution as far as possible. Analysis by business line Water and soil pollution issues are not the same for all of the Group’s businesses.

Measures to prevent and/or contain water and soil pollution Petroleum products distribution activity Equipment used at Rubis Énergie gas stations that is liable to generate soil pollution (mainly tanks and piping) is checked regularly (particularly in respect of its integrity and watertightness), and is gradually being replaced by double-wall technology. This includes double-wall underground tanks and pipes equipped with leak detectors which provide continuous oversight to guard against any possible pollution. At the same time, Rubis Énergie is strengthening its preventive maintenance programs for this equipment (detailed in section 5.2.1 ), and is working to improve the safety/environmental training of station managers (see section 5.1.4 ), to ensure that they have the resources available to
