1072019 ANNUAL AND CORPORATE RESPONSIBILITY REPORT

In order to continue increasing the amount of water recycled and reused, we are working on identifying flows that can be reused or recycled, as well as impro- ving the treatment technologies at our facilities, adapted to their geographi- cal and logistical particularities. A good example is the case of the La Rabida refinery (Huelva), in which a portion of the water leaving the treatment plant is incorporated as plant water, and the re- verse osmosis treatment reject current is used as an input to the cooling towers. Work is currently underway on an ultra- filtration and reverse osmosis plant at the Gibraltar - San Roque refinery (Cádiz) which will enable the volume of water recycled to reach 20% of the total water consumed. At the exploration and production facili- ties, various alternatives have been iden- tified to reduce our water consumption such as its reuse during the crude oil desalination process, its recycling after passing through the treatment plant in the fire protection system pumps, the use of recycled water for the preparation of

chemical reagents and for spraying and cleaning roads, or the internal transfer of treated production water for use as industrial water in drilling and reconditio- ning operations.

When we make our discharges to the environment, we strictly respect the ma- ximum levels of the legally determined parameters, and we attempt to improve our performance. No body of water or habitat is significantly affected by dis- charges of water and/or runoff from our production plants or business units. The only discharge of wastewater, previously treated in a biological effluent treatment plant, to a sensitive area (which has di- fferent categories of conservation, inter- national, national and local) occurs at our Palos chemical facility, whose discharge parameters are, in 100% of cases, below the limits established in the discharge authorisation. Also, the new filtration treatment plant at the San Roque refi- nery was started up in 2019, reducing the content of suspended solids in the efflu- ent with the aim of bringing it down to below 35 ppm.
